One possible reason could be that Harry has grown tired of the cycle of violence. He might have seen how much destruction the fight has already caused and decides that there has to be another way. Maybe he believes that by refusing to fight, he can break the pattern and find a more peaceful solution to end Voldemort's reign of terror.
The plot would take a huge turn. For one, the Order of the Phoenix and Dumbledore's Army would be in chaos as they were relying on Harry to be the one to take on Voldemort. They would have to re - evaluate their entire strategy. Instead of a straightforward battle - oriented plot, it might shift towards a more diplomatic or psychological struggle.
It could be that he has some personal traumas related to fighting. For example, he might have seen the negative consequences of fighting in the past, such as the loss of loved ones or destruction of places he cares about, so he refuses to engage in it. In addition, he may also be influenced by certain moral or ethical beliefs within the context of the fanfic's world, which lead him to oppose fighting.
Hermione could be the main character. She is extremely intelligent and powerful in her own right. She might use her vast knowledge of magic to find a solution that doesn't involve Harry fighting Voldemort. For example, she could discover a way to rewrite the rules of magic that govern Voldemort's power.
It could also be that Harry Potter in fanfiction is a more self - reflective version of himself. He has already been through so much in the original series that he has grown tired of fighting. He may realize that there are other ways to resolve conflicts, such as through dialogue and understanding, rather than resorting to physical or magical combat as is often depicted in fanfiction.
It means that Harry has a negative attitude towards fanfic. Fanfic is fan - written fiction based on existing works. Harry might refuse it because he values the integrity of the original work. He could also be worried about legal issues associated with fanfic, such as copyright infringement. Additionally, he may not like the idea of others taking creative liberties with something he is associated with.
Some fans might be disappointed as they expect action - packed scenarios with Harry Potter fighting. It could lead to a decrease in the popularity of certain fanfictions that rely on such battles.
I'm not sure if there is such a fanfic. Fanfics cover a wide range of themes and scenarios, but this particular one might be quite rare or even violate some of the general guidelines of the Harry Potter fanfic community. Many fanfic platforms have rules against inappropriate or non - canon - compliant content.
There probably is. Fanfic communities are full of unique and unexpected plot ideas. This kind of plot would completely turn the original story on its head. It might involve some sort of alternate reality where Harry and Voldemort have a common goal or where they are forced to work together due to some external threat. It could be a really interesting read for those who like exploring different interpretations of the Harry Potter universe.
