List of Resident Evil series creaures

This article lists creatures that appear in the Resident Evil franchise, including video games, films, novels, and replicas.

Hunter
The Hunter is one of the first original monster designs in the series. The Hunters are established in the games as a breed of artificially-created half-human/half-reptilian creatures with sharp claws created by the Umbrella Corporation. They are introduced in the original Resident Evil as replacement enemies for the zombies when the player revisits the mansion during the later part of the game. According to a file in Resident Evil: Survivor, hunters prefer to hunt in packs.

The Hunters are recurring enemies throughout the series and sub-species of Hunter are introduced in later games.

Resident Evil 3 introduces two new type of Hunters: Hunter Beta and Hunter Gamma. Hunter Betas are the successor of the original Alpha model from the first game. They are very distinct from Alpha Hunters as their upper body is covered in red tumor-like bumps. Hunter Gammas are an amphibian-based model nicknamed "Froggers", which are endowed with long tongues, and are capable of swallowing the player.

Resident Evil Code: Veronica introduces the Enhanced Hunters, who are controlled by Wesker; and the Sweepers, which are Enhanced Hunters with venomous claws. Resident Evil: Outbreak introduces the Hunter R, an experimental form of Hunter Alpha. In Resident Evil: The Umbrella Chronicles, the Hunter R is shown to be Umbrella's mass-produced design.

Resident Evil: Dead Aim shows another form of Hunter, the Glimmer, which prefers to hunt in the dark, with only its two bright, shining eyes as evidence of its position.

Wasps
Wasps thrive in the Arklay Research Center's Residence, and have grown to a huge size from the T-virus. They are no different in appearance from a normal wasp except for the size, but they do build a large hive in the residence. Their stings are strong enough to penetrate bone, and the venom can kill in minutes if not treated.

Chimera
A Chimera (taking its name from the mythical Greek creature) is a BOW that was created by inserting fly DNA and the T-virus into human tissue. They were being manufactured inside the Arklay Research Facility's basement lab and adopted that section of the facility as their habitat during the mansion incident. Aside from their fly-like appearance, the Chimera's most notable characteristics is their ability to walk over walls and ceilings.

The Chimera was the only other BOW, besides the Hunter and Tyrant, that was created through genetic manipulation. Their wings were too small to allow them to fly, and they lacked a fully developed exoskeleton. Even though they showed signs of notable resilience, their intelligence was little more than that of an insect. Due to their many flaws, further research into more advanced forms was never conducted, and the Chimera's basic form was never refined. The Chimera also mutates quickly into a more advanced version of its self if it feeds on "fresh" DNA which allows it to move more rapidly, use more force and to grow bigger in size.

Plant 42
Plant 42 is a large plant infected with the T-virus, and it was part of the experiment on botanical subjects by Umbrella researcher Henry Sarton. With a massive flower-like nucleus protected by distorted petals and extremely powerful vines. After its DNA reconstruction by the T-Virus, its behaviour suddenly became aggressive, and its appetite became carnivorous. It used its bloodsucking tendrils to completely sap the researchers of their blood. Plant 42 grew to invade the residence, by climbing to the top of the ecosystem, and it completely took hold of the dormitory. In the library room, using its roots to feed on the water in the Aqua Ring beneath it. As noted in a chemistry report lying around in the residence, the plant is vulnerable to a particular chemical, named V-Jolt or UMB Nº16. Up until its destruction at the hands of S.T.A.R.S., its roots were firmly in place throughout the entire building.
 * Appears in: Resident Evil (all versions), Resident Evil: Outbreak and Resident Evil: The Umbrella Chronicles.

Yawn
The Yawn is a giant and highly poisonous T-virus-infected snake.
 * Appears in Resident Evil (all versions) and Resident Evil: The Umbrella Chronicles. It is called Yawn due to the way it looks when it is about to bite.

Adder
A small snake that was not mutated extensively by the T-virus, and that holds none of the characteristics of more enhanced BOWs, such as Yawn. It has a poisonous bite, in addition to being small and hard to hit.
 * Appears in: Resident Evil (all versions) and Resident Evil: The Umbrella Chronicles.

Neptune
Neptune, named after the Roman god of the sea, is a BOW that was created by implanting the T-virus into a great white shark. It was created to test the effects of the virus on a sea creature. The creature was accompanied by two smaller offspring. During the viral outbreak in the facility, Neptune and its spawn were released from their water tanks by a scientist, which flooded the entire Aqua Ring. Two Neptunes swam in the river bordering Raccoon's University.
 * Appears in: Resident Evil (all versions) and Resident Evil Outbreak, and Resident Evil: Umbrella Chronicles.

Tyrant
A Tyrant is a fictional creature from the Resident Evil series. Tyrants make appearances in almost every Resident Evil game as antagonists. They are portrayed as biologically engineered super soldiers, used by the Umbrella Corporation. There are many types of tyrants as the result of several different experiments.

The desire to create an obedient super soldier lies at the core of Resident Evil's story line. Following the discovery of the Progenitor virus, the Umbrella corporation’s founders become eager to create a bioweapon that is both powerful and capable of following orders. Prior to the events of Resident Evil Zero, Umbrella used the Progenitor Virus to create the T-virus, which they believe can be used to manufacture powerful organisms. A problem with the virus’ compatibility with humans set the project back, as only humans with a very rare genetic makeup are capable of mutating into potent and manageable life forms. Umbrella eventually overcame this setback by resorting to using clones of Sergei Vladimir, one of their executives who happens to be genetically compatible.

The events of the  Resident Evil Zero and Resident Evil chronicle the Umbrella Corporation's development of a functional super soldier, known as a Tyrant. Though the early Tyrants are defeated in their first encounters, Umbrella manages to use the battle data from those defeats to produce other, more efficient Tyrants in the later installments of Resident Evil.

Numerous Tyrants have been created throughout Resident Evil's story line, each with its own defining characteristics. The games' creators have consistently depicted Tyrants as brutal, grotesque, and violent creatures. Additionally, the intelligence of Tyrants has varied. The first two Tyrants in Resident Evil Zero and Resident Evil are depicted as unintelligent, while Nemesis and the T-103 are shown to possess some intelligence and the ability to carry out specific instructions.

The weapons used by Tyrants have also varied. While most Tyrants in the Resident Evil series rely on sheer physical force to subdue opponents, Nemesis is able to use a rocket launcher. Other Tyrants, like the T-091, T-092, and the T-078 Tyrants from the Resident Evil: Dead Aim and Resident Evil Code: Veronica games are able to utilize tentacles, energy attacks, and battering rams.

GameSpot listed the Tyrant in their "Top 10 Video Game Villains" article at number ten, stating "When a game boss is first introduced with a line like, 'All people deserve to be eaten,' you know you're in trouble."

Ivy/Poison Ivy
Ivies are the results of Umbrella experiments on plants, mostly derivative from the Plant 42 experiment. They are bipedal green plants with arm-like vines and a large orange flower. Their main method of attack is to whip their target with their vines. They can also attack at range by spitting acid.

Poison Ivies have slightly different coloration than their counterparts and are physically tougher. The most notable difference is that the acid they spit is now poisonous.
 * Appears in: Resident Evil 2, Resident Evil: Survivor, and Resident Evil: The Umbrella Chronicles.

Grave Digger
A huge worm-like creature. Exposed to the T-virus, the worm has mutated to enormous size. It retains the ability to burrow underground, and it prefers a subterranean environment, although it will surface if hunger overwhelms its natural instincts. It usually attacks by lunging or biting, using its huge bulk to force its prey into a corner, where it can trap and devour it.
 * Appears in: Resident Evil 3 and Resident Evil: The Umbrella Chronicles.

Infected Bat
The Infected Bat is a large vampire bat infected with the T-virus, seen inside the cathedral in Umbrella's Management Training Facility.
 * Appears in: Resident Evil 0, Resident Evil Code: Veronica, Resident Evil: The Umbrella Chronicles.

Mimicry Marcus/Leech Zombie
When a large enough group of leeches come together, they assemble into a humanoid form, named Mimicry Marcus due to its tendency to take on the shape of James Marcus. Its limbs can extend to strike at targets. If it grabs a hold of a target it will soak it with acid. When killed, its upper half is destroyed and its lower half chases the player, attempting to burst and inflict damage.
 * Appears in: Resident Evil 0, Resident Evil: The Umbrella Chronicles''

Eliminator
Primates infected with the Progenitor strain exhibit rapid development of excess muscle tissue, resulting in visible tearing to the subject's skin. Further exposure causes a rapid increase in strength, agility, stamina and aggression, resulting in a deadly and efficient killer.

Although initially deemed a successful product, the Eliminator is found to have undergone significant decline in overall intelligence, which was supposed to be its greatest asset to Umbrella's BOW program. Mass production of the Eliminator is canceled and only a handful of specimens are preserved for further testing and research. Marcus turns his attention to the potential that human subjects present as T-virus hosts, later unwittingly providing William Birkin and Albert Wesker with the first scraps of information pertaining to the creation of the Tyrant-class BOW.
 * Appears in: Resident Evil Zero, Resident Evil: The Umbrella Chronicles.

Leech
There are two kinds of infected leeches through the Resident Evil story lines. The first variant is the one spawned by the Queen Leech, which features a notable increase in aggression and size, in addition to a strong communal hive mentality and the capability to bind together to form the Mimicry Marcus enemy. Marcus intended to use these leeches to infect the entire world with the T-virus. These leeches are infected with the Progenitor virus, which an infected Leech alters in its body to create the T-virus.

The second kind is featured in Resident Evil: Outbreak, in the "The Hive" scenario. These leeches are far more dependent on blood, are smaller, infected with the T-virus, and are unable to bind themselves in the same manner as the Resident Evil Zero leeches. Yet, when attacking a person in one of the rooms of the Raccoon General Hospital, they inflict "Bleeding" status, and can be distracted with transfusion bloodpacks. They can attack in large groups and consume their victim(s) with sheer numbers, keeping themselves attached, transforming them into the humanoid "Leech Man".
 * Appears in: Resident Evil Zero, Resident Evil: Outbreak, Resident Evil Outbreak File #2, and Resident Evil: The Umbrella Chronicles.

Nautilus and the Torpedo Kids
The Nautilus is a failed experiment that was supposed to be disposed of in Umbrella's island facility. They quickly reproduce and infest the underwater areas of the facility. Their offspring, dubbed "Torpedo Kids" due to their shape and behavior, live and grow in the water where they remain once they become fully grown Nautiluses.

Pluto
Pluto is the result of experimentation upon a human subject by Umbrella. The project involves the removal of the eyeballs and the use of muscle enhancers. The subject, known only as condemned criminal "Alpha", gains a massive amount of weight, and adapts to his blindness with an enhanced sense of hearing. In the "Experiment α Log", its author writes, "It recognizes precisely where a sound originates and its distance from that sound." The author later states in his log that Pluto escapes, suspending the project.

Queen Bee
The Queen Bee is a queen bee grown to terrifying proportions. There is also another form where it mutates further to give birth to millions of smaller infected bees and it grows to enormous sizes where it attempts to eat the player whole.

Depiction in films
In George A. Romero's unproduced 1998 screenplay for a Resident Evil movie, the screenwriter "incorporates the increasingly weird menagerie of the monstrous familiar to players: zombies, the gargantuan triffid-like Plant 42, a giant copperhead snake, and well as Hunters and the Tyrant."

Replicas and action figures
A number of the creatures have been made into replicas and action figures. The Resident Evil series of toys from Palisades Toys, based on a six-inch scale, includes a Soldier Zombie, Nosferatu, and Nemesis in Series One from Fall 2001; Mr. X (from Resident Evil 2), Zombie Cop with Licker (from Resident Evil 2), and Alexia (from Resident Evil CODE: Veronica) in Series Two; and Hunter and Tyrant in Series Three from Fall 2002.
