Pokémon The Series: Sun & Moon

Tough Guy Trials!!! (21x30)

:

Team Rocket (especially Jessie) are celebrating getting a Z-ring and a Mimikyu Z-crystal, but they are shocked to see Ash, Pikachu, Rotom-Dex and Poipole arriving on Ula'ula Island. Ash is ready to undergo his third Island Trial, but first he has to find Island Kahuna Nanu. At the stationhouse, Nanu is in the middle of an unwelcome phone call from Giovanni when Ash arrives. Nanu pretends to be someone else and tricks Ash into looking after all of the Alolan Meowths while he sneaks away, and they nearly prove too much for Ash to handle, even with his Pokémon's help. After they all finally fall asleep, Acerola arrives and exposes Nanu as the Island Kahuna. At the Island Library where Acerola works, she tells Ash the legend of the Alolan Blinding One (which is overheard by Team Rocket). Finally, Nanu shows up and Ash begs to undergo the Island and Grand Trials. Although initially refusing, Nanu reluctantly agrees to a battle to see if Ash is skilled enough. It's Ash's Lycanroc versus Nanu's Krookodile, but Lycanroc is continually overpowered. Eventually, Lycanroc loses its temper again and is badly defeated. Despite the devastating loss, Ash is determined to stay on Ula'ula Island and train with Lycanroc to get stronger and overcome Nanu's Trials.
