named "P. Xavier." One of the writers noted that this character is Xavier's twin brother who was born brain-dead (due to Professor X's amount of power). Since P. Xavier was born brain-dead and stuck in a coma for a long time, Charles Xavier can't walk in his brother's body and uses his old wheelchair. Xavier's return is an example of a comic book death, which refers to comic book characters getting killed off but not staying dead permanently. This scene was not in the script but was secretly added during filming. X-Men Origins: Wolverine Xavier appears briefly at the end of X-Men Origins: Wolverine after Wolverine frees a group of young mutants (including Cyclops) from Stryker's Weapon X lab on Three Mile Island, with Stewart digitally de-aged. They try to escape from the facility but get lost until Cyclops hears a telepathic voice which guides them out to safety. Xavier then takes everyone into his helicopter, presumably to his school for mutants. As in the opening of The Last Stand, Patrick Stewart was digitally de-aged, and Xavier is able to walk and does not use a wheelchair. As an explanation, he might have created the illusion that he is standing in various scenes when in reality the character is only present by telepathic projection. X-Men: First Class James McAvoy portrays the young Charles Xavier / Professor X in X-Men: First Class. He serves as one of the two protagonists of the film along with Erik Lensherr / Magneto (Michael Fassbender). As a young man, he befriends and adopts Raven Darkhölme (Jennifer Lawrence), later known as Mystique. He earns his doctorate after doing research on genetic mutation at Oxford, which brings him to the attention of CIA agent Moira MacTaggert (Rose Byrne). The Central Intelligence Agency provides him access to Cerebro, which he uses to locate and recruit other mutants for the government. Around the same time, he meets Erik Lensherr after saving him from drowning in a botched attempt to kill Sebastian Shaw (Kevin Bacon). Xavier and Lensherr become friends and together they located mutants for the CIA. Once the team is assembled, Shaw and the Hellfire Club attack the CIA facility, kill all the human personnel including one of Xavier's recruits, and persuade another to defect. Xavier retreats with the survivors to his Westchester, New York mansion to train them as an independent team of operatives to prevent nuclear
