Blastoise

Blastoise (Japanese: カメックス Kamex) is a -type Pokémon. Blastoise was also the version mascot for Pokémon Blue.

Appearance
Blastoise are a large tortoise-like Pokémon with some similar features of its pre-evolved forms. Like its pre-evolved forms, Blastoise has a shell that covers its entire body, which can also be withdrawn into. Contrary to Squirtle and Wartortle, Blastoise's shell features large water cannons located on the top left and right sides. The water that comes out of the cannons can punch through thick steel.

Special abilities
Blastoise, like Wartortle and Squirtle, can shoot out water, though not from its mouth, but its large cannons. These cannons allow water to be shot at much greater force, which leaves them the backing force of all water attacks.

In the anime series
Gary Oak was revealed to have a Blastoise in the episode The Ties that Bind, which was originally a Squirtle that he received as his starter Pokémon from his grandfather, Professor Oak. Gary used his Blastoise during the Silver Conference as his trump card to battle Ash Ketchum's Heracross, which it defeated with ease using Hydro Pump. It then put up a strong fight against Muk by using Rapid Spin, which made Ash withdraw Muk. After Ash sent out Bayleef, Blastoise finished things off quickly by using Bite. It, however, was defeated by Charizard's overwhelming Seismic Toss resulting in a loss for Gary.

Cissy of the Orange League used a Blastoise against Ash in a race during the episode Fit to be Tide. This race was one of the challenges Ash needed to overcome in order to get the Coral-Eye Badge.

A Trainer named Neesha owned a Blastoise named "Shellshocker", seen in the movie Mewtwo Strikes Back. Mewtwo had a cloned Blastoise to fight Shellshocker. Before Gary Oak went to the Hoenn region he left all his pokemon at his Father's lab and not Blastoise.

Evolution
Blastoise is the evolved form of Wartortle, as of level 36. Blastoise is the final evolution of Squirtle.

Game info
Blastoise first appeared in the Generation I games as the final evolved form of Squirtle. Blastoise are not obtainable in the wild and thus can only be obtained by trading in games where they are not received through events. A Blastoise is owned by Red in Pokémon Gold and Silver, as well as in their remakes. In the remakes, it is level 84, making it the strongest Blastoise to be owned by a foe. Its moveset with Red is Blizzard, Focus Blast, Hydro Pump and Hydro Cannon.
