Superman Robot X-3

Superman Robot X-3

"One of four original atom-powered Superman robots," X-3 is struck by a meteor while on a rescue mission in near-Earth orbit. Crash-landing on a distant planet, he is repaired by the mermaid scientist Mooki. After Mooki's death, X-3 creates a robot duplicate of her, and the two artificial creatures live as husband and wife, eventually creating a super-powered robot son, Nipper. In January 1962, Lois Lane observes the robot family using the "super radio-telescope" of Professor Burke and comes to the mistaken conclusion that Superman has a secret family. To convince her of his fidelity, the Man of Steel flies her to the tiny planet, where X-3 and his family relate their story (SGLL No. 30/1: "Superman's Secret Family" and "The Robot Paradise").
