The plot could take a turn where Harry's role in the fight against Voldemort is completely different. Instead of being the 'Chosen One' in the traditional sense, he might be more of a behind - the - scenes player. His upbringing by the Greengrass family could give him access to different resources and knowledge. He could use his position in the Slytherin - influenced environment to undermine Voldemort's forces from within. For example, he might be better at infiltrating the Death Eaters' ranks due to his family connections and the skills he learned growing up in a more Slytherin - like household.
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.
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.
Well, perhaps the Black family's dark magic artifacts play a huge role. Harry could be exposed to them at a young age. He might start to show an aptitude for certain types of dark magic not seen in the regular series. But then he has to struggle with whether to embrace this power or reject it, knowing it goes against what Dumbledore and others would expect.
A plot twist could be that Madame Maxime, being half - giant, imparts some of her physical and mental toughness on Harry. This makes him a more formidable opponent in duels and other challenges. In the story, this might lead to him being targeted earlier by Voldemort's forces because they see him as a greater threat. Also, the Beauxbatons Academy environment, which he would be more familiar with due to being raised by Madame Maxime, could have different magical traditions. These traditions could either help or hinder Harry when it comes to facing the Dark Lord. For instance, they might have different ways of casting defensive spells that Harry has to adapt to the British magical world.
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.
One possible plot twist could be that Harry Dresden's magic system clashes with the wizarding world of Harry Potter. For example, Dresden's more rough - and - tumble approach to magic might get him in trouble with the Ministry of Magic. Another could be that Harry Potter, being raised by Dresden, develops a very different personality. He might be more street - smart and less naive compared to his original self. Also, there could be a plot twist where the enemies from Dresden's world start targeting Harry Potter because of his connection to Dresden.
A plot twist could be related to Fem Harry Potter's magical abilities. Since she is raised by Crowley, she might develop some unique magical skills that are a blend of wizarding magic and Crowley's own brand of 'power'. This could make her a target for various groups in the wizarding world who either want to use her for their own gains or are afraid of her new - found powers. Also, Crowley might have some enemies in the wizarding world that he has never revealed to Fem Harry Potter. When these enemies discover her existence, they target her to get back at Crowley, putting her in great danger and forcing her to rely on skills and knowledge she has learned from Crowley to survive.
One possible plot twist could be that Rowena Ravenclaw imparts her extreme intelligence to Harry in a very different way than Dumbledore or the other Hogwarts founders might have. Maybe she teaches him some long - lost magic that gives him an edge over Voldemort early on. Another could be that Harry's connection to Ravenclaw makes the other houses view him with suspicion, leading to a more complex social dynamic at Hogwarts.
