If Ash becomes a female in the fanfic, his relationships with his Pokemon friends would also be different. His Pokemon might sense the change and some could be more affectionate, while others might be a bit confused at first. Regarding his human friends, his relationship with Gary would take an interesting turn. Gary might be more intrigued by this new Ash and could either be more competitive or try to help her adjust. And when it comes to Professor Oak, he might be more fatherly or have different expectations of Ash now that she is female, perhaps expecting her to focus on different aspects of Pokemon research or training.
When Ash turns into a female, her relationship with Team Rocket would be quite different. Jessie and James might not take her as seriously at first, thinking a female trainer would be easier to defeat. But as they interact more, they could find that this new Ash is just as tough if not tougher. Her relationship with other gym leaders would also change. Some might be more chivalrous towards her, while others might be more critical, thinking that the change in gender might have affected her battling skills. Also, among the younger trainers, she could become a role model for female trainers, inspiring them to be more confident in their Pokemon training journey.
If Ash were to turn into a Pokemon in a fanfic, his personality would surely be affected. He's used to being in control as a trainer, but as a Pokemon, he'd have to learn to follow others' commands or work within a group. His once outgoing and friendly nature might become more cautious. He'd have to be more aware of predators and threats. And his competitive spirit might take on a different form. Instead of competing in trainer battles, he'd be competing in Pokemon - on - Pokemon battles, which could make him more aggressive or strategic depending on the Pokemon he turns into.
Well, with Sasuke, their relationship would become more of a protective - protectee one. Sasuke, who usually has a rivalry with Naruto, would now feel responsible for protecting this baby Naruto. With Sakura, she would be more motherly towards him. She might be the one constantly fussing over him, making sure he's clean and fed.
His relationship with Pikachu would be very different. They'd be more like equals now. Pikachu might even feel the need to protect Ash more. With his other Pokemon, they might be confused at first but then develop a stronger bond as they realize it's still Ash inside.
His relationship with Sasuke could become more complex. Sasuke might be both envious of Naruto's new power and also worried about Naruto losing his humanity in the dragon form. Sakura could be initially scared but then determined to help Naruto control his form, which would strengthen their friendship. His relationship with Kakashi would change as Kakashi would now have to mentor Naruto in a different way, guiding him to use his dragon powers for good and not let them consume him.
His Pokémon might be really confused at first. They're used to Ash as a human, so seeing him as a Pikachu would be quite a shock. But some of them, like Pikachu himself, might feel a closer bond since Ash is now in a similar form.
His relationship with Sasuke would be very different. Sasuke might be more protective of Naruto as a little girl. He may not see her as the same rival he once did and instead feel a need to safeguard her.
Harry's relationship with Lupin would be very interesting. Lupin, being a werewolf himself, could act as a mentor to Harry. He could teach Harry how to control his werewolf side better. And this shared experience could bring them closer together. But at the same time, Harry might feel a sense of resentment towards Lupin, thinking that Lupin could have prevented his transformation in some way.
His relationship with Annabeth would be really different. She would have to adjust to this new form of Percy. At first, she might be a bit scared or unsure, but then she would start to see the advantages of his dragon form and work with him. For example, she could use his ability to fly to reach places faster.
His relationship with Naruto would likely change. Naruto might be more protective of Neji as a girl, seeing her as more vulnerable. He could also be a bit more awkward around her at first. With Hinata, they might become closer as girls and share different kinds of secrets. And his former male rivals might either be overly competitive in a different way or start to develop feelings for him, which would create a very different dynamic.
Well, with Kakashi, he might be more cautious in how he trains Sasuke. As a girl, Kakashi might have to consider different aspects of training, like physical limitations that might come with the female form. His relationship with his clan members, if they were still around, could also be different. They might have different expectations of a female Sasuke. And when it comes to the other male ninja in the village, some might be attracted to him, which would create some awkward or interesting situations.
