Groizer X (グロイザーX Guroizā X?) is an anime series aired from 1976 to 1977. There were 36 episodes. It is also referred to as Gloyzer X and Gloizer X.


The Gaira aliens, hidden in the Arctic, plan to conquer Earth. Captured and forced to work for the aliens, Dr. Yan creates the ultimate weapon, a transformable aerial robot called Gloizer X. Groizer X was 100 meters tall and weighed 1200 tons. Entrusted to his daughter Rita, Gloizer X escapes the clutches of the Gaira and lands in Japan, where pilot Joe Kaisaka meets a wounded Rita. Taking up the controls of Gloizer X, Jo and Rita fight against the Gaira invasion.


The anime was created by Go Nagai as a side project during the time he was busy with the various Mazinger series, Groizer X nevertheless managed to be converted into a TV series. The robot transforms into a jet, while the show included intense battle sequences and aerial combat, it remained a secondary super robot series.

The original Groizer X toyline are one of the very few Super Robot toys produced by Nakajima Manufacturing Company instead of the industry dominant Popy Pleasure[1].

Yamato then did a GN-U Groizer X figure released in 2007. A Manga version of the figure was produced, only painted in green.

Outside Japan

While not being a great success in Japan, "Gloizer/Groizer X" had a considerable impact in Brazil, where it was aired under the name O Pirata do Espaço ("The Space Pirate") in 1984/1986 at the Manchete Network. Only two mecha anime were shown in the country, and "Groizer" was the only full-exhibited (the other one, Voltes V, had only five episodes aired there). In Latin America, the anime was aired under the name "El Justiciero".
