Adrian Monk
He is shy, gentle, and driven by need of justice. And even if criminals hold him in little regard, he proves them that he is above his mental problems and eventually - resolves all cases, all problems, find all culprist, avenge all victims.
He is the kind of character that steals heart with his vulnerability and makes people admire him - even if he never asks for admiration and prices. He is himself. He is just... Monk.
