You can start by searching on popular fanfiction websites. Use specific keywords like 'Evil Dumbledore' along with related terms like 'Harry Potter' or 'magic' to narrow down the results.
Yes, there are some fanfictions that explore the idea of Dumbledore being evil. Some authors might do this to add a new and unexpected twist to the well - known story. They might question Dumbledore's actions and motives, such as his decisions regarding Harry Potter's upbringing and the way he handled the fight against Voldemort. However, this is a very different take from the original story where Dumbledore is generally seen as a wise and benevolent figure.
One common theme is manipulation. Writers may show Dumbledore as using Harry and others for his own secret ends. Another theme could be misinformation. They might depict Dumbledore as spreading false information to keep control. Also, power - hungry is a theme, where Dumbledore is seen as being after more power than he lets on.
In some fanfiction concepts, Harry might defeat an 'evil' Dumbledore if Dumbledore was secretly under the influence of a dark magic artifact. This could twist his good intentions and lead him to actions that Harry would oppose. Harry, with his strong sense of justice and loyalty, would then fight against this corrupted Dumbledore.
One common theme is betrayal. Since Dumbledore is made evil, Harry feels betrayed by someone he once trusted. Another theme is power struggle. With Harry being godlike, there's a struggle between his new - found power and Dumbledore's devious plans.
I'm not sure about a specific 'godlike harry potter evil dumbledore fanfiction' off the top of my head. But generally, in such fanfictions, the writer might rewrite the plot so that Dumbledore has been manipulating events all along for his own gain, and Harry, with his new 'godlike' powers, has to oppose him. You can try searching on fanfiction websites like Archive of Our Own or FanFiction.net.
Maybe the 'evil' Dumbledore was a future version of himself who had been corrupted by time - travel gone wrong. Harry, not fully understanding the situation, battles and defeats this future Dumbledore. This could then lead to a complex time - paradox plot where Harry has to find a way to fix the timeline and save the real Dumbledore from this fate.
I've read a fanfic where Dumbledore is evil due to a time - travel accident. In the story, a spell during time travel goes wrong and alters Dumbledore's personality. Harry has to figure out what happened and how to fix it. The story is really detailed in exploring how the Hogwarts community reacts to an evil Dumbledore. It shows how the relationships between the characters change and how the power dynamics shift. It's a great read if you like exploring different interpretations of the Harry Potter universe.
A very well - known fanfic in this category is 'Evil Dumbledore: Time Travel Revelations'. This story is popular mainly because it delves deep into the concept of how an evil Dumbledore could have influenced the entire course of the Harry Potter story through time - travel - related events. It also has some great side characters and sub - plots that add to the overall richness of the story.
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.
