He is a mutant who can manipulate other mutants due to his psychic abilities and to plant illusions inside others minds, He helps his father in his main goal to eradicate all the mutants on Earth ,and he aids him by manipulate and brainwash friends of X-Men.

In the movie ,he was portrayed by actor Michael Reid McKay. while in the video game ,he was voiced by Keely Purvis.
PastJason was Also known as 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 committed 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 (so Xavier would concentrate and kill all of the mutants). Later on Magneto enters the room along with Mystique, being immune to Jason's attack due to his helmet. Magneto makes Mystique transform into William Stryker. She tells Jason to tell Xavier to find all humans instead (to kill them). Jason follows "his father's" orders and tells Xavier to find all humans. Later on Storm and Nightcrawler enters the room. Jason attacks them with an illusion of an empty room with only one little girl inside. Nightcrawler falls for it, but Storm knows it's a trick and creates a cold storm that makes Jason lose focus so Xavier realizes it's an illusion. "Jason," Xavier says with a somehow disappointed voice. The illusionary girl starts yelling "Dad is going to be so mad at me!" and starts screaming, which breaks the illusion. Xavier turns around and looks at Jason with a sympathetic look. Then Xavier leaves the room along with Nightcrawler and Storm and Jason is left behind to die as the dam falls apart.
X-Men 3: The Official GameJason appears as the final boss and as the main antagonist in the video game.
Jason somehow survived and tried to finished what his father started. He did this by unleashing the Master Mold, a giant robot that could create Mutant-Eliminating Robots known as Sentinels.

When the X-men were attempting to shut down and destroy the Master Mold, It turns out that Jason as a second personality, one that wanted to help Nightcrawler destroy the Master Mold. After the Master Mold was destroyed, Jason told Kurt to leave his body so he could finally be at peace.
