The Fall of the Mutants Tie-In

"Masks"

Beast, Caliban, Cyclops, Iceman and Marvel Girl appear onboard the Ship: Apocalypse confronts them and subdues them all easily, then proceeds to reveal his backstory. He offers the mutants to join him, but when they refuse he orders Famine, Pestilence and War to attack the city. The three Horsemen are stopped by X-Factor, but can't fight back the fourth, Death, when his identity is revealed. As the Horsemen finally descend upon New York, only Caliban remains to free the others while Apocalypse is distracted.
