Ginguiser (超合体魔術ロボギンガイザー) is a Japanese mecha anime television series produced by Nippon Animation and co-produced by Ashi Productions. It ran from April 9 to October 22, 1977.[1]
Plot
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, with whom they fought a long space war that was ended right on Earth.
In order to retrieve the missing spheres, the Sazoriani led an alien 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 robots 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 are capable of controlling Ginguiser to stop the alien threat.
