Nidoqueen (Japanese: ニドクイン Nidoqueen) is a dual-type Poison/Ground Pokémon.
It evolves from Nidorina when exposed to a Moon Stone. It is the final form of Nidoran♀.
It is related to the Nidoran♂ line, but unlike Nidoran♀, Nidoqueen cannot breed.
Nidoqueen is a large, bipedal blue Pokémon with distinct reptilian features. Its lower jaw, chest plates and lower torso are cream-colored. It has a horn on its forehead, narrow black eyes, and large, spiny ears. There are toxic spikes running down the length of its back, and its body in encased in extremely hard scales that serves as excellent protection from any attack and stand up when Nidoqueen is excited or provoked. It has a thick, powerful tail. This is a female only species; the male counterpart is Nidoking.
Nidoqueen can be quite fierce and is very protective over its young. This Pokémon is at its strongest when it is defending its young, and will try to seal the entrance to its burrow to protect them. When in contact with foes, it can poison them with the spikes from its back or cause small tremors by slamming the ground. It is also adept at sending foes flying with harsh tackles and it uses its hefty bulk to execute powerful moves. Nidoqueen lives in hot savannas and plains.
