Pokémon: Hoopa—The Mischief Pokémon

A series of six anime shorts for the XY series, leading up to the release of Hoopa and the Clash of Ages. They star Ash Ketchum and his Pikachu as they deal with trouble started by the Mythical Pokémon Hoopa. The shorts originally aired weekly on Oha Suta from April 23, 2015 to May 28, 2015. English versions of all six shorts were available on Pokémon.com starting on December 11, 2015.

When Ash, Pikachu, and their friends visit a desert city by the sea, they meet the Mythical Pokémon Hoopa, who has the ability to summon things-including people and Pokémon-through its magic ring. After a scary incident, they learn a story about a brave hero who stopped the rampage of a terrifying Pokémon long ago. Now, the threat that has been bottled up for years is in danger of breaking loose again! Can Ash help his new friend overcome the darkness within...or will a dangerous secret erupt into a clash of legends?

The Pokémon Company streamed the "Mega Special Animation" short inspired by the upcoming Pokémon Omega Ruby and Pokémon Alpha Sapphire games on Sunday. The short features Pokémon undergoing the newly discovered Mega Evolution and Primal Reversion in the Hoenn region.

A short which ran along side the Pokemon XY: Hakai no Mayu to Diancie movie.
