Lucifer

Lucifer is an alien villain from the early Marvel Universe, responsible for the accident that left Charles Xavier paralyzed and wheelchair-bound. He clashed with the original X-Men, making him a significant figure in mutant history from his very first appearance.

Born in the pages of The X-Men #9 in 1965, this Marvel villain stepped onto the Silver Age stage courtesy of the legendary duo Stan Lee and Jack Kirby — and that debut alone makes him a collector's prize, with the issue recognized as a key. Lucifer carved out his corner of the early Marvel Universe rubbing up against some of the most iconic mutants in comics history: Cyclops, Iceman, Charles Xavier, and the young Scott Summers and Bobby Drake were all there to witness his arrival. Though his catalog footprint is compact, his longevity is quietly remarkable — a character introduced sixty years ago who has never fully faded from Marvel's pages. For fans of Kirby's boundless Silver Age imagination and the formative era of the X-Men, Lucifer is one of those fascinating early antagonists worth tracking down.
