Pokemon the Movie 18: Hoopa and the Clash of Ages

A century ago, the power of a mighty creature known as Hoopa, who is capable of single-handedly defeating legendary Pokemon, was captured in a bottle by a lone traveler. The bottle was then hidden deep inside a cave in the desert, in the hopes that the darkness sealed within it would never see the light of day again.Years later, a young man finds the bottle and breaks the curses surrounding it, releasing the power confined within it. Its contents take the form of Hoopa's shadow, and it uses its unbound power to shatter the bottle and prevent anyone from capturing it again. The shadow then goes on a rampage and attacks the original Hoopa, while both Pokemon summon other legendary creatures to aid them in their brawl. Satoshi—a budding Pokemon trainer from the Kanto region—and his friends are caught up in the crossfire, and must now work to stop the ravaging Pokemon, or face a devastating clash of legends.[Written by MAL Rewrite]
