Now that the Pokemon CoroCoro leaks revealed another of the three mysterious Pokemon found in X and Y, fans are hoping Diancie, Hoopa and Volcanion will be further utilized in future Pokemon games.

It's been confirmed that the upcoming Pokemon movie will feature Hoopa in its storyline. Although Volcanion has not been revealed yet, fans believe more will be revealed in the sequel to Pokemon X and Y or Pokemon Omega Ruby and Alpha Sapphire (tentatively titled Pokemon Z and Pokemon Delta Emerald).

"I seriously hope the next Pokemon game uses Diancie, hoopa and Volcanion in the plot," commented Afarr on PokeJungle.

"Team Flare will use Diancie to make Diamonds for money, Hoopa to steal and Volcanion to alter environmental conditions. This will call Zygarde to reset environmental damages, which Team Flare wants to happen to use Zygarde's power."

Others, however, believe Hoopa and Volcanion will be part of the post-game in Pokemon Z or Delta Emerald, or perhaps a DLC.

"I see Hoopa and Volcanion being part of the poast-game content much like the Delta Episode," wrote CoolGlaceon. "Hoopa because of its rings, [so] they could do a lot with that mechanic and VOlcanion because...Brandon?"

If you're a fan of hackers in Pokemon Omega Ruby and Alpha Sapphire, you might be familiar with the work of "Project Pokemon," a hacking team which has uncovered many hidden secrets in the franchise before. Recently, they uncovered an event which discussed aired television specials regarding Volcanion.

"This is a special edition of MVTV: Explorations of the Ancient World!" said a portion of the event text. "Join us in the untouched woodlands of the Sinnoh region where we found a mythical Volcanion! ... Explorer: 'B-boss! There it is! It's Volcanion!' Brandon: 'Oh! Get back! Look at those arm-like things growing out of its back! It uses those to suck in moisture to turn into a thick fog! If we stay here, we'll be trapped in the fog!' Explorer: 'That was a close one! Thanks for saving me, boss!' Brandon: 'Stay alert at all times! Don't forget your courage sensor!'"

If you paid attention, the name Brandon comes up multiple times, and Pokemon Omega Ruby and Alpha Sapphire fans have a theory as to who he might be.

One popular theory is that the Brandon in question is "Pyramid King Brandon," the Frontier Brain and chief of the Battle Frontier's Battle Pyramid.
