Blastoise

Description
Blastois is a large, watertype, blue tortoise-like Pokémon with a tough brown shell and two powerful water cannons, which are like steel in appearance, that jut out of the top sides of its shell. The white rim of the shell also encircles the arm. Unlike Wartortle and Squirtle, Blastoise’s tail is blue and stubby. Blastoise also makes an appearance in Oak's Lab to defend the lab from the Rattata swarm. The rocket cannons on it's shell fire jets of water capable of punching holes through thick steel. It deliberately makes itself heavy so it can withstand the recoil of the water blasts it fires. Its ability, Torrent, makes it's water type moves more powerful when low on HP. You will see this because it will glow blue.

Blastoise also makes an appearance in a cutscene at the end of Oak's Lab.
