Squirtle (ゼニガメ Zenigame?) is a playable fighter in Super Smash Bros. Brawl; it is one of three Pokémon that can be played through Pokémon Trainer, the other two being Ivysaur and Charizard. Squirtle is the only Pokémon used by Pokémon Trainer who is not an evolved form (Charizard and Ivysaur are evolved forms of Charmeleon and Bulbasaur, respectively). Squirtle is also the only playable Pokémon character in Brawl that doesn't have a pre-evolved form at all (Jigglypuff evolves from Igglybuff, Lucario evolves from Riolu, and Pikachu evolves from Pichu). Squirtle originated from Pokémon Red and Blue for the Game Boy, as one of the initial Pokémon the player can choose to start out with at the beginning of the adventure.
