Episode Title:
From Z to Shining Z!.
Episode Description:
As the Alola Pokémon League’s exhibition match nears its conclusion, Tapu Koko appears—it wants to team up with Professor Kukui and battle Ash! Our hero responds by sending out Naganadel, and the clash of Island Guardian and Ultra Beast powers is an amazing sight. But Tapu Koko manages to overpower Naganadel, so Ash turns to Pikachu, his last Pokémon standing! Tapu Koko raises the stakes as it and Professor Kukui unleash a legendary Z-Move reserved for Island Guardians, but Ash and Pikachu rise to the challenge with their own Z-Move: 10,000,000 Volt Thunderbolt! Once the dust clears, Tapu Koko falls, and Ash and Pikachu are victorious!
