The Legion of Doom is a group of supervillains who originated in Challenge of the Superfriends, 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 American comic books, as well as further animated and live-action adaptations, and video games.
In each episode of Challenge of the Superfriends 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 (or portions of it) would end up apprehended.
The episode "History of Doom" showed that Lex Luthor assembled 13 supervillains in order to form the most powerful and sinister group the world had ever seen.
When the Challenge of the Superfriends 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, The Joker, The Penguin, Mr. Freeze, and Catwoman. Early conceptual art drawn by Alex Toth also included Heat Wave, Poison Ivy, and Abra Kadabra.
The Legion of Doom's headquarters was the Hall of Doom which was located in Slaughter Swamp (just outside Gotham City). The facility, which resembles Black Manta's helmet, could be lowered or raised above the swamp water's surface. It could fly or enter space using rockets. The Hall of Doom's mobility could be controlled through remote control helping the Legion to escape on several occasions. Its defenses included laser weapons and the ability to time travel.
In "Doomsday" after Sinestro, Black Manta and Cheetah are abandoned by the rest of the Legion after they take control of a mental device, they use it to create another Hall of Doom, which attacks the original one and enables the Legion to be captured.
In "History of Doom", it is revealed that the Hall of Doom was placed in a swamp as a compromise between Black Manta, Captain Cold, and Gorilla Grodd, who respectively wanted it to be placed in the ocean, underneath the polar ice caps, and in a jungle.
There were thirteen members of the Legion of Doom:
Members of the Legion of Doom made some appearances in the Super Friends spin-off comic title based on the TV series:

One of the nicest bits in "Alive!" was consciously making Luthor's team the villains that the audience had seen most of, more or less, and cared about. Which was good, since we were hopefully making the audience worry about and root for Luthor's group. This also let us come as close as we could to the classic 13 LOD villains. Grodd was now the enemy and was dead; Captain Cold wasn't around; Devil Ray and Grundy were gone and we couldn't use Scarecrow or Riddler, so we were left with: Luthor (who kind of counted as Brainiac), Bizarro, Giganta, Cheetah, Sinestro and Toyman. And no, I couldn't keep all 13 straight two years later without referring to my script and Wikipedia.
