Hyuza is the chancellor of the Deathcula, and is a tall, frightening cyborg with a demonic death mask for a face. Hyuza lost his body in the battle of Saturn 15 years ago, when Shinji's father destroyed his spacecraft. He transferred his brain in the main computer of Hell’s Paradise, and then connected it to a mechanical body, becoming a cyborg. Cold and cunning, Hyuza wishes revenge toward humans so badly that he chooses as one of his plans the idea to smash Hell’s Paradise into Earth, even if this means killing himself and his people as well. His most trusted commanders are Perios and Gustav, but nevertheless Hyuza keeps them under tight control.
