There could be such a 'harry hates humans fanfiction'. However, it's not a very common or mainstream concept. It might be a more niche or dark take on the character. Maybe some independent authors have explored this idea, but it's difficult to point to one without really delving deep into the fanfiction communities and their libraries. It could also be that this is a very specific or even self - created concept that hasn't been widely explored in the general fanfiction world yet.
One possible plot could be that Harry has been repeatedly betrayed by those he trusted, all of whom are humans. This string of betrayals causes him to gradually develop a hatred for all humans. He might then go on a journey to isolate himself from human society and seek revenge on those who wronged him.
One possible reason could be the betrayal he faced from some people in the wizarding world. For example, some students at Hogwarts might have spread false rumors about him or treated him unfairly because of his fame as 'The Boy Who Lived'. This could have led him to develop a general dislike for humans.
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.
Well, it completely flips his character. Normally, Harry is seen as a hero who is kind - hearted and protective of his friends and the wizarding world. In this fanfiction, he becomes a much darker and more jaded character. His hatred for humans makes him more of an anti - hero or even a villain - like figure in some ways.
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.
The plot could start with Naruto isolating himself from the village. He might go on a journey alone, avoiding any contact with humans. Along the way, he could encounter some non - human creatures who show him kindness, which makes him question his hatred.
Fanfiction.net is a well - known platform where you might find 'ash hates humans' fanfictions. It has a large collection of fan - created works across various fandoms, including Pokémon. There's a good chance you'll come across stories with this theme there.
One possible reason could be betrayal. If Naruto was constantly let down or betrayed by those he trusted among humans, it could lead to his hatred. For example, if his friends turned on him because of his jinchuriki status.
A fanfiction could also revolve around an alternate universe where Ash is born into a world where humans are extremely cruel to Pokémon. Ash, having a deep connection with Pokémon, starts to hate humans for their mistreatment. He could then start a revolution of sorts, trying to protect Pokémon from humans, which would be a very interesting take on the 'ash hates humans' concept.
