There might be a fanfiction where Voldemort returns in a more terrifying form. He has new, even more cruel and dark magic powers. He starts to corrupt the magical creatures around Hogwarts, like making the Thestrals go on a rampage, which is quite a scary concept.
One example could be a fanfiction where the Dark Mark starts appearing all over Hogwarts, and students start disappearing one by one, creating a very spooky atmosphere. The corridors are filled with an eerie silence and the remaining students are constantly in fear of being the next victim.
A Harry Potter scary fanfiction could involve the Forbidden Forest becoming a place of true horror. The centaurs are no longer friendly, and strange, shadowy creatures lurk in the darkest parts of the forest. Harry and his friends get lost in there and have to face these unknown terrors while trying to find their way out.
There could be fanfictions that center around Voldemort's rise to power in a much more gory and detailed way. For instance, they might describe his murders in a very vivid and disturbing manner, which is different from the relatively less graphic descriptions in the original books. This can make the fanfiction quite scary.
Well, in some nightmare fanfictions, Harry Potter might find out that his parents were actually evil all along. This completely changes his view of himself and his place in the wizarding world. Another example could be a fanfic where the magical world is slowly being destroyed by a mysterious force and the characters are powerless to stop it. It creates a very dark and hopeless atmosphere for the story.
One example could be a fanfiction where a character acts completely out of character in a cruel way towards others, like Harry Potter suddenly turning on his friends without any real motivation. Another might be a story that twists the original themes of love and friendship in the series into something cold and unfeeling.
One example could be a fanfiction where Harry Potter visits an Indian wizarding school that has its own unique houses based on Indian values like Dharma, Karma, etc. Another could be a story where Hermione has an Indian heritage and uses Indian magic spells along with the regular ones from the original series.
Fanfiction involving drugs is not in line with the positive values of the original 'Harry Potter' series, and I don't recommend seeking or promoting such content. J.K. Rowling created a magical world full of positive values like friendship, courage and justice, and we should focus on fan works that adhere to these values.
One example could be fanfiction that twists the characters' personalities in really dark and disturbing ways. For instance, making a usually kind character extremely cruel for no good reason. Another might be fanfiction that involves really gory and violent scenes that don't fit with the overall tone of the original Harry Potter series. Also, some fanfiction that delves into abnormal and uncomfortable relationships between the characters can be considered creepy.
There are fanfictions that center around the excitement of Hogwarts students during Quidditch matches. Harry, being a key player, is often depicted as extremely excited in these stories. His excitement might be about leading his team to victory, catching the Golden Snitch, or just the overall atmosphere of the intense sport. These fanfictions can really bring out the energy and enthusiasm of the characters.
Some fanfiction might involve a character like Hermione cheating on Ron in their relationship. For example, in certain stories, she might be magically influenced to develop feelings for another character and act upon them, which is considered 'cheating' in the context of the relationship established in the original series. However, this is a deviation from the original moral framework of the books.
One example could be fanfiction that reimagines the wizarding world's government structure. For instance, it might explore how different political ideologies like pure - blood supremacy as a form of extreme conservatism could be challenged in a more democratic wizarding society. Another could be about the power dynamics between different magical races and how they form political alliances or rivalries, much like real - world international relations.
One example could be a fanfiction where Harry feels bitter about the way the wizarding world treated him after the war. Maybe he realizes that he was used as a tool and feels resentment towards Dumbledore's manipulations. In this kind of fanfic, Harry might distance himself from his friends and struggle with his identity and purpose.
