Legion (David Haller), an Omega Level psionic mutant on Earth and son of Professor Charles Xavier and Israeli diplomat Gabrielle Haller, travels back in time with the intention of killing Magneto, Xavier's former best friend and current archnemesis. When David is on the verge of ending Magneto's life, Xavier places himself between the two, and Legion inadvertently kills Xavier instead. Due to a "Grandfather paradox", Legion then ceases to exist as Xavier now died before Legion was even fathered.
Because of Xavier's sacrifice, Magneto comes to believe in his late friend's dream of peaceful coexistence between humans and mutants. Apocalypse, an immortal mutant who has been alive for centuries, was monitoring the fight. In this reality, he chooses this moment as the perfect time to begin his "survival of the fittest" genetic war, which doesn't happen in the regular Marvel Universe until ten years later.
In this timeline, Magneto assembles the X-Men after Apocalypse establishes himself as a major power. Apocalypse comes to rule all of North America (the Statue of Liberty is replaced by a gigantic statue of his visage), and initiates a worldwide genocidal campaign of "cullings" in which millions of humans die. The few that survive live in parts of Europe and Africa which were not devastated by nuclear weapons. Fleets of Sentinels are their only defense.
