The Cocoon of Destruction & Diancie (Japanese: 破壊の繭とディアンシー,Hakai no mayu to Diancie) is the first Pokémon X and Y series and seventeenth Pokémon movie. It will be released in Japanese theaters on July 19, 2014.
It involves a Great Destruction that once wreaked havoc in the Kalos region, making life become extinction, a barren wasteland. The Destruction Pokémon, Yveltal is said to have been the cause of this horrific event. Once Yveltal destroyed all life in the region, it turned into a Cocoon of Destruction, in which he still lies in a dormant sleep. Opposing Yveltal was Xerneas, the Life Pokémon. Only to had the power needed to restore balance against Yveltal's destructive nature and restored life to both humans and Pokémon of Kalos.
