G

First appearance: Resident Evil 2

G

Unlike its cousin, the T-Virus, whose effects end after a single generation, the G- Virus affects its host at the genetic level, evolving and changing DNA to match its needs. It can even reproduce. It is perhaps the most evil invention of the century. Its inventor, Dr. William Birkin, injected himself with the G-Virus and became the creature now known as G. The new, inhuman William lost all sense of reason and humanity, resulting in a violent, dangerous creature that existed only to destroy. After granting its host an unbelievably strong life force and amazing strength, the G-Virus continued to invade and transform the flesh of its host body.

Its first form leaves its host with a moderately human appearance, but this is only the first stage in its horrific evolution. The effects of the G-Virus on its host's right arm give it superhuman strength, but also a giant eyeball growing from the shoulder. The eyeball functions just like any other natural organ.

In its second form, the G-Virus has spread throughout the lower body as well, causing asymmetrical mutations. William Birkin's face has apparently been sucked into the heart area, and a new head has grown in its place. The surprising thing about this head is that it already contains the G-Virus's brain. Other mutations involve a different bone structure, large claws growing out of the right hand, and a larger version of the eyeball on the right shoulder.

First Form G

The beginnings of the asymmetrical mutations. It still retains the appearance of its host, William Birkin, but it also contains inhuman properties. These include a powerful right arm so strong it can break iron, and the violent, monstrous nature of an enraged beast. In its third form, the mutations have spread even further, including a new eye on its left thigh. In addition, it has grown two new arms and the larger, almost wing-like arms have moved to its back. Changes have also begun in the heart and other organs. After suffering a threat to its life, G heals its injuries while continuing its mutation to something far removed from its original form. It has become a beast that crawls on four legs. Considering the extent of the G-Virus damage, this can be considered a natural evolution. In this form, the head and chest have morphed together, the large jaw has become the most prominent characteristic, and its agility has increased considerably. But these changes come at a price.

The fourth form requires constant energy to remain active, leading it to eat more. The more it eats, the more it mutates. The result of these changes is G's fifth form. In this form, its arms have changed into tentacles, its body has grown soft and pulsing like that of a mollusk, and the remains of a not-yet-fully digested creature can be seen. Its endurance and durability is on the same level as its fourth form, and it's difficult to inflict critical damage on it, even with heavy weaponry.

Eventually, G was destroyed in its fifth form, but its absence leaves us with new questions. For example, we have no idea whether or not its fifth form would have been its final form or not. Left to its own devices, G could have evolved to a sixth, seventh, or even eighth form. Indeed, there are no factors indicating that G's evolution would have come to a halt anytime soon. At any rate, since all those involved with G's creation are now dead, a full investigation into G and its potential will soon be necessary.

Second Form G

A progression of the mutations evidenced in its first form, including the appearance of new organs unique to G. Its mutations have spread to include new bone and skin structure, and a whole new brain to go with its new head.

Third Form G

All traces of William Birkin have now been erased, and its primary arms have moved to the back, resembling demon wings.

Fourth Form G

An advanced stage, where the G cells have spread throughout the entire body and induced a number of new mutations. The result is a body too heavy to support on two legs, which is why it changed to four-legged movements. It has evolved so far as to be a prime energy source for Zombies and Lickers.

Fifth Form G

An even further mutation into what appears to be a living lump of flesh and teeth. It possesses a soft, malleable body that allows it to squeeze through narrow corridors. To attack, it whips its various tentacles around and bites its target.

G Adult Body

A new kind of creature, born from an organism genetically rejecting the G-Virus. It's the result of forced, false reproduction on the part of the G cells, destroying the host Body and rendering it useless.

Rejecting the G-Virus

G: The new creature created by Umbrella, but never officially recognized by them. But it's not a foregone conclusion that G will mutate the body of its host.

If the genetic incompatibility between G and its host is insurmountable, the host body will reject G from its system. When this happens, the G cells will forcefully reproduce and spread throughout the body, in what is called false reproduction, and the result will be the G Adult Body.

When this happens, a part of the host body will remain, and a number of aspects from a complete G conversion become apparent. This creature will also reproduce G Young Bodies from its mouth. These are little reproductions of G with no ability to reproduce themselves.
