# Space Emperor God Sigma

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. It ran for 50 episodes. It is also referred to as "God Sigma, Empire of Space" and "Space Combination God Sigma".

## Concept

Space Emperor God Sigma was created by Toei's Television Division, under the name "Saburo Yatsude" and animated by Academy Production (who subcontracted Greenbox). The series was produced by Toei Company, and not by its own animation studio Toei Animation; Yoshinobu Nishizaki's Academy Productions provided the animation services. Toei Agency handled the advertising for the show, and its main sponsor was Popy (now Bandai's Boy's Toys Division).
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. This show is a similar situation to the Robot Romance Trilogy, where Toei produced each show, but the animation was done by Nippon Sunrise.

## Story

The story is set in the year 2050 AD, and mankind has been steadily advancing its space technology. However, the planet is suddenly set upon by a mysterious enemy: the forces of Eldar, who came from 250 years in the future. In their time, 2300 AD, their planet Eldar was invaded by Earth, and soundly defeated by Earth's Trinity Energy, a mysterious energy used in their weaponry that possesses power many times that of a hydrogen bomb. The Eldar people's objective is to steal this Trinity Energy before it can be used against them.
The Eldar forces begin by taking over Jupiter's moon Io, one of the places humanity has immigrated to by then. After that, they begin to attack Trinity City with their legions of Cosmosauruses in order to steal the Trinity Energy. 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.

## Mecha
### God Sigma

The completed giant robot formed when the Kuuraioh, Kaimeioh, and Rikushin'oh combine with the Big-Wing.
With the command "Sigma Formation", the three robots form a triangle, and when they shout "Trinity Charge", the Big-Wing flies to them and combines. Two separate combination scenes exist in the anime - one during the beginning, and one from the middle onwards.
Its total height was originally stated to be 265 meters tall, but since this would cause difficulties for the actual animation, it was changed to 66 meters. It weighs 1200 tons, and its power source is Trinity Energy. It possesses the ability to cruise from Earth to Jupiter and back. It can be controlled by the main pilot, Toshiya, but without the other two component robots' generators to supplement his own, it's not as powerful.
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.

## Theme songs

Opening theme: "Ganbare! Uchuu no Senshi" (Do Your Best, Space Warrior!)
* Vocals: Isao Sasaki, Koroogi '73, Columbia Yurikago-kai
* Lyrics: Saburo Yatsude
* Composition: Asei Kobayashi
* Arrangement: Masahisa Takeichi
Ending theme: "Red Blue Yellow"
* Vocals: Kumiko Kaori, Koroogi '73, Columbia Yurikago-kai
* Lyrics: Saburo Yatsude
* Composition: Asei Kobayashi
* Arrangement: Masahisa Takeichi
The ending theme, "Red Blue Yellow", consists of the planets in the Solar System in order. At the time of the show's broadcast, Pluto was actually inside the orbit of Neptune. This was not reflected in the animation, the reason being that the show itself is set in the year 2050. Also, the rings of Jupiter had just been discovered the year before, so in the ending animation, Jupiter is depicted with rings. However, in contrast to the actual rings of Jupiter, which are too thin to see a shadow cast on the planet, the picture of Jupiter in the ending sequence does have the shadow of rings on it.

## Media

The series was telecast in Italy, simply titled God Sigma.
God Sigma toys were released under the premier Godaikin toy label in Japan and Hong Kong in the 1980s.
In March 2011, Pony Canyon released a complete DVD box set, which only had a limited production run.
In July 2024, Discotek Media released a Blu-ray box set. It is the first English release of the series.

## Appearances in other works

Space Emperor God Sigma appears in various games by Banpresto (currently Bandai Namco Games). Its first appearance was in a 1992 Famicom game called Shuffle Fight. 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. In the same game, a robot from Gravion called God Σ Gravion appears, triggering a conversation between the characters of each series. God Sigma also appears in the game's two-part sequel, 2nd Super Robot Wars Z: Hakai-hen and Saisei-hen.
