Editing Resident Evil (section)

==Man-Made Pestilence==
The basic core of the RE universe is the idea of infectious agents - traditionally viruses, but the series has experimented (no pun intended) with other vectors - that can twist living creatures into unnatural monsters. So let's try and break down the major mutagens of the series, shall we?

'''Progenitor Virus:''' The original, in more ways than one. This mutagenic virus was native only to a small cave system in West Africa, and was literally the birth of the Umbrella corporation. Compatible hosts typically become stronger, tougher, and, in animals at least, much larger. Incompatible hosts end up dead. Largely considered to be rather weak as a B.O.W producing agent; supplanted by its successor, the T-Virus.
* '''T-Virus:''' The result of combining Progenitor Virus and Leech DNA, this was the creation of Dr. James Marcus. Much more virulent and with more powerful mutagenic properties than its predecessor; it even allows for the successful fusion of genes across species, allowing for the creation of the Hunter line and the experimental Chimera B.O.W. One disadvantage is that it introduces uncontrollable necrosis (rotting flesh) and a sharp loss in intelligence. Humans exposed to the T-Virus typically become the iconic zombies. This was the mainstay of Umbrella's research going forward.
* '''T-Veronica Virus:''' A fusion between the T-Virus and an ancient virus that Alexia Ashford discovered inside of a fossilized queen ant. Much more potent than the regular T-Virus. Infectees often display arthropod or even plant-like traits. Prolonged exposure to the virus without being overcome by it - say, through cryogenic suspension or a prolonged regime of organ transplants - causes it to become symbiotic with the host, granting them superhuman abilities.
* '''T+G Virus:''' An experiment in fusing the T-virus and G-virus that didn't exactly work out (it was meant to generate a bioelectrical current in the subject; suffice to say it failed most of the time). It was used only twice in the series, with the first B.O.W it created being a horrific failure (a Tyrant with tentacle-arms, no bioelectrical abilities, and a heart sticking out of its back) and the second turning a male victim into a female(?) Tyrant-like creature (one that could shoot lightning, no less).
* '''T-Abyss Virus:''' A fusion between the T-Virus and an unnamed virus discovered in a deep sea fish. Highly mutagenic; bestows increased aquatic affinity in infectees. Seems to be especially compatible with sea life; most infected become [[Deep One]]-like pseudo-[[Vampire|vampires]] or otherwise have their mutated states based on sea life of various kinds.
* '''T-Phobos Virus:''' Experiments with the T-Virus had suggested that there was a psychoreactive component to the virus - that is, the mutations were literally shaped by the subconscious mind of the host. T-Phobos is the product of experimentation and research into that aspect, creating a mutagenic virus that will affect you if you become too scared.

'''NE-Alpha Parasite:''' A macro-parasite engineered by the French branch of Umbrella, intended to grant greater control over (and durability to) B.O.W hosts by serving as a surrogate brain. Nobody knows ''how'' they cooked this up, but a popular theory (among fans and implied in-universe) is that it's an artificial recreation of Las Plagas. As the name might imply, this is the parasite that made Nemesis as smart and scary as he was.

'''G-Virus:''' A bizarre virus refined from an unnamed strain discovered in the body of Lisa Trevor after an attempt to infect her with the NE-Alpha Parasite failed. Incredibly mutagenic, granting the host constant bodily evolution and high regenerative abilities, but not terribly virulent, being almost incapable of spreading short of direct injection or being implanted with an 'embryo' from an existing G-Virus-infected creature. If anything, it's ''too'' mutagenic, [[Chaos Spawn|devolving the hosts into squamous masses of malformed meat]] once they experience enough trauma.

'''Uroboros Virus:''' Wesker's ultimate genocidal virus. If, on the literally millions to one chance you're compatible with it, you'll gain superpowers of a similar kind to Weskers's. Otherwise, you just end up as a mass of slimy black flesh-eating worms. Also capable of causing some impressively horrifying mutations, such as turning a cockroach into a seven-foot nightmare with an instant kill attack ''purely on accident''.

'''C-Virus:''' A super-virus cooked up by Neo-Umbrella, intended to be superior to the T-Virus and G-Virus. Direct injection turns victims into J'avo; aerial infection turns them into C-Viral Zombies. Had an enhanced variation that could be made by adding G-Virus antibodies to the C-Virus' components, but all three samples of it were used during its debut game. Unlike the previous viruses, the C-virus cannot be transmitted via bites or scratches, so attack victims are not given a death sentence. So far, the only known vectors of transmission is direct injection into the host, or being exposed to virus-contaminated air or water. Also notable for making the hardcore scientists weep and [[rage]] due to stretching (or breaking, in the case of the advanced version,) the law of conservation of mass, by doing things like turning a normal human (without any extra mass being added) into a fuckhuge mutant T-Rex with an eyeball in its mouth. 

'''Las Plagas:''' A macroparasite discovered somewhere in remote Spain. Although buried for centuries, it was dug up by a cult that worshipped it; "Los Illuminados". Whilst it has some mutagenic properties, mostly it acts to turn hosts into pack-hunting neo-zombies. This makes the hosts unusually tanky compared to "standard" zombies, as when the host is injured, the Plaga may burst out of them to continue fighting - luckily, they can't stand UV light, so a simple flash grenade will kill them. Infection is also notably slow compared to Umbrella's viruses, requiring the injection of Plaga eggs and taking about a day or so for the Plaga to hatch, mature, and seize control. RE5 introduced the genetically engineered Type-2 Plaga, which reproduces more quickly and can directly infect hosts by 
having an infectee spit up a larval Plaga and shove it in a victim's mouth. It also introduced the Type-3 Plaga, an attempt to create an even more virulent strain that turned out to make its hosts even crazier than regular Plagas, and was also [[Female Space Marines|lethally genetically incompatible with female hosts]].

'''A-Virus''': A watered-down version of the T-Virus, created by mixing the baseline t-Virus with material from Las Plagas. Infection creates "Zombies", which are essentially Ganados (Plaga infectees) mixed with "standard" zombies, being much faster and more intelligent ([[What|even being able to speak and co-ordinate]]) though with the same aggression and hunger as regular zombies. Infamously skubby for breaking RE canon in a ''big'' way by allowing the zombies it created [[What|to be turned back into humans]] (as opposed to the other viruses, where you're completely screwed after you turn zombie), though it can mostly be ignored due to showing up in only one movie and then never being mentioned again.

'''Mutamycete:''' Aka "The Mold". Symbiotic fungus bio-weapon linked with the B.O.W E-001, aka "Eveline", who can generate humanoid servitors out of fungal strands and control the minds of anyone infected with the fungus. RE8 reveals it's actually a derivative of a naturally occurring parasitic mold with [[psionics|mind-absorbing capabilities]] referred to as the '''Megamycete'''.

'''Cadou:''' A macroparasite derived from infecting a parasitic nematode with Megamycete, created by Mother Miranda as part of her efforts to revive her daughter. Responsible for the Lycans, the four houses, and the other monstrosities faced during the events of Resident Evil 8. Exactly whether the victim becomes a neo-[[Vampire]] in the style of Lady 'Step on me Harder' Dimitrescu, gains some kind of unique mutation, or devolves into a half-mindless not-[[Werewolf]] appears to be down to genetic factors.
