This action/adventure game adapted from the cult animated series will immerse you in the heart of the universe of its creator, Go Nagai, and will give you the chance to pilot the most powerful robot and fight the forces of evil. After Planet Fleed is destroyed by the Empire of Vega, Daisuke takes refuge on our planet. Taken in and adopted by Genzo Umon, he lives at the Shirakaba Farm. While Vega's invasion of Earth is imminent, Daisuke will defend planet Earth with the help of Grendizer, the titanic robot hidden deep inside Genzo Umon's observatory. With the help of Kôji Kabuto, the prince of Planet Fleed will constantly repel Vegas' attacks and fight his terrible robots, the Monstronefs, which were sent to destroy him.
