Pokemon Ultimate Journeys: The Series Episode -23 Chasing to the Finish!

Chasing to the Finish! In the Galar region's Iron Ruins, Quillon confronts a Registeel, his Urshifu pummeling it into submission with Close Combat as he prepares an Ultra Ball. Meanwhile, at the Cerise Laboratory in Kanto, Goh receives a notification of the very last Project Mew Trial Mission. Of the two given options, he chooses the one that requires catching Regieleki and Regidrago. Professor Cerise tells Goh and Ash that they're two mostly unknown Pokémon somehow linked with the Split-Decision Ruins in the Crown Tundra.
