Dragonite

Dragonite, thanks to its high Attack, good typing, Multiscale, and large movepool, is a powerful wallbreaker and sweeper. Its typing provides it with excellent defensive utility, lending it resistances to common attacking types like Fire, Fighting, and Grass, making it a solid answer to threats like Breloom and Infernape. Furthermore, Extreme Speed and Dragon Dance make Dragonite a powerful late-game cleaner. Though Dragonite is able to beat most of its checks thanks to Earthquake and Fire Punch, its weaknesses to Stealth Rock and status as well as reliance on prediction hampers its longevity and effectiveness throughout the game. Furthermore, Dragonite is susceptible to being revenge killed by faster threats like Latias or Weavile and is walled by Clefable. Lastly, it suffers from the ubiquity of other, faster Dragon-type Pokemon like Garchomp and Latias.
