You can develop Ash by highlighting his bond with his Pikachu in new ways. Maybe Pikachu gets sick and Ash has to find a rare cure, and Astrid helps him. This shows his caring side. For Astrid, give her a signature Pokemon that has a special bond with her. Describe how she trains it and how it reflects her character. You can also include how she and Ash learn from each other's training methods, which would develop both characters.
Ash is that energetic trainer we all know from Pokemon, always eager to take on new challenges and befriend more Pokemon. Astrid in Pokemon fanfiction can be seen as a fresh addition to Ash's world. She may be designed to add new dynamics to the story. Maybe she has a different approach to Pokemon training compared to Ash, like focusing more on Pokemon's natural instincts rather than just battle strategies. And she and Ash could start off not getting along but then gradually become good friends as they share experiences in the Pokemon world.
Ash could become more responsible as he has a unique starter that might need special care or training. He'd have to learn new ways to bond with it, which would make him more empathetic towards Pokemon in general. For example, if the starter is shy, Ash would have to be patient and gentle, thus developing his patience.
To develop the characters, give them unique goals and dreams. One might dream of becoming the best Pokemon trainer in the world, while the other wants to open a Pokemon sanctuary. Their relationship can grow as they support each other in achieving these goals. Also, show their flaws. No one is perfect. One could be a bit stubborn, and the other might be too trusting. These flaws can create conflict and make the story more interesting.
Ash could develop by learning from Sakura's more methodical approach to Pokemon. For example, he might start to study Pokemon habitats more carefully. Sakura, on the other hand, could become more adventurous like Ash, taking more risks in battles.
Often, it starts with Ash having an internal struggle or realization about his gender identity. He might notice that he doesn't feel like he fits the traditional male role he has been in. Then, he begins to explore this new side of himself, perhaps trying out different appearances or behaviors that are more in line with his true self.
At first, Meloetta might be shy around Ash. But as Ash shows kindness and respect for Meloetta's power and uniqueness, they start to bond. Ash could take Meloetta to different Pokemon contests or battles. Meloetta, in turn, uses its music to cheer on Ash's Pokemon. Over time, they become inseparable friends, relying on each other in tough situations and having fun together during their travels.
A more complex plot could be set in a world where there is a threat to all Pokemon. Ash and Astrid, along with their Pokemon friends, have to gather a set of ancient artifacts to save the Pokemon world. Along the journey, they have to overcome their own personal doubts and differences to succeed.
Ash could develop his character in Sinnoh by becoming more strategic in his battles. Since Sinnoh has a variety of strong and unique Pokemon, he'd need to think more carefully. Misty could develop by becoming more independent. Maybe she takes on some solo adventures in Sinnoh, away from Ash for a bit, and this helps her grow as a trainer.
Ash's character development could involve him becoming more empathetic towards Pokemon, influenced by Anabel's gentle nature with them. He could start to focus more on the well - being of his Pokemon rather than just winning battles. Anabel, on the other hand, could develop her leadership skills. With Ash by her side, she could take charge in more situations and grow in confidence. Their shared experiences, like getting lost in a new forest and having to rely on each other, would also shape their characters.
He could develop more patience. Since rare pokemon are often hard to find and catch, he would need to wait for the right moment. This could also teach him to be more observant of his surroundings and the behavior of pokemon. And his bond with his existing pokemon could also strengthen as they work together to catch the rare one.
