Obviously, Ash (as a girl) would be the main character. Pikachu would still be by her side, being her loyal and cute partner. Her friends like Brock and Misty would also be important characters. Brock might be even more protective of her now, and Misty could become a sort of role model for her in some ways.
Professor Oak would still be an important character. He might have different reactions to Ash being a girl. He could be more cautious about sending her on certain adventures at first, but then see that she has the same capabilities as before and encourage her to continue her Pokémon journey.
Well, Pikachu would still be a main character. Since Ash, now as a girl, has Pikachu as her partner Pokemon, Pikachu would be right there with her on her adventures. Also, Misty could have a different dynamic with Ash as a girl. Maybe they become closer friends or even rivals in a new way.
Obviously, Ash is one of the main characters. He is the one on the journey to become a Pokemon master. Pikachu would also be a key character as Ash's loyal partner. There might also be Brock and Misty, his old friends, who could make appearances and help him out on his journey.
It could be a powerful and evil Pokemon trainer who wants to capture Ash in his new Pokemon form. This trainer might be after Ash because he believes that a human - turned - Pokemon has some special power or value.
Ash and Sabrina are the main characters. Ash, known for his journey to become a Pokemon master, is now in a position where Sabrina is under his control in this fan - made story. Sabrina, with her strong psychic abilities, is in a very different role than what we usually see in the regular Pokemon storyline. Their interactions and how they adapt to this new relationship would be the focus of the story.
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.
Pikachu would definitely still be there. It's Ash's most loyal companion, and it would be interesting to see how their relationship might change now that Ash is a girl. Maybe Pikachu would be more protective or show a different kind of affection.
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.
It could be a trainer who hates Pikachu and wants to capture all of them. This would put Ash, as a Pikachu fan, in direct conflict with this trainer.
It could be a trainer who has a dislike for Charmander. This trainer might see Ash's new - found love for Charmander as a threat and try to undermine Ash's relationship with his Charmander. For example, this antagonist could try to steal Charmander or set up difficult battles where Charmander is at a disadvantage.
The main characters are Ash and Lance. Ash is a well - known Pokemon trainer from the Pokemon series, always eager to learn and grow. Lance, on the other hand, is a powerful and respected figure in the Pokemon world.
