During the finals of the Pokémon World Coronation Series Masters Eight Tournament, Ash and Leon continue to enjoy their fierce battle! Noticing the match’s back-and-forth rhythm, Dawn points out that both Champions have similar battling styles. The battle action is as intense as can be. First, Leon’s Rillaboom takes down Ash’s Dragonite and Sirfetch’d, but Dracovish gets revenge. Then, Leon brings out Cinderace, who eliminates Dracovish. With Ash down to only Pikachu, Leon switches in his Charizard, who was his first partner Pokémon, just like Pikachu was Ash’s. After Gigantamaxing, Charizard attacks, while Ash and Pikachu counter with a Z-Move—and the combined power causes Eternatus to appear! But why?
