Nidorino

, Known as the Poison Pin Pokémon, are a larger and stronger form that Nidoran ♂ take when they gain enough experience. Nidorino look somewhat like a rhinoceros and a rabbit with needles and horns covering its body. Nidorino is more aggressive than Nidoran ♂ and is quick to attack when it notices a threat; its large ears are always on the lookout. The diamond-hard horn on its head secretes a powerful venom and on impact with an enemy, poison leaks out. If it senses a hostile presence, all the barbs on its back bristle up. Nidorino is the male counterpart of Nidorina.
