Alex Wesker was Subject no. 12 in the "Wesker Project", and one of only two survivors of the project to survive the injection of the Progenitor virus strain. 1
History
Alex was originally born to parents of superior intelligence, and was later taken in by the Umbrella Corporation to be indocrinated by Oswell E. Spencer who attempted to use the project test subjects to create a perfect model for his image of a new, superior human race. Like all the other test subjects, his surname came directly from the surname of the chief researcher of the project at the time. He was given a special eduation, and possessed superior intellect and leadership skills.
In 1998, Alex was administered the Prototype virus, an experimental strain of the Progenitor virus. He survived the injection, and became a member of the Umbrella Intelligence Department and worked secretly for Spencer after gaining his trust, becoming the chief researcher of the Wesker Project. On August 28, Alex filed a report on the status of the Wesker Project in response to the death of Albert Wesker. 2
In 2005, Spencer enlisted the help of Alex to develop a new virus from the Progenitor virus which could halt or reverse the effects of ageing, in order to give Spencer the power of immortality. He was appointed as chief researcher and received all the funding, equipment, supplies, researchers and test subjects necessary for the development of the virus, based on an abandoned military institution on an isolated island in the South Seas. 3 4 Eventually, Alex completed development of the virus, but betrayed Spencer and disappeared from the island. 5
His current status is unknown.
