Since the winner gets to battle the Masked Royal and Incineroar in an exhibition match, the assumption is that Pikachu (and Ash) won.
In the Pokémon Sun & Moon anime, the Alola League is getting underway.
And Ash previously traveled back in time to talk to a young 5-year-old Professor Kukui, who went on to battle under the name the Masked Royal and found the Alola League.
Does this mean that Ash will actually win the Alola League?
