And to do it, he plans to make Xavier's dream a reality — by traveling back in time to kill its greatest obstacle, Magneto! The X-Men scramble to stop him from altering history — but, lost in the past, can they thwart Legion's misguided mission before the entire Marvel Universe is wiped away? Plus: Mystique seeks revenge against Legion, even as her shocking connection to Nightcrawler is revealed!
