I had to pick Wilt for this one. Not only is he very kind, selfless and helpful most of the time, but he also has one REALLY nasty side that only comes out whenever he is offended (such as when Bloo made the joke about being tall) or angered in any way. He also doesn't seem to handle being put under any kind of pressure very well, either (example-when he had to cover for Mac and Bloo in "Bus the Two of Us"). It makes him feel more realistic and it's possible that he's the deepest character on the show (although I'm not totally sure if he is because there are other characters with a great amount of depth to them as well), so because of this I had to go with him.
