Science Ninja Team Gatchaman

Science Ninja Team Gatchaman (科学忍者隊ガッチャマン, Kagaku Ninja-tai Gatchaman, lit. Science Ninja Squad Gatchaman), also simply titled as Gatchaman is a 1972 Japanese anime television series produced by Tatsunoko Production which aired on Fuji Television and its affiliates from October 1, 1972 to September 29, 1974 for 105 episodes. The series centers on a five-member superhero ninja team known as the Gatchaman as they save the world from the mysterious secret organization known as the Galactor.

Following its run on Fuji TV, Tatsunoko would license the show to Sandy Frank Syndication, owned by producer Sandy Frank, which would create an adaptation entitled Battle of the Planets, which aired in the US in syndication during 1978. The original series was dubbed into English twice with the 1986 dub by King Features Entertainment and Turner Broadcasting System, titled G-Force: Guardians of Space and the 2005 ADV Films uncut release, both under license from Sandy Frank. Tatsunoko also uses the official translation Science Commando Gatchaman in related products and media.

The original Gatchaman series was followed by an animated film and two direct sequel series, Gatchaman II (1978) and Gatchaman Fighter (1979). During the 1990s, episodes from both series were dubbed into English by Saban Entertainment as Eagle Riders.

In the years since, the franchise has spawned many different productions, some that were left unproduced or evolved significantly from its development. This includes a 1994 original animated video remake, an unproduced 1998 television remake, a cancelled 2011 animated film reboot by Imagi Animation Studios, a 2013 Japanese live-action film reboot by Nikkatsu Studios, a comic book series by Mad Cave Studios, various spinoffs, re-imaginings, and merchandise.
