Nidorino is a Poison-type Poison Pin Pokémon.
Nidorino is a light purple, quadruped Pokémon. It has several darker purple spots across its body. It has large, spiny ears with teal insides, narrow black eyes, and a long snout with two pointed teeth protruding from the upper jaw. It has a ridge of toxic spines on its back, and a long, pointed horn on its forehead. The horn is harder than a diamond and capable of secreting poison on impact. Its short legs have three claws on each foot. This is a male only species; the female counterpart is Nidorina.
Nidorino is independent and fierce, often described as violent and easily angered. It uses its ears to check its surroundings. If it senses a hostile presence, all the barbs on its back bristle up at once, and it challenges the foe with all its might. Nidorino live in hot savannas and plains.
