Nidoqueen is a large, powerful, bipedal Pokémon. They have thick yellow armor plates all over them. Its horn is smaller than Nidoking's, but it's still strong and produces large quantities of concentrated venom. Nidoqueen can use powerful moves such as Body Slam to paralyze its foes and then finish them off with Mega Punch or Iron Tail.
Nidoqueen can have either the ability Poison Point where a foe has 30% chance of being poisoned or Rivalry where if the foe is the same gender Nidoqueen's attack will be higher.
It is based on various mammals such as Hamsters, Rabbits, or Mice. As well as being based on some reptiles, mostly theropod dinosaurs. Its name is possibly a combination of a parody word of needle and queen.
Despite having genders, Nidoqueen, along with its pre-evolution Nidorina, are unable to breed, however their male counterparts Nidorino and Nidoking can breed.
No other Pokémon have the same type combination as Nidoking and Nidoqueen.
Despite being in the No Eggs group in the games, Nidoqueen was capable of breeding in the anime.
