An alien, the being known as Lucifer was born on the planet Quistalium, in the Quistraa star system in the Milky Way Galaxy, who had invaded many worlds. He first came to Earth as an advance agent for the invasion of Earth by the Arcane (also known as the Quists), and succeeded in placing some humans under hypnotic control, allowing him to take control of a small area. This invasion, however, was foiled by the young Charles Xavier (later Professor X, leader of the X-Men). In retaliation, Lucifer dropped an enormous stone block on Xavier, leaving his legs crippled so that he would need a wheelchair. Lucifer made several later attempts to conquer Earth, all foiled by the X-Men or other heroes.
