Super Friends S01E15 - The Planet-Splitter

The Super Friends are alerted when a mysterious red light shines on diamonds and then vanishes. Our heroes discover that in the process, the diamonds are stolen and are replaced by imitations. Dr. LaBond, a misguided scientist and his "trusted" assistant Wilbur, are stealing diamonds to power the Planet Spitter, an invention which LaBond has perfected for the purpose of splitting a planet and using half of it to serve as a second moon with the hopes of providing Earth with more natural resources, but Wendy and Marvin point out that a second moon would cause terrible weather conditions on Earth. Dr. LaBond is certain the project will work, and has targeted the planet Signus Uno. However, the Super Friends have placed a micro dot homing signal on one of the stolen diamonds. The real thief turns out to be Wilbur, who wanted the diamonds so badly, that he made false reports to let Dr. LaBond think that his project would work when it was really a doomed failure all along. The center portion of this episode tells the origin of Superman, as narrated by Marvin, in hopes of dissuading Dr. LaBond and Wilbur from proceeding with their plans.
