Nidoran♂ is a Poison-type Poison Pin Pokémon.

It evolves into Nidorino starting at level 16, which evolves into Nidoking when use the Moon Stone.


Nidoran♂ is a small, quadruped rodent-like Pokémon. It is pinkish purple with darker spots, and has large, spiny ears, oversized front teeth, and red eyes. Its back is covered with many large spines that can release potent poisons if threatened. There is a long, pointed horn on its forehead. The size of this horn is indicative of the strength of its venom. Nidoran♂ is an exclusively male Pokémon, Nidoran♀ being its female counterpart. Nidoran♂ constantly listens for the sounds of approaching enemies with its large ears. Said ears have unique muscles that allow them to be moved in any direction, and even the slightest sound does not escape Nidoran♂'s notice. In order to listen to distant locations, it flaps its ears like wings. When angry, it extends its toxic spikes and charges, stabbing with its horn to inject poison. Nidoran♂ lives in open spaces, such as savannas and plains.
