15. Bishop (Marvel Entertainment)
First Appearance: Uncanny X-Men #282 (1991)
Creators: John Byrne, Jim Lee, Whilce Portacio
Bishop came into the world during a time when the X-Men franchise was introducing new characters nearly every month, but something about this time-traveling antihero resonated with fans. Lucas Bishop came to the past to join the X-Men in an attempt to defeat Trevor Fitzroy, but he decided to stay in the present, acting as a part of the main team of mutants, as well as part of an FBI program to stop mutant-related crimes in District X.
Whereas most characters introduced in the ‘90s were little more than overblown action stars, Bishop has demonstrated real complexity over the years. His relationship with Cable and Hope during the Messiah Complex storyline made for captivating reading. Plus, dude sported a mullet like nobody’s business.
