Charizard
From Mariopedia, a wiki on Mario, Yoshi, Wario, Donkey Kong, Super Smash Bros., and more!
Charizard is a fire-type Pokémon, and the full evolved form of Charmander. It will also be a playable character in Super Smash Bros. Brawl. However, it is not an actual new character, per se, but rather one of the Pokémon used by Pokémon Trainer, the real character. However, Charizard, as well as Squirtle and Ivysaur, does all the fighting for Pokémon Trainer. It is unknown what moves Charizard can use, however. Charizard is the last Pokémon to be used by Pokémon Trainer, coming after Squirtle and Ivysaur. When Pokémon Change is used while Ivysaur is in use, Ivysaur will be returned, and Charizard will be sent out. It is presumed that Charizard is the heaviest of the group. Not much is known, however.
