It could also be for the sake of creating a unique storyline. By making Hermione a 'bad girl', it adds an element of surprise and can lead to interesting character development. For instance, she might start off bad but then learn and grow throughout the fanfiction, which is different from her usual positive portrayal in the original works.
Yes, it can be a common theme in some fanfiction. One reason might be that some authors want to explore different aspects of Naruto's character. They might think that showing him as a 'bad boy' can add an edgy or different dimension to his personality, making the story more interesting.
She could be rebellious. Maybe she doesn't follow the school rules as strictly as in the original books and is more likely to take risks.
It could also be that Hermione has a sense of propriety about the stories of her world. Fanfiction might distort or misinterpret events and characters in ways she doesn't like. For example, if a fanfiction portrays her friends in a negative or inaccurate light, she would likely stay away from it. And she may have a loyalty to the original stories and authors, and view fanfiction as a bit of a violation of that.
Another reason could be related to school work. If there are new rules in Hogwarts that she deems unfair regarding academics, like restrictions on library access or new grading systems that don't reward hard work properly. Hermione is all about learning and fairness in education, so this could really make her angry.
One reason could be differences in teaching methods. Hermione is a very studious and by - the - book student, and Snape has his own rather unorthodox and often harsh teaching ways. For example, in the official books, Snape is known for his sarcastic remarks towards students, and Hermione might not tolerate this in a fanfiction scenario. She could argue with him about how his teaching is not conducive to a positive learning environment.
Perhaps in the fanfiction, Hermione leaves Ron because of his jealousy issues. Ron has shown bouts of jealousy in the original series, and if that continued to be a problem in the fan - created story, it could be a major factor. For example, if Hermione started to gain more recognition in the wizarding community for her intelligence and contributions, and Ron couldn't handle it well. Or it could be that new characters were introduced in the fanfiction, and Hermione developed a stronger connection or friendship with them, which made her re - evaluate her relationship with Ron.
In fanfiction scenarios where Hermione is betrayed by the Order, it could be related to a prophecy. Maybe there is a prophecy that involves Hermione in a way that the Order misinterprets. They think that by betraying her, they are saving the wizarding world. Or perhaps there is a conflict of ideology. Hermione might have some new ideas or approaches to magic that the more traditional members of the Order oppose. And they see her as a danger to their established ways. Also, personal grudges among the Order members could spill over. If someone in the Order has a long - standing grudge against Hermione for some past incident, they could convince others to betray her.
One reason could be Hermione's intelligence. Snape might recognize that she is smart enough to understand his complex situation. He could see her as someone who could offer a different perspective on his problems.
One possibility is that the fanfiction presents unique plotlines involving Hermione. It could place her in different magical scenarios or make her interact with characters in unexpected ways. This novelty can be very appealing. Also, if the fanfiction develops Hermione's intellectual side further, showing her solving even more complex magical problems, that could also impress Rowlw.
One reason could be their different areas of expertise. Annabeth is highly skilled in architecture and battle strategies in the Percy Jackson world. Hermione, being a brilliant witch in the Harry Potter universe, might feel jealous if she perceives Annabeth as having more practical and hands - on skills. Another factor could be their relationships. If Annabeth has a really great relationship with someone Hermione admires or wishes to be closer to, it could stir up jealousy. For example, if they were in a shared universe and Annabeth was closer to Harry or Ron than Hermione was.
