The Legion of Doom attacks America's greatest nuclear powered Aircraft Carrier, The Dauntless. The goal is to capture the ship and ransom it and the crew for millions. The Superfriends foil the attempt and Sinestro, Cheetah, and Black Manta are captured. The Legion leaves without them and the three swear revenge against them. While in the Justice League detention cells they overhear of the Army's newest weapon... a Mental Matter Ray which can alter reality and reform it into any shape. They want to capture it and use it against the Legion.
