Granbull is a purple, bipedal, bulldog-like Pokémon. It has a prominent lower jaw with two long, fang-like growths. Its upper jaw has two small fangs. The jaws are so heavy that the Pokémon has trouble keeping its head up. On the sides of its head are flat, curved ears, and its small nose is black. There is a black collar around its neck with two small white markings on it. Around its wrists are two black band markings, and it has a short tail. Despite its fierce appearance, it is actually very timid. Unless Granbull is startled, it will not bite indiscriminately. If attacked, it will flail about to fend off its attacker. Granbull wanders around urban areas.
