With Professor Charles Xavier dead and Magneto taking over for the Marvel Comics superhero team, Marvel created the "Age of Apocalypse." In this alternate universe, members of The X-Men were not acting all like themselves because the timeline had changed so drastically. Because he was a time-traveler, the mutant known as Bishop was stranded in a dystopian future, searching for hope among the devastation left behind by the tyrannical ruler known as Apocalypse. With a single chance to reset things right, Bishop realizes desperate measures and ultimate sacrifices had to be made.
David Charles Haller, the mutant son of Charles Xavier and Gabrielle Haller, woke up from his coma with a devious plan. Calling himself Legion, David thought he could make Charles' dream for peace and unity come true if he murdered Erik Lehnsherr in the past. Just when David was about to deliver the fatal blow, Charles stepped in for his best friend and was struck dead. With his father dead, David was erased from the timestream and Erik was left alone to carry on Charles' dream by creating the X-Men.
