X-MEN THE EARLY YEARS (1994) #9

Enter, the Avengers!, -Script by Stan Lee, pencils by Jack Kirby, inks by Chic Stone.

Xavier has tracked down Lucifer, the villain who cost him the use of his legs, but finds that he cannot attack as his foe's heartbeat is rigged to a giant thermal bomb. The X-Men arrive in Bavaria at Professor X's request and run across the Avengers who have also arrived, drawn by the evil Lucifer exhudes. In a classic hero vs. hero conflict, 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 clean up the current crisis on their own; Cyclops uses his eye beams to disable Lucifer's thermal bomb, ending the threat of one of Professor X's most personal foes.
