Nidoqueen

Nidoqueen is generally regarded as a more defensively oriented Pokemon, and with the many new toys that it received this generation, it can perform that job better than ever. While overlooked during the times on DPP, Nidoqueen was blessed with the ability Sheer Force from the Dream World to power up many of its attacks to sky high levels, even without investment. The Queen also boasts a decent defensive typing with key resistances to Fighting-, Bug-, and Rock-type moves; furthermore, it has immunity to Electric-type attacks. In addition, Nidoqueen is not affected by Thunder Wave or Toxic, and it can absorb Toxic Spikes on its own. With a good movepool containing support, phazing, and offensive moves, Nidoqueen has quite a few options to choose from that can support your team's needs. Nidoqueen, through the transition to BW2, became one of the most reliable Stealth Rock setters in UU because few Pokemon can use Rapid Spin against it safely. Blastoise is 2HKOed by Earth Power or Sludge Wave and fails to OHKO with Scald. Hitmontop is 2HKOed by both attacks as well. Xatu does not ever want to switch in because even defensive variants will not enjoy taking Ice Beam. Even Cryogonal is OHKOed by Fire Blast or Focus Blast and it cannot OHKO with Ice Beam, unless it's using an offensive EV spread.

Sadly, Nidoqueen is not without its flaws. A Base 76 Speed is average at best and a weakness to Ground-types often can hold Nidoqueen back against faster threats. Not to mention, in the fully offensive role, Nidoqueen is always outclassed by its older brother, Nidoking, which also boasts Sheer Force but has higher offensive stats. To boot, Nidoqueen has no recovery outside of Rest, Black Sludge, or Leftovers. Despite these drawbacks, Nidoqueen is a threat that should not be overlooked, and if you are looking for a solid defensive Poison-type to set up Stealth Rock or wreak some havoc as a bulky attacker, why not give Nidoqueen a chance?
