Background Information - Nidoqueen, the Queen of Whoopass
Nidoqueen is a fan-favorite appearing throughout the Pokemon anime series, the anime featuring Nidoqueen with multiple trainers, most notably Gary Oak and Dani, one of the Orange Island Gym Leaders however arguably it's most hilariously best moment to me as a kid was the time when this couple appeared, having a double battle with Ash & May, and showed off Nidoking's and Nidoqueen's combined Submission attack. Nidoqueen has also appeared in Pokemon Adventures in the hands of Kanto fem protag, Green (Or Blue in Japan) who is one of her major team players during the FRLG and Emerald arcs, however the most famous user of Nidoqueen is undoubtedly Giovanni's Nidoqueen who was a a force to be reckon with that almost defeated Red's highly-trained Snorlax in one shot. In fact Giovanni's Nidoqueen also had the most memorable appearance out of any Nidoqueen in another medium in it's debut in Pokemon Origins where just like Snorlax, it absolutely annihilates Charizard.

The first time I came across Sheer Force Nidoqueen was actually during my time in Rating Battles when this caught me by complete surprise, having no idea that Sheer Force Nidoqueen was this strong from it's Special Attack, so I just to look it up of what was the deal with this Nidoqueen I saw and it turns out it's a Sheer Force set. You got the usual STAB, the ice-type moves for taking down annoying flying-types like Zapdos and Focus Blast against a variety of normal types that Earth Power just can't quite do the same, except for Porygon2, don't even try. Just switch out.

Standard Hazard User set. That's really all I have to say, neat though that Nidoqueen has access to both toxic spike and stealth rocks though.
Ah Nidoqueen. I still remember you from the very first time I played Pokemon Yellow. Young me was too impatient to raise a balanced 6-man team (Which was actually kinda logical given how annoying the grinding was back then) so raised soloed the entire game with just a Nidoqueen. The fact that Nidoran (F) learned Double Kick was a godsend against Brock's gym after my Pikachu ran into obvious issues, and I also remember debated whether or not to evolve my Nidorina into Nidoqueen before or after Misty's gym given the added Ground type. In subsequent replays of that game I always chose Nidoking though. Actually, what set the sovereign Nidos apart back in gen 1 was their incrediblely wide movepool giving them access to TM's like Bubblebeam, Thunderbolt, Ice Beam, Surf, and Fire Blast. Talk about wide coverage at a time where most Pokemon back then were lucky to get an attack outside of their STAB and a Normal attack!
Anyways, the game has changed a lot since gen 1, and Nidoqueen now faces still competition from a lot of Pokemon including it's male counterpart which has better speed and offenses. That's not to say less of Nidoqueen given it's bulkier than the king and still has pretty much all the moves that it does. So don't write Nidoqueen off just yet.
Hazard Play
Ability: Sheer Force
Item: Leftovers
Nature: Impish/Bold
EV's: HP: 252 Def: 156 Sp.Def: 100
Moves:
Poison Jab/Ice Beam
Earthquake/Earth Power
Toxic Spikes
Stealth Rock
Set Details:
Pretty self explanatory. Set up your entry hazards of choice where Tox. Spikes spreads disease and Stealth Rock does damage and hit Flying types that resist one of Nidoqueen's two STAB's. With Sheer Force Poison Jab becomes Nidoqueen's strongest move and Earthquake serves as a secondary STAB. THough you can opt for a special set replacing Poison Jab with Ice Beam and Earthquake with Earth Power since both moves get the ability boost and has better coverage against certain check. Change the nature accordingly to suit this.
Also cool Nidoqueen/Nidoking signature. They look like some kind of J-Pop couple or strangely reminds me of this card anime I once saw as a kid, girl protagonist and some tsundere boy? Ring any bells?
