Probably the best special sweeper in the game, bar Ubers of course. This thing is an absolute beast, and it should be treated as such. Quiver Dance is even more broken than Dragon Dance, as it gives Volcarona some extra Special bulk while it gets a special version of Dragon Dance. The choice between Fiery Dance and Fire Blast comes down to a potential SpAtk boost vs. POWERRRR. Bug Buzz is a reliable, base 90 power STAB move. Hidden Power Rock hits Dragons and Heatran (to some extent), the two best candidates for walling this set. Volcarona [i]needs[/i] support in Rapid Spinning; it takes 50% health from Stealth Rock and it isn't even immune to Spikes. Starmie, Donphan, Foretress, Claydol, etc. They all work, just make sure Rocks aren't on the field when Volcarona comes in. Other than that, Volcarona is a tough Pokémon to beat, especially if you get some hax and Flame Body activates on a physical counter. The choice between Leftovers, Life Orb, or Lum Berry is longevity, power, or a better chance to set up. Take your pick.

You know what's funny? I didn't even realize "Behemoth" was a pun until [i]after[/i] I posted this. I'm so [s]not[/s] clever...
