Created by writer Chris Claremont and artist Brent Anderson, he first appeared in Marvel Graphic Novel #5. His character is later re-introduced in All-New X-Men #19 and was officially given his name "Jason Stryker" in that version.
Jason was born after his parents, William Stryker and Marcy Stryker, crashed their car in the Nevada desert. William was stationed on a nuclear testing facility when Marcy was pregnant. Alone in the desert, Marcy went into labor and Stryker was forced to deliver their baby. When Marcy woke from unconsciousness and asked if their baby was okay, Stryker snapped Marcy's neck. Stryker saw his son's birth as a sign from God, turning into a religious fanatic that ensures the genocide of all mutants. However, Jason was kept alive and Stryker resorted to A.I.M. to treat his son's mutant condition. As an adult, Jason joins the Purifiers to continue his father's work and faced the original X-Men's time-displaced version. Jason was defeated and arrested by S.H.I.E.L.D.
Powers and abilities
Jason Stryker possesses the ability to project a blinding white light from his body that is powerful enough to knock several people unconscious. His mutation was apparently initially unstable, as he was born horribly deformed and was also implied by his father to be deathly ill, afflictions that A.I.M. was able to somehow alleviate, though with side-effects such as chronic headaches and insomnia.
The Ultimate Marvel iteration of the character is Reverend William Stryker, Jr., the son of William Stryker, Sr. and the leader of an anti-mutant coalition armed with Sentinel technology that is possibly stolen from S.H.I.E.L.D. He has a Sentinel tech body armor that resembles Ahab from the mainstream Marvel universe and various alternate realities. His wife Kate Stryker and son John Stryker are killed during the "Ultimatum" wave through New York, leading to his hatred against mutants. His forces later attack Juggernaut and Rogue. He is later seen with the advanced Nimrod Sentinels. When he attacks Times Square, executing mutants in public, the X-Men appear and the Shroud kills him via a phasing arm through his abdomen; it's revealed that he's a mutant with the power of technopathy. His father used medication in order to suppress his abilities but his powers manifest with his last breath and manipulate a wave of Nimrod Sentinels to kill every mutant on the planet. It is revealed that his last act left his brain-patterns imprinted on the Nimrod Sentinels as Master Mold, and continues to be a threat to the X-Men. Stryker led an assault against Kitty Pryde's team of mutants before Pryde managed to damage Stryker's machine body enough to destroy him permanently.

Film
Jason Stryker appears in X2, portrayed by Michael Reid McKay. This version is a mutant with the ability to project illusions into people's mind through eye contact, and he also has heterochromia. Years ago, he is sent to the Xavier institute in hopes of curing him, which only made him accept his mutation and angered his father when told there was no cure. One year after Jason returned, he blamed his parents for being a mutant and then tortured the two by planting telepathic illusions until his mother committed suicide by drilling into her own brain. William Stryker then gave his son a lobotomy to make more docile. As Mutant 143, he's wheelchair bound and mute, and is used by his own father to make a secretion from his son's brain to inject into other mutants to control, such as Nightcrawler, Lady Deathstrike and the same Jason. Stryker's control over his son was powerful; all that needed to be done is whisper commands to Jason and the action would follow without question. He uses telepathic illusionary powers to appear as a little girl and is strong enough to convince Professor X to use Cerebro back at the Xavier institute. His little girl illusion has Professor X locate 'all the mutants' around the world via Cerebro. When the X-Men began an assault on Stryker's secret lair at Alkali Lake, Stryker commands Jason to use the illusion to urge the Professor to find and kill all the mutants. However, Mystique, impersonating Stryker, commands Jason to change the target to all the humans. His little girl illusion also tried to deceive the X-Men but Storm's abilities interrupted Jason's illusion, freezing his own secretion of the whellchair. Jason was last seen inside the replica Cerebro chamber and gets left to drown when the Weapon X underground complex was flooded by Alkali Lake.
Jason Stryker is featured in , voiced by Steve Blum and by Grey DeLisle. He survived the flooding of the Weapon X underground complex as his psyche now fractured into two halves: a good half who has been appearing to Nightcrawler and an evil half that is behind Master Mold's control to kill the X-Men. Jason's good half helps Nightcrawler to disable Master Mold. Nightcrawler attempts to save Jason as Master Mold begins to collapse, but Sabretooth abducts Jason and attempts to make an escape. Wolverine tracks Sabretooth's scent and confronts while Nightcrawler escapes with Jason. Jason dies thanking Nightcrawler for saving him.
