Blastoise seems to be a giant, blue tortoise that stands on two feet. Its shell is a cross between a regular shell and a tank. It has chubby legs and arms, along with a chubby, short tail. He has a tan underbelly, and his arms and legs seem armored. It also has small ears.
Mega Blastoise now how only one tank on its shell, and is much longer, going over its head. Its ears are more detailed, and his lower jaw is bigger with its eyes turning red. It has grown brown shells on its hands, also with a silver tank sticking out. Its toes are bigger.
