Scrafty is a bipedal lizard-like Pokémon. It has oval, wide-set eyes with small pupils and gray eyelids, as well as small nostrils and a wide mouth with bared teeth. It sports a red crest on its head, similar in appearance to a mohawk. Baggy yellow skin hangs off its shoulders, falling halfway down its back. Scrafty's body is orange, with thin arms and a gray, scaled belly. Its lower body and tail are covered by loose yellow skin resembling baggy trousers. On its tail is a single red scale.
Scrafty is powerful enough to kick through concrete blocks, and can also spit acidic liquid from its mouth. It can protect itself while attacking by pulling up or folding the loose skin around its waist. Scrafty lives in groups with other members of its species. Groups determine hierarchy by crest size, with the Scrafty having the largest crest becoming the leader. A group will attack anything that comes within its territory.
