Tyranitar

Tyranitar is among the metagame's most versatile Pokemon, as it can fulfill a plethora of roles with its bulk, power, versatile movepool, and unique ability to set permanent weather. Sand Stream is the only viable permanent weather setting ability in the metagame, effectively granting Tyranitar an oft uncontested and significant Special Defense boost that allows it to switch into common special attackers such as Latias and Raikou even without investment while also dealing consistent sand damage and disrupting rain teams. Tyranitar matches up well against the common lead metagame, as bulky Tyranitar can easily set up Stealth Rock against the likes of Mew and Rotom-H, while a Choice Scarf set Pursuit traps them, but its offensive capabilites and typing also make it a great wallbreaker, setup sweeper, and late-game cleaner. While Tyranitar boasts many favorable matchups, it must remain wary of its common weaknesses against Steel-types and Fighting-types, as the likes of Metagross and Hitmontop resist Tyranitar's STAB attacks and OHKO it back. Tyranitar is also prone to Intimidate, which significantly hampers its ability to trade favorably or become a fearsome Dragon Dance sweeper.
