Prince Planet (1965)

Prince Planet is the English-language title given to one of the earliest Japanese anime TV series, Planet Boy Papi, when it was transmitted on American television in the United States in the mid-1960s. A 52-episode monochrome anime series, it tells the story of a member of the Universal Peace Corps, originally from the planet Radion, coming to Earth on a mission to determine if this world meets standards for membership in the Galactic Union of Worlds and assist its inhabitants during his stay. While on his mission, Prince Planet adopts the identity of an Earth boy named Bobby and gains comrades who work together alongside him fighting forces of evil, both alien and terrestrial.
