Yes, there are likely fanfictions out there with such a plot. Fanfiction writers often come up with creative and alternative family relationships for characters. They might explore how Hermione's story could be different if Regulus were her father, perhaps delving into how her magical abilities or her place in the wizarding world might be affected by this new family connection.
Hermione in these fanfictions can be a bit of a maverick. She might break some rules to get to the truth about Regulus. Her loyalty to her friends is still there, but she's also driven by a need to uncover the mystery around him. She's not afraid to question the status quo of the wizarding world's view of Regulus. And she's always learning, adapting to new situations that arise from her interactions with him, whether it's about ancient magic or the politics of the wizarding families.
Fanfiction.net is also a good place. There are many different fanfics on there. However, the tagging system might not be as refined as AO3, so you may need to do a bit more sifting through the results to find the good Hermione and Regulus ones.
There's also 'A Different Kind of Magic'. In this fanfic, Hermione discovers a hidden diary of Regulus which leads to an adventure where they form an unexpected alliance. It's full of mystery and character exploration.
One great Hermione and Regulus time travel fanfiction is 'A Time to Heal'. It beautifully weaves their stories together as they navigate through different time periods. The author does an amazing job of character development, making their relationship seem very natural.
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.
Well, it's because they are two very interesting characters from different generations. Regulus is this mysterious figure from the past with a complex backstory, and Hermione is a brilliant, modern - day witch. Combining them creates a unique dynamic that fans love to explore.
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.
They both are strong - willed characters. Hermione is not one to back down in the face of challenges, and Regulus, despite his wrong choices, had the courage to go against Voldemort in the end. In fanfiction, their strong personalities can lead to intense interactions. They can clash at first due to their differences but then gradually grow to understand and respect each other, creating a really engaging relationship to read about.
Hermione is a Muggle - born witch who is highly intelligent and a strong advocate for justice. Regulus, on the other hand, came from a pure - blood family with a dark past. In fanfiction, this contrast allows for some really deep exploration. Their relationship can be a way to bridge the gap between different wizarding ideologies. Hermione can introduce Regulus to new ways of thinking, and he can show her the inner workings of the old pure - blood society. It's this clash and potential harmony that makes the pairing so interesting.
