In the Earth-1A universe, a similar universe to Earth-One, exists the Legion of Doom, an organized body of self-proposed Supervillains. Although they never seem to get the upper hand on their nemeses, the SuperFriends, they nevertheless quest for evil and the destruction of all that is good.
In response to the joining together of the the SuperFriends, these villains felt that they needed to combine forces to keep from being defeated.
|“||Banded together from remote galaxies, thirteen of the most sinister villains of all time - the Legion of Doom!||”|
— SuperFriends, Narrator
In each episode that they appeared, the Legion of Doom would enact various plots against the Super Friends, only to be met with defeat by the end of the story. Often, however, they would escape capture through a last-minute escape plan.
The Legion of Doom was always a mismatch against the likes of the SuperFriends. Indeed, by sheer numbers the Legion outdo the Friends with two extra members; however, when you consider that the Riddler is among the surplus members, the odds are still not in their favor.
This elite group of villains was formed by Lex Luthor, yet, he certainly did not maintain absolute leadership over the rest of the group. In-fighting, deceit, and suspicion are rampant throughout each and every Legion appearance.
Although the lineup is meant to be a collection of the best and brightest among super criminals, more than likely members of the production team tried to balance a lineup with at least one foe for every SuperFriends team member, such as Black Manta vs. Aquaman, and Captain Cold vs. the Flash.
|Lex Luthor||Brainiac||Gorilla Grodd||Black Manta||Cheetah||Sinestro|
|Captain Cold||Scarecrow||Toyman||Solomon Grundy||The Riddler||Giganta||Bizarro|
Another member of the group, but it's not certain which incarnation of the group he was in, was Doctor Nataz. He invented the noxium crystal, which was deadly to every member of the Superfriends, as it contained trace amounts of their weaknesses in it.
The Hall of Doom was mobile, lowered below or raised above the swamp water's surface, and often flown through the air via rockets if needed, even remotely controlled. It also had laser defense weapons and at times was altered to time travel to the past or future.
