The best character in Super Smash Bros. Brawl.

I will admit this up and down... All over the place. Pokemon Trainer is the BEST character on brawl.

Pros-
-Everything is here. Speed, Power, Balance. Squirtle is one of the faster attacking characters on the game. Ivysaur is a mix of strength and evasion. Charizard is a fucking brute. No way around it.
-Changing is quick. There's no string attached to swaping Pokemon.
-Not based on Stamina as originally planned. They share percentages, like everyone else.

Con-
-No Down B attack, or down special. This is instead to swap Pokemon. This isn't so much a con, as a learning curve.

Other than Pokemon Trainer... DEFINITELY check the following characters-
Sonic.
Pikachu.
Captain Falcon. [HUGE upgrade from Melee.]
Meta Knight.
Luigi.
Zelda.
Wario.

Those are MY favorites so far. I have not played with Snake very much, so I cannot give an exact opinion on him.

But seriously. Play with Pokemon Trainer. You will not be disappointed.
