Obsession

S3, E11: Archangel has become obsessed with destroying Apocalypse, who he blames for ruining his life. A sympathetic Rogue joins his reckless, Ahab-like quest, against the warnings of the other X-Men, who have their own, more indirect plan to stop Apocalypse. In the end, the X-Men have Apocalypse in their grasp, only to have their plan ruined by Archangel's unthinking vengefulness.
