Reborn as Harry Potter fanfic: How can the character's previous life influence their actions in the wizarding world?

It could be that in the fanfic, Harry Potter discovers some deep - seated secrets about the wizarding world's power structure. Feeling betrayed, he decides to take extreme actions to expose and destroy it. For example, if he finds out that the Ministry of Magic has been using unethical means to control the wizarding population, he might use his influence and magic to bring it all crashing down. He could start by revealing the truth to the public, which could lead to chaos and the destruction of the established order in the wizarding world.

It expands it. Fanfiction often shows new styles of clothing and accessories that weren't in the original books. This makes the wizarding world seem more diverse and full of possibilities in terms of aesthetics.

He gave Harry a sense of purpose. By revealing bits of Harry's past and the prophecy, Dumbledore made Harry understand his role in the fight against the Dark Lord.

One possible reason could be the trauma he has faced. Harry has endured a great deal of pain, from the loss of his parents to the constant battles and threats in the wizarding world. He might want to escape all that and find peace away from it.

A 'Harry Potter World Traveler' fanfic can expand the wizarding world in multiple ways. Firstly, it can introduce new magical locations. Instead of just Hogwarts and Diagon Alley, we get to see enchanted cities in South America or hidden islands in the Pacific. Secondly, it can explore different forms of magic. There could be a type of magic based on music in some far - off land. And thirdly, it can bring in new characters from various parts of the world, each with their own backstories and motives.

Well, Nick Burkhardt has his own set of skills and characteristics from his original story. In the Harry Potter fanfic world, his Grimm abilities could be seen as a sort of magical gift. Maybe he could be a special kind of wizard who can detect dark magic in a different way than the usual spells. He might be an outcast like he was in his own world, but find a new purpose in fighting against the Dark Arts.

They expand it by exploring the teachers' personal lives. For example, a fanfic might show Professor Trelawney's family history and how it affects her divination skills. This adds depth to the world.

No. It's a fictional creation.

Well, Umbridge is not one to tolerate things that go against her idea of order. If she reads fanfic, she could potentially use it as a means to further her control in the fanfic - created wizarding world. For instance, she might see a fanfic that portrays Hogwarts in a different way than she likes and then try to change it back to what she thinks is right. This could lead to a lot of conflict between her and the fanfic creators, as well as the characters within the fanfics who might oppose her actions.

The wizarding world would be in chaos. They would realize too late that they had pinned all their hopes on Harry and neglected him. There would be a great sense of guilt and despair. The Hogwarts students would be shocked and many would feel a deep sense of loss. The teachers might question their own actions and inactions that led to this. The Order of the Phoenix would be in disarray, having lost their main weapon against Voldemort.
