Professor X finally catches up with his nemesis Lucifer. However, Lucifer has rigged up his doomsday device to his heartbeat. Meanwhile, the X-Men arrive in Eastern Europe and must stop the Avengers, who have been tracking Lucifer's energy emissions, from reaching Lucifer. The X-Men keep the Avengers busy long enough for Professor X to subdue Lucifer without affecting his heartbeat. With Cyclops' help, Professor X defuses Lucifer's doomsday device.
