More info: The X-Men are a fictional superhero team created by Marvel Comics that appear in comic books and various forms of media. The X-Men made their first ever animated appearance on the 1960s The Marvel Superheroes TV series with the original X-Men line-up (Angel, Beast, Cyclops, Jean Grey, and Iceman). Since Grantray-Lawrence Animation didn't have the rights to the Fantastic Four (their series was produced by Hanna-Barbera), they substituted them with the X-Men. The X-Men appeared in the Sub-Mariner episode "Dr. Doom's Day / The Doomed Allegiance / Tug of Death" (which was adapted from Fantastic Four Annual #3 (1965)). Interestingly enough, the X-Men were never referred to as the X-Men. They were, instead, referred to as Allies for Peace. The characters kept their original looks and individual names from the comics, though.
