Who is your best Super Smash Bros Brawl character?

My best one is Sonic. A good thing about Sonic is that he can adapt to all kinds of stages, for example a platform stage like Norfair, a plain stage like Final Destination etc. Also Sonic has good jumping abilities and his third jump goes quite high. He is also fast (the fastest character) and he causes good damage. The only thing Sonic lacks is a good finishing move to send the opponent flying, he may can cause damage but he doesn't have a good finishing move (i'm not talking about Final Smash) to knock the opponent off field. His final smash though is one of the best Final Smashes in the game, considering that one hit cause about 30 damage, and also he doesn't lose if he gets off the sidelines of the stage while he's super sonic. The only thing is that you have to learn to control the speed, but once that's done you can easily beat 2 opponents.
