Space Emperor God Sigma (宇宙大帝ゴッドシグマ, Uchū Taitei Goddo Shiguma) is a mecha anime television series aired from 1980 to 1981.

Space Emperor God Sigma was created by Toei's Television Division, under the name "Saburo Yatsude" and produced by Academy Production (who subcontracted Greenbox).

This anime was the last that Takashi Ijima would work on; he had been part of Toei's TV division's projects since Chōdenji Robo Combattler V, which aired in 1976.

Joined by Katsuhiko Taguchi, the chief director, the two created an anime that lasted for four full seasons, which was rare at the time of its broadcast.

Toshiya and his friends use God Sigma to protect the planet and the Trinity Energy, and the battle evolves into a long war to retake Io.

Voiced by: Yoshito Yasuhara Assistant to Dr. Kazami, the head scientist and researcher at Trinity City, he is one of the three pilots of God Sigma.

Voiced by: Noriko Ohara, Hiromi Tsuru (in Super Robot Wars Z) The supreme commander of the Eldar forces sent to Earth to steal the Trinity Energy.

In the final episode, it and the giant mecha Gargos destroy each other, but it is repaired after the war and revamped to be a single-pilot machine, and Toshiya sets off with it by himself.

Its second was in the 2008 PS2 game Super Robot Wars Z, but by this time, Toshiya's voice actor Tomiyama Kei had died, so the role was given to Tomokazu Seki instead.
