GR: Giant RoboEdit

GR: Giant Robo (GR ジャイアントロボ, GR: Jaianto Robo) is an animated TV series written by Chiaki Konaka (Serial Experiments Lain, The Big O) and directed by Masahiko Murata (Jinki:EXTEND, Mazinkaiser) and produced by SoftGarage. The TV series is a re-imagining of Mitsuteru Yokoyama's manga and was created to commemorate Giant Robo's 40th anniversary.

GR premiered January 19, 2007. The series finished its run on July 6 of the same year, totaling 13 episodes, with the possibility for two further seasons.[1] As of 2020, the series appears to have been cancelled.

The story takes place at the dawn of the 21st century, when Earth is overrun by giant robots. Daisaku Kusama encounters one of these monsters, the titular Giant Robo, in a ruin in Okinawa. Beckoned by forces he cannot understand, Daisaku is made to bond, body and spirit, with the ancient weapon and defend his homeland from the incoming evil.

A pilot for the show was made in 2005, which was a selection of scenes from the 1967 manga in animated form.[2] Due to a change in staff at SoftGarage, the idea of a faithful adaptation of Giant Robo was scrapped in favor for a modern world view, not unlike that of Neon Genesis Evangelion. The show also has elements of the Cthulhu Mythos in it, with the Giant Robo's originally being ancient machines built to fight off eldritch beings known only as "The Old Ones" that threatened the sanctity of the human race.
