Summary
As the crown prince and only survivor of the destroyed Planet Fleed, Duke Fleed sought refuge on Earth after its devastation by King Vega’s forces. He swore to defend his new home while seeking vengeance against Vega and his subordinates. Piloting the super robot Grendizer, Duke combats repeated invasions throughout the 74 episodes of the Ufo Robot Grendizer series, aided by former Mazinger Z pilot Kouji Kabuto, who acts as his sidekick. On Earth, Duke assumes the alias Daisuke Umon and is adopted by Professor Umon, the head of the Space Science Lab, allowing him to pass as an ordinary human. He is employed by farmer Danbei Makiba. His true identity and extraterrestrial origins remain secret, known only to Professor Umon, Kouji Kabuto, Danbei’s daughter Hikaru, and her younger brother Goro.
