Well, it changes the perception a great deal. In the normal 'Harry Potter' world, we expect Harry to look up to McGonagall. But in this fanfiction, the hatred creates a new dynamic. It might make readers see McGonagall from a different angle too, as they wonder what she has done to make Harry feel this way. It could also lead to a re - evaluation of her character traits and actions within the context of this alternative story.
It completely flips their relationship. In the original story, McGonagall is a respected figure for Harry. But in this fanfiction, the hatred makes their interactions tense and negative.
The fanfiction makes their relationship more complex. Instead of the usual mentor - mentee bond, it becomes a relationship full of conflict. Harry's hatred might lead to different storylines, like him trying to avoid McGonagall or even oppose her in some matters.
This idea completely alters the perception of the Harry Potter universe. In the original, Harry is at the center of a community of friends and allies. If he hates humans, that community is shattered. It also changes the way we view the magic world's relationship with the non - magical world. Harry was always a bridge between the two, but if he hates humans, that bridge is broken. It creates a much more fractured and less hopeful view of the entire Potterverse.
McGonagall might notice Harry's distrust and feel hurt or frustrated. She may try to figure out what went wrong but find it difficult as Harry is not forthcoming. Their interactions become less warm and more formal. For example, in class, Harry may be less likely to ask for help from McGonagall, and McGonagall may be more strict with Harry as she doesn't understand his change in attitude.
It completely flips the usual narrative. In the original story, Harry has a sense of longing for his family, especially his parents. But in this fanfiction, the hatred changes the emotional core. It makes Harry a more complex and perhaps darker character. The relationships that were once sources of strength, like his connection to his parents through their sacrifices, now become sources of bitterness.
It completely flips the perception. Instead of the loving Edward, we see a hating one. It makes Bella seem less desirable perhaps. Fans who read this fanfiction might start to view Bella as someone who has done something wrong to make Edward hate her, changing her from the love - interest to a more complex, possibly unlikable character.
This type of fanfic might shift the focus from the fight against Voldemort to the internal conflict between Harry and Dumbledore. It could explore different character traits of both of them that were not as prominent in the original. For example, Harry's potential for anger and Dumbledore's more flawed side.
It makes their relationship seem less adversarial. It gives the idea that there's more to them than just being enemies.
She becomes more nurturing. Usually, she's known for her strictness at Hogwarts, but when she adopts Harry, she softens up. For instance, she might show more patience when Harry makes mistakes in his magic studies.
It makes their relationship seem more complex. Instead of just being friends or comrades, the roasting adds a layer of banter.
Well, it completely flips it. In the original, Naruto is all about being a ninja and achieving his dreams as a ninja. But in this fanfiction, he hates them. So it makes us see a more cynical side of Naruto that we don't usually associate with him.
Maybe in that fanfiction, McGonagall has some actions that Harry misinterprets. For example, she might be too strict with him in a way that he can't understand at that moment.
