Chap. 2: "The Robot Paradise"

Synopsis:
Lois Lane visits the lab of Professor Burke, an astronomer who has invented a powerful telescope. Viewing distant worlds, Lois sees Superman with a mermaid wife and son. When he returns to Earth, Lois is upset that he did not tell her about his secret family.

Superman investigates and brings Lois to the small planet. They soon meet the mermaids and another Superman who turns out to be a robot. The robot explains that he is a damaged Superman robot X-3 which crashed on this world. A dying mermaid woman, Mooki repaired him partially, but he was stranded on the planet. When Mooki died, X-3 built a robot Mooki and a son Nipper and lived as a family. Superman and Lois wish them well and return to Earth.
