Pokémon the Movie: Diancie and the Cocoon of Destruction

In the underground Diamond Domain, home to many Carbink, the Mythical Pokémon Diancie rules as their princess. The land is kept alive by the Holy Diamond, but it’s crumbling, and Diancie hasn’t yet mastered the power to replace it. While searching for the Legendary Pokémon Xerneas for aid, Diancie crosses paths with a gang of thieves who aim to seize its diamond-creating abilities-accidentally rousing the Legendary Pokémon Yveltal from its slumber in the process. With Yveltal now on a destructive path, Satoshi and his friends must help Diancie unlock its hidden strength, halt Yveltal’s chaos, and protect the Diamond Domain before it’s too late.
