Brainiac devises an evil scheme to help the Legion of Doom rid themselves of the SuperFriends once and for all. As Wonder Woman, Hawkman and Black Vulcan repair one of NASA's orbiting space stations, Brainiac uses his cloaking device to make the Earth seem to disappear. Then Toyman leads them deep into space, where they fall through a black hole and get trapped on Toyman's planet of deadly toys, which include a giant pinball machine and an enormous wind-up baby doll. Meanwhile, the Riddler sends the rest of the SuperFriends on a wild goose chase looking for their three missing team members. They are sent to an abandoned nickel mine in the Grand Canyon; the hottest star in the Orion constellation (which is a planet of Amazon women); and finally to the black hole. While they're away, the Legion of Doom blackmails the world for all its money.
