Heero Yuy Organization Gundam Pilot Age 15 Ethnic Origin Japanese Place of Origin L1 Colony Cluster Height 156 cm Weight 45 kg Eye Color Prussian Blue Hair Color Dark Brown Real Name Unknown Alias Heero Yuy Gundams Piloted Wing, Wing Zero, Mercurius, Heavyarms and Epyon This talented pilot of the Wing Zero is the most grim of the pilots. Although his real name is unknown, he goes by the alias Heero Yuy, the assassinated pacifist leader of the colonies. Raised and trained to be a killing machine by the scientist Doctor J, equally proficient in mobile suit piloting, personal combat, damolitions and computer hacking. Though Heero's upbringing hasn't quite managed to squeeze all the compassion out of him, he is nonetheless callous towards his allies, and cold-blooded towards his enemies, and almost suicidally careless of his own life. His unexpected reluctance to kill Relena Peacecraft, after she discovers his identity, is the first step in Heero's gradual reclamation of his own humanity.
