Gamma 1 resembles his fellow Android Gamma 2 and wears a similar costume, though befitting his number designation Gamma 1 has a single fin upon his head. Hedo's design for Gamma 1 was inspired by one of the many superheroes he idolized in his childhood. He also wears a red cape, carries a red Ray Gun, and the number one on his chest is colored red as well. Like Gamma 2, his belt buckle features Greek letter Gamma (Γ) (ガンマ, ganma). He has a Red Ribbon Army logo on the left sleeve of his uniform.
