Jason Stryker is William Stryker's son and appears in Xmen 2 UNITED and Xmen origins: Wolverine. He is AKA Mastermind and was an earlier pupil at Mutant High. However he grew a hatred against his parents and planted horrible illusions in their minds. His mother later on comitted suicide and his father brainwashed him to do whatever he desires. William Stryker uses Jason's spine fluid to hypnotize other mutants. However, it didn't work on Charles Xavier so Jason Stryker had to fool Xavier into using Cerebro by creating an illusion in which he'd be a little girl wanting to find all the mutants.
