Battle of the Planets Battle of the Planets (1978) is an American adaptation of the Japanese anime series "Science Ninja Team Gatchaman" (1972). Of the 105 original "Gatchaman" episodes, 85 were used in the "Battle of the Planets" adaptation, produced by Sandy Frank Entertainment. The adaptation was generally faithful to the plot and character development of the original "Gatchaman" series, but significant additions and reductions were made in order to increase appeal to the North American television market of the late 1970s, as well as avoid controversy from parents; these included the removal of elements of graphic violence and profanity.
