The headmaster might also be concerned about the freedom of expression of the wizarding community. Fanfiction is a way for many witches and wizards to express their love for the 'Harry Potter' story. However, given Harry's importance and his own personal experiences, the headmaster would have to balance between respecting Harry's request and not stifling the creativity of the community. He might explore options like having some sort of regulation or guidance for fanfiction rather than an outright ban as Harry seems to suggest.
The headmaster might be a bit surprised at first. He would likely respect Harry's opinion, though. He has always valued Harry's thoughts and feelings. He may start to think about the implications of fanfiction on the wizarding community and how it might affect the students and the overall perception of Hogwarts.
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.
One reason could be that Harry wants to preserve the integrity of his real story. Fanfiction often takes the original story in different and sometimes wild directions. He might worry that it could distort the truth about his adventures, his friends, and the sacrifices made. For example, some fanfictions might create romantic relationships that didn't exist or change the motives of characters, which could mislead those who are new to the real story of Hogwarts and his battles against Voldemort.
He could be shocked. Maybe there are some fanfictions that take a very dark turn or have unexpected pairings that he never thought of. He'd probably need some time to process such strange ideas. And he might also be curious to see how far the creativity of the fans can go. He might even get some new ideas about his own life from reading some of the more imaginative fanfictions.
Snape would likely be initially suspicious. He's not used to Harry coming to him for help or sharing secrets. But once he realizes the seriousness of what Harry is saying, he might start to see Harry in a new light. He could be grudgingly helpful, still maintaining his cold exterior but secretly starting to feel a bit more protective of Harry.
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.
Hermione, on the other hand, would likely have a more critical view. She'd analyze the fanfictions for their accuracy in terms of magic lore and Hogwarts traditions. If there were any inaccuracies, she'd be quite perturbed. However, she might also appreciate the creativity that goes into some of the well - written ones that add new dimensions to their magical world.
He might be amused. Harry has a sense of humor, and the often absurd and comical situations in Blackadder fanfiction could make him laugh.
There's a chance he'd be inspired. The stories of the Naruto characters' determination and growth in the fanfiction could stir something in him. He might think about his own journey as a wizard and how he can further develop his skills and character, taking cues from the Naruto characters' tenacity.
At the beginning, Harry would be frightened. He's in an unknown place with Loki, who is known for his trickery. But Harry is no pushover. He would quickly gather his courage. He would remember all the times he's faced danger at Hogwarts. He might try to communicate with Loki to understand his motives. If Loki reveals that he wants to use Harry's magic for something, Harry would try to find a way to outsmart Loki. He could pretend to cooperate while actually looking for a weakness in Loki's plan. Harry would also be thinking about his friends at Hogwarts and how he needs to get back to them, which would give him extra motivation to fight back against Loki.
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.
