New Pokémon?

Notes:

Sauce: http://serebii.net/
Following the surprise appearance of what may be a new Pokémon and/or form, more people have been able to see the movie, Hoopa & The Clash of Ages and due to this, thanks to another friend of mine, we have a far more accurate sketch of it now which differs slightly from the original ones we had yesterday. It includes elements that were lost previously on it including a red stomach. Of course, there is still likely to be some discrepencies between the sketch and the actual design but this is a close approximation. Also, the massive Pokémon shown in CoroCoro that's also in the trailer has pulsating hexagons in the trailer around its body. It's not currently known when these Pokémon/forms will be completely revealed with official art and screenshots, but when it is, we'll post it here as soon as it comes.
