A typical theme is the power of love across time. In these fanfics, Harry and Fleur's relationship defies the normal flow of time. Their love, whether it's a slow - growing affection or a sudden attraction, is often what drives the story. Additionally, there's the theme of self - discovery. Harry may learn more about his own capabilities and desires through his interactions with Fleur in a different time. And of course, magic is always a central theme, especially the use of time - travel magic and how it affects their relationship and the world around them.
I'm not sure of the exact title, but there's a fanfic where Harry travels back in time and meets Fleur during the Tri - Wizard Tournament. He realizes that she has a different side to her that no one else has seen. Their relationship develops as they help each other out in various tasks, and it's a really sweet and exciting read.
In many fanfics, Fleur is often depicted as strong - willed. She's a Veela, so she has that alluring quality, but she's also smart and not just a pretty face. For example, in some fanfics she uses her Veela charm in a strategic way to get what she wants or to protect others.
In some fanfictions, Harry Potter might help Fleur by using his knowledge of magic. For example, if Fleur is in a dangerous situation during a wizarding tournament task, Harry could share some of his unique insights on how to overcome the magical obstacles, having experienced similar challenges himself.
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.
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.
Well, perhaps Fleur rejects Harry for some reason. Maybe she's still in love with Bill and tells Harry she can't be with him. This would leave Harry heartbroken as he might have developed deep feelings for her.
He might become withdrawn. Harry has been through a lot in his life, and being heartbroken by Fleur could make him retreat into himself. He may avoid his friends and isolate in his dormitory at Hogwarts.
Often, Luna Lovegood can be found in such fanfictions. Her unique and dreamy nature could bring a different dynamic to the harem. Neville Longbottom might also be involved in some way, perhaps as a friend who supports the harem and helps them out in times of need. There could also be some foreign exchange students or magical creatures in human form that end up in the harem for various reasons.
The original Harry Potter story has a well - established set of characters and their relationships. In this fanfiction, it throws that all into chaos. The dynamics between Harry, Fleur, and other characters like Hermione, Ron, and Bill are completely rewritten. This not only affects the individual characters but also the overall fabric of the wizarding world as presented in the fanfiction.
