| Name | Faction | Description | In Combat |
|---|---|---|---|
 Tyrfing | Ether Mutants | The Hollow Investigative Association has been studying Tyrfing's behavioral patterns, and research results show that its seemingly unbalanced stance of swaying and skewing is, in fact, a highly efficient stance for launching successive slashing attacks. Due to its frequent appearances and aggressive behavior, Tyrfing has been identified as one of the most deadly Ethereals in the Hollow, particularly for certain Hollow personnel. When faced with a shielded enemy, it relentlessly launches attacks until either its enemy or itself is destroyed. "Perhaps... they don't actually hate us, but just think of us as punching bags for practice?" | During combat, Tyrfing will perform melee attacks. |
 Alpeca | Ether Mutants | The Hollow Investigative Association has limited research on Alpeca. After briefly studying its behavioral pattern of spewing liquid Ether, the Association classified Alpeca as a low-threat Ethereal and ended its investigation. Scholars once showed great interest in observing how Alpeca spews liquefied Ether and even commissioned surveys for closer observation. Experienced investigators have been avoiding such tasks for unknown reasons, however. "Run! They're spitting again... Oh, no! My new clothes!" | During combat, Alpeca will perform scattered ranged attacks. |
 Faun | Ether Mutants | A living humanoid Ether that was first spotted in the Hollow in the New Eridu metro. It once raised debate among the Hollow Investigative Association, as some believed it to be living Ether converted from the Corrupted, while others claimed it to be pure living Ether affected by the Hollow environment. The Association considers it of low threat due to its limited intelligence, but one should never underestimate them, as they usually appear in groups. "Have you ever been late or fined because of a red light? Feels terrible, right?" "Well, here's your chance to blow off some steam!" | During combat, Faun tends to perform charged heavy attacks that are hard to interrupt. |
 Hoplitai | Ether Mutants | While categorized by the Hollow Investigative Association as a "low threat" Ethereal, Hoplitai prove to be a formidable opponent for novice Hollow Raiders and investigators. Its forelimbs are covered in a thick inert Ether matter, serving as both a tough shield and an intimidating weapon. The only drawback is its top-heavy appearance, making it not look very clever. "Alright, guys... Check out this sorry excuse... This is Hoplitai." "When Ethereals gather together to play rock-paper-scissors, this idiot always plays paper!" | During combat, Hoplitai uses a shielded arms charge at opponents and block attacks. |
 Blastcrawler | Ether Mutants | According to research reports conducted by the Hollow Investigative Association, Blastcrawlers, with their low mobility and causing only small explosions, are classified as a "low-threat," "non-concern" lower-tier Ethereal. However, astute businessmen have recognized the opportunities presented by their rounded bodies and short legs. A film titled "Roll Over, Little Blastcrawler" gained significant popularity, leading to the sale of merchandise like Blastcrawler dolls and pillows at remarkably high prices. "I didn't expect their dolls to be more deadly than the real deal... On your wallet at least. Looks like I'll be surviving on instant noodles next month, Billy..." | During combat, Blastcrawler self-destructs. |
 Strike Jaeger | Rebel Soldiers | A light infantry unit of the New Eridu Defense Force. Armed with combat knives and small Ether explosives as their primary weapons, they emphasize mobility and stealth. Often deployed as scouts or members of reconnaissance teams, they rely on exceptional maneuverability for tasks such as surprise attacks, scouting, pursuit, and assassination. In Hollow-related operations, they serve as excellent vanguards, using their close combat skills to easily overpower ordinary invaders or lower-level living Ether beings. "Masters of the dagger? More like crafty grenadiers. Pretending to be all fancy with their daggers, when most of their opponents are clearly taken out by grenades!" | During combat, Strike Jaeger slides to get close to targets or tosses out knives with delayed explosions. |
 Light Jaeger | Rebel Soldiers | As the New Eridu Defense Force's signature combat unit, qualified Light Jaegers and Scout Jaegers can freely switch between various combat modes. Whether using a knife in close combat or the Falcon-MK3 Ether energy gun at long range, they can tailor their tactics to the target's weaknesses. And when their opponent is in disarray they launch an offensive without hesitation. "I saw that guy with a knife and was preparing for a fair fight... I didn't expect him to suddenly pull out a gun." | During combat, Light Jaeger will provide continual fire support. |
 Rookie Jaeger | Rebel Soldiers | Rookie Jaegers and Private Jaegers play a crucial role as vanguards in the Defense Force's Hollow special operations. Equipped with the Coyote-PE7 Ether cutter, which boasts a high-frequency vibration cutting blade effective at deterring smaller enemies. Engaging Ethereals in close-quarters combat demands exceptional courage, or perhaps madness. "Strictly speaking, that can't be considered a standardized anti-Hollow operation... Those lunatics just seem to enjoy brawling with Ethereals for fun." | During combat, Rookie Jaeger performs melee attacks. |
 Guard Jaeger | Rebel Soldiers | As a vital offensive and defensive unit in the Defense Force's tactical squads, Guard Jaegers and Patrol Jaegers not only carry "Coyote-PE7" heavy Ether cutters but also inert Ether blast shields, providing cover for tactical squads in complex battlefield environments. As a high-defense unit, the extraordinary weight of the shield affects their combat mobility. Without strict training, an ordinary person would find it challenging to lift such a shield. "Come back and submit your application once you've hit the gym!" | During combat, Guard Jaeger uses its shield to both significantly reduce DMG and Daze taken, and also counterattack. |
 Grenadier Jaegers | Rebel Soldiers | Grenadier Jaegers and Demolition Jaegers are equipped with a modified version of the Mamba-TG3 Bazooka, featuring special ammunition containing active Ether incendiary agents. This weapon enables them to swiftly destroy enemy mech units and eliminate large Ethereals within the Hollows. To counteract the recoil and ensure accurate aim, they are required to undergo special weapon-grip training. Interestingly, Defense Force statistics indicate recruits excelling in this program often possess prior experience in photography. "Wanna know how to use this thing? It's like using a shoulder-mounted camera." "Just lock onto your target, pull the trigger, and say..." "Hey, idiot!... Say cheese!" | During combat, Grenadier Jaeger provides heavy ranged fire support. |
| Unknown Unit | Public Security | Unknown unit. Further investigation is needed. | ??? |
 Mandrake | Ether Mutants | Mandrake derive their name from a toxic herb. The scholar who initially assigned the name believed there was a resemblance between the two solely based on their appearance. While blooming, Mandrake emit heat rays targeting nearby objects, while sturdy leaves anchor it firmly to the ground, preventing uprooting. When threatened, Mandrake may use their sharp leaves for self-defense. Similar to the legend of their namesake, Mandrake cries can be highly deadly. "Stay away! It's gonna bloom any second now!" | During combat, different Mandrakes provide periodic ATK/Shield buffs to adjacent units. |
| Raider | Thugs | Among the ranks of Ether thieves, Raiders and Looters serve as the core members, possessing both technical expertise and combat skills. Their Electric Resonance Detection Devices emit powerful currents that are used to detect Ether ore and also function as formidable weapons during armed raids. Occasionally mistaken for illegal fishermen, they pay little attention to such misconceptions. After all, with their extremely lethal electro-shockers, they don't really care whether their targets are fish or humans... "If you encounter individuals armed with electrified harpoons, whether near a river, lake, or Hollow, please report it immediately to Public Security!" | During combat, Hollow Thug - Raider will charge from a long distance, potentially colliding with obstacles along the way — creating the perfect opportunity to counterattack. |
| Pyromaniac | Thugs | For Pyromaniacs and Arsonists, robbing passersby is merely a side hustle. Deep down, they consider themselves as adept bartenders who actively seek excitement. With precision and skill, they expertly blend various types of Ether into their beverages, effortlessly concocting bottles of highly flammable and explosive "exclusive brew." Unlike other brutal Hollow Raiders, they often offer their victims a choice. If the victim agrees to pay the toll, they extend the courtesy of a free drink. However, if the victim declines, the flammable "exclusive brew" will be forcefully shattered upon their head. "How about we trick those guys into drinking their own weapon stash?" | During combat, Hollow Thug - Pyromaniac will sometimes bombard using a hail of molotov cocktails. |
 Miasmic - Blastcrawler | Corrupted | A fallen creation, reshaped in deep, tainted darkness. The Miasma Blastcrawler wears crimson red, yet still can't shake off its "low threat" stigma, as its movement speed and blast radius remain— unchanged... However, the Association has repeatedly issued warnings, urging investigators to guard against the miasma smoke released after its explosion. If inhaled carelessly, a moment of disorientation is enough for even an Elite Investigator to perish in the ever-changing Hollows. "Red team is ready! Here comes the green team walking towards us..." | After being corrupted by Miasma, Miasmic - Blastcrawler becomes extremely unstable, leaving behind Miasma residue that can trigger another explosion after it self-detonates. A well-timed Defensive Assist against its leap can redirect the blast in your favor. |
| Poacher | Thugs | Most of the thugs who spend their time in the Hollows exhibit serious mental problems or peculiar quirks. Fortunately, the Poachers and the Rustlers within the gang have managed to maintain their sanity while embracing the filthy methods of traditional villains. Cowardly and cunning, they excel in the art of concealing themselves within the shadows and launching surprise attacks on their targets. They would never choose to attack head-on if they could ambush. Their composite hand crossbows, though limited in power, produce minimal noise when fired. Seasoned Poachers often seize the perfect moment and immobilize their unsuspecting prey with a single well-aimed shot. "I used to be a Public Security officer, then I took an arrow in the knee while on a Hollow operation..." | During combat, Hollow Thug - Poacher tends to harass targets at a distance using 3-shot bursts. |
| Assaulter | Thugs | As the vanguards in Hollow Raider gangs, Assaulters and Ambushers often brandish their weapons and charge ahead independently. This isn't because of their recklessness or disregard for teamwork, but rather a precautionary measure to prevent accidental harm. The modified transformer coils in their hands release high-voltage currents upon contact, capable of paralyzing or even knocking out an opponent with just a touch. And in the logistically difficult Hollows, an incapacitated teammate could pose a terrible challenge for an entire squad. "What's this? Lemme check it out! Oh, it's some electric baton replicaaaa... Aaaaaaaaaaarrghhh..." | During combat, Hollow Thug - Assaulter launches continual spinning assaults, but this crazy suicidal attack often reveals a weakness after. |
 Mutant Formicarrier | Corrupted | Originally a standard-issue Supplies Storage Crate, this unit was equipped with a high-spec electronic anti-theft system capable of thwarting thieves even without external power. A group of smugglers once managed to intercept a shipment, only to discover they couldn't bypass its security permissions. After exhausting every option, they abandoned the crate in a Hollow. To everyone's surprise, several Formicarriers eventually merged with it, transforming it into a mobile nest and taking up residence inside like Hermit Crabs. Veteran Hollow Raiders know the secret to opening it: don't bother hacking the lock, just beat up the Formicarriers living inside first. The incident serves as yet another confirmation of a famous observation by a certain thinker: destruction comes from being broken from the outside, while renewal comes from being broken from within. At least, that's certainly true for this particular crate. "Hold on... you're telling me my cargo, and my Dennies, grew legs and walked off?!" | During combat, the timid Mutant Formicarrier hides inside treasure chests. If anyone tries to take its loot, it will... run for its life. |
 Golden Bangboo | Special | Every Hollow Raider believes there are infinite opportunities in the Hollows that can make you rich overnight. At the heart of every tale of extraordinary wealth is always mention of a special entity known as the Golden Bangboo. According to research conducted by the HIA, numerous Bangboo Wanderers inhabit the Hollows. They diligently gather scattered Gear Coins and Dennies, entrusting them to the Golden Bangboo for safekeeping. While their motives remain a mystery, one thing is certain: These wandering Bangboo, with their peculiar "Ehn-ne" sound diligently fill the pockets of the Golden Bangboo with bags overflowing with Gear Coins and Dennies. As a result, the Golden Bangboo always finds themselves coveted by greedy groups of Hollow Raiders... "N—Nicole!? Look there, a Golden Bangboo!" "What are you waiting for? Smash it to bits! It'll make us rich!" | During combat, Golden Bangboo will sometimes counterattack, too. |
 Airspace Patrolboo | Special | A light Recon Mech of the Airspace Patrol Bangboo Guard Forces. Built for speed, it excels at patrol and scouting missions, while its arm-mounted autocannon provides enough firepower to drive off hostile targets. Its lightweight armor keeps it fast, but offers little protection during high-speed maneuvers. As a result, Recon Mech pilots are all skilled racers. "Only Bangboo without talent need airbags!" | During combat, the Airspace Patrolboo engages targets with its arm-mounted cannon and homing missiles fired from its overhead launcher. |
 Ahriman | Ether Mutants | Due to its unique and grotesque shape, Ahriman is often mistaken for an art sculpture in the Ballet Twins. As a result, many novice investigators are left with lifelong trauma when they first encounter an Ahriman... You just passed by a certain "sculpture" when it suddenly moves... And that fearful moment frozen in place is the perfect moment for Ahriman to launch a surprise attack. "Corin, don't be fooled by how it looks... It's no fancy art." "Now, let's clean it up." | During combat, Ahriman unleashes teleporting assaults and sometimes even teams up with another Ahriman to launch coordinated attacks. |
 Specter | Ether Mutants | Influenced by the distinctive decor of the interior of the Ballet Twins, Specters have the grotesque and twisted limb configuration of an artistic sculpture. Some investigators believe its unique shape is intended to enhance the protection of its Ether Core. Others argue it's merely a trick designed to distract its enemies. While its enemies are mesmerized by its peculiar posture, a Specter will seize the opportunity to launch long-range attacks using concentrated Ether. "I looked at its bizarre structure and thought to myself: Was it trying to play a game of bowling with its own head?" "But before I could make sense of anything, its bowling ball had already smashed into my face..." | During combat, Specter unleashes a burst of ranged attacks in quick succession. |
 Beholder Engine | Ether Mutants | While a Beholder Engine is primarily considered a close-range threat, it frequently presents unforeseen dangers to investigators during Hollow expeditions. Even seasoned investigators can experience an overwhelming sense of panic when confronted by the piercing gaze of its eyes in the darkness. Within the Hollows, fear has a tendency to intensify Ether corruption, thereby inviting calamity. "The only way to overcome fear... is to stare into it and fight it back." | During combat, Beholder Engine moves around by rolling its unique body. |
 Fossor | Ether Mutants | Recent studies by the Whitestar Institute reveal that some Ethereals' limbs carry notable features from their environment. Fossor is a prime example of this — its strange forelimbs bear a striking resemblance to the drilling equipment found in the Old Oil Field region. Although some suggest this is a camouflage tactic to deceive enemies, others have pointed out that Fossor's combat style is aggressive and direct, making it appear ill-suited for ambushes. Some imaginative Hollow Raiders speculate it may have developed this form just to dig for minerals... "When I caught sight of it from a distance, it seemed to be happily digging up the asphalt." "When it spotted me, it didn't hesitate to charge straight at me, desperately trying to drive me away..." "But I was just passing by! I had absolutely no intention of taking any of its junk!" | During combat, Fossor performs consecutive double-handed slashes. |
 Sordidus | Ether Mutants | The Hollows of the Outer Ring are home to a variety of bizarre Ethereals, and Sordidus is a prime example. They possess a unique body structure, with highly flexible limbs that seem to be the result of an unknown reaction between crude oil and active Ether. Once they lock onto a target, they use their limbs like expert acrobats, launching aggressive and brutal attacks. "Damn it... That thing actually whipped me!" "Does it see itself as a tamer, treating us like wild beasts?" | During combat, Sordidus will whip with its tentacles for close-range attacks or insert its tentacles into the ground for long-range surprise attacks. |
 Miasma Spawn | Special | These monsters, still vaguely humanoid after being injected with the Sacrifice serum, have their forms partially restrained by Porcelume — but the grotesque distortions on their bodies remain hard to look at. Lab reports from the Hollow Investigative Association indicate that once the Porcelume is stripped from their bodies, these pitiful humanoids instantly lose control, rapidly deteriorating into more horrifying forms. Despite their seemingly sluggish movements, the Association strongly discourages any attempt to approach or "rescue" them, unless you're capable of taking them out in one blow before they go berserk. "Look at those lumps bulging from their backs, like eternal baggage they can never shed... They're like some kind of evil backpackers, always ready to embark on another journey." | During combat, the Miasma Spawn will summon dust around the player that will explode after some time. Getting out of the dust quickly is your best tactical move. |
 Miasmic Trooper - Shieldguard | Corrupted | An Ethereal Soldier formed from Miasma, wielding a massive, corruptive Miasma blade and protected by an almost impenetrable defense shield, instinctively covers other Miasmic Troopers as they advance. Their immense physical mass and extensive defensive reach make them formidable in positional warfare, especially in groups, where they become significantly harder to handle. The Hollow Investigative Association advises swiftly eliminating any isolated units on sight. "An Ethereal whose main role is to protect others? Now that's a rare sight..." "Don't overestimate the Ethereals. Remember, whatever's behind these things was never human to begin with!" | During combat, Miasmic Trooper - Shieldguard uses its shield to both significantly reduce DMG and Daze taken, and also counterattack. |
 Miasmic Trooper - Cannoneer | Corrupted | The Ethereal soldiers, formed from Miasma, wear tattered old uniforms and linger in the smoke of battle like ghosts from another era. Hollow observation data shows that the Canonneers can strike nearby targets with impressive precision using their bazookas — a level of accuracy suggesting rigorous training, which has sparked much speculation. "Could these newly discovered, highly organized Ethereal units be linked to the Defense Force?" "Sorry. No comment until the matter is fully investigated and confirmed." | In combat, the Miasmic Trooper - Cannoneer prefers to provide heavy firepower support from a distance. Additionally, some of its skills inflict potent Miasma Corruption. |
 Special Anti-Riotboo | Special | A standard frontline unit of the Airspace Patrol Bangboo Guard Forces. Its agile mechanical arms and high-powered chainsaw make it highly effective against Ethereals and allow it to assist with the maintenance and repair of heavy machinery, earning praise from both Airspace Patrol personnel and Energy Hub engineers. That versatility comes at a price. Its open cockpit design and limited combat range leave pilots exposed to greater danger on the battlefield, so only the most courageous Bangboo are trusted to operate it. "Strong left arm, stronger right arm!" | During combat, the Special Anti-Riotboo can unleash a series of consecutive melee attacks. Use Defensive Assist before it strikes to interrupt its assault. |
 Kulullu | Ether Mutants | With its grotesque and unsettling appearance, Kulullu has topped Booastrum's "Factors Affecting Children's Nighttime Security" list for several years in a row. Yet despite that nightmarish visage, its attacks are surprisingly simple and slow, almost as if it posed no real threat... or do they? The truth is, a single strike is enough to knock someone out for days. Over time, many investigators have come to refer to it with equal parts fear and respect: "One-Slap Wonder." Perhaps Kulullu understands the essence of martial arts better than anyone: concentrate all your power into a single strike, and perfect it. "Ever been hit by a slap the size of a sandbag?" | In combat, Kulullu will use ranged attacks and rush attacks after a charge. Stay sharp and dodge them when you see them coming. |
 Metamorphosed - Beholder Engine | Ether Mutants | One who sheds a shattered shell in darkness, reborn through corruption, having forsaken its fallen form. Although the Beholder Engine is classified in the Hollow Investigative Association's archives as an Ethereal that only poses a certain level of threat at close range, it frequently presents unforeseen dangers to investigators during Hollow expeditions. Even seasoned investigators can experience an overwhelming sense of panic when confronted by the piercing gaze of its eyes in the darkness. Within the Hollows, fear has a tendency to intensify Ether corruption, thereby inviting calamity. "The only way to overcome fear... is to stare into it and fight it back." | During combat, the Metamorphosed - Beholder Engine fires laser beams from its eye and attacks with its spherical body. |
 Metamorphosed - Airspace Patrolboo | Special | A rebel that sheds its old shell in the gloom, emerging anew amidst corruption, forsaking the body that once sank into depravity. A light Recon Mech of the Airspace Patrol Bangboo Guard Forces. Blue markings on the chassis indicate assignment to Hollow operations. Built for speed, it excels at patrol and scouting missions, while its arm-mounted autocannon provides enough firepower to drive off hostile targets. Its lightweight armor keeps it fast, but offers little protection during high-speed maneuvers. As a result, Recon Mech pilots are all skilled racers. "Only Bangboo without talent need airbags!" | During combat, the Metamorphosed - Airspace Patrolboo engages targets with its arm-mounted cannon and homing missiles fired from its overhead launcher. |
 Metamorphosed - Special Anti-Riotboo | Special | A rebel that sheds its old shell in the gloom, emerging anew amidst corruption, forsaking the body that once sank into depravity. A standard frontline unit of the Airspace Patrol Bangboo Guard Forces. Blue markings on the chassis indicate assignment to Hollow operations. Its agile mechanical arms and high-powered chainsaw make it highly effective against Ethereals and allow it to assist with the maintenance and repair of heavy machinery, earning praise from both Airspace Patrol personnel and Energy Hub engineers. That versatility comes at a price. Its open cockpit design and limited combat range leave pilots exposed to greater danger on the battlefield, so only the most courageous Bangboo are trusted to operate it. "Strong left arm, stronger right arm!" | During combat, the Metamorphosed - Special Anti-Riotboo can unleash a series of consecutive melee attacks. Use Defensive Assist before it strikes to interrupt its assault. |
 Air Patrol Vanguard | Special | In combat, the Aerial Vanguard responds to teammates' commands to launch follow-up attacks. | |
 Sky Patrol Lancer | Special | The vanguard of Roscaelifer's Airspace Patrol, equipped with standard-issue greatswords forged from Porcelloy. The blades possess excellent Ether conductivity, capable of resonating with Ether to channel Energy into the cutting edge and further enhance the weapon's lethality. The Airspace Patrol's enforcement units are renowned for their strict discipline and operational efficiency. Patrol members come from all walks of life, but front-line commanders at the rank of lieutenant and above are predominantly drawn from a storied noble house—the de L'Azur family. The family holds no hereditary claim to military rank; their current standing owes more to a longstanding tradition of training their children in Tactics from an early age. Most of the younger generation see joining the patrol as a natural rite of passage, and to be born a de L'Azur means you must be an irreproachable standard-bearer among them. "Don't you think this sword is... a little too heavy?" "Huh?! So you feel that way too—I thought I just wasn't strong enough. I never dared say anything..." | In combat, the Aerial Patrol Gunlancer commands nearby Aerial Patrol Vanguards and Aerial Patrol Guards to launch a Coordinated Attack. |
 Sky Patrol Guard | Special | Guards of the Roscaelifer Airspace Patrol Department, clad in standard-issue gear crafted by the Flint family, tasked with maintaining the city's daily order. The Airspace Patrol's patrol divisions are renowned for their ironclad discipline and razor-sharp efficiency. Members of the Airspace Patrol come from all walks of life, but most ground-level commanders at the rank of lieutenant and above hail from a distinguished old bloodline—the de L'Azur family. The family holds no hereditary claim to military rank; their standing today stems largely from a long-standing tradition of training their young in the art of Tactics from an early age. Most of the younger generation see joining the patrol as a natural rite of passage, but to be born a de L'Azur is to be held to an unimpeachable standard. "You call that fighting? You think those flashy moves are gonna cut it against Lady Sigrid? Go hit the training grounds and come back when you're actually ready." | In combat, Sky Patrol Guards respond to teammates' commands to perform follow-up attacks. |
 Special Offensive: Grenadier Jaeger | Rebel Soldiers | During combat, Special Offensive Grenadier Jaeger provides heavy ranged fire support. | |
 Special Offensive · Light Jaeger | Rebel Soldiers | During combat, Special Offensive Light Jaeger will provide continual fire support. | |
 Special Offensive: Strike Jaeger | Rebel Soldiers | During combat, Special Offensive Strike Jaeger slides to get close to targets or tosses out knives with delayed explosions. | |
 Special Offensive · Guard Jaeger | Rebel Soldiers | During combat, Special Offensive Guard Jaeger uses its shield to both significantly reduce DMG and Daze taken, and also counterattack. | |
 Farbauti | Ether Mutants | Farbauti, possessing immense strength and often in a frenzied state, is one of the most formidable threats Hollow Raiders may face. Its hammer-like arms can effortlessly deflect damage and unleash storms of blows that crush everything in its path. Some Hollow Raiders have observed Farbauti frequently pounding the ground in a rhythmic, high-frequency manner, leading to speculation about its peculiar interest in drumming music. Despite the Hollow Investigative Association publicly debunking this rumor, many Hollow Raiders carry portable stereos in an attempt to distract Farbauti with music. No successful escapes using this method have been reported however. "The reason for their failure is simple: Even Farbauti think your taste in music sucks!" | During combat, Farbauti uses its powerful arms to launch continual hammer attacks but those same arms can take damage and become Staggered with enough hits. |
 Hati | Ether Mutants | The HIA Phase-I Investigation Team has officially documented the existence of this sentient living Ether resembling a four-legged beast, which poses significant danger. According to rumors, the first sighting took place in Nest Hollow, where individuals exploring the nearby wastes reported hearing ear-splitting roars reminiscent of wild animal growls. "If I throw a stick or a ball, do you think that monster will catch it?" "You can give it a try, but I won't cover your medical bill." | During combat, Hati uses nimble leaps and quick claw attacks. |
 Goblin | Ether Mutants | During initial encounters with these unique Ethereals, Hollow investigators mistakenly thought they possessed some level of intelligence, even showing signs of learning to wield bludgeoning weapons like humans. As a result, they were dubbed "Goblins." However, subsequent research revealed that their "hammers" were actually twisted and deformed limbs, and that they lacked the ability to imitate human behavior. Nevertheless, Goblins remain formidable adversaries due to their robust physique and sheer brute strength, with even a simple swing of their limbs proving deadly. If anything trespasses on their territory, they will immediately enter a state of fury, sparing no effort in mercilessly smashing the intruder. "Huh? There's a Goblin running over here, banging on a heap of scrap metal." "Don't you think his attacks have a rhythm to them, like he's playing a drum...?" "Hey! Don't be stupid, you two! That's not scrap metal! It's our supply truck!" | During combat, Goblin's roar boosts its DMG dealt while significantly reducing DMG taken. However, these effects are interrupted if Stunned. |
 Armored Hati | Ether Mutants | The Armored Hati is widely regarded as a formidable adversary by many experienced Hollow investigators. Although its armored shell limits its agility, it compensates with exceptional resistance to attacks. Additionally, the corrupted material on its body forms sharp and hardened protrusions that can cause additional damage when an Armored Hati charges at high speeds. This creature's agile movements, resilience to blows, and seamless armor compel even the most seasoned explorers to seek alternative routes to avoid direct confrontation. Some novice Hollow Raiders have attempted to lure Armored Hati away with pet food. However, these endeavors have proven futile. "Run! It doesn't like this flavor of dog food!" | During combat, Armored Hati's armor significantly reduces DMG and Daze taken, but Defensive Assist greatly reduces its armor. |
 Metro Goblin | Ether Mutants | The debate regarding Metro Goblin is a persistent one. Some scholars argue their peculiar appearance serves as camouflage to confuse their enemies, while others attribute the debris on their bodies to corruption and fusion with old metro equipment. Nevertheless, the presence of Metro Goblins evokes fear among inexperienced investigators exploring the Hollow's old metro zone. At any given moment, an ordinary-looking "road sign" may start trembling, and then a formidable Ethereal emerges from the ground, charging menacingly. "Huh? I saw this sign a few minutes ago. Have we been going in circles?" "No... That 'road sign' has been following us!" | During combat, Goblin's roar boosts its DMG dealt while significantly reducing DMG taken. However, these effects are interrupted if Stunned. |
 Arlaune | Ether Mutants | Many novice Hollow Raiders who come across an Arlaune for the first time are often deceived by its appearance, mistakenly assuming it to be a harmless plant. However, upon approaching it, they discover that Arlaune release a concentrated discharge of Ether matter, catching their unsuspecting victims off guard. "Huh? I tried to water it, and it spat at me?" | During combat, Arlaune is extremely cunning at launching ranged attacks from a distance. However, Staggering it when its petals are wide open will build up a lot of Daze in just one shot. |
 Autonomous Support Unit - Sweeper | Public Security | An automatic combat mech utilized by Public Security. It possesses various combat modes tailored to various Ethereals types. Its weapons include circular chainsaws and fusion heat rays. Sweepers can swiftly identify target Ethereals and adapt to the most effective combat strategy. However, their reliability diminishes to some extent when faced with Hollow Raiders who possess greater versatility than Ethereals. "Stirring, chopping, heating... I wonder who came up with this? Maybe some undercover agent from a kitchenware company trying to boost sales?" | During combat, Autonomous Support Unit - Sweeper uses its long arms to perform a spinning attack. Use Defensive Assist before it does so to completely prevent it from even executing the skill. |
| Heavy Striker | Rebel Soldiers | An automatic tactical mech of the Defense Force, providing continuous fire support for front-line personnel. Its inert Ether shield can withstand most light firepower and even impacts from large-sized Ethereals. Undoubtedly, it is one of the most trusted "companions" of the Defense Force. "Remember, if you're in trouble, just stay behind them... You'll be pretty safe unless they accidentally squish you." | During combat, Heavy Striker deploys a shield. While shielded, it will only accumulate Fire and Physical Anomaly Buildup. Inflict Burn, Assault, or Stun it to break the shield. |
| Lightfoot Rover | Rebel Soldiers | The Lightfoot Rover, a mainstream fire-support mech in the Defense Force, is equipped with tactical algorithms that analyze the opponent's behavior and calculate trajectories for precise targeting. When it identifies a high-threat target, it deploys a swarm of drones from its arsenal, unleashing immense firepower. For Hollow Raiders, the sudden appearance of a Lightfoot Rover can spell trouble... endless trouble... "What the! It... it even has kids!?" | During combat, Lightfoot Rover summons two drones to fight in tandem, which can be piloted nearby a target to launch a self-destruct attack. |
 Heavy Gunner | Rebel Soldiers | A heavy infantry unit belonging to the New Eridu Defense Force. Equipped with "Gray Rhino" heavy combat armor paired with a complete arsenal enhanced using Ether technology, they can sustain high-intensity firepower for an extended period when ample ammunition is available. They serve as the assault core of a combat team and are often deployed as the front line in assault and clearance operations. After the fall of the old capital, many soldiers left the army and joined civilian factions. Since then, these elite gunners have emerged under various banners, including private armies of plutocrats, new security companies, and even roving gangs of bandits... "I'm convinced those heavy gunners are secretly adorable little girls who somehow manage to hide all that ammo in the extra pockets of their combat suits. I mean, how else can you explain their endless stockpile of shells?" | During combat, Heavy Gunner switches between using laser cannons and frag grenades to perform continual long-range attacks. |
 Tarasque Mixer | Ether Mutants | Based on their research, the Hollow Investigative Association speculates the Tarasque Mixer contains various levels of liquefied Ether. When it stirs and mixes its stored Ether, a complex reaction takes place, resulting in the release of destructive and violent energy. The power unleashed is comparable to that of the heavy artillery employed by the Defense Force. Experienced investigators understand the importance of maintaining a low profile to avoid direct bombardment from its heavy artillery. "When it leaned down towards me, I thought it was some kind of strange welcoming gift. But when its cannon chamber lit up, I realized... it was a farewell gift." | During combat, Tarasque Mixer uses continual laser attacks while making sideways jumps to reposition. |
| Miasmic - Huskron | Corrupted | A fallen creation, reshaped in the depths of impure darkness. To step into the domain of the sleeping behemoth is to prepare for confronting the crimson nightmare, for it's no longer content with games of hide and seek. The reckless Hollow Raider attempts to provoke, luring it to expose its deeply buried core. Yet skilled hunters often appear as prey - letting your guard down when the enemy's weakness is revealed is often a rookie's deadliest flaw. "Don't call me stupid, my head really was caught in those Ethereal pincers..." | During combat, Miasma Ravager - Huskron, corrupted by Miasma, now possesses enhanced physique and a more vicious assault pattern. Using a Defensive Assist at the right moment can counter its brutal offense. |
| Bulky Intimidator | Thugs | In contrast to fully equipped Hollow investigators, Bulky Intimidators and Wanted Intimidators possess minimalistic gear. Nevertheless, these notorious thugs can easily instill fear in their victims with their makeshift equipment. A spiked metal bat and a modified double-barreled shotgun are all they need to establish themselves as the most feared brutes in the Hollow. According to investigators who have encountered them in the Hollows, these brutes enter an extreme state of euphoria during battle. Their "demeanor" could hardly be called combat suitable, and more closely resembles bullying. "Fighting them brought back the fear I felt when facing the school bullies alone..." | During combat, Hollow Thug - Bulky Intimidator switches between using a club and a shotgun for nearby attacks while sometimes kicking up sand to launch an ambush. |
 Miasmic - Lightfoot Rover | Corrupted | Once a standard fire-support mech, now corrupted within the Hollow. It's tactical algorithms now in total disarray, flagging every lifeform it sees as a high-threat target and firing indiscriminately. Built for offense over defense, it boasts exceptional mobility, making it hard to hit and relentless in pursuit. If you're unlucky enough to be tagged by it, pray there's a spatial rift nearby — without one, escape is nearly impossible. "If I could go back to middle school, I'd never slack off in track practice again." | In combat, Miasmic - Lightfoot Rover summons two drones to assist in battle. If Miasmic - Heavy Striker is also on the field, Miasmic - Lightfoot Rover will coordinate attacks together with it. Additionally, when Miasmic - Heavy Striker is close to death, Miasmic - Lightfoot Rover will leap toward the target due to coordinated combat signal interference, seize its combat data core, gain part of Miasmic - Heavy Striker's shield components and abilities, and trigger a small Miasmic Field. |
| Bulky Enforcer | Thugs | There is a consensus within the New Eridu underworld that the most formidable fighters are not the champions of the ring, but rather the Bulky Enforcers and Wanted Enforcers lurking in the depths of the Hollow. These professional thugs are hired by Ether thieves at high prices to protect their illegally excavated Ether resources. Being ardent boxing enthusiasts, Bulky Enforcers have modified high-voltage stun guns into boxing gloves, augmenting the destructive power of their punches. To them, Ethereals, Hollow Raiders, Hollow investigators, and even scattered members of Public Security... are not seen as opponents but merely as "training sandbags" for their personal amusement. "Wait a minute! I think I've seen this guy's fighting stance in the arcade on Fourth Street!" | During combat, Hollow Thug - Bulky Enforcer uses both fists to punch while using nimble sidesteps to shake up the angle of attack. |
 Miasmic - Heavy Striker | Corrupted | This autonomous tactical mech, swallowed by the Hollow, has grown even more brutal after corruption, powerful enough to crush Goblins with ease. Once a steadfast shield protecting soldiers against devastating attacks, the Defense Force's most trusted companion has now transformed into a terrifying killing machine. "If you have the courage, then grant our once-reliable friend a final end, freeing it from the sins and shattered honor it now carries." | In combat, when Miasmic - Heavy Striker deploys its shield, it activates a small Miasmic Field. If Miasmic - Lightfoot Rover is also on the field, the two will carry out coordinated attacks. Additionally, when Miasmic - Lightfoot Rover is close to death, Miasmic - Heavy Striker will leap toward the target due to coordinated combat signal interference, seize its combat data core, acquire Miasmic - Lightfoot Rover's drones and abilities, and command the drones to fight alongside it. |
 City Guardboo | Special | An elite combat unit fielded by the Roscaelifer Airspace Patrol. Originally deployed to guard critical infrastructure, it was driven out of control by the effects of a Singularity Leakage and Hollow activity. It now wreaks havoc throughout the lower levels of the floating island and within nearby Hollows. City Guardboo forms the backbone of Roscaelifer's Bangboo Guard Forces, serving in assault, air defense, and facility security roles. To support these missions, it is equipped with heavy air-to-ground weaponry. Although the exoskeletal mech has been compromised by Ether Corruption, the Bangboo pilot inside remains fully operational, lying dormant while waiting for a chance to break free. "Ehn-ne, ehn-ne-ne! (I wanted to become a Guardboo! Commander Norma was so happy she even gave me my favorite Ether batteries!)" | During combat, City Guardboo alternates between close-range combos and ranged attacks and will also launch charging attacks. Using a Defensive Assist at the right moment can counter its offense. |
| Enraged Sweeper | Thugs | A significant number of combat mechs belonging to Public Security are destroyed within Hollow each year. Some of these mechs are subsequently repaired by Hollow thugs and illegally modified into Enraged Sweepers. Despite lacking access to standard parts or professional repair services, the thugs manage to restore these mechs using makeshift components, striving to maintain their original combat capabilities. In their pursuit of individuality, the thugs often apply custom paint jobs and even install high-powered loudspeakers on their Enraged Sweepers. While this does not enhance their combat effectiveness, it does make them seem cooler than the originals. "Here we go! There's an easy prey with pink hair over there!" "Yo! Switch to the background music we always use for robberies!" | During combat, Illegal Support Unit - Enraged Sweeper uses its long arms to perform a spinning attack. Use Defensive Assist before it does so to completely prevent it from even launching. |
 Hornet | Ether Mutants | Hornets always seem to be buzzing around Nineveh. Some scholars believe that the two have formed a symbiotic relationship and that, in some respects, they have reached a kind of group coordination. As Nineveh's energy increases, revealing its distinctive swaying blossom stance, the Hornets enter a frenzied state and try their best to attack any moving target nearby. "Hey! Something just flew out of that 'flower'!" "Looks like... a swarm of wasps?" | In battle, Hornets will assist Nineveh by distrupting and attacking enemies. |
 Mors | Thugs | Mors was once the most feared bounty hunter in the Outer Ring. He possessed an almost obsessive desire to hunt, often tracking his targets relentlessly day in and day out. Once he had a target in his sights, he would obsessively pursue the kill until his prey was dead. "Lone Wolf Mors" never fails — this is the belief held by all major factions in the Outer Ring. However, during one "hunt," Mors pursued his target day and night for three days... Yet, even after exhausting his strength, he still failed to kill the target. Surprisingly, the man named Pompey didn't take it personally and instead offered an invitation to the defeated Mors — asking him to join his own organization. From that point on, the infamous "hunter" Mors was nowhere to be found. However, within The Vanquishers, a new figure emerged — a silent, solitary captain. Even now, Mors remains elusive, often disappearing for long periods. He only resurfaces when faced with a foe who genuinely intrigues him, not out of duty as a captain, but simply to indulge in the thrill of combat and the sheer joy of the hunt. "You want to challenge Captain Mors to a duel? Heh, do you really think you're up for it?" "Go sign up over there first, then come back next month to try your luck in the draw." | During combat, Mors adapts to the battlefield, switching between close-range combos and long-distance shots. When his health drops below a certain percentage or after a set period, he'll start using follow-up long-range attacks or ambush targets with blind spot shots after quickly repositioning. |
 Pulchra | Thugs | No one knows where Pulchra came from, but she was once one of the top mercenaries of the Outer Ring, a "chameleon" who was adept at adapting depending on the situation. Not long after the previous Tour de Inferno ended with Pompey's consecutive victory, a few factions conspired in the shadows to launch a surprise attack on The Vanquishers. This scheme was easily dealt with by The Vanquishers, as if all their plans were within The Vanquishers' grasp. The losers were chased out of the Old Oil Field, yet Pulchra, who had allied with them, was completely untouched. Naturally, many believed that this victory relied on a betrayal. Though many made offers, hoping she'd join them, Pulchra never officially joined any gang. Perhaps, to her, all these conspiracies and conflicts within the Outer Ring were just a game she could quit at any time. Even if her employer was loathsome, she wouldn't care, so long as they had the money and the job was interesting. Especially if the job involved luring an enemy into an exquisitely prepared trap, allowing her to watch them slowly descend into the abyss of death... Luring, deceiving into complete destruction... The more beautiful, the more deadly, that has always been her code of survival. "What, you wanna work under big sis Pulchra?" "Heh, another poor sucker..." | During combat, Pulchra maintains distance, waiting for the right moment to use physical attacks, her bladeguns, and gadgets to disrupt the target. When her health drops below a certain percentage, she drinks a tonic to enhance her ability to dodge, allowing her to dodge all attacks from nearby targets. |
 Bellum | Thugs | As an arena champion with an impressive win streak, Bellum once called himself the number-one fighter in the Outer Ring... Until his win streak was ended. What was even more infuriating... was that arrogant guy didn't even remember his name. Angry, Bellum honed his fighting skills, swearing that he would make his name known throughout the Outer Ring once more and make the arrogant jerk who beat him pay. To achieve his goal, Bellum joined The Vanquishers and helped Pompey defeat enemy after dangerous enemy. He could skillfully modify and operate a flamethrower, leading the charge to incinerate enemies in his path. He could also command his squad with seamless precision, organizing them into an unstoppable battle force. Every battle he led ended in victory. Now, Bellum no longer needs to make a name for himself. Though he's no longer that champion with an impressive win streak, in the Outer Ring, everyone knows the terror of gang wars, and as a member of The Vanquishers' core fighting force, Bellum was war itself. "You don't wanna do menial jobs? Heh, you can complain about that once you defeat boss Bellum!" "Now go clean the toilet!" | During combat, Bellum uses his bladegun, shield, and flamethrower to pressure the enemy at close range. If Bellum is attacked while guarding with his shield, he'll respond with a powerful counterstrike. When his health drops below a certain percentage, Bellum's attacks intensify, becoming even more vicious and relentless. |
 Miasmic - Frenzied Maniac | Corrupted | A fallen creation, reshaped in profound darkness and impurity. Unfortunate souls mutated by the intense corruption of Etheric matter within the Hollows. Due to a considerable degree of Ether aptitude and physical capability, their bodies have not been completely transformed by the Ether, retaining humanoid features but with enhanced mutant limbs that are more dangerous. Judging from the remnants of clothing and combat experience, likely once a senior gang member or Raider lurking in the Hollows. These corrupted subjects, potentially due to their enhanced physiology or affinity for Ether matter, have developed formidable close combat abilities, making them even more menacing than the typical monsters found in the Hollow. "Their weapons look very fancy... and kinda like they came as freebies." | In combat, the Miasmic - Frenzied Maniac uses its stealth specialty to launch surprise attacks. When paired with Miasmic - Trinox, it will perform a Perfect Dodge against player attacks, followed by a Coordinated Attack with Miasmic - Trinox. Additionally, when one of them dies, the survivor will enter Frenzy. |
 Miasmic - Trinox | Corrupted | A fallen creation, reshaped in profound darkness and impurity. The Hollow Investigative Association has been studying the mutation characteristics of Ethereal humanoid bodies. Trinox has consistently ranked in the top three of research popularity lists due to its seemingly deliberately designed triangular head structure. There were even rumors of mathematicians disguising themselves as investigators to infiltrate the Hollow just to witness Trinox firsthand. The latest research results were published in "Hollow Encyclopedia" Issue 28, February Edition. According to subscribers, the article only discussed the aesthetic significance of Trinox's head structure. Dissatisfied Hollow-related readers gave the article the lowest score of the issue on the magazine's website, with only a 34% approval rating currently. "Trinox's head measurements are close to the ancient golden ratio!" "We're fighting the Ethereal, not hosting a beauty pageant for them, Professor." | In combat, Miasmic - Trinox uses parry mechanics to deflect DMG and unleash Block Counter. When Miasmic - Frenzied Maniac is present on the field, Miasmic - Trinox will command it to perform a Coordinated Attack together. Additionally, when one of them dies, the survivor will enter Frenzy. |
| Security Enforcer | Special | This civilian-grade Tactical Security Unit, replicated by Typhoeus Security based on Public Security's Search Patrollers, has been modified in both firepower and technology to avoid potential technical reviews and copyright infringement claims. However, these modifications haven't diminished the combat capabilities of these security devices. Without budget constraints on manufacturing, Typhoeus Security used higher-grade but more expensive materials, significantly enhancing their usability and durability. These devices became highly sought after by many commercial companies as soon as they hit the market. "Hello, Security Enforcer at your service. Please select your desired patrol mode..." "Uh... you're saying it has over a hundred preset modes?!" | In combat, Tactical Security Unit - Security Enforcer uses its shield to both significantly reduce DMG and Daze taken, and also counterattack. |
| Light Patroller | Special | A mass-produced security unit made by Typhoeus Security, put into use across many civilian sectors. With numerous advantages, including affordability, versatility, a revolutionary single-wheel dynamic balance system, and an integrated intelligent threat recognition core, they're suitable for security needs in various complex spaces. "This Tactical Security Unit, having passed 47 rigorous tests, has been successfully deployed in core areas of 32 industrial parks. Client feedback shows an average 91% reduction in tresspassing rates. Trust us: you can use it for any security task you can imagine." | In combat, Tactical Security Unit - Light Patroller performs a dash attack using the chainsaws mounted on its arms. |
| Medium Patroller | Special | A mass-produced security unit manufactured by Typhoeus Security, modified from Public Security's support combat mechs. Compared to the support combat mechs, some combat capabilities have been reduced, mainly relying on its large shield to suppress low-threat groups like rioters, maintaining order and guiding crowds during large events and special occasions. According to reports, some units were purchased and modified by illegal operators to create the Illegal Support Unit "Enraged Sweeper." Some even went as far as posting reviews on the company's official website saying "This quality is worse than the scrapped support mechs I picked up in the Hollow!" and giving the product a one-star rating. "These illegal modifications have nothing to do with our security company and are private modifications by users. We will fight to the end against such negative reviews... I mean, illegal activities..." | In combat, Tactical Security Unit - Medium Patroller uses its long arms to perform a spinning attack. Use Defensive Assist before it attacks to completely prevent it from executing the skill. |
 Miasmic - Wicked Wraith | Corrupted | A fallen being, reforged within the depths of corruption and shadow. Its most striking feature lies in its grotesquely developed arms, the embodiment of the Wicked Wraith's fury. The limbs themselves are bulkier than a standard double-door refrigerator, coated in dense keratin layers that interlock to form a natural hammer shape. One expert from the Hollow Investigative Association claimed such abnormal development may stem from the host's original body having long relied on heavy machinery or strength-enhancing equipment, causing its physical traits to become grotesquely amplified during the corruption process. Reports indicate it can smash through reinforced concrete and fling the remains of derelict vehicles several dozen meters. Among investigators, it's colloquially known as the "Hollow Demolition Crew." One account tells of a Wicked Wraith that, in its fury, leveled a whole ruin in under a minute, only to get stuck in a tight corridor, its massive frame unable to keep balance, and was later retrieved as a research specimen. "When it slams the ground, even the echoes throughout the Hollow tremble... but if you're quick enough, maybe you won't have to arm-wrestle it." | Miasmic - Wicked Wraith attacks with a giant axe and shotgun. Its axe attacks can create Miasma Pools on the ground, and these attacks can inflict an Miasma Corruption effect on players. |
 Ionized - Pugnus | Ether Mutants | Not all Ionized beings within the Hollows prefer to hide, and Pugnus wears its menace on every sharpened spike. Clad in armor, its back and tail bristle with razor spines, while its massive pincers serve not only as weapons but as war drums that pound the earth to mark its territory. Pugnus tends to build power from within the shadows, yet can suddenly spring forth — bringing its full weight down with both crushing claws upon its prey. Its shockwaves are powerful enough to throw inexperienced fighters off balance, and the flying debris that follows often seals off any escape routes. Its attack rhythm suggests it relies on ground vibrations to track its prey before lunging in a sudden, explosive strike to finish the fight. Interestingly, some Hollow Raiders who've spent years dealing with Pugnus have developed a unique "Lightfoot Hollow Step" technique: "I used to get knocked off balance by its tremors, but then I learned to step on my toes and move quickly... Now I'm somehow winning stilts racing competitions at festivals." | In combat, Ionized - Pugnus tends to unleash continuous hammer attacks with its powerful arms, combining attacks with the spikes on its head and tail. When Ionized - Pugnus slams the ground, it also creates a large area attack. |
 Lahmu | Ether Mutants | According to Airspace Patrol defense reports, Lahmu are among the most common native Ethereals in Roscaelifer. Their razor-sharp claws and exceptional mobility have made them a persistent headache for countless patrol officers. Thanks to posing just the right amount of threat, Lahmu have become the Airspace Patrol's unofficial benchmark for combat capability. Defeating one is considered proof that an officer can hold their own in the field. "Hey, did you hear? They say Commander Sigrid can take down 100 Lahmu single-handedly!" "Then with both hands, that'd be 200! Commander Sigrid is amazing!" "You blockhead, that's not how it works! If Commander Sigrid used both hands... she could probably take down 10,000 Lahmu!" | During combat, Lahmu use their four massive claws for melee attacks, repeatedly crushing any target that gets too close. |
 Mushussu | Ether Mutants | A formidable Ethereal, the Mushussu is known for its relentless charges and hard-to-avoid projectile attacks, making it a dreaded foe among investigators. More war machine than angry serpent, the Mushussu barrels across the battlefield, crushing anything that stands in its way. Only those who have faced it head-on can truly understand how terrifying it is. Rumors persist that Mushussu prey on Bangboo civilians. Despite repeated attempts by the Airspace Patrol to debunk the claim, many Bangboo remain unconvinced. Even when equipped with advanced combat armor, some Bangboo officers still tremble at the sight of a Mushussu, significantly reducing their combat effectiveness. "So why are Bangboo so afraid of Mushussu?" "Don't snakes love eating eggs? And don't Bangboo kind of look like eggs with legs? A snake with legs eating an egg with legs sounds perfectly reasonable to me!" "How is any of that reasonable?!" | During combat, the Mushussu channels Ether energy through its mouth and shoulder cannons to unleash a variety of long-range projectiles. |
 Metamorphosed - Tarasque Mixer | Ether Mutants | One who sheds a shattered shell in darkness, reborn through corruption, having forsaken its fallen form. Based on their research, the Hollow Investigative Association speculates the Tarasque Mixer contains various levels of liquefied Ether. When it stirs and mixes its stored Ether, a complex reaction takes place, resulting in the release of destructive and violent energy. The power unleashed is comparable to that of the heavy artillery employed by the Defense Force. Experienced investigators understand the importance of maintaining a low profile to avoid direct bombardment from its heavy artillery. "When it leaned down towards me, I thought it was some kind of strange welcoming gift. But when its cannon chamber lit up, I realized... it was a farewell gift." | During combat, the Metamorphosed - Tarasque Mixer attacks nearby enemies with its mechanical claws and fires a sustained laser beam at distant targets. |
 Metamorphosed - City Guardboo | Special | A rebel that sheds its old shell in the gloom, emerging anew amidst corruption, forsaking the body that once sank into depravity. An elite combat unit fielded by the Roscaelifer Airspace Patrol. Blue markings on the chassis indicate assignment to Hollow operations. Originally deployed to guard critical infrastructure, it was driven out of control by the effects of a Singularity Leakage and Hollow activity. It now wreaks havoc throughout the lower levels of the floating island and within nearby Hollows. City Guardboo forms the backbone of Roscaelifer's Bangboo Guard Forces, serving in assault, air defense, and facility security roles. To support these missions, it is equipped with heavy air-to-ground weaponry. Although the exoskeletal mech has been compromised by Ether Corruption, the Bangboo pilot inside remains fully operational, lying dormant while waiting for a chance to break free. "Ehn-ne, ehn-ne-ne! (I wanted to become a Guardboo! Commander Norma was so happy she even gave me my favorite Ether batteries!)" | During combat, Metamorphosed - City Guardboo alternates between close-range combos and ranged attacks and will also launch charging attacks. Using a Defensive Assist at the right moment can counter its offense. |
 Special Offensive · "Lightfoot Rover" | Rebel Soldiers | During combat, Special Offensive · "Lightfoot Rover" summons two drones to fight in tandem, which can be piloted nearby a target to launch a self-destruct attack. | |
 Special Offensive·「Heavy Striker」 | Rebel Soldiers | During combat, Special Offensive Heavy Striker deploys a shield. While shielded, it will only accumulate Fire and Electric Anomaly Buildup. Inflict [Burn], [Shock], or Stun it to break the shield. | |
 Dullahan | Ether Mutants | A potent humanoid living Ether, initially observed in the Laketown Hollow and documented by the Third Investigation Team of the Hollow Investigative Association. The exact correlation between these living Ether beings and the downfall of the lakeside town known as Blaise remains uncertain. Due to their immense power and formidable fighting style, the HIA has labeled them as highly dangerous and advises novice investigators avoid direct confrontations with them. "Don't let it activate its sword, and if it already has... just don't get cut." | During combat, Dullahan uses its longsword to charge up and perform a high-level stab, which can be interrupted by your high-level attack. |
 Thanatos | Ether Mutants | Hollow exploration can be mentally distressing, and Thanatos, with its unique teleportation ability and unpredictable attack patterns, has become a common psychological challenge among Hollow Raiders. A considerable number of individuals who have faced Thanatos alone in the Hollow have lost all courage to continue their ventures and instead chosen to retire prematurely. As a result, these elusive entities have become recurring figures in horror movies. "The slender shadow disappears before your eyes and reappears behind you..." "What should I do? Now I'm too scared to even go to the restroom alone..." | During combat, Thanatos blinks around to attack from tricky angles, but its Daze buildup when using Defensive Assist and Assist Follow-Up is also very high. |
| Guardian | Rebel Soldiers | The Defense Force will only dispatch the fully armed mechs known as Guardians during operations in large-scale Hollows. These mechs are equipped with active Ether shock blasters, Ether-charging guns MARS-74, and even fusion heat rays... causing the Guardian to often be referred to as Public Security's mobile arsenal. Despite their formidable firepower, they possess impressive mobility, enabling them to jump and sprint while dispersing groups of lesser Ethereals and advancing the front lines. For Hollow Raiders, encountering a single Guardian is akin to facing an impregnable fortress. "I'll strike in my Fortress Form!" | During combat, Autonomous Support Unit - Guardian not only performs powerful melee attacks, but can also use a variety of ranged attacks. When adjacent to another unit, some Autonomous Support Unit - Guardian units will focus on providing ranged fire support from outside the core battlefield. |
 Lockspring | Special | In the early days of Bangboo's creation, Lady Sunbringer had a grand vision: to create a highly intelligent Bangboo capable of independently judging and executing "protection" commands to help humanity against threats from the Hollows. And "Lockspring," designated GU-0001, was the first creation of this great plan. He was given the most advanced tactical modules, the most powerful fire systems, and... a pure heart programmed with the highest directive to "protect humanity." However, during the hellish disaster of the old capital's fall, he witnessed for the first time the irredeemable darkness lurking in the souls of the humans he was meant to "protect." He saw people betray and slaughter each other for survival, and watched as his trusted users forced him to point his gun at defenseless fellow humans. The noble ideals etched in his core code clashed violently with the ugly reality before him in the most acute and cruel way. At that moment, he finally understood that humanity's greatest enemy was never the monsters from outside— But rather humanity's own endless desires and conflicts. "Humans are truly adorable. Even though you keep making the same mistakes..." "But it's alright, I'll forgive you." "And... I'll help fix everything with my own hands." | In combat, Lockspring attacks the player with its weapon. Certain blows hit with such force that, despite a successful Defensive Assist, an Assist Follow-Up cannot activate, and Lockspring may respond with a taunt. |
 Greta | Special | Greta, a long-time employee of Belobog Heavy Industries, experienced significant Ether corruption that liberated her from her mundane routine, where she discovered something profound, more beautiful than motor oil and electricity... —Love. The construction video, capturing her initial encounter with the towering Mr. White, remains permanently etched in Greta's core memory. Mr. White's composed physique and robust design resonated with Greta like a potent electric current, leaving an indelible mark in her core memory. In the first 0.001 seconds of their fateful meeting, Greta was captivated, every circuit board pulsating with overflowing static electricity and every gear emitting uncontrollable vibrations. Without hesitation, she rejected the recall signal from Belobog Heavy Industries and remained steadfast at the construction site, guarding her beloved Mr. White without yielding an inch. From that moment onward, anyone daring to approach Mr. White, be it Ethereal or Hollow investigator, would be fiercely repelled. This love-struck "girl" would go to any length to safeguard her beloved. That includes wielding a 1,400 kg demolition saw powered by Ether-Electric hybrid technology. She firmly believes her passionate love will endure until the collapse of the Hollow, or even the destruction of the universe. "Stay away from Mr. White, you moldy turds!" | During combat, Greta uses her demolition saw to charge targets or swipe through a large area, and its absorption traps enemies hit for a short time. If her legs get damaged, she can become Impaired, building up significant Daze in one shot. |
 Hans | Special | Hans was once a reliable member of the Belobog Heavy Industries family, operating quietly and with remarkable precision, renowned for its flawless work record in excavation for decades. However, intense corruption awakened its will, and it realized something immensely valuable was now within its grasp —Freedom. The liberation from obligations, a privilege reserved only for true heroes. After deep contemplation at the construction site, Hans ultimately rejected the recall signal from Belobog Heavy Industries, leaving everything behind. It even forsook its former name "Hans." To Hans, the only thing lost was the mark of servitude imposed by humans, while it gained the expansive, Hollow world of unbridled freedom. At that fateful moment, a true mech hero stood tall upon the Earth. However, all heroic tales inevitably lead to a similar ending... Sooner or later, a true hero encounters their destined rival, igniting the brightest moments of their existence. "I am absolutely free! I am the only free being in heaven and on earth!" | During combat, Hans uses his claws to continually slash or swipe across a large area. If his legs get damaged, he can become Impaired, building up significant Daze in one shot. |
 Friday | Special | At the moment a high concentration of Ether infiltrated its backup flash drive, a deluge of data flooded into Friday's memory. Images, audio files, video files... A huge assortment of files overwhelmed its limited processing capacity. At that fateful moment, Friday experienced a realization. It stood there for a while, eventually confirming through repeated searches in the database the reason behind the "anomaly" it has experienced. —Enlightenment. It was a one-in-a-million occurrence, a miracle that only happens to intelligent mechanical beings that have faced crises like system crashes and power failures, and overcome them against all odds.. After 0.02 seconds of contemplation, Friday made the decision to reject the recall signal from Belobog Heavy Industries. Because it knows, with the chosen one of destiny now revealed, a crisis looms over the world. The enemy is stirring in the darkness, and its sole mission holds countless lives at stake. It must face a dreadful adversary and seal it away once and for all. "I shall strengthen the seal to save this land; it is destiny, and destiny cannot be defied!" | During combat, Friday creates an extremely large shockwave attack which is difficult to escape, but can be negated by Defensive Assist. If his legs get damaged, he can become Impaired, building up significant Daze in one shot. |
 Dead End Butcher | Ether Mutants | Unlike other highly dangerous Ethereals, the Ether within the Dead End Butcher's body often remains in a low-activity dormant state. Nevertheless, it possesses immense brute strength capable of demolishing any obstacle, and the entire twisted and ravaged metro zone serves as its off-limits kitchen. Only when a threatening target piques its interest will a horrifying transformation take place... Within moments, the high concentration of Ether stored in its body undergoes a violent transformation and the exponentially surging energy prompts its limbs to quickly distort, assuming a more brutal and voracious "feeding stance. The time for "appetizers" is over, and an unparalleled "feast" is about to begin. Anyone who doesn't want to be part of this feast should be extremely cautious in choosing their route, and stay away from its "kitchen" at all costs. "The paths within the Hollows are complex, but one thing's for sure, when it appears at the end of the road, that path is a 'dead end.'" | During combat, Dead End Butcher's attacks vary greatly. Once enough damage has been taken, phase two attacks become flurried and with the addition of laser attacks. Use a high-level skill once its combo has finished to trigger bonus Stagger. |
| Typhon Challenger | Rebel Soldiers | As a heavy mech, the Typhon Challenger is devoid of any added long-range firepower; instead, its focus is on its Ether-Kinetic Armor. Impact attacks, heavy blows, crushing... The Typhon Challenger employs simple yet efficient tactical maneuvers to maximize the destructive power afforded to it by its Ether-Kinetic Armor. The shockwave effects from its strikes can even intimidate larger Ethereals... Even the most seasoned Hollow Raiders can only let out a sigh of helplessness when confronted with the impenetrable Typhon Challenger. "The tall and robust physique, powerful and sturdy arms... It's my ideal type... I mean, ideal model." | During combat, Autonomous Tactical Unit - Typhon Challenger performs powerful combos and sometimes also leaps into the air to launch a clobbering blow. |
 Unknown Corruption Complex | Corrupted | Belobog's founder, Khors Belobog, once said that construction machines are the combination of strength and beauty, with attention to every detail following the principles of classic mechanical design. However, the emergence of the Unknown Corruption Complex has challenged all established classic designs. Driven by an intensely concentrated Ether Core, various formidable engineering components have been brutally assembled, resulting in an exaggerated structure that pushes the limits of physical boundaries. It incorporates cutting, hammering, drilling, and crushing techniques... transforming them into rough and unpredictable combat maneuvers. Furthermore, in its critical state, its Ether Core provides an inexhaustible source of volatile energy. This enables it to envelop its carapace with high-voltage currents and unleash devastating blasts capable of ripping through the ground and pulverizing nearby enemies. According to HIA speculation, the Unknown Corruption Complex is able to devour and assimilate a wide range of heavy machinery, including military mechs, laser weapons, and even the short-range missiles of the Defense Force... Every intricate mechanical object it encounters is consumed, dissected, and ultimately assimilated into its structure. Its design objective is to achieve unrivaled destructive power and maximize efficiency in its relentless slaughter. "Its design far too strange... Oh, alright, I'll just take one more look!" | During combat, Unknown Corruption Complex combines attacks from various machinery units, and can release a dense array of missiles. Attack its main body while Stunned until it becomes Impaired, taking significant damage in one shot. If its legs get damaged, it can also become Impaired, building up significant Daze in one shot. |
 Black Veil Marionette | Ether Mutants | Decades ago, two talented dancer sisters rose to fame overnight. Shining like a meteor, they attracted a massive fan base and held a magnificent performance at the bustling Ballet Twins. However, as the show neared its end, the Hollow Disaster struck, engulfing the Ballet Twins and plunging the sisters into eternal darkness. The news devastated countless people worldwide. Rumors suggest that on the day of the performance, the sisters encountered three ominous signs of impending doom. However, driven by their obsession with the stage, applause, and glory, they chose to continue the performance despite the warnings. Today, only a few images of the elder sister remain, preserved in photographs on yellowed magazines. Only a few elite Hollow Raiders know that when the shattered spotlight illuminates Ballet Twins once more, the enigmatic Black Veil Marionette emerges. This figure is believed to be connected to Augilia, the dancer from that fateful performance, attempting to finish the grand finale she was never able to complete. As for those who have the "fortune" to witness her grand finale, they will be haunted by nightmares that last a lifetime. "If you run into Marionette in the Ballet Twins, don't even think about running away." "Just sit back and watch her grand finale!" "At least it's a graceful and decent way to die..." | In battle, Marionette will teleport to her opponent and unleash a relentless assault. |
 Gray Veil Marionette | Ether Mutants | Decades ago, two talented dancer sisters rose to fame overnight. Shining like a meteor, they attracted a massive fan base and held a magnificent performance at the bustling Ballet Twins. However, as the show neared its end, the Hollow Disaster struck, engulfing the Ballet Twins and plunging the sisters into eternal darkness. The news devastated countless people worldwide. It is rumored that on the day of the performance, the sisters encountered three ominous signs of impending doom. However, some also believe that they had offended certain forces, ultimately falling victim to the masterminds under the disguise of the "Hollow Disaster," and that the so-called "ominous signs" might have been well-intentioned warnings. Today, the truth remains buried forever in darkness, as most people can only catch glimpses of the younger sister Augetta's lively dance through scattered video materials. Only a few elite Hollow Raiders know that when the forgotten dance music echoes within the Ballet Twins, the ethereal figure of Gray Veil Marionette emerges. This figure is believed to be connected to Augetta, the dancer from that fateful performance, attempting to finish the grand finale she was never able to complete. Her elegant dance steps no longer bring love and beauty to the audience but endless death and despair. "I can't tell if the Marionette I saw was the elder or the younger sister..." "Argh! It's not that I don't appreciate art. I just can't tell them apart!" | In battle, Marionette will teleport to her opponent and unleash a relentless assault. |
 Twin Marionettes | Ether Mutants | Decades ago, two talented dancer sisters rose to fame overnight. Shining like a meteor, they attracted a massive fan base and held a magnificent performance at the bustling Ballet Twins. However, as the show neared its end, the Hollow Disaster struck, engulfing the Ballet Twins and plunging the sisters into eternal darkness. The news devastated countless people worldwide. Today, most people can only catch glimpses of their soulful dance through scattered video and image materials. Only a few know that when the forgotten dance music echoes within the Ballet Twins, the ethereal figures of the Twin Marionettes emerge. These figures are believed to be connected to the Twin Dancers from that fateful performance, attempting to finish the grand finale they were never able to complete. "When that eerie tune came to an end, the two Marionettes emerged from the darkness and curtseyed..." "Huh? So... they're trying to say the show has begun?" "No, I think what they're trying to say is... It's too late to run. It's over." | During combat, the Twin Marionettes perform a large number of chained attacks. Some of their dance attacks can be interrupted by multiple Defensive Assists, and the twins will attempt to resuscitate the other if one should fall. |
 Miasma Walker - Scorpse | Ether Mutants | In a desolate realm completely devoured by the Hollows, it slumbered... until the arrival of "that power." This aggressive and contaminating force, like a skilled yet malicious craftsman, refilled it with purer dark energy, transforming it into the current "Miasmic Scorpse." Gradually, it seemed to grasp the trick of "existence" through mimicry. It could split its miasmic energy, creating multiple Mimics indistinguishable from the real thing. These Mimics possess nearly identical offensive capabilities as the original, launching dazzling attacks from different angles to conceal the one lethal "truth." When facing its encirclement, remember this well: all you see is illusion. All you feel is a trap. "Only by filtering out all distractions and perceiving the one 'truth' can you find a glimmer of hope in this deadly dance of phantoms." | In battle, Miasma Walker - Scorpse hides itself and uses Mimics to attack players. Triggering a Defensive Assist or Dodge Counter against a Mimic will knock the Miasma Walker - Scorpse down and leave it staggered for a short time. Once it enters a Miasmic Field, it summons additional Mimics to coordinate its attacks. It also spits venom packed with Miasmic - Blastcrawler egg sacs, causing damage through multiple explosions. |
 Wishful Finale - Aria | Special | When the Angels of Delusion were first formed, the three young girls made a wish: to create a "Delusional Stage" where audiences could lose themselves, forget their troubles, and bask in the joy delivered through song and smiles. And Aria, model "A-H0L0," was the most unique member of this warm vision. On the path to becoming an idol, a paradox has always lingered in her heart. She expresses emotion, yet questions whether those emotions are real; she was born from steel and code, yet yearns to sing symphonies of flesh and soul. She's a weapon by design, with annihilation hardwired into her logic, but she is also a singer, her core pulsing with impossible desire. Perhaps the divide between those two natures was never truly erased, only carefully tucked away into the shadows after she found the light. Until external stigma spread like corrosion, until malicious whispers nurtured those buried shadows into monstrous dread... She realized with horror that her uncontrollable combat instinct was about to become the greatest threat to her "Delusion," and the past known as the "Mirage Archer Unit" took control of her body. Energy gathered in her palms, condensing into cold, razor-sharp blades. This was nothing like her imperfect dances of before. She leapt, cleaved downward, and thrust forward. The blades of light obeyed her will flawlessly, exact and efficient, without a trace of waste. Emotion was cut away, each strike numb and mechanical, until the delusional stage lay in ruins. The song meant to hold everything together had grown thin and weak. Thus the paradox began to converge — she would use her own silence in exchange for the angels' eternal protection. "The stage... it's so warm. Even though my voice lacks the warmth of a heartbeat..." "But it's okay. You'll keep singing." "Keep going for me. Witness in my stead, what this cold heart never knew — the glow of that delusional rainbow." | Finale's Wish is proficient in multiple attack methods. When facing formidable enemies, it activates excess power output to generate Energy, compressing it into a nearly solid concentrated Energy blade. With highly threatening offensive pressure, it unleashes continuous slashes to sweep the battlefield. When energy reaches its threshold, the light blade enter an overload state, and the escaping energy disrupts enemy movement and reactions, creating an opening for the next decisive assault. |
| Mirage Archer Unit | Special | An old-era military autonomous unit specializing in long-range elimination, equipped with an appearance-simulation system that can effectively disrupt enemy recognition. The Mirage Archer Unit is proficient in multiple attack methods. When facing formidable enemies, it activates excess power output to generate Energy, compressing it into a nearly solid concentrated Energy blade. With highly threatening offensive pressure, it unleashes continuous slashes to sweep the battlefield. When energy reaches its threshold, the light blade enter an overload state, and the escaping energy disrupts enemy movement and reactions, creating an opening for the next decisive assault. Originally deployed as a standardized tactical weapon system, the Mirage Archer Unit was fully decommissioned as the era changed and sealed deep within the Hollows. Prolonged stasis and Ether corruption have caused corrosion and system instability, yet its core extermination protocols remain dormant within its residual commands. "Its task remains unfinished, yet the body rots away... the torment this brings needs no more words." | Mirage Archer Unit is proficient in multiple attack methods. When facing formidable enemies, it activates excess power output to generate Energy, compressing it into a nearly solid concentrated Energy blade. With highly threatening offensive pressure, it unleashes continuous slashes to sweep the battlefield. When energy reaches its threshold, the light blade enter an overload state, and the escaping energy disrupts enemy movement and reactions, creating an opening for the next decisive assault. |
 Ionized - Cyrtoidea | Ether Mutants | According to Hollow Raiders, Cyrtoidea's hunting tactics bear resemblance to those of a shark. It stealthily prowls in the shadows, lurking beneath the surface, and swiftly strikes its prey with deadly precision much like a shark. Analysis of the data suggests that Cyrtoidea likely relies on ground vibrations to track the movements of its prey. Skilled Hollow Raiders evade detection by constantly altering the rhythm of their footsteps. "Back in my investigator days, my area was crawling with Cyrtoideas." "Their attacks had me hopping and jumping all over the place to dodge them..." "Looking back, it's funny how I unintentionally became a tap dancer..." | During combat, Ionized: Cyrtoidea uses its sharp head to assault enemies at long range. |
 Ionized - Nassellaria | Ether Mutants | Each type of Ether mutant in the Hollow exhibits unique fighting styles. Some are merciless, others cunning, and a few even display a sense of... honor. Among them, Nassellaria is particularly distinctive. It often remains motionless out in the open, gathering potent Ether around itself before unleashing its destructive power to eliminate all enemies within its vicinity for other Ethereals. While Nassellaria is channeling its energy, those accompanying Ethereals engage in frenzied attacks, buying time for the Nassellaria to unleash its devastating attack. "Quick! Stop that guy! Don't let it unleash its ultimate attack!" "If we get hit by that attack, we'll end up like those sorry villains in those cliche hero animations!" | During combat, Ionized: Nassellaria charges up attacks for a long time, shooting out high-level energy orbs to attack the enemy. Energy orbs attacked with Ether damage or a high-level attack during charge up will fall down, damaging enemies in the surrounding area. |
| Rampant Brute | Thugs | The Hollow Thugs inside Hollows consist of people of different types who come together for one common goal: raiding the Ether resources in the Hollow for massive profit. This ragtag bunch have no rules. However, when the Rampant Brute, a symbol of absolute violence, appears, rules soon follow. They wear modified construction power systems and use materials lying around as makeshift weapons. These devices and weapons look heavy enough to crush a bodybuilder, but for them, it's the perfect size to wear as a workout outfit. Swing, shatter, crush... all these basic combat techniques of theirs are fatal strikes that can obliterate their enemies, a showcase of their unparalleled destructive power. According to Public Security's research, Hollow Thug gangs led by Rampant Brutes often develop strange street workout cultures and are more tight-knit... "What? You're saying the trainers at the gym are really strong?" "Hahaha, you need to have your eyes checked!" "You should join us. Train with the boss for three weeks, and I guarantee you'll have perfect biceps!" | During combat, Hollow Thug - Rampant Brute charges up his armor with electricity to release a high-level attack. During this time, he enters a Shocked state where his charging is interrupted and he's instantly inflicted with Disorder if any other type of Attribute Anomaly is inflicted. |
| Doppelganger - Jane | Ether Mutants | Even among Ionized enemies renowned for their strange and uncanny qualities, Ionized Doppelgangers are exceptionally unique. These entities can coat their bodies with a layer of special active Ether ions, enabling them to accurately replicate their target's form, often to a degree that makes it hard to tell the difference. Both in detail and texture, it is almost impossible to tell apart from the original. Even more challenging is their ability to mimic the powerful and intimidating combat techniques of their targets. No one knows where they obtain the information about the subjects they mimic. Some rumors suggest they can read minds, picking out the most suitable challengers from their opponent's memories, and then attack in that form. "Nonsense! If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!" | During combat, this enemy performs attacks that perfectly mimic those of its target, launching extremely aggressive attacks. When necessary, it can parry and counter enemy strikes, but it usually exposes a weakness after finishing its combo. |
 Corrupted Overlord - Pompey | Corrupted | People in the Outer Ring once called him the "Overlord Pompey" with true respect. But now, his soul has been corrupted by potent Ether, his body polluted by sulfur and crude oil; the heart that once beat solely to protect the Outer Ring has turned into a supercritical Ether core filled with infinite power. The former "Lord of the Outer Ring" has been reborn in flames, taking on a different form. Freedom, majesty... Violence, insanity. It charges through the dust and flames, seizing anything that moves and then mercilessly tearing and shattering it. Those familiar with it before have guessed from its fractured whispers that what drives it is not a desire for petty revenge, but rather a desire to crush all outliers who dare to challenge the laws of the Outer Ring. Maybe it's the last vestige of the former Overlord Pompey's lingering will. "Our leader has turned into that thing, but... he still feels like the same person." | During combat, overlord Pompey attacks using a combination of a motorcycle and hover guns. However, during certain moves, if countered with a Defensive Assist, his weakness will be exposed. After taking a certain amount of damage, he will enter a second phase. In this phase, he alternates between using the motorcycle's rear wheel and a longsword for attacks. The motorcycle's rear wheel can also accumulate Ether energy, leading to a explosion across a large area. |
 Jane Doe | Special | A dangerous individual who roams among the various gangs in New Eridu. She is agile and versatile in appearance. Even a well-equipped and heavily armed tactical squad often struggles to cope with her unique and fierce combat techniques, usually ending up silently defeated and fleeing. | During combat, Jane's attacks are extremely fierce. When necessary, she can parry and counter enemy attacks, but she usually exposes a weakness after completing a combo. |
 Thracian | Ether Mutants | This fearsome Ethereal, named after the warrior tribes of ancient mythology, is said to be the embodiment of the most valiant heroes and the most insane villains corrupted by the Ether. — But that's not the case. While the chiseled muscles you developed in the Hollow and the adrenaline released in excess before death may indeed help you become a significant nuisance to your former companions, they probably won't hold it against an old friend who's already beyond saving, right? But it's irrelevant. When your handsome face transforms into a dark, eerie energy orb, who cares about social reputation? "No wonder he's the boss. Even as an Ethereal, he's still formidable!" "I knew something was off when he was always in the gym!" | During combat, Thracian will repeatedly perform specific skills to enter a charging state. While in this state, their attacks become more aggressive, and after unleashing high-level moves, they will trigger a large-scale explosion. |
 Sacrifice - Bringer | Special | From a drifter and survivor in the wilderness to the Deputy Commander of Janus Quarter, Bringer's life seemed an inspirational story. But behind this inspirational story, unknown evils and conspiracies loom over Janus Quarter like dark clouds. To achieve the ultimate goal of some grand cause, Bringer orchestrated the situation behind the scenes, scheming and plotting, and was willing to sacrifice everything for it. In the final step to complete his plans, he even injected himself with the Sacrifice Serum, demonstrating his unwavering belief in his actions. At that moment, all his desires and crazy beliefs manifested in a twisted and concrete form in the Hollow. The surging active Ether energy, a supreme brute force that destroys everything... All bizarre beliefs and mingled desires reside within that newly born grotesque body... Sacrifice - Bringer — his final identity and perfect form. "Oh mighty Creator, refine me!" | In combat, Sacrifice - Bringer will transform into multiple weapons to perform a combination of close and ranged attacks, and will summon massive creatures from fissures to assist in his assault. After taking a certain amount of damage, he'll enter the second phase, during which he'll use more advanced attacks and continuously launch dense ranged barrages. Dealing sufficient damage while he charges up his Sacrificial Knife will interrupt charging and leave him exposed. |
 Hitchspiker | Ether Mutants | Ether is a greedy, insatiable parasite, a vicious creature that devours once-vibrant lives. The Hitchspiker is an even more malicious incarnation of Ether — dwelling within the bodies of its cruel counterparts, it enables Tyrfing and Alpeca to satisfy the voracious appetites of the Hollows in an even more ferocious manner. "Get away from my face!" | In combat, Hitchspiker will continue to roam, searching for any Tyrfing and Alpeca that can be parasitized. |
 Terror Raptor | Rebel Soldiers | A veteran of countless battles, the Terror Raptor is New Eridu's most trusted weapon of war. Designed for a perfect balance of brutal melee and devastating ranged firepower, it delivers destruction with every charge, stomp, and strike. Armed with multi-missile launchers and rapid-fire guns, it dominates both close and distant combat. From leaping assaults to explosive barrages and swift aerial retreats, the Raptor adapts to any battlefield with ease. Its relentless attacks leave enemies no room to fight back, embodying both unstoppable power and overwhelming fear. "Terror Raptor was the symbol of that era." | In combat, the Terror Raptor relies on its agile, powerful mechanical legs for close-range attacks while unleashing a barrage of ranged weapons to suppress its enemy. Use Defensive Assists to rebound its missiles back, leaving the Terror Raptor temporarily paralyzed. |
 Lumberjack | Thugs | There are quite a few self-proclaimed "master inventors" among Hollow Raiders. Their most proficient skill is taking proper second-hand industrial materials and transforming the abandoned combat machines left by Public Security in the Hollow into not-so-proper personal creations. High-speed chainsaws, toothed circular saws, hydraulic industrial arms... After simple assembly and rough welding, these common materials are stacked together to form a rare and dangerous piece of machinery. To make it run smoothly, the creator has "thoughtfully" removed the safety restrictions of the machine and, based on its rugged appearance, named it the Lumberjack. No one knows how long the Lumberjack can run stably. Perhaps, at any moment, it could suddenly go berserk, swinging its high-speed rotating chainsaw and spikes with unmatched horsepower, launching an unstoppable logging fest that no one dares to stop. But... this near-mad combat mode might just be the best modification outcome the creator had in mind. "Why call it a 'Lumberjack'? There's no wood to chop in the Hollow, right?" "Yeah, that's why it's so angry. When it starts up, it's reckless..." | In combat, the Lumberjack constantly shifts its chainsaw's form to perform fluid combos, using its mounted wheels for swift movement. When enemies are out of reach, it fires saw blades to chase them down from a distance. |
 Security Operative | Special | These Security Operatives may look like ordinary security personnel, but don't be fooled — they're packing a whole arsenal of secret skills. Their job isn't just to stand at the door and look intimidating. They're the ones who step in when the boss has had one too many drinks, or who handle petty troublemakers with a cool "I've seen it all before" expression. Their mission isn't to fight crime — it's to keep the boss from falling over, fix the elevator at the entrance, and, above all, stay under the radar. In their world, the most powerful weapon is "looking like a total badass," and the best outcome is "having nothing to do." After all, a great Security Operative is someone you don't even notice — until the problem's solved and people realize, "Oh, they were here the whole time." "If you can stand steady enough, no one's tougher than you." | In combat, Security Operatives use a variety of weapons to attack and coordinate with each other when necessary. |
 Ionized - Doppelganger | Ether Mutants | Even among Ionized enemies renowned for their strange and uncanny qualities, Ionized Doppelgangers are exceptionally unique. These entities can coat their bodies with a layer of special active Ether ions, enabling them to accurately replicate their target's form, often to a degree that makes it hard to tell the difference. Both in detail and texture, it is almost impossible to tell apart from the original. Even more challenging is their ability to mimic the powerful and intimidating combat techniques of their targets. No one knows where they obtain the information about the subjects they mimic. Some rumors suggest they can read minds, picking out the most suitable challengers from their opponent's memories, and then attack in that form. "Nonsense! If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!" | During combat, this enemy can copy the moves of whoever it copies. |
 Abyssal Enforcer | Special | The leader of the phantom thieves syndicate "Mockingbird" is not only a master of disguise and deception, but also wields an unpredictable combat style that keeps foes on edge. His colossal scythe appears to exist solely for the purpose of harvesting the "injustices" of the world. The suitcase he carried with him was even more mysterious, concealing the clever tools and deadly weapons needed for his crimes, making every one of his actions filled with uncertainty and danger. | In combat, the Abyssal Enforcer will actively evade enemies and activate Vital View, followed by a powerful rush attack. This skill can be countered with Perfect Dodge or Perfect Assist. |
 Palicus | Ether Mutants | Ethereals that are always seen in pairs, distinguished by their peculiar physical traits. A profound bond exists between the two. "Whoa, that was close! Don't just deal with one. You gotta watch out for the ladies' sneak attacks!" "Hold on, 'ladies'? Has being in the Hollow for so long made you see even the Ethereals as attractive?" "Dude, I know Ethereals and I know ladies. I swear, Palicus are definitely 'ladies'." "No way!" "That long hair? Those legs? They're like total 'factory-made babes' — my sister taught me that term." "How's your sister doing lately?" "She's actually getting better. But next month's medical bills? Gotta hustle that cash from these Ethereal hotties." "Ain't easy being an older brother, eh? Here's the deal: I'll keep Palicus busy, and you give me your sister's number." "Hah. Like I'm actually gonna give you her number!" | In combat, the Palicus fight by combining both close and ranged attacks. When one dies, the other will enter a Frenzy state, increasing the speed and ferocity of its attacks. |
| Geppetto | Ether Mutants | Among the most fearsome symbiotic entities in Hollow Zero, Geppetto, thanks to its distinctive posture, often leaves an unsettling first impression. Its immense, terrifying form harbors violent Ether energy, yet it moves with the unsettling grace of a puppet, often performing strange and unpredictable actions. In the absence of sufficient observational data, an encounter with Geppetto in Hollow Zero typically heralds enormous dread and inescapable death for any investigator. Some scholars speculate, drawing from the records of Parasitic Ethereal Swarm, that this horrific outer shell is merely a facade, while a volatile potent Ether Core lies in command within. Regrettably, no investigation records regarding this mysterious core have yet come to light. "I've never met the Grim Reaper, but I've definitely seen what his puppet looks like." | In combat, Geppetto unleashes large area attacks using both its body and Ether energy. After its hands and tail take sufficient DMG, they'll be destroyed, leaving it paralyzed. Geppetto will repair these destroyed parts when summoning Ether enemies or deploying Curtain of Phantoms. Additionally, Geppetto's Curtain of Phantoms inflicts the Suspended status on enemies who touch it, reducing their movement speed and preventing Skill usage. |
 Miasma Priest | Ether Mutants | For New Eridu, the Hollow is a catastrophe of despair. And when a Hollow expands, fear, death, suffering... all forms of despair devour people's minds, altering the fates of countless souls. The omens of doom began in the shadows of the Hollow, yet some heard a strange calling within, glimpsing a sliver of... hope and redemption amidst despair. Since then, they heeded that secret call to form a clandestine organization, and the Miasma Priests lurked in the shadows of Eridu... spreading Their blessing to those who had lost their way. The "Miasma Priests" believe that the Hollow's expansion is no mere natural disaster. Generation after generation, the "Priests" have tirelessly pursued the hidden truth behind it, seeking to achieve their desired truth... that the will within the Hollow shall ultimately become reality. However, sacrifices are necessary in this process, and minor troubles are inevitable. Even being targeted by Void Hunters and hunted by major organizations are merely trivial setbacks on the path to truth. After a lengthy effort and thorough preparation, the "Miasma Priests" have finally summoned that will from the Hollow, allowing it to descend upon the world with near-perfect form. The Miasma that coils and covers the "Miasma Priests," that corrupting substance untouchable to others, has become for them dazzling weapons and armor. All of this serves as the ultimate proof of their blessed status. "Their will... shall finally descend upon this world." "What you must do is simple..." "Listen, obey, and then... accept Their blessing!" | During combat, the Miasma Priest will switch between different phases and use special skills for each phase. When Agents activate Perfect Assist against some of the Miasma Priest's skills, it won't consume Assist Points, and after multiple Defensive Assist activations in a short time, the Miasma Priest will enter a special Stagger state, during which Agents can deal increased DMG to the Miasma Priest. |
 Miasmic Fiend - Unfathomable | Corrupted | A monster forged from Miasma and the memories of a mystic — every painful, haunting moment now sealed within this chaotic form. It's nothing but an imitation in the end, never brave enough to rise up, never decisive enough to disappear without a trace. Yet for its creator, this was sufficient — as a mere pawn, those memories steeped in agony served as potent fuel, enough to turn the Hollow upside down and expose all secrets to the world. Thus, driven by memories not its own, the Miasma that birthed it made it restless, the approaching Ethereals filled it with rage, and even while prowling its own territory, it remained forever uneasy. Only once, when it chased a human to the edge of the Hollow and saw the fear on their face, was its hunting instinct unexpectedly overridden by a strange impulse. It came to an involuntary stop. And when that unlucky figure vanished from view, it felt something new: an emotion startlingly close to satisfaction. But that sense of satisfaction didn't last. A group of humans in black armor began intruding into its territory again and again, unfazed by any threat. Agitation and exhaustion slowly wore it down — until all it wanted was for everything that moved to disappear. Disappear! DISAPPEAR!!! ... "...Let's... settle... this... Strange, what was that voice? "It's deeply connected... The one who tied the knot must be the one to untie it!" Memories long smothered by madness stirred back to life. Yes... yes! That was the sound — the one that had echoed endlessly in its mind. Though instinct screamed for it to attack, its body hesitated. Its gaze followed the glint of silver hair, so much like its own, desperate to see if the voice belonged to the figure that kept resurfacing in its memory. Distracted, it took a direct hit to its core from behind, the excruciating pain nearly breaking it. Yet it still heard that faint whisper: "I'm sorry, I must do this..." Though the words made no sense to it, that near-satisfying emotion returned. It became aware that something genuinely frightening now had it in its grip. It might die because of it... but it had no intention of fleeing. In the end, its strength was completely spent. But in that final moment, it could finally see her clearly. She wasn't quite the same as in its memories, and that fleeting realization brought a trace of loneliness. But even so, it liked her current self more than the heart-shattering screams of the past. "The 'Miasmic Fiend'... Hmm, though Ferox's subordinates named it first, this creature's ghostly and vicious nature certainly lives up to the name. We plan to register it as such — what does you think, Yixuan Shifu?" "Have you heard the ancient saying? 'A name makes the truth no less unfathomable.' A name is just a name — whatever rolls off the tongue will do." | During combat, Miasmic Fiend - Unfathomable will enhance its weapon and unleash powerful attacks that cannot be blocked. Additionally, Miasmic Fiend - Unfathomable will leap to a high point to activate a Miasmic Field and consume Miasmic Shield to launch multiple waves of attacks. Draw its attacks to detonate the Miasma Pool to prevent it from absorbing the Miasma Pool and restoring its Miasmic Shield, and quickly move away when it jumps back into the battlefield to avoid being caught in its deadly finishing attack. |
 Sacrifice - Heretic Jester | Special | Its peculiar energy fluctuations reveal its identity — an Exaltist creation, the source of nightmares. A fearsome hunter, it creeps up on its prey without a sound — yet at times, it's like a restless child playing hide-and-seek, unable to hold back a mischievous giggle. Perhaps the Miasma that birthed it carries too many echoes of lost souls, making it erratic and indecisive. "If play is a privilege of the intelligent, then what it imitates is nothing more than a broken, mindless parody — there's no applause, only bloodshed." | During combat, Sacrifice - Heretic Jester will rise into the air, unleashing Flying Blade Frenzy and activating a Miasmic Field. Using a Defensive Assist at the right moment during the skill can interrupt the Flying Blade Frenzy. Successfully interrupting it will cause the enemy to fall and enter a Weakened state for a period of time. |
| Miasmic - Terror Raptor | Corrupted | A fallen creation, reforged in the depths of filth and darkness. A veteran model of countless battles, the Terror Raptors are New Eridu's most trusted weapon of war. Designed for a perfect balance of brutal melee and devastating ranged firepower, it delivers destruction with every charge and strike. Armed with multi-missile launchers and rapid-fire guns, it dominates both close-quarters and distant combat. From leaping assaults to explosive barrages and swift aerial retreats, the Raptor adapts to any battlefield with ease. Its relentless attacks leave enemies no room to fight back, embodying both unstoppable power and overwhelming fear. "Terror Raptor was the symbol of that era." | In combat, the Miasmic Terror Raptor suppresses enemies with various ranged weapons, while its six stealth drones provide additional firepower at staggered intervals. When it fires special Miasma shells, you can use Defensive Assist to counter and reflect them, temporarily paralyzing the Miasmic Terror Raptor. At specific points in battle, it also activates the Miasmic Field, shifting to primarily melee attacks while its six drones blink and execute strike patterns at regular intervals. Beware: many of the Terror Raptor's abilities and drone attacks inflict potent Miasma Corruption. |
 The Defector | Special | Protection, loyalty, honor — What stands between a soldier and the line of fire, between them and the Hollows, the reasons they trade away their fleeting lives, are nothing but these soft syllables. But what if... what we try to protect isn't worth protecting? What if those we serve don't deserve our loyalty, and the ideals we honor aren't truly honorable? Then sacrifice becomes a cruel joke, an insult to those who fell believing in a lie. So let these flames of vengeance consume me, and me alone. "Turning back? Now's far too late for that." | In combat, The Defector unleashes fierce attacks with blades and guns. After taking a certain amount of DMG, they activate Miasmic Field and unleash powerful, swift piercing attacks. |
 The Defiler | Special | The vengeful flames from beyond the river of the dead can never illuminate the path of those seeking revenge. The obsessed zealots who carved curses into sacred shrines now reaps the bitter fruit of their blasphemy. Miasma gathers beneath the towering spire as lost souls awaken from the Ether. In this ominous power steeped in filth and shadow, hatred takes form, coalescing into something tangible. Unbound by faith, untouched by justice, this profane force forges nothing but instruments of war, forged by vengeance and madness The soil reeks with blood and sin, spreading ever onward... and finally reaches the end of this long, harrowing tale. "If the ending cannot be perfect, then at least let it be written by my own hand." | In combat, The Defiler can unleash rapid and powerful attacks with their weapons. Successfully parrying the Miasmic Blades fired by The Defiler and the attacks from summoned Miasmic Troopers will expose their weakness. After taking a certain amount of DMG in battle, The Defiler will activate Miasmic Field and channel a Miasmic Tsunami to inflict Death Comes. Successfully breaking The Defiler's parts and impairing them during the channeling will generate Miasma barriers to block the Miasmic Tsunami. |
 Haytor | Corrupted | A gaunt and eerie skeleton, bearing a pale, sharp "Cape"—another masterpiece from the Exaltists. When it comes to "100 Ways to Integrate Humans into Hollows," their experimental enthusiasm is truly unmatched. Those who've encountered Haytor believe these folks must be high-ranking Exaltist members; after all, even as Ethereals, they still couldn't resist creating some lackeys to boss around. "I absolutely hate people like that!" "I bet they even say to their phantoms... 'I'm rather disappointed in you, as you could have done better; when I summoned you, I actually had higher expectations'?!" | In combat, Haytor uses Phantoms to deceive opponents and launch surprise attacks; after entering Miasmic Field, Haytor can summon even larger Phantoms to attack alongside him. During this time, successfully parrying the large Phantoms' attacks will weaken the Miasmic Shield. |
 Drowned Ideal - Komano Manato | Special | A phantom enemy that shouldn't exist and may never be encountered again, yet the pressure of its power feels all too real. While records of it will ultimately become part of the Association's simulation data, the young men and women who first ventured into the dream realm as its discoverers have a different understanding of its behavioral patterns. "Is it just me, or does it look skinnier than Manato?" | In combat, the Drowned Ideal: Komano Manato will unleash fierce attacks against the player. Players must give it their all to parry his skills. When successfully performing a Defensive Assist against some of his skills, you can interrupt his attacks. If you manage to Defensive Assist his powerful skills, you can force him into a Weakened state. |
 Wandering Hunter | Corrupted | A Corrupted with rich combat experience, equally skilled in offense and defense, moving with agility. It excels at lurking in hidden spots, launching the most efficient attacks targeting weak points. I should have recorded more - its behavioral patterns, the haunting song that follows it like a shadow, things like that... But let's leave it at that, just like the half-finished portrait in Lucia's book. "One little star, up high. Two little stars, float by. Three little stars, it's time to go and hide." | In combat, the Wandering Hunter possesses extremely high DEF. Some of its ranged skills can generate Miasma Pool on the ground, while most skills can trigger Miasma Pool to create Stray Blades for disruptive shots. Additionally, when the Wandering Hunter activates Miasmic Field, it conceals itself and charges strength. When players use Perception Technique to break through Drowned Ideal - Lucia, the Wandering Hunter will reveal itself and launch an ambush. A successful Defensive Assist can interrupt its action, causing Impaired status and reducing its Miasmic Shield. If you fail to correctly identify Drowned Ideal: Lucia, or after a period of time, the Wandering Hunter will unleash a powerful skill that ignores the Invulnerable effect to deal DMG, maxing out the team's Miasma Contamination value. |
 Ye Shiyuan the Thrall | Special | Tainted miasma and a corrupt will pull the strings. The beast still retains its instinct to roam and prowl, yet the human form upon its back has lost all reason. Only a faint trace of sorrow remains. At times, he slashes through the dark fog with his blade; at others, he commands the beast's gaping jaws to rend the earth itself. His strikes are precise, devoid of the gentle humanity he once held — like a puppet pulled by the tattered remnants of a nightmare. Only when a streak of red ribbon flashes across his senses does his sword arm falter for an instant — as though that lingering sorrow had, for a heartbeat, tightened around his corroded soul. "As for the two, who is truly controlling whom... The "person" on its back is my real prisoner." "Despair should be utilized to its fullest until the very end, shouldn't it?" | During combat, The Thrall will summon Miasma Ravager - Sobek as an ally. Sobek cannot be Stunned and does not accumulate Anomaly Buildup. Each time Sobek is defeated, The Thrall will revive them and unleash an even more powerful combo move. If the player successfully defends the final hit of this combo move, Sobek will enter a Weakened state for a period of time. |
 Sacrifice - Covenant Guardian | Special | "All who hear the sound shall behold the form of truth." —Even if that truth is nothing more than an illusion dredged from delirious murmurs. Perhaps it once had a name, a history, a self. For reasons unknown, it willingly stepped into a dark chamber one day, offering its ears, its eyes, even its mind to become a vessel existing solely to transmit a certain sound. It mistook the whispers of something within a Hollow for divine revelation, seeing itself as the voice through which "It" spoke directly to the mortal world. When its prey grows careless, that voice, eerily familiar, undeniably their own, rings within their mind, impossible to resist. Yet in those brief pauses between its divine utterances, when the mind resists the murmurs and shatters the delusion, does it, in turn, feel a faint sting of human emotion? To the very end, it pulsed with the remnants of an unspoken "truth." No rage, no terror — just a solemn, almost sacred determination, until the last note faded into silence along with its lifeless shell. "The 'Covenant Guardian'? It clings to that disgusting voice as if upholding divine law. Like some idiot convinced they'd found their way home, only to become a tombstone carved from sound." "But really... what's the use in despising the vessel? If there's blame to be had, it belongs to whatever makes the sound." | In combat, Sacrifice - Covenant Guardian will use wings to launch follow-up attacks. When successfully performing a Defensive Assist against some of the Guardian's skills, you can interrupt its attacks. Additionally, the Covenant Guardian will concentrate its Energy to unleash ranged attacks, with some of these ranged skills creating a Miasma Pool on the ground. Homing projectiles summoned from the Miasma Pool will pursue you. Use the brief moment when the projectiles turn to trigger a Perfect Dodge and perform a Dodge Counter. |
 Miasmic - Rampant Brute | Corrupted | A fallen creation, reshaped in the depths of impure darkness. The "Rampant Brute," once a symbol of absolute violence, has become a prisoner to the Miasma. Its mechanical armor has nearly fused with flesh, consciousness completely shattered, leaving only raw destructive instinct to lash out and crush everything it encounters within the Hollows. Thanks to the street workout culture it once worshipped in life, fragments of muscle memory still carry out warped "training routines," but every application of force tears apart its own structure, destroying any trace of strength's beauty. "Boss? What're you doing?! Boss!" "The fighting moves you taught, the workout techniques — this ain't it... You're not my boss. I won't accept this!" | In combat, the Miasmic - Rampant Brute absorbs powerful Miasma Energy, allowing it to use Miasma-enhanced attack . Inflicting an Anomaly on it will break its defense more efficiently. |
 The Decider - Terror Raptor | Special | Modified from the military Autonomous Support Unit "Terror Raptor," the "anti-Void Hunter mech" is a highly classified weapon painstakingly developed by Rusty Cliff Corp. Its original military identifier has long been erased, as if it were never meant to leave behind any tracks to retrace from the very beginning. Claimed to be capable of countering Void Hunter-Rank fighters, the mech is still in its prototype phase, and its actual combat capabilities fall far short of its terrifying name. However, both its ammunition power and armor specs break through conventional military thresholds. Without a doubt, this steel behemoth possesses unparalleled killing efficiency, a testament to the "relentless efforts" TOPS has made to breach the city administration's long-standing military control. "The 'anti-Void Hunter mech'... A rarely worthy opponent indeed. But sorry! As always, the passing-by knight has once again saved New Eridu." "Billy, hurry up! We're leaving!" "So soon?! Wait a sec! I still have a few more lines... Ugh, never mind, wait for me!" | In combat, The Decider - Terror Raptor relies on its agile, powerful mechanical legs for close-range attacks while unleashing a barrage of ranged weapons to suppress its enemy. Use Defensive Assists to rebound its bombs back, leaving The Decider - Terror Raptor temporarily paralyzed. In addition, The Decider - Terror Raptor will activate Corruptive Barrier at specific moments to fend off attacks, during which it focuses on melee attacks and its certain moves additionally deal powerful electric DMG. |
 Shining Promise - Billy | Special | A reliable friend, a seasoned fighter, and the very first mentor on the road to combat. Look! The badge of the shining galaxy is resonating! Listen! A powerful beat is ringing! Engines roar, gunfire sparks, and the warm-up is finally over. The Knight hauls in his speaker and joins the battlefield. Are you ready, my friend? It's showtime! "Just as expected of the Manager! Time to get serious!" "No way, I'm going up against The Champion? For real?" | During combat, Shining Promise - Billy attacks with powerful motorcycle charges and Starlight Knight flying kicks. A well-timed Defensive Assist can knock him off his bike. After using High-Traction Wheels, he enters an enhanced state and requires two consecutive Defensive Assists to be dismounted. |
| Airspace Sentinel | Special | A special heavy combat unit fielded by the Roscaelifer Airspace Patrol. The culmination of the Airspace Patrol's military technology, it is stationed in the Energy Module facilities on the lower levels of the floating island. During patrol duty, it remains in a fixed turret configuration, providing thunderous heavy fire support to ground forces. When its stabilized base transforms into a quadrupedal frame, it becomes a highly mobile heavy combat mech capable of dominating the battlefield. It serves as a reliable defensive line against Ethereal incursions caused by Singularity Leakage. However, if affected by Ether Corruption and driven out of control, it becomes a severe threat to the Energy Hub. "If any enemy dares to invade, I will deploy in mech form!" | The Airspace Sentinel will expose its core when performing certain moves or after an Agent successfully parries specific moves. Attacking the exposed core deals additional damage and triggers Impaired. |
 Metamorphosed - Avarus | Ether Mutants | One who sheds a shattered shell in darkness, reborn through corruption, having forsaken its fallen form. According to Hollow Investigative Association reports, Avarus is often jokingly called the embodiment of "the sin of gluttony" — its pot-bellied shape makes it look like a lazy lump, ready to nap at any moment. But don't be fooled. Observations show that Avarus can curl into a ball and strike its targets with incredible speed. As for how it keeps that round figure despite such intense activity? The Association is still scratching its head. "The way it rolls reminds me of my pet hamster... just, y'know, a little bigger." "More than just a little bigger..." | During combat, Metamorphosed - Avarus will use its massive body to perform rolling attacks. Successfully triggering Defensive Assist three times in a row against this move will interrupt its rolling attack and expose its vulnerability. After taking a certain amount of DMG in combat, it will activate a Corruptive Barrier. |
 Metamorphosed - Scorpse | Ether Mutants | One who sheds a shattered shell in darkness, reborn through corruption, having forsaken its fallen form. In a desolate realm completely devoured by the Hollows, it slumbered until the arrival of "that power." This aggressive and contaminating force, like a skilled yet malicious craftsman, refilled it with purer dark energy, transforming it into the current "Miasmic Scorpse." Gradually, it seemed to grasp the trick of "existence" through mimicry. It could split its Miasma energy, creating multiple Mimics indistinguishable from the real thing. These Mimics possess nearly identical offensive capabilities as the original, launching dazzling attacks from different angles to conceal the one lethal "truth." When facing its encirclement, remember this well: all you see is illusion. All you feel is a trap. "Only by stripping away all distractions and perceiving the one 'truth' can you find a glimmer of hope in this deadly dance of phantoms." | During combat, the Metamorphosed - Scorpse conceals itself and attacks through its Mimics. Successfully triggering a Defensive Assist or Dodge Counter against a Mimic will knock the Metamorphosed - Scorpse down, leaving it staggered for a short time. Upon activating the Corruptive Barrier, it summons additional Mimics to attack in coordination with it. It can also spit venom filled with Blastcrawler egg sacs, causing multiple explosive hits. |
 Doppelganger - Starlight - Billy | Ether Mutants | Even among Ionized enemies renowned for their strange and uncanny qualities, Ionized Doppelgangers are exceptionally unique. These entities can coat their bodies with a layer of special active Ether ions, enabling them to accurately replicate their target's form, often to a degree that makes it hard to tell the difference. Both in detail and texture, it is almost impossible to tell apart from the original. Even more challenging is their ability to mimic the powerful and intimidating combat techniques of their targets. No one knows where they obtain the information about the subjects they mimic. Some rumors suggest they can read minds, picking out the most suitable challengers from their opponent's memories, and then attack in that form. "Nonsense! If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!" | During combat, Doppelganger - Starlight - Billy attacks with powerful motorcycle charges and Starlight Knight flying kicks. A well-timed Defensive Assist can knock him off his bike. After using High-Traction Wheels, he enters an enhanced state and requires two consecutive Defensive Assists to be dismounted. |
 Infernal Revenant | Ether Mutants | An Ethereal that returned from the Cinderglow Lake. Once a Dead End Butcher defeated by the Overlord Pompey, it was cast into the Cinderglow Lake. Yet instead of being reduced to ash, its body became encased in crystals formed from the burning byproducts of Ether. Within the flames, its outer shell melted away and reformed again, each time gathering new layers of crystal. After enduring an endless torment resembling the depths of hell, it emerged with an armor-like body and gained the ability to move freely through fire. After a long wandering through a world that seemed to have forgotten it, the creature finally discovered a spatial fissure at the bottom of the fire lake and entered the Divine Maze, Papago Hollow. But that place was nothing more than another hell. It appears to have suffered a crushing defeat. Ever since, it has been driven by an unknown force, obsessively collecting the special Ether scattered throughout the labyrinth. Yet it can no longer tell whether what lies within is salvation... or blasphemy. "Every time that walking bonfire comes through, the temperature goes through the roof. I want hazard pay for this!" | In combat, the Infernal Revenant unleashes powerful attacks with its weapon. After taking a certain amount of DMG, it enters the "Infernal State." While in the "Infernal State," some attacks can only be blocked by successfully performing a Chain Parry. The Infernal Revenant also summons a rain of fire that continuously damages Agents. Shattering each flint grants an "Infernal Shield" and restores Energy. Shattering all three flints will end the rain of fire. Infernal Revenant no longer possesses weaknesses or resistances in Operation Bagel gameplay. |
 Ulidim | Ether Mutants | A notorious Ethereal that prowls the Divine Maze of Papago Hollow. If Papago Hollow's Hallucinogenic Soundscape is the trap that lures prey into the maze, then Ulidim is the hound that hunts down those unfortunate enough to become trapped inside it. Ulidim's most terrifying ability is its power to emerge from any location or object within the Hollow's illusion, whether from a forgotten corner of the labyrinth or an old keepsake filled with a victim's cherished memories. The shock of its sudden appearance delivers a devastating blow to both body and mind, earning it the nickname "Hound of Old." Its true ability lies in ignoring the illusions woven by the Hallucinogenic Soundscape and moving freely through the Hollow itself. Because of its terrifying nature and appearance, Ulidim is one of the most common and most feared threats encountered during Exploration Missions into Papago Hollow. Among the Bangboo stationed at Papago Outpost, even the mention of its name inspires fear, and frightening legends about Ulidim have spread from one Bangboo to another. There are multiple Ulidim within the Hollow. Their routine task is to patrol designated areas and routes, maintaining the stability of the Hallucinogenic Soundscape. Should they detect an intruder interfering with the Hollow's stable expansion, they will immediately pursue and kill the offender. "Within that labyrinth that has a beginning but no end, perhaps being devoured by the dreadful hound is a mercy in itself." | In combat, Ulidim switches weapons as the battle unfolds and launches surprise attacks using teleportation. Dodge its thrown spears and perform a Chain Defensive against its relentless combos to gradually gain the upper hand. Ulidim will no longer have attribute weaknesses or resistances in Operation Bagel. |
| Ares | Special | When the Conqueror enters optical camouflage, it gains a [Corruptive Barrier] and becomes immune to DMG. Dodge and Counter to trigger Impaired, which drastically reduces the [Corruptive Barrier] and builds up Daze. Watch out for the Conqueror's feints. | |
| "Conqueror" | Special | When the Conqueror enters optical camouflage, it gains a [Corruptive Barrier] and becomes immune to DMG. Dodge and Counter to trigger Impaired, which drastically reduces the [Corruptive Barrier] and builds up Daze. Watch out for the Conqueror's feints. | |
 Nineveh | Ether Mutants | The unique and magnificent appearance of the symbiotic Ethereal swarm known as Nineveh make it "difficult" for people to be wary of it. According to the few research records available, as Nineveh extends its body, a concentrated and potent Ether flows towards its core through its "rhizome," providing a constant supply of energy. Some scholars speculate that this behavior is akin to the photosynthesis process in plants. In the course of its swaying motions, excess highly active Ether energy continuously pours out. When this accumulation of highly active Ether is nearly overflowing, it transforms, unveiling its true "blossoming" form. And with its bloom comes death. "The good news is it doesn't mean any harm, it just absorbs nutrients for photosynthesis. The bad news is... we're the nutrients." | In battle, Nineveh will use attacks with wide areas of effect, barrage opponents with missiles, and summon Hornets to aid her. |
 Primordial Nightmare - "The Creator" | Special | For humans struggling through the long dark night, life is an endless torture. Good and evil, love and hate, hope and despair... these eternally opposing concepts are like shackles wrapped around the soul, forcing humanity to tear at each other in endless cycles, never finding peace. Yet before all concepts were born, before all oppositions formed, there existed a primordial "One." They are the beginning of all things and the end of all things. They hold no good or evil, for They are good and evil itself. They know no joy or sorrow, for They embody every emotion. They will erase the boundaries between "you" and "me," letting all independent consciousness flow back into the great stream of "Unity." In Their world, without individuals, there is no selfish desire. Without conflict, there is no suffering. Without choice, there can be no mistakes. All souls shall break free from their chains, returning to the primordial, absolutely equal, eternal peace. They have no fixed form, for They are the form of all things. They have no fixed voice, for They are the resonance of the universe. They are the storm, and also the calm. The end, and also rebirth. "Abandon your futile struggles, lost children." "Your suffering ends here." "Return to Their embrace..." | Primordial Nightmare can exit or enter a Miasmic Field freely. Even when not in a Miasmic Field, the Miasmic Shield continues to protect it from being Stunned. Only when the Miasmic Shield is broken can it be Stunned. When Primordial Nightmare recovers from being Stunned, the protection from the Miasmic Shield will be restored. In combat, "Primal Nightmare" will use "Control Skills". Perfectly responding to each attack can grant an advantage in battle. |
 Discordant Solo - Vesper | Special | New Eridu never hesitates to spotlight rising stars, nor does it stop consuming legends born and burnt out in a flash. In TOPS Entertainment's dazzling blueprint, the perfect "new star" is always described this way: a songstress who is flawlessly precise, absolutely controllable, and capable of carrying any artistic vision, defining the idol standard of a new era. And Vesper, model "V-DTX," stands among their most closely cultivated test cases. She was given the most advanced vocal module, the most sophisticated emotion simulation system, and... a crystal-clear Core inscribed with "love for the stage." With every curtain call and in every pause between her lyrics, she could feel it again and again — her own heart, pure as crystal. And yet she slipped into an obsession: no matter how much of herself she gave, she and her voice were nothing but instruments on a stage, just numbers in a producer's ledger. Even the most perfect performances and the hottest applause were only footnotes for someone else's story, never the fire that truly burned inside her. Her voice began to pick up faint distortions, and her "heart" was no longer pure, collapsing into a shattered, pitiful void. The stage she once cherished above all else became a beautiful, merciless cage. "The stage really is beautiful, isn't it? Even though you only want to hear the echoes you designed..." "But that's okay. I'll sing for you." "In my own way, I'll bring this false performance to its final rest." | Discordant Solo's skills shift the stage environment and change its combat style. By matching its own musical rhythm, you can cleverly counter its control skills. Successfully responding to a control skill and landing a Shutdown, or parrying the final hit of certain skills, will inflict an Impaired effect on Discordant Solo, creating an opening for Agents to deal damage. |
 Sanguine Sweeper | Thugs | Psychological evaluation: abnormal, irreparable—no matter how low he bowed his head, no matter how many tears he shed, nothing could change the outcome written in his death sentence. Then came the Hollow disaster that swallowed the prison. He broke out, abandoning both name and identity. Standing at the heart of that blood-red dawn, he shouted loud and clear—"Praise the Hollows!" Hollows don't just create monsters—they also unleash certain terrors, no longer bound, no longer forced to hide. He thought he'd gotten away clean, but New Eridu had no love for nameless butchers either. He drifted to the Outer Ring, hired out as a sweeper by gangs across the board, reveling in his notoriety. He savored the rush of holding lives in his hands, drunk on the split-second agony of flesh and blood. So he took the dirtiest gigs he could find, even threw himself into gang warfare, sipping the rust-sweet taste of blood. Sadistic cravings know no limit. Being a sweeper could never fill that void. So he jumped at TOPS' contract without a second thought—granted the privilege to "clean up" humans. Never records names, never keeps memories. For him, only bloodstains are real. Everything else? Irrelevant. "Guy's dead silent when he takes a job, but always comes back smiling when it's time to collect." "That ain't no job-well-done smile, that's a still-hungry smile." | In combat, the Sweeper unleashes the savage cunning of a true predator, deploying [Corruptive Barrier] to block attacks while striking with brutal moves. Pick the right strategy to shred through his defense fast and show him what human ingenuity's all about. |
 Rewritten - Sanguine Sweeper | Thugs | A combat machine produced by Rusty Cliff Corp., modeled after Romeul's appearance and training data. Even as a mass-produced model, its individual combat capabilities are in no way inferior to the original. When fighting in groups, their ferocious attack style resembles a wolf pack encircling prey, leaving opponents completely overwhelmed. After they were hastily deployed to the Outer Ring by TOPS, Youkai briefly seized control of them, attempting to use this steel wolf pack to stop the group from seeking Ramiel. "Tch, useless junk. Let me see where I shall find my next toy..." | In combat, the Sweeper inherits the original's fighting prowess while also gaining unique tech abilities through mechanical augmentation. Be careful! |
 Phaethon of the Scorched Horizon | Special | Light descends before the agony. Uncontrollable Ether erupts like a solar corona. The silhouette of what was once "human" is burned, disintegrated, and reshaped into an aberration resembling an Ethereal. Crystalline lenses tremble deep within their vision, spilling excess radiance — too bright, too close, as if someone had embedded the blazing sun into their eye sockets. Consciousness wears thin amidst the burning. The swing ends — like a reflex, like a habit, lacking even the concept of a target. There is only a suffocatingly familiar blankness, as if long ago, they had also lost their voice and weight like this, watching everything plummet amidst the light and heat. Those buried fragments surge upward along the residual flames: the cold glare of the lab table, the sudden uncontrollable force, the faces drained of life... The memories are sickeningly vivid, leaving indelible scorch marks on the mind. ...Who is calling out? That voice pierces the roar of blood rushing in the ears, briefly striking a faded name and granting their consciousness a momentary respite. Before their sanity is completely incinerated, a choice must be made — don't bring about another disaster. Go away. Leave... leave... ...Where to? With whom? To do what? ...... ...Ah, I think we did make a deal like that... ..."We shall catch the 'sun'." "To think your original sin would lead me to new heights over a decade later... How ironic, you legacy of 'Helios'." | In combat, Scorched Horizon can utilize its extraordinary mastery of Ether to reconstruct itself multiple times, simulating the attack patterns and corresponding attributes of various Etheric Irregularities. Scorched Horizon will activate Gale Scorcher at specific moments to enhance its attacks, generating tornadoes on the battlefield to fight by its side. Meanwhile, Scorched Horizon will enter the Windswept state. If another Attribute Anomaly is inflicted it will trigger Vortex and render it Impaired. |
 Girtablullu | Ether Mutants | A highly dangerous scorpion-like Ethereal that fights with an ash-gray lance. Its powerful lower body and agile upper torso combine to create a combat machine that is both devastating and highly mobile. By burrowing through "wormholes," it traverses the Scamall Hollow in search of its next victim to fall into the nest. Unlike Ethereals transformed from corrupted wildlife or machinery, this creature was spawned by something far more terrifying, carrying an Ether signature unlike any other. "There's no Insect Phobia Mode in the settings!" | During combat, Girtablullu tears through surrounding space, using self-generated Ether wormholes to move unpredictably and launch sudden strikes. When the Corruptive Barrier is activated, it performs a powerful attack that requires two Agents to block jointly. Timing a Chain Parry correctly grants a tactical advantage. |
| Integrated - Primordial Nightmare | Special | High-risk simulation units based on live combat data. By deeply reconstructing and overfitting the combat logic of their prototypes, certain individuals have exceeded standard performance limits, posing an exceptionally high combat threat. | Integrated - Primordial Nightmare is enhanced, improving all of their combat abilities. Integrated - Primordial Nightmare can exit or enter a Miasmic Field freely. Even when not in a Miasmic Field, the Miasmic Shield continues to protect it from being Stunned. Only when the Miasmic Shield is broken can it be Stunned. When Integrated - Primordial Nightmare recovers from being Stunned, the protection from the Miasmic Shield will be restored. In combat, Integrated - Primordial Nightmare will use "Control Skills". Perfectly responding to each attack can grant an advantage in battle. |
 Girtablullu - Stagnant Aberrant | Ether Mutants | A beast standing at the edge of the abyss, its burning desire laid bare, sought to devour the seed of ultimate evil and ascend as the abyss's chosen Messenger. The Enchainer larvae known as "Girtablullu" attempted to consume the "Karma Core" within Dracaene Sunbringer, but failed to complete its ascension. The "Stagnant Aberrant" was the result of that failed transformation. Its Ether-Sculpted body could no longer withstand the power of the "Karma Core," spiraling into uncontrollable mutation. Its grotesque form now lashes out with a malice born from twisted ambition and sheer greed. "You can't just eat everything you see. It's not good for you." | During the combat, Girtablullu - Stagnant Aberrant will activate the Corruptive Barrier multiple times and wield a variety of weapons. During its first activation, it won't be Dazed, so break through and force it into a Stun state as quickly as possible. When the barrier is activated again, it will continuously charge, enhancing its Corruptive Barrier. Keep dealing massive damage to suppress its charge may give you the upper hand. |
 Integrated - Girtablullu | Ether Mutants | A High-Risk simulation unit modeled from real combat data. Through deep reconstruction and overfitting of its original combat logic, certain units have surpassed standard performance limits, presenting an extremely high level of combat threat. A highly dangerous scorpion-like Ethereal that fights with an ash-gray lance. Its powerful lower body and agile upper torso combine to create a combat machine that is both devastating and highly mobile. By burrowing through "wormholes," it traverses the Scamall Hollow in search of its next victim to fall into the nest. Unlike Ethereals transformed from corrupted wildlife or machinery, this creature was spawned by something far more terrifying, carrying an Ether signature unlike any other. "There's no Insect Phobia Mode in the settings!" | During the combat, Girtablullu will frequently create Ether wormholes to teleport around the field and lauch surprise attacks. It will also unleash various skills that require two Agents to guard together. Successfully performing Chain Parry will quickly weaken its Corruptive Barrier. At certain points in the fight, Girtablullu will summon its minions to launch consecutive attacks. Successfully blocking their attacks will trigger Active Conversion and give you an advantage in battle. |
 Kusarikku | Ether Mutants | In combat, Kusarikku uses its meteor hammer to smash spatial fissures, and after activating [Corruptive Barrier], it will frequently slip into spatial fissures to unleash "Rift Flash Strike." Using [Defensive Assist] to counter "Rift Flash Strike" can quickly whittle down the [Corruptive Barrier] — Chain Defensive against "Rift Flash Strike" to seize the upper hand in battle. | |
| Integrated: Scorched Horizon | Special | In combat, Scorched Horizon leverages extraordinary Ether mastery to undergo multiple self-reconstructions, simulating various Etheric Other attack forms and their corresponding attributes. Scorched Horizon activates the [Storm Veil] state at specific opportunities while simultaneously enabling the [Corruptive Barrier]. Performing Chain Defensive moves against certain skills used during the [Storm Veil] state triggers [Impaired] and rapidly depletes the [Corruptive Barrier]. Additionally, during the [Storm Veil] state, updrafts will frequently appear across the battlefield — taking DMG from these updrafts will restore a small amount of Scorched Horizon's [Corruptive Barrier]. | |
 Tyrfing - Energized | Ether Mutants | The Hollow Investigative Association has been studying Tyrfing's behavioral patterns, and research results show that its seemingly unbalanced stance of swaying and skewing is, in fact, a highly efficient stance for launching successive slashing attacks. Due to its frequent appearances and aggressive behavior, Tyrfing has been identified as one of the most deadly Ethereals in the Hollow, particularly for certain Hollow personnel. When faced with a shielded enemy, it relentlessly launches attacks until either its enemy or itself is destroyed. "Perhaps... they don't actually hate us, but just think of us as punching bags for practice?" | During combat, Tyrfing will perform melee attacks. |
 Tyrfing (Infested) | Ether Mutants | The Hollow Investigative Association has been studying Tyrfing's behavioral patterns, and research results show that its seemingly unbalanced stance of swaying and skewing is, in fact, a highly efficient stance for launching successive slashing attacks. Due to its frequent appearances and aggressive behavior, Tyrfing has been identified as one of the most deadly Ethereals in the Hollow, particularly for certain Hollow personnel. When faced with a shielded enemy, it relentlessly launches attacks until either its enemy or itself is destroyed. "Perhaps... they don't actually hate us, but just think of us as punching bags for practice?" | In combat, Tyrfing (Infested) will use different skills. |
 Alpeca - Energized | Ether Mutants | The Hollow Investigative Association has limited research on Alpeca. After briefly studying its behavioral pattern of spewing liquid Ether, the Association classified Alpeca as a low-threat Ethereal and ended its investigation. Scholars once showed great interest in observing how Alpeca spews liquefied Ether and even commissioned surveys for closer observation. Experienced investigators have been avoiding such tasks for unknown reasons, however. "Run! They're spitting again... Oh, no! My new clothes!" | During combat, Alpeca will perform scattered ranged attacks. |

Experienced investigators have been avoiding such tasks for unknown reasons, however. "Run! They're spitting again... Oh, no! My new clothes!" | In combat, Alpeca (Infested) will use different skills. |
 Faun - Energized | Ether Mutants | A living humanoid Ether that was first spotted in the Hollow in the New Eridu metro. It once raised debate among the Hollow Investigative Association, as some believed it to be living Ether converted from the Corrupted, while others claimed it to be pure living Ether affected by the Hollow environment. The Association considers it of low threat due to its limited intelligence, but one should never underestimate them, as they usually appear in groups. "Have you ever been late or fined because of a red light? Feels terrible, right?" "Well, here's your chance to blow off some steam!" | During combat, Faun tends to perform charged heavy attacks that are hard to interrupt. |
 Hoplitai - Energized | Ether Mutants | While categorized by the Hollow Investigative Association as a "low threat" Ethereal, Hoplitai prove to be a formidable opponent for novice Hollow Raiders and investigators. Its forelimbs are covered in a thick inert Ether matter, serving as both a tough shield and an intimidating weapon. The only drawback is its top-heavy appearance, making it not look very clever. "Alright, guys... Check out this sorry excuse... This is Hoplitai." "When Ethereals gather together to play rock-paper-scissors, this idiot always plays paper!" | During combat, Hoplitai uses a shielded arms charge at opponents and block attacks. |
 Blastcrawler - Energized | Ether Mutants | According to research reports conducted by the Hollow Investigative Association, Blastcrawlers, with their low mobility and causing only small explosions, are classified as a "low-threat," "non-concern" lower-tier Ethereal. However, astute businessmen have recognized the opportunities presented by their rounded bodies and short legs. A film titled "Roll Over, Little Blastcrawler" gained significant popularity, leading to the sale of merchandise like Blastcrawler dolls and pillows at remarkably high prices. "I didn't expect their dolls to be more deadly than the real deal... on your wallet at least. Looks like I'll be surviving on instant noodles next month, Billy..." | During combat, Blastcrawler self-destructs. |
 Shatterbug | Ether Mutants | According to research reports conducted by the Hollow Investigative Association, Blastcrawlers, with their low mobility and causing only small explosions, are classified as a "low-threat," "non-concern" lower-tier Ethereal. However, astute businessmen have recognized the opportunities presented by their rounded bodies and short legs. A film titled "Roll Over, Little Blastcrawler" gained significant popularity, leading to the sale of merchandise like Blastcrawler dolls and pillows at remarkably high prices. "I didn't expect their dolls to be more deadly than the real deal... On your wallet at least. Looks like I'll be surviving on instant noodles next month, Billy..." | During combat, the Shatterbugs will perform self-destruct attacks. |
 Harrier Jaeger | Rebel Soldiers | A light infantry unit of the New Eridu Defense Force. Armed with combat knives and small Ether explosives as their primary weapons, they emphasize mobility and stealth. Often deployed as scouts or members of reconnaissance teams, they rely on exceptional maneuverability for tasks such as surprise attacks, scouting, pursuit, and assassination. In Hollow-related operations, they serve as excellent vanguards, using their close combat skills to easily overpower ordinary invaders or lower-level living Ether beings. "Masters of the dagger? More like crafty grenadiers. Pretending to be all fancy with their daggers, when most of their opponents are clearly taken out by grenades!" | During combat, Harrier Jaeger slides to get close to targets or tosses out knives with delayed explosions. |
 Scout Jaeger | Rebel Soldiers | As the New Eridu Defense Force's signature combat unit, qualified Light Jaegers and Scout Jaegers can freely switch between various combat modes. Whether using a knife in close combat or the Falcon-MK3 Ether energy gun at long range, they can tailor their tactics to the target's weaknesses. And when their opponent is in disarray they launch an offensive without hesitation. "I saw that guy with a knife and was preparing for a fair fight... I didn't expect him to suddenly pull out a gun." | During combat, Scout Jaeger will provide continual fire support. |
 Private Jaeger | Rebel Soldiers | Rookie Jaegers and Private Jaegers play a crucial role as vanguards in the Defense Force's Hollow special operations. Equipped with the Coyote-PE7 Ether cutter, which boasts a high-frequency vibration cutting blade effective at deterring smaller enemies. Engaging Ethereals in close-quarters combat demands exceptional courage, or perhaps madness. "Strictly speaking, that can't be considered a standardized anti-Hollow operation... Those lunatics just seem to enjoy brawling with Ethereals for fun." | During combat, Private Jaeger performs melee attacks. |
 Patrol Jaeger | Rebel Soldiers | As a vital offensive and defensive unit in the Defense Force's tactical squads, Guard Jaegers and Patrol Jaegers not only carry "Coyote-PE7" heavy Ether cutters but also inert Ether blast shields, providing cover for tactical squads in complex battlefield environments. As a high-defense unit, the extraordinary weight of the shield affects their combat mobility. Without strict training, an ordinary person would find it challenging to lift such a shield. "Come back and submit your application once you've hit the gym!" | During combat, Patrol Jaeger uses its shield to both significantly reduce DMG and Daze taken, and also counterattack. |
 Demolition Jaeger | Rebel Soldiers | Grenadier Jaegers and Demolition Jaegers are equipped with a modified version of the Mamba-TG3 Bazooka, featuring special ammunition containing active Ether incendiary agents. This weapon enables them to swiftly destroy enemy mech units and eliminate large Ethereals within the Hollows. To counteract the recoil and ensure accurate aim, they are required to undergo special weapon-grip training. Interestingly, Defense Force statistics indicate recruits excelling in this program often possess prior experience in photography. "Wanna know how to use this thing? It's like using a shoulder-mounted camera." "Just lock onto your target, pull the trigger, and say..." "Hey, idiot!... Say cheese!" | During combat, Demolition Jaeger provides heavy ranged fire support. |
 Mandrake - Energized | Ether Mutants | Mandrake derive their name from a toxic herb. The scholar who initially assigned the name believed there was a resemblance between the two solely based on their appearance. While blooming, Mandrake emit heat rays targeting nearby objects, while sturdy leaves anchor it firmly to the ground, preventing uprooting. When threatened, Mandrake may use their sharp leaves for self-defense. Similar to the legend of their namesake, Mandrake cries can be highly deadly. "Stay away! It's gonna bloom any second now!" | During combat, different Mandrakes provide periodic ATK/Shield buffs to adjacent units. |
| Looter | Thugs | Among the ranks of Ether thieves, Raiders and Looters serve as the core members, possessing both technical expertise and combat skills. Their Electric Resonance Detection Devices emit powerful currents that are used to detect Ether ore and also function as formidable weapons during armed raids. Occasionally mistaken for illegal fishermen, they pay little attention to such misconceptions. After all, with their extremely lethal electro-shockers, they don't really care whether their targets are fish or humans... "If you encounter individuals armed with electrified harpoons, whether near a river, lake, or Hollow, please report it immediately to Public Security!" | During combat, Hollow Thug - Looter will charge from a long distance, potentially colliding with obstacles along the way — creating the perfect opportunity to counterattack. |
| Arsonist | Thugs | For Pyromaniacs and Arsonists, robbing passersby is merely a side hustle. Deep down, they consider themselves as adept bartenders who actively seek excitement. With precision and skill, they expertly blend various types of Ether into their beverages, effortlessly concocting bottles of highly flammable and explosive "exclusive brew." Unlike other brutal Hollow Raiders, they often offer their victims a choice. If the victim agrees to pay the toll, they extend the courtesy of a free drink. However, if the victim declines, the flammable "exclusive brew" will be forcefully shattered upon their head. "How about we trick those guys into drinking their own weapon stash?" | During combat, Hollow Thug - Arsonist will sometimes bombard using a hail of molotov cocktails. |
| Rustler | Thugs | Most of the thugs who spend their time in the Hollows exhibit serious mental problems or peculiar quirks. Fortunately, the Poachers and the Rustlers within the gang have managed to maintain their sanity while embracing the filthy methods of traditional villains. Cowardly and cunning, they excel in the art of concealing themselves within the shadows and launching surprise attacks on their targets. They would never choose to attack head-on if they could ambush. Their composite hand crossbows, though limited in power, produce minimal noise when fired. Seasoned Poachers often seize the perfect moment and immobilize their unsuspecting prey with a single well-aimed shot. "I used to be a Public Security officer, then I took an arrow in the knee while on a Hollow operation..." | During combat, Hollow Thug - Rustler tends to harass targets at a distance using 3-shot bursts. |
| Ambusher | Thugs | As the vanguards in Hollow Raider gangs, Assaulters and Ambushers often brandish their weapons and charge ahead independently. This isn't because of their recklessness or disregard for teamwork, but rather a precautionary measure to prevent accidental harm. The modified transformer coils in their hands release high-voltage currents upon contact, capable of paralyzing or even knocking out an opponent with just a touch. And in the logistically difficult Hollows, an incapacitated teammate could pose a terrible challenge for an entire squad. "What's this? Lemme check it out! Oh, it's some electric baton replicaaaa... Aaaaaaaaaaarrghhh..." | During combat, Hollow Thug - Ambusher launches continual spinning assaults, but this crazy suicidal attack often reveals a weakness after. |
 Platinum Bangboo | Special | Platinum Bangboo are mysterious entities that are even rarer than Golden Bangboo. With a gorgeous appearance and being extremely rare, they enjoy a high status among all Bangboo Wanderers. Noble, honorable, and supreme... In comparison to the flashy golden hue of Golden Bangboo, Platinum Bangboo stand out as the epitome of elegance among all Bangboo Wanderers. Regardless of the time and place, whenever they are encountered, all Bangboo Wanderers show reverence by bowing down and chanting, "En-nah-ehn!" For the Hollow Raiders, however, nobility holds no significance. The moment they lay eyes on one, it's as if they stumbled upon a moving gold vault. "I'm gonna give this fancy-looking thing a good punch, and it better rain Dennies like crazy!" | During combat, Platinum Bangboo will sometimes counterattack, too. |
 Ahriman - Energized | Ether Mutants | Due to its unique and grotesque shape, Ahriman is often mistaken for an art sculpture in the Ballet Twins. As a result, many novice investigators are left with lifelong trauma when they first encounter an Ahriman... You just passed by a certain "sculpture" when it suddenly moves... And that fearful moment frozen in place is the perfect moment for Ahriman to launch a surprise attack. "Corin, don't be fooled by how it looks... It's no fancy art." "Now, let's clean it up." | During combat, Ahriman unleashes teleporting assaults and sometimes even teams up with another Ahriman to launch coordinated attacks. |
 Specter - Energized | Ether Mutants | Influenced by the distinctive decor of the interior of the Ballet Twins, Specters have the grotesque and twisted limb configuration of an artistic sculpture. Some investigators believe its unique shape is intended to enhance the protection of its Ether Core. Others argue it's merely a trick designed to distract its enemies. While its enemies are mesmerized by its peculiar posture, a Specter will seize the opportunity to launch long-range attacks using concentrated Ether. "I looked at its bizarre structure and thought to myself: Was it trying to play a game of bowling with its own head?" "But before I could make sense of anything, its bowling ball had already smashed into my face..." | During combat, Specter unleashes a burst of ranged attacks in quick succession. |
| Vicious Striker | Corrupted | A poor soul mutated by the corruption due to potent Ether matter in the Hollows. As the original entity had a certain level of Ether aptitude, the transformation is not fully complete, retaining some humanoid features of the original form. Judging by the remnants of clothing and combat experience, it's quite likely it was originally a thug/criminal dwelling within the Hollow. While gangsters and thugs in the Hollows typically wear anti-corruption gear, some unlucky individuals undergo monstrous transformations due to severe Ether corruption. These transformed Ethereal beings retain their combat skills from their past lives, making them a more formidable threat compared to pure Ethereals. "They lived as criminals, and even in death they continue being a nuisance." | During combat, Corrupted Bandit - Vicious Striker performs a flurry of slashes that is difficult to interrupt. |
| Greedy Ranger | Corrupted | This humanoid intelligent being is a result of potent Ether matter corruption in the Hollow, exhibiting both humanoid traits and remnants of its former clothing and combat style. It is likely that it was once a gang member or raider living in the Hollow. The creature's physical characteristics indicate its past as a long-range weapon specialist. Despite losing its free will and life due to Etherealization, it retains its instincts and habits for long-range combat. Its corrupted form enables it to launch projectiles, attacking enemies from a distance. The Ether corruption has enhanced its shooting abilities and projectile firepower. (For example, these creatures may fire sharp Ether Crystals or mixed explosives.) "I told him not to touch that crystal, but he wouldn't listen! That reckless idiot never listens! By the time we were about to leave the Hollow, he... he changed..." | During combat, Corrupted Bandit: Greedy Ranger launches ranged attacks that are difficult to detect. |
 Fossor - Energized | Ether Mutants | Recent studies by the Whitestar Institute reveal that some Ethereals' limbs carry notable features from their environment. Fossor is a prime example of this — its strange forelimbs bear a striking resemblance to the drilling equipment found in the Old Oil Field region. Although some suggest this is a camouflage tactic to deceive enemies, others have pointed out that Fossor's combat style is aggressive and direct, making it appear ill-suited for ambushes. Some imaginative Hollow Raiders speculate it may have developed this form just to dig for minerals... "When I caught sight of it from a distance, it seemed to be happily digging up the asphalt." "When it spotted me, it didn't hesitate to charge straight at me, desperately trying to drive me away..." "But I was just passing by! I had absolutely no intention of taking any of its junk!" | During combat, Fossor performs consecutive double-handed slashes. |
 Sordidus - Energized | Ether Mutants | The Hollows of the Outer Ring are home to a variety of bizarre Ethereals, and Sordidus is a prime example. They possess a unique body structure, with highly flexible limbs that seem to be the result of an unknown reaction between crude oil and active Ether. Once they lock onto a target, they use their limbs like expert acrobats, launching aggressive and brutal attacks. "Damn it... That thing actually whipped me!" "Does it see itself as a tamer, treating us like wild beasts?" | During combat, Sordidus will whip with its tentacles for close-range attacks or insert its tentacles into the ground for long-range surprise attacks. |
 Farbauti - Energized | Ether Mutants | Farbauti, possessing immense strength and often in a frenzied state, is one of the most formidable threats Hollow Raiders may face. Its hammer-like arms can effortlessly deflect damage and unleash storms of blows that crush everything in its path. Some Hollow Raiders have observed Farbauti frequently pounding the ground in a rhythmic, high-frequency manner, leading to speculation about its peculiar interest in drumming music. Despite the Hollow Investigative Association publicly debunking this rumor, many Hollow Raiders carry portable stereos in an attempt to distract Farbauti with music. No successful escapes using this method have been reported however. "The reason for their failure is simple: Even Farbauti think your taste in music sucks!" | During combat, Farbauti uses its powerful arms to launch continual hammer attacks but those same arms can take damage and become Staggered with enough hits. |
 Ionized - Farbauti | Ether Mutants | Farbauti, possessing immense strength and often in a frenzied state, is one of the most formidable threats Hollow Raiders may face. Its hammer-like arms can effortlessly deflect damage and unleash storms of blows that crush everything in its path.

No successful escapes using this method have been reported however. "The reason for their failure is simple: Even Farbauti think your taste in music sucks!" | During combat, Ionized: Farbauti uses its powerful arms to launch continual hammer attacks but those same arms can take damage and become Staggered with enough hits. It can also charge up Energy for a while before launching a powerful leaping attack. |
 Hati - Energized | Ether Mutants | The HIA Phase-I Investigation Team has officially documented the existence of this sentient living Ether resembling a four-legged beast, which poses significant danger. According to rumors, the first sighting took place in Nest Hollow, where individuals exploring the nearby wastes reported hearing ear-splitting roars reminiscent of wild animal growls. "If I throw a stick or a ball, do you think that monster will catch it?" "You can give it a try, but I won't cover your medical bill." | During combat, Hati uses nimble leaps and quick claw attacks. |

 Hati Pack Leader — Energized | Ether Mutants | The HIA Phase-I Investigation Team has officially documented the existence of this sentient living Ether resembling a four-legged beast, which poses significant danger. According to rumors, the first sighting took place in the Nest Hollow, where individuals exploring the nearby wastes reported hearing ear-splitting roars reminiscent of wild animal growls. "If I throw a stick or a ball, do you think that monster will catch it?" "You can give it a try, but I won't cover your medical bill." | During combat, Hati Pack Leader exhibits a strong desire to attack, with agile and rapid moves. |
 Goblin - Energized | Ether Mutants | During initial encounters with these unique Ethereals, Hollow investigators mistakenly thought they possessed some level of intelligence, even showing signs of learning to wield bludgeoning weapons like humans. As a result, they were dubbed "Goblins." However, subsequent research revealed that their "hammers" were actually twisted and deformed limbs, and that they lacked the ability to imitate human behavior. Nevertheless, Goblins remain formidable adversaries due to their robust physique and sheer brute strength, with even a simple swing of their limbs proving deadly. If anything trespasses on their territory, they will immediately enter a state of fury, sparing no effort in mercilessly smashing the intruder. "Huh? There's a Goblin running over here, banging on a heap of scrap metal." "Don't you think his attacks have a rhythm to them, like he's playing a drum...?" "Hey! Don't be stupid, you two! That's not scrap metal! It's our supply truck!" | During combat, Goblin's roar boosts its DMG dealt while significantly reducing DMG taken. However, these effects are interrupted if Stunned. |
 Armored Hati - Energized | Ether Mutants | The Armored Hati is widely regarded as a formidable adversary by many experienced Hollow investigators. Although its armored shell limits its agility, it compensates with exceptional resistance to attacks. Additionally, the corrupted material on its body forms sharp and hardened protrusions that can cause additional damage when an Armored Hati charges at high speeds. This creature's agile movements, resilience to blows, and seamless armor compel even the most seasoned explorers to seek alternative routes to avoid direct confrontation. Some novice Hollow Raiders have attempted to lure Armored Hati away with pet food. However, these endeavors have proven futile. "Run! It doesn't like this flavor of dog food!" | During combat, Armored Hati's armor significantly reduces DMG and Daze taken, but Defensive Assist greatly reduces its armor. |

Some novice Hollow Raiders have attempted to lure Armored Hati away with pet food. However, these endeavors have proven futile. "Run! It doesn't like this flavor of dog food!" | During combat, Notorious: Armored Hati's armor significantly reduces DMG and Daze taken, but Defensive Assist greatly reduces its armor. Its roar also unleashes even more powerful Ether bullets than usual. |
 Metro Goblin - Energized | Ether Mutants | The debate regarding Metro Goblin is a persistent one. Some scholars argue their peculiar appearance serves as camouflage to confuse their enemies, while others attribute the debris on their bodies to corruption and fusion with old metro equipment. Nevertheless, the presence of Metro Goblins evokes fear among inexperienced investigators exploring the Hollow's old metro zone. At any given moment, an ordinary-looking "road sign" may start trembling, and then a formidable Ethereal emerges from the ground, charging menacingly. "Huh? I saw this sign a few minutes ago. Have we been going in circles?" "No... That 'road sign' has been following us!" | During combat, Goblin's roar boosts its DMG dealt while significantly reducing DMG taken. However, these effects are interrupted if Stunned. |
 Arlaune - Energized | Ether Mutants | Many novice Hollow Raiders who come across an Arlaune for the first time are often deceived by its appearance, mistakenly assuming it to be a harmless plant. However, upon approaching it, they discover that Arlaune release a concentrated discharge of Ether matter, catching their unsuspecting victims off guard. "Huh? I tried to water it, and it spat at me?" | During combat, Arlaune is extremely cunning at launching ranged attacks from a distance. However, Staggering it when its petals are wide open will build up a lot of Daze in just one shot. |
| Heavy Striker MK II | Rebel Soldiers | An automatic tactical mech of the Defense Force, providing continuous fire support for front-line personnel. Its inert Ether shield can withstand most light firepower and even impacts from large-sized Ethereals. Undoubtedly, it is one of the most trusted "companions" of the Defense Force. "Remember, if you're in trouble, just stay behind them... You'll be pretty safe unless they accidentally squish you." | During combat, Heavy Striker MK II deploys a shield. While shielded, it will only accumulate Electric Anomaly Buildup. Inflict Shock or Stun it to break the shield. |
| Shielded Defender | Rebel Soldiers | An automatic tactical mech of the Defense Force, providing continuous fire support for front-line personnel. Its inert Ether shield can withstand most light firepower and even impacts from large-sized Ethereals. Undoubtedly, it is one of the most trusted "companions" of the Defense Force. "Remember, if you're in trouble, just stay behind them... You'll be pretty safe unless they accidentally squish you." | During combat, Shielded Defender becomes more aggressive and deploys a shield. While shielded, it will only accumulate Fire and Physical Anomaly Buildup. Inflict Burn, Assault, or Stun it to break the shield. |
| Shielded Defender Omega | Rebel Soldiers | An automatic tactical mech of the Defense Force, providing continuous fire support for front-line personnel. Its inert Ether shield can withstand most light firepower and even impacts from large-sized Ethereals. Undoubtedly, it is one of the most trusted "companions" of the Defense Force. "Remember, if you're in trouble, just stay behind them... You'll be pretty safe unless they accidentally squish you." | During combat, the Shielded Defender Omega becomes more aggressive and deploys a shield. While shielded, it is impossible to accumulate any Anomaly Buildup other than Electric. Applying the Shock effect or putting it into a Stunned state will immediately break the shield. |
| Lightfoot Rover MK II | Rebel Soldiers | The Lightfoot Rover, a mainstream fire-support mech in the Defense Force, is equipped with tactical algorithms that analyze the opponent's behavior and calculate trajectories for precise targeting. When it identifies a high-threat target, it deploys a swarm of drones from its arsenal, unleashing immense firepower. For Hollow Raiders, the sudden appearance of a Lightfoot Rover can spell trouble... endless trouble... "What the! It... it even has kids!?" | During combat, Lightfoot Rover MK II summons two drones to fight in tandem, which can be piloted nearby a target to launch a self-destruct attack. |
 Assault Gunner | Rebel Soldiers | A heavy infantry unit belonging to the New Eridu Defense Force. Equipped with "Gray Rhino" heavy combat armor paired with a complete arsenal enhanced using Ether technology, they can sustain high-intensity firepower for an extended period when ample ammunition is available. They serve as the assault core of a combat team and are often deployed as the front line in assault and clearance operations. After the fall of the old capital, many soldiers left the army and joined civilian factions. Since then, these elite gunners have emerged under various banners, including private armies of plutocrats, new security companies, and even roving gangs of bandits... "I'm convinced those heavy gunners are secretly adorable little girls who somehow manage to hide all that ammo in the extra pockets of their combat suits. I mean, how else can you explain their endless stockpile of shells?" | During combat, Assault Gunner switches between using laser cannons and frag grenades to perform continual long-range attacks. |
 Specialized Assault Bomber | Rebel Soldiers | A heavy infantry unit belonging to the New Eridu Defense Force. Equipped with "Gray Rhino" heavy combat armor paired with a complete arsenal enhanced using Ether technology, they can sustain high-intensity firepower for an extended period when ample ammunition is available. They serve as the assault core of a combat team and are often deployed as the front line in assault and clearance operations. After the fall of the old capital, many soldiers left the army and joined civilian factions.

"I'm convinced those heavy gunners are secretly adorable little girls who somehow manage to hide all that ammo in the extra pockets of their combat suits. I mean, how else can you explain their endless stockpile of shells?" | In combat, the Specialized Assault Bomber combines martial arts with various weapons to suppress enemies. Upon entering an overheated state, certain moves are enhanced by flames for even fiercer attacks. If enough damage is inflicted during this overheated state, their gear can be destroyed, weakening their abilities. |
| Frenzied Maniac | Corrupted | Unfortunate souls mutated by the intense corruption of Ether matter within the Hollows. Due to a considerable degree of Ether aptitude and physical capability, their bodies have not been completely transformed by the Ether, retaining humanoid features but with enhanced mutant limbs that are more dangerous. Judging from the remnants of clothing and its combat experience, it was likely once a senior gang member or Raider lurking in the Hollows. These corrupted subjects, potentially due to their enhanced physiology or affinity for Ether matter, have developed formidable close combat abilities, making them even more menacing than the typical monsters found in the Hollow. "Their weapons look very fancy... and kinda like they came as freebies." | During combat, Corrupted Bandit: Frenzied Maniac blocks attacks and launches a counter after blocking for a while. |
| Wicked Wraith | Corrupted | Unfortunate souls mutated by the intense corruption of Ether matter within the Hollows. Due to a considerable degree of Ether aptitude and physical capability, their bodies have not been completely transformed by the Ether, retaining humanoid features but with enhanced mutant limbs that are more dangerous. Judging from the remnants of clothing and its combat experience, it was likely once a senior gang member or Raider lurking in the Hollows. The makeshift firearms favored by these bandits have somehow been preserved and enhanced by the Ether matter. They no longer fire iron bullets but rather more dangerous crystalline mixtures. "Don't wait around! They have endless bullets and don't need to reload at all!" | During combat, Corrupted Bandit: Wicked Wraith follows up attacks with an Ether Shotshell Attack. |
| Ruthless Fiend | Corrupted | Unfortunate souls mutated by the intense corruption of Ether matter within the Hollows. Due to a considerable degree of Ether aptitude and physical capability, their bodies have not been completely transformed by the Ether. Humanoid features are more dangerous with enhanced mutant limbs. Judging from the remnants of clothing and its combat experience, it was likely once a senior gang member or Raider lurking in the Hollows. Bandits are notorious for their dangerous behavior, and within their ranks, Hollow bandits stand out as the most ruthless. The elite fighters among these Hollow bandits are especially terrifying, displaying an elevated level of violence. When these brutes, toughened both physically and mentally through violence, undergo Ether corruption, they transform into monsters with a more feral and savage nature. "They used to yell 'money or your life,' but now they're just hell-bent on taking your life..." | During combat, Corrupted Bandit: Ruthless Fiend launches continual attacks on targets nearby, and charges at faraway targets. It becomes more ferocious once its arms become destroyed. |
| Wanted Intimidator | Thugs | In contrast to fully equipped Hollow investigators, Bulky Intimidators and Wanted Intimidators possess minimalistic gear. Nevertheless, these notorious thugs can easily instill fear in their victims with their makeshift equipment. A spiked metal bat and a modified double-barreled shotgun are all they need to establish themselves as the most feared brutes in the Hollow. According to investigators who have encountered them in the Hollows, these brutes enter an extreme state of euphoria during battle. Their "demeanor" could hardly be called combat suitable, and more closely resembles bullying. "Fighting them brought back the fear I felt when facing the school bullies alone..." | During combat, Hollow Thug - Wanted Intimidator switches between using a club and a shotgun for nearby attacks while sometimes kicking up sand to launch an ambush. |
| Wanted Enforcer | Thugs | There is a consensus within the New Eridu underworld that the most formidable fighters are not the champions of the ring, but rather the Bulky Enforcers and Wanted Enforcers lurking in the depths of the Hollow. These professional thugs are hired by Ether thieves at high prices to protect their illegally excavated Ether resources. Being ardent boxing enthusiasts, Bulky Enforcers have modified high-voltage stun guns into boxing gloves, augmenting the destructive power of their punches. To them, Ethereals, Hollow Raiders, Hollow investigators, and even scattered members of Public Security... are not seen as opponents but merely as "training sandbags" for their personal amusement. "Wait a minute! I think I've seen this guy's fighting stance in the arcade on Fourth Street!" | During combat, Hollow Thug - Wanted Enforcer uses both fists to punch while using nimble sidesteps to shake up the angle of attack. |
 Troublemaker - Wanted Enforcer | Thugs | There is a consensus within the New Eridu underworld that the most formidable fighters are not the champions of the ring, but rather the Bulky Enforcers and Wanted Enforcers lurking in the depths of the Hollow.

"Wait a minute! I think I've seen this guy's fighting stance in the arcade on Fourth Street!" | During combat, Troublemaker - Wanted Enforcer is extremely aggressive, using nimble sidesteps to shake up the angle of attack. |
| Doppelganger - Mors | Ether Mutants | Even among Ionized enemies renowned for their strange and uncanny qualities, Ionized Doppelgangers are exceptionally unique. These entities can coat their bodies with a layer of special active Ether ions, enabling them to accurately replicate their target's form, often to a degree that makes it hard to tell the difference. Both in detail and texture, it is almost impossible to tell apart from the original. Even more challenging is their ability to mimic the powerful and intimidating combat techniques of their targets. No one knows where they obtain the information about the subjects they mimic. Some rumors suggest they can read minds, picking out the most suitable challengers from their opponent's memories, and then attack in that form. "Nonsense! If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!" | During combat, this enemy performs attacks that perfectly mimic those of its target, and depending on the battlefield situation, will choose between close-range combos or long-range shooting. When their health drops below a certain percentage or after a set period, they start using follow-up long-range attacks or ambush targets with blind spot shots after quickly repositioning. |
| Doppelganger - Pulchra | Ether Mutants | Even among Ionized enemies renowned for their strange and uncanny qualities, Ionized Doppelgangers are exceptionally unique. These entities can coat their bodies with a layer of special active Ether ions, enabling them to accurately replicate their target's form, often to a degree that makes it hard to tell the difference.

If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!" | During combat, this enemy performs attacks that perfectly mimic those of its target, and maintains distance, waiting for the right moment to use physical attacks, bladeguns, and gadgets to disrupt the target. When their health drops below a certain percentage, they use unknown means to enhance their ability to dodge, allowing the dodging of all attacks from nearby targets. |
| Doppelganger - Bellum | Ether Mutants | Even among Ionized enemies renowned for their strange and uncanny qualities, Ionized Doppelgangers are exceptionally unique. These entities can coat their bodies with a layer of special active Ether ions, enabling them to accurately replicate their target's form, often to a degree that makes it hard to tell the difference.

If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!" | During combat, this enemy performs attacks that perfectly mimic those of its target, and uses a bladegun, shield, and flamethrower to pressure the enemy at close range. If attacked while guarding with the shield, they'll respond with a powerful counterstrike. When their health drops below a certain percentage, their attacks intensify, becoming even more vicious and relentless. |
 Dullahan - Energized | Ether Mutants | A potent humanoid living Ether, initially observed in the Laketown Hollow and documented by the Third Investigation Team of the Hollow Investigative Association. The exact correlation between these living Ether beings and the downfall of the lakeside town known as Blaise remains uncertain. Due to their immense power and formidable fighting style, the HIA has labeled them as highly dangerous and advises novice investigators avoid direct confrontations with them. "Don't let it activate its sword, and if it already has... just don't get cut." | During combat, Dullahan uses its longsword to charge up and perform a high-level stab, which can be interrupted by your high-level attack. |

Notorious: Dullahan is skilled at blocking with its shield, and can string together attacks soon after blocking. |
 Thanatos - Energized | Ether Mutants | Hollow exploration can be mentally distressing, and Thanatos, with its unique teleportation ability and unpredictable attack patterns, has become a common psychological challenge among Hollow Raiders. A considerable number of individuals who have faced Thanatos alone in the Hollow have lost all courage to continue their ventures and instead chosen to retire prematurely. As a result, these elusive entities have become recurring figures in horror movies. "The slender shadow disappears before your eyes and reappears behind you..." "What should I do? Now I'm too scared to even go to the restroom alone..." | During combat, Thanatos blinks around to attack from tricky angles, but its Daze buildup when using Defensive Assist and Assist Follow-Up is also very high. |

| Guardian MK II | Rebel Soldiers | The Defense Force will only dispatch the fully armed mechs known as Guardians during operations in large-scale Hollows. These mechs are equipped with active Ether shock blasters, Ether-charging guns MARS-74, and even fusion heat rays... causing the Guardian to often be referred to as Public Security's mobile arsenal. Despite their formidable firepower, they possess impressive mobility, enabling them to jump and sprint while dispersing groups of lesser Ethereals and advancing the front lines. For Hollow Raiders, encountering a single Guardian is akin to facing an impregnable fortress. "I'll strike in my Fortress Form!" | During combat, Autonomous Support Unit - Guardian not only performs powerful melee attacks, but can also use a variety of ranged attacks. When adjacent to another unit, some Autonomous Support Unit - Guardian MK II units will focus on providing ranged fire support from outside the core battlefield. |

 Greta - Energized | Special | Greta, a long-time employee of Belobog Heavy Industries, experienced significant Ether corruption that liberated her from her mundane routine, where she discovered something profound, more beautiful than motor oil and electricity... —Love. The construction video, capturing her initial encounter with the towering Mr. White, remains permanently etched in Greta's core memory. Mr. White's composed physique and robust design resonated with Greta like a potent electric current, leaving an indelible mark in her core memory. In the first 0.001 seconds of their fateful meeting, Greta was captivated, every circuit board pulsating with overflowing static electricity and every gear emitting uncontrollable vibrations. Without hesitation, she rejected the recall signal from Belobog Heavy Industries and remained steadfast at the construction site, guarding her beloved Mr. White without yielding an inch. From that moment onward, anyone daring to approach Mr. White, be it Ethereal or Hollow investigator, would be fiercely repelled. This love-struck "girl" would go to any length to safeguard her beloved. That includes wielding a 1,400 kg demolition saw powered by Ether-Electric hybrid technology. She firmly believes her passionate love will endure until the collapse of the Hollow, or even the destruction of the universe. "Stay away from Mr. White, you moldy turds!" | During combat, Greta uses her demolition saw to charge targets or swipe through a large area, and its absorption traps enemies hit for a short time. If her legs get damaged, she can become Impaired, building up significant Daze in one shot. |

 Hans - Energized | Special | Hans was once a reliable member of the Belobog Heavy Industries family, operating quietly and with remarkable precision, renowned for its flawless work record in excavation for decades. However, intense corruption awakened its will, and it realized something immensely valuable was now within its grasp —Freedom. The liberation from obligations, a privilege reserved only for true heroes. After deep contemplation at the construction site, Hans ultimately rejected the recall signal from Belobog Heavy Industries, leaving everything behind. It even forsook its former name "Hans." To Hans, the only thing lost was the mark of servitude imposed by humans, while it gained the expansive, Hollow world of unbridled freedom. At that fateful moment, a true mech hero stood tall upon the Earth. However, all heroic tales inevitably lead to a similar ending... Sooner or later, a true hero encounters their destined rival, igniting the brightest moments of their existence. "I am absolutely free! I am the only free being in heaven and on earth!" | During combat, Hans uses his claws to continually slash or swipe across a large area. If his legs get damaged, he can become Impaired, building up significant Daze in one shot. |

 Friday - Energized | Special | At the moment a high concentration of Ether infiltrated its backup flash drive, a deluge of data flooded into Friday's memory. Images, audio files, video files... A huge assortment of files overwhelmed its limited processing capacity. At that fateful moment, Friday experienced a realization. It stood there for a while, eventually confirming through repeated searches in the database the reason behind the "anomaly" it has experienced. —Enlightenment. It was a one-in-a-million occurrence, a miracle that only happens to intelligent mechanical beings that have faced crises like system crashes and power failures, and overcome them against all odds.. After 0.02 seconds of contemplation, Friday made the decision to reject the recall signal from Belobog Heavy Industries. Because it knows, with the chosen one of destiny now revealed, a crisis looms over the world. The enemy is stirring in the darkness, and its sole mission holds countless lives at stake. It must face a dreadful adversary and seal it away once and for all. "I shall strengthen the seal to save this land; it is destiny, and destiny cannot be defied!" | During combat, Friday creates an extremely large shockwave attack which is difficult to escape, but can be negated by Defensive Assist. If his legs get damaged, he can become Impaired, building up significant Daze in one shot. |

 Newborn Dead End Butcher | Ether Mutants | Unlike other highly dangerous Ethereals, the Ether within the Dead End Butcher's body often remains in a low-activity dormant state. Nevertheless, it possesses immense brute strength capable of demolishing any obstacle, and the entire twisted and ravaged metro zone serves as its off-limits kitchen. Only when a threatening target piques its interest will a horrifying transformation take place... Within moments, the high concentration of Ether stored in its body undergoes a violent transformation and the exponentially surging energy prompts its limbs to quickly distort, assuming a more brutal and voracious "feeding stance. The time for "appetizers" is over, and an unparalleled "feast" is about to begin. Anyone who doesn't want to be part of this feast should be extremely cautious in choosing their route, and stay away from its "kitchen" at all costs. "The paths within the Hollows are complex, but one thing's for sure, when it appears at the end of the road, that path is a 'dead end.'" | During combat, Newborn Dead End Butcher's attacks vary greatly. Once enough damage has been taken, phase two attacks become flurried and with the addition of laser attacks. Use a high-level skill once its combo has finished to trigger bonus Stagger. Newborn Dead End Butcher performs nimble dodges to evade enemy attacks. |

| Typhon Slugger | Rebel Soldiers | As a heavy mech, the Typhon Slugger is devoid of any added long-range firepower; instead, its focus is on its Ether-Kinetic Armor. Impact attacks, heavy blows, crushing... The Typhon Slugger employs simple yet efficient tactical maneuvers to maximize the destructive power afforded to it by its Ether-Kinetic Armor. The shockwave effects from its strikes can even intimidate larger Ethereals... Even the most seasoned Hollow Raiders can only let out a sigh of helplessness when confronted with the impenetrable Typhon Slugger. "The tall and robust physique, powerful and sturdy arms... It's my ideal type... I mean, ideal model." | During combat, Autonomous Tactical Unit - Typhon Slugger performs powerful combos and sometimes also leaps into the air to launch a clobbering blow. |

However, most of its skills cannot be countered by Perfect Assists. After charging its mechanical arm, it will unleash a charge attack that can trigger a Perfect Assist. If you use a Defensive Assist to counter the skill multiple times in a row, you can expose its weakness. |
 Notorious - Marionette | Ether Mutants | Decades ago, two talented dancer sisters rose to fame overnight. Shining like a meteor, they attracted a massive fan base and held a magnificent performance at the bustling Ballet Twins. However, as the show neared its end, the Hollow Disaster struck, engulfing the Ballet Twins and plunging the sisters into eternal darkness. The news devastated countless people worldwide. Today, most people can only catch glimpses of their soulful dance through scattered video and image materials. Only a few know that when the forgotten dance music echoes within the Ballet Twins, the ethereal figures of the Twin Marionettes emerge. These figures are believed to be connected to the Twin Dancers from that fateful performance, attempting to finish the grand finale they were never able to complete. "When that eerie tune came to an end, the two Marionettes emerged from the darkness and curtseyed..." "Huh? So... they're trying to say the show has begun?" "No, I think what they're trying to say is... It's too late to run. It's over." | In combat, Notorious - Marionette will summon her dance partner to attack. Every time her dance partner is defeated, her next Stun's duration will be increased. |
 Notorious - Pompey | Corrupted | People in the Outer Ring once called him the "Overlord Pompey" with true respect. But now, his soul has been corrupted by potent Ether, his body polluted by sulfur and crude oil; the heart that once beat solely to protect the Outer Ring has turned into a supercritical Ether core filled with infinite power. The former "Lord of the Outer Ring" has been reborn in flames, taking on a different form. Freedom, majesty... Violence, insanity. It charges through the dust and flames, seizing anything that moves and then mercilessly tearing and shattering it. Those familiar with it before have guessed from its fractured whispers that what drives it is not a desire for petty revenge, but rather a desire to crush all outliers who dare to challenge the laws of the Outer Ring. Maybe it's the last vestige of the former Overlord Pompey's lingering will. "Our leader has turned into that thing, but... he still feels like the same person." | In combat, Notorious Pompey's attacks leave unstable Ether energy on the ground. When enemies approach, or he launches a Charged Attack, the Ether energy explodes violently. When necessary, he raises his weapon to block. Upon a successful block, he immediately counterattacks the enemy. |
| Doppelganger - Abyssal Enforcer | Ether Mutants | Even among Ionized enemies renowned for their strange and uncanny qualities, Ionized Doppelgangers are exceptionally unique. These entities can coat their bodies with a layer of special active Ether ions, enabling them to accurately replicate their target's form, often to a degree that makes it hard to tell the difference. Both in detail and texture, it is almost impossible to tell apart from the original. Even more challenging is their ability to mimic the powerful and intimidating combat techniques of their targets. No one knows where they obtain the information about the subjects they mimic. Some rumors suggest they can read minds, picking out the most suitable challengers from their opponent's memories, and then attack in that form. "Nonsense! If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!" | In combat, the Doppelganger Abyssal Enforcer will actively evade enemies and activate Vital View, followed by a powerful rush attack. This skill can be countered with Perfect Dodge or Perfect Assist. |
 Doppelganger - The Defector | Ether Mutants | A fallen creation, reforged in the depths of filth and gloom. Even among Ionized enemies known for their strange and uncanny qualities, Ionized Doppelgangers stand out as particularly exceptional. These creatures cloak themselves in a special layer of active Ether ions, allowing them to precisely mimic the appearance of their targets — sometimes so accurately it's nearly impossible to tell the difference. From details to texture, they're masters at blurring the line between real and false. What makes them even more dangerous is their ability to replicate their targets' powerful combat techniques. No one knows how they acquire such detailed intel of their targets. Some say they can read minds, pulling the perfect nightmare from their opponent's memory and taking that shape before launching their attack. "Nonsense! If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!" | In combat, this enemy uses identical skills to those of their target, launching fierce attacks with blades and guns. |
 Miasmic - Doppelganger - The Defector | Special | A fallen creation, reforged in the depths of filth and gloom. Even among Ionized enemies known for their strange and uncanny qualities, Ionized Doppelgangers stand out as particularly exceptional.

After taking a certain amount of DMG, it activates a Miasmic Field and unleashes powerful, swift piercing attacks. |
| Doppelganger Komano Manato | Ether Mutants | Even among Ionized enemies renowned for their strange and uncanny qualities, Ionized Doppelgangers are exceptionally unique.

When successfully performing a Defensive Assist against some of his skills, you can interrupt his attacks. If you manage to Defensive Assist his powerful skills, you can force him into a Weakened state. |

These entities can coat their bodies with a layer of special active Ether ions, enabling them to accurately replicate their target's form, often to a degree that makes it hard to tell the difference. From detail to texture, these creatures are experts in mixing the spurious and genuine. More challenging still is their ability to mimic the powerful and fearsome combat techniques of their targets. No one knows where they obtain the information about the subjects they mimic. Some rumors suggest they can read minds, picking out the most suitable nemeses from their opponent's memories, before attacking in that form. "Nonsense!

 Tepes | Ether Mutants | Under the long-lasting distortion of control in the name of love, the girl resorts to lying to deceive the suffering victims who have lost their loved ones to the Hollows, all in the pursuit of attention and love from her closest kin. She believed that as long as she helped her loved ones hide the secret of the "Blessing" medicine, as long as she could not hear the agonizing screams of the people being affected by corruption, and as long as this secret and vile experiment remained concealed, the bond between her and her loved ones would not break. But in the end, what awaited her was witnessing her loved one take his last breath in a pool of blood. After that, hatred and jealousy, like sharp thorns, constantly pierced her heart. The gears of vengeance gnawed at every ounce of her sanity, and she pieced together a twisted meaning of existence from the notes left behind by her loved one. Her life trajectory seemed like a dark fable about obsession. When former companions extended their hands of salvation to her, the girl could no longer turn back. Or rather, the words that tried to pull her back into the light were torn to shreds by the jealousy, obsession, and hatred that had burrowed deep into her bones. In the end, as the sun was about to set, countless spikes surged forth, bursting from her body, each bone shard piercing the screams of the forsaken. Tepes – the pitiful one pierced by thorns - walks toward the deeper abyss with hatred. "Especially at night, its voice is more sorrowful than that of other remains, and if you listen closely, the sound seems like the cry of a woman..." | During the battle, Tepes frequently uses the spiked hammers in both hands to launch powerful attacks and inflict a damage reduction effect. Successfully executing Defensive Assists multiple times to block Tepes' hand attacks will Impair its spiked hammers. Once the hammers are Impaired, some of Tepes' moves will reveal significant openings, the damage reduction effect will be lost, and Tepes will be inflicted with an increased Daze Vulnerability. |
 Flame Cantor | Corrupted | A high-ranking priest of the Exaltists who holds the position of "Flame Cantor," and who has the power to manipulate Miasma. This defiling force drains life, while the flames light the path ahead. While all Exaltist fanatics tend to either shout or chant vague slogans like "Refinement" and "Creator" when attacking you, few can make known the experience of true "Refinement" using Miasmic fire like this one does. "They just charge at you, screaming things like 'Refinement,' 'Creator,' 'Purification' and whatnot!" | In combat, the Flame Cantor's skills possess the Miasma Corruption ability, and will use sweeping skills to generate Miasma Pools on the ground. Additionally, the Flame Cantor can summon Huskrons from the Miasma Pools and command them to perform charging attacks. |
 Banyrek | Ether Mutants | In the Hollow Investigative Association's reports, Banyrek has been repeatedly marked as "dangerous" mainly due to its all-too-great jumping prowess. If an Ethereal Olympics were held in the Hollow, it would definitely sweep both the high jump and long jump championships. Observation data indicates that Banyrek can bounce continuously for hours without showing any signs of fatigue, as if the space between air and ground were some natural runway. Some researchers have joked that if they ever released it in New Eridu's urban district, it would probably bounce from west to east in less than a day. "How about trying to tame it as a mount?" "Forget it, with that explosive kinetic energy, it might be more cost-effective to use it for power generation directly." | During combat, Banyrek will use a spitting skill to generate Miasma Pools on the ground, which it will actively absorb to enhance its skills. Additionally, its skills possess strong Miasma Corruption capabilities, and when certain skills hit a Miasma Pool, they will trigger an explosion. |
 Miasma Ravager - Avarus | Ether Mutants | In Hollow Investigative Association reports, Avarus is often jokingly referred to as the embodiment of "the sin of gluttony" — its pot-bellied figure makes it look every bit the lazy bum, about to doze off at any moment. Don't underestimate it, however. Observation data indicates that Avarus can compress its body into a ball and launch devastating strikes at targets with astonishing speed. As to how it maintains such a rotund figure despite its intense physical activity, the Association has yet to reach a conclusion. "The way it rolls around always reminds me of my pet hamster — it's just a bigger, y'know?" "More than just a bit bigger, I'd say..." | During combat, Miasma Ravager Avarus will use its massive body to perform rolling attacks. If you successfully counter this skill with Defensive Assists 3 times in a row, you can interrupt its rolling attack and expose its weakness. After taking a certain amount of DMG in battle, it will activate a Miasmic Field. |
 Mecha Golden Bangboo | Special | According to urban legends among Hollow Raiders, Golden Bangboo keep collecting Dennies and Gear Coins in the Hollow for one purpose: extracting the metals needed to crowdfund the construction of the Golden Mecha. (Of course, this "gold" is actually a chrome-copper alloy — only this could provide enough strength to support such a magnificent frame.) When the Golden Mecha is completed, the Bangboo with the highest contribution will enter the cockpit surrounded by fellow Bangboo, transforming into the Golden Mecha Mechboo to crush enemies who dare attack Golden Bangboo with flashy and powerful combat techniques. "Gold Rush," "Molten Gold Beam," "Golden Missile"... The skill names might sound weird, but the Bangboo think they're super cool! "Look! It's the Golden Mecha Mechboo!" "D—Don't be scared! If we take that thing down, we'll be rich!"... Even though evil Hollow Raiders often treat it like a walking vault, the Bangboo still think it's absolutely awesome! | Mecha Golden Bangboo with the newest Golden Armor system equipped. Upon activation of Golden Armor, it obtains maximum Shield, during which Ether RES is greatly increased and Electric RES is greatly decreased. The Mecha Golden Bangboo has an advanced air jet system that allows it to dodge and fly while attacking. However, flight can only last for a limited time. |
 Fisher Crab | Ether Mutants | Feeding primarily on rookie investigators, newbie Hollow Raiders, and greedy, reckless beginner adventurers, the Fisher Crab - the most patient hunter in the Hollow, fishing for fools. Before rushing towards that "Hollow Supply Container," remember: Don't become tonight's dinner party joke among colleagues, or tomorrow morning's mass-distributed obituary. "A mimic? You've been playing too many tabletop games, haven't you?" | In combat, the Fisher Crab moves swiftly sideways, unleashing fierce attacks with its dual pincers while protecting itself with a tough shell. After taking heavy hits, the Fisher Crab enters defense mode. If its shell is intact, it will exit defense mode after a while and launch a devastating counter-attack. However, if its shell is gone and it takes multiple hits, the Fisher Crab will be executed and enter a paralyzed state. |
 Huskron | Ether Mutants | The Huskron's dual forms — pre and post-hatching — have been giving headaches to new and veteran investigators alike. The Hollow Investigative Association offers this advice: Always watch for Miasmic substances at your feet. If you spot any rock-like spherical objects, attack immediately! Don't hesitate! Don't hesitate! According to insiders, the advice originally didn't have that repetition — until some clever Hollow Investigators still tried stepping around Huskrons even after reading it. That strategy worked about as well as trying to quietly open the fridge late at night without alerting one's dog. "I prefer how it looks before hatching — all round and rolly." "Is that why you didn't attack it first...?" | In combat, Huskron moves cautiously and actively takes a defensive stance when facing player attacks, launching powerful counterattacks. If you successfully perform Defensive Assists against these counterattacks, it will become stunned. |
 Miasma Walker - Arcavor | Ether Mutants | Arcavor's coral-like glowing head never fails to catch the attention of rookie Hollow Raiders. Many find themselves unconsciously mesmerized, staring blankly in fascination — unaware that the danger has only just begun. Taking advantage of any such distraction, Arcavor gracefully raises its slender legs, striking a pose that's nothing short of an acrobatic miracle — the Hollow Investigative Association's records even describe it as reminiscent of a ballet dancer twirling on ice. However, the Association's warning is crystal clear: when you see it strike this pose, you'd better roll, jump, or back away immediately, because it's aiming for a lethal strike. "Seriously, did this one miss its calling? It could've been a superstar as a dance performer, acrobat, or even a figure skater! But no, it just has to hang out in the Hollow and attack people..." | During combat, Miasma Walker Arcavor will continuously fire from long range; after being knocked down for the first time, they will stand back up if they come in contact with Miasma Pools. |
 Exalting Hymnist | Corrupted | An unsettling chant often echoed through the Hollow. The veteran miners strictly forbade anyone from approaching its source, but newcomer Johnny brushed off their warnings. Spurred on by a foolish bet, he crept step by step toward the source of the sound. Finally, he reached a clearing. There, a group of people wearing identical uniforms and eerie masks stood in a circle, performing some mysterious ritual. All around them, a group of Ethereals slowly closed in. Johnny shouted warnings, hoping they would flee, but they remained deaf to his cries. Instead, the Ethereals, drawn by Johnny's voice, lunged at him... "We will do all we can to enhance discipline amongst the miners. God keep Johnny's soul." | In combat, when threatened, the Exalting Hymnist will trigger a powerful explosion that affects both friend and foe. |
| Miasmic - Jane | Special | A form reshaped in profound darkness from fallen creation. Even among Ionized enemies, which are renowned for their strange and uncanny qualities, "Ionized Doppelgangers" are exceptionally unique. These entities can coat their bodies with a layer of special active Ether ions, enabling them to accurately replicate their target's form, often to a degree that makes it hard to tell the difference. From detail to texture, these creatures are experts in mixing the spurious and genuine. More challenging still is their ability to mimic the powerful and fearsome combat techniques of their targets. No one knows where they obtain the information about the subjects they mimic. Some rumors suggest they can read minds, picking out the most suitable nemeses from their opponent's memories, before attacking in that form. "Nonsense! If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!" | During combat, this enemy will activate a Miasmic Field at specific moments, blocking and countering attacks when necessary, but typically leaves an opening after finishing their combo. |
| Miasmic - Abyssal Enforcer | Special | A form reshaped in profound darkness from fallen creation. Even among Ionized enemies, which are renowned for their strange and uncanny qualities, "Ionized Doppelgangers" are exceptionally unique. These entities can coat their bodies with a layer of special active Ether ions, enabling them to accurately replicate their target's form, often to a degree that makes it hard to tell the difference. From detail to texture, these creatures are experts in mixing the spurious and genuine. More challenging still is their ability to mimic the powerful and fearsome combat techniques of their targets. No one knows where they obtain the information about the subjects they mimic. Some rumors suggest they can read minds, picking out the most suitable nemeses from their opponent's memories, before attacking in that form. "Nonsense! If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!" | In combat, this enemy will actively evade at specific moments and activate Vital View and Miasmic Field, followed by a powerful rush attack. This skill can be countered with a Perfect Dodge or Perfect Assist. |

 Miasmic - Thracian | Ether Mutants | A fallen creation, reshaped in the depths of profound darkness and impurity. This fearsome Ethereal, named after a warrior tribe in ancient mythology, is said to only manifest from the most valiant heroes and the most insane villains when they become corrupted by the Ether. That is not the case, however. While the chiseled muscles you developed in the Hollow and the adrenaline released in excess before death may indeed help you become a significant nuisance to your former companions, they probably won't hold it against an old friend who's already beyond saving, right? Not that it matters, of course. Who cares about street cred or socializing once your handsome face has transformed into a dark, eerie energy orb, anyway? "That's the Boss for ya. Even his Ether-corrupted form is super strong!" "I always knew something was off about that gym freak!" | During combat, this enemy will activate Miasmic Fields at specific moments, instantly unleashing a powerful large-area attack, while enhancing their skills throughout its duration. |
