Gundham Tanaka is a student of Hope's Peak Academy's Class 77-B, and a participant of the Killing School Trip featured in Danganronpa 2: Goodbye Despair. His title is the Ultimate Breeder. Gundham has an eccentric and somewhat dark personality, his delusions of self-grandeur likely stemming from an inferiority complex and chuunibyou syndrome. He claims that he was gifted with evil powers of the underworld, the result of "an angel and a devil" joining together. Gundham refers to other people as "pathetic human beings" and states that even the gods fear his abilities. He often rambles about his status as "The Supreme Overlord of Ice" and his interest in the dark arts, alchemy, and astral levels. Preferring to be alone, he prioritizes himself and taking care of the Devas over connecting with his classmates. For instance, in 1-2, he failed to help investigate the murder of his classmate after he lost the Hell Hound Earring and obsessed over recovering it. As a result, he initially comes off as self-centered and aloof. Despite making a poor first impression, Gundham offers comic relief in what he says to Danganronpa players and other characters. His outlandish responses and dramatic voice acting are reminiscent of a cartoon super villain. He sometimes goes as far as to compliment other characters if they say a "nice line," which teases at breaking the fourth wall. Gundham is notably contradictory—during his introduction, he tells Hajime Hinata to step forward and introduce himself, for Gundham will destroy Hajime once he does. It is heavily implied that though Gundham appears prideful and shuns spending time with mere mortals, he may actually feel lonely. He tends to cover up how he feels alienated from others; for instance, he claimed that he was "searching for solitude" before slowly wandering off.
