Captain Cold recruits the Fearians (inhibitants 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 and when Flash defrosts it, great quantities of steam making the temperature higher, Black Manta sets fire to an island and when Aquaman uses a great tidal wive to put out the flames, the water floods inlands, making more plants grow and finally, Sinestro sends comets to Earth and when Green Lantern moves the Earth out of its usual orbit place to save it, the temperature rises even higher. The Fearians can now enter Earth to make it "Venus II".
