Professor Xavier and the X-Men #10

Synopsis

Xavier has tracked down Lucifer, the villain who cost him the use of his legs, but finds that he cannot attack him as his heartbeat is rigged to a thermal bomb. The X-Men arrive at Professor X's request and run across the Avengers who have also arrived. The X-Men have to stop the Avengers from taking down Lucifer as the Avengers have no idea that if they defeat Lucifer, the world will be destroyed. After Xavier gives Lucifer a mind blast that renders him unconscious, he contacts his team for help and the Avengers agree to let the X-Men handle it. Cyclops disables Lucifer's thermal bomb.
