Dr. Hedo is the genius grandson of Dr. Gero, the scientist who created the Androids. An eccentric inventor with a passion for superhero culture, he creates the Gamma androids and Cell Max for the revived Red Ribbon Army before switching sides and joining Capsule Corporation. He is a central figure in Dragon Ball Super: Super Hero.
Dr. Hedo inherits his grandfather's extraordinary intellect but channels it in a very different direction. Where Dr. Gero was driven by vengeance against Goku, Hedo is motivated by his love of superheroes and tokusatsu media. He creates Gamma 1 and Gamma 2, a pair of androids designed to look and act like comic book heroes, complete with capes, poses, and a sense of justice. The Gammas are so well-made that they genuinely believe they are protecting the world, even when manipulated by the Red Ribbon Army into attacking the wrong targets.
Hedo's involvement with the Red Ribbon Army comes through Magenta, the son of Commander Red, who runs the organization's front company Red Pharmaceuticals. Magenta deceives Hedo by framing Capsule Corporation and the Z Fighters as villains, convincing him that his superhero androids are needed to protect the world from them. Hedo also reluctantly works on Cell Max, a massive bio-android based on his grandfather's Cell project, though he protests that the creature is unfinished and should not be activated.
After the truth comes out and Cell Max is defeated, Hedo recognizes that he was manipulated and accepts Bulma's offer to join Capsule Corporation. His transition from unwitting villain to legitimate scientist mirrors the franchise's broader theme of redemption. Hedo is a modern take on the Dragon Ball inventor archetype: brilliant, socially awkward, and ultimately good-hearted once he has the right information and the right team behind him.
