One possible reason could be a personality clash. Harry might have a very different personality from his mother. He could be more adventurous and she might be overprotective, which could lead to resentment on his part. Fanfiction often takes the characters and twists their relationships in unexpected ways.
One possible reason could be a divergence in the characters' personalities as portrayed in the fanfiction. Maybe the writer made Molly have traits that Harry would realistically dislike. For example, if Molly was written as overly controlling or mean-spirited towards Harry in the fanfic.
One possible reason could be that his family in the fanfiction might be cruel or neglectful towards him. Maybe they constantly put him down or don't support his dreams and ambitions, which would lead to his hatred.
Perhaps in this fanfiction, the author has imagined a completely different backstory for Harry. Maybe he was somehow mistreated by humans in this alternate story from a very young age. This continuous abuse or neglect could lead to him hating humans. But in the official Potterverse, Harry is a symbol of love and hope and friendship among humans, so this is a huge deviation. It could also be that the writer is exploring some complex psychological concepts by making Harry hate humans, like the effect of long - term isolation or extreme trauma on a person's view of humanity.
One possible reason could be misinformation. Maybe in the fanfiction, Naruto was told false stories about his mother that made him dislike her. For example, if he was told she abandoned him for some untrue reason.
One reason could be a divergence from the original friendship dynamic in the books. In the canon, Harry and Ron are good friends, and fanfiction that shows Harry hating Ron might go against what many fans consider the essence of their relationship.
Well, it could be that the fanfiction is trying to show Ginny's jealousy or resentment in a new light. Perhaps she's jealous of Harry's fame or the attention he gets. Or maybe the writer is simply exploring a 'what if' scenario where Ginny and Harry's relationship took a different turn from the start. In the original story, they end up together, but fanfiction allows for alternative storylines, and this could be one of them where Ginny hates Harry for various reasons that might be related to their different personalities, goals or the pressure of the wizarding world around them.
One possible reason could be that the fanfiction misrepresents the Uzumaki clan or Naruto's connection to it. Naruto has a deep and complex relationship with his Uzumaki heritage, and if the fanfiction distorts it, he might dislike it.
One possible reason could be that the fanfiction misrepresents Sakura's character. Maybe it portrays her in a way that she would never act in the original context of the series, which makes her seem out of character and thus causes dislike. Another reason might be that the fanfiction focuses too much on other members of Team 7 and sidelines Sakura, making her seem less important or relevant than she actually is in the story.
Well, one reason could be that fanfiction often takes creative liberties that might distort the original relationship between Poseidon and Percy in the official story. It could be that Poseidon is a very complex character in the original, and fanfiction simplifies or misrepresents him in a way that makes it seem like he 'hates' Percy in those fictional interpretations.
It could also be due to the overall tone and plot of the fanfiction. If the fanfiction has a dark or negative theme and Yasaka is a part of that in a way that makes Naruto seem to 'hate' her, it might be because the writer wants to create some sort of conflict. However, this may not align with the original essence of Naruto's character, who usually tries to understand and befriend rather than hate without a good reason.
