Biohazard

Birkin joined the Umbrella Corporation in 1977[4] at the young age of sixteen.[5] He was placed at the management training facility under First General Manager Dr. James Marcus. There, he became a close friend and rival of fellow researcher Albert Wesker, as they were both considered to be Marcus' top apprentices.[4] They were involved in the development of the experimental tyrant virus,[citationneeded] until the facility was closed down on July 29, 1978.[5]

Two days later, he and Albert were transferred to the Arklay Research Facility, where they continued their t-virus research and were assigned the roles of chief researchers of the facility by the facility's president.[5] It was around this time that Birkin began to obsess over the Ebola virus, which had recently been discovered inAfrica; Umbrella was, officially, researching a cure for the Ebola virus in the facility.[5] During their research into the Ebola virus, Birkin and Wesker were introduced to Lisa Trevor, who had been experimented on by Umbrella since 1967.[5] It was at this point that he and Wesker began to ponder on what Spencer's plans with the company really were.[5]
RivalryEdit Rivalry sectionEdit

On July27, 1981, Umbrella employed a ten-year old girl as a chief researcher.[6][7] Alexia Ashford, who was a granddaughter of Umbrella co-founder Edward Ashford, was of an unnaturally-high intellect thanks to the achievements of her father, Alexander.[8] News of her employment by Umbrella reached the Arklay Research Facility that very day,[6] having a heavy impact on the still-young William,[6] whotook to his own employment at the age of sixteen highly.[6] His frustration was worsened by discussions between older researchers, who held a high opinion for the Ashford family, even discussing over the potential of the young girl working at the facility.[6]

Despite his competitive rivalry with Alexia, his research yielded no results until he created the Hunter Bio-Organic Weapon (B.O.W.) in1981.[6] He became completely focused on his work and research and continued uninterrupted even after the announcement of Alexia's apparent death in 1983.[6]

He was "promoted" in 1988 to lead the "t" project (and completed the development of theTyrant-class B.O.W.) after he and Wesker helped to assassinate their former mentor, Marcus.[9] Following this, credit for the virus' creation was given to Birkin. [10] By this time, Birkin was already married to fellow researcher, Annette and the marriage had already produced a daughter named Sherry.[11]

When he and Wesker were conducting an experiment with an NE-α Parasite, they used a femalespecimen (Lisa Trevor) as a guinea pig.[12] Lisa was the only human test subject to fully accept the parasite - other hosts were killed shortly after implantation. Noticing her strange survival rate, Birkin examined her body structure and discovered that the variation of the Progenitor virus that was injected into her in 1967 had absorbed all the mutagenic organisms that she had been implantedwith since then and mutated into a new virus, which Birkin named the G-virus.[12]

He received approval from Umbrella's president, Ozwell E. Spencer, to initiate the G-virus Project; Wesker, however, did not approve, citing that random and uncontrolled mutations were unsuitable for a B.O.W. In 1991, Birkin and his wife were transferred to an underground facility established specifically for theproject. Birkin also bribed the chief of the Raccoon City Police Department, Brian Irons, to cover up the project, using his wife as the "middle man".

After his uptaking of "G", he passed the t-virus research down to one of his subordinates, Dr. Greg Mueller.
