Heero appears to most of those around him as an antisocial, guiltless, emotionless, cold hearted killer; however, this facade. Numerous times Heero proves that he does have emotions, cares about other human beings, and does not really desire to kill. Heero was trained by Dr. J to be the “perfect soldier” and in that training all of Heero’s emotions were deliberately repressed. The theory, as it goes, is that if a soldier can kill with out any emotional reaction then he has obtained a state of perfection. Heero’s perfection continues to support him until he discovers a thing called girls. When Heero is around Relena he can’t seem to keep his facade in place and thus releases some of the repressed emotions.
Heero also has a problem with trusting others. It is evident through out the entire series that he is reluctant to have people watch his back. But with people like Duo around, who make it so hard to not like them, Heero begins to trust the pilots and almost gain more confidence with them there to support him.
Over all Heero is a psychological enigma. One that, I think, only the writers know the true reasons for his mannerisms and actions.
This mysterious youth was sent from the L1 space colony cluster to fight against Oz. He goes by the alias Heero Yuy, after the martyred leader of the space colonies; his real name, like almost everything else about him, is unknown.
Heero has been trained since childhood for his role as pilot of the Wing Gundam, an upbringing that has made him cold and ruthless. But thanks to his years of training, Heero has become a perfect soldier equally skilled in personal combat, explosives, and computer hacking.
