Prince of Space

Wally (Tatsuo Umemiya) is the Prince of Space, a caped hero from another world who watches over Earth and the people on it. The dictator of the dark planet Krangkor, Ambassador Phantom (Joji Oka), comes down to steal a new rocket fuel formula from the kindly Dr. Macken (Ushio Akashi). Eijirō Wakabayashi made this as a pair of black-and-white featurettes from a television serial, and Wally takes on the theft in the middle of the fight.
