One possibility is that Harry grows up in a more refined and magical environment. The Delacour family might introduce him to different aspects of French magic. He could be trained in unique spells and magical traditions. Also, he might have a different relationship with the magical community, perhaps being more involved with international magical relations from an early age.
Maybe Harry would have a different view on the wizarding world. Growing up with the Delacours, he'd be exposed to a more international magical community from a young age. So, instead of being so focused on the British wizarding world's problems like Voldemort, he might be more interested in international magical relations and how to unite different magical cultures.
He'd probably be more sophisticated. The Delacour family is known for their elegance and grace. Harry might have a more refined way of speaking and acting compared to his canon self. For instance, he would be more likely to use formal French wizarding greetings.
He might be more refined. The Delacour family seems to have a certain elegance about them. Harry could be more sophisticated in his speech and mannerisms. He may also be more confident in social situations as he would have grown up in a family used to high - society magical events.
There could be various fanfictions involving Gabrielle Delacour and the concept of a lemon (which might symbolize something refreshing or unique in the story). One possibility is that it could be about Gabrielle's adventures in the wizarding world where she discovers a magical lemon with special properties. Maybe it gives her the ability to communicate with magical creatures that are attracted to its scent.
In the original series, Harry's character is shaped by his difficult life with the Dursleys. But in this fanfic, with the Delacours, he might be more refined and have a different sense of propriety. For example, he could be more accustomed to the high - society aspects of the wizarding world.
Perhaps a major plot twist is that Harry's connection to Voldemort is affected. In the original story, his connection was partly due to his being a Horcrux. But growing up with the Delacours, he could have been protected in a different way that changes this connection. He might not have the same nightmares or visions as he did in the books. Also, his role in the Triwizard Tournament could be completely different. Instead of being the unexpected fourth champion from Hogwarts, he could be an observer or a special guest from Beauxbatons, which would change the whole dynamic of that event.
Obviously, the Delacour family members are main characters. Fleur Delacour, who we already know from the original series, is likely to play a significant role. Her parents, Monsieur and Madame Delacour, might also be important as they could be the source of family magic and traditions.
One common theme is the exploration of the wizarding world's culture. Since Apolline is from the French wizarding community, many fanfictions use her character to showcase different cultural aspects, like unique spells or traditions. For example, in some stories, she might introduce Harry to a French - based magical art form.
Well, one possible plot could be that after Harry's difficult life at the Dursleys, Fleur Delacour discovers his situation. She decides to adopt him out of pity and a sense of justice. Harry then gets to experience the wizarding world from the perspective of the Delacour family. He might learn different magic techniques that are more common in the French wizarding community. He could also form new friendships with Fleur's younger sister or other relatives. And perhaps he'll have a different role in the fight against Voldemort, with the support and resources of the Delacour family.
