Vigoroth is a white, sloth-like, bipedal Pokémon with a teardrop-shaped tuft of red fur on its forehead. It has stubby ears, two small, triangular teeth in each jaw, a brown lower jaw, and large eyes encircled by brown rings. There are two stripes on its back, which are also brown. Its arms are long, and its hands and feet have two sharp black claws. The undersides of its hands and feet have circular red pads, and its rear also has a baboon-like patch of red. The fur on its chest, tail, and sides of its maw are shaggy.
Vigoroth's heart beats at a tenfold tempo, and it cannot sit still for even a minute. Attempting to stand still or sleep raises its stress level and agitates its blood. It likes to go berserk by spinning its arms to destroy anything in its path. It runs wild through the jungle. Due to its rampages, it is always hungry.
