Who could be Harry's allies in the 'Harry gets revenge on Albus Dumbledore' fanfiction?

One possible scenario could be that Harry discovers some long - hidden secrets about Dumbledore that he feels were used to manipulate him. So, he might expose these secrets to the wizarding world, ruining Dumbledore's once - sterling reputation. Another could be that Harry uses his own skills and the support of his friends to undermine Dumbledore - related policies or institutions in Hogwarts that he believes were unfair.

Hermione would be a likely supporter. She is always loyal to Harry and if he presented her with evidence of Dumbledore's wrongdoings, she would probably side with him. She has the intelligence to help Harry strategize and find ways to expose Dumbledore. For example, she could use her research skills to dig deeper into Dumbledore's past.

In a 'Harry Potter gets revenge on Dumbledore' fanfiction, Harry could find out that Dumbledore knew about certain threats to his life but didn't do enough to protect him. So, Harry decides to get revenge by undermining Dumbledore's influence at Hogwarts. He might start by convincing the other students that Dumbledore isn't as infallible as they thought. He could do this by revealing some of Dumbledore's past mistakes. Then, he could work on getting the school governors to question Dumbledore's leadership, gradually chipping away at his power and status within the wizarding community.

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.

In certain fanfic ideas, Dumbledore's fingers might hold a significance when it comes to his interaction with Harry. For example, if Dumbledore is using his fingers to trace a pattern in the air while teaching Harry a new charm or defensive technique. It could also be that in a more symbolic way, his fingers represent his guiding influence over Harry, like how a conductor uses their fingers to guide an orchestra, Dumbledore uses his influence (represented by his fingers in a metaphorical sense) to guide Harry through the complex world of magic and the challenges he faces.

Daenerys Targaryen could potentially be an ally. She is open - minded about different powers and has her own dragons. Harry's magic could be seen as another powerful asset. And Jon Snow, being a noble and brave character, would likely welcome Harry's help in the fight against the White Walkers and might offer his own military expertise in return.

For Lily Potter, her husband James Potter might be a likely ally. He would support her in any conflict she has with Dumbledore. Also, her close friends from her school days could side with her. They know her well and would trust her judgment.

One reason could be secrecy. If Harry finds out that Dumbledore has been keeping major secrets from him all along, like about his family or his true role in the wizarding world, he might start to hate him. Another reason could be manipulation. If it seems that Dumbledore has been manipulating Harry's actions for his own gain, that would be a valid cause for hatred in fanfiction.

There may be such extremely non - canon and inappropriate fanfiction out there in the vastness of the internet, but it goes against the original nature and values of the Harry Potter series. J.K. Rowling's world has certain boundaries and this concept is far from what was intended in the original story.

I really like 'Harry Potter and the Hidden Truths of Dumbledore'. In this fanfic, it explores the secrets Dumbledore might have been hiding from Harry all along. It shows a different side of their relationship, with Harry starting to question some of Dumbledore's actions and motives in a way that makes you think.
