The fanfiction where Dumbledore trains Harry can impact the universe's politics as well. If Harry is trained to be a more powerful wizard, he could have a greater influence on the Ministry of Magic. He might be able to push for reforms or changes in the way magic is regulated. Moreover, it can affect the way the wizarding world views Hogwarts. If Dumbledore is seen as training a super - powerful Harry, Hogwarts could be seen as an even more important place for the development of great wizards. This could lead to more competition among students to get into Hogwarts and more prestige for the school.
In terms of character development, it has a huge impact. Harry can grow in ways that were not possible in the original series. If Dumbledore trains him in mental magic like Legilimency, Harry becomes more self - aware and better able to understand others' motives. This can lead to different relationships. For instance, he might be more suspicious of some characters or more trusting of others. It also gives a new perspective on Dumbledore's role. He is not just a headmaster but a more hands - on mentor, which changes how we view his character in the overall Potter universe.
He might give Harry detention. Harry could be made to clean the trophies in the trophy room or help Hagrid with some difficult tasks in the Forbidden Forest under strict supervision.
It can change the perception a great deal. By showing Harry as tortured and broken, it adds a layer of darkness to the generally more hopeful and adventurous world of Harry Potter. It makes readers realize that there are more sinister aspects that could have happened within the wizarding world.
It might make Harry more confident. With Dumbledore's training, Harry gains more knowledge and skills, which gives him the confidence to face challenges.
It shakes the foundation of the trust that fans have in the characters. Dumbledore is often seen as a wise and benevolent figure. If Harry destroys his reputation, it makes fans question all the previous events and decisions that Dumbledore was involved in. For example, his guidance to Harry might now seem suspect.
In the original Harry Potter series, Harry would never kill Dumbledore as they had a strong bond. However, in fanfiction, the author might rewrite the story by having Harry be under the influence of a powerful dark magic or a powerful mind - controlling spell that forces him to do so. Another possibility could be a huge misunderstanding where Harry thinks Dumbledore has turned evil and poses a great threat to Hogwarts and the wizarding world.
On the other hand, it might create some controversy among fans. Some fans might think that bashing the Muggle military is unfair or inaccurate. They might believe that the Muggle military has its own strengths and that the fanfiction is creating an unbalanced view of the relationship between the two worlds. This can lead to discussions and debates within the fan community, which in turn can shape different perspectives on the Harry Potter universe.
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.
In my opinion, Dumbledore would underestimate Harry Potter fanfiction. Fanfiction is a realm where fans take the original story and run with it in all kinds of directions. There are fanfictions that change the personalities of characters, create new storylines that deviate greatly from the original. Dumbledore, who is bound by the original narrative and his role in it, may not understand the significance of this new wave of creativity that fanfiction represents. He may see it as a distortion of the world he knows rather than a celebration and expansion of it.
Hermione would be horrified. She would immediately start trying to figure out a way to rescue Harry. She might start researching in the library for some ancient spells or forgotten magic that could help. Ron would be angry at Dumbledore and would probably want to rush off to save Harry without much of a plan at first.
Perhaps Harry Potter could screw over Dumbledore in fanfiction by revealing some of Dumbledore's past mistakes or misdeeds to the wizarding community. If there are things Dumbledore has done in his past that are morally gray or controversial, and Harry decides to expose them, it would definitely cause problems for Dumbledore's reputation and his standing in the wizarding world.
