- "Banded together from remote galaxies are thirteen of the most sinister villains of all time - the Legion of Doom! Dedicated to a single objective - the conquest of the universe!"
The Legion of Doom are a fictional supervillain team featured in the Super Friends series of animated projects. They are based on previously existing comic book characters featured in titles published by DC Comics, though they usually worked alone and were not known as the Legion of Doom. The group served as the primary antagonists of the 1978 Hanna-Barbera Productions series, Challenge of the Super Friends. They first appeared in the premiere episode of the show, "Wanted: The Super Friends", and have appeared (in whole or in part) in each episode of the series.
