Banjou escapes from Mars on a rocket with a solar-powered super robot called Daitarn 3, which was built with the special metals of Mars. Now eighteen years old and living on Earth in a luxurious mansion, Banjou fights against the Meganoids with the aid of his faithful butler Garrison and his two gorgeous companions Reika and Beauty.
