X-Men: The Complete Age of Apocalypse Epic #1

This first volume of the Complete Age of Apocalypse Epic collects the opening chapters of Marvel's sprawling 1995-1996 alternate-reality saga, where Charles Xavier's son Legion kills his father in the past, allowing Apocalypse to conquer the world. Key issues include X-Men Alpha, X-Men: Age of Apocalypse #1-4, and the start of several tie-in miniseries, featuring characters like Sabretooth, Wild Child, and Colossus in radically altered roles. It sets the stage for a desperate war between Apocalypse's forces and the remaining X-Men of this dark timeline.
