The main characters are Ash and Ashley. Ash is our familiar hero with his Pikachu by his side, always eager to catch more Pokemon and become a Pokemon Master. Ashley, on the other hand, can be anything from a fellow trainer who has a special connection with Ash, to a character with a mysterious past related to the Pokemon world. In some fanfics, she might have a rare Pokemon or a special ability that draws Ash to her and they embark on adventures together.
Obviously, Ash is a main character. In many fanfics, Pikachu is also a central figure, always by Ash's side. Sometimes, other companions from the anime like Brock or Misty might also be important characters in these fan - made stories, depending on the plot of the fanfic.
Team Rocket, of course. Jessie, James, and Meowth would see Ash as Ashley and might come up with new schemes to catch Pikachu. They could be completely thrown off by Ash's new appearance and behavior. Professor Oak could also play a role. He might be the one to figure out how to turn Ash back to his original form or provide some scientific explanations for the transformation. Another potential character could be Dawn. She could meet Ashley and be inspired by her unique approach to Pokemon training, which was originally Ash's but has a different flavor in Ashley's form.
One popular Pokemon Ash Ashley fanfic is 'Ash and Ashley's Unseen Adventures'. It takes the characters on a journey through unexplored regions in the Pokemon world, filled with unique Pokemon encounters. Another great one could be 'Ashley's Impact on Ash's Journey' which focuses on how Ashley changes Ash's perspective and approach in his Pokemon training.
Ash is often seen as the more action - oriented of the two. He could be the one who has special skills like combat or magic in some fanfictions. Ashley, though, has her own charm. She may be good at making friends, which helps them in their adventures. Their relationship can range from being just friends to having romantic undertones, depending on the direction the fanfiction author takes.
I think Gary would be a great addition. His rivalry with Ash could create some interesting storylines. He might start off as a bit of a antagonist but then end up being an ally. Also, Dawn could be included. She has her own unique style of training Pokemon and her friendship with Ash could be further explored in the context of Ashley being there as well. And then there's May, who could bring in her Contest experiences and help Ash and Ashley in different ways related to Pokemon showcases.
Well, it could be that the fanfic focuses on a parallel universe where Ash is magically turned into Ashley. This could lead to different storylines. Maybe Ashley (formerly Ash) has to deal with the different expectations that come with being a female in the Pokemon world. She might face new challenges in terms of how she is perceived by other trainers, and also how she interacts with female - only Pokemon groups or events.
Since it's an 'ash the pokemon fanfiction', Ash is the central figure. But it could also feature his friends from the original series like Misty and Brock. And of course, the villains he encounters would be important characters too. There may be new characters created by the fanfiction writer, such as a mysterious trainer who has a rare and powerful Pokemon that Ash has to face.
Obviously, Ash is one of the main characters. Since it's about him being a legendary Pokemon in this fanfiction, he's central to the story.
Obviously, Ash is one of the main characters. He's the protagonist who has a passion for pokemon and is always eager to become a pokemon master. And the legendary pokemon he encounters or befriends would also be important characters. For instance, if it's Lugia, Lugia would play a major role in the story as it's a very powerful and mysterious pokemon.
Ash is obviously one of the main characters. He is at the center of the harem concept. Then there would likely be a group of human characters who are part of his harem, though their specific identities can vary greatly depending on the fanfiction.
