In this 'Harry Potter adopted by French family fanfic', his family could introduce him to a whole new set of wizarding traditions. For example, French wizarding families might have different ways of celebrating holidays or coming - of - age ceremonies. Harry could also make new friends in the French wizarding community who have different personalities and magical abilities compared to his Hogwarts friends. His French family might also have a different attitude towards things like pure - blood and Muggle - born wizards, which could shape Harry's views in a new way.
The Grangers. Hermione's parents are Muggles, but if they were made aware of the wizarding world early on, they could adopt Harry. He'd have a stable, loving home environment and would also be exposed to Muggle knowledge, which could be really useful in his magical studies. For example, scientific methods could be applied to understanding some aspects of magic better.
Well, he might grow up with a different set of values and magical education. The Greengrass family is known for their pure - blood status. Harry could have a more refined upbringing in terms of pure - blood traditions. He might also have a different relationship with the wizarding world at large, perhaps being more involved with the pure - blood society.
Well, if Harry Potter was adopted into the Malfoy family in fanfic, his life would change drastically. He would be exposed to a world of luxury and privilege that he has never known before. However, he would also be under the watchful eyes of Lucius and Narcissa Malfoy. They might try to mold him into their idea of a proper pure - blood wizard. But Harry, being Harry, would likely resist some of their attempts. And his presence in the Malfoy family could also potentially cause a rift between the family and Voldemort, since Harry is Voldemort's nemesis.
The Malfoy family would have to reevaluate their pure - blood ideology. Having Harry, who is a symbol of the defeat of pure - blood supremacist Voldemort, in their family would be a big shift. They might become more open - minded towards non - pure - blood wizards. Also, their relationship with the other Death Eaters would be strained as Harry is their enemy.
Well, perhaps Harry is adopted by a family of magical creatures, like centaurs. They teach him their unique ways of magic and understanding of the magical world. He could have a whole different perspective on things like divination, as centaurs are known for their prophetic abilities. It would be really interesting to see how he interacts with his human friends at Hogwarts after growing up in such a different environment.
There are likely some out there. Fanfic writers often come up with all sorts of imaginative ideas. A French bunny in a Harry Potter fanfic could be used to add a touch of whimsy to the story. It might have a distinct French accent when it communicates (in the magical way that animals do in the Potter world) and be involved in adventures across the wizarding world, from the streets of Diagon Alley to the grounds of Beauxbatons Academy.
One interesting 'Harry Potter family' French fanfic could be one that focuses on the Weasley family's daily life in a more detailed way, perhaps exploring how they manage with all their children during the holidays. Another could be about the Potter family's legacy and how it affects future generations in the wizarding world. There are also fanfics that might explore the relationship between Harry and his parents in a magical realm where they can interact more, like in a dream - like scenario.
His story would change a great deal. For starters, he might not have the same connection to the Dursleys. His early years would be filled with the Greengrass family's values and lifestyle. He could be more attuned to pure - blood politics from a young age.
