Our heroes are all gathered at the Altar of the Sunne, along with all four of Alola’s Island Guardians. Lillie and Gladion ask the Island Guardians for help to rescue their mother, Lusamine, who has been taken through an Ultra Wormhole by a mysterious Ultra Beast. After Tapu Koko and the others perform a ritual, little Nebby evolves into the mighty Solgaleo—one of the Legendary Pokémon of Alola!

At Solgaleo’s invitation, the Pokémon School students climb onto its back. With the help of a new Z-Move, Solgaleo opens an Ultra Wormhole and carries them through, off to rescue Lusamine from the Ultra Beast!
