What could be the plot of a 'Harry Potter, King of Hogwarts' fanfiction?

Well, it could be about Harry facing an even greater threat than Voldemort. Maybe a new dark wizard emerges from the shadows and Harry has to use all his skills and the support of his friends to defend Hogwarts as its champion. He might have to go through a series of super - difficult challenges that test his magic, courage and loyalty to an extreme level.

One possible plot could be that Harry Potter, as the new owner of Hogwarts, decides to reform the school's curriculum. He might introduce new magic subjects that were previously overlooked, like ancient rune magic for practical applications.

Perhaps Harry is teaching Potions in the fanfiction. Since he had a bit of a rocky start with Potions in his student days, he could be a very understanding teacher. He might encourage students to experiment more, which is different from Snape's strict methods. He could also share stories about how important Potions were in his adventures, like when they made Polyjuice Potion. This would make the class more interesting and inspire students to take Potions more seriously.

Well, it could be about Harry's journey to fully embrace his role as a prince in Hogwarts. Maybe he discovers some long - lost royal heritage of the wizarding world that gives him new powers and responsibilities.

Well, perhaps the plot could involve Harry using his newfound powers to bring about major reforms in Hogwarts. He might control the curriculum to include more practical magic for real - world situations.

One possible plot could be that Harry travels back in time to become the founder. He uses his knowledge of future dark wizards to set up defenses in Hogwarts. For example, he could create a special chamber to hide something crucial, just like the Chamber of Secrets, but with a different purpose.

In this fanfiction, perhaps Harry decides to renovate Hogwarts. He could add new sections for different types of magic study, like a special wing for time - traveling magic research. Also, as the owner, he'd have to deal with the political aspects of the wizarding world trying to influence the school's curriculum.

The pure - blood supremacist families could be the main antagonists. They might see Harry as a threat to their traditional ways of running Hogwarts. They would oppose his new rules and reforms that aim for a more inclusive and equal school. For example, they could try to undermine his authority by spreading false rumors about him among the students and their families.

It could be that there's a powerful enemy that has taken over Hogwarts and Harry, in a desperate attempt to stop this evil from spreading, resorts to destroying the school. He might think that rebuilding it later is better than allowing it to be used for evil purposes. For example, if Voldemort had found a way to permanently taint the magic of Hogwarts, Harry might see destruction as the only option.

One possible plot could be a ninja from a far - off land arriving at Hogwarts under mysterious circumstances. Maybe they are on a quest to learn a special type of magic that only Hogwarts can offer. They could end up befriending Harry Potter and teaching him some ninja skills in return for learning about wizardry.
