Doomsday

The Legion of Doom launch an attack on an aircraft earlier. Green Lantern, Aquaman, and Apache Chief battle their Legion counterparts Sinestro, Black Manta, and Giganta and capture them when the other Legion of Doomers leave their comrades to their fate. Sinestro manages to escape from the Hall of Justice with the others and substitute anti-matter robots. When Superman touches them he is briefly transferred to the anti-matter universe of Qward and fights an anti-universe Krypton knight. Meanwhile, the three renegades steal a matter-transmutation device from the Flash and Black Vulcan. They 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 Super Friends but Superman manages to get to the transmutation device and stop it, leaving the Legion to be captured once more.
