James Arthur Madrox, also called the Multiple Man, is a fictional character appearing in American comic books published by Marvel Comics. Created by writer/editor Len Wein, he first appeared in Giant-Size Fantastic Four #4 (February 1975). A mutant with the ability to create instant duplicates of himself, Madrox was mainly a minor or supporting character until his appearance in the 1987 miniseries Fallen Angels. The character underwent greater development under writer Peter David through his appearance in David's run of the monthly series X-Factor (vol. 1) in the 1990s, and in David's second and ongoing run of the title (vol. 3) in the 2000s. The character has appeared in multiple television, film and video game adaptations, most notably in the 2006 film X-Men: The Last Stand, in which he was portrayed by Eric Dane.
