his mobility from Hank McCoy/Beast's (Nicholas Hoult) serum, but at the cost of suppressing his mutation. In addition, Xavier is living under the care of McCoy, is impolite to people, uses profane language, occasionally behaves violently, and drinks heavily to cope with his failures. By 2023, the Sentinels have decimated the mutant race and virtually conquered Earth, forcing the X-Men to seek a new method of combating their threat. With Kitty Pryde (Elliot Page) having developed the ability to project an individual's consciousness back into their past selves, Xavier proposes that he be sent back into his past self in 1973 so that he can prevent Mystique from killing Bolivar Trask (Peter Dinklage) after he proposed the Sentinel program, believing that this death is the primary catalyst for this timeline.

Although Magneto nearly triggers a mass slaughter when he takes control of the Sentinels during their demonstration in Washington, D.C., Mystique
