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.
A really interesting plot twist could be that Dorea Black, due to her own experiences and beliefs, decides to raise Fem Harry as a sort of 'pure - blood rebel'. She teaches Fem Harry to question the traditional pure - blood values that many in the Black family hold dear. This causes a rift within the Black family as some support Dorea's new approach while others are appalled. As a result, Fem Harry grows up in the middle of this family drama, which shapes her into a unique witch who has to navigate not only the usual Hogwarts challenges but also the internal politics of the Black family.
One possible plot twist could be that Dorea Black, being a pure - blooded Black, tries to instill in Harry a strong sense of pure - blood pride in a different way than the Malfoys. Instead of the usual haughty and discriminatory way, she teaches him about the history and magic of their bloodline in a more positive light. This could lead to Harry having a different perspective on the wizarding world's social hierarchy.
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.
One interesting plot could be how Dorea Black's different values and family traditions shape Harry's upbringing. Maybe she instills in him a stronger sense of pure - blood pride in a more positive way compared to the negative connotations in the original series. Another plot might involve how Harry's relationships with other characters, like Ron and Hermione, develop differently under Dorea's influence.
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.
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.
One possible plot twist could be that Sirius Black, being a wanted man, has to constantly move with Harry to avoid capture. This would make Harry's childhood very different from the one at the Dursleys. He'd grow up learning about the wizarding world on the run, perhaps meeting some unique characters in hiding places.
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.
