Dragonite

Dragonite fills a niche in OU as a dangerous sweeper thanks to its Multiscale ability allowing for easy opportunities to set up with Dragon Dance and sweep through opposing teams. Its typing and good bulk allow it to find setup opportunities against common threats for offense such as Mega Charizard Y, Volcarona, and Ash-Greninja, as well as balance staples like Gliscor and Heatran. Extreme Speed provides it with a solid priority move and revenge killing tool, letting it stand out compared to other Dragon Dance users such as Gyarados, Mega Charizard X, and Kommo-o. It can also select between Flyinium Z and Dragonium Z, providing it with strong Z-Moves to blow past targets such as Clefable and Rotom-W, respectively. Unfortunately, Dragonite is held back by its subpar Speed tier, with Pokemon like Kyurem-B outspeeding it before a boost and Pokemon like Mega Alakazam and most Choice Scarf users outspeeding it after a boost. Its typing also leaves it vulnerable to Stealth Rock, which both removes Multiscale's effect and takes away a chunk of Dragonite's HP. As a result, Dragonite needs a lot of support, especially entry hazard removal, to utilize its full potential, and it faces competition from other Dragon Dance users such as Mega Charizard X and Gyarados.
