Dragonite

Thanks to the sheer power of Tera Normal Extreme Speed, Dragonite is one of DOU’s biggest threats, threatening to KO a large portion of the metagame. Dragonite also has excellent coverage, allowing it to hit any Pokémon that aren't afraid of Extreme Speed, such as Gholdengo and Iron Treads. Dragonite’s Dragon/Flying allows it to take attacks such as Chi-Yu's Heat Wave and Palafin's Jet Punch while also granting it immunity to Earthquakes from Garchomp and Great Tusk. Tera Normal also allows it to survive threatening Dragon- and Ice-type attacks. Inner Focus lets Dragonite avoid Attack drops from Intimidate and flinches from Fake Out. Dragonite is most commonly paired with Chien-Pao, as Sword of Ruin lowers the Defense of foes, allowing Extreme Speed to deal more damage. This pairing is preferred by offensive teams but can fit on other archetypes appreciate Dragonite's power and priority. Due to Dragonite's heavy dependence on Extreme Speed, Pokemon that can block priority moves such as Farigiraf, Tsareena, and Indeedee-F limit its effectiveness. Dragonite also struggles against Pokémon with high physical bulk that can take an Extreme Speed and threaten it in return such as Great Tusk, Iron Hands, Amoonguss, and Garganacl. Additionally, Dragonite is greatly hindered by Stealth Rock, which nullifies Multiscale and limits its longevity.
