There could be a fanfic where a group of rogue Death Eaters, who were never caught after Voldemort's fall, start a new wave of Muggle murders. They might be using new and more sinister magic to carry out their evil deeds. In the fanfic, Hermione could use her intelligence to research old and forgotten spells to counter their attacks.
I'm not sure if there are extremely well - known ones specifically about this topic. Fanfic communities are vast, and while there might be some that touch on this dark theme, they may not be mainstream. It could be that such fanfics are more likely to be found in the darker corners of the 'Harry Potter' fanfic world.
Some muggles in fanfiction could be the relatives of a half - blood wizard. These muggles might have a hard time understanding their wizarding family member's abilities at first. They could be initially skeptical or even scared when they witness magic. However, as the story progresses, they might come to accept and even be in awe of the wizarding world.
Well, I'm not sure of a specific 'Harry Potter and Muggles' lemon fanfiction off the top of my head. But generally, in such fanfictions, they might explore how Muggles would react to the magical world in a more intimate or romantic context. But again, due to the nature of lemon content, it's not always easy to recommend as it goes against the family - friendly nature of the original 'Harry Potter' series.
Some fanfictions might have a plot where the muggle family tries to 'cure' Harry of his magic. They could take him to various doctors or therapists thinking he has some sort of mental disorder. Meanwhile, Harry is feeling more and more isolated and confused. When he does meet someone from the wizarding world, like a Hogwarts teacher who comes to check on him, it's a moment of great relief and the start of a new journey.
Perhaps a story where Harry helps a muggle child who is being bullied. He uses his magic to give the child the confidence to stand up for himself. He might also use some minor spells to make the bully realize the error of their ways, but in a way that doesn't expose the wizarding world to the muggles.
One interesting concept could be how muggles react to the magical world. For example, they might be in awe of the simplest spells like Lumos. Another could be the friendships that form between muggles and wizards in the fanfiction. It can show a unique dynamic as they learn from each other.
Their underdog status. Muggles in the Harry Potter world are seen as inferior in terms of power compared to wizards. So when a muggle is 'badass', it's like a David vs Goliath situation. They have to rely on their non - magical skills and wits to overcome magical challenges, which is really exciting to read.
One interesting fanfic could be one where Flamel mentors Harry in the secrets of alchemy. Maybe in this fanfic, Flamel reveals ancient spells related to transmutation that were not known in the original books.
One interesting 'Harry Potter' fanfic could be those that explore different relationships between the characters. For example, a fanfic might focus on the friendship between Harry and Neville in more depth, showing how they support each other in ways not fully explored in the original books. Another could be a time - travel fanfic where a character goes back in time to change certain events in the wizarding world. There are also fanfics that might give more backstory to minor characters like Luna Lovegood, making her character even more fascinating.
One interesting fanfic could be about James Potter's time at Hogwarts before he met Lily. It might explore his friendships, his pranks, and how he grew as a wizard. For example, it could show his rivalry with Snape in more detail, giving insights into their complex relationship.
