Emboar @ Choice Scarf
EVs: 252 Atk / 4 SpD / 252 Spe

Checking Vikavolt offensively is probably one of the easier ways to deal with this behemoth of a pokemon. Looking for defensive answers almost led me to post something like Spdef Camerupt but it's probably better to post something viable and reliable in the current meta. Emboar can switch in on a Bug Buzz relatively safely and OHKO back with Flare Blitz. Pressuring Vikavolt with Stealth Rock while forcing it out with doubles to Emboar definitely works.
