Here's What The Next Pokemon Movie Is About

Pokémon fans will soon have another chance to catch 'em all.

Earlier this year, The Pokémon Company announced an upcoming film centered around the pocket monsters. Entitled Pokémon the Movie 20: I Choose You, the flick will feature franchise favorites Ash and Pikachu in the very beginnings of their iconic friendship. Ash will don his classic costume and the pair will come across the legendary Pokémon Ho-Oh, just as they did on their first day as partners.

Additional plot details were left a mystery, but The Pokémon Company unveiled a second trailer and a full synopsis for the movie. In the trailer, fans can see Ash and Pikachu join forces with two other trainers that have Pokémon Diamond and Pearl-era Pokémon as their companions. The six band together to find Ho-Oh, becoming the "Heroes of the Rainbow" on their journey. By the looks of the trailer, the events of I Choose You take place before everyone's favorite boy and electric rodent become true best friends.

Here's the official plot summary for I Choose You (via Serebii): "Ash, a boy living in Pallet Town, greeted the morning of his tenth birthday, the day he could become qualified to become a Pokémon Trainer. Ash's heart was filled with a desire for Pokémon he has never seen before and a world he has never seen before, but while he was meant to be given a Pokémon that would become his partner at the Oak Laboratories, he ended up severely oversleeping, and all that was left for him was a single Pikachu, a Pokémon that did not get attached to humans. 'Do you hate me? I like you!' Even though the two were at odds with one another, their friendship deepened little by little, and as they looked up at the legendary Pokémon Ho-Oh that flew through the sky on the day they set off, Ash and Pikachu swore an oath as they held one of its Rainbow Wings: 'Let's go meet it together one day!' And thus, Pikachu and Ash, who set off on his journey to become the world's greatest Pokémon Master, end up meeting the Trainers Makoto and Soji on their way before getting told a legend concerning Ho-Oh."

Ash and others end up getting guided by Marshadow, a mysterious Pokémon that had been lurking in Ash's shadow without anyone realizing, and make their way to Mount Tensei, where Ho-Oh lives, but a strong opponent appears before them. Will the duo manage to reach Ho-Oh? In order for them to fulfill the promise they swore on the day the departed, the two of them now begin an adventure that will last until they become 'true partners!'"

Pokemon the Movie 20: I Choose You is, of course, the 20th installment in the Pokémon film franchise. It's set to hit Japanese theaters on July 15, and we'll update you on international availability as news breaks. In the meantime, check out how Pikachu has changed over the years.
