Lex Luthor forms a criminal gang called "The Legion of Doom" and uses a dream-machine to make the Super Friends commit crimes. When the Super Friends are forced to turn themselves into police headquarters, the guards reveal themselves to be Bizarro and Cheetah who send the Super Friends to the sun while the Legion of Doom uses the Super Friends' own Justice League satellite with Luthor's mutation device to turn women into Cheetah clones and men into Bizarro clones and commit profitable robberies. The Super Friends return to Earth to reverse the damage done and retake The Hall of Justice.
