In fanfiction, Ash and Greninja might have all kinds of adventures in Alola. They could encounter new Pokémon species that are unique to Alola. Greninja could show off its skills in the new environment, impressing the local trainers. Maybe they'll participate in the Alola Pokémon League together and face strong opponents.
One possibility is that Greninja's presence in Alola causes a stir among the local Pokémon. Some might be curious, while others might be a bit intimidated by Greninja's strength. Ash could use this opportunity to teach the local trainers about Greninja's type and how to battle against it. And Greninja could also learn new moves or techniques from the Alola Pokémon, which would be really exciting in the fanfiction.
