In 1995, Marvel shocked the comics-reading world, canceling all its blockbuster X-titles and replacing them with new series in the transformed reality of the Age of Apocalypse! These tales, by some of the era's leading creators, introduced fans to radically new versions of the heroes they loved -- fighting for survival in a nightmarish dystopia where Charles Xavier is long dead! Professor X was killed twenty years in the past during a freak time-travel accident, and now the Darwinian conqueror Apocalypse rules with an iron fist -- ruthlessly enforcing his dictum that only the strong shall survive! In the long shadow of En Sabah Nur, hidden among a downtrodden humankind, are a group of ragtag freedom fighters led by Xavier's oldest friend: Magneto! They're amazing, they're astonishing -- but who are the X-Men?! Plus: What has become of iconic mutants Cyclops, Havok and Wolverine in this war-torn world? Collecting ASTONISHING X-MEN (1995) #1, FACTOR X #1, WEAPON X (1995) #1 and AMAZING X-MEN (1995) #1.
