One possible plot could be that Harry is on a secret mission in the Muggle world. He has to blend in, so he stays with a Muggle family. While sleeping there, he has strange dreams related to his wizarding past and future challenges. He also has to be careful not to accidentally use magic while asleep, which could expose him.
There might be some fanfics with this concept that are family - friendly. However, it depends on how the author has written it. Some may focus on a more innocent or platonic relationship that just involves Harry being around Muggles while sleeping, perhaps in a hiding - out - with - friendly - Muggles - during - danger kind of scenario.
Well, one possible reason could be their ignorance of the magical world. Muggles, not understanding magic, might accidentally trigger events that lead to destruction. For example, they could unknowingly interfere with magical spells or artifacts that are crucial for maintaining the balance of the world.
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.
In such fanfiction, Muggles can be shown in different lights. Some portray them as simple and uncomplicated, living their ordinary lives without any knowledge of magic. However, there are also fanfictions where Muggles are more curious or even a bit envious of the magical abilities of Wizards. They might be depicted as trying to find out about the wizarding world despite the secrecy.
One 'badass muggle' could be a character who manages to outwit dark wizards using just their street smarts. For example, in some fanfics, there are muggles who are really good at martial arts and they use their physical skills to hold their own against wizards who underestimate them.
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.
It might show a relationship full of misunderstandings. Muggles are unaware of the magical world, and the magical world has to keep its secrecy. So there's a lack of communication, which can lead to problems later.
One possible scenario in a Harry Potter fanfic could be an avalanche occurring near Hogwarts, and somehow Sleeping Beauty is brought into the wizarding world. Maybe a spell gone wrong transports her there during the avalanche. The students at Hogwarts might be curious about this strange new arrival and her story from the fairy - tale world.
No, they are not very popular. The original 'Harry Potter' series is loved for its themes of magic, good vs. evil, and coming - of - age. Fanfictions that involve 'Harry Potter and Muggles' in a lemon context often go against the general tone of the series. Also, the official 'Harry Potter' brand promotes a family - friendly environment, so such fanfictions with adult - like content don't really fit into the mainstream popularity of the 'Harry Potter' fandom. They are more of a niche and often not well - received by the general fan community.
