Grendizer U - S01

Duke Fleed, the lone survivor of his destroyed home planet, flees to Earth inside a strange spaceship. Taken in by Dr. Umon, he grows up as the man’s adopted son under the name Daisuke Umon. Years later, King Vega and his forces set their sights on conquering Earth. With the help of his friends Koji and Hikaru-and eventually his long-lost younger sister, Maria Grace-Duke resolves to stand against them. His greatest weapon in this fight is the powerful mecha known as Grendizer.
