was dumbledore bad

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.

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.

It could be that Dumbledore has a day filled with magical mishaps, difficult decisions, or run-ins with powerful foes. Maybe his spells don't work as expected or there's a big misunderstanding at Hogwarts that he has to sort out.

There's also a chance that Dumbledore gets caught by a group of rogue magical creatures. For instance, if he was exploring an area that was supposed to be off - limits to wizards and the creatures there saw him as an intruder. They might not be as rational as wizards and could hold him captive without really understanding who he is.

Well, it could be that Dumbledore has some sort of hidden device or spell that he activates when kidnapped. For example, he could have a charmed object that sends a signal to his allies, like the Order of the Phoenix. His allies then come to his rescue and he manages to escape during the chaos. Also, Dumbledore is extremely intelligent. He might outwit Grindelwald by engaging him in a complex conversation full of riddles and misdirections, which gives him an opportunity to break free.

It could be Severus Snape. He has a complex relationship with Dumbledore. Maybe Snape discovers some of Dumbledore's plans that he doesn't agree with regarding Harry Potter. He then sends a Howler in a fit of anger to express his disapproval.

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.

Fred and George Weasley are very likely candidates. They are known for their love of pranks and their mischievous nature. They might see pranking Dumbledore as the ultimate challenge.

I'm not sure of a specific fanfic with this exact premise off the top of my head. However, you can try searching on fanfic websites like Archive of Our Own or Fanfiction.net. Use keywords like 'Harry Potter', 'Strong Smart Character', 'Anti - Dumbledore'. There are thousands of fanfics out there, and you're likely to find one that fits this description.

One possibility is that the character might be a Slytherin student who has his own ideas about power and knowledge. They could see Dumbledore's actions as being too self - righteous. This character, being strong and smart, might try to undermine Dumbledore's influence within the school. They could start by spreading rumors about Dumbledore's past decisions that they think were wrong. For example, they might question Dumbledore's handling of the Chamber of Secrets incident, believing that Dumbledore should have been more proactive in preventing it rather than just reacting after the fact.
