Squirtle

Squirtle is a Water-type Pokémon and one of the three starting Pokémon in Pokémon Red Version and Pokémon Green Version, later localized as Pokémon Red Version and Pokémon Blue Version. Its name is a portmanteau of squirt and turtle. In the Pokémon series, it evolves into Wartortle and later into Blastoise.

Super Smash Bros. Melee
In Super Smash Bros. Melee, Squirtle is the first Pokémon to appear on the Poké Floats stage, and it has a trophy.

Super Smash Bros. Brawl
Squirtle is a playable character in Super Smash Bros. Brawl. However, it takes commands from the Pokémon Trainer, who is the real mastermind behind Squirtle's actions. The other two Pokémon used by Pokémon Trainer are Ivysaur and Charizard. When the Pokémon Trainer uses Pokémon Change, his down special move, he returns Squirtle and sends out Ivysaur next, but when used with Charizard, Squirtle is sent out. Squirtle is the lightest of the group, but also attacks the quickest.

Squirtle's neutral special move is Water Gun, in which it charges an attack to spit water at opponents. Its side special is Withdraw, which causes it to charge directly ahead in its shell. Its up special is Waterfall, which causes Squirtle to leap into the air on a stream of water.

Like all Pokémon of the Pokémon Trainer, Squirtle shares the damage meter with the other Pokémon and has a special stamina stat. It is there to regulate the Pokémon changes. When the player changes Pokémon rarely or too often, the stamina of the Pokémon runs low. Squirtle can also wall jump, and has the ability to stick to walls. Finally, Squirtle has a similar type effectiveness to its games of origin, making it take more damage from grass attacks but less from fire attacks.

The Subspace Emissary
In the Subspace Emissary, the Pokémon Trainer starts out with only Squirtle. Eventually, he earns Ivysaur and Charizard.

Super Smash Bros. for Nintendo 3DS / Wii U
Although Squirtle does not return in Super Smash Bros. for Nintendo 3DS / Wii U, he appears as a trophy in both versions of the game.

Super Mario Maker
Squirtle appears as an Event Course costume in Super Mario Maker. It can be unlocked by completing the "I Choose You!" Event Course along with Bulbasaur and Charmander, released on February 11, 2016. Unlike the Pokémon costumes already available in the game, Squirtle, Bulbasaur and Charmander uses sound effects from the original Pokémon games.
