One popular example could be 'Beneath the Bruises'. In this fanfiction, Hermione gets hurt during a battle in the Forbidden Forest. The author vividly describes her pain and the reactions of her friends, especially Harry and Ron. It's a heart - wrenching read as they struggle to save her.
Perhaps in the fanfiction, Hermione gets even with those who underestimated her. She could expose their wrongdoings or secrets, using her skills in research and deduction. For example, if someone tried to take credit for her work, she'd find a way to prove it was hers and make them look foolish in the process.
Maybe it's a story where Hermione accidentally gets caught in the middle of a wizard duel gone wrong. One of the angry duelists punches her in a fit of rage. Then the story could focus on how she deals with the injury and the chaos that follows, as well as her pursuit of justice for the unprovoked attack.
One possible scenario could be during a battle at Hogwarts. Maybe the Death Eaters target her specifically, and she gets hit by a dark curse while trying to protect her friends. Another could be in an accident in the Forbidden Forest. She might be exploring and stumble upon some dangerous magical creatures, like a centaur gone wild, and get injured in the encounter.
One possible consequence could be severe pain for Hermione. Splinching is a dangerous and accidental form of Apparition gone wrong. She might have to endure physical trauma and need immediate medical attention. In the wizarding world, perhaps Madam Pomfrey would have to use a combination of spells to heal her. Another consequence could be emotional distress. Hermione is a very capable witch, and getting splinched could shake her confidence, making her more hesitant to use magic related to Apparition in the future.
One great fanfiction could be 'A Meeting of Minds' where Hermione and Remus meet in the Hogwarts library. Hermione is researching for a complex spell and Remus, being the knowledgeable wizard he is, offers his help. This leads to a series of conversations where they start to understand each other's perspectives on magic, life at Hogwarts, and their respective backgrounds. It's a slow - burn story that beautifully develops their relationship.
One possible fanfiction could involve Hermione being turned into an elf due to a misfired spell. In this scenario, she might struggle with the new form's limitations, like being shorter and having less physical strength. But, being Hermione, she would use her intelligence to adapt and find a way to reverse the spell. For example, she could search through ancient magical texts in the Hogwarts library to find a solution.
One possible reason could be that Hermione is too focused on her studies and career goals in the wizarding world. She might see a relationship with Harry as a distraction. Another reason could be that she has different values when it comes to love. Maybe she wants someone more like her, who is more into books and intellectual pursuits all the time, while Harry is more action - oriented.
Rather than focusing on this specific rather strange scenario, there are many great Hermione and Draco fanfictions that explore their relationship in more healthy and interesting ways. For example, some stories might focus on them becoming friends or allies, or having a more complex relationship based on mutual respect. So I would encourage you to look for those instead of this particular type of fanfiction.
A great plotline could be the mystery behind who turned Hermione into a baby. It could be a dark wizard trying to stop her from achieving something in the future. As a baby, Hermione might start showing some unusual magical abilities that she didn't have before, which could attract the attention of both good and bad forces in the wizarding world. And her friends would be in a race against time to protect her and find a way to turn her back.
