Today, it's "The Planet Splitter", from Super Friends. A mad scientist (John Stephenson, also the voice of Colonel Wilcox) uses a red light beam to steal valuable diamonds to power the titular machine. There's an interlude in the episode as Marvin (Frank Welker) reveals the origin of Superman. Casey Kasem (Robin) doubles as Jor-El.
Superman's origin would be retold in compressed form 5 years later on Challenge of the Super Friends, then in later series.
