Synopsis

Duke Fleed is the last survivor of the Fleed Planet. He escaped to Earth aboard a mysterious spaceship and was taken in by Dr. Umon, who raised him as his adoptive son under the name Daisuke Umon. Years later, King Vega and his alien army show up with plans to conquer Earth. Duke teams up with his friends Koji and Hikaru—and eventually his younger sister Maria Grace—to fight back. Their secret weapon is Grendizer, a powerful robot that becomes Duke's best chance at stopping the invasion.
