==Summary==
William Birkin was a researcher and virologist working for the Umbrella Corporation in Raccoon City, developing the T and G-Viruses among many other bioweapons. Bitter over Umbrella's refusal to give him a promotion, he slowly sabotaged his facilities and planned to betray them, but before he could do this, Umbrella intervened, and he was gunned down. Enraged, and barely alive, Birkin injected himself with the G-Virus, mutating into the monstrous G and causing the outbreak.

Durability: Likely Small Building level | At least Small Building level | At least Small Building level, likely higher (He was only killed by NEST's self-destruction). His regeneration makes it difficult to kill him.
Stamina: Very high, though he can be knocked unconscious by extensive damage, leaving him to rest until he regenerates and transforms once more.

Weaknesses: As he succumbs to the G-Virus, Birkin slowly loses all his intelligence. The G-Virus is only compatible with those closely related to him by blood; in his case, this is only his daughter. As he transforms, severe injuries will ultimately cause him to mutate into a giant, mindless blob that can barely move.
