Well, it can change her relationships. For instance, she might be treated differently by male characters in the Muggle world compared to how Harry would have been. In romantic relationships, she may attract different types of partners. Maybe she'll have more female friends who she can bond with on a different level.
The gender change can influence her self - discovery journey. Fem Harry may have different insecurities and strengths compared to male Harry. She might struggle with body image or the expectations that come with being a female in both the wizarding and Muggle worlds. This could lead to a more complex character arc as she learns to embrace her new identity while still being true to her magical self.
She could use a magic - suppressing charm. This charm would make it so that her natural magical aura is hidden from other wizards and even from magical detection devices. For example, if a wizard were to pass by her with a magical detection spell active, they wouldn't sense her magic. Another way is by only using very basic and small - scale magic when absolutely necessary. Like if she needs to light a candle in a power outage, she might use a very tiny and discreet fire - making spell that looks almost like a normal match being lit.
Her gender can make her role more challenging. In a male - dominated wizarding world, as a female necromancer, she may face more opposition and skepticism. People might not take her seriously at first, thinking that necromancy is too dangerous for a woman. But it can also make her more unique and interesting. She might bring a different perspective to necromancy compared to male characters.
One common plot is that fem Harry uses her magic subtly in the Muggle world while trying to stay hidden. For example, she might use magic to fix small things in her Muggle apartment without being noticed. Another plot could be her making Muggle friends and having to constantly be on guard not to let her magical identity slip. She may also encounter other magical beings who are also hiding in the Muggle world and they form a sort of underground magical community there.
It changes the narrative by introducing a new layer of secrecy. Instead of the straightforward story of Harry as a male hero, there's now this hidden aspect that can affect every event. For example, duels might be different if opponents underestimate Harry thinking she's a girl.
One interesting plot could be that Fem Harry Potter uses her magic in very subtle ways in the Muggle world to avoid detection. For example, she might use a charm to make her schoolbooks seem like normal ones so that no one suspects she's studying magic. Another plot could involve her making friends with Muggles who have an inkling that there's something different about her, and she has to constantly dodge their questions while also protecting them from any magical threats that might come their way. And she might also be on the run from some dark wizards who are trying to find her in the Muggle world, so she has to keep changing her identity and location.
The story's plot could also take different turns. Instead of the usual challenges he faces as a male ninja, he now has to deal with issues related to hiding his gender. This could include things like disguising his appearance more carefully and avoiding situations where his gender might be discovered.
Her gender as a fem Naruto born as the Kyuubi might make Sasuke more protective of her. In the original, Sasuke was somewhat competitive with Naruto. But now, he could see her as more delicate, even if she has the Kyuubi's power. This could lead to a more complex relationship dynamic, with Sasuke being torn between his pride and his growing feelings for her.
Well, she could start by dressing in a more androgynous way. Maybe wearing loose-fitting clothes that don't give away her feminine shape. Also, she might try to lower her voice or use certain speech patterns that are more associated with males in that fictional world.
It can change the power dynamics. For instance, if there's a situation where the wizarding world needs resources from the Muggle world, Hermione's wealth can be a key factor. She could use her money to buy things that are scarce in the wizarding world.
The theme of heroism could be transformed. A female Harry Potter in the fanfiction might bring a different view of heroism. Instead of the typical male hero archetype, it could show that heroism is not gender - bound. This challenges the original story's perhaps more traditional view of the hero. Also, the theme of family might be altered. How Harry's new gender is perceived within the wizarding family structure could be a whole new exploration.
