There might be a 'pokedex horror story' where the Pokedex starts to give out strange and menacing messages about an upcoming disaster related to Pokémon.

One of the popular characters might be the main Pokedex holder, who is often depicted as brave and curious. Another could be a rival Pokedex holder, adding some competition and drama to the story. Also, some of the Gym Leaders or Elite Four members from the original Pokemon series might make appearances and be popular in these fanfics as well.

Misty is also a character that shows up a lot. Her knowledge of water - type Pokemon can be combined with her role as a Pokedex holder. Fanfictions might explore her adventures in different regions, her encounters with new Pokemon, and how she uses the Pokedex to learn more about them.

There could be stories about the adventures of different Pokedex holders. For example, they might encounter rare Pokemon, explore uncharted regions, or face off against powerful villains.

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.
