Wolverine. Xavier is able to control both Sabretooth and Toad (Ray Park) at the same time and speaks through them to try to talk Magneto out of his plans against humans. Xavier uses Cerebro to locate Rogue when she runs away but is poisoned when he uses it later due to it having been tampered with by Mystique (Rebecca Romijn). At the end of the film, he recovers and advises Wolverine to search Alkali Lake for answers to his past. X2 Stewart reprises his role as Xavier in X2: X-Men United. Upon learning that the mutant Nightcrawler (Alan Cumming) attacked the President of the United States, Xavier sends Storm and Jean Grey (Famke Janssen) to bring him in for questioning. Xavier and Cyclops leave Wolverine in charge of the school so they can visit Magneto in the plastic prison he was placed in at the end of X-Men. In Magneto's cell, Xavier learns that Magneto was brainwashed by William Stryker (Brian Cox) and forced to tell Stryker all about the school and Cerebro. Xavier realizes too late that it is a trap and is captured. He wakes up in Stryker's underground test facility, tied to a chair and fixed to a device that restricts his mental powers. He is left in the room with Jason Stryker (Michael Reid McKay), William's son and a powerful illusionist who had previously been a student at Professor X's school. Now brainwashed by his father, Jason traps Xavier into various illusions, keeping him in one where Xavier is back in the school, now completely empty, and Jason is portrayed as a scared little girl. To comfort the "girl" and find his students, Xavier goes to use Cerebro. The audience discovers that Xavier was captured to power a makeshift Cerebro created by Stryker. When Xavier's powers are magnified by Cerebro, he can locate any mutant in the world. Through intense concentration, he can kill humans or mutants. Under Jason's illusion, Xavier is tricked into concentrating on all of the world's mutants, nearly killing them. He then switches to attacking all of the world's humans after Magneto – who is unaffected due to his helmet that blocks telepathy – confronts and threatens Jason. Nightcrawler and Storm rescue Xavier from the illusion. They then fly to Washington to warn the president against the possibility of a mutant/human war.
