They differ in terms of the relationships he has with other characters. In canon, he has a mentor - like relationship with Harry. However, in fanfics that hate him, this relationship can be completely flipped. Harry might see Dumbledore as an enemy or at least a very untrustworthy figure. The other characters' reactions to Dumbledore also change. They might be more critical or even actively oppose him, which is a big departure from the original where most characters respected him to a large extent.
The fanfictions that hate Dumbledore differ from the canon in the way they explore the consequences of his actions. In the books, the focus is more on the main plot against Voldemort. But in these fanfics, the writers dig deeper into the side - effects of Dumbledore's decisions. For instance, how his actions affected the lives of minor characters, like the students at Hogwarts. They might show that Dumbledore's actions had a more negative impact on the overall well - being of the wizarding community than was shown in the original story, which mainly focused on the fight against the Dark Lord.
Fanfictions that hate Dumbledore often deviate from the canon in how they portray his character's intentions. In the canon, Dumbledore is generally seen as a wise and benevolent figure, albeit with some flaws. But in these fanfics, his actions are often painted as more self - serving. For example, his actions towards Harry might be shown as being more about his own legacy or power plays rather than protecting the wizarding world as in the original story.
Some fanfictions portray Dumbledore negatively because he made many controversial decisions in the original series. For example, his handling of Harry Potter's situation was sometimes seen as using Harry as a pawn in the fight against Voldemort. He kept many secrets from Harry that could have potentially changed the course of events and put Harry in more danger. Also, his relationship with Grindelwald in his youth and the events surrounding it add to the reasons why some writers in fanfics might choose to show him in a negative light.
It could be that Harry finds out about Dumbledore's secrets regarding the Deathly Hallows. If Harry thinks Dumbledore was more interested in the Hallows for his own purposes rather than for the greater good, it might make him hate Dumbledore.
In some fanfics, Harry might hate Dumbledore because he feels Dumbledore has been using him all along as a tool to defeat Voldemort. Dumbledore has been making decisions for Harry without fully considering Harry's feelings and desires. For example, he didn't tell Harry about the prophecy until it was almost too late, and Harry might see this as a form of manipulation.
In some fanfictions, female Harry Potter might hate Dumbledore because the author wants to create a different dynamic. Maybe Dumbledore's actions in the original story, like keeping secrets from Harry, are exaggerated in the fanfic. For example, if he withheld information that could have saved someone she cared about, it could lead to her hatred.
One reason is that fans like to explore different perspectives. In the original books, Dumbledore is presented as a wise and mostly benevolent figure. But some fans want to see what would happen if he had a darker side. It adds a new layer of complexity to the story.
These fanfictions often make Dumbledore seem less of a benevolent figure. Instead of being the wise and all - knowing mentor, he becomes a character with his own self - interests. They show that his actions towards Harry, like putting him in dangerous situations, might not be just for the greater good but for his own plans.
Well, in some fanfictions, Dumbledore is bashed because writers want to explore alternative storylines. They might believe that Dumbledore was too controlling. He made a lot of decisions for Harry without really consulting him. So by bashing him, they can create scenarios where other characters step up or Harry has a different kind of growth without Dumbledore's influence.
Some fanfictions focus on Dumbledore's mistakes in raising Harry. They might show that his distance and secrecy were not just for protection but rather a sign of his lack of true care. For example, in a particular fanfic, Dumbledore is blamed for not being more forthcoming with information about Harry's parents and the prophecy, which leads to Harry making many mistakes and facing more danger than necessary.
There's 'Dumbledore's Special Training for Harry' which focuses on combat training. Harry learns advanced dueling techniques from Dumbledore, which comes in handy when facing powerful dark wizards. It also shows how Dumbledore prepares Harry for the greater challenges that lie ahead in the wizarding world.
One example could be those where Dumbledore is portrayed as having hidden motives that are not in the best interest of Harry or Hogwarts. In some fanfictions, he might be shown as being overly manipulative in his actions towards Harry, like using him as a pawn in a bigger game against Voldemort without fully considering Harry's well - being. However, it's important to note that these are just creative interpretations in the world of fanfiction and not the official view of the character from the original books.
