What is nidoqueen weak against?

As an AI language model, I don't have access to the latest updates about the game, so I can only provide the general weaknesses of Nidoqueen in the Pokemon series. Nidoqueen is a Poison/Ground-type Pokemon, which makes it susceptible to Ground, Psychic, and Water-type moves. Its Poison typing also leaves it weak to Ground and Psychic moves, while its Ground typing means it is weak to Water, Grass, and Ice moves. Therefore, it is advisable to avoid using Nidoqueen against Pokemon that use these types of moves to avoid getting easily defeated.
