The following is an overview of the various villains featured in the long running Super Friends franchise.
The Legion of Doom is a fictional group of supervillains led by Lex Luthor that appeared in Challenge of the Superfriends, an animated series that starred superheroes from DC Comics.
In each episode they appeared in, the Legion of Doom enacted various plots against the Super Friends, only to be met with defeat by the end of the story. Often, however, they escaped capture through a last-minute plan.
The Hall of Doom was often positioned in a swamp outside Gotham City. It resembled Darth Vader's helmet. It could fly and be remote-controlled, and travel through time and another dimension. The Legion of Doom often used it to escape, for example rays from it could teleport the Legion. The group returned infrequently, notably in the Challenge of the Superfriends inspired Legends of the Superheroes.
Bizarro appears in the animated television series Challenge of the Superfriends (1978) voiced by William Callaway; Super Friends (1980 - 1982) and (1985 - 1986) voiced by Danny Dark. He is seen as a member of the Legion of Doom as an unambiguous villain. In one story he shows knowledge of how to construct a Growth Ray that makes someone 100 feet tall.
Bizarro World makes its first television appearance in Super Friends in the episodes "The Revenge of Bizarro" from 1980 and "Bizarowurld" from 1981. Bizarro World also appeared in the episode "The Bizarro Super Powers Team" from . Bizarro World is populated by countless imperfect duplicates of Supermen and Lois Lane, led by Bizarro #1.
Manta appeared on The All-New Super Friends Hour, where he was referred to simply as "Manta" and his suit color was now olive brown.
Black Manta also became a part of the Legion of Doom in Challenge of the Superfriends, where he was voiced by Ted Cassidy. He is never shown without his helmet here. In the episode "Doomsday", when he, Sinestro and Cheetah are abandoned by the rest of the Legion of Doom he takes control of a mental device to capture and punish the rest of the Legion.
Ted Cassidy voices Brainiac in Challenge of the Superfriends, and Stanley Ralph Ross in Super Friends including and .
On the ABC animated series Challenge of the Superfriends, Captain Cold is one of two Flash villains (along with Grodd) that appear as members of Lex Luthor's Legion of Doom. Dick Ryal provided the voice of Captain Cold. This version of Captain Cold was depicted as having pale blue skin.
The Priscilla Rich version of Cheetah appears in Challenge of the Superfriends and was played by Marlene Aragon vocally. She appeared earlier in the Super Friends comic as part of the Super Foes. In one of the Cheetah's most memorable episodes "The Secret Origins of the Super Friends", the Legion of Doom travel into the past to eliminate Superman, Green Lantern and Wonder Woman before they can become heroes. The villains arrive at Paradise Island, moments before Princess Diana competes in the Tournament she will win to become Wonder Woman. The Cheetah disguises herself as an Amazon to compete in the games and stop Diana, her athletic skills allowing her to get through most of the competition. As the tournament ends, only Diana and the Cheetah remain in contention and meet each other in a battle of stun rays to crown a winner. To assist her, the Cheetah uses "radar controlled" bracelets to deflect Diana's laser rays back at her, stunning the Amazon Princess. The Cheetah is hailed as the winner and is presented with the uniform and weapons of Wonder Woman. The blonde villainess, now wearing the uniform of the Amazon champion, gloats in her victory, "I've done it! Now I am Wonder Woman!". The Cheetah's victory causes Diana to be removed from the future timeline, thus eliminating Wonder Woman. However, the Legion of Doom's triumph is short-lived. The remaining Super Friends uncover the scheme and travel back in time to undo the damage. The Flash arrives at Paradise Island and uses his super-speed to deflect the rays meant to hit Diana and back at the Cheetah, stunning her. Diana is named the winner and goes on to become Wonder Woman.
Giganta appears in Challenge of the Superfriends voiced by Ruth Forman. She appears as a powerful member of the Legion of Doom. In the TV series, she has the ability to grow to giant size (with accompanying superhuman strength) simply by willing it (at the time, she did not yet possess this ability in the comics). She typically dresses in a leopard skin two-piece loincloth (presumably treating them so that they grow with her when she uses her powers to achieve her gigantic stature), wears large, bangle-like bracelets and anklets, and she is always barefoot (like her original appearances). Her muscular body is a side effect of her powers.
In the episode "History of Doom", it was revealed that Giganta was a normal woman who was horseriding when she witnessed Apache Chief using magic dust. The latter used it to grow larger so he could fight off a grizzly bear. Giganta stole the dust and used it on herself, gaining the ability to transform into a powerful, 50adj=midNaNadj=mid giantess. The dust not only gave the two size changing powers, but influences personality as well. Because Apache Chief was brave when using it he became one hundred times braver. Because Giganta had evil thoughts, it made her eviler.
Giganta later appeared in the Super Friends short episodes "Two Gleeks are Deadlier Than One" and "Revenge of Doom" again voiced by Ruth Forman. In "Two Gleeks Are Deadlier Than One", she and Gorilla Grodd capture Gleek and make an evil clone of him. In "Revenge of Doom", she was present when the Legion of Doom got back together but had no dialogue. Giganta teams with Grodd again to turn the residents of Gorilla City into humans and against the Super Friends in Super Friends #30 (March 1980).
On the ABC animated series Challenge of the Superfriends, Gorilla Grodd is one of two Flash villains (along with Captain Cold) that appear as members of Lex Luthor's Legion of Doom. In one episode, Grodd hatches a plot to take control of Gorilla City and use its citizens to conquer the world. He later appeared in the Super Friends short episodes "Revenge of Doom", and "Two Gleeks Are Deadlier Than One". Grodd teams with Giganta to turn the residents of Gorilla City into humans and against the Super Friends in Super Friends #30 (March 1980). This version of Grodd, though highly intelligent, never displays telepathic abilities. He was played by Stanley Ralph Ross.
Solomon Grundy appears in the 1970s animated series Challenge of the Superfriends as a member of Lex Luthor's Legion of Doom, voiced by Jimmy Weldon. In this cartoon series, Grundy speaks broken English with a southern accent. This version of the character was later used in a promotional spot for Cartoon Network, with Solomon Grundy declaring that "Solomon Grundy want pants too!" in response to Brainiac's request for pants.
This incarnation of Grundy is arguably one of the more "intelligent" versions of the character, as he is able to carry on a conversation and devise plans of his own.
See also: Lex Luthor in other media. Luthor was a recurring villain in Hanna-Barbera's Super Friends franchise that ran from the mid-1970s to the mid-1980s. He was voiced by Stan Jones. Of all the comic book villains to appear in the show, Lex Luthor appears in the most episodes, more than any other villain.
The episode "Superfriends: Rest In Peace" makes a reference to a former unseen member of the Legion, the only time such a reference has been made. This was Doctor Natas (Satan spelled backwards), the inventor of the Noxium crystal that had the power to destroy all of the Super Friends. The Super Friends knew of this crystal and tricked the Legion into thinking that it had killed all of them (using android doubles of the Super Friends). They anticipated the Legion throwing away the crystal when they no longer needed it. The crystal was retrieved by the Super Friends and launched into deep space. Natas' fate is unknown and the Legion apparently was unable to recreate the crystal.
The Riddler teamed with fellow villain Skyrocket in Super Friends #4 (April 1977). He went on to appear in Hanna-Barbera's Challenge of the Superfriends as a member of the Legion of Doom. He was voiced by Michael Bell. He made his only solo appearance in a Super Friends short episode "Around The World In 80 Riddles". He appears as a member of the Legion of Doom; he usually gives riddles to the Super Friends to delay them from meddling with the Legion's plans. In "Monolith of Evil", he uses a riddle to trick the Super Friends into getting a Monolith of enormous power guarded by a Lava Monster for the Legion after they fooled the Super Friends into abducting the United Nations and disguising the Monolith as the United Nations.
The Scarecrow appears in the 1978 Challenge of the Superfriends. He appears as a member of Lex Luthor's Legion of Doom voiced by Don Messick. His voice is raspy, fitting with his scare theme. Here he is shown to have control over a flock of crows, but no other powers. In one story, he beats Apache Chief in a contest to capture a two-headed snake by freeing a head Apache Chief had captured, then lassoing both heads.
In Super Friends #32 (May 1980), Scarecrow returns to induce phobias in the Super Friends such that they can no longer operate as crimefighters.
The Scarecrow later appeared in the Super Powers Team: Galactic Guardians episode "The Fear", voiced by Andre Stojka. In this episode he captures Batman, Robin and Wonder Woman; he then exposes them to his fear gas in what was the first animated rendition of Batman's origin, as he forces the Crusader to relive his memories of his parents' deaths.
Sinestro has been prominently featured in Challenge of the Superfriends (where he was part of the "Legion of Doom") voiced by Vic Perrin. He is shown to have the power to travel to the antimatter Universe without much trouble.
The Toyman is a recurring villain on the Challenge of the Superfriends television cartoon, voiced by Frank Welker. He appears as one of the members of Lex Luthor's Legion of Doom. The Toyman in the Super Friends series bears the likeness of Jack Nimball (as he is named in the comics). This version of the Toyman often dresses like a jester and wears a domino mask. In one episode he is shown to have control of a world of deadly toys within a black hole.

Darkseid appears in the cartoons, (1984) and (1985) voiced by Frank Welker.
Outside of the comic books, boom tubes have been seen on a number of occasions. They are first seen in the last two seasons of the Super Friends animated series, and on a number of occasions. Here, they are referred to as "Star Gates", and they are used by the natives of Apokolips.
DeSaad appeared in two of the 1980s incarnations of the Super Friends animated series: and , and was voiced by René Auberjonois.
Kalibak appeared in the last two incarnations of the original animated series, Super Friends, as his first televised appearance where he and Darkseid were voiced by Frank Welker. His appearance was not as brutish as later TV incarnations, more like the original Jack Kirby design for the character. He was almost always depicted as boastful, dull-witted and ineffectual against the heroes.
On the final season (1985–86) of the Super Friends, when Darkseid became a recurring villain, the Parademons followed, although the use of the word "demon" on television was often protested by parents' groups. Thus, Darkseid's minions were always referred to as "para-drones" on that show. Their vocalizations are provided by Frank Welker.
A villainous analogy to the Super Friends featuring major enemies to each of the heroic group's members.

Penguin went on to appear in , where he gains Superman's superpowers by accident when Felix Faust tries to get them for himself. Ironically, Batman is not featured in the episode. This version of the Penguin was voiced by Robert Morse. Penguin was intended to be part of the League of Evil in Battle of the Superheroes but he was licensed to Filmation and left out of what became Challenge of the Superfriends.
A brilliant scientist in botany, Pamela Isley turned to crime as Poison Ivy and fought Batman. Her junior partner was Honeysuckle. Ivy was intended to be part of the League of Evil in Battle of the Superheroes but she was licensed to Filmation and left out of what became Challenge of the Superfriends.

An earlier animated version of Bizarra was shown in an episode of the 1985 television series titled "The Bizarro Super Powers Team". In the episode, Bizarro decides that his world of Bizarros needs more heroes than just Bizarro Supermen. He takes a duplicator ray to Earth and makes Bizarro duplicates of Wonder Woman, Firestorm and Cyborg.

This universe's version of the Hall of Justice is called the Hall of Evil, and a demonic-looking face is on the outside of the building. The Super Enemies themselves appear almost identical to the Super Friends, although their version of Aquaman has an eyepatch, Batman's costume is red rather than blue, and Robin has a moustache.
Felix Faust attends a Halloween masquerade transforming wealthy guests into the monsters they're in costume (Bizarro, Solomon Grundy, Etrigan the Demon, Man-Bat, and Swamp Thing) in order to get their gems in Super Friends #28 (January 1980).

Faust was about to cast a spell to escape by transferring Superman's powers into himself, but Penguin seized the opportunity, stole the Superman powers, and broke out easily, leaving Faust behind. Faust later stripped Penguin of Superman's powers, and gained them himself after he had his spirits apprehend Penguin.
