Fanfiction about Harry Potter raised by Delacour: What could be the interesting plot twists?

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.

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.

Perhaps a plot twist could be that the magical creatures interact with Harry differently. In the original, they had a certain way of relating to him, but in this fanfiction, being raised as a black wizard might make some creatures more or less friendly towards him. Some might see him as a symbol of change in the wizarding world and be more drawn to him, while others might be suspicious. Also, the way Harry approaches magic could be different. He might draw on cultural magic that is unique to his black heritage, which could give him an edge in certain situations or make him a target for those who fear change.

A plot twist could be that Harry discovers a hidden prophecy related to his marriage with Fleur. This prophecy might involve a great danger that they have to face together, like an ancient dark magic that only their combined powers can defeat. It would add a layer of mystery and adventure to the fanfiction.

One possible plot twist could be that Kenpachi's rough and battle - hungry nature makes Harry a much more aggressive wizard. Instead of waiting for Voldemort to come to him, Harry might actively seek out dark wizards to fight. Another twist could be in the way magic is taught. Kenpachi, not being from the wizarding world, might introduce Harry to a more physical and unorthodox way of using magic, like using brute force in spellcasting rather than the traditional finesse. Maybe Harry would also develop a more carefree attitude towards the rules of the wizarding world, much like Kenpachi does with the Soul Society's rules.

Well, a really interesting plot twist could be his relationship with the other Hogwarts houses. He might not have the same automatic connection with Gryffindor. Instead, he could be more inclined towards Slytherin values, which would completely change his dynamic with Ron and Hermione. Maybe he would form closer friendships with Slytherin students right from the start. Also, his views on pure - blood supremacy could be more complex as he is raised in a family that might have some traditional views on blood purity.

Well, perhaps the nuns are in cahoots with some magical creatures. They could be working with a group of centaurs who have prophesied that Harry must be raised in seclusion among the nuns to gain a certain kind of purity of spirit. Then, when Harry finally enters the wizarding world, he has an aura about him that both attracts and confounds the dark forces. He might also have a special connection to the magical animals due to his time with the nuns, like being able to communicate with them on a deeper level, which would be really useful in his battles against the dark side.

A really interesting plot twist could be that the phoenix, being a symbol of rebirth, has the ability to make Harry remember his past lives. This would give him an edge as he could draw on the knowledge and skills from his previous existences. He might remember spells and strategies that were long forgotten, which would completely change the course of his fight against the dark forces.

One possible plot twist could be that Harry has unique magical abilities related to the ocean. For example, he might be able to communicate with sea creatures, which could help him in his adventures. Maybe he discovers a hidden underwater wizarding community that has been isolated from the rest of the wizarding world for centuries. Another twist could be that his enemies, like Voldemort, have a hard time reaching him in the ocean, but they find a way to use the ocean's power against him in some unexpected manner.

One possible plot twist could be that Dorea Black, being from a pure - blood family, tries to shield Fem Harry from the growing dark forces in a different way than the Dursleys did in the original story. Maybe she uses her family's old magic and connections to give Fem Harry a more magical - centered upbringing, which leads to Fem Harry having a different set of skills and knowledge earlier on.
