Wartortle are tailed, bipedal, indigo-blue turtle-like Pokémon with brown shells and long, furry tails and ears. Wartortle has small fangs protruding out of its mouth, brown irises, and three sharp claws on its arms. Small, oval shaped spots are located under their eyes. To maintain balance while swimming at high speeds, Wartortle move their unusual furry ears and tails. This tail, covered in rich, angelic thick fur, is so long that it sticks out a bit even when Wartortle withdraw into their shell. They use the fur to store air for extended underwater diving. As a Wartortle ages, algae may grow on its shell.
Wartortle is the evolved form of Squirtle and will evolve into Blastoise at level 36. It is more likely to run away from a trainer than to engage them in battle.
