William Birkin

William Birkin is a villain in the Resident Evil franchise, appearing in the movies and video games.

He was a top scientist with the Umbrella Corporation, working with Albert Wesker.

Birkin had a wife, Annette, and a daughter named Sherry. After agents infiltrate his laboratory to obtain his G-Virus, he is shot and severely injured. He then uses a virus sample to inject himself with, which causes him to lose his mortality at the expense of becoming a monster, capable of implanting his embryos into others, with his daughter being a perfect match because of her genetic coding.

He is eventually defeated by Leon Kennedy aboard the getaway train, situated in the bowels of the facility beneath Raccoon City, which is later destroyed by a missile sent into the area to contain the outbreak.
