C-Virus

C-Zombies

C-Zombie; AKA: Whoppers, Shriekers, Bloodshot

^{Click to see Whoppers}

^Shriekers

^Bloodshots]

Other Appearances: Umbrella Corps, Marhawa Desire

A C-Zombie (often referred to as "zombie") is a human mutated from inhaling the C-Virus. Chronologically, they were first independently identified during the 2011 Marhawa Desire incident and emerged en masse in 2013.

---

• Body Horror:
  • With the massive tumor having grown out of their chest, the Shriekers are the most visually distinct of the standard C-Zombie.
  • The V-ACT process melts all the skin of the Bloodshot, making them a mass of steaming red muscle tissue and pus that resemble Lickers. Their face is significantly more deformed than normal zombies, and their teeth are jagged and twisted, sticking out directly from their mouths. All in all, they barely resemble a human anymore.
• Dead Weight: The Whopper, hands down, is one of the biggest and fattest zombies ever to grace gaming history. It’s morbid obesity even works against it, as its stated in the game that the creature’s weight puts extra stress on its legs, making the Whopper extremely vulnerable to Knee Capping.
• Enemy Summoner: The Shrieker not only can use its screams to disorient its targets, but it can also galvanise and draw any nearby zombies in the area to them as backup.
• Fragile Speedster: They're very nimble compared to their t-Virus cousins, but just as frail.
• Giant Mook: The Whoppers are not just overweight, they tower over other zombies and normal humans.
• Kevlard: The Whoppers are overweight zombies with enhanced durability from their girth. This is what mainly distinguishes them from the rank-and-file C-Zombies as they have no real tricks otherwise.
• It Can Think: An fairly downplayed example compared to the Plagas hosts, but C-Zombies are not entirely mindless. They're capable of forming primitive tactics in unison, bob and weave to avoid gunfire, are capable of operating fairly complex traps and even using weapons, ranging from knives, bottles and axes, to dynamite and firearms. However, due to their problematic motor functions their melee attacks are sluggish, wild swings and their aiming skills are poor, rendering them incapable of doing more than wildly spraying gunfire in the vague direction of a target and tossing the gun at them when the weapon finally runs dry.
• Make Me Wanna Shout: The Shriekers gimmick is to scream an ear-piercing yell that will stun the player, allowing them to close the gap for a chomp or attract other zombies.
• Our Zombies Are Different: C-Zombies fit the popular modern example of a rage zombie than a traditional shambler or the more distinct Plagas hosts. However, they are driven by an instinct to feed much like the everyday zombie. However, they can’t infect other people by any means other than exposure to the C-Virus gas itself, so the outbreak will eventually burn itself out when the gas inevitably disperses.
• Plague Zombie: Subverted. It actually becomes a plot point in some instances that C-Zombies don't infect others through fluids (i.e biting). This fact, coupled with their speed, essentially makes them more akin to feral humans than zombies.
• Turns Red: A zombie undergoing the V-ACT process is distinguished by their red eyes and articles of clothing. After they turn into one, they literally turn fully red per namesake.
• Spikes of Villainy: There are also a series of very small spikes that protrude along the Bloodshot's spine.
• Superior Successor: With the t-Virus zombies suffering Villain Decay in a world increasingly familiarized with their slowness and many vaccine variants on hand, C-Zombies renewed the threat of their kind through their heightened ferocity, intelligence and wider variety.
• Zombie Puke Attack: Like their cousins, they are capable of puking acid in some instances.
• Zombie Gait: downplayed, but still there. C-Virus Zombies, albeit significantly faster than their T-Virus cousins due to moving at a quick walking pace by default compared to the former’s constant slow shamble, are still fairly slow and easy to outrun. And despite being capable of sprinting and leaping after targets just as well as a living human, these bursts of speed are usually short lived.

J'avo & Complete Mutations

A pack of Neo-Umbrella J'avo

^{Complete Mutation 1: Strelac}

^{#2: Napad}

^{#3: Mesec}

^{#4: Gnezdo}

^{#5: Lepotica}

^{#6: Ubistvo}

Other Appearances: Marhawa Desire (as mutated forms of Bindi Bergara and Nanan Yoshihara)

Humans injected with the C-Virus. J'avo do not lose their intelligence and gain increased durability and ferocity, but it is their ability to regenerate wounds by triggering selective cellular mutation, allowing them to transform into a variety of different forms, that truly makes them dangerous. In rare cases, they may enter cocoons and in undergo a complete genetic transformation, becoming a monster called a Complete Mutant.

The Edonian Liberation Army used J'avo during the Edonian civil war, and Neo-Umbrella effectively has a private army of J'avo supersoldiers at their disposal.

---

• Action Bomb: Telo-Ekspolzija, as their name indicates, are living suicide weapons that blow up when shot or if they get close enough to a victim.
• Ax-Crazy:
  • Typical J'avo suffer from a bad case of this, having been driven psychotic from the infection and consequently lashing out at anything that crosses their path. However, the Neo-Umbrella operatives are much more restrained.
  • The Ubistvo is utterly, chair-leg savaging bonkers. The file for it notes it can't even be properly directed, just pointed in the general direction of a target and let loose.
• Adaptive Ability: Their special trademark. Hit them in a specific area, and they may mutate it to give them a new power. Or they may transform into a Complete Mutation.
• Armless Biped: Strelats have no arms, despite running around on two legs.
• The Berserker:
  • Glava-Begunats J'avo and Napads both attack wildly and ferociously, with no greater purpose than rending victims apart with their bare hands.
  • The Ubistvo is just a mindless killing machine that attacks everything in sight with its chainsaw arm.
• Beware My Stinger Tail: Strelats can lash a foe with their barbed tail up close.
• Blade Below the Shoulder: The Ruka-Srp mutation is a "blade replacing the limb" variant, giving the J'avo a massive, sickle-like reaping claw.
• Body Horror:
  • Just the default J'avo has a torn-up face with multiple, slime-weeping inhuman eyes staring out at random points. But it is their mutative abilities that truly distort them into grotesque new forms.
  • Lepotica is a pear-shaped, vaguely feminine creature whose head can open up like a flower, with its upper jaw hinging open 180 degrees before the right and left sides of the face peel away, to expose a lashing, worm-like tongue. It's also covered in dozens of viral gas-generating sacks on its torso that look like sagging breasts.
  • Ubistvo has bony armor growing out of its twisted legs, a severe case of Two-Faced that's resulted in half of its face being just… gone so that two bugs can protrude from where the brain was, and its right arm is twisted into an organic chainsaw. Which is actually made up of its heart and ribcage.
• Bee Afraid: The Gnezdo is probably one of the strangest mutations ever, going from a human to a large bee that controls swarms of fly-like insects.
• Breath Weapon: The Glava-Dim J'avo constantly exhale a toxic smoke that poisons and blinds anyone who comes near them.
• Chainsaw Good: The Ubistvo has either grown an organic chainsaw-like appendage or, more likely, a chainsaw was fused into its biology during its mutation process.
• Combat Tentacles: The Ruka-Khvatanje J'avo use their centipede-like arm to reach out and grapple victims from afar in a case of Tentacle Rope. If they want to soften their victim up first, they can just pummel them senseless from afar by using their arm like a giant whip.
• Creepy Crows: The Mesec look like distorted, humanoid crows.
• Degraded Boss: The first Napads and Gnezd encountered in Chris' campaign are considered mini-bosses but following this and in Jake and Ada chapters, they aren't that difficult to defeat.
• Elite Mooks: Neo-Umbrella J'avo are essentially supersoldiers: they have military training, naturally employ better tactics, are better armed, and will almost always undergo any kind of mutation.
• Extremity Extremist: J'avo will only make melee attacks with the limbs that have mutated. Noga-Oklop J'avo in particular relies on kicking first and foremost, even ignoring their guns to do so.
• Eyes Do Not Belong There: A J'avo's face sprouts multiple eyes as part of the infection, visibly tearing up their face in the process.
• Faceless Goons: The J'avo in China wear Peking opera masks, obscuring their deformed faces.
• Fog of Doom: The Lepotica creates this by dispersing clouds of C-Viral fumes, turning those near her into C-Virus Zombies.
• Gas Mask Mooks: The Neo-Umbrella J'avo wear gas masks evocative of Umbrella U.S.S. operatives.
• In a Single Bound: Noga-Skakanje J'avo are just as capable of leaping around as the grasshoppers they resemble. Noga-Trchanje aren't so spectacular at leaping, but still make some mighty impressive jumps and pounces.
• It Can Think: J'avo retain all of their previous human intelligence, allowing them to plan, communicate, coordinate attacks, and effectively use their guns. They're also largely in control of their mutations ala heightened mutants that usually serve as bosses in the franchise.
• Luckily, My Shield Will Protect Me: Ruka-Bedem J'avo are Nigh-Invulnerable if you try to attack their mutated arm-shield.
• Meaningful Name: All of the specific mutation strains, the Complete Mutations, and even the name J'avo itself all have some logical reference behind them in Serbian, the language of the region where they are first encountered.
  • J'avo is a dialect variant of "davo", the Serbian word for "Devil".
  • All of the J'avo mutations begin with either "Glava", "Ruka", "Noga", or "Telo", the Serbian words for "Head", "Arm", "Leg", or "Body" respectively. Take a wild guess where each mutation manifests itself?
    • "Glava-Sluz", meaning "Head-Slime", is a mutation that grants Super Spit.
    • "Glava-Smech", meaning "Head-Laughter", is a mutation that replaces the head with an impossibly wide, gaping mouth.
    • "Glava-Begunats", meaning "Head-Runner" or "Runaway Head", is a mutation that turns the J'avo into The Berserker.
    • "Glava-Dim", meaning "Head-Smoker", is a mutation that grants the J'avo a toxic smoke-based Breath Weapon.
    • "Ruka-Srp", meaning "Arm-Sickle", creates a mantis-like talon that functions as a Blade Below the Shoulder.
    • "Ruka-Khvatanje", meaning "Arm-Capture" or "Catcher Arm", creates a centipede-like limb that can reach out and snag someone like Combat Tentacles of the Tentacle Rope variety.
    • "Ruka-Bedem", meaning "Arm-Wall", creates a super-durable shield to cover the torso and head.
    • "Noga-Trchanje" meaning "Leg-Work", turns the J'avo into a spider-taur creature that has Wall Crawling and enhanced leaping abilities.
    • "Noga-Let" meaning "Leg-Flight", gives the J'avo wings and lets it fly.
    • "Noga-Skakanje" meaning "Leg-Hopper" or "Leg-Jumps", gives the J'avo grasshopper-like legs that allow them to jump huge distances, which they favor doing in order to ambush prey in melee or get to a better firing angle.
    • "Noga-Oklop" meaning "Leg-Armor", covers the J'avo's legs in powerful armored muscles that deflect bullets and let it deliver devastating kicks.
    • "Telo-Ekspolzija", meaning "Body-Explosions", turns the J'avo into an Action Bomb.
    • "Telo-Krljusht", meaning "Body-Scales", covers the J'avo in a biological Bulletproof Vest that makes them Nigh-Invulnerable.
    • "Telo-Magla", meaning "Body-Mist", causes the J'avo to start generating obscuring mist.
  • The "Strelats" mutation takes its name from the Serbian for "to shoot" or "shooter", and it attacks primarily with a biological Flechette Storm.
  • The "Napad" mutation takes its name from the Serbian for "attack" or "assault", and it's the most heavily armored and violent mutation.
  • The "Mesec" mutation is a flying Creepy Crows creature that takes its name from the Serbian for "moon".
  • The "Gnezdo" mutation takes its name from the Serbian for "nest" and is a hive-minded swarm of mutant insects.
  • "Lepotica" means "(Feminine) Beauty" in Serbian, serving as an Ironic Name referring to its grotesquely feminine form.
  • In Serbian, Ubistvo means "Murder", and it's The Berserker and armed with an array of One-Hit Kill attacks.
• Nigh-Invulnerable: You cannot hurt a Napad unless you breach its armor, whilst Telo-Krljusht J'avo can't be hurt, period, by anything directed to the chest region. Headshots, limb shots, and explosives are another story though. Meanwhile, Gnezdo are immune to pretty much any attack that doesn't hit their Hive Queen.
• Pupating Peril: J’avo that are wounded enough will become encased in a cocoon, and will emerge as a significantly more dangerous Complete Mutation unless said cocoon is smashed before the transformation is complete. However, this does not extend to just J’avo, with some progressing straight to the cocoon stage after becoming infected.
• Painful Transformation: The mutations that the J'avo undergo when wounded are not pleasant if the fact that they hunch over in pain or cry out as their limb tears (complete with blood and gore) itself apart and puts itself back together into a grotesque new form within a matter of seconds is anything to go by.
  • The transformation into a J'avo itself must not be very pleasant either considering that Jake's squad screamed in pain as they were changing.
• Super-Soldier: J'avo are this to a T, having been made either from Hired Guns or have been given military training and are capable of standing on fairly even ground with the BSAA.
• Super-Strength: Napads and Noga-Oklop J'avo are immensely strong and hit like a runaway train if you let them get close to you. Regular J'avo also have this to an extent, as one has been seen giving a soldier a Neck Lift without much effort.
• Super Spit: The Glava-Sluz J'avo can spray a noxious slime that encases a victim and holds them in place.
• Slasher Smile: The J'avo encountered in the game have a disturbing habit of doing this. But one of the real scenes where it shows is the first time the Ruka-Srp mutation is introduced, where after said J'avo's arm is shot, it proceeds to mutate into a Sinister Scythe while the J'avo grins full force in an utterly murderous manner and stares Chris down.
• Sinister Scythe: The Ruka-Srp mutation turns the J'avo's arm into a Blade Below the Shoulder, with the elbow inverted and everything else all the way down reconfigured into a jagged, mean-looking sickle.
• Tears of Blood: In an overlap with Bad Black Barf; J'avo weep thick, slimy black tears from all of their eyes, covering their faces in trails of noxious black muck.
• Winged Humanoid:
  • Noga-Let J'avo are a twisted variant; their legs have mutated by fusing together into a single large moth-like organism, which flies whilst trailing the still-conscious and aware humanoid torso of the J'avo beneath it like a disfigured, oversized abdomen.
  • Telo-Magla J'avo are a technicality; they have multiple wings growing from their bodies, but these can't fly, they just disperse the smoke it secretes around their body.
  • Mesec are humanoid Creepy Crows with fully functional wings.
• The Worm That Walks: The Gnezdo are a variant of these; most of their bugs are small, making them extremely hard to hurt, but their consciousness resides in a single massive bee-like "Hive Queen" — kill it, and you kill them.

Brzak

A B.O.W. created by The Family to elaborately dispose of incriminating evidence.

---

• Body Horror: Brzak resembles a monstrous, deformed shark with claw-like hand-flippers and an extendable claw on its tongue.
• Threatening Shark: Brzak, in a nutshell. A giant intelligent shark that likes freshwater, has something approaching Combat Tentacles for a tongue, and can climb on land.
• Meaningful Name: Brzak means "rapids" in Serbian, and it's a fish-like monster fought in the middle of rapids.
• Sadist: Files note the Brzak is not interested in eating anything that isn't alive, even corpses, thus implying it enjoys toying with live prey. The Family employees always had to push around disposables to trick it into believing they are alive.
• Was Once a Man: Despite having the appearance of a shark, the Brzak is actually of human origin, most likely after undergoing a Complete Mutation.

Ogroman

A successful C-Virus-derived B.O.W. that sees widespread use in regional conflicts.

---

• Attack Its Weak Point: Shy of breaking out the heavy artillery, the only way to properly hurt an Ogroman is to pull its heart out through its back and shoot it repeatedly.
• Body Horror: Ogroman is a distorted, hunch-backed, skeletal giant with a too-wide mouth that contains only a handful of twisted, tusk-like teeth. It also has a mechanical implant dangling out of its hump; pulling on this will yank its distorted heart mostly out of its body, exposing its weak spot.
• Dumb Muscle: According to its file, the Ogroman is dumb as a sack of bricks. Even so, it's monstrously strong to the point of needing airstrikes or missiles to take it down.
• Meaningful Name: Ogroman means "Enormous/Gigantic" in Serbian, and is a towering giant creature.
• Our Giants Are Bigger: Ogroman is the biggest humanoid B.O.W seen in the series, surpassed only by the Uroboros Aheri from Resident Evil 5.

Iluzija

A Neo-Umbrella B.O.W. unleashed on the BSAA during their operations in Lanshiang.

---

• Animalistic Abomination: Even though it was human once, the effects of the C-Virus have twisted them into an eyeless, hulking snakelike beast as long as a bus and as big as a car, covered in irregular bone growths and possessing human-level intelligence, the ability to camouflage itself and a mouth filled with semi-autonomous, insectoid teeth.
• Body Horror: Iluzija resembles a giant, eyeless snake with skin torn open over underlying bone plates in random spots and a mouth filled with what are either wriggling fangs or insect claws.
• Eyeless Face: The Iluzija's eyes are just… gone.
• Invisibility: The Iluzija's main gimmick is that it can turn invisible, letting it ambush the player and their partner. Its file reveals this is achieved by secreting a liquid over its body that bends light, allowing it to camouflage itself against the naked eye.
• It Can Think: Like many other victims of the C-Virus, these infected are unique in that they retain a lot of their former intelligence. The Iluzija, however, stands out the most considering that it both sadistically taunts its hunters, as well as use its cloaking ability to stalk them and observe as well as draw the team away from each other for an easier kill.
• Meaningful Name: Iluzija means "illusion" or "phantom" in Serbian, and it's capable of rendering itself invisible.
• Scaled Up: Iluzija is a gargantuan, man-eating, invisible snake with human-like intelligence… because it used to be a human.
• Sense-Impaired Monster: Despite having no eyes, it's able to take on BSAA troops with ease. It's not clear how it compensates, though some ability to sense body heat is quite plausible.
• Was Once a Man: Despite its appearance, unlockable files reveal that the Iluzija was of human origin, most likely after undergoing a Complete Mutation.

Rasklapanje

An irregular parasitic C-Virus mutant.

---

• Animate Body Parts: Rasklapanje takes this to the level of being a twisted variant of The Worm That Walks.
• Body Horror: Rasklapanje looks like it has melted its skin, almost leech-like, before its various body-parts separate and crawl around with throbbing, pink, intestinal-looking tentacles.
• Chest Burster: Their method of reproduction involves seemingly implanting a parasite or embryo in a victim's body, which rapidly grows and then bursts out through their chest.
• Expy: The Rasklapanje's physical appearance, independently mobile body parts, penchant for traveling through sewer pipes, and disturbing method of reproduction are all eerily reminiscent of Flukeman, one of the more infamous Monsters of the Week from The X-Files.
• Face Full of Alien Wing-Wong: Implied. Their unique kill scene involves devouring their victim's head, which is followed by a new Rasklapanje bursting out through their dead body's chest.
• Healing Factor: You basically can't kill a Rasklapanje, it just regenerates all the damage you do. The only ones who actually die in a cutscene show that extreme methods (being shoved in a meat grinder and falling in a vat of molten metal) are needed.
• Meaningful Name: Rasklapanje means "Dismantle" in Serbian, and it has the power to break down into a swarm of Animate Body Parts and then reassemble itself.
• Not Quite Dead: Due to Rasklapanje's Healing Factor, when they "die", you can clearly see that they're still twitching and making creepy sounds.
• The Worm That Walks: Rasklapanje's various organs are all independently thinking and functioning creatures that just so happen to choose to form a single humanoid form at times. For bonus points, even in their combined state, they look like a humanoid leech.

Ustanak

A human-based B.O.W. successfully derived from a loyal subordinate of Carla Radames. It now serves as her loyal right-hand enforcer.

---

• An Arm and a Leg: A file mentions the man that became Ustanak lost his right arm in a lab accident. This led to its replacement with detachable and weaponized prosthetics.
• Avenging the Villain: It's implied by the file "Ustanak 2" that part of the reason he's Dragon His Feet after Carla's death (other than his standing orders) is because he's angry and wants revenge on her killers.
• Bad Boss: Despite his loyalty to Carla, Ustanak will kill J'avo mooks for either failing or inconveniencing him.
• The Brute: A towering musclebound hulk that does Carla's dirty work, Ustanak provides the main physical threat in Jake's campaign.
• Crazy-Prepared: He carries around spare arms for different purposes so that he can stay up to speed in any fight. Helena even acknowledges this in her one encounter with him.
  Helena: Give him credit. At least he came prepared.
• Determinator: Just like his predecessor, he doesn't know when or how to quit. Once you have been targeted, you are as good as dead, unless you are a badass like our heroes/heroines.
• The Dragon: To Carla, serving as her attack dog. It's all but stated Ustanak's occupied this role even before his transformation.
• Dragon Their Feet: Ustanak manages to outlive Carla and continues pursuing its original mission.
• Dumb Muscle: Subverted; despite its inhumanity, he keeps an impressive level of intelligence. He's capable of using and adapting its equipment to the task at hand and will wise up to Jake and Sherry's stealth tactics if they futz up too much. In fact, one file mentions the C-Virus may have actually increased his intelligence as a side effect.
• Facial Horror: Looking up close shows that one of his eyes is swollen almost shut, his nose is crooked and off-centre, his lips and part of his mouth have been pulled up to expose the gums and broken teeth, and he appears to have a small crater in the side of his skull.
• Faster Than They Look: Lampshaded by Sherry:
  Sherry: He sure can move fast for something that size.
• Final Boss: Of Jake's campaign.
• Genius Bruiser: Downplayed. It may not look that way and it isn't exactly a genius, but it can wise up to Jake and Sherry's tactics, carry extra weaponized prosthetics to change its own tactics if it finds itself at a disadvantage, and can use the environment around it to its advantage as well.
• Handicapped Badass: Ustanak may be half blind and down one natural arm, but he's still hard as nails and capable of ripping Jake or Sherry apart in combat.
• The Heavy: In Jake's campaign, he is the main threat in lieu of the main villains, Carla and Simmons, being occupied elsewhere.
• I Just Want to Be Badass: If one of the files really is his diary entry just before being injected, all he once dreamed of was being reborn as a super-powered being. Safe to say that he got that wish granted.
• Implacable Man: He relentlessly hunts down Jake and Sherry, whether they're running from him inside a building, or trying to escape it while on a helicopter.
• Lightning Bruiser: Don't let his size fool you; this thing is incredibly fast and deadly in melee range. Sherry even acknowledges that it is fast for its size.
• Meaningful Name: "Revolution" in Serbian, signifying its brute strength.
• Mook Maker: Creates the Oko creatures from an organ on its back. They function as a Patrolling Mook for it.
• Patrolling Mook: It generates Oko, grotesque bat-insect creatures that act as moving eyes for Ustanak. If one sees you out in the open, it will quickly shriek and alert him to your location. Thankfully, he only uses them while hunting the protagonists through a cavern.
• Recurring Boss: Hounds Jake and Sherry from beginning to end and even has a round with Leon and Helena.
• Sense-Impaired Monster: Ustanak seems to be at least somewhat blind (based on the fold of flesh over one eye,) but his hearing is definitely sharp. Firing a gun in the cavern level will rapidly cause him to home in on your position.
• Shotguns Are Just Better: One of its arm cannons is essentially an oversized shotgun.
• Strong as They Need to Be: The Ustanak's strength fluctuates depending on how much of a threat the plot needs him to be. He can go from a Nigh-Invulnerable One-Hit Kill machine to being weak enough that Jake can trade blows with him in close quarters.
• Super-Toughness: Over the course of the game, Ustanak survives several boss fights, falling from a great height, getting impaled through the stomach with a mining drill, and being burnt alive in a pool of lava. He finally dies after being shot in his exposed heart with a magnum.
• Swiss-Army Appendage: It has a lot of accessories for its artificial arm, including an Arm Cannon, an Epic Flail, a syringe, a drill, and Wolverine Claws.
• Tranquil Fury: After Carla's death, a file mentions that Ustanak seems to be aware of her demise and is deeply enraged over it despite his outwardly quiet manner.
• Undying Loyalty: A file mentions it has this towards Carla. According to another file, he had been this way before being transformed into Ustanak.

HAOS

The brainchild of Carla Radames as leader of Neo-Umbrella. HAOS is a B.O.W. created only to end the world: when released upon the world, it will unleash the airborne variant of the C-Virus on a planetary scale. There is a contingency plan to release it in the event of Carla's death.

---

• Attack of the 50-Foot Whatever: Before it starts shrinking down to keep pace with Chris and Piers, this thing is huge. Even its torso is massive enough to tower over the duo by leaps and bounds.
• Advancing Boss of Doom: The first couple of stages just consist of running from HAOS as it rampages about behind you.
• Artistic License – Biology: An odd subversion. While there are many examples of the C-Virus stretching the bounds on conservation of mass with its mutations (with the enhanced C-Virus breaking the bubble entirely), there seems to be a hint that HAOS was made using numerous bodies. Examining its chrysalis with a sniper rifle, one can see encased bodies sticking out of the cocoon.
• Beast of the Apocalypse: This is HAOS's intended role - should it reach the surface, it would begin spreading the C-Virus in a similar way to the Lepotica while rapidly spawning smaller clones of itself. These HAOS creatures and the C-virus would spread across the world in a matter of days to weeks, collapsing society and causing The End of the World as We Know It.
• The End of the World as We Know It: Designed to do this, though it was awakened too early to be fully active, and is killed before it can carry out its mission.
• Final Boss: Of Chris's campaign.
• Gameplay and Story Segregation: Possesses no attacks that spread infection, despite it being its main function. In fact, how Chris and Piers even survive in its vicinity is left completely unexplained. However, judging by the fact that HAOS was prematurely born in the wake of Carla’s death, it’s entirely possible that capability may have become flawed or rendered outright defunct by said rushed birth.
• Genetic Abomination: While it would have most likely counted even if it was completed, HAOS is a hideous, gargantuan beast that consists of a shapeless tentacled mass propping up a humanoid torso with translucent skin, boneless limbs and a skull for a face capable of shifting sizes at will, created by Carla as her very own Beast of the Apocalypse.
• Healing Factor: Regenerates from being blown in half a few times over the course of the final battle.
• Implacable Man: Takes multiple rounds of fire and battles to take down. And even then, it only dies from Piers' final attack and the base explosion.
• Make My Monster Grow: Inverted, when HAOS first emerges from the cocoon, it's humongous. As he's damaged in battle and forced to chase Chris and Piers in smaller rooms and corridors, he emerges from its desiccated remains in a smaller form to keep on fighting.
• Meaningful Name: "Chaos" in Serbian, signifying it as the final step in Neo-Umbrella's plan to plunge the world into complete chaos.
• Multi-Armed and Dangerous: HAOS sports multiple arms of varying sizes, spread all over its grotesque body.
• Rasputinian Death: Shot to pieces, bisected several times and repeatedly electrocuted by a mutated Piers over the course of several battles. The thing that finally kills this monster is Piers blasting it to pieces in his last moments, before what’s left is consumed by the self-destructing Neo-Umbrella facility.
• Skull for a Head: Its face is notably a human skull.
• Walking Waste Land: Its whole purpose is to spread a viral pathogen that will cause the End of the World as We Know It.
• Was Once a Man: Despite its overtly cephalopod-like traits, HAOS's head is quite clearly a human skull, its main hands appear very similar to a human's in structure, and examining its chrysalis with a sniper rifle reveals multiple human bodies embedded within. All this strongly implies HAOS is at least partly human.
• Worf Had the Flu: HAOS was prematurely released at 70.3% of its intended growth as part of Neo-Umbrella's contingency plan. What Chris and Piers fight is nothing compared to what it could be at full strength.

t-Abyss Virus

Ooze

The four Ooze variants

The most common result of a T-Abyss infection, the Ooze is the result of when a human male is infected with the virus. Aside from the average mook, Oozes comes in three other named variants: Chunk, Tricorne, and Pincer.

---

• Action Bomb: The Chunk Ooze explodes if the player comes near it, dying and taking anything else (including other enemies) out with him.
• Blade Below the Shoulder: Pincer Oozes get two large bladed arms.
• Carry a Big Stick: Normal Ooze have one or both their arms ending up in hard bony clubs they can swing at their targets.
• The Goomba: The Oozes are the most common and rank-and-file mooks the player will come across in a game filled with a wide range of monsters. None of them are particularly difficult to take down.
• Lamprey Mouth: All Oozes (except Chunk-types) have these. When they grab a player, they use them to drain their blood and other fluids.
• Our Zombies Are Different: The typical T-Abyss human infectee becomes an Ooze, a slimy humanoid who feeds via a Lamprey Mouth to attach and suck out a victim's fluids. Can come in Normal, Pincer, Tricorne or Chunk varieties. Then there's those who have a 1 in 1000 chance of the infection being slower...
• Taking You with Me: A Chunk Ooze's explosion will inflict massive damage on nearby targets. This includes, however, other B.O.W.s as well.

Scagdead

A Scagdead is a rare mutant created when the victim has a stronger-than-normal resistance to the t-Abyss virus, slowing its spread. The result is the grotesque, disproportionate body characteristic of a Scagdead, and this transformation is said to occur once in roughly a thousand hosts.

---

• And I Must Scream: What happens to those who are infected that end up turning into Scagdeads, like the Queen Zenobia's communications officer. Hosts are transformed into lumbering monstrosities with deformed human heads next to huge fanged maws that sprout out; their human halves are slightly conscious and aware of their surroundings, but have no control over their bodies and are reduced to mindless babbling. This description from their diorama sums it up best:
  "Remaining completely conscious during the process, the host gradually loses control over its body, with its mind eventually being consumed by the resulting insanity. After the mutation is complete, the unconscious mutterings of the host are eerily similar to those of a sleepwalker."
• Body Horror: The hosts' bodies are enveloped by an irregular mass of flesh and bone acting as a "new" body, turning them into bulky, grotesque monsters with pillar-like legs and large vertically opening lamprey-like maws displacing the host's head. Their left arms are emaciated with flipper-like appendages beneath, while their right arms become unnaturally muscular (albeit obscured by folds of skin) and tipped with an organic mimicry of a buzz-saw.
• Chainsaw Good: The Scagdeads' right arm ends up in a fleshy organic version of a buzz-saw.
• Dead Weight: Scagdeads are far bigger and more bloated than normal Oozes. Its description in Raid Mode missions calls it a "giant bulge of rotten flesh."
• Lamprey Mouth: The secondary head they develop is less of a head and more of a reverse cone of flesh tipped with a massive mouth.
• Madness Mantra: The communications officer has an unusual mutation that made him retain his ability to speak, but since his mind has been destroyed by the virus, it results in this.
  Mayday, mayday... This is the Queen Zenobia... emergency call number... mayday, mayday... maaaaaayyyy.... daaaaayyyyyy...
• Sanity Slippage: Based on a journal found in the room where he was locked, the communications officer suffered this as a result of serious fatigue and the viral infection that led to his eventual mutation. He became more and more delusional and confused over time to the point where he interpreted his newly grown mutated head as a friend.
• Voice of the Legion: Their voices are inhumanly deepened as a result of their mutations. The effect drops in and out, causing them to go from sounding slightly human to monstrous within seconds.

Globster

A purely irregular t-Abyss creature stemming from poor human compatibility.

---

• Blob Monster: Globsters are enormous slug-like masses of flesh that are easy to kill on land. Should you face them underwater, however...
• Meaningful Name: Aptly named after the blob-like, unidentifiable remains of sea creatures found on certain beaches.

Ghiozzo

Convenient B.O.W.s cultivated by Il Veltro. They're Arowana injected with the t-Abyss virus.

---

• Jumping Fish: Ghiozzos are t-Abyss infected fish with More Teeth than the Osmond Family. They can jump out of the water and lunge at the players on land.
• Meaningful Name: Ghiozzo is the Italian for "goby", a tiny fish.
• More Teeth than the Osmond Family: As part of their mutation, they get an elongated maw full of long teeth.

Sea Creeper

Sea Creepers, also referred to as Eve, are the result of human women infected with the t-Abyss Virus.

---

• Dem Bones: A good look at their model reveals the remains of a skull and a spine amongst the flippers, multiple appendages, and shell.
• Jumping Fish: Sea Creepers jump out of water to ambush and grab their prey.
• One-Gender Race: They're (almost) invariably what infected women transform into. Male victims tend to become Oozes instead.

Scarmiglione

Scarmiglione are hybrid B.O.W.s created through the splicing of shark DNA into the human genome through the use of t-Abyss as a catalyst.

---

• Blade Below the Shoulder: Scarmigliones have a lance-like spear made of serrated bone where their right arm should be.
• Elite Mook: By far the strongest and smartest B.O.W. found on the two ships, they have deadly defenses, hit hard, and can even survive if their legs or torsos are destroyed.
• Half the Man He Used to Be: If you inflict too damage to the Scarmiglione's torso or legs, they'll mutate further: in the former's case, the upper body is replaced by a worm-like electrified appendage that thrashes around, while in the latter's case, the jaws will protrude and it will drag itself across the floor with its arms.
• Luckily, My Shield Will Protect Me: Scarmiglione has appendages that end up as durable shields that block all incoming gunfire. They can move it to protect their legs or upper bodies, depending on where the player's aiming.
• Shark Man: Scarmigliones are the result of shark DNA being spliced into the human genetic code.

Draghignazzo

Some kind of shellfish B.O.W. or irregular mutant that shows up to Jill and Parker for a fight.

---

• The Brute: Draghignazzo has little strategy beyond charge and crush. Given the size and shell, he needs little else.
• Giant Space Flea from Nowhere: Nothing is given to this creature's origins or purpose. It just shows up for a boss battle and is never referenced before or afterward.
• Heavily Armored Mook: Covered from head to toe in heavy shell, impervious to bullets.
• Spikes of Villainy: It has massive black spikes on its back, shoulders, and arm.

Malacoda

A mass of monstrous parasitic worms created through the the t-Abyss virus. The worms in question are an infected form of a species in the Capsalidae subfamily.

---

• Achilles' Heel: The Malacoda have bulbous, big heads which are their main weak spots.
• Meaningful Name: Malacoda is the boss of the Malebranche devils (whose name was given to the other B.O.W.), and also literally means "Evil Tail". The boss is a swarm of massive parasitic worms whose appearance calls a tail to mind.
• Monster Whale: The surviving Malacoda show up riding the giant half of a mutated whale as a flesh suit to attack the sinking ship and the heroes.
• Proportionately Ponderous Parasites: The Malacoda B.O.W. are giant worms, big enough to parasite a whale.
• Puppeteer Parasite: The Malacoda can attach themselves to a bigger organism and manipulate its actions.
• Wolfpack Boss: Both times you get to fight them the Malacoda are always in a group, never alone.

Wall Blister

Barnacles infected with the t-Abyss virus.

---

• Combat Tentacles: They grow two massive, arm-like tentacles gifted with incredible strength.
• Glass Cannon: Their only form of attack is always deadly, but luckily they can't take much punishment before dropping dead.
• Savage Setpiece: Normally they're found attached to walls or ceilings, moving but non-hostile. They will come down and attack though after a certain part of the game.

Las Plagas

Las Plagas are behavior-altering macroparasitic organisms that infest other life forms and compel them to form hive-like social structures, though they leave behind some human intelligence. First unearthed centuries ago in a remote part of Europe, they became the centerpiece of the Los Iluminados cult before being sealed away by the Castellan of the region. However, generations later, Ramon Salazar unearthed them from the depths of his castle once again.

Samples of the Plaga were recovered and made their way to the bioterror black market. TRICELL would later develop and deploy genetically upgraded Type 2 and Type 3 Plagas in the African country of Kijuju. Derivatives of the Type 2 Plaga would also be used as bio-weapons in the Eastern Slav Civil War incident.

---

Common

The parasites

• Big Creepy-Crawlies: The more mature Plaga look sort of like bugs and other creepy crawlies; centipedes, worms, spiders, leeches, and other squiggly things you'd find under a rock. They are even classified as parasitic arthropods, though they are way, way bigger than any real-life one.
• Body Horror:
  • Plaga expose themselves in response to damage. Most generally emerge from the neck, bursting the head in the process, but upgraded versions can burst through the entire upper body and create a massive jaw on human legs.
  • Dominant Strain Plaga take everything bad about how normal Plaga emerge from their hosts, turns them to the top rank, and customizes them to how their hosts want. Mendéz walks around with an inhumanly long and fully exposed spine as well as tentacle spikes grown out of his shoulders, Salazar (merged with the Queen Plaga and a Verdugo) turns into a monstrous tentacle head that grows out of a flesh wall, Krauser's arm turns into a giant scythe, Saddler has legs that are bigger than his entire body burst out of his neck, carrying his face with an eye in the mouth.
• Combat Tentacles: The "Plaga Type 1 A" from the European outbreak and the "Cephalo" Type 2 from the African outbreak both wield a strange combination of this and Epic Flail. The Type 1 A is a shapeless mass of tentacles, with one huge tentacle tipped with a serrated bone blade, which it whips around to hack Leon with. The Cephalo is a tentacle/centipede hybrid that ends in jagged spurs of bone; it spins itself around and around in constant arcs as the host strides forward, slashing at anyone in its way.
• Flawed Prototype: In Damnation, the Plaga strain being developed in the Eastern Slav Republic is extremely flawed in comparison to other variations. Those infected with the submissive strain are closer in behavior to Zombies, demonstrating less coordination and intelligence than the Spanish or African strains. Even the Dominant strain isn't free from major flaws, granting the host Hive Queen abilities but eventually turning them into regular Ganados. Ada is openly dismissive of this strain, calling it a defective product.
• Hive Queen: The Dominant Strain Plaga, which commands the obedience and loyalty of all subordinate strain Plaga — and thusly their hosts.
• It Can Think: What sets them apart from zombies is the fact that they have all the intelligence of a human, wielding weapons and acting strategically. They'll do things like flank you, trap you in pincer attacks, flush you out of cover, and run interference while their cohorts snipe at you from a distance.
• Lovecraftian Super Power: Hosts of a Dominant Strain Plaga can command the obedience of lesser Plagas and often have far greater strength and durability, as well as a One-Winged Angel form of truly horrific appearance.
• Made of Iron: Thanks to the Plagas' coopting of their hosts' nervous systems, those under a Plaga's control are far more resistant to pain and injury than is normally the case. Shooting somebody in the head is normally something of an instant-off switch, but a Plaga carrier could react to a bullet in the forehead as though you'd merely beaned them with a tennis ball.
• Meaningful Name:
  • Las Plagas itself literally means "the plagues".
  • The various Type 2 Plaga in 5 receive these kinds of names from Swahili; the spider-like unhosted adults are referred to as "Bui Kichwa" ("Big Spider Head"), the head-replacing tentacle-like "Cephalo" ("Head", and short for the Kenyan root vegetable "Cephalopentandra"), the flying bat-leech "Kipepeo" ("Butterfly") and "Duvalia" (after a kind of African carrion-flower).
  • Plaga forms are given Spanish names in the 4 remake; the tentacle blade form is called "Guadaña" ("scythe"), the mandibled jaw form is called "Mandíbula" ("mandible"), and the fully grown form is called "Araña" ("spider"). The newly added broken neck early game Plaga form is called "Desnucado" ("broken neck").
• Parasite Zombie: The obvious result of a host organism fully parasitized with Las Plagas.
• Parasitic Horror: Given that the Plagas are used as bioweapons for terrorism and as an attempt of world domination.
• Puppeteer Parasite: As Plaga take over the brain and nervous system as part of their parasitism, they alter the host's behavior, causing them to descend into savage barbarism. In the remake, the adult spider-like Plaga, or "Araña", can also jump onto the backs of Ganado and literally puppeteer them to attack manically.
• Raising the Steaks: Las Plagas doesn't just use humans as their hosts. Animals like wolves, dogs, salamanders, and even B.O.W.s are fair game for the Plagas to parasitize on.
• Red Eyes, Take Warning: The eyes of a Plaga's host turn bright red once it has control. When a Type 2 Plaga infects a new host, they actually bleed from their eyes, nose, and mouth as a side effect of physical control.
• Symbiotic Possession: The Plagas have their own personalities independent of their hosts, and while many tend to subjugate them to their will and that of the Dominant Plagas in the area, some hosts and parasites have compatible enough outlooks to allow a more mutualistic bond where the parasite merely offers its abilities to augment the host rather than control them directly. This is most-often seen with higher-ranking members of Los Iluminados since their religion allows the strongest parasites to propagate, though rarely the Plagas will do it out of a sense of sympathy rather than pragmatism.
• Technically-Living Zombie: A Plaga's host displays some zombie-like traits, such as resistance to pain, mindless violence towards those not infected, bloodlust, savage and impulsive behaviors, and a hunger for flesh, but are still living creatures, just subsumed by the bestial urges of the parasite within them. This is slightly more pronounced in Type 2 Plaga hosts, who have an instinctive directive to "spread the infection" as far and as fast as possible.
• Token Heroic Orc: An abnormality that is only brought up in Luis' documents is that the Plagas can apparently resist the Dominant Strains, as was the case with Luis', which willingly killed itself rather than force Luis under its influence.
• Weakened by the Light: Ultraviolet light is anathema to Plagas. Consequently, Type 1s won't expose themselves until night falls. Type 2s have had this trait weakened and so will operate in the day without harm. Both types, however, cannot withstand the concentrated light released from a Flash Grenade, making these Trick Bombs a One-Hit Kill weapon against them. When Ashley is forced to progress through an area covered by Armaduras in the remake, both her lantern and pockets of the mausoleum emit a blue flame that causes them to be paralyzed for as long as they are exposed to it.

Human hosts (general)

Ganados, Majini

Upper: A pack of village Ganados; Lower: Typical Majinis

Ganados (literally "The Herd" or "The Cattle") and Majini ("Wicked People") refer to most of the human hosts of the Plaga; the former are largely the victims of the Los Iluminados in Europe, the latter victims of TRICELL and Albert Wesker in Africa.

---

• Adaptational Badass:
  • The Villager Ganados get an extra Plaga form in the remake, Ganado Desnucado, where the Plaga takes over the host's body but doesn't fully burst out of their neck, leaving the head hanging on the body sideways.
  • The "Priest Ganados", red-robed Zealots from the castle area that wear skulls for helmets, are simply rare cosmetic reskins in the original game, but become mini-bosses in the remake, with greatly expanded healthpools that make them as tough as the infamous Chainsaw Villagers, an Interface Screw attack, and the ability to activate the plagas in any nearby ganados.
• Ax-Crazy: Ganado and Majini, for the most part, are not actual zombies (per se) as they are possessed people driven by negative emotions taken up to eleven. When they don't feel threatened to enter a psychopathic frenzy, they're capable of relative civility and regular lives amongst each other. Their sense of reasonability, however, wildly varies from individual to individual: the ones that live in Bitorez Mendéz's mansion are almost normal, whilst some of the villagers live in inhuman squalor and self-inflicted violence. The remake explicitly notes in a file that the plaga infestation causes varying levels of brain damage.
• Bald of Evil: The Zealot Ganados, when not wearing hoods or helmets, are invariably shaven bald and tattooed on the skullcap as a sign of their devotion, which adds to their unsettling appeal. This includes the female Zealots, in the remake.
• Body Horror: The Marshland Majini, the members of the Ndipaya and Sodibaya tribes infected with the experimental Type 3 Plagas, play this straight, with corpse-green skin, flayed-looking arms, hearts that have swollen until they visibly burst through the chest, and cheeks that rot away to expose a permanent rictus snarl of teeth.
• Brutish Character, Brutish Weapon: The Brutes wield sledgehammers as their primary weapon and their swings are so strong that Leon will have to evade rather than parry it with a knife.
• Drives Like Crazy: It seems that being infected with a Plaga has made Majini drivers very, very reckless to say the least. The first driver attempts to run over Chris and Sheva without a care whether the driver falls off a bridge gap while swerving around, and the second driver barely avoided falling off a cliff in an attempt to release and sic a B.O.W. inside its cargo container on the duo (and said driver is dead when he smashed his head on a steering wheel after he made a sudden sharp turn).
• Elite Mooks:
  • Salazar's cult and Saddler's combatants are much smarter than the villagers. The former being the first to use ranged weapons (a crossbow which was later used by the Town Majini), carry far deadlier weapons like flails and scythes that give it more range, and carry wooden shields that require players to expend ammo to break them. The latter, in addition to carrying the same weapons and equipment as the cult also come with shock batons that leave players stunned for a following attack, wear ballistic helmets that render headshots ineffective (helmets are only worn by cult leaders), and carry RPG's more often (it is only used by a few select members of the cult).
  • The Base Majini from 5 top the aforementioned combatants by virtue of being modernized; they carry small arms (an AK-74 assault rifle), carry ballistic shields (as opposed to a wooden version) that make it impervious to anything short of an explosive, and can lob grenades (that Saddler's combatants cannot do) making them more deadly in combat.
• Gas Mask Mooks: A good deal of Saddler's non-specific militants and some of TRICELL's mercenaries wear gas masks.
• Giant Mook:
  • The aptly named "Big Man Majini" and (exclusive to REmake 4) "Brute Ganado" are a mundane example, possessing a muscular and heavier build compared to their brethren.
  • J.J. and his Majini counterpart are bigger than the "Big Man Majini" and their build makes them strong enough to use gatling guns as portable weapons.
  • The appropriately named "Giant Majini" are chieftains of the Ndipaya Tribe and their imposing physique are a result of being infected with the Type 3 Plaga, and are even taller than J.J. and his Majini counterpart.
  • The 2023 remake replaces J.J. with the Brute Ganados, who, while smaller than J.J., fulfill a similar role, wielding either sledgehammers or arm-mounted homemade machine guns.
• Gonk: None of them are lookers, but the Big Man Majini is very ugly even by average standards.
• Jerkass: Even discounting their attempts at murdering any and all visitors, the Ganado are just plain verbally inhospitable. The first one that Leon meets 'greets' him by saying "What the fuck are you doing here? Get out, bastard!" in Spanish. They also often call him an "imbecile".
• Large Ham: The Instigator/Agitator Majini is fittingly very theatrical and loud to inspire his brethren into action.
• Luckily, My Shield Will Protect Me: The cultists, militaristic-based enemies, and tribal Majini sometimes carry wooden shields or riot shields that make it difficult to harm them unless the player aims for their legs.
• Meaningful Name: In Resident Evil 5 and Resident Evil 4 (Remake), the plaga forms are all given names in either Swahili or Spanish that are one-word descriptors of their dominant physical trait.
• Men Are the Expendable Gender: Female Ganado and Majini only appear in the first (Village or Town) area of both 4 and 5, with the later areas having only male hosts. Concept art reveals that there were plans to include female Zealot Ganado in the original RE4, but they were cut, with RE5 justifying the lack of female Maijini outside of the town being due to the use of a different type of plaga that is lethally incompatible with female hosts. The remake of RE4 walks this back, including female Zealot Ganado in the castle and leaving only the Mercenary/Militia Ganado on the island as exclusively male.
• Politically Incorrect Villain: The rather unique Majini, dubbed “Instigator/Agitator Majini” is an Islamic terrorist that spouts (all of them in Swahili) xenophobic spiel against the ethnic minorities in the Kijuju region and rallies his fellow Majini into committing genocide on them. Based off Plaga retaining their host’s personality traits and memories, it’s likely this is what he was like even before infection.
• Rock Beats Laser: The majority of them are armed with melee weapons and (bar the Base Majini) lack access to small arms, and had to resort to using crossbows for ranged attacks (or a warbow for the wetlands variant). This doesn't diminish on how dangerous they can be (especially on higher difficulties) due to their numbers, being able to take a gunshot wound that would normally incapacitate an unarmored target (if not kill them outright), and can break into dangerous forms if not defeated with a melee prompt that kills them instantly.
• Scary Black Man:
  • J.J. fits this archetype, being a large and heavily-armed Ganado with a dark skin complexion.
  • This trope is a given for the Majini, being comprised mostly of African men driven insane by a parasite famous for Body Horror.
• Sir Swears-a-Lot: The Ganado are quite foul-mouthed, often muttering "cabron" ("bastard") and "mierde" ("shit") under their breath.
• Smarter Than They Look: Majini and Ganado as a whole are capable of behaving more or less normally until they’re spurred into action and go Ax-Crazy. Even the Tribal and Base Majini, who’ve been most affected by the Plaga, are not exempt, with the former capable of acting out their tribal customs despite devolving into open war with each other and outsiders, and the latter operating like functional, if reckless, trained soldiers.
• Sinister Scythe: The weapon of choice for many of Salazar's cultists are sickles and scythes.
• Technically-Living Zombie: They’re all still living humans infected with Las Plagas parasites, and while they all possess varying degrees of resistance to pain and injury, they can still be put down by anything that would kill a normal human. Played with in that after the parasite has fully matured and taken control, the host's body starts showing clear signs of decay over time.
• Turns Red:
  • In Resident Evil 4, after reaching a point in the game where night falls, Ganado now have a chance to sprout their plaga upon taking sufficient damage, which gives them a new pool of health and much more dangerous attacks.
  • Resident Evil 4 (Remake) tweaks the formula by adding a new plaga variant, the "Desnucado", who will appear during the day. It also has a new mechanic where the Ganado will usually (but not always) fall to the ground and begin writhing before their plaga manifests, giving the player a chance to kill them by getting close and stabbing them with an action command, as opposed to just bursting out like in the original.
  • In Resident Evil 5, Majini can also sprout their plaga upon taking sufficient damage, but their genetically tweaked strain is resistant to sunlight, so they start doing it much earlier in the game.
• Underground Monkey:
  • Aside from different statistics, voice lines, and some of them having weapons unique to their kind (scythes for cultists and stun rods for the combatants), the three Ganado variants (Villagers, Cultists, Combatants) all fight exactly the same.
  • Zealots have a rare variant dressed in red robes and an animal skull helmet, often nicknamed "Priests", who despite looking different are no tougher or more dangerous than a regular Zealot. The remake changes these into Elite Mooks instead.
  • The Majini in RE5 have unique appearances and weapons across the different areas.
• Unfriendly Fire:
  • Dynamite thrown by a Ganado will kill any other Ganados that wander into the area of effect.
  • The 2023 adds Ganados armed with molotov cocktails, which are as indiscriminate as the dynamite.
  • In the 2023 remake, Dr. Salvador and a Brute can kill their own allies with a wild swing from their chainsaw and sledgehammer respectively.

Chainsaw Man

AKA: Dr. Salvador

^{Chainsaw Sisters}

^{Chainsaw Majini}

As the name implies, the Chainsaw Man is a chainsaw-wielding Ganado wearing a distinctive potato sack over his head. Introduced in 4 and dubbed "Dr. Salvador" via localization, he has a Dual Boss counterpart, the Chainsaw Sisters — dubbed "Bella Sisters" — and a non-canonical "Super Salvador" counterpart in the Mercenaries game mode.

---

• Adaptational Skill: In the RE4 remake, Dr. Salvador has a second attack method where he swings his chainsaw in a frenzy as he approaches Leon, which is a move only seen before by the Super Salvador in the original RE4 mercenaries mode.
• Adaptational Ugliness: While we never fully saw his face, in the original RE4, Dr. Salvador has at least a normal face from what see of it from the holes in the bag. In the remake, it's a lot more gross, possibly skinned, and his eyes are bulging and manic.
• Adaptational Wimp: They're still formidable foes in the RE4 remake, but since Leon is now able to parry their chainsaw attack, getting backed into a corner by a chainsaw wielder is no longer a death sentence as it was in the original. Should Leon or Ada be using an unbreakable knife, then they're next to harmless.
• Ax-Crazy: Even relative to the usual Ganados and Majini, the Chainsaw-wielding enemies are evidently super unhinged based on their blood-soaked appearances and trademark. The Chainsaw Majini moreso as they laugh like a maniac will swinging it.
• The Berserker: If a Chainsaw Majini goes down for the first time, there is a chance that they will get back up and wildly swing their chainsaws around in a mad frenzy while advancing slowly at you. Fortunately, they are no longer capable of instantly killing you at this state.
• Breakout Character: As aforementioned, the original Chainsaw Man is considered one of the most iconic enemies in the franchise, to the point that most games after RE4 have their own chainsaw (or any kind of power tool) wielding enemy (Chainsaw Majini, Scagdead, Ubistvo, Mutated Pedro, Jack Baker, Mia Winters, and Soldat). Outside the series, the Chainsaw Man was a direct inspiration for the now-famous chainsaw bayonet-equipped Lancer Assault Rifle in the wildly successful Gears of War series.
• Chainsaw Good: They carry these owing to their namesake, and it adds to how dangerous and brutal they can be as any hit from them is an instant death by beheading (unless you are away from them in 5 where it only results in being incapacited).
• Dual Boss: The Bella Sisters are always seen as a duo, except for one appearance in the RE4 remake in the mines where only one shows up, but alongside a Dr. Salvador.
• Elite Mooks: The Chainsaw Man and his derivatives are bullet sponges that don't flinch easily and are only capable of a One-Hit Kill if they get up close.
• Impaled with Extreme Prejudice: Unlike in the original game, in the remake, they slash Leon's shoulder, and then jam the chainsaw into his chest, and out the other side while it's still running. It's also a One-Hit Kill.
• Laughing Mad: A signal when a Chainsaw Majini starts to swing their trademark weapons at you is their distinct, maniacal laughter. Of course, there is a chance that they may not even laugh when swinging their chainsaws.
• Made of Iron: They're a lot more durable and less prone to flinching compared to the average mook.
• Mighty Glacier: They're never particularly fast, but their only attack is an instant kill, or instant "dying state".
• Not Quite Dead: If their chainsaw is still running after they go down, that means they will get back up later.
• Off with His Head!: Their memorable and iconic One-Hit Kill move in the original.
• Skippable Boss: In the original, the encounter with the Bella Sisters can be skipped entirely by simply choosing to go through the canyon guarded by another El Gigante instead. You can still go back and do both for more treasure, however. This is no longer the case in the remake, as the second El Gigante was removed in favor of a mandatory fight with the sisters.

Garrador

Garrador are failed Plaga-based human B.O.W.s. Having gone blind and mad from the augmentation process, Salazar keeps them locked away until he desires to sic them on undesirables (i.e Leon). Armed with massive claw gauntlets, Super-Strength and a Healing Factor, Garradors are among the most dangerous enemies in 4.

---

• Handicapped Badass: Those monsters are completely blind, but still much more of a threat than most of the other cult members.
• Lightning Bruiser: Insanely fast and powerful with various one-hit kills. They are balanced by their blindness, however, hindering what could be so much worse.
• Logical Weakness: Like the Lickers, they rely on sound to locate their prey, and it's possible to shoot bells to make them direct their attention away from Leon so that he can attack them from afar.
• Meaningful Name: Garrador roughly translates as "the clawer", as they fight with claws.
• Mini-Boss: The Garradors are armored Lightning Bruisers who can only be hurt if you Attack Its Weak Point.
• Sense-Impaired Monster: They have had both eyes sewn shut, rendering them blind. They have increased hearing and will hear Leon if he runs, gets too close, fires his weapon, or smashes a crate, but you can also use this to your advantage: you can fire and leap out of the way to take aim at their exposed back, and a lot of rooms have conveniently-placed bells that can be fired on to lure it as well.
• Unfriendly Fire: Being blind, they cannot distinguish between friend or foe and will violently slice and eviscerate everything they perceive as a threat, this includes the cultists as they have a tendency to make some noise when pursuing Leon.
• Wolverine Claws: Garradors are armed with a massive set of wrist-mounted claws.

Novistador

A bugman mutant monstrosity. They are frequently encountered within the dregs of Salazar's fancy castle estate.

---

• Acid Attack: They can spit corrosive liquid and their fatality has them melt Leon's face with a point-blank spray.
• Airborne Mook: They mostly move and attack by flying around, which is helpful as the sound of their buzzing wings can give out their position.
• Ascended Extra: They are much more prominent enemies in the remake. They appear earlier than they do in the original, there are several files detailing the process of their creation, and they even show up during the final boss fight.
• Big Creepy-Crawlies: The Novistadors are Plaga-based insect hosts which look something like a locust, something like a mantis, and something more like something out of an entemophobe's nightmare. They're giant flying bugs that can turn invisible and melt your face off with Hollywood Acid to eat your brains.
• Fragile Flyer: Flying Novistadores are more mobile than their land variant, but also much more fragile, as a single shot from any weapon will kill them instantly.
• Half-Human Hybrid: In the remake, a file detailing their creation explains that they are conceived in a human womb through the use of some black liquid originating from the Las Plagas.
• It Can Think: Despite looking like giant bugs and nothing more, they seemingly can understand and carry out orders, as seen when one of them kidnaps Ashley.
• Meaningful Name: Novistadores literally means "The Unseen", as they are invisible.
• Nothing Is Scarier: Little is known of how they came to be. All that's said in the original game is they were the result of especially horrific human experimentation that involved insects.
• Was Once a Man: Apparently, these things were once human. Not so much in the remake.

Armadura

Plaga housing ancient suits of armor. They remain dormant in obscure portions of Salazar's castle, namely his dungeons.

---

• Armor Is Useless: They're animated suits of armor but not all that durable, which can probably be justified by how ancient they are. They are, however, difficult to stagger due to being non-sentient. Averted in the remake, where they’re completely invulnerable unless you shoot the exposed plaga.
• Dark Is Evil: The tougher versions of them are colored black instead of silver.
• Elite Mook: The remake includes a golden-armored one as an optional mini-boss and target of one of the Merchant's requests.
• Meaningful Name: Armadura means "armor".
• Mighty Glacier: They're lumbering and swing their weapons slowly, but they hit extremely hard.
• Nobody Here but Us Statues: They normally stay still and pretend to be a normal suit of armor until a prey comes.
• Puppeteer Parasite: Suits of old knight armor controlled by Plaga. Destroying or harming them will cause the parasites to erupt and fight on their own.
• Wolfpack Boss: After Ashley's level, they'll only reappear one more time to obstruct Leon in a gauntlet featuring waves of them. The remake flips this around by having Leon fight a gauntlet of them first before Ashley's level.

Regenerador / Iron Maiden

^{Iron Maiden}

The Regenerador and Iron Maiden are considered Los Iluminados' first step into entering the B.O.W trade successfully. As the name implies, these monsters are renowned for their regenerative capabilities, being nigh-invincible unless their Plagas are completely destroyed.

• Adaptational Badass:
  • Zigzagged with Regeneradors in the Remake. They're much faster than they were in the original, and quicker to leap when their legs are blown off, making it harder to hit their Plagas. On the other hand, you doesn't need to rely on the Biosensor scope as much to find and take out the Plagas, as damaging their skin enough will reveal their locations and the Biosensor scope can now be mounted onto Leon's LE-5 submachine gun, which also boasts high penetration, making misses less punishing and saving on rifle ammo.
  • Zigzagged with the Iron Maidens in the Remake. Like the Regeneradors, they're faster and quicker to leap about when their legs are blown off, and they've gained a new Spike Shooter ability that makes them a threat from further away, complete with a final kamikaze burst upon death. However, they only have a single plaga, which is always located in their head and can be seen glowing inside its mouth, which makes them more Glass Cannon compared to the originals.
• Attack Its Weak Point: The only efficent way to kill them is to destroy the 2 to 5 Plagas inside of their bodies, which can only be seen ether with the Biosensor, or in the Remake damaging their skin enough to expose them.
• Body Horror: Regeneradors and Iron Maidens have mutated into Monstrous Humanoids with rubbery grey skin that pulsates, appendages that they can extend to inhuman lengths, triple-jawed, otherwise featureless faces, and they self-repair by growing Plaga tentacles. Not to mention, the Iron Maiden literally has spikes coming out of its every single skin surface.
• Boss in Mook's Clothing: The second-last of the Merchant's Requests in the remake is to hunt down a "strong mutant" in the specimen lab. It's an Iron Maiden with seven plagas.
  • A second "strong threat" Iron Maiden just shows up unceremoniously in Ada's Separate Ways campaign in the Remake after Ada has almost completed her circuit through the specimen labs.
• Defeat Equals Explosion: When a Regenerador or an Iron Maiden is killed, their body swells madly and then explodes in a shower of gore and chunks of meat. In the remake, the Iron Maidens weaponize this, as it triggers a final burst of their Spike Shooter ability.
• The Dreaded: Even the Los Iluminados seem unsettled by these things, since they cause mass casualties every time they break containment and even just when being transported from place to place. Leon himself is noticeably unnerved by the monsters, shakingly asking what they are.
• Extreme Omnivore: In the remake, one of them has swallowed a wrench, which you can see stuck inside of it by using the biosensor scope. In Separate Ways, one swallowed one of the Ornate Beetles you have to sell for a sidequest.
• Glass Cannon: Iron Maidens in the remake only have a single plaga that is always located inside of their head, compared to the three or four randomly placed plagas they would have in the original game; this means they are much easier to bring down. But their powerful melee attacks and Spike Shooter ability means they can also deal a lot of damage to Leon if he's not careful.
• Gone Horribly Right: In the remake, Leon finds a journal from the Regeneradors' creator, in which he brags about how indestructible they are and dismisses a colleague who points out the dangers of the project as a fool. The final entry?
  "The subject went wild and escaped from its cryogenic tank. I was the real fool."
  • It's also indicated that Los Iluminados has a hell of a time trying to re-contain them every time they break out. Worse yet, their hardy bodies eventually developed a resistance to the one thing that did pacify them: freezing temperatures.
• Good Thing You Can Heal: In spite of being nigh-unkillable, their limbs are in function exceptionally fragile. While it isn't a crippling weakness, it does mean that a player lacking the necessary scope to precisely target the parasites can at least momentarily incapacity them by hitting a leg. Just be ready for them to start flopping after you.
• Healing Factor: This is where their name comes from. The Regeneradors and Iron Maidens can regrow damaged parts of their bodies at an alarming rate. While not hard to knock these things down, the trick is getting them to stay down.
• Hell Is That Noise: Their distinctive raspy breathing, which is known to unsettle even hardened veterans of the series.
• Jiggle Physics: For some ungodly reason, Capcom gave the Regeneradors jiggle physics in the remake.
• Made of Plasticine: An x-ray image of a partially-transformed Regenerador's skull in the remake shows that their bones are fractured and mostly held together by muscle mass. This is likely what allows for their stretchy limbs and incredibly fast Healing Factor, but also has the side-effect of making their bodies very soft. Simply parrying results in them losing whatever arm they were attacking with, but they don't really need to care thanks to their regeneration powers.
• Mini-Boss: The Regeneradors and Iron Maidens have a Healing Factor that makes them almost impossible to kill without specialised equipment and precise aim (or explosives). A black-skinned Iron Maiden appears in the remake as the target of a late-game sidequest and in Separate Ways to either fight or run from.
• Rubber Man: Both can extend their arms to ludicrous lengths to grab you.
• Spike Shooter: Iron Maidens are covered in spikes, which can extend to great length when hurt or if they want to attack. In the original game, they zigzag the trope in that they extend the spikes to a considerable distance, but don't fully launch them, so the player can avoid them by staying far enough back. In the remake, they can properly shoot them at you.
• Taking You with Me: In the remake, Iron Maidens launch spikes flying like deadly shrapnel when they explode upon death.
• Turns Red: In the remake, Regeneradors that have all their plaga shot may sometimes transform into Iron Maidens rather than dying. It's unclear if this is scripted or if it's random chance, as with the Ganados releasing their plaga.
• Vader Breath: You can hear their raspy, creepy breath long before you see one. It has been compared to a man breathing with a slit throat.

Kipepeo

A successful Plaga-based B.O.W produced by TRICELL. Simple but efficient aerial predators mainly useful as anti-aircraft.

---

• Airborne Mook: They are fly around and require ranged weapons to ground them.
• Big Creepy-Crawlies: They're B.O.W butterflies.
• Boring, but Practical: They lack any flair besides being flying Plaga, but they are all-around effective and cheap B.O.W.s.
• Meaningful Name: Their name comes from the Swahili word for "butterfly."

Bosses

Del Lago

A massive Plaga-infected amphibian monster that the Ganados appease by feeding corpses. It serves as the first boss of RE4 when Leon has to cross the lake it occupies.

---

• Amphibian at Large: Granted, there are giant salamanders in real life, but Del Lago outshines them by dint of being a massively mutated monstrosity.
• Amphibian Assault: Del Lago is basically a voracious mutated salamander.
• Bizarre Alien Limbs: The infection has rendered its legs small and useless, forcing it to live in the water to sustain its weight.
• Easter Egg: If Leon shoots at the lake several times before riding on the boat, Del Lago will pop out from the lake and devour him.
• Fed to Pigs: Fed to a giant salamander in this case. Before the boss battle, Leon witnesses two Ganados feed it with the body one of the cops who accompanied him.
• Meaningful Name: "Del Lago", a giant aquatic monster encountered in the village, means "from the lake" in Spanish.
• Sea Monster: Lake monster in this case. It is a salamander that was infected with the Las Plagas, turning it into a gargantuan monster. Unable to keep in under control, the cult placed it in the lake.
• Wake-Up Call Boss: It's the first boss and major challenge in 4, illustrating the bosses are going to be much more dynamic and creatively distinguished from the rank and file enemies.

El Gigante / Ndesu

Top: El Gigante; Bottom: Ndesu

El Gigantes are unintended B.O.W.s that resulted from Plaga growing certain human hosts to gigantic proportions. Though the exact means of producing them are not too elaborated upon, TRICELL obtained data on the monster to recreate them in the form of the Ndesu.

---

• Awesome, but Impractical: El Gigante is the first Plaga B.O.W. and is proven to be a success in the field. However, these creatures are hard to control and a single El Gigante requires a lot of food to be satisfied. As a result, Los Iluminados only possess four of these.
• Beard of Evil: Ndesu does very little to distinguish itself from its predecessor besides having a thick beard.
• Big Eater: A journal found in the remake states that an El Gigante has an enormous appetite. The one at the quarry ate a dog when its only a few months old and within a year, it had nearly eaten all of the village's cows until a red-robed zealot put it to sleep.
• Body Horror: Ndesu's body is covered in crudely-stitched gashes, from which huge leech-like Plagas burst forth after it takes enough damage.
• Creepy Souvenir Ndesu adorns its loincloth with the skulls and dead bodies of its victims.
• Dual Boss: Later in the game, you have to fight two Gigantes inside a room deep in the castle. However, you can take precautions to get rid of one of them, making the battle easier. The downside is that killing it the easy way (by dropping it into lava) destroys the reward you would get for killing it the hard way.
• Dumb Muscle: The Plaga has caused its host to grow to enormous size, but in the process the host's personality and consciousness are all but erased, leaving a mindless brute.
• Enfante Terrible: Played for Horror. The remake of 4 reveals that an El Gigante is the result of a rare mutation that can occur when a Plaga infects a child. Most children simply perish due to their bodies being unable to handle bonding with the parasite, but those few that do survive become a monstrous El Gigante.
• Meaningful Name: El Gigante is simply "the Giant" in Spanish. It's also slightly misleading, as despite being called "El", there are at least four of them.
• Our Giants Are Bigger: The ogre/giant-like El Gigante and Ndesu are massive, hugely strong, and dangerously violent Plaga hosts.
• Puzzle Boss: In each encounter, you can fight them head or you can use a gimmick to gain an advantage: in the first battle, if you rescued the dog in the bear trap then the dog will come to your aid and distract the monster, in the second encounter you can shoot some traps to drop boulders on the Gigante and in the final encounter, you can drop one of the two monsters in a pool of magma.
• Recurring Boss: After the initial scripted boss fight, different El Gigantes are fought throughout the course of 4. Only Ndesu is one-of-a-kind and never seen after 2-3 in 5.
• Skippable Boss: The second Gigante in the original 4 can be skipped entirely by going through the fortified area with the Bella Sisters instead. Nothing is stopping you from going back and doing both, however. This encounter was removed in the remake.
• Telephone Polearm: The first Gigante you fight picks up fallen trees and uses them as weapons.

Verdugo

A highly unique intelligent Plagas-based mutant. Only two are known to exist, serving as Salazar's bodyguards.

In the remake, the red-robed Verdugo is the only "proper" Verdugo in the game; the black-robed "Verdugo" has been recharacterized into Pesanta, see below.

---

• Adaptational Explanation: In the remake, it's finally revealed where the Verdugos came from. One of Salazar's servants was conducting gene-splicing experiments with human and arthropod DNA; the Novistadors (which he called U-II) were an early iteration of the project, the Pesanta (which he called U-III) was the second iteration, and Verdugo the final iteration, created using himself as the base.
• Attack Its Weakpoint: In the second phase of the third fight with Pesanta, the parasite tail takes over to fight Ada, exposing a glowing weakspot on its middle segment and on the tip of its other end. It's not necessary to shoot these, but they will deal considerably more damage than shooting other parts on its body and can stagger it.
• Beware My Stinger Tail: They have long, extensible tails tipped with a single double-edged blade they can use to slash and impale Leon.
• Bring It: The remake's red-cloaked Verdugo will occasionally beckon at Leon with his left hand after being attacked, apparently to taunt him.
• Creepy Long Fingers: Their hands spot extremely long and thin multi-jointed fingers similar to spider legs.
• Co-Dragons: They serve as Salazar's personal bodyguards, and are both far more formidable than him in combat.
• Divergent Character Evolution: In the original game, Salazar's bodyguards were pretty much interchangable besides the color of their coats. They initially seem that way in the remake as well, but reveal that they are drastically different from one another as Leon and Ada fight against them.
• Finger Wag: If Leon strikes the Verdugo with an ineffective attack, he will do this to mock him before resuming his assault. The remake ups this to a Bring It gesture.
• Fusion Dance: In the original, the black-cloaked Verdugo ends up fusing with Salazar to do battle with Leon alongside its master.
• Hoist by His Own Petard: In the remake, a note reveals that the liquid nitrogen showers you use against the Verdugo were installed at his own request when he was human.
• In the Hood: When introduced, they are wearing massive hooded robes which hide most of their features.
• It Can Think: The Verdugos are unusually intelligent for B.O.W.s, showing the capacity for restraint and enough intelligence to understand complex orders. They even display a level of ego and emotion, such as their taunting of Leon should he use an ineffective attack.
• Kill It with Ice: The Verdugo can be severely weakened by knocking down one of the nitrogen tanks next to him to spray him with the freezing chemical, making him vulnerable to the rocket launcher for a One-Hit Kill.
• Lightning Bruiser: The Verdugo sent to kill Leon demonstrates they are the strongest, most durable, and fastest humanoid enemies in the fourth game.
• Lodged-Blade Recycling: In the original game, after Leon tosses his knife into Salazar’s hand to shut him up, one of his Verdugo bodyguards pulls it out and tosses the blade back to sender, which will actually kill Leon unless he dodges it.
• Made of Iron: Can actually survive being shot with a rocket launcher... unless you can weaken him first.
• Meaningful Name: Verdugo means "executioner", a Name To Run Away From Really Fast that is fitting for an ultra-powerful monster sent directly to kill Leon.
• Named by the Adaptation: A note in the Resident Evil 4 Remake reveals that the Verdugo that chases Leon was once a male castle servant named Isidro Uriarte Talavera, who created both Pesanta and the Novistadors.
• Optional Boss: The red-robed one attacks Leon after powering on the generator in the sewer system beneath Salazar's throne room. He can either try and kill the Verdugo... or Hold the Line and run away on the elevator as soon as he gets a chance. Killing him is worth it at the very least, as the Verdugo drops the Crown Jewel; when combined with the Crown and Royal Insignia treasures, it forms the Salazar Family Crown, the most expensive treasure in the game sold at 400,000 pesetas. In the remake he drops his former human self's gold monocle instead, which is worth 30,000 pesetas.
• Scorpion People: Their shiny black chitinous skin, mandibles, and spiked tail call a scorpion to mind.
• Vader Breath: They have recognizable, ominous raspy breath.
• Was Once a Man: The remake has a note that reveals that the Verdugo that chases Leon was originally a castle servant and scientist named Isidro Uriarte Talavera.
• What Happened to the Mouse?:
  • Should the player escape the first Verdugo rather than kill him, he egregiously never appears again despite being one of Salazar's two elite guards. It's heavily implied that canonically Leon is supposed to kill him.
  • In the remake, Salazar no longer fuses with his second Verdugo to morph into his boss form, with the black robed Verdugo completely disappearing after Salazar's first scene. The Separate Ways DLC reveals that the second Verdugo, named Pesanta, decided to make Ada Wong her target after Ada freed Luis from his cell. Pesanta hunted Ada throughout most of the DLC until she finally killed her while Leon had his duel with Krauser.
• Xenomorph Xerox: They look and act much like the creatures from Alien with their vaguely insect-like bodies covered in an almost mechanical-looking exoskeleton, long segmented tail they use to impale you with, and their habit of crawling through vents to ambush you from. Funnily enough, the Verdugo combines this trope with the aliens' long-standing rival, the Predator, with its more humanoid head sporting mandible jaws.

Pesanta

^{Click here for her mutated form.}

The black-robed "Verdugo" in the remake, actually a proto-Verdugo created using biological fusion of Salazar's housekeeper and a variety of Plaga organisms. Unlike in the original, she no longer fuses with Salazar to create his One-Winged Angel form. She is revealed in the Separate Ways DLC to have spent her time hunting down Ada.

---

• Adaptation Expansion: In the original 2005 game, U3 only showed up for a random boss fight halfway through the island section and had no context for its existence, while the black-robed Verdugo was The Unfought due to its Fusion Dance with Salazar. In the remake, both the main game and the DLC explain Pesanta's origin as Salazar's maid, and she is a Recurring Boss throughout the latter.
• Black Cloak: She wears a hooded black robe with a bit of red at the bottom. The game even refers to her as "Black Robe" in the mission objectives.
• Body Horror: Nowhere near as much as the original U3, but she does now have an exposed brain with what seems to be a ribcage wrapped around it.
• Body of Bodies: Not as overt as the original U3, but a note by Uriarte does imply that he had to merge the human Pesanta with another organism to get the transformation into U-3 to work.
• Bring It: Just like Verdugo, Pesanta also rarely beckons with her claws to taunt Ada during their second duel.
• Co-Dragons: With Verdugo, aka Uriarte, to Salazar.
• Composite Character: She's a combination of the black-robed Verdugo and U3.
• Creepy Centipedes: Her parasite tail continues to attack Ada after she seemingly kills Pesanta during their third and final encounter, dragging its limp main body around and moving around like a giant centipede.
• Cute Monster Girl: A very pointed aversion - she doesn't even have a female build anymore, and even before turning into U-III she's a horrifying bug-faced scorpion monster who is not visually different from Uriarte.
• Dark Action Girl: Is just as lethal, if not more so due to her One-Winged Angel form of U-III, than her male counterpart, Uriarte.
• Deadlier Than The Male: Pesanta is overall shown to be a much more threatening creature compared to her male counterpart Uriarte as she’s shown to be able to infect others with the Plagas parasite, conjure up illusions of herself that can directly harm her victims, and can transform into a giant centipede like monster whose lower half can survive without the top half.
• Designated Girl Fight: A rather unusual take on this trope, Pesanta, formerly a human handmaid who is now a heavily mutated monster, strictly faces off against Ada Wong multiple times.
• Dies Differently In The Adaptation: In the original, the black-robed Verdugo was absorbed into Salazar's transformation, and U3 was killed by Leon. Pesanta is instead put down by Ada.
• Flunky Boss: During the first two fights with her, Pesanta uses the parasite inside of Ada to make her hallucinate smoky doppelgangers of herself that are still able to inflict damage on her. She spawns dozens of them during the first encounter, but most of them will vanish after only a single hit, while it spawns only two in the second, which will persist even when shot. The second phase of the last encounter also has her summon Novistadors to attack halfway through.
• Gender Flip: Played with, as Pesanta is given an identifiable (from lore) gender to begin with in the remake, along with her own name.
• Glass Cannon: Pesanta has a far broader toolkit than Uriarte, even being able to infect targets with parasites remotely, but one area where she falls short is in defense. The Verdugo fought in the base game is the most resilient enemy in the game, with an armored body that bullets bounce off of and even being able to withstand a rocket launcher provided it's not frozen with liquid nitrogen first. Pesanta's body is far less resilient, with shots to the body resulting in blood splatters rather than sparks and Ada not needing to freeze her to make the fight easier.
• Glowing Eyes of Doom: Like the Verdugo, she has glowing red eyes that can be seen under her hood. The doppelgangers in the first two fights lack this trait, which helps to identify which is the real one.
• The Heavy: Of the Separate Ways DLC. With the exception of one encounter with Mendéz and Saddler, Ada never really interacts with the inner circle of Los Iluminados, spending two thirds of the DLC being hunted by Pesanta and trying to remove the parasite the U-III infected her with early on.
• Implacable Man: She pursues Ada through the DLC, and though she manages to drive it off or evade her, she keeps coming back until she puts her down for good.
• Meaningful Name: Pesanta is the name of a creature from Catalan folklore; a kind of giant, monstrous dog that gives people nightmares. This reflects both her Implacable Man nature, even being openly compared to a hunting dog, as well as her ability to induce hallucinations in those it implants with her parasites.
• Me's a Crowd: In her first two fights, courtesy of her parasite-induced hallucinations.
• Mythology Gag: Her ability to infect her victim's with hallucinations and cast the areas they're in with blue balefire, are nods to Resident Evil 4's cancelled "Hook Man" iteration.
• Named by the Adaptation: Prior to the remake's Separate Ways DLC, fans just called her "the other Verdugo" or "U-3".
• My Greatest Failure: Shortly before her infection with Las Plagas, the housekeeper lamented her failure to fulfill the late Lord Diego's last wish to keep Ramón from the path of wickedness, making it easy for Saddler to manipulate him into unsealing the parasites the Salazar family had protected the world from for generations. Her continued servitude to Ramón is partly out of loyalty to the family and partly out of penance to her former master.
• Nested Mouths: Her tail of all things has two sets of jaws.
• Ninja Maid: A rather horrific one, but Pesanta is Salazar's housekeeper, and she fights using ninja-esque dexterity and illusions.
• No Ontological Inertia: The parasites that she implants into her victims cannot survive without her. Almost as soon as Ada kills it, she vomits up the parasite.
• Painful Transformation: Pesanta's transition into her classic U3 look is without issue, but the housekeeper becoming Pesanta in the first place is described as having been excrutiatingly painful. Isidro admits in a note that her screams of torment during his experiments made his hair stand on end, noting that she will probably break completely if he can't complete the transformation soon.
• Recurring Boss: Ada fights Pesanta three times throughout the DLC, once at the very beginning, once at the end of the second chapter and then their final encounter in the fifth chapter.
• Samus Is a Girl: Her mutation has robbed her of any clear sexual dimorphism, but her human form was Salazar's maid.
• The Smurfette Principle: The only female (if she can even be called that anymore) high-ranking Ganado.
• Spontaneous Weapon Creation: Pesanta can form an organic spear out of her biomass, as well as grenades that implant her parasitic cells into those they touch.
• Technicolor Fire: The hallucinatory flames that keep Ada from leaving her arena during the first two encounters with it are a pale blue.
• Undying Loyalty: Even before she had her free will stripped away by Las Plagas, the housekeeper was decidedly loyal to the Salazar family, having been raised and served under Ramón's predecessor Diego Salazar. Even with the knowledge that Ramón's cruelty and association with Saddler will lead to the end of the Salazar line, she swore that she would watch over him until the very end.
• Was Once a Man: She used to be the Salazar family's housekeeper.
• Your Mind Makes It Real: Despite being hallucinatory, the duplicates that accompany her in her first two boss fights are still fully capable of killing Ada.

U3 / "It"

An experimental B.O.W Saddler keeps as a pet. It is a horrifying chimera of Plaga, human, insect, and reptilian DNA fused imperfectly to create a twisted abomination.

---

• Adapted Out: U3 is one of the only monsters from the original Resident Evil 4 that isn't present in the remake. It eventually makes an apprearance in the Separate Ways DLC in the form of Pesanta. See the folder above for tropes regarding that character.
• Body Horror: U3 has a tentacle in lieu of an arm, an oversized lolling tongue, a lower jaw that's crudely broken into mandibles, and has mutated into a vaguely tauric body configuration composed of what seems like three or more human bodies.
• Body of Bodies: As mentioned above, it's implied that the U3 is composed of more bodies melded together in a horrific centaur abomination. Apparently, the snake-like body can survive the death of the humanoid torso.
• Combat Tentacles: Its left arm is a long, tentacular appendage that it uses like a whip against threats.
• Disney Villain Death: Subverted. At first you try to get rid of it by dropping the container he's in down a seemingly bottomless shaft... only for the U3 to climb back up to resume the chase.
• Giant Space Flea from Nowhere: U3 shows up in the original Resident Evil 4 after Leon finds the tracker he placed on Ashley with almost nothing foreshadowing its existence in files or dialogue with the exception of the call between Leon and Saddler where he said he would introduce Leon to "It".
• Implacable Man: As soon as he appears, he won't stop coming after Leon, even when his humanoid torso is killed, leaving the massive worm-like appendage in charge.
• Overly-Long Tongue: The humanoid torso features an oversized tongue lolling out of the mouth.
• Power Pincers: The worm thing has massive spiked mandibles that the U3 can use to One-Hit Kill Leon by biting him in half.

Martinico

An experimental B.O.W. kept on the Island in the remake version of Separate Ways. Highly durable, its only method of containment—and extermination—is a hallway filled with high-powered lasers.

---

• Adaptational Explanation: The explanation in question - it's the reason the laser hallway exists in the remake, as it is the only way to contain them.
• Canon Foreigner: Martinico did not exist in the original 2005 game, being an original creation for the remake's Separate Ways DLC.
• Cutscene Boss: Shortly after its introduction and a brief chase scene, Martinico is killed off in a series of QTEs in the laser hallway.
• Deadly Upgrade: According to the research notes, Martinico started off as an ordinary drone Plaga-infectee which got exposed to "The Amber" as an experiment by an enthusiastic researcher in his research. The exposure ended up violently mutating the Plaga in Martinico, until he became a hideous unstoppable borderline-immortal juggernaut who nobody could control anymore and had to be sealed away for everyone's safety.
• Escape Sequence: It's Nigh-Invulnerable to conventional weapons, forcing Ada to flee from it during every encounter until it gets cut into pieces by the laser hallway.
• Meaningful Name: Martinico is the name of a type of goblin found in Spanish regional folklore.
• Nigh-Invulnerable: He'll shrug off anything Ada throws at him. Only the laser hallway can put him down.

Popokarimu

Popokarimu

A genetically engineered hybrid of a giant bat and a Plaga strain. Created by TRICELL as their newest B.O.W to sell off, Ricardo Irving instead decides to sic it on Chris and Sheva.

---

• Advancing Boss of Doom: If you attempt to flee the second Popokarimu encounter, it will chase you up the stairs, and you need to Press X to Not Die.
• Beware My Stinger Tail: It can bodyslam, sweep, pincer-bite, and launch Super Spit from its tail.
• Body Horror: It resembles a monstrous, malformed bat with a distorted, oversized lower jaw and a twisted, near-human countenance, with its legs trailing off into an armored beetle grub-like lower body.

LOOK at this abomination.

• Mix-and-Match Critters: Half bat, half insect, looking like a giant, deformed bat with a grub replacing its lower body.
• Not Quite Dead: After seemingly being put down by Chris and Sheva, it returns once more later during their adventures.
• Super Spit: It can spray gouts of Hollywood Acid from its tail.

U-8

Ultimate 8

A TRICELL B.O.W created through splicing together genes of shelled arthropods and infecting the hybrid with a Plaga strain. A big hit on the black market, it's primarily valued for its intelligence and usefulness in guarding high-profile facilities.

---

• Attack of the 50-Foot Whatever: The creature is enormous, roughly half the size of a Kaiju.
• Awesome, but Impractical: Despite its success as a guard dog, TRICELL admittedly never quite got the creature right. Its overwhelming size and lack of speed made it completely useless for militaristic purposes; militants would just bombard the monster's legs with explosives from a distance with it being unable to accomplish anything. As a result, it was mostly relegated to guarding high-profile facilities and bases. An attempt was made to balance its defensive capabilities with offense but that too fell flat.
• Feed It a Bomb: When stunned, the player can throw a grenade into the creature's mouth provided they have one in their inventory.
• Mook Maker: U8 has a distinct ability to spawn mosquito-like creatures to swarm its enemies.
• Stone Wall: Its entire purpose. The shelling of the U-8 is nigh-impenetrable but its offensive abilities outside of overwhelming a human in one-on-one combat are said to be miserable. Implied to have been taken up to eleven with the U-8 Prime, an unseen derivative said to further enhance its already impressive defense.

Resident Evil: Code Veronica

Gulp Worm

An enormous mutated annelid that appeared on the prison island after the T-Virus leak.

---

• Giant Space Flea from Nowhere: The Gulp Worm literally shows up out of nowhere after Claire leaves the military training facility for the first time. There's no files or anything that even hints at where it came from.
• Noisy Nature: When it surfaces, it likes to roar like a monster.
• Skippable Boss: Claire literally never has to fight the creature, as it moves so slowly that she can easily run through the area where it patrols and never get hit. Chris can do likewise, and unless Claire did the miniquest where she got Rodrigo the Haemostatic Medicine, there's no reason for him to fight it either — if she did, then Chris has an incentive to do so, as killing it will give him the lighter and enable him to reach some valuable goods, including a pair of sub-machine guns.
• Underground Monkey: It's basically a retread of the Gravedigger from Resident Evil 3: Nemesis.

Albinoids

An experiment in creating amphibious B.O.Ws by applying the T-Virus to salamanders. Albinoids possess the ability to disperse deadly electrical voltage and are sizable, growing to a size of approximately 7 feet long in a mere 10 hours.

---

• Body Horror: They're so mutated that it's almost impossible to recognize their salamander ancestry.
• Psycho Electro: They attack by emitting bursts of electricity from their bodies.
• Ramming Always Works: The adult albinoid attacks by charging into its prey with bone-crushing force.
• Skippable Boss: Chris encounters an adult albinoid when he reaches Rockfort, swimming around in a pool. He can kill it, and it's quite easy to do because it can't leave the pool, but he can also save the ammo and just tank the damage to be had from jumping into the pool, retrieving the key item, and then leaving again.

Uroboros

In general

Depicted: the unnamed boss referred to as "test subject," the first Uroboros monster encountered.

^{Uroboros Mkonos}

^{Uroboros Aheri}

Appearances: 5, Revelations 2

Uroboros (Uroboros Virus) is a Progenitor derived RNA virus and WMD created by Albert Wesker. It is at the center of a self-titled eugenics conspiracy to wipe out most of the human race and "elevate" what remains into a superior species. In contrast to Excella Gionne's admitted desire to not want them degraded to B.O.W.s, samples obtained by Alex Wesker were later engineered to create such for the black market.

---

• And I Must Scream: If one looks closely, one can find the faces of the incompatible human hosts somewhere on the mass of tentacles; their expression is contorted into one of sheer agony, implying that like G-Birkin, they're aware of what's going on but are powerless to do anything.
• Attack of the 50-Foot Whatever: The size of Uroboros monsters from the unrefined strain varies on how much body mass they've taken in. One human body will result in a creature slightly larger than the average person; a mound of corpses, as seen with Uroboros Aheri, will result in a Kaiju.
• Body Horror: While Albert Wesker wanted to ascend humanity to the next evolution level, what Uroboros actually does, regardless of genetic compatibility, is degrade them into horrifying abominations. The original strain of Uroboros monsters derived from living humans can largely be described as black masses of tentacles that barely retain the human visage that was once there. The B.O.W. derivatives aren't even derived from living humans or zombies, but random body parts stitched together.
• Combat Tentacles: Uroboros monsters/mutants derived from the unmodified strain are distinguished by the black biomass that makes up their being, which visually resembles writhing tentacles.
• Made of Iron: Uroboros monsters typically possess a Healing Factor that renders them nigh-invulnerable to conventional weaponry. While they can be killed by just being shot at, their sheer resilience encourages the player to focus on their cores at all costs.
• Mook Maker: The original strain of Uroboros monsters can create small-sized tentacle mooks to harass the player.
• Only the Chosen May Wield: The virus itself is extremely picky with who can use it to its full potential, with most of its hosts devolving into undulating masses of black tentacles. Even Albert Wesker isn't compatible with it despite designing it, with Word of God stating that if Chris and Sheva didn't kill him, the virus would've consumed him. The only person shown to be fully compatible with the virus is Neil Fisher, who transforms into a hulking mutant with increased muscle mass, with Alex being a debatable example as she was already mutated by the T-Phobos virus.

Reaper

Common African household cockroaches accidentally exposed to Uroboros, the Reapers demonstrate that virus' extreme potential for deadly mutation, having transformed into killing machines.

---

• Blade Below the Shoulder: Of the "blade for a hand" variety. Each arm is a serrated scythe blade.
• Creepy Cockroach: Cockroaches mutated into larger-than-human bipedal monsters. You can scream now.
• Elite Mooks: Encounters with Reapers see them deviously placed within waves of standard Majini to complicate the situation.
• From Nobody to Nightmare: These things used to be regular household roaches. After their infection, the Reapers proceeded to butcher multiple squads of armed Majini sent to capture them, becoming extremely effective B.O.Ws.
• Healing Factor: They can regenerate their head and arms, which is why you gotta aim for their organ sacks.
• Meaningful Name: They were given their nickname by Tricell after the security teams that were sent in to deal with them were repeatedly butchered by the creatures. It also helps that their claws look like scythes.
• Multi-Armed and Dangerous: They have four arms, all of them giant reaping sickle claws.
• Pupating Peril: In some of the levels they’re encountered, huge cocoons containing metamorphosing Reapers can be seen hanging from the ceiling. Some of them will also hatch when disturbed, unleashing their homicidal contents upon the player.

B.O.W.s

AKA: Revenant, Slinger, Splasher, Durga

A Revenant and Splasher

^Slinger

^Durga

Marketable Uroboros monsters. The ones seen on Sein Island are made up of the corpses of torture victims of T-Phobos experiments, thus explaining their particularly horrifying appearances.

---

• Appendage Assimilation: Durgas are the more traditional Uroboros monsters, having assimilated multiple corpses together to become bizarre, walking tree-like horrors.
• Blade Below the Shoulder: Revenants often sport rusty, jagged blades in lieu of arms, or even as peg legs.
• Body Horror: Even relative to its viral strain, these things are some of the most visually unnatural and terrifying monsters in the franchise; they're all hobbled mishmashes of tortured human corpses made sentient by an already unstable virus, but the body horror varies from creature to creature.
  • The Revenant and Splasher are the most visually humanoid monsters, which does not help. From top to bottom, we see how badly the people that make them were tortured by Alex: their flesh has discolored gray from necrosis and abuse, and their arms have been either amputated with crude house tools to replace them or give way to a mutated appendage; another head is also fused onto the base head, with faces contorted in expressions of pure agony. Additionally, although they are not living creatures per se, their pupils have not dissipated unlike typical zombies, which coupled with their fixed jawlines gives the impression they are aware of their state.
  • The Slinger is essentially a pair of human legs held up by a mass of human flesh with no head. As if that weren't bad enough, closer inspection of the upper body illustrates its made up of decapitated torsos, evident by the collars where they would be. When engaged in combat, the Uroboros bulb will emerge from the central piston.
  • However, the Durga is the worst by far. Visually resembling the Slinger with its legs and top-heavy build, it is distinguished by its upper body being comprised of hands upon hands unnaturally fused on a mass of rotting flesh. Multiple human faces are also seen sewn all over where a head would be, extending to its back as well.
  • In addition, none of these monsters need their head or central limbs to function as long as their cores are not destroyed. A Revenant for instance could be decapitated and dismembered without end and will just regenerate new and often inappropriate limbs on top of what was lost; they could wind up being headless multi-armed/legged monstrosities not dissimilar visually to the Mannequins of Silent Hill 2.
• Combat Tentacles: To make up for their immobility, the Durga will manifest traditional Uroboros tentacles to reach out to the player at a certain range.
• Hell Is That Noise: When provoked into combat, Revenants will let a horrifically distorted human bellow despite the fact they should logically be incapable of making such a noise.
• Marionette Motion: The Revenants and Splashers shamble with an uncanny, puppet-like gait complete with twitching.
• Mighty Glacier: The Durga is incredibly slow but it can reach out with damaging tendrils in addition to its main attack upclose being a One-Hit Kill.
• Nightmare Face: Revenants and Splashers have visible human faces that look like they're screaming in agony.
• Support Party Member: The Slinger is always accompanied by its brethren and will always try to stay away from the player and launch its interface-screwing bile from a distance. It will launch a massively damaging melee attack up close, however.

Resident Evil 0

Leeches

Above: Marcus' leeches; Below: normal t-Virus leeches

Appearances: 0, Outbreak, Umbrella Chronicles

Leeches infected with the t-Virus. The leeches experimented on by Dr. James Marcus are identifiable by their maw of teeth and eye on their back; these leeches were from which the t-Virus was derived after Progenitor exposure. Ordinary leeches with next to no irregular mutations were later seen in the Raccoon City outbreak.

---

• Big Creepy-Crawlies: They're overgrown leeches that can, among other things, easily kill adult humans. It doesn't get much worse than that.
• Hive Mind: Most of them are controlled by a Queen, as we see with the one that inherited Marcus' intelligence and memories and the Giant Leech in Outbreak.
• More Teeth than the Osmond Family: Marcus' leeches have maws of sharp fangs, illustrating how much more dangerous they are than the average critter.
• Small Role, Big Impact: Leeches are from where the t-Virus was created. Before that, the Progenitor Virus was described as a nearly useless pathogen on its own. There's also the fact that one of these things gained sentience and would kickstart most of the events in the series.

Mimicry Marcus

Appearances: 0, Umbrella Chronicles

Though Marcus' general leeches are incapable of maintaining (relatively) perfect sentience like the Queen Leech, they can combine to crudely imitate a human form and become far more dangerous in the process.

Despite often being referred to as the "Leech Man," this monster should not be mistaken for being related with the one from Outbreak.

---

• Acid Attack: It constantly drips and spews acidic bile in everything it does.
• Body Horror: It's a perverse imitation of a human form made up of zombie leeches. It can barely even be said to look human at all, instead looking more like the Lying Figure from Silent Hill 2.
• Lightning Bruiser: Don't let its lean appearance fool you, this monster is one of the toughest in their appearances: They're insanely fast and can use their long arms to instantly close the gap in corridors, soak insane amounts of damage and bring colossal pain in all their attacks.
• Scare Chord: These monsters don't appear too often and most of their appearances are scripted. As a result, when they do show, they're accompanied by a now-infamous theme of this trope.
• The Worm That Walks: It's a mass of zombie leeches aping the form of their creator. If one dies without burning to death, it'll break apart and unleash several regular leeches to attack the player.

Plague Crawler

Appearances: 0, Umbrella Chronicles, Darkside Chronicles

Experimental B.O.W.s that Dr. Marcus created through insect gene splicing and the t-Virus. Due to being too unintelligent and uncontrollable, they were considered failures.

---

• Awesome, but Impractical: Marcus saw them as this for military warfare, which is accurate. Javier Hidalgo, however, found a use for them ala Cartel brutality.
• Big Creepy-Crawlies: They're giant zombie mantis-like cockroach hybrids.
• Fed to the Beast: The drug lord Javier Hidalgo either obtained blueprints on these monsters or they ended up on the black market. His purpose for them was to make an example of dissenters by feeding them to the beasts.
• Hell Is That Noise: Their presence is made known before they even show on the screen with their monstrous hissing.

Eliminator

Appearances: 0, Umbrella Chronicles

Primate-based B.O.W.s. The Eliminators were deemed complete failures for their heightened aggression and loss of intelligence. They were left to rot away in cells until Billy and Rebecca toured the Training Facility, at which point they were released.

---

• Flawed Prototype: While they were capable of following basic orders, their increased aggression and lowered intelligence made them useless as a functional bioweapon. This ultimately led to Umbrella scrapping efforts to weaponize them in favour of human tests.
• Lightning Bruiser: They're very nimble and hit hard.
• Maniac Monkeys: They're t-Virus infected monkeys, and about as rabid as they come.
• Worf Had the Flu: Despite how tough they are in-game, the Eliminators in 0 are explicitly weakened by severe starvation and neglect.

Lurker

Appearances: 0, Darkside Chronicles

The last of Marcus' failed animal B.O.W.s before human experimentation began. A toad gigantified by the t-Virus with no changes besides heightened aggression.

---

• Glass Cannon: To a ridiculous degree. While it won't kill them, merely shooting at one of them will cause them to flee and never return. However, their only attack is a frustrating One-Hit Kill if the player isn't quick enough.

Stinger

Appearances: 0, Umbrella Chronicles

A scorpion-like B.O.W. Umbrella was transporting over the Ecliptic Express.

---

• Big Creepy-Crawlies: Giant zombie scorpion.
• Giant Space Flea from Nowhere: There is nothing on this creature's origins or purpose. It being a B.O.W is even only inferred.
• Shielded Core Boss: Its face is its only weak point. It will raise its pincers to defend itself but inevitably lower them to attack.

Centurion

Appearances: 0, Umbrella Chronicles

A centipede in the Umbrella Training Facility that was accidentally exposed to the t-Virus.

---

• "Get Back Here!" Boss: It spends the entire fight running around with Rebecca as its hostage, only hurting Billy if he walks in its path. The player has a set time to kill it or it will snap Rebecca's spine.
• Giant Space Flea from Nowhere: Like most of 0's bosses, nothing is officially known of why this thing exists. It just shows up for a boss fight.

Giant Bat

Appearances: 0, Umbrella Chronicles

An oversized zombified bat infected with the t-Virus.

---

• Bat Out of Hell: A gigantic zombified bat.
• Giant Space Flea from Nowhere: The last of three of 0's inexplicable animal-based monsters that just show up for a fight with no explanation or backstory.
• Flunky Boss: It's swarmed by little zombie bats in its fight.

Queen Leech

^{Click here to see its second form}

Appearances: 0, Umbrella Chronicles

The true form of the Mysterious Man posing as Marcus. It was a dominant leech Marcus was experimenting on before abruptly being gunned down by U.S.S. troops, subsequently being thrown away with him into the sewers. The leech merged with Marcus' corpse and, within a decade, resurrected with his consciousness. Seeking revenge, it kickstarted the Arklay disasters.

---

• Achilles' Heel: Its weakness to sunlight is what gives Rebecca and Billy the chance to survive.
• Back from the Dead: Subverted. The Queen Leech thinks it is Marcus reborn, but it actually just absorbed his memories from his corpse and has the ability to take his form.
• Big Bad: Of 0. It's responsible for causing the Arklay disasters as a form of revenge for Marcus's murder by U.S.S. troops, and has been impersonating him throughout the game.
• Body Horror: Its true form is a humanoid monster comprised of thousands of leeches. It loses its human shape completely upon mutating a second time.
• Combat Tentacles: In its first form, it primarily attacks with its elongated limbs.
• Final Boss: Naturally, it is the final enemy encountered in 0.
• The Heavy: For 0, overlapping with his status as Big Bad.
• King Mook: Its first form is basically an ultra-tough Mimicry Marcus, only it doesn't bite.
• Omnicidal Maniac: Planned to destroy the entire world after it was done with Umbrella.
• Puzzle Boss: Its second fight involves trying to distract it away from either Billy/Rebecca opening the ceiling hatch to expose it to the sun. It can't be killed otherwise but it's necessary to harm it in order to slow it down.
• Weakened by the Light: In the dark, the Queen Leech is implacable. After being sufficiently exposed to sunlight, it is neutralized in a single shot.
• The Worm That Walks: Its human form is a mass of leeches able to gain sentience through the Queen absorbing Marcus' consciousness. The Mimicry Marcus, by comparison, is a perverse imitation of this without the intelligence to make it work.
• Villainous Legacy: Long after the Queen's death, its wish to bring down Umbrella eventually comes true in 2003.

Resident Evil

Chimera

Appearances: Resident Evil (and remake), Umbrella Chronicles, Marhawa Desire

The last of the deliberate B.O.W experiments conducted by the Arklay team was the Chimera, a repulsive mixture of human and fly DNA made possible through the mutagenic effects of the t-Virus. Whilst strong, quick, agile, and aggressive, it was impossible to tame, relatively frail, and stupid, leading to it ultimately being shelved in favor of the Hunter line.

---

• Body Horror: Chimeras are a truly revolting mixture of human and fly traits.
• Facial Horror: The remake version of the Chimera has both human/insect hybrid features such as mandibles and fly-like hair, and looks as though it is constantly screaming in agony due to having a human upper jaw with no corresponding lower jaw.
• Glass Cannon: They're strong and fast, but fragile; one grenade round will kill them, as opposed to two for the Hunters.
• Half-Human Hybrid: Chimeras are the result of using the T-Virus to facilitate splicing invertebrate DNA into fertilized human embryos. The never-released-outside-Japan guidebook "Inside of Bio-Hazard" reveals that Umbrella kidnapped homeless women and used them as surrogates to bring the first Chimera to term, and then cloned the most successful versions.
• I'm Melting!: When killed, they sort of shrivel up and deflate.
• Insectoid Aliens: Chimeras are grotesquely humanoid insects like the Drain Deimos and Brain Suckers from 3.
• Wall Crawl: The Chimera can climb along walls and ceilings, which allows them to attack their victims from unexpected directions.

Neptune

AKA: FI-03

Appearances: Resident Evil (and remake), Umbrella Chronicles, Outbreak

One of the odder experiments the Arklay team attempted was FI-03, codenamed "Neptune"; t-Virus-infected great white sharks. Although successful in proving the t-Virus would work on marine organisms, the resultant giant sharks were of little practical use.

---

• Awesome, but Impractical: Sure, Neptune are giant zombie sharks, but since they can't be controlled, Umbrella could not find a use for said giant zombie sharks. The only gain the company made with Neptune was proving that the t-Virus could infect marine organisms. And then there’s the problem of transporting said sharks if they did figure out a use for them.
• Logical Weakness: The Neptunes may be zombie sharks, but they are still sharks, so they are rendered harmless once you drain the water from the laboratories they inhabit, which will outright kill some of them in both the original and the REmake.
• Threatening Shark: They are great whites grown to the scale of the shark from Jaws.

Yawn

Appearances: Resident Evil (and remake), Umbrella Chronicles

Another animal experiment that the Arklay team tried was exposing an adder to the t-Virus. This creature would grow into a massive, man-eating giant, which the team dubbed "Yawn". Secondary exposure led to other adders in the nearby forest being exposed, causing them to become more aggressive and virulently venomous.

---

• Disc-One Final Boss: Yawn's death precisely marks the end of the first half of the original game and its remake.
• Hero Killer: It always kills Richard Aiken sans Chris' scenario in the remake, where it's possible to save him from that fate only for him to be killed by Neptune later.
• Kick The Son Of A Bitch: Yawn is why most of the depraved Arklay research staff is dead, viral outbreak notwithstanding. When the outbreak hit, it went out of control and ate most of the researchers and made the mansion its home.
• Meaningful Name: Was nicknamed "Yawn" in reference to the way its mouth opens before attacking, which resembled a yawn
• Optional Boss: In the remake, scaring it off in the first encounter isn't necessary, as the player can just run put the room after taking the Death Mask.
• Poisonous Person: It has an extremely potent venom. Letting it bite you in the first encounters will result in a Fetch Quest to get cured of its poison.
• Recurring Boss: It's fought twice in the first game and Umbrella Chronicles, making it the most recurring boss of its game and timeline.
• Snakes Are Sinister: It's a giant zombie snake, and it is terrifying.

Plant 42

Appearances: Resident Evil (and remake), Umbrella Chronicles

Contaminated water from the flooding of the Aqua Rings lab exposed a plant at "Point 42" of the lab's map to the t-Virus, causing it to grow into a massive, predatory mutant.

---

• Acid Attack: It's capable of spewing copious amounts of acid.
• Combat Tentacles: They're vines, but have the same effect. The vines are even called tentacles in the official guidebook.
• Logical Weakness: Plant 42 can be killed with fire or by spraying herbicide over its roots.
• Man-Eating Plant: Its files state it racked up quite a body count before the entire Arklay facility was lost.
• Skippable Boss: It can simply be killed with herbicide without actually fighting it.
• Villainous Legacy: Despite being a completely accidental failure that was responsible for the destruction of much of the Arklay research staff, Umbrella took an interest and used salvaged data to produce Plant 43, a fairly successful humanoid B.O.W derived from a plant like Plant 42. A derivative from this called Ivy +YX made its way into the bioterror black market as well.
• Weak to Fire: If Jill has the grenade launcher, three flame rounds will destroy it.

Wasp

Appearances: Resident Evil (and remake), Outbreak

A nest of wasps in one of the cabins on the mansion's grounds were exposed to the t-Virus and grew much larger. These creatures were also found in various places during the Raccoon City outbreak.

---

• Big Creepy-Crawlies: Japanese giant hornets are probably the most feared insects in real life. Take that and zombify them, increasing their size in the process.
• Lethal Joke Character: They aren't all that threatening in the games proper, but there exists a special wasp in the remake that will emerge when the player solves the Bee Puzzle; this significantly larger wasp even compared to its relatives has 1200 HP and deals 200 points of damage per hit.^note for reference, T-002 in its final encounter has 2400 HP to Chris and Jill's 1400 and 960. Needless to say, the player will want to immediately get out of the room and never come back than remotely try to fight it.

Resident Evil 2

Plant 43

AKA: Ivy, Ivy Zombies

^{Ivy +YX}

^{Plant 43 (Resident Evil 2 2019)}

^{Ivy Zombie}

Appearances: 2 (and 2019 remake), Umbrella Chronicles, Darkside Chronicles

An experiment in plant-based B.O.Ws, whilst voracious and resilient, the Plant 43s were sluggish and mindless creatures. Believed to have been destroyed with Raccoon City, the data on these monsters was recovered and a stronger derivative known as Ivy +YX ended up on the bioweapon black market.

In the 2019 remake of Resident Evil 2, Plant 43 refers to a botanical abomination not dissimilar to its predecessor that was being experimented on in NEST. With the t-Virus outbreak and rampaging G-Birkin on the rise, Plant 43 subsequently went out of control and infested NEST with vines. From these vines, it would absorb the corpses and zombies scattered about and reanimate them as monsters dubbed "Ivy Zombies".

---

• Combat Tentacles: The original Ivy's primary attack method is to club things to death with its long vines.
• Decomposite Character: Plant 43 was the codename of the Ivies themselves in the original. The remake changes this by making Plant 43 an actual, separate entity not unlike Plant 42 of the first game, while the Ivies are now human corpses colonized by its seedlings.
• Faking the Dead: In the 2019 remake, unless it has been reduced to a charred husk from fire-based weapons, an Ivy will eventually get up after regrowing its weak points.
• Fire Keeps It Dead: In the remake, unless an Ivy’s been burned, it will eventually regenerate and resume its attack.
• Hell Is That Noise: As if to make them inhumanly creepier, Ivy Zombies in the 2 remake will constantly croak in a way that suspiciously sounds similar to Kayako Saeki's infamous death rattle.
• Informed Attribute: Ivy +YX models are supposed to be faster and stronger than the originals, but this never really comes across in The Darkside Chronicles.
• Made of Iron: An Ivy can take a lot of firepower before it goes down. In the 2019 game, they'll never die without being burned.
• Mighty Glacier: Ivies may be tough, but they move extremely slowly. In the remake, though, they're more like a Lightning Bruiser: they move a lot faster, they're still tough and can only attack via One-Hit Kill.
• Man-Eating Plant: They're mutated plants engineered to be mobile and carnivorous. Or, in the 2019 remake, they're human corpses infested by mutated carnivorous plants.
• Mix-and-Match Critters: An Ivy +YX looks like a tropical version of the standard Ivy with human legs.
• More Teeth than the Osmond Family: The 2019 Ivy has a head that splits in half vertically to reveal a mouth filled with jagged fangs, which they can then use to bite off the face of their hapless victims, resulting in a One-Hit Kill. These jaws are strong enough to bite through even reinforced helmets and face masks, so even HUNK and GHOST aren't safe from this attack.
• Mook Maker: Downplayed, but the Ivies in the 2019 game are all progeny of Plant 43 and can be seen hanging from the ceiling, wrapped in vines as they complete their "gestation" in several parts of the East Wing.
• Nightmare Face: The Ivy Zombie's face can only be described as an eyeless human face with an expandable venus fly trap for a mouth.
• Personal Space Invader:
  • If a character gets too close to an Ivy, it will try to grab them so it can drool acidic nectar over their face.
  • The Ivy Zombie's only attack is to grab a character and then bite off their face.
• Poisonous Person: If the A-scenario character in Resident Evil 2 disperses the anti-B.O.W gas, the B-scenario character will face Ivies that have assimilated the gas into their system, causing their spit attacks to become poisonous.
• Parasite Zombie: The Ivies in the remake of 2 are the overgrown corpses of former research staff infested and controlled by the seedlings of the main plant.
• Super Spit: Ivies can spit acidic nectar over a short distance - well, we say "short", we mean "at a longer range than Leon's flamethrower".
• Turns Red: Mutant/Poison Ivies, the poisonous Ivies created by turning on the anti-B.O.W gas in A-scenario, can be distinguished by their crimson heads & bodies.
• You Don't Look Like You: An Ivy in the original RE2 looks vastly more plant-like than humanoid, consisting of a huge, forward-drooping flower-bud (kind of like Pyramidhead) atop a spindly caricature of a bipedal form, with bud-tipped vines for arms and flat feet clearly adapted from roots. In the 2019 remake, they are considerably more humanoid-looking, with an appearance more like a cross between Swamp Thing and the plant-infested "Green Zombies" from Resident Evil: Outbreak. Their lore has also changed from being a B.O.W in the original game to an accidental mutation in the 2019 remake, being human corpses colonized with by seedlings of Plant 43.

G-Spawn

A G-Spawn as it appears in Resident Evil 2 (2019)

^{Concept art for original appearance}

^{Outbreak appearance}

^{Click to see the G-Larvae}

^{Click to see the G-Zombie (Darkside Chronicles)}

Appearances: 2 (and 2019 remake), Outbreak, Darkside Chronicles

"G" is the name given to any mutant created through infection of the G-Virus, although these monsters are referred to as "G-Spawn", a monster that resulted from G-Birkin impregnating unsuitable hosts. Larvae would burst open from said hosts and quickly grow into the G-Spawn, similarly seeking other human hosts to impregnate.

---

• Body Horror: The G-Spawn is a twisted abomination, even if its precise appearance varies from depiction to depiction.
  • The original G-Spawn looks vaguely like a deformed, tumorous human embryo grown to the size of a bear. This appearance is "polished up" in The Darkside Chronicles'.
  • The 2019 version is clearly based on the original, but manages to be even more disgusting - its right arm is much more grotesquely bloated, and it has a massive hump-like growth sticking out of its back.
  • The G-Spawn that sprouts from Monica looks almost human... except for its tumorous tail, its Eyeless Face, oversized right arm, and the enormous hump of distended tumors sprouting from its back.
• Chest Burster: In the original game, the G-Spawn is the result of Birkin trying to implant either Brian Irons (Claire A) or Ben Bertolucci (Leon A); the resultant creature parasitizes them, and then violently tears its way out of their body. In Outbreak, a G-Spawn is created when Monica's attempts to smuggle a G-Larva out of Raccoon City to sell it for profit, a goal for which she kills multiple people, ends up thwarted when she accidentally releases the G-Larva and is subsequently impregnated by it. In the 2019 version, Birkin has infected multiple zombies, resulting in multiple G-Spawn.
• Degraded Boss: In the original game, G-Spawn is a Mini-Boss in the A-scenario. In the 2019 games, you'll encounter multiple versions of them in the Raccoon City sewers, where they're closer in durability to Elite Mooks.
• Dumb Muscle: All versions of the G-Spawn have no real brains, and just mindlessly attacks whatever they encounter.
• Eyes Do Not Belong There: The 2019 version has the iconic G-Host eye on its left shoulder, which is initially covered in a fleshy mass. The Monica G-Spawn has at least one giant eye in the middle of its spinal mass of tumors.
• It Can Think: In the remake, they seem to talk and sing to themselves when left idle. It holds some disturbing implications to say the least.
• Mini-Boss: In Resident Evil 2, it's basically a weaker version of First Form Infected Birkin, and is fought roughly midway through the first scenario, the last barrier before your character reaches the sewers. Subverted in Outbreak, where it's a full-fledged boss fight, being the last enemy to overcome in the scenario "Below Freezing Point".
• Mook Maker: G-Spawns all have the ability to create squamous, spider-like "G-Larvae" as expendable attack drones.
• Nested Mouths: The 2019 G-Spawn has the ability to extrude a long, hideous, tentacle-like "inner mouth", which it mostly does when spewing out G-Larvae.
• Zombie Puke Attack: G-Spawns can produce gouts of toxic fluid as an attack mechanism. The G-Spawn faced in 2 rarely does this, but the one faced in Outbreak uses it more frequently. This is retooled as a grapple attack in the Remake of 2

Alligator

Resident Evil 2 (2019)

^{Click to see Outbreak appearance}

Appearances: 2 (and 2019 remake), Survivor, Outbreak, Darkside Chronicles

A giant, t-Virus infected alligator. Two enormous and grotesque zombie-like gators were inexplicably found in Raccoon City and Sheena Island's sewers; more conventional-looking zoo attractions were found zombified in the Raccoon City zoo.

---

• Advancing Boss of Doom: In the remake, Leon must run away from the alligator while dodging to the left or right in order until it bites into a gas line where you must then shoot it.
• Demoted to Extra: In the original, it served as a boss fight in scenario A and possibly in B. In the remake, it only appears in Leon's campaign. While it was not a difficult boss, it could be more than the Cutscene Boss it was relegated to.
• Giant Space Flea from Nowhere: The one that come after Leon and Ark have no explanation for existing unless the audience wants to believe alligators occupy sewers of city complexes.
• Optional Boss: The gator found in Survivor is only encountered if the player spends too long in the sewers.

Giant Moth

Appearances: 2, Survivor, Outbreak, Darkside Chronicles

A failed B.O.W. that was set loose after NEST fell to ruination. Another one was inexplicably found on Sheens Island.

---

• Adapted Out: The giant moths were removed entirely from the Resident Evil 2 Remake like most of the insect enemies from the original.
• Big Creepy-Crawlies: A giant zombified moth with newfound cannibalistic tendencies.
• Poisonous Person: Their most potent means of offense is inflicting the poison status ailment.

Cockroaches

Appearances: 2 (and 2019 remake), Survivor, Code: Veronica, BIOHAZARD 4D-EXECUTER

Cockroaches that have been infected with the t-Virus. Along with rats, these disgusting vermin were one of the main instigators of spreading the virus that caused the Raccoon City outbreak. Cockroaches accidentally exposed to the Uroboros Virus would also accidentally create the much, much more fearsome Reaper monsters.

---

• Big Creepy-Crawlies: Giant zombie cockroaches.
• Demoted to Extra: In Code: Veronica, they are seen but aren't interactive enemies. Taken a significant step further in 2 (2019): though they appear in droves, they don't harm the player at all. In fact, they run at the sight of you if given the chance.

Resident Evil 3

Drain Deimos / Brain Suckers

^{Click to see Brain Suckers}

Appearances: 3 (and 2020 remake; Drain Deimos only)

Drain Deimos and Brain Suckers are scuttling, fluid-sucking insectoid horrors that Jill will encounter repeatedly throughout 3.

---

• *Drool* Hello: This is how a Drain Deimos is first introduced in the remake, leading to a fixed encounter where it implants its eggs in Jill.
• Face Full of Alien Wing-Wong: In the remake, the Drain Deimos that grapple Jill can implant parasitic larvae into her stomach, causing an Interface Screw that lasts until she takes a Green Herb.
• Fashionable Asymmetry: It's a little tricky to make out, given the sprites being used, but careful observer will notice that a Brain Sucker not only has two heads, but it has two right arms and one left arm, whereas the Drain Deimos has one head and four arms.
• Giant Space Flea from Nowhere: Almost literally, as they’re hulking, mutated fleas who have a propensity for spontaneously ambushing their prey from behind.
• Insectoid Aliens: Drain Deimos and Brain Suckers look like a repulsive blending of humanoid and insect traits.
• Multi-Armed and Dangerous: Drain Deimos have four arms with hook-like talons at their tips. The Brain Sucker only has three such arms; two on the right and one on the left.
• Multiple Head Case: It can be hard to make out with the graphics, but the Brain Sucker has two separate heads.
• Personal Space Invader: Drain Deimos, Brain Suckers and Sliding Worms like to grab Jill (or Carlos) and start sucking her fluids. For Sliding Worms, this is their only attack.
• Poisonous Person: Brain Suckers can potentially inflict the Poison status effect with their bite and spit attacks.
• Super Spit: Brain Suckers can launch toxic spittle at foes both in melee and from a moderate distance, although the ranged version of the attack does half as much damage according to the game's statistics.
• Underground Monkey: Not only is the Brain Sucker a recolored, two-headed, slightly tougher version of the Drain Deimos with a poisonous bite, but both creatures are based on the Chimera from Resident Evil, which has fueled the debate on whether or not they're B.O.W.s.
• Wall Crawl: Like the Chimera, Licker and Giant Spiders, Drain Deimos and Brain Suckers can climb on walls — however, in the original game, they can only move on walls, they can't get onto the roof and attack from above. This changed in the 2020 remake, where Drain Deimos can attack from the ceiling, just like Chimeras.

Gravedigger

Appearances: 3, Umbrella Chronicles

The Gravedigger is the biggest mutant in Raccoon City, an enormous infected annelid whose burrowing under the ground creates earthquakes and subsidence.

---

• Adapted Out: The Grave Digger was removed entirely from the Resident Evil 3 Remake, making Nemesis and its multiple forms and encounters the only boss fights in the game.
• Attack of the 50-Foot Whatever: The Gravedigger is enormous, at least the size of a bus.
• Giant Space Flea from Nowhere: The Gravedigger attacks with absolutely no forewarning, other than a possible route in which Jill falls into a now-open sewer and spots a shed skin before it attacks her for the first time. Likewise, there's no explanation as to where it comes from or what created it, and whilst there is a file in the park cabin which mentions a huge burrowing mutant, the author declares they don't even want to think about what might have spawned such a freak of nature.
• More Teeth than the Osmond Family: When the Gravedigger opens its maw, it's just ring after ring of fangs, with four huge fangs squaring up the head.

Resident Evil Outbreak

Leech Man

AKA: Leech Zombie

Appearances: Outbreak

A mass of t-Virus infected leeches that have taken control of a corpse. They're featured as the centerpiece of the "Hive" scenario in Outbreak File #1.

---

• And Then John Was a Zombie: If players are killed in the scenario by the creature, then their character will become another Leech Zombie.
• Attention Deficit... Ooh, Shiny!: Since it exists entirely to feed on blood, laying blood packs on the floor will immediately take its attention away from the player.
• Body Horror: It's hundreds of leeches congregating on a zombie.
• Implacable Man: This monster is an invincible stalker ala modern renditions of T-00 (Mr. X) until it's put in a furnace as part of a scripted fight.
• It Only Works Once: While players can kill the Leech Zombie that appears normally in the scenario using a furnace to prevent it from appearing again, it will only work on one of them. Because of this, it's best for players not to die in the scenario unless they want their character to become another Leech Zombie.
• The Worm That Walks: Actually a subversion unlike its predecessors, the (other) Queen Leech and Mimicry Marcus.

Giant Leech

Appearances: Outbreak

A monster living under the waterways of the Raccoon General Hospital. It's the queen of the leeches around the area.

---

• Mighty Glacier: It's strong but extremely slow, having no way to catch up to the player than flopping around. In fact, the player can always outrun it and it will give up pursuit until they return to it.
• Super Spit: Its most dangerous move is spitting a rain of acid, inflicting poison.

Hornbill

Appearances: Outbreak File #2

Hornbills from the Racoon Zoo that are infected with the t-Virus.

---

• Airborne Mooks: They essentially stand in for crows in the "wild things" scenario, so they're mostly the same except for being much more tenacious and persistent.
• Super-Persistent Predator: Unlike crows that usually mind their own business, Hornbills will NEVER leave you alone if they sight you. Pray you're playing Cindy, Jim, or Yoko so you can dodge their diving attack.

Lions

AKA: Max, Lioness

(Left) Max

Appearances: Outbreak File #2

Max was a popular zoo attraction and considered one of the stars of the Raccoon Zoo next to Oscar the Elephant. Several female lions were rented to the zoo as part of a breeding program, but all of them were zombified upon the city outbreak.

---

• King Mook: Max has the same abilities as the female lions, only he is far more durable.
• Lightning Bruiser: They're all very fast, durable, and hit hard.

Oscar the Elephant

AKA: Titan

Appearances: Outbreak File #2

The former star attraction of Raccoon Zoo. He now roams his playground as the greatest threat to all survivors and undead creatures.

---

• Bullfight Boss: It mainly attacks by charging toward the player at full speed.
• Damage-Sponge Boss: Contrary to his intimidating appearance, all of Oscar's attacks are not too difficult to dodge or play around. The problem is he takes so much damage it's unlikely the player will have enough ammunition to slay him in the first encounter.
• Mighty Glacier: Compared to Max's Lightning Bruiser, Oscar is definitely sluggish. While he can stampede as part of his charging attack routine, that's still pretty slow and can easily be sidestepped if the player isn't right next to him when he does it.
• Optional Boss: He is presented as this when free-roaming the zoo prior to his scripted fight; killing him there will save a survivor scripted to die to him and have Max the Lion fill in as the final boss.

Giga/Mega Bites

Appearances: Outbreak File #2

t-Virus mutated fleas that serve as one of the main enemies of the "underbelly" scenario. The average fleas are called Mega Bites, while one that has grown to an unbelievably colossal size is called Giga Bite.

---

• Attention Deficit... Ooh, Shiny!: Like the Leech Man, the small Mega Bites will immediately cease pursuit of the player if they lay a blood pack on the floor.
• Big Creepy-Crawlies: Giant zombie fleas.
• Body Horror: If a small Mega Bite is allowed to suck the player's blood, they will undergo an instantaneous metamorphosis into the giant one.
• Flunky Boss: The Giga Bite will periodically summon two Mega Bites to assist it.
• Giant Space Flea from Nowhere: Possibly the most literal example of this ever: they're huge monster fleas that show up halfway through the "underbelly" scenario with no foreshadowing or explanation.

Nyx

Appearances: Outbreak File #2

An experimental B.O.W. that U.S.S. defector Rodriguez planned to use to testify against Umbrella in court. Should the player fail to reach Rodriguez's helicopter in time, a scuffle will see Nyx escape its containment. whereupon it replaces the Tyrant R as Final Boss of the "end of the road" scenario.

---

• Body of Bodies: Dozens of human corpses and the Tyrant R are strapped onto this thing's fleshy mass.
• Combat Tentacles: The main form of offense it has is its tentacles.
• Damage-Sponge Boss: Nyx is borderline impossible to kill conventionally without attacking its rarely exposed heart, incentivizing players to use the detonator on the bomb-strapped Tyrant R it absorbed; doing so will instantly expose its core.
• Meaningful Name: Named after the Greek goddess of night.
• Mighty Glacier: It is very immobile but will use its long tentacles to make up for covering the distance.
• Optional Boss: Despite being the final boss that players can face in Outbreak File #2, the fight can be avoided entirely if you reach the helicopter in time before Rodriguez abandons you. If you don't make it however, the fight against Nyx becomes mandatory.

Resident Evil: Gun Survivor

Cleaners

A species of intelligent B.O.W.s used by Umbrella as a dedicated anti-biohazard task force. They're sent to Sheena Island to cover up the biohazard created by Commander Vincent.

---

• Cleanup Crew: The Cleaners act as one for Umbrella, being sent in to remove incriminating evidence, execute witnesses, and terminate stray B.O.W.s during outbreaks.
• Expendable Clone: The Cleaners are mass-produced by cloning at minimal cost to Umbrella. The company consequentially treats them as expendable soldiers, sending them on high-risk biohazard containment missions and executing them once the mission is complete.
• Faceless Goons: They're faceless Gas Mask Mooks serving under a human field commander.
• Fragile Speedster: According to Gun Survivor's guidebook, Cleaners were designed to be much faster-moving and agile than regular humans, but this came at the cost of making them much more fragile than even Zombies ^note For context, Gun Survivor Zombies HP values vary between 90 and 250 HP, while the main character has around 200 at base. Cleaners have no more than 20 HP at maximum.
• Gas Mask Mooks: They wear face-concealing gas masks with camera-like visors.
• It Can Think: They're intelligent enough to understand orders and operate firearms, a far cry from the usual mindlessness of B.O.W.s. However, they require a human field commander to give them their orders.
• Meaningful Name: Their job is to clean up after Umbrella's latest cock-ups, ensuring that any witnesses or stray B.O.W.s are terminated and any evidence incriminating the company removed.
• No Body Left Behind: Cleaners are designed to dissolve on death, befitting their role as expendable B.O.W.s charged with removing evidence that could incriminate Umbrella.

Resident Evil: Dead Aim

Pluto

One of the many failed B.O.W.s. that now roam the abandoned Atlantic Biosphere facility.

---

• Body Horror: It's already a tub of flabs, but when it takes enough damage, its head will disintegrate with its brain hanging out the stem for the remainder of the fight.
• Dumb Muscle: It's a single-minded brute with no cognitive ability to form a strategy for fighting Bruce than flailing towards him and slapping him.
• Early-Bird Cameo: Fong Ling encounters this thing before Bruce does, but it ignores her due to being incapable of sensing her presence.
• Eye Scream: It's blind as a result of its eyes being surgically removed during its development. It compensates with its heightened sense of hearing.
• Fat Bastard: Pluto is a grotesque mass of flabby flesh.
• Lobotomy: Having an iron rod hammered through his frontal lobe by Umbrella probably didn't do many favours for his intelligence, even without the t-Virus degrading it further.
• Sense-Impaired Monster: It's a heavily-mutated human who lacks eyes but developed exceptional hearing as a result. He serves as one of the game's bosses, and is rather tricky to take down if Bruce didn't find the silenced handgun.
• Was Once a Man: Pluto was once a convict on death row Umbrella took in for experimentation, with the researchers lobotomizing him and surgically removing his eyes. Among other things, this explains its blindness and lack of brainpower.

Nautilus

Once a failed B.O.W., the creature known as Nautilus was dumped into the sewers of the Waste Disposal Facility adjacent to the Atlantic Biosphere facility. There, it mutated into a horrific parasite that spawns offspring known as Torpedo Kids. Only two are known to have existed.

---

• Body Horror: It's some kind of sea urchin monster with a human face in the center. The Torpedo Kids it spawns resemble human fetuses with faces contorted to appear as though they're screaming in agony.
• Mook Maker: Nautilus doesn't attack, nor is it capable of moving from its station. Its only purpose is to spawn the Torpedo Kids, swimmer-like abominations that hound the player as they trek the sewers.
• Optional Boss: The player doesn't gain anything from killing the two Nautilus other than stopping Torpedo Kids from spawning.

Halbert

The last of the major failed B.O.W.s in the Atlantic Biosphere facility that Bruce encounters.

---

• Big Creepy-Crawlies: It's a B.O.W. that was created by splicing the shell of a horseshoe crab with cockroaches.
• Meaningful Name: Named after the halbert (also called a "halberd"), a medieval pole-based weapon. The drones primarily attack through stinging.
• Mix-and-Match Critter: A cockroach and horseshoe crab combined to make a wasp-like abomination.
• Mook Maker: The Halbert spawns drones that will assail the player; it doesn't attack its own.
• Stationary Boss: Despite having wings, Halbert is incapable of moving from where it is located.

Resident Evil: Revelations 2

The Afflicted

Afflicted; AKA: Rotten, Ironhead, Sploder, Vulcanblubber

A standard Afflicted and Rotten

^Ironhead

^Sploder

^{Vulcanblubber}

The t-Phobos virus was an experimental retrovirus that Alex Wesker created in an attempt to produce superhumans, mostly in an effort to save herself from her terminal illness. The experiment was a complete failure, resulting in all but a few of its victims becoming monsters driven by rage.

---

• Achilles' Heel: Vulcanblubbers are very durable otherwise, but massively vulnerable to headshots. A few good shots to their heads will put them down very quickly.
• Action Bomb: The Sploders are bloated Afflicted that explode in close proximity, causing heavy damage and blinding their victims with pus.
• Ax-Crazy: The Afflicted are not zombies, sans the Rotten, they are humans driven feral by a combination of the torture they suffered as regular people and the t-Phobos virus responding to that fear.
• Body Horror: They all display signs of the extreme torture they suffered at Alex's hands, being mutilated and mangled beyond repair. t-Phobos infection has also discolored their skin color into a disgusting orange hue, making it appear as though most Afflicted are literally rotting. Special mention, however, to the Sploder, an Afflicted mook covered in and inflated by disgusting tumor-like sacs ready to violently explode.
• Degraded Boss: The Vulcanblubber is the climactic boss of Claire and Moira's half of Act II. It can later be infrequently found as an Elite Mook.
• Elite Mook: Ironheads serve this role, being more common than Vulcanblubbers, and tougher than their fellow Afflicted — including No Selling the One-Hit Kill mechanic — but still not a "true" mini-boss.
• Our Zombies Are Different:
  • The Afflicted are Technically Living Zombies, being humans mutated and driven violently insane by exposure to T-Phobos, which has also made them highly averse to the light. If killed or left to starve, they can eventually come back from the dead as decayed, black, skeletal "real" undead zombies called the Rotten.
  • Revenants are amalgamations of corpses and metal pieces animated by Uroboros, giving them an appearance rather like Frankenstein's Monster.
• Stout Strength: Vulcanblubbers, as their Meaningful Name suggests, are about twice as tall as a human and at least four times the girth.

Glasp

An unintentionally created monster as a side-effect of t-Phobos experimentation on humans. No one truly knows why it came to be, nor why it has its appearance and biology when gene splicing wasn't involved.

---

• Body Horror: A giant, bloated fly-like monster with vague human characteristics, which ramps up the Body Horror factor up to eleven: arms and legs converted into multiple, jointed insect limbs with its still human feet dangling off two of them and a mouth grown out of the back of its human skull. Worst of all, it covers its victims in what appear to be maggots upon killing them to procreate.
• Giant Space Flea from Nowhere: Apart from the fact that files explicitly stating their reasons for being are a mystery, they inexplicably introduce themselves to Barry with no foreshadowing or warning. Almost literally too, considering they closely resemble fleas.
• Invisibility: Glasps are infamously terrifying for being invisible by default. They're only made visible just as they perform their One-Hit Kill, are indiscriminately shot at and luckily hit, or via Natalia's ability to sense them.

Other Media

A-Zombies

Appearances: Vendetta

A-Zombies are the primary products of the Animality Virus, or simply the A-Virus, a genus of the Progenitor virus. They are the first zombies to be manufactured as fully controllable B.O.W.S. than being incidental byproducts of terror attacks.

---

• The Berserker: They're even more ferocious than the C-Zombies, a single one of them being enough to overwhelm a squad of trained soldiers.
• It Can Think: Subverted. Unlike the C-Zombies, they can't think, only be remote controlled to distinguish friend from foe.
• Plague Zombie: Like the t-Virus variants and unlike C-Zombies, they are capable of infecting others with bites and scratches.
• Technically-Living Zombie: A-Zombies that haven't been produced from corpses are still alive and curable. Rebecca manufactures a vaccine that can reverse their state, and it's hosed all over New York at the end.
