Goth's gonna win this round but I'm going to also nominate Talonflame.
It's basically the face of an entire playstyle (birdspam) and invalidates so many Pokemon that would be good otherwise. It's a terror for offensive teams because priority Brave Bird just annihilates them if they don't have anything that resist it. Even then, resists without reliable recovery are prone to being worn down or even damaged hard by Flare Blitz because it's still fast af without Gale Wings.
Sure, 4x weak to SR, recoil moves, etc. But this thing is a failsafe to set-up sweepers and scarfers, can screw over its fat switch-ins with Will-o-wisp, or just U-turn into Duggy to trap Heatran which may be your only Talon counter. It's not as dominant now as it was when XY came out but guess why? Because the meta was forced to adapt to it and it's another one of the reasons why Landorus-T, Rotom-W, Tyranitar, and Heatran are so popular.
