Resume : The three "Spheres of Anderes" were artifacts created by the people of the alien empire of Sazoriani. These spheres were created 20,000 years ago to concentrate the energy of the constellation Scorpius and defeat Plasmani, another alien race, whom they held a long space war that was ended right on Earth. However, in order to retrieve the missing spheres, the Sazoriani led an invasion force of huge mechanical monsters to Earth. To combat the invaders, Dr. Godo, the last descendant of the alien race Plasman, built the mecha Ginguiser and entrusted the four robot that combined into it (Spin Lancer, Grand Fighter, Bull Gator and the aircraft Air Roin) to four children respectively: Goro Shigoron, Miki Akitsu, Torajiro Haranami and Zanta. The four, who toured around the world with their traveling magic show, also had real magical powers (the "point barrier") and therefore capable of controlling Ginguiser to stop the alien threat.
