I think Tails' personality would be a mix of his old self and some new elements. He would still be the tech - savvy character we know. But as a girl, he might be more in tune with his emotions. He could also become more diplomatic, trying to bridge the gap between male and female characters in the Sonic universe. For example, he might start to mediate disputes between male and female groups more often, using his new understanding of both sides.
A possible plot could focus on how Tails' daily life changes. As a girl, she might have to deal with different social expectations. Her hobbies and interests could shift slightly. For example, she might be more interested in certain types of fashion or more nurturing activities. Her relationship with Amy could also change, perhaps they become closer friends as they share more 'girly' things. And Tails' mechanical skills might be seen in a new light, as she uses them in a different way to solve problems in her new form.
The transformation would force Tails to re - evaluate her relationships. With Sonic, she might feel like she has to prove herself all over again. This could lead to a stronger bond as they overcome these new challenges together. Also, Tails' self - confidence would be tested. She might initially be shy or self - conscious as a girl, but through various experiences, she would grow into a more confident character, whether she stays as a girl or finds a way to turn back.
A third theme might be related to the challenges Tails faces in a world that is often more focused on male characters in the Sonic franchise. As a girl, she might have to fight against different types of discrimination or expectations, which could add depth to the story and show a different side of the Sonic universe.
Dr. Eggman could still be the main antagonist. Even if Tails turns evil, Eggman might see him as a threat to his own evil plans. He could try to stop Tails while also taking advantage of the chaos Tails is causing among Sonic and his friends.
First, you need to establish the reason for the transformation. It could be a magical spell gone wrong, or some kind of strange dragon - related phenomenon. Then, focus on how Hiccup adjusts to her new body. She'll have to deal with different physical abilities and limitations. For example, she might be physically not as strong as before, but more agile in some ways.
A fanfic could explore how Hiccup's transformation into a girl affects his friendships. Astrid might react in a complex way. At first, she could be jealous or confused, but then they could form a stronger bond. Also, Hiccup's father, Stoick, might have a hard time adjusting to his son becoming a daughter, which could add a lot of emotional depth to the story.
One possible scenario in this fanfic could be that Tony Stark, through some sort of magic or scientific experiment gone wrong, turns into a girl. This could lead to a whole new set of adventures and character developments. For example, his relationships with other characters like Steve Rogers (Stony) would be completely different. He might have to face new challenges in a different physical form, such as how society and his friends would accept him. Also, his own self - perception would change, and he'd have to re - evaluate his identity.
Characteristics can vary widely. Some fanfics may give her a more feminine sense of style while still keeping her mechanical and flying skills intact. She could be more empathetic, which leads to her being a better mediator between the often - bickering Sonic and other characters. In some, she may have a more delicate appearance but a strong will, much like the male version of Tails but with a different aesthetic.
Common themes in 'Tails turns into a werefox' fanfiction include adaptation. Tails has to adapt to his new physical form and the abilities that come with it. There may be a theme of isolation as well. If people are afraid of his werefox form, he could end up isolated from society. And then there's the theme of self - discovery. As he experiences life as a werefox, he discovers new aspects of himself, both good and bad, that he may not have known when he was just his normal fox self.
