In this fanfiction, it might be that there was a huge crisis at Hogwarts when Harry was 11. All the other potential candidates for headmaster were unavailable or incapacitated. Harry, with his already proven heroics, was seen as the only hope. The Ministry of Magic, in a desperate move, appoints him as headmaster. He then has to grow up really fast and learn how to manage the school while still being a child in many ways.
Maybe it's a magical twist. There could be a prophecy that states Harry must take on the role early to save Hogwarts from a great threat. So, the wizarding world bends the rules for him.
A popular choice could be a character like Sirius Black. If he had survived, he could have become headmaster with his rebellious yet caring nature. He would bring a different kind of leadership to Hogwarts, one that is more in tune with the students' desires for change and adventure.
In my opinion, Dumbledore would still be a great headmaster in fanfiction. His wisdom and experience are invaluable. He always had a deep understanding of the students and was able to guide them through difficult times. He also had a great sense of humor and was very approachable despite his great power.
In this fanfic, there could be a storyline where Harry discovers a hidden part of Hogwarts history as headmaster. This discovery could lead to new magical revelations and he has to decide how to share this knowledge with the students and the wizarding community. Also, he may have to deal with students who idolize him too much and the pressure that comes with being a role model in such a close - knit community.
In a 'Harry is headmaster' fanfiction, the story could start with Harry being offered the position due to his heroic deeds. He would then have to deal with the bureaucracy of running the school. He might face challenges from traditionalist teachers who oppose his new ideas. For example, he could want to introduce a new class on modern Muggle technology in magic. As he progresses, he would also have to handle student issues, like bullying among houses or problems with students' magical abilities not being properly nurtured.
In such a fanfic, Harry might bring a lot of changes to Hogwarts. He could introduce new courses that focus on real - world magic applications, like how to use magic for environmental protection. Also, he would probably be very strict about the safety of students, especially after all his own dangerous experiences at school.
Another challenge would be handling the different houses. Each house has its own identity and sometimes rivalries can get out of hand. A new headmaster would need to find ways to promote unity among the houses, like through new inter - house competitions or joint projects.
One plotline could be that this non - Hogwarts headmaster comes to Hogwarts on an exchange program. They bring their own unique magical curriculum and start to change the way students think about magic. There could be conflict with the traditional Hogwarts professors who are resistant to change.
He might add a course on the history of the Dark Arts, not just the dark spells but also the people and events that led to their creation. This would give students a deeper understanding of what they're up against. For example, they could study the rise of Voldemort in more detail, including the social and political climate that allowed him to gain power.
He might add more practical magic courses. For example, he could introduce a course on advanced Patronus charm techniques. This would be useful for students to protect themselves in the real world. He may also include a unit on magical creatures' rights and how to interact with them ethically, as he has his own experiences with various magical creatures.
The headmaster might have a huge impact on Harry's development in his fifth year. He could expose Harry to different magical cultures and theories that are not part of the regular Hogwarts curriculum. This would expand Harry's magical knowledge and way of thinking. Also, the headmaster could help Harry better control his emotions, which are often in turmoil during this year. By teaching him meditation or other mental control techniques, Harry would be better equipped to handle the stress and challenges.
