There may be some fanfics out there with this premise, but it goes against the general relationship dynamics in the official 'Harry Potter' universe. Usually, Harry respects and values Hermione. If such a fanfic exists, it might be written by someone who wants to explore a really dark or different side of the story, like if there was a major event that made Harry turn against Hermione in that fictional narrative. But I haven't actually come across one myself.
One possible reason could be a miscommunication. Maybe Hermione accidentally reveals a secret of Harry's that he didn't want known, and this causes him to feel betrayed and start to hate her. Another reason could be jealousy. If Hermione gets more attention or praise for her magical abilities than Harry in the fanfic, he might develop feelings of envy and hatred. Or perhaps there's a love triangle situation where Hermione is involved with someone Harry doesn't like, and that causes his hatred.
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.
One possible reason could be a misinterpretation of his character. In the original series, Harry Potter doesn't hate Muggles at all. But in this fanfic, perhaps the author wants to explore a 'what if' scenario where something drastic has happened to make him have such feelings. Maybe he's been betrayed by a Muggle - in the fanfic world, this could be a made - up situation that sours his view on all Muggles.
One possible event could be that Lupin lied to Harry about something important. In the world of Harry Potter, trust is a huge factor. If Lupin deceived Harry, it could easily turn Harry against him. Say, Lupin lied about his whereabouts during a crucial time when something bad happened, and Harry suspected Lupin's involvement.
The original Harry Potter story has a strong family - love - centered theme. Harry's parents' love for him was so strong that it protected him even after their death. In the 'Harry Potter hates his parents' fanfic, this central theme is completely changed. It's a deviation that changes the whole dynamic of the relationships in the story. It's like changing the core of a flower, everything else about the story will be affected, such as Harry's relationship with his friends who also respected his parents.
It's difficult to say if there are popular 'no magic harry potter fanfic'. The Harry Potter fandom is vast and diverse, and while most fans are drawn to the magic, there may be some who have created or are interested in non - magic fanfics. However, these might not be mainstream popular. Some might exist in smaller communities or on less - known fanfic platforms. They could be created by fans who are looking for a new perspective on the series, perhaps exploring how the characters would be in a more 'normal' world without magic, but they likely haven't reached the same level of popularity as the more traditional fanfics.
A squib in the Harry Potter universe is a person born into a magical family but lacks the ability to perform magic. In a 'no magic' fanfic, it could be really interesting to explore how a squib might navigate the wizarding world. They might face discrimination or be overlooked. They could also find unique ways to contribute, like being really good at understanding magical artifacts even without being able to use them.
Yes, there are likely some fanfics out there that blend the two. Some fans might be intrigued by the idea of Harry Potter characters exploring the lost city of Atlantis, with its own unique magic and secrets. It could involve Harry and his friends on a quest in Atlantis, facing new challenges and perhaps even learning new types of magic.
The original story builds on family love and loyalty. Lily's sacrifice is a cornerstone of the story. However, in the 'harry hates lily' fanfic, this concept is thrown out the window. It changes the way we view the Potter family relationships and the overall moral fabric of the wizarding world as presented in the original books.
