Created by Go Nagai
On Fuji TV
A classic 1970s super-robot anime built on heroic action, alien invasion stakes, and the found-family bonds of young pilots defending Earth.
The story revolves around Duke Fleed who is a survivor of the Vega Star, raised by Dr. Umon as his adoptive son, and known as Daisuke Umon on Earth. Years after his arrival, he's faced with the threat of King Vega and his army, who want to conquer the Earth. With his friends Koji and Hikaru (and later his kid sister Maria Grace), Duke decides to fight back using his best weapon, the almighty Grendizer.
