Crobat

Crobat acts as a fast offensive pivot thanks to its incredible natural Speed, allowing it to outspeed fast offensive Pokemon like Azelf, Zygarde-10%, Keldeo, and Noivern. Crobat can make use of its high Speed and offensive pivoting with STAB Brave Bird and U-turn to outlast checks such as Nihilego and Rotom-W, making it threatening to many common team styles. Taunt prevents would-be checks like Salamence, Skarmory, Hippowdon, and Chansey from recovering while also preventing the latter two and Amoonguss from using status moves. While Crobat's Poison / Flying typing allows it to switch in on Grass- and Fighting-type attacks from Pokemon like Zarude, Amoonguss, and Conkeldurr, it must beware switching directly into a status move like Stun Spore or Spore from Amoonguss, or strong attacks like Darkest Lariat from Zarude and Knock Off and Facade from Conkeldurr. Furthermore, Crobat's average bulk makes it struggle to switch in on strong attacks from offensive Pokemon like Hydreigon, Azelf, and Zygarde-10%. Crobat's lack of relevant resistances also makes it fear moves from Pokemon it would otherwise check, such as Facade from Conkeldurr and Hydro Pump from Keldeo. Lastly, Crobat is dependent on Heavy-Duty Boots to be effective, forcing it to play carefully against Knock Off users like Diggersby and Scizor. This flaw also forces Crobat to think twice about switching into Knock Off users it would otherwise counter like Tangrowth.
