One idea for a fanfiction could be that Ash travels to Kalos with his Infernape. There, Infernape discovers new moves or abilities inspired by the Kalos environment. It could be something related to the fairy - type energy prevalent in Kalos, which gives Infernape an edge in battles against certain opponents.
It could be about a Pokémon trainer who has some kind of special power or experience that makes them feel invincible in the Pokémon world. Maybe they have a super - rare Pokémon with extraordinary abilities or they've discovered a new training method that gives them an edge over others.
Well, a simple fanfiction could be that Ash's Infernape gets lost in Kalos and has to find its way back to Ash. Along the way, it meets different Kalos Pokemon and learns about their ways of life. This could be a cute and adventurous story.
There might be an experienced Pokémon trainer who has seen it all but then gets a new Pokémon or a new power that makes them feel invincible. This trainer could be the main character who then uses their new - found strength to protect the Pokémon world from a new threat, and along the way, they meet other characters who either help or hinder their journey.
