Crobat

Crobat is among RU's elite Pokemon, with the defensive utility to check common Pokemon like Golisopod, Pangoro, Heracross, and Roserade and the Speed to revenge kill weakened setup sweepers like Mimikyu and Lucario. Crobat is the tier's premier entry hazard removal option, as it checks the Spikes users Roserade, Heracross, and Golisopod, and it's highly practical to fit Defog on a Pokemon with already-good role compression. Crobat possesses many other great support moves like U-turn to support wallbreakers, Super Fang to weaken the likes of Registeel and Rhyperior, Toxic for crippling bulky switch-ins, and Taunt to prevent setup and recovery attempts. Crobat also has an excellent Nasty Plot set that threatens to sweep, and it can turn the tables on typical Steel- and Rock-type counters like Steelix, Registeel, and Rhyperior with boosted Heat Wave and Giga Drain. However, as a Defogger, Crobat has poor matchups against most Stealth Rock setters like Registeel, Steelix, and Metagross. Spikes Klefki is also generally good at taking advantage of teams relying on it. Moreover, Crobat's reliance on Heavy-Duty Boots leaves it vulnerable to Knock Off from Pokemon it checks like Heracross and Golisopod. Nasty Plot Crobat's sweeps can often fall short due to its lack of power. The likes of Metagross, Incineroar, and Registeel can take even boosted attacks and leave it damaged enough for revenge killers like opposing Crobat and Choice Scarf Flygon. Furthermore, Raikou, Xurkitree, and Nidoqueen are common offensive checks that can take a boosted attack and OHKO it.
