Beast Boy is the changeling of the group, able to assume the shape of any animal – from a wolf to a pterodactyl. The green-skinned dynamo also has the corniest sense of humor and is the most eager to please and entertain the group. He's never in a bad mood and is enthusiastic about every new adventure. He'll try anything new and is not afraid to fail. In short, he's like the ultimate little brother – except that he can change into an alligator.
