Charles Xavier is dead — killed in the past during a time-travel accident — and without his dream, the world has become a nightmare! Apocalypse rules with an iron fist, ruthlessly enforcing his “survival of the fittest” creed — but hidden among a downtrodden humankind are Magneto’s ragtag freedom fighters: the X-Men! When Bishop, last survivor of the true Marvel Universe, explains how the world went wrong, these embittered mutants must risk everything — and undertake a dangerous and complex quest — to put things right!
