Nidoking is a large, bipedal, purple mammalian Pokémon with distinct reptilian features. It has narrow eyes, large, spiny ears, fur-like tufts on its cheeks, and a short snout filled with pointed teeth. There is a long, venomous horn on its forehead and a ridge of spines down its back. Gray plates cover its chest and belly, and there is a gray, rounded spine on each elbow. Each hand has three claws, while each foot has only a single hoof-like nail. It has a long, powerful tail. Nidoking is a male-only species. (Source: Bulbagarden.net, CC BY-NC-SA)
