The Conquest of Superman! – With Superman off planet, it’s up to Lex Luthor’s great scientific brain to save a crashing plane loaded with an H-Bomb. He does, and manages a jail break in the process. His next target: to publicly and utterly defeat Superman in the middle of a crime. “The Battle of the Super-Pets” – Krypto helps Supergirl out of a bind, and Streaky gets jealous. The pair start to duel in a series of contests, which take place on a highly unusual planetoid.
