One common theme is the exploration of characters' growth. For example, if Hermione is paired with a less - likely character like Crabbe or Goyle in some fanfics, it shows how they can all grow and change through their interactions. Another theme is breaking stereotypes. When she's paired with a Slytherin like Blaise Zabini, it challenges the usual Gryffindor - Slytherin animosity.
Another theme is the discovery of new aspects of the characters. When paired with Neville in fanfiction, Hermione might see his hidden strength and courage in a new light, and Neville might see Hermione's vulnerability which wasn't as obvious in the original story. This helps in character development in the fan - created scenarios.
Some fanfiction also pairs Hermione with Neville Longbottom in rather unusual scenarios. Maybe in a world where Neville has developed some extraordinary magical abilities that Hermione is intrigued by, and they end up going on adventures together, exploring new spells and magical mysteries.
Self - discovery is also a theme. Hermione often has to learn more about herself, her limits, and her potential in fanfiction. For instance, when she is faced with a new magical ability or a difficult moral choice, she has to look inward and figure out who she really is and what she stands for.
Another theme is self - doubt. Given Hermione's usually confident nature, when she's depressed, she starts to question everything about herself. Her intelligence, her worthiness as a friend, and her place in the wizarding world. In some fics, she might even consider leaving Hogwarts because she feels she no longer belongs.
One common theme is friendship. When Hermione is injured, it often shows how Harry and Ron (and other friends) rally around her. For example, they might drop everything to find a way to heal her or protect her from further harm. Another theme is her own strength. Even when injured, Hermione usually shows great mental fortitude, like in fanfics where she continues to study or help others despite her pain.
Hermione and Captain America. Steve Rogers values honor and loyalty, and Hermione has those traits too. In a crossover, they could fight against a common enemy that is trying to take over both the wizarding world and the non - magical world. Hermione could use her magic to help Captain America in battles, and he could teach her about physical combat and strategy.
The pairing of Tom Riddle and Hermione is unusual because they are from different time periods and have very different outlooks on magic. However, in fanfiction, it can work because it allows for exploration of how Hermione's strong moral compass could interact with Riddle's early, pre - Voldemort self. For example, she could introduce him to new ways of thinking about magic that don't involve domination.
Some fanfictions pair Hermione with Draco Malfoy in rather unexpected ways. These stories usually involve a redemption arc for Draco and explore how Hermione, with her strong moral compass, could be attracted to a reformed Draco. It often shows a complex relationship development that goes against their initial enmity in the original series.
Friendship is also a big theme. Hermione's relationships with Harry and Ron are often explored in different ways. For example, how they support each other during difficult times at Hogwarts.
One common storyline is Hermione using the Time Turner to prevent a major disaster in the wizarding world. She might go back in time to stop a dark wizard from getting a powerful artifact.
