General Dange is a Boazanian colleague and ally of Doctor Kentarō Gō. He was a member of Boazanian nobility, and military general until he deliberately broke his horns, because he "..believed in equality and decided to fight for it" and joined the rebellion against Emperor Zambajil. When Dr. Gō returned to Boazania, he broke him from capture and escaped with him to earth, along with a handful of rebels. He assisted Voltes V by piloting the "Mechanical Eagle" and installing new weapons upgrade components during Mid-battle.
