Lillie can touch Pokémon again! While our heroes celebrate, a disgraced Faba is determined to prove himself to Lusamine by summoning an Ultra Beast—the same one that threatened Lillie years before. He kidnaps Nebby and convinces it to teleport him into his research lab at Aether Paradise.
Ash, Gladion, Lillie, and Lusamine go after Faba, arriving just as a panicked Nebby transforms into a chrysalis and the Ultra Wormhole begins to open! The Ultra Beast known as UB-01 Symbiont emerges and attacks Lillie—but Lusamine throws herself in front of her daughter, and the Ultra Beast engulfs her instead and takes her back through the wormhole!
