007 Squirtle

Squirtle (Japanese: ゼニガメ Zenigame) is a Water-type Pokémon introduced in Generation I.
It evolves into Wartortle starting at level 16, who evolves into Blastoise starting at level 36.
Along with Bulbasaur and Charmander, Squirtle is one of three starter Pokémon available at the beginning of Pokémon Red, Green, Blue, FireRed, and LeafGreen.
Squirtle is a light blue bipedal turtle with its most notable feature being the hard shell on its back. This shell forms and hardens on its back after birth. It could perhaps be distantly related to some other turtle-like Pokémon, such as Torkoal and Turtwig, but Squirtle seems to only be closely related to its evolutions.
Squirtle's shell is an extremely helpful defensive tool. It can withdraw into the shell to block physical attacks. Its smooth, hard shell and head also aid it in other ways, such as minimizing its resistance in water to increase its swimming speed, and allowing it to launch attacks like Rapid Spin and Skull Bash.
Squirtle is a natural-born swimmer. However, due to its size, it's easier for it to transport something small (like a Pikachu) than to carry its Trainer.
Its jaws may not look like much, but they are strong enough that a Squirtle can learn to use a Bite attack.
Squirtle's tail seems to resemble that of a Squirrel's tail, which allows it to use moves such as Tail Whip and Aqua Tail.
