Pokémon - Season 21 Episode 44 : Filling the Light with Darkness! 2023

Professors Kukui and Burnet have a hard time getting up in the morning, and when Ash gets to school, he discovers that the adults in his friends’ lives are in the same boat! The Aether Foundation team has a theory, but they’re exhausted too, so Ash takes charge of the Ultra Guardians (now including Gladion) to investigate. The culprit seems to be something on the other side of an Ultra Wormhole, draining all the energy from the Ultra Auras. Our heroes track down the wormhole, and they’re excited to see the Legendary Pokémon Lunala emerge—but a mysterious and frightening creature is right on its tail!
