The storyline starts with Legion (David Haller), a psychotic mutant who traveled back in time to kill Magneto before he can commit various crimes against humanity. Legion accidentally kills Professor Charles Xavier, his father, leading to a major change in the timeline. The death of Professor Xavier leads Apocalypse to attack 10 years sooner than he did in the original timeline, taking control of Earth and altering everything that happened from that point forward. Apocalypse is opposed by several factions of mutant resistance, including a group led by Magneto. The group manages to send the mutant Bishop back in time to prevent the murder of Professor Xavier, undoing the entire timeline.
