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.

They want to capture it and use it against the Legion. Written by
