Sixteen years after Ryouma Nagare, Hayato Jin and Benkei Kuruma defeated Emperor Hyakki, research has begun to develop a new set of Getter Machines in order to fight the threat of a new, cyborg-like species known as Metal Beasts, led by the evil Professor Rando of the "Vega Zone". Leading this project is Hayato himself, who soon scouts and enlists three young pilots : Go Ichimonji, a young professional athlete, Sho Tachibana, the daughter of Prof. Tachibana (leader of the Getter-Go project) and a skilled sword-fighter, and Gai Daidou, a former Getter mechanic. Together, these three pilots use a new set of Getter Machines to form the super robot known as "Getter Robo Go", and begin a battle to stop Rando once and for all.
