Invasion of the Fearians
Captain Cold recruits the Fearians (inhabitants of Venus) to help the Legion of Doom take over the world and destroy the Super Friends. The Fearians say that the Legion has to make the environment suitable for Fearian life forms first, so Captain Cold freezes the world. When the Flash defrosts it, great quantities of steam make the temperature higher. Black Manta sets fire to an island in the Pacific Ocean. When Aquaman uses a great tidal wave to put out the flames, the water floods inland, making more plants grow. And finally, Sinestro sends six comets to Earth. When Green Lantern moves Earth out of its usual orbit to save it, the temperature rises even higher. The Fearians can now enter Earth to make it "Venus II".
