Pokemon X and Y's three hidden in game Pokemon have not been fully uncovered yet, but one of them is set to be the star of the next movie hitting the franchise.

Diancie, Volcanion, and Hoopa were all uncovered by hackers as coding within the game. Upon the final release of X/Y these three were omitted, however, hackers were able to take the code and rework it to include them back in the game. There is no real information about them out yet, but now a Japanese publication, CoroCoro, features Diancie as the lead for the new film.

Serebii reported the movie will be called, Cocoon of Destruction & Diancie. The screen shot of the Pokemon can be seen in the magazine here.
