Weavile

Weavile is the textbook definition of a late-game Pokemon, as it is capable of sweeping large portions of the UU metagame, which is mostly due to its blistering 125 base Speed. This allows Weavile to outspeed the majority of the unboosted metagame—only Meloetta-P and Crobat are faster. Weavile's base 120 Attack lets it tear opposing teams in two thanks to its STAB moves, Ice Punch and Night Slash. However, its super-thin 70 / 65 / 85 Defenses still hold it back. Also, Weavile's typing leaves it with a crippling Stealth Rock weakness, which prevents it from switching in and out of a match effectively, and a weakness to the most common type in UU, Fighting-types.
