The biggest difference between squirtle and their evolution, wartortle, is that wartortle is more battle-oriented, waiting for the next attacker to destroy. They are normally puppy-dog loyal to their trainers who, for the most part, had them their whole life and would do anything to defend them. Wartortle look more mature than their smaller counterparts, and they've dropped the "Tiny" in the classification name, becoming the "Turtle Pokémon". Evolves from Squirtle and into Blastoise .
