The plot could take a turn where Pan Son is initially thought to be a normal Muggle, but as he grows up with Harry, it's revealed that he has a dormant wizarding bloodline. This discovery could come at a crucial time, like when Harry is facing a great threat. Pan Son's newfound magic could be the key to turning the tide. They would then have to train Pan Son quickly and figure out how to integrate his magic into their fight against the dark side.
One possible plot twist could be that Harry, under Crowley's influence, starts to question the traditional concepts of good and evil in the wizarding world. He might be exposed to dark magic in a different light, not as something purely evil but as a tool with its own uses. This could lead to conflicts with his friends from Hogwarts who adhere to the more conventional views.
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.
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 the founders' different teaching styles clash when raising Harry. For example, Salazar Slytherin might be more strict about pure - blood heritage, while Helga Hufflepuff would focus on his kindness. This could lead to internal conflicts within Harry as he tries to balance their different expectations.
One possible main plot twist could be that Sirius manages to completely hide Harry from the wizarding world's prying eyes until he comes of age. This would mean Harry grows up without the constant threat of Voldemort's followers finding him. Another twist could be that Sirius discovers some long - hidden magic within Harry that was dormant because of his upbringing with the Dursleys, but flourishes under Sirius's care.
One possible plot twist could be that Amelia Bones, being a highly respected figure in the wizarding world, has a secret past that somehow affects Harry's journey. Maybe she was involved in some sort of pre - Voldemort plot that resurfaces when she takes in Harry. This could lead to Harry having to deal with new enemies and allies that are related to Amelia's past.
Their friendship might develop through shared experiences. For instance, they could both face bullying at school. Harry is already known for being bullied by Dudley and his gang, and Pan Son might also face some form of exclusion. This would make them bond over their mutual hardships and they would become each other's support system. They would learn to trust each other and rely on one another's strengths.
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.
