Obviously, Dumbledore would be one of the main characters since it's about exposing him. Harry Potter might also be a key character as he was so closely related to Dumbledore in the original series.
In some cases, new characters could be introduced in the fanfiction. They could be characters who have some connection to Dumbledore's past that is being exposed. For example, a long - lost relative or an old acquaintance who knew Dumbledore when he was younger and can provide insights into his character that were previously unknown. But in general, Dumbledore and Harry are likely to be central to the story.
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.
The 'harry potter exposed dumbledore fanfiction' might deal with events or decisions that Dumbledore made which were not fully explored in the original books. For example, his relationship with Grindelwald and how that influenced his actions later. It could also explore his sometimes morally ambiguous choices, like how he used Harry as a tool in the fight against Voldemort without fully disclosing all the details to him. Fanfiction often takes the existing characters and world and delves deeper into their stories.
Ron could also be there. He might be a bit jealous at first of Harry's special relationship with Dumbledore but then comes around and supports Harry in his adventures as an apprentice. There could be some great scenes of their friendship evolving in this new context.
The main characters would be Harry and Dumbledore. However, the antagonists could also be important. If there is a new dark force in the fanfiction, they would be the ones Harry and Dumbledore are up against. Voldemort's remaining followers could also be part of the equation. Their actions could be what drives Harry to submit to Dumbledore's leadership, as they pose a significant threat to the wizarding world and Harry realizes he needs Dumbledore's guidance to face them.
Well, obviously Harry Potter. He's the main protagonist in the original series and in the bashing fanfictions, he might be the one to finally see through Dumbledore's facade. Ron Weasley could also be popular. He's Harry's best friend, and in these stories, he might support Harry in his doubts about Dumbledore. And then there's Voldemort. Some fanfictions might use Voldemort as a tool to show how Dumbledore's actions or inactions affected the battle against him. For example, if Dumbledore was so secretive, it could have made it easier for Voldemort to gain power.
The Weasley family as a whole might also support Harry. They have always treated Harry like one of their own. Arthur Weasley, being an open - minded wizard, might understand Harry's perspective. Ginny, who is very close to Harry, would surely be on his side as well. They would see Harry as more than just a student defying a headmaster, but as someone fighting for what he believes is right.
Hermione would be a likely candidate. She is Harry's best friend and is very intelligent. She could use her knowledge of spells and magic to come up with a plan to help Harry escape. For instance, she might create a diversion or find a way to disable the security around Dumbledore's area.
For Harry, his friends like Ron and Hermione are likely to be his allies. They've always been by his side through thick and thin in the original series, so it's natural for them to support Harry in a confrontation with Dumbledore. Neville could also be an ally, given his growth and courage shown in the books.
Snape can be a prominent character. Given his complex relationship with Dumbledore and Harry, his perspective could add a lot to the story. He might have some insights into Dumbledore's actions that Harry doesn't know about, and his reactions to Harry's blaming could vary from being scornful to having a moment of understanding. Luna Lovegood could also be a part of it. Her unique view of the world might make her offer some different viewpoints on the situation between Harry and Dumbledore.
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.
