G-Force: Guardians of Space (1986) is the second American animated television adaptation of the Japanese anime series Science Ninja Team Gatchaman (1972), following Sandy Frank Entertainment's initial 1978 effort Battle of the Planets and preceding ADV Films' 2005 attempt, known merely as Gatchaman. With G-Force, Sandy Frank Entertainment collaborated with Turner Broadcasting to create a newer, more faithful translation of Science Ninja Team Gatchaman for a new audience, and such a translation was made possible with the relaxed television standards of the 1980s, a luxury that the more Star Wars-themed Battle of the Planets did not enjoy.In the show, five brave teenagers — Ace Goodheart, Dirk Daring, Agatha June, Pee Wee and Hoot Owl battle the aliens Galactor and Computor for the fate of the planet Earth.
