It would have a huge impact. For starters, Hermione's relationship with Harry and Ron would be re - examined. She might have different loyalties or secrets she's been hiding. Her skills and knowledge could also be related to her new heritage. For example, she might have an in - depth understanding of Regulus's knowledge of the Dark Arts, which could help in fighting Voldemort.
The impact could be seen in the way the wizarding world views Hermione. If she's Regulus's daughter, the pure - blooded families might react differently to her. Some might see her as a threat, while others might try to use her for their own gains. Her role in the fight against Voldemort could also change. She might have access to resources or information that only Regulus knew, which could turn the tide of the battle.
She might have access to unique Black family resources. For instance, she could find a hidden Black family library filled with dark arts books (which she would use for good, of course). This would give her an edge in her studies and in fighting the Dark forces.
If Hermione was James' daughter in fanfiction, Harry and Hermione's relationship would become more like a family one. They'd be closer in a different way, more like siblings.
One common theme is identity. Hermione has to grapple with who she really is, being the daughter of Regulus. Another is family secrets. Discovering that she is Regulus' daughter means there are likely many things she doesn't know about her family. And then there's the theme of legacy, as she has to decide how to carry on Regulus' name and any unfinished business he might have had.
In this fanfiction concept, it could lead to a whole new set of character dynamics. Hermione's intelligence could be seen as an inheritance from the Black family's cunning. For example, she might discover some long - lost Black family magic that helps her in her adventures at Hogwarts. It could also create interesting interactions with Sirius Black, who was Regulus' brother. Maybe Sirius would be initially shocked but then grow to be very protective of Hermione.
In her family relationships, it could be very tumultuous. Her mother might have to come clean about her father's past. Hermione might also have to deal with extended family members who might be involved with the Death Eater ideology. This could lead to Hermione cutting ties with some of her family in order to uphold her own values.
The plot would be drastically different. Hermione's presence in the Malfoy family could potentially change Narcissa's actions. Maybe Narcissa would be more hesitant to follow Voldemort's orders because she doesn't want to put her daughter in danger. This could also lead to a different ending for the wizarding war, as Hermione could use her influence within the Malfoy family to sway things in a different direction.
If Hermione were Regulus's sister in fanfiction, it would likely lead to a different kind of relationship with Sirius. Instead of just being friends with Harry who is related to Sirius, she would have her own family connection. This could also mean that she might have some knowledge about the family's dark past that Sirius didn't share with her in the original story, which could be used to her advantage in various situations.
Yes, there are some interesting ones out there. Some fanfictions explore how Hermione's life would be different if she was Regulus' daughter. They might incorporate her natural intelligence as being a trait passed down from Regulus. These fanfictions often create new storylines within the wizarding world, such as how she discovers her true heritage and how it impacts her relationships with other characters like Harry and Ron.
One way this could be possible in fanfiction is through some creative plot twists. Maybe there was a hidden relationship between a relative of Hermione and Regulus. It could involve time - traveling magic that somehow altered the family lines. Another idea is that there was a secret adoption or a magical protection spell that connected Hermione to Regulus in a family - like way.
In a fanfiction where Hermione is Tom Riddle's daughter, the storyline would be turned upside down. The prophecy about Harry and Voldemort might need to be re - evaluated as Hermione's connection to Voldemort could potentially change the balance of power. Her relationships with other characters would be complex. For example, Dumbledore might have had a different plan all along if he knew about Hermione's true parentage. The Death Eaters could also try to recruit her, seeing her as a way to get closer to Voldemort. This would create a whole new set of conflicts and challenges for Hermione, Harry, and Ron, and would lead the story in a completely different direction from the original.
