Nidorina (Japanese: ニドリーナ Nidorina) is a Poison-type Pokémon. She evolves from Nidoran♀ starting at level 16, and evolves into Nidoqueen when exposed to a Moon Stone.
Nidorina is comparatively larger than her pre-evolution, though she loses the forehead horn, whiskers, and incisor teeth. She remains quadruped. Nidorina is also turquoise in coloration instead of bluish lavender, with a pale underside. Nidorina's poison spikes are larger and probably more potent; she has also gained the ability to stand on her hind legs.
