Volcanion

Volcanion makes for an interesting pick in the UU metagame with its unique typing, movepool, and stat distribution enabling a variety of viable sets and approaches. Given its high Special Attack, plethora of coverage options, and signature move Steam Eruption, Volcanion is most commonly used as a Defogger that can punish common entry hazard setters such as Mega Aggron and Hippowdon, and it can also be a strong wallbreaker with Choice Specs. Additionally, its solid defensive typing, overall bulk, and useful ability in Water Absorb allow it to serve as a respectable offensive check to Pokemon like Scizor, Mega Altaria, and Primarina and even let it run bulkier sets featuring Toxic. However, Volcanion has difficulty in dealing with the tier's omnipresent Dragon-types in Latias and Hydreigon. Its middling Speed tier and weaknesses to common attacking types in Rock, Ground, and Electric also open up opportunities for some of the tier's most potent wallbreakers in Terrakion and Nidoking to do big damage and for Pokemon like Mega Manectric and Rotom-C to gain momentum with Volt Switch. Lastly, Volcanion is vulnerable to all entry hazards, most importantly Stealth Rock, hurting its overall longevity and defensive utility if they are not cleared accordingly.
