Because of a rise of anti-mutant activity in Genosha, Professor Xavier uses Cerebro to scan the island nation and discovers Apocalypse's presence there. Genosha's government is apparently using Apocalypse to bring their mutant population under control. However, Xavier suspects Apocalypse to follow his own plans and sends five X-Men, Cyclops, Wolverine, Psylocke, Beast and Gambit, to investigate.
