Episode 48: Z-Move Showdown!

Overview

Just as Ash is crowned Champion of the Alola Pokémon League, an Ultra Wormhole opens above the stadium, and an angry Guzzlord appears! Ash had battled it previously in a parallel world, so he tells Alola’s island kahunas about the Ultra Beast’s weak spot. But before they know it, two more Guzzlord appear! The kahunas and Pokémon School class leap into Z-Move action to defeat the first two, while Ash, Pikachu, and the Masked Royal reunite with Naganadel—formerly Poipole—and use Gigavolt Havoc to send the third one packing. The resulting explosion blows off the Masked Royal’s mask, revealing his true identity: Professor Kukui!
