Maybe there's a plot where a werewolf pack is causing trouble in the wizarding world and Hermione, Fleur, and some other characters team up to deal with it. Along the way, Hermione and Fleur develop a special bond that goes beyond friendship. There could be elements of mystery, action, and romance in such a plot.
Another possibility is that Fleur, in a bid to gain more influence in the magical world, uses Hermione's research on some ancient magic without permission. When Hermione finds out, she realizes Fleur has been using her all along, and this is the ultimate betrayal. Hermione then has to find a way to expose Fleur's actions and clear her own name.
One plot idea could be a werewolf Death Eater who is forced to work with Hermione under some strange circumstances. Maybe they are both on a mission to retrieve a powerful magical artifact, and along the way, the werewolf starts to question his loyalty to the Death Eaters as Hermione shows him the value of kindness and justice.
Well, perhaps they form a secret society within Hogwarts that promotes dark magic. They recruit students who feel left out or who have a thirst for more power. Dark Hermione could use her knowledge of spells and Dark Fleur her charm and allure to draw in followers. And then there could be a conflict when the other students and teachers start to suspect something and try to stop them.
Another storyline could involve a werewolf character who is actually a misunderstood outcast. Hermione and Fleur could befriend this werewolf. For example, they might discover that the werewolf was wrongly accused of a crime. Hermione would use her logical thinking to prove the werewolf's innocence, and Fleur could use her social influence within the wizarding community to change people's views.
One plot idea could be that Fleur starts off subtly trying to befriend Hermione. She might invite Hermione to various Beauxbatons events under the pretense of cultural exchange. Then, as time goes on, Fleur becomes more possessive, getting jealous when Hermione spends time with Harry or Ron. Another idea is that Fleur discovers Hermione's unique magical abilities and wants to keep her close to learn from her and also have her all to herself. Maybe she tries to isolate Hermione from the Hogwarts crowd.
One idea could be that in a world where werewolves are more accepted, Hermione discovers Minerva was once bitten and becomes determined to help her during the full moon. She could research new spells to ease the transformation pain.
One common theme is acceptance. Hermione being a werewolf is not an easy thing in the wizarding world, and Fleur's acceptance of her is a big part of these stories. For example, in many fics, Fleur has to defend Hermione from those who would shun her.
What makes it unique is the way it can re - imagine the werewolf lore within the Harry Potter universe. With Hermione and Fleur at the center, the fanfiction can take the werewolf concept and twist it. Maybe they discover new ways to control the werewolf transformation, or they find a way to communicate with werewolves on a deeper level. Their relationship adds an extra layer of complexity to the werewolf stories, as they have different perspectives and experiences that can shape how they interact with werewolves.
