Created by Shotaro Ishinomori and produced by Toei Company, Akumaizer 3 ran from October 1975 until June 1976 (38 episodes).

The show follows the adventures of three demon refugees from the Akuma (Devil)  Clan, a vast empire that exists below the surface of the Earth. Having been cast out they now stop the Akuma Clan from attacking the surface world.

Akumaizer 3 are Xavitan, a half-demon swordsman, Evil, a somewhat vain and foppish sharpshooter, and Gabra, a slow- and dim-witted strongman. Together, they make up the superheroic team of the show’s title. At the end of the series, the heroes’ bodies are destroyed, but their souls survive to be reincarnated in the direct sequel to the show Choujin Bibyun.
