Blastoise is a large, tailed bipedal, blue tortoise-like Pokémon with a tough brown shell and two powerful water cannons, which are steel-like in appearance, that jut out of the top sides of its shell. The cannons can be withdrawn inside the shell, or rotated to point backwards; this enables Blastoise to commence jet assisted rams. Blastoise’s head sports triangular ears and is strong and sturdy in shape, allowing it to ram into foes in battle. Blastoise’s arms are thick and patterned with striations, possessing three claws on the hands. The white rim of the shell also encircles the arm. Unlike Wartortle and Squirtle, Blastoise’s tail is blue and stubby.
Despite their size, Blastoise are very gentle and calm Pokémon. They may be wary at first but can be very good allies in battle. They mainly take the role of leaders in large groups of Squirtle or Wartortle. They firmly plant their feet on the ground before shooting water from the jets on their back, deliberately making themselves heavy to withstand the recoil of their water jets.
Blastoise can be found living on island beaches near the ocean, but their preferred habitat seems to be freshwater ponds and lakes. This Pokémon is most likely to be found in Kanto.
This Pokémon was unavailable prior to Generation I.
