The '90s was a decade of pure nirvana for comic book fans looking for their favorite characters to hit the small screen, and X-Men: The Animated Series helped lead the revolution by introducing a generation of kids (and some adults) to the world of Marvel’s Merry Mutants. Adapting storylines straight from the comics, X-Men was famous for delving head-first into the complicated mythology of the characters without ever confusing fans by getting bogged down in its own excess.

Each episode touted a list of cameos and guest appearances by some of the most popular citizens of the Marvel Universe, but Wolverine, Cyclops, and the other X-Men were always the main focus of the show. With slick action scenes and deep stories that often took an entire season to unfold, X-Men: The Animated Series is still the best Marvel cartoon to ever hit the air.
