Well, a really interesting plot twist could be that the prophecy about Harry and Voldemort takes on a different meaning when Harry is raised by Lily. Maybe the protection that Lily's love gives Harry is not just a shield against Voldemort's Killing Curse, but it also gives Harry some sort of special power or connection to the Dark Arts that he has to struggle with. And this could make the story a complex exploration of the nature of good and evil, as Harry is constantly tempted by this new aspect of his power while also trying to fulfill his destiny as the Boy Who Lived.
One possible main plot twist could be that Lily's magic, being different from the Dursleys', has a profound impact on Harry's early development. Maybe he starts showing advanced magical abilities much earlier because of Lily's nurturing and magical heritage. Another could be that the wizarding world has a different view of Harry since he was raised by a powerful witch like Lily, and they either fear or overly idolize him from the start.
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 main plot twist could be that Charlie's dragon - taming skills influence Harry in unexpected ways. For example, Harry might develop an affinity for magical creatures earlier than in the original story and use this knowledge to his advantage during his Hogwarts years. Maybe he'd befriend a dragon that later helps him in a dangerous situation.
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 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.
Perhaps a major plot twist could be that the values instilled in Harry by the Nathrezeim are not as dark as everyone expects. He might bring a new perspective to the wizarding world, one that challenges the traditional view of good and evil. For example, he could show that there are shades of grey in magic and relationships, and that not all associated with the Nathrezeim are purely evil.
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.
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.
