Ogerpon

Ogerpon is a strong offensive Pokemon that is unique in being able to check many top Pokemon such as Incineroar and Flutter Mane thanks to its ability Defiant and Speed-boosting Embody Aspect after Terastallization. Combined with access to Follow Me and natural immunity to Spore, Ogerpon is capable of being a constant threat while still providing good supportive value.

Ogerpon is almost exclusively used on teams built around Dondozo. With its ability Defiant, Ogerpon can be used to punish Incineroar and Gouging Fire, disincentivizing them from weakening both Dondozo and Chien-Pao and even picking up a clean OHKO on Incineroar with Superpower. Once Terastallized, It can outspeed and OHKO Flutter Mane and both Urshifu formes, which are difficult for Dondozo and Chien-pao or Dragonite to handle.

Ogerpon struggles against Pokemon that resist Grass STAB as Tornadus and Raging Bolt as well as foes that outspeed it, either forcing Ogerpon to Terastallize or be unable to attack before fainting, such as Chien-Pao, which outspeeds and can survive one hit thanks to it usually holding a Focus Sash. Ogerpon's Grass typing means it's weak to common threats such as Chien-Pao and Gouging Fire, and its middling bulk makes it unable to take more than two attacks most of the time.
