Science Ninja Team Gatchaman (科学忍者隊ガッチャマン Kagaku Ninjatai Gatchaman?) is a five-member superhero team composed of the main characters of several anime created by Tatsuo Yoshida, originally produced in Japan by Tatsunoko Productions and later adapted into several English-language versions. The team is also known as Gatchaman.
The original series, produced in 1972, was eponymously entitled Kagaku Ninja Tai Gatchaman and is best known in the English-speaking world as the adaptation entitled Battle of the Planets (1978). The series had additional English adaptations with G-Force: Guardians of Space (1986) and ADV Films’ uncut 2005 release. Tatsunoko also uses the official translation Science Commando Gatchaman in related products and media.
The original Kagaku Ninja Tai Gatchaman series was followed by an animated film and two sequel series, Gatchaman II (1978) and Gatchaman Fighter (1979). During the 1990s, episodes from both series were dubbed into English by Saban as Eagle Riders. In 1994, the original series was remade as a condensed original video animation series.
A second feature-film version of Gatchaman was in production by Imagi Animation Studios, directed by Ben Gluck for a 2012 release, but was canceled as a result of the studio’s financial problems. A live-action film was developed by Nikkatsu Studios and released in 2013.
