nniJennifer Lawrence portrays a younger Mystique in the 2011 prequel X-Men: First Class. Morgan Lily briefly plays Mystique as a child while Rebecca Romijn makes a cameo as a transformation Mystique takes to seduce Magneto. She is raised as Charles Xavier's foster sister, and helps found the X-Men, but eventually defects to Magneto as she is dissatisfied with Xavier's constant attempts to ask her to hide where Magneto encouraged her not to fear her true appearance. Lawrence reprises her role as Mystique in the 2014 film X-Men: Days of Future Past. In the film, it was her assassination of Bolivar Trask that leads to his martyrdom, resulting in the fruition of his Sentinel program. Mystique was subsequently captured and experimented upon, leading to the Sentinels' unstoppable shapeshifting abilities and a dystopian future. The film revolves around Wolverine's attempts to stop her assassination of Trask and avert the dark future after he is sent back in time by Kitty Pryde projecting him into his younger self. The group stops Mystique's attempt to kill Trask, but the altercation exposes mutants to the world for the first time earlier than in the previous timeline, prompting President Nixon to approve the Sentinel program while Trask studies a blood sample Mystique left behind during the attack. While Trask Industries ships the Sentinels to Washington, D.C. for their national presentation, Magneto secretly surrounds the Sentinels in steel, allowing him to control them. He subsequently commandeers the Sentinels to attack the crowd and hold off Wolverine, Xavier, and McCoy, but before he can kill what he believes to be Nixon (really a disguised Mystique), McCoy suppresses his mutation with a serum causing a Sentinel to turn on Magneto. Magneto quickly disables it, but the distraction allows Mystique to shoot him with a plastic gun, wounding him and releasing his control of the Sentinels. After Xavier convinces Mystique to let Trask live, the world sees that a mutant saved the President and the Sentinel program is shut down. Trask is arrested for selling military secrets to foreign powers, erasing the dystopian future seen earlier in the film. Mystique remains a rogue agent, disguising herself as William Stryker to retrieve Wolverine from the Potomac River. Lawrence reprise her role as Mystique in X-Men: Apocalypse. The film is set in the 1980s, with Mystique now the 'public face' of the idea of heroic mutants, and not aligned with Magneto as she did in the original timeline after the events of the last film. Despite being idolized by other mutants as a hero, she rejects the notion while focusing simply on getting the oppressed to safety. Younger mutants like Ororo Munroe, Scott Summers, and Jean Grey see her as an inspiration, and some have begun trying to use their powers for heroics or vigilantism based on her examples. After she sees a news report about the death of Magneto's family while she is trying to help Nightcrawler, she has him take her back to Xavier's mansion so that Xavier can help her find Erik. In the process, she unintentionally alerts the powerful new foe Apocalypse to their existence, prompting him to abduct Xavier.
