Another consequence could be that he has to face opponents in the tournament that are far more experienced or dangerous than he expected. In fanfic, the author might make these opponents even more formidable to test Harry in ways that the original tournament didn't. Also, his relationship with Cedric could be severely strained as they are now direct competitors, which could lead to some intense rivalries and emotional drama.
One consequence could be that he gets into trouble with the school authorities. They might suspect foul play and start an investigation into how he managed to fool the Goblet.
On the other hand, not competing might lead him to find alternative paths. He could start his own non - competitive projects or groups, which could have a big impact on the fanfic's community in a different way. For example, he could form a study group for magic that focuses on sharing knowledge rather than competing for grades or status.
As the plot progresses, Harry might start to realize the true extent of what he's gotten himself into. He could face internal struggles, doubting his decision. Maybe he'll discover some secrets about the Goblet or the tournament that he wasn't supposed to know. This could lead to a whole new set of challenges and adventures, like having to deal with dark magic associated with the tournament that was hidden from the public.
If he stabs himself in a non - vital area, he might survive but be severely weakened. This could lead to him having to rely on his friends more for protection and support, changing the dynamics of their relationships.
One consequence could be a split in the friendship group. If Harry hates Ginny, Ron, being Ginny's brother, would be in a difficult position. It could lead to a divide between Harry and Ron as well.
Well, in the 'ginny cheats on harry fanfic', a consequence might be that Ginny loses the trust of those around her. Harry might become more guarded in future relationships. Their families would also be affected. For example, the Weasley family might have to deal with the fallout and try to understand why Ginny did such a thing. And Ginny herself could end up feeling very guilty and regretful.
He might avoid any events or communities related to magic fanfic. He won't be interested in reading or discussing them.
One possible consequence could be that he'd be seen as a rule - breaker on a whole new level. The Goblet of Fire is a very important magical object in the wizarding world. Its destruction might lead to chaos in the Triwizard Tournament. For example, the tasks could become unstructured or the magic binding the tournament together could start to unravel.
It might lead to a rift between Hogwarts and the other schools involved in the tournament. They could see Harry's actions as an act of aggression or a way of cheating, since the Goblet is such an important part of the event. However, if Harry can prove that the Goblet was corrupted or dangerous, they might come around. In the fanfiction, this could lead to a whole new set of diplomatic relations between the wizarding schools that need to be explored and resolved.
In the fanfic, Harry might use his quick thinking and knowledge of magic. He could trick the Goblet by using spells to misdirect its selection process. For example, he might create an illusion of another person's identity so the Goblet chooses based on false information.
