One consequence could be an alteration in the relationships. For example, if he saves Sirius, the relationship dynamics between him, Remus, and the other members of the Order would be different. They might be more united and effective in fighting against the Death Eaters.
The entire Hogwarts structure could change. If he changes something that affects Dumbledore's decisions, the way Hogwarts is run, the classes offered, and the student body's morale could all be different. There could be more focus on certain types of magic or a different way of dealing with students with special abilities.
One consequence could be a butterfly effect. Small changes in the past might lead to big differences in the present. For instance, if Merlin saved someone who was supposed to die, that person could go on to change the political or social landscape of Camelot.
One consequence could be that his relationships change. His friends might not recognize the new 'soul - changed' Harry at first, leading to some initial confusion and distance in their friendships.
The entire world of the story could be altered. Monsters might be stronger or weaker depending on what he changes in the past. If he stops some key event that was related to a monster's origin, it could lead to a different power balance in the world of demigods.
For fanfiction writers, they may have to stop writing and sharing their works. Some might face legal penalties if they are found to be in clear violation of copyright laws.
For fans, it means a loss of creative outlet. Many fans enjoy writing fanfiction as a way to explore the 'Harry Potter' world further, so they are disappointed. For example, a fan who had an interesting idea about a side story for Hagrid can no longer share it in the form of fanfiction.
On the other hand, for the official Harry Potter franchise, it might lead to a more focused brand image. Without the plethora of fanfiction, they can better control how the story and characters are perceived in the public eye. However, it also means losing out on the potential buzz and fan engagement that some positive fanfiction could have generated.
The consequences of inappropriate Harry Potter fanfiction are not to be underestimated. It can alienate a large portion of the fan community. Many fans view the Harry Potter series as something that has positive values like friendship, courage, and love. Inappropriate fanfiction can distort these values. Moreover, in a community that has a significant number of young fans, it can be a form of bad influence. It can also lead to internal conflicts within the fandom, with some fans supporting the creation of all kinds of fanfiction while others believing that inappropriate content should not be associated with the beloved Harry Potter series.
One consequence could be a negative impact on the fan community. It might drive away fans who are uncomfortable with such extreme interpretations. For example, if the fanfiction contains very dark and out - of - character portrayals of beloved characters, it can create a sense of unease among fans who prefer more positive and in - line with the original spirit stories.
He might miss out on important relationships. By isolating himself, he could push away his friends who truly care about him and damage those friendships.
In fanfiction, if Harry Potter is depicted as causing the breach, it could lead to a whole new set of adventures and challenges. It might result in him having to face the wrath of the wizarding world authorities, like the Ministry of Magic. He could be on the run, trying to clear his name and figure out how to fix the mess he supposedly made.
