Well, Sonic is known for his agility and speed. In the Pokemon world, if he were to turn into a Pokemon, his speed would still be a major factor. However, it would be combined with the unique abilities of the Pokemon species. For instance, if he turned into a Geodude, his speed would be used in a more earth - based way, like quickly burrowing underground or rolling at high speeds. His jumping ability might also be affected, depending on the Pokemon form. He would also have to learn to use Pokemon - specific moves, which would be a new challenge for him.
His speed might become more of a stealthy movement. Since vampires are often associated with being sneaky, Sonic could use his speed to silently move around, like a shadow. Also, he might gain the ability to hypnotize enemies, which he could use to stop bad guys in their tracks before using his speed to quickly deal with them.
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.
The story would become more about Ash adapting to his new form. He'd have to learn how to move, eat, and sleep like a Pokemon.
In this fanfiction scenario, Sonic's personality could have some interesting shifts. Sonic as a girl might be more likely to rely on her wits and intelligence in a different way. Maybe she'll use her charm and quick thinking to outsmart villains instead of always relying on her speed. Her sense of humor could also change a bit. She might use more self - deprecating humor or be more sassy. And when it comes to relationships, Sonic could be more open and communicative. For example, she might have deeper conversations with Amy Rose about their feelings and experiences, whereas before as a male Sonic, he was a bit more reserved in that regard.
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.
Inuyasha's relationship with his enemies would also change. Some enemies might underestimate him in his baby form, not seeing him as a threat. However, some might see it as an opportunity to get rid of him once and for all. His friends would have to be extra vigilant in protecting him. And as Inuyasha grows up again in the story, his relationships with his friends would be different because of this experience. They would have a shared memory of taking care of him when he was at his most vulnerable, which could deepen their loyalty and friendship.
His relationship with Kagome would change significantly. Kagome might see Inuyasha in a new light, perhaps more as a sister - like figure at first, but then as she gets used to the new form, there could be a shift in their romantic undertones. With Miroku, Miroku would be more respectful in a different way. He might be less likely to tease Inuyasha in the same way he did before. Sesshomaru, on the other hand, might initially be disgusted or confused by his half - brother's new form, but it could also lead to some interesting developments in their rivalry as Sesshomaru tries to figure out if this new Inuyasha is still a worthy opponent.
In a fanfiction where Issei turns into a dragon, his relationships would be in flux. His relationship with his mentors or those he looks up to might change as they now see him as a different kind of being. They might treat him with more caution or more respect depending on how they view dragons. His friendships with his peers would also be altered. Some might see him as a weapon to be used in their battles or struggles, while others would see him as a friend in need of support. Romantically, if he had feelings for someone, that person would have to deal with the fact that Issei is no longer fully human. There could be jealousy from others who might want to be with the powerful dragon - Issei, or there could be newfound admiration from those who previously overlooked him.
His personality might not change completely. He'd still be the intelligent and laid - back person he was. But he might become more empathetic. Since he's now in a female body, he could better understand the struggles that girls face, which could make him more sensitive to others' feelings.
Dipper's personality change could be quite complex. Since he's now a girl, he might feel more pressured to conform to certain standards. This could make him initially more reserved. But as he gets used to it, his adventurous spirit could shine through in new ways. He might start to approach mysteries from a different perspective, one that combines his old way of thinking with the new insights he has from being a girl. He could also become more protective of those he loves, as he now has a different understanding of vulnerability.
