Well, in certain Harry Potter fanfiction, Dumbledore can come across as insane. It really depends on the writer's interpretation and the direction they want to take the story. Some might do it for shock value, to create a more edgy or different take on the well - known character. However, the canonical Dumbledore was a highly intelligent and calculating figure, not insane.
It might make Harry more confident. With Dumbledore's training, Harry gains more knowledge and skills, which gives him the confidence to face challenges.
Well, Harry might outsmart Dumbledore by using his unique understanding of the magical world in ways Dumbledore doesn't expect. For example, Harry has a more direct experience with some dark magic items due to his encounters with Voldemort. He could use this knowledge to make decisions that seem counter - intuitive to Dumbledore but are actually more effective in a particular situation.
He might give Harry detention. Harry could be made to clean the trophies in the trophy room or help Hagrid with some difficult tasks in the Forbidden Forest under strict supervision.
One possible reason could be that Harry breaks school rules in the fanfiction. For example, if he ventures into the Forbidden Forest without permission. Dumbledore is strict about the safety of students and such disobedience might lead to punishment.
Often, Dumbledore as Death would be a very complex character. He may not be the straightforward evil or good. His role might be more about maintaining a balance in the wizarding world, which is similar to the concept of Death in some mythologies. He could be using his influence on the different characters in different ways. For instance, his relationship with Snape could be a part of his plan as Death. Snape's actions, which were so crucial in the original story, might be reimagined as being directly or indirectly guided by Dumbledore - as - Death. This could add a whole new layer of mystery and intrigue to the fanfiction.
No. This is a very unorthodox concept that is not likely to be popular in the mainstream Harry Potter fanfiction world. Most popular fanfictions tend to follow more traditional storylines like the battle between good and evil, or the relationships between the main characters.
Well, it might be a fanfic where a new dark wizard emerges with a unique power to manipulate memories, and they target Dumbledore's memories of Harry Potter. Or it could be a story where Dumbledore gets caught in a complex web of magical experiments gone awry, leading to this memory loss.
In a fanfiction, Dumbledore might steal out of desperation. Suppose there was a situation where a curse was about to be unleashed on Hogwarts, and the only way to stop it was by stealing a particular ingredient for an antidote from a place where it was not supposed to be taken. Dumbledore, seeing no other option, decides to steal it. His motive here is to save the school and its students, even if it means breaking the rules.
Hermione could be a main character. She might use her vast knowledge to help Harry and Dumbledore in their adventures. For example, she could research ancient spells or potions that are crucial for their mission.
