With the Hogwarts faculty, some teachers might be more lenient towards him. They might sense that he has had a difficult past with his health. For example, Professor McGonagall could show more motherly care. His relationship with Hagrid could also be different. Hagrid might be more protective of Harry, knowing that he has already faced a great struggle with cancer.
His relationship with the Dursleys might be more complex. They could be even more cruel, seeing him as a burden because of his cancer. Or, in a different take, they might feel a bit of pity and be slightly less horrible. As for his friends at Hogwarts, he might be more guarded at first. He has been through a tough time with his health, so it could take him longer to open up to Ron and Hermione.
Harry's relationship with his enemies would also be different. Voldemort might see him as a more formidable opponent due to his dual nature. He might try to turn Harry's demonic side against the wizarding world. On the other hand, Harry's angelic side could make some of the Death Eaters question their loyalty to Voldemort as they see a glimmer of hope in Harry. Overall, his relationships would be in a state of flux as he tries to navigate his new identity and the reactions of those around him.
Well, it would probably strengthen his relationship with his friends. His friends would be happy for him to have his parents back, and it could lead to more group activities like family - style outings. For instance, they might all go on picnics together with Harry's parents.
The wizarding world would be in chaos. Voldemort might not be as threatened as he was with Harry around. The prophecy about Harry being the one to defeat Voldemort would be nullified, and the dark forces could gain more power. Hogwarts itself might lose some of its hope and protection as Harry was seen as a symbol of the future in the fight against the dark arts.
The fandom would be divided. Some fans who are deeply into fanfiction would be disappointed and might feel like a part of their connection to the 'Harry Potter' world has been cut off. However, others who are more focused on the official works might not be as affected. There would likely be a decrease in the variety of fan - created stories, which could limit the creative exploration within the fandom.
One possible storyline could be that Harry's experience with cancer makes him more resilient. He might have faced his own mortality at a young age, so when he enters the wizarding world, he has a different perspective on danger. For example, he may not be as afraid of Voldemort as others because he has already fought a life - threatening battle with cancer.
In the fanfiction world, Harry might be the heir to Hogwarts if there was some sort of magical pact made generations ago. For example, perhaps one of his ancestors had a special role in the creation or protection of Hogwarts, and this role was passed down through the family. It could also be that his unique magical abilities, like his ability to resist Voldemort's attacks from a young age, are signs of a deeper connection to Hogwarts itself. This connection could be what designates him as the heir in the fanfiction's plot.
His friends might be a bit worried at first. Hermione, for sure, would be concerned about the potential danger of having a snake around. Ron might be a bit scared too, considering his fear of spiders and general uneasiness around things that seem a bit dark. But if the snake turns out to be helpful, they might come around.
His relationships would likely be very different. For one, he might be more of an outsider. The other students grew up in the wizarding world in a more common way, while Harry was raised by the Flamels. He could be seen as having an unfair advantage in terms of magic knowledge. But on the other hand, he might also be respected more for his unique upbringing.
It would completely change the nature of the story. Harry Potter is seen as a hero, and this act would make him a villain. It would be a huge deviation from the original story's positive values.
Yes, it can be. Many fanfiction writers like to explore unique perspectives, and having Hogwarts as an observer or an active part in Harry's life stories can be very appealing. It allows for a different take on the familiar storylines.
