Prime universe
(Capcom's primary storyline)

Mary Grey was a student at Philosophy University and the true main antagonist of BIOHAZARD THE STAGE


Grey was subject to genetic engineering in a project led by Dr. Liam Howard on behalf of Philosophy University. The research boosted her intelligence to an IQ level rated as 230. While her greater intelligence made her an outstanding student, her social skills deteriorated and she became isolated from other students, such as Olivia Price and Lucas Butler.
