In terms of her relationship with Draco, it could take an unexpected turn. With Remus as her father, she might be more empathetic towards Draco's family situation, considering the Malfoys' views on werewolves. This could lead to a more complex relationship between them, rather than just the typical rivalry. It could also change how she views Snape, knowing that Snape had a complex relationship with her 'father' Remus.
Well, if Hermione was Remus's twin sister in fanfiction, it could change a lot. For one, Hermione's intelligence could be tied to her werewolf heritage in some new and interesting ways. Maybe she'd use her knowledge to find a better way to deal with Remus's lycanthropy. Also, her relationship with Harry and Ron might be different as she'd have this whole other family connection to consider.
Well, if Hermione was Remus Lupin's sister in a fanfiction, it would change the story in many ways. For one, Hermione would have a different family background. She might grow up with knowledge of the wizarding world in a different way, as Remus is a werewolf and that would bring a whole new set of experiences and challenges to her family life. Also, her relationship with Harry and Ron could be affected. Maybe they would be more cautious around her, knowing she has a connection to a werewolf. It could also change the way she approaches her studies, as she might have learned some things from Remus before coming to Hogwarts.
Her relationship with Harry and Ron would be severely tested. They might be initially shocked and distrustful. Harry, who has faced his own dark - side related issues, could be more understanding but still cautious. Ron, on the other hand, might be more openly skeptical and afraid of what Hermione could become. It would take a lot of effort on Hermione's part to regain their trust.
If Hermione was Sirius Black's daughter in fanfiction, it would completely transform her character arc. She would have a different family history to grapple with. The stigma of being a Black might be added to the one of being a muggle - born in the eyes of some. But it could also give her more power and influence within the wizarding world. And Sirius would have a stronger reason to fight against Voldemort, not just for his friends but for his daughter.
Well, if Hermione was Yaxley's daughter in a fanfic, it would completely turn the original story on its head. Hermione's character, who was originally a Muggle - born witch and a firm ally of Harry and Ron, would now have a very different background. Her loyalties might be questioned, and she could potentially be in a position where she has to choose between her new - found family connection and her friends. This could lead to a lot of internal conflict within her character.
If Hermione was Remus' sister, her relationship with Harry and Ron would be affected. Harry might view her in a new light, as she now has a connection to one of his former teachers. Ron might be a bit jealous at first, but then realize it doesn't change who Hermione is. And her relationship with the other Hogwarts professors would also shift, as she has a closer family tie to Remus.
Well, if Hermione was Fenrir's daughter in fanfiction, it would completely turn the story upside down. For one, Hermione's character would have a whole new backstory of being part - werewolf. Her relationships with other characters like Harry and Ron would be different. They might be more cautious around her at first, fearing her werewolf side. And her academic achievements at Hogwarts could be overshadowed by the stigma of her father. Also, the way the wizarding world views her would change, as Fenrir is a feared werewolf.
In the realm of fanfiction, the idea of Hermione being Sirius and Remus' daughter might stem from a desire to explore different family dynamics. It could start with a time - traveling incident where the past is altered. Sirius and Remus might have found a way to ensure Hermione's existence in a different timeline. This would completely change the relationships in the Harry Potter universe and open up new storylines for the author to explore, like how Hermione would grow up with two very different fathers, one a werewolf and the other an escaped convict in the eyes of the wizarding world.
Well, in a fanfiction, anything can be made possible. Maybe it could be through some sort of magic gone awry. For example, a spell that was meant to protect Hermione's real parents ended up warping reality and making her seem like Remus and Sirius' daughter. Another idea could be that some dark wizard had a plan to manipulate their genes or magical essence in some way to create this new family connection.
With Harry, their friendship could also shift. In the original, Hermione's Muggleborn status was part of her identity that Harry respected. If that changes, they might become closer in different ways. For example, if Hermione is from a powerful pure - blood family, she could use her family's resources to help Harry in his fight against Voldemort more directly. Their relationship could become more of a strategic alliance in addition to a friendship.
