Captain Cold enlists the Fearians of Venus to help the Legion of Doom conquer Earth. They demand a climate like their own, so Captain Cold freezes the planet. When the Flash reverses it, rising steam heats the world. Black Manta burns an island, and Aquaman’s tidal wave spreads water and plant growth. Sinestro hurls comets, and Green Lantern shifts Earth’s orbit, raising temperatures further. With conditions set, the Fearians prepare to remake Earth into Venus II.
