The Supermen, using their enhanced intellects, first repair Brainiac's "enlarging ray". They then create a means to bring all the fragments of Krypton together, creating a "New Krypton" (eliminating all existing kryptonite in the process), and successfully enlarge Kandor on its surface, freeing its citizens from their bottle prison. At the urging of Lori Lemaris, the Supermen create an underwater world for the citizens of Atlantis and arrange an interstellar voyage to transport them to their new home. The two Supermen go on to create an "anti-evil" ray which can cure criminal tendencies in anyone. They place the ray into satellites in orbit around the Earth, curing not only villains such as Lex Luthor and Mr. Mxyzptlk, but reforming Communists such as Nikita Khrushchev and Fidel Castro. The reformed Luthor goes on to invent a serum that cures all known diseases, which the Supermen put into the water supply. Supergirl then releases the Phantom Zone inmates, also reformed by the ray, and they immigrate to New Krypton in a spaceship provided by the Legion of Super-Heroes.
