History of team is unknown.
- The X-Men occasionally guest-starred on Spider-Man and His Amazing Friends. Spider-Man, Iceman and Firestar were the three regular heroes. The X-Men first appeared on the Spider-Man and His Amazing Friends episode The Origin of Iceman. Appearing in this particular episode (in a flashback sequence only) are Professor X and the five original X-Men: Iceman, Cyclops, Marvel Girl, Angel, and Beast.
- The X-Men's next appearance Spider-Man and His Amazing Friends was in the episode A Firestar is Born. Making appearances in this particular episode are Professor X, Cyclops, Angel, Wolverine, Storm, and Juggernaut (plus Magneto in a cameo appearance).
- The X-Men would return the following season in the episode entitled The X-Men Adventure. Making appearances there were Professor X, Cyclops, Storm, Nightcrawler, Colossus, Sprite, and Thunderbird. The X-Men Adventure was meant to be a pilot for an X-Men cartoon, featuring the X-Men characters in the episode, plus Lady Lightning (animated version of Carol Danvers/Ms. Marvel) and Videoman as members. Needless to say, the cartoon never happened.
- This was the second time the X-Men were ever aired on television.
