While Nidoqueen may seem like an unconventional choice for the OU tier, she is one of the few viable users of Toxic Spikes, which catapults her popularity. Nidoqueen's good typing and decent defensive stats allow her to stop many powerful physical attackers, such as Lucario and Tyranitar. While Nidoqueen is a solid Toxic Spikes user, her defenses are merely average by OU standards, meaning that powerful neutral attacks will heavily damage her and super effective hits will usually KO her. The fact that she lacks a reliable recovery move doesn't help her defensively, as she will often find herself low on health and unable to set up as easily. When using Nidoqueen, make sure that you use her as a go-to Pokemon against physical attackers whose STAB she resists (specifically, physical Fighting-types), as this is when she will find opportunities to set up Toxic Spikes. Overall, Nidoqueen is a good choice in OU if you want a Pokemon who can take a hit and support the team.
Nidoqueen's niche in OU is the ability to consistently set up Toxic Spikes, an ability that few other OU Pokemon share. The main reason to use Nidoqueen over more popular Toxic Spikes users is her ability to switch in on threats other users cannot, such as Lucario, Jolteon, and Tyranitar. She is also able to absorb an opposing team's Toxic Spikes on the switch-in, something that only two other Pokemon who are commonly seen in OU, Roserade and Tentacruel, are capable of.
Nidoqueen will find the most opportunities to set up Toxic Spikes when she switches in on a physical threat whom she can wall, such as Tyranitar, or a slower defensive Pokemon, such as Blissey. Earthquake is used in the second moveslot as a form of STAB, hitting Pokemon such as Heatran for huge damage and dealing a decent chunk to anyone who isn't resistant or immune to it. Fire Blast is the main choice in the second moveslot as it allows Nidoqueen to hit Steel-types who don't care about Earthquake, such as Skarmory and Forretress, for solid damage. However, Super Fang is a viable alternative, allowing Nidoqueen to immediately strip any switch-ins of half their health, bar Ghost-types. Stealth Rock is the main option in the fourth moveslot, as it allows Nidoqueen to further support her team; she can set it up in the same situations where she sets up Toxic Spikes. However, Taunt can be used instead to shut down the likes of Blissey and Skarmory. She can then set up Toxic Spikes on the aforementioned Pokemon. If neither of these moves tickle your fancy, then Roar can be a good choice, allowing Nidoqueen to phaze out threats, rack up residual damage from entry hazards, and spread poison around the opponent's team with Toxic Spikes.
Team Options & Additional Comments >>>
Nidoqueen could potentially use a Rest + Sleep Talk set, but this makes her easily walled, and turns her into setup fodder for many dangerous Pokemon, namely Dragon Dance Gyarados. If you're interested in providing Nidoqueen with recovery, it's probably a good idea to stick with Wish support. Thunderbolt could be used over Fire Blast / Super Fang to allow Nidoqueen to hit bulky Water-types, especially Gyarados, but its usage is extremely minimal outside of that. Ice Beam is an alternate option to allow Nidoqueen to OHKO Flygon and Gliscor switch-ins, but Fire Blast is usually the better choice as far as a special attack is concerned. When choosing Nidoqueen's ability, it's generally best to stick with Poison Point. While the power increase that Rivalry potentially grants may seem appealing, the fact of the matter is that it will often leave Nidoqueen's attacks underpowered, as the majority of Pokemon are male. Poison Point can at least occasionally poison physical attackers, and while it isn't a great ability, it's better than Rivalry.
Checks and Counters
Depending on what special move Nidoqueen carries, certain Pokemon can cause her problems. If Nidoqueen lacks Ice Beam, then Flygon will easily switch in on her. If she lacks Fire Blast, then Skarmory and Forretress will waltz in and set up Spikes. Gyarados can freely switch in on Nidoqueen, set up Dragon Dance, and proceed to sweep her team; however, Gyarados must watch out for rare Thunderbolt variants. Opposing Rotom-A can easily switch in on Nidoqueen thanks to their immunity to Earthquake. They can then proceed to burn her with Will-O-Wisp or simply attack with Shadow Ball. Bulky Water-type Pokemon can switch in and threaten Nidoqueen with their STAB moves, but won't enjoy being poisoned by the Toxic Spikes that Nidoqueen sets up. At the end of the day, practically any Pokemon with decent defensive stats and a resistance to Ground-type moves will be able to take Nidoqueen on and come out on top. However, be wary of the special moves, namely Fire Blast and Ice Beam, that Nidoqueen may carry, as you could otherwise find yourself in a bad situation with the wrong switch-in.
