Iceman gets too frozen, the Beast gets too bestial, and the Angel gets a really sharp new set of wings as the original X-Men face mutant-haters and hate-filled mutants who agree on one thing: They want X-Factor dead! Apocalypse first gathers his horrendous Horsemen, and Caliban makes the transition from tracker to Hellbound! Infectia, Orphan-Maker and the Alliance of Evil! Plus: For fans of the current X-Factor, witness Quicksilver's earlier descent into dementia and the first appearance of Rictor! Featuring Thor, Freedom Force and more!
