::The Perfect Soldier::

     At a young age, Heero is trained to feel no emotion and be an effective killing machine.  He was raised by an assassin, underwent much physical and mental training in space, and was prevented from having a normal social life.  This is not the recipe of a good, stable childhood. 
     His mission is his life, and he has an almost suicidal outlook.  Knowing nothing else but war, Heero believes he must fight, even if he dies trying.  He is calm and quiet most of the time, but becomes distracted by the emotions he was trained not to surrender to.  This boy appears to take pleasure in blowing stuff up - in one of the first episodes, he laughs like a maniac at the sight of the destruction he caused. 
     All in all, Heero is a mystery.  We don't know much about his past, he seems to have a few psychological problems, and he doesn't even use his own name.  We do know that he does have feelings, even if he appears inhuman at times.
