Pokémon the Movie: Hoopa and the Clash of Ages

A hundred years ago, a solitary traveler sealed away the power of Hoopa-a fearsome creature strong enough to defeat legendary Pokémon single-handedly-inside a bottle. The bottle was hidden deep within a desert cave, meant to keep its dark power locked away forever. Years later, a young man stumbles upon the bottle and breaks its curses, freeing the power inside. The unleashed force takes the form of Hoopa's shadow, which destroys the bottle to ensure it can never be trapped again. The shadow goes berserk, attacking the original Hoopa, and both Pokémon call upon other legendary creatures to join their battle. Caught in the middle of this chaos is Satoshi, a Pokémon trainer from Kanto, and his friends. Now they must find a way to stop the rampaging Pokémon before the clash of legends leaves destruction in its wake.
