the one who is actually sent backward in time to his "younger" body, director Bryan Singer described Pryde as the prime facilitator and it is Pryde's phasing ability that enables time travel to happen. In this film, the catalyst for the Sentinel-dominated future was Mystique's assassination of Bolivar Trask and her subsequent capture, with analysis of her DNA allowing humanity to devise Sentinels capable of adapting to any mutant power. After Shadowcat learns how to use her abilities to 'phase' someone into their past self, Xavier and Magneto decide to have her send someone back in time to the year 1973 to prevent Mystique from killing Trask, with Wolverine being selected as he is the only one who can survive the process due to his regenerative healing factor. Upon arriving in 1973, Wolverine locates the past versions of Xavier, Hank McCoy, and Magneto and convinces them to help him prevent their extinction. Although Magneto nearly jeopardizes the plan when he tries to kill Mystique and takes control of the Sentinels as part of his own plan to save the mutant race, Xavier is able to convince Mystique to spare Trask, resulting in her being publicly shown defending President Richard Nixon from Magneto. As a result, Mystique is hailed as a hero, the Sentinel program is scrapped, and Trask is arrested for selling his designs to foreign nations. The film ends with Wolverine waking up in a revised, idyllic future where the war with the Sentinels never happened and all of the X-Men are still alive.
