Pokémon The Series: Sun & Moon

The Prism Between Light and Darkness! (21x45)

:

Although Lusamine is originally against the idea, the Ultra Guardians travel with Lunala to the other side of an Ultra Wormhole opened by Lunala, while Professor Kukui and Sauboh prepare to face Rocket-Dan's Matori Matrix and Wicke and Professor Burnet try to figure out UB: BLACK's connection to the Radiant One. The Ultra Guardians arrive on a dark world, where they are attacked by other Bevenom until Satoshi's Bevenom convinces them to stop. Agoyon. an evolved version of Bevenom, communicates with them by telepathy and explains that UB: BLACK, actually named Necrozma and who is the actual Blinding One, needs Solgaleo's power to revive this dark and dying world after a meteor strike had caused it to lose its power of light. Agoyon also reveals that Satoshi's Bevenom had gone on its own to find a new world where they could survive. Necrozma appears, still possessing Solgaleo and battling Lunala, but when Gladio tries to attack he is stopped by Satoshi, who says that he intends to save everyone, and Lilie and the other support Satoshi's plan: the four Z-ring holders will use their Z-Moves in a combined attack to release Solgaleo from Necrozma's absorption and to give Necrozma enough Ultra Aura to restore it. Meanwhile back in Alola, the Matori Matrix unleashes a Mega Bossgodora, which defeats Kukui's Warrgle and Sauboh's Sleeper and Foodin.
