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.
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.
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.
Another possibility is that it could be Severus Snape in an alternate universe where he becomes headmaster of a different school. He was a complex character at Hogwarts, and seeing how his skills and personality would play out in a different educational setting would be very interesting. He might be more open - minded in a new environment or face different challenges that would test his loyalty and abilities.
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.
There are indeed popular ones. These fanfics often gain popularity because they allow readers to see a different side of the Harry Potter universe. They usually expand on the characters' growth and how the wizarding world changes under Harry's leadership as headmaster. One popular aspect is how he would handle the students who have faced trauma from the previous wars, which really draws in readers.
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 many Harry Potter fanfics, Albus Dumbledore is often still considered one of the best. His wisdom, kindness, and powerful magic made him a great leader in the original series. He was able to guide students, deal with dark magic threats, and keep the school running smoothly.
Albus Dumbledore is extremely popular. His complex character and his long history at Hogwarts make him a prime focus in many fanfics. Severus Snape is also very popular as he has a tragic backstory and his time as headmaster was full of intrigue. Minerva McGonagall is beloved too. She is a strong and wise character, and fanfics often explore more of her leadership and personal side during her headmistress days.
