Apocalypse

Few Marvel villains have cast as long a shadow as Apocalypse, who burst onto the scene in X-Factor #27 in 1988 — a Copper Age debut courtesy of the formidable creative team of Louise Simonson and Walter Simonson. Over roughly two decades of publication, this imposing figure carved out a place among Marvel's most formidable threats, sharing the page with heavy-hitters like Cyclops, Iceman, and Hank McCoy. His presence across both X-Factor and the Ultimate X-Men line speaks to a villain whose menace translated across continuities, and any collector with an eye for era-defining antagonists will find Apocalypse well worth tracking down.
