Dragapult

Sporting a near-unresisted STAB combination, highly customizable coverage moves to target its checks, and a Speed tier that outspeeds almost the entirety of the unboosted metagame, Dragapult strikes fear into entire teams as one of the best wallbreakers in the tier. Its Speed allows it to force out the majority of offensive threats, such as Urshifu-R, Garchomp, and unboosted Kartana, as well as cleave through weakened defensive cores, while its access to U-turn facilitates this by letting it pivot out against its checks switching in so they can be overwhelmed in the long run. Its coverage options ensure that it is not limited to using U-turn early-game either—Flamethrower, Thunderbolt, and Hydro Pump can nail common checks super effectively, such as Ferrothorn, Melmetal, Tapu Fini, Toxapex, Landorus-T, and Heatran. Moreover, teams that overprepare for its special sets can find themselves swept by the relatively uncommon but immensely dangerous Dragon Dance sets that greatly punish more passive checks, namely Blissey and Gastrodon. Its Ghost / Dragon typing also gives it numerous entry points in a game, as it can leverage its myriad of resistances to soak up otherwise dangerous attacks in a pinch, such as Surging Strikes from Urshifu-R and Steam Eruption and Flamethrower from Volcanion. So despite Dragapult's susceptibility to passive damage that can limit its longevity as an offensive pivot, make no mistake: the Galarian dragon will put teams to the sword like no other Pokemon in SS OU.
