One great fanfiction could be where Sirius becomes a sort of mentor to Hermione's family. He could share his knowledge of the wizarding world's secrets, helping them understand Hermione better. For example, in a story I read, Sirius taught Hermione's parents about magical defenses, which was really interesting as it showed a different side of family interaction in the wizarding world.
A fanfiction might depict Sirius and Hermione as co - teachers at Hogwarts in an alternate universe. Sirius could teach Defense Against the Dark Arts in his own unorthodox way, and Hermione could bring in her academic knowledge. Their teaching styles would be very different, but they would complement each other. The students would be both fascinated and a bit intimidated by this pair. They would have to deal with things like classroom pranks and students who are having trouble with the coursework, all while building a unique bond.
One possible fanfiction could be about Sirius mentoring Hermione. Sirius has a wealth of knowledge about the wizarding world, especially the darker aspects. He could teach Hermione things that she wouldn't learn in the classroom. For example, he might share his experiences with the Dark Arts and how to defend against them in a more practical way than textbooks. Their relationship could start off rocky as Hermione is a rule - follower and Sirius is more of a rebel. But over time, they come to respect and learn from each other.
One common theme is the idea of defying the norm. Since their relationship is not part of the original story, it goes against what's expected. Another theme could be the exploration of time and its impact. For example, if Sirius somehow survives and meets Hermione at a different point in time. There's also often a theme of love that transcends boundaries, whether it's the age gap or their different social standings within the wizarding world.
Their interaction can also bring about emotional growth. Sirius, having lost his own family in many ways, can find a new sense of family with Hermione's. This can change his character arc, making him more stable and less reckless. And for Hermione, it gives her more support in the wizarding world. Her family now has someone like Sirius to rely on, which can change how she approaches problems. In a detailed fanfiction I read, Sirius' presence in Hermione's family made her more confident in exploring the darker aspects of magic because she knew her family had his protection.
There are quite a few out there. One interesting fanfiction might be on Archive of Our Own. You can search for tags related to Sirius Black and Hermione Granger. The storylines often explore unique relationships and interactions between the two characters that are not part of the original canon. However, the quality can vary greatly, so it's important to read reviews or summaries before diving in.
The contrast between their personalities. Sirius is wild and impulsive, while Hermione is studious and cautious. When combined in fanfiction, it creates an interesting dynamic.
There are quite a few good ones. For example, some focus on Sirius mentoring Hermione in the ways of the wizarding world outside of what she learned at school. This could include knowledge about the Marauders' era and secrets of Hogwarts that were long forgotten. The chemistry between their characters can be really interesting to read about in these fanfictions.
Well, perhaps there's a fanfiction where Sirius Black is wrongly accused again, but this time Hermione believes in his innocence from the start. She uses her intelligence and resources to prove his innocence while they are on the run from the Ministry. Along the way, they form a deep bond and discover new magical abilities within themselves that they use to clear Sirius' name and also make some changes to the wizarding world's justice system.
Sirius Black's adoption of Hermione Granger in fanfiction would likely have a profound impact on their characters. Sirius, who has been through so much pain and loss, would find new purpose in taking care of Hermione. He might become more nurturing and less reckless. Hermione, being the intelligent and inquisitive girl she is, would bring out a different side of Sirius. She would make him think more about the future and how to protect her. For Hermione, she would gain a new family, which could make her more empathetic towards those who have lost their families. Also, she might pick up some of Sirius's bravado and be more assertive in difficult situations.
