Some good topics would be the exploration of different wizarding cultures around the world. How do the wizards in France or Bulgaria differ from those in Britain? Also, stories about the Hogwarts teachers' early years as students or their own adventures outside of Hogwarts. These topics stay true to the spirit of the Harry Potter universe and are suitable for fanfiction.
Another great topic is the relationships between characters in a non - romantic or non - sexual way. Such as the friendship between Hermione and Luna. How did they support each other during difficult times at Hogwarts? This kind of fanfiction can enhance the sense of community and friendship in the Harry Potter world.
Well, you could focus on the adventures of the characters outside of Hogwarts. Maybe write about Harry, Ron, and Hermione's travels during the summer holidays and the magical encounters they have in the Muggle world. Or you could center on the history of Hogwarts itself, like the founding of the houses and the secrets within the castle walls.
Another great topic is to expand on the backstories of minor characters. Like Neville Longbottom's family history and how it influenced his character growth. It can add more depth to the overall story and give fans a new perspective on the series.
One appropriate topic could be 'Harry and Hermione's study sessions in the library'. This would focus on their intellectual growth and friendship as they explore the magical knowledge in Hogwarts' library. Another could be 'Harry and Hermione's adventures in the Forbidden Forest', which would be in line with the adventurous spirit of the original series.
One great topic could be their adventures after Hogwarts. Maybe they go on a quest to find a lost magical artifact together. It could show how their skills as wizards complement each other.
One great appropriate Harry Potter fanfiction is 'The Life and Times of Scorpius Malfoy'. It offers a fresh perspective on the post - Potter wizarding world through the eyes of Scorpius. Another is 'A Very Potter Musical' - inspired fanfictions that focus on the humor and camaraderie among the characters. Also, there are many that explore the backstories of minor characters like Neville Longbottom in a positive and family - friendly way.
One popular type of appropriate Harry Potter fanfic is the 'what - if' scenarios. For instance, what if Harry had been sorted into Slytherin? Writers explore how his character would develop differently, his relationships with other students, and how it would change the overall story. There are also fanfics that are set in the future of the wizarding world, showing the next generation of witches and wizards at Hogwarts.
One interesting topic could be exploring the backstories of minor characters. For example, what was the life of Neville Longbottom's parents like before they were tortured? Another could be alternate endings, like if Voldemort had won. And also, the relationships between different houses that we don't see much in the original books, such as how Gryffindors and Slytherins could have interacted more positively.
Another good topic could be Harry's role in rebuilding the wizarding community. How he uses his influence and experience to make the world a better place for wizards and witches alike. This can involve things like improving Hogwarts, or establishing new magical institutions.
One appropriate theme is to rewrite certain parts of the story from a different character's perspective. For instance, seeing the events of the Triwizard Tournament from Cedric Diggory's point of view. Or exploring how the wizarding world copes with the aftermath of the Battle of Hogwarts in different regions that were not covered in the original books.
