The program follows the adventures of three mutant superhero-refugees from the Akuma Clan, a vast empire that exists below the surface of the Earth, and their efforts to stop the Akumas from attacking the surface world. The three warriors 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.
