Blastoise is a Water-type Pokémon from the Pocket Monsters series, known for its large size, powerful water cannons on its back, and strong defensive capabilities. As the final evolution of Squirtle, Blastoise evolves from Wartortle starting at level 36. It serves as a reliable partner in battles, capable of withstanding attacks and launching powerful water-based moves like Hydro Pump. In the series, Blastoise is often depicted as a loyal companion to its trainer and is a popular choice among Pokémon trainers for its balance of offense and defense.
