A young athlete whose running days might be behind her, a compulsive liar, a shy researcher, a bitter old woman, and a little girl with a big secret—the only thing they have in common is the annual Wind Festival in Fula City. The festival celebrates the Legendary Pokémon Lugia, who brings the wind that powers this seaside city. When a series of threats endangers not just the festival, but all the people and Pokémon of Fula City, it’ll take more than just Satoshi and Pikachu to save the day! Can everyone put aside their differences and work together—or will it all end in destruction?

One peaceful day on Earth, two remnants of Frieza's army named Sorbet and Tagoma arrive searching for the Dragon Balls with the aim of reviving Frieza. They succeed, and Frieza subsequently seeks revenge on the Saiyans.

After the defeat of Majin Buu, a powerful God of Destruction known as Beerus searches for the Saiyan warrior who defeated Frieza. Realizing the threat Beerus poses to Earth, the Z-fighters must stop him. Only Goku, humanity’s last hope, can ascend to the level of a legendary Super Saiyan God and save the planet, and possibly the entire universe!

Pikachu and Piplup bump into Gizamimi Pichu and Smoochum and lose the "sparkle" as a result. They must find the "sparkle" before Meowth's troop get their hands on it.
