How Do tu Describe Sonic The Hedgehog?

Thats hard... I will say, he is half human half animal so tu can not exclude human qualaties! *growl* If i had to discribe sonic, as sonic, I would say, he would have a knoch cut out of his ear because he has been in many fights... tu can just look at this picture.

he is charming, trustworthy, sweet, caring, loving, helpful, friendly, everything is perfect about him.
