The Gutsy Galaxy Guard had emerged victorious in their battles against the Zonder Empire and the 31 Primevals, but a new threat had surfaced on Earth. In their quest to take down BioNet, the evil organization, GGG and Guy Shishio teamed up with their French comrades, Chasseur, and their latest creation, GaoFighGar. Renais Cardiff Shishioh, a former BioNet cyborg, joined Chasseur in their mission to avenge themselves against BioNet. Despite the ongoing battle, GGG and Chasseur were taken unawares as their bases worldwide were seized and their newly discovered "Q-Parts" and authentic Gao Machines were stolen by Mamoru Amami, who had been abducted and cloned by an even greater threat, the "Eleven Kings of Sol." With their backs against the wall, GGG ventured beyond the galaxy to save Mamoru and defeat the Eleven Kings of Sol before they caused more harm.
