The Legion of Doom is a group of supervillains that originated in Challenge of the Super Friends, an animated series from Hanna-Barbera based on DC Comics' Justice League. The Legion of Doom has since been incorporated into the main DC Universe, appearing in comics, as well as further animated and live-action adaptations.

In each episode of Challenge of the Super Friends that they appeared, the Legion of Doom would enact a plot against the Super Friends and a plot to take over the world only to be met with defeat by the end of the story. In some episodes, they would escape capture through a last-minute escape plan often contrived by Luthor. Other times, the Legion of Doom would end up apprehended.

The episode "History of Doom" showed that Lex Luthor assembled 12 supervillains in order to form the most powerful and sinister group the world has ever seen.

When the Challenge of the Super Friends season was originally conceived, it was named Battle of the Superheroes and featured the introduction of Captain Marvel to the Super Friends. The group that challenged the heroes was to be called the "League of Evil", led by Captain Marvel's nemesis Doctor Sivana. However, Filmation was producing Shazam! and The New Adventures of Batman which prevented the use of characters such as Mister Atom, King Kull, Beautia Sivana, Joker, Penguin, Mr. Freeze, and Catwoman. Early conceptual art drawn by Alex Toth also included Heat Wave, Poison Ivy, and Abra Kadabra.
