Pokémon the Movie: Volcanion and the Mechanical Marvel

Councillor Alva and Prince Raleigh of the Azoth Kingdom order the artificial List of Pokémon Magearna to be brought to the Kingdom after it is found in the Nebel Plateau, a place populated by Pokémon who have been abused by humans. The Mythical Pokémon Volcanion tries recovering Magearna, but has a band attached to its leg and is sent falling to a forest where Ash Ketchum and his friends, Pikachu, Serena, Clemont, and Bonnie are camping. Volcanion lands in Ash and friends' vicinity, and when they recover, Ash finds a second band attached to himself. Clement discovers the bands emit an electromagnetic force that binds Ash to Volcanion like a chain. Volcanion runs off, dragging Ash along with it.
