One popular fanfic could be about Gabrielle's adventures at Beauxbatons. Maybe she has a secret mission during the Triwizard Tournament that wasn't shown in the original books. She could befriend some new characters and they go on an adventure to find a hidden magical artifact.
Well, it could start with Fleur Delacour finding Harry in a vulnerable state. Maybe after a particularly difficult encounter with Voldemort. Fleur, being a strong and kind - hearted witch, decides to take Harry under her wing. She brings him to the Delacour family home in France. There, Harry would be exposed to a different wizarding culture. He might learn new spells and magical techniques that are unique to the French wizarding world. And he could form a close bond with Fleur's sister, Gabrielle, as they grow up together.
One great 'Percy Jackson and Fleur Delacour' fanfiction is 'The Meeting of the Demigod and the Veela'. It has an interesting plot where Percy and Fleur cross paths in a magical forest. The author does a wonderful job of blending the two different magical worlds together.
One common theme is friendship. Often, the OC and Fleur start off as strangers and gradually become good friends. They support each other through various challenges in the wizarding world.
In the fanfic, Fleur Delacour might have seduced you by creating a sense of mystery and intrigue around herself. Maybe she showed a vulnerable side that made you feel special and wanted.
In one fanfic, Gabrielle gets involved in an international wizarding competition that is not the Triwizard Tournament. This competition tests different magical abilities, and Gabrielle shows her courage and determination as she competes against some of the best young wizards from all over the world. It's a story of her growth and self - discovery.
There is no direct romantic or significant relationship between them. Fleur is more associated with Bill Weasley, and Ron is friends with Harry Potter and in a relationship with Hermione Granger. They are just part of the wider wizarding community where their paths cross in a general sense.
There's also 'Soul Mate Serendipity in the Potterverse'. This one takes a unique approach to the concept of soul mates. Fleur is at the center of a mystery that involves an ancient magic related to soul mates. The author does an amazing job of building the tension and creating a world within the Harry Potter universe that is both familiar and full of new surprises.
The theme of cross - cultural relationships also pops up. Fleur is from Beauxbatons and Harry is from Hogwarts. Fanfics might explore how their different magical educations and cultural backgrounds interact. For instance, Fleur might introduce Harry to some unique Beauxbatons magic, and they have to overcome cultural misunderstandings to be together.
Another idea for a fanfiction could be that Fleur Delacour's sister is a powerful witch in her own right but has a completely different approach to magic. While Fleur is all about grace and charm in her magic, her sister might be more into dark arts - not in an evil way, but in a way of studying it to understand how to combat it better. She could end up teaming up with the Trio (Harry, Ron, and Hermione) to fight against a new dark wizard threat at Hogwarts.
