It completely flips the power structure. Normally, Dumbledore is seen as one of the most powerful wizards in the original series. But in this fanfiction, Harry being more powerful means that the traditional hierarchy is disrupted. For example, battles and challenges that Dumbledore would usually handle might now be Harry's domain.
Maybe in this fanfiction, Harry has a hidden power within him that is only revealed later. It could be something related to his family heritage that Dumbledore doesn't possess. Also, the author might have decided to give Harry more power to explore different storylines. For instance, Harry could be more powerful because he has a stronger bond with the magical creatures, which gives him additional powers that Dumbledore lacks.
It might make Harry more confident. With Dumbledore's training, Harry gains more knowledge and skills, which gives him the confidence to face challenges.
Harry may show greater power in his connection to the magical world around him. He has always had a special bond with Hogwarts. In the fanfiction, this bond could be enhanced. So, when Voldemort tries to attack the school, Harry is able to draw on the magic of Hogwarts itself. He can use the ancient magic stored within the castle walls to create powerful shields and offensive spells that are far more potent than anything Voldemort can muster.
He becomes more nurturing. Dumbledore, who was mainly seen as a wise leader, now has to be a caregiver. He might show more patience and tenderness as he takes on the role of a father to Harry.
The relationship would become very strained. Harry's rejection would likely make Dumbledore re - evaluate his actions and how he has interacted with Harry. Dumbledore might be shocked at first, since he probably thought Harry was on the same page as him most of the time.
The fanfiction might show a more adversarial relationship. Harry could start to oppose Dumbledore's plans instead of following them blindly. This is very different from the original where Harry was mostly compliant. For example, in the original, Harry accepted Dumbledore's tasks like finding the Horcruxes, but in the fanfiction, he might question the motives behind these tasks and resist them.
Well, Harry's character development could be quite complex. He might initially be shocked or even angry when he 'turns on' Dumbledore. As he delves deeper into his new feelings, he could start to question his own beliefs and values that were influenced by Dumbledore. This could make him explore different magical paths or ways of fighting against Voldemort. For example, he might look into more radical or unorthodox methods instead of relying on Dumbledore - inspired strategies.
The excessive power of Harry in this fanfiction can lead to a different character development. In the original series, Harry had to struggle, face failures, and learn from his mistakes. But here, with his over - the - top power, he might not experience such growth. His relationships with other characters could also change. For instance, his friends might become more like sidekicks rather than equal partners in adventure because he can handle most things on his own, which is a huge departure from the original story's charm and depth.
In many 'harry potter super powerful fanfiction', the power - up of Harry (or other characters) often changes the power dynamics in the story. For example, if Harry is super powerful, he might not need the help of his friends as much, so the strong bond of friendship that was central in the original story could be weakened. Also, the villains would have to be much stronger or use different tactics to oppose him. The challenges he faces become different, not just the typical duels and mysteries but perhaps more on a cosmic or world - changing scale.
Dumbledore, as Harry's guardian in the fanfiction, would probably use his influence in the wizarding world. He could make sure that Harry is taught by the best teachers at Hogwarts. He'd also be there to offer advice and guidance, especially when Harry faces challenges like dealing with Voldemort or other dark forces. For example, he might teach Harry some advanced defensive magic privately to better protect himself.
