The designated pilot of the Forbidden Gundam, a model from the Earth Alliance's newly developed GAT-X series. He is a Boosted Man, a Natural enhanced via drug therapy and body modifications to outperform a Coordinator. As a Biological CPU, he is treated as just another component of his Mobile Suit, and his past has been completely erased. During the Alliance's Orb liberation operation, he and compatriots Orga Sabnack and Clotho Buer were fielded as gamepieces for Muruta Azrael. Ordinarily unsociable and deadpan, his personality shifts to take on a much more bare-knuckled combat style in battle that has given Kira Yamato and the rest of the Archangel crew a serious run for their money. His main hobby is listening to music, and his favorite genres are death metal and industrial music.
