Volcarona

Volcarona's access to Quiver Dance, coupled with a decent Special Attack and Speed, allows it to function as a setup sweeper that can snowball out of control if not stopped. Its diverse coverage options allow it to choose its checks to a certain degree. However, no matter the coverage option it chooses, Volcarona is bound to be walled by a significant number of relevant threats in the Doubles metagame. Volcarona also has a variety of utility moves in its movepool, enabling it to take up a more supportive role with Rage Powder. This allows Volcarona to redirect most attacks away from teammates and makes a great combo with its Fire STAB moves, which let Volcarona remove problematic Grass-types, which cannot have their attacks redirected by Rage Powder. That being said, it is not easy to fit Volcarona onto teams due to the amount of support it requires to function to its fullest potential. Volcarona also faces stiff competition from other, more popular Fire-types, such as Incineroar, Victini, and Volcanion, which can fulfill more useful niches in teams. As a bulky supporter, it has a niche over other popular support options, thanks to its unique combo of utility moves, allowing it to act as a redirection user, provide speed control, and even act as a phazer all in one slot. However, its mediocre physical bulk and poor defensive typing mean that Volcarona can be forced out easily by common physical attackers or bulkier Pokemon that can wall it reliably. The fairly common use of Stealth Rock in the Doubles metagame also makes it hard for Volcarona to function to its fullest potential.
