Overview
The Superman Revenge Squad is the name of two fictional organizations in the DC Comics universe. As their name suggests, it is a group of Superman villains who banded together to defeat the Man of Steel.
Pre-Crisis on Infinite Earths
In Pre-Crisis continuity, the Squad originated as the Superboy Revenge Squad, debuting in Superboy #94 (January 1962); the Superman Revenge Squad subsequently appeared in Action Comics #286 (March 1962). Both Squads are composed of aliens from the planet Wexr II, whom Superboy had prevented from achieving galactic conquest. The Squad later grows to include members from other planets, all of whom are sworn enemies of Superman.
Many of the Squad's plans to destroy Superman use psychological warfare, including red kryptonite-induced nightmares, hypnotising Superman into committing destructive acts, and tricking Superman into revealing his secret identity. They transferred the intelligence of a Superman robot into a super-powered body, making him Wonder Man, and hoping he would destroy Superman with some kryptonite that he was given and to which he was invulnerable. He later realized their plot and, with Superman, threw the ship with such force it would take years for the two members to break free, but Wonder Man then told Superman that his body would soon die. Once they lured Superman into following them to 1,000,000 AD, where he lost his powers and was trapped on the Earth, due to the Sun having turned red by then. He used a miniature Kandorian rocket left in his Fortress of Solitude, after shrinking himself with red kryptonite, to travel back to his own time. They appeared briefly in the first Superman Red/Superman Blue (July 1963) storyline, they were about to attack the Earth after teaming up with Brainiac, but, in that moment, the anti-evil rays Superman developed struck them and they reformed.
In their earliest appearances the Squad members appeared hooded in order to keep their identities a secret. Later versions of the Squad wore modified versions of Superman's costume, with the S-shield made of kryptonite and their heads shaved bald in tribute to Lex Luthor.
