A fanfiction could explore a time - travel scenario where Hermione goes back in time and meets a young Sirius Black. This would be an interesting dynamic as Hermione already knows a lot about Sirius from stories, but now she gets to interact with him in his youth. She could try to prevent some of the bad things that happen to him later in life. However, this would also create a lot of potential changes to the timeline. Sirius might be initially suspicious of Hermione but soon realize that she has valuable insights and together they could try to change the course of wizarding history.
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.
There's a fanfic called 'Sirius and Hermione's Unbreakable Bond'. It starts with Sirius seeing Hermione's potential from the very beginning. He becomes a mentor to her, which is different from their normal Hogwarts interactions. The story delves deep into how their different experiences in the wizarding world bring them closer. Hermione's intelligence and Sirius' rebellious spirit create a unique dynamic between them.
Another aspect could be that Hermione sees Snape's past and the hardships he has faced. Maybe she stumbles upon some old memories of his in the library. This newfound understanding makes her more empathetic towards him. As a result, they start to communicate more and form an alliance of sorts, united by their love for Hogwarts and 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.
A simple plot could be that Hermione teams up with Peter Pan to rescue one of the Lost Boys who has been captured by pirates. Hermione's intelligence and Peter's bravery would make them a great team.
In the context of this fanfiction, Hermione might use her time - turning device (if allowed in the story) to assist Peter in preventing a crime before it even happens. Peter would be amazed by the magic and the possibilities it offers. They would need to work together to ensure that they don't disrupt the timeline too much while still achieving their goal of stopping the bad guys.
In another take on this fanfiction, Draco and Hermione accidentally fall into a magically - protected pool that has the power to make them relive their worst memories. As they swim in the pool, they are forced to confront their past actions and how they have treated each other. This shared experience of facing their demons could be the catalyst for them to start anew, with a more positive and understanding relationship as they emerge from the pool.
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.
Some Hermione Granger and Tom Riddle fanfictions focus on alternate universes. In these, the power dynamics between the two might be completely different. Maybe in one universe, Tom never turns to the dark side and he and Hermione become friends or even more. These alternate universes give writers the freedom to play around with the characters' personalities and destinies, creating a whole new world of stories.
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.
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.
