The Legion of Doom launch an attack on an aircraft earlier. Green Lantern, Aquaman, and Wonder Woman battle their Legion counterparts Sinestro, Black Manta, and Cheetah and capture them when the other Legion members abandon them. Sinestro manages to escape from the Hall of Justice with the others, replacing themselves with duplicate anti-matter robots. When Superman touches them, he's briefly transferred to the anti-matter universe of Qward and fights an anti-universe Krypton knight. Meanwhile, the three renegades steal a mental-matter ray that's being guarded by the Flash and Apache Chief. They later use the device to gain revenge on their Legion of Doom comrades by transmitting them into bowling pins and billard balls before deciding things are even. With the aid of the device, they manage to defeat most of the SuperFriends but Superman manages to get to the transmutation device and stop it, leaving the Legion to be captured once more.
