The overarching plot of the fight against Voldemort could be different too. In the original, Harry was driven by the desire to avenge his parents. In this fanfiction, if he has a different view of Dumbledore and his parents, his motivation might shift. He might be more focused on getting answers about why Dumbledore did what he did rather than just fighting Voldemort. This could lead to a whole new set of adventures and challenges in the story.
It might also affect the relationships Harry has with other characters. In the original, his friends sort of filled the void of his missing parents. But in this fanfiction, if he discovers that Dumbledore kept him from his parents, he might be more withdrawn and less trusting, which would change the dynamics with his friends like Ron and Hermione. And it could also change his relationship with the Hogwarts faculty as a whole.
Well, it changes the emotional core of the story. In the original, Harry's longing for his parents was a huge part of his character. But in this fanfiction, that longing might be more complex. For instance, if Dumbledore's actions were unjust, Harry could have a sense of betrayal towards Dumbledore, which is different from the original where Dumbledore was mostly seen as a mentor.
Well, it completely flips the traditional view of Harry's relationship with his parents. Instead of the usual love and respect, there is now this conflict. It makes the story darker and more complex as Harry is no longer the hero with the perfect family background.
Well, it completely flips the typical relationship dynamic. Usually, Harry idolizes his parents. But in this fanfiction, by disowning them, it creates a sense of conflict and chaos. It might make the story darker as Harry is now sort of an outcast not just in the wizarding world in general but also from his own family legacy.
Well, it would change the power dynamic. Usually, Dumbledore is seen as a guiding figure for Harry. If Harry stops listening, he might make more mistakes as he lacks Dumbledore's wisdom. For example, in battles, he might not make the strategic decisions that Dumbledore would have advised.
Well, it completely flips the story on its head. Dumbledore is a central and positive figure in the original. His death is a major turning point, but for Draco to kill him for Hermione means Draco's character has a huge shift. It also makes Hermione a much more central and controversial figure, as her presence has now caused such a drastic event. The relationships between the main characters like Harry, Ron and Hermione would be severely strained as they deal with this new and unexpected development.
Perhaps Dumbledore foresaw some sort of prophecy that was related to Harry and his parents. In order to fulfill the prophecy in the right way or to avoid a greater catastrophe, he kept Harry from his parents. He was always thinking about the greater good of the wizarding world and might have believed this was a necessary step.
Yes, there are likely fanfictions out there with this dark and alternative take. Fanfiction often explores non - canonical ideas, and this would be a very radical one. It goes against the established lore in the official 'Harry Potter' series, but that's the nature of fanfiction - to play with different concepts.
The 'Snape kills Harry' fanfiction would shatter the relationships that were built in the original series. For example, the friendship between Harry, Ron, and Hermione would be left in tatters. Hermione and Ron would be devastated and likely seek revenge. Also, Dumbledore's plan, whatever it was that involved Harry, would be completely ruined. The whole balance of good and evil in the wizarding world would be thrown into chaos.
This type of fanfiction can also change the character interactions. Friends of Harry and Ginny may be forced to take sides or try to reconcile them. For instance, Hermione might be in the middle, trying to figure out what went wrong and how to fix it. It can make the story more about relationship drama rather than the typical Harry Potter adventures against dark forces.
It shakes the foundation of the trust that fans have in the characters. Dumbledore is often seen as a wise and benevolent figure. If Harry destroys his reputation, it makes fans question all the previous events and decisions that Dumbledore was involved in. For example, his guidance to Harry might now seem suspect.
The relationships in the story are affected too. Harry's relationship with Dumbledore would become strained. Other characters who are loyal to Dumbledore might also turn against Harry. And Harry might form new alliances with characters who also have doubts about Dumbledore's leadership in this fanfiction.
