- “You were even more frightened of him than I was. You know, just one year after Jason returned from your school, my wife... You see, he resented us. He blamed us for his condition. So he would toy with our minds, projecting visions and scenarios into our brains. Well, my wife, in the end, she took a power drill to her left temple in an attempt to "bore" the images out. My boy, the great illusionist!”
- ―Colonel William Stryker to Professor Charles Xaviersrc
Jason Stryker was a mutant with the ability to create mental illusions within anyone he makes eye contact with, as well as persuade them to speak or perform actions without inhibitions.
Jason Stryker was born in 1963, to William Stryker and his unnamed wife.
- Illusion Generation - Jason Stryker was able to create psychic illusions and also exert some control over those affected by his illusions. By the time of his father's attempted mutant genocide, these illusions were at least facilitated by a gas harvested from Jason's body. Jason also produced a fluid from his brain that could be used to mentally enslave people.
- Jason's illusion-based powers in the film was based off one of the other X-Men villains Mastermind, a member of the Hellfire Club.
- Jason's comic book counterpart was originally a one-time character in 1982 that was born as a mutant and supposedly killed by his father who took it as a sign of God to begin his holy crusade of mutant genocide. In 2013 this was retconned, and instead it was established in the All-New X-Men series that his father took him to A.I.M. to have his powers suppressed, and in the present he has become the new leader of the Purifiers to continue his late fathers' work of exterminating all mutants.
- Jason's hetrochromia and mulitple personalities (Older Jason and Younger Jason) are somewhat similar to David Haller aka Legion who possesses both Hetrochromia and Schizophrenia/Split personality disorder.
- Amy and Jason Stryker were the only two characters to have heterochromia, which made one of their eyes blue and the other green.
