In fanfiction, they might even use their connections. They know a lot of people at Hogwarts and in the wizarding world. They could introduce Harry to someone who has important information about the tasks, like an old champion who can give him tips on how to handle the challenges.
Fred and George could help Harry with his studies related to the tournament. Maybe there are spells or potions he needs to learn, and they can tutor him or at least point him in the right direction. Their knowledge of Hogwarts and magic in general could be a great asset to Harry.
One way is by protecting Harry from the bullies. In the fanfiction world, there could be students who are jealous of Harry being in the Triwizard Tournament or just want to cause him trouble. Fred and George, being older and more experienced, can step in and stop any potential harm.
In some fanfictions, Fred and George might help Harry by sharing their knowledge of the Triwizard Tournament tasks. They've been at Hogwarts longer and could have useful insights. For example, they might know secret passages around the areas where the tasks are held.
One common way is through excessive physical harm. Fanfiction authors might write scenarios where Harry is injured much more severely during the Triwizard Tournament tasks compared to the original story. Another way could be isolating him socially even more. For example, having all his friends turn on him because they think he put his name in the Goblet on purpose, which is a much harsher reaction than in the books.
One possible way is through their body language. For instance, Fred might stand with his left foot forward more often, while George has a habit of leaning to the right when he's standing still. Harry, being observant, picks up on these little quirks.
One common way is by using dreams. Fanfic authors may have Harry dream about his memories from 'Goblet of Fire'. For example, he could dream about the Yule Ball and all the mixed emotions he had during that time. This allows the author to delve deeper into his feelings about Cho Chang and his insecurities. Another way is through conversations with other characters. If he's talking to Hermione or Ron, a memory might be triggered and then described in detail to the reader.
Another theme could be growth. Their characters develop over time, learning from their experiences. For instance, they might learn about the importance of loyalty and sacrifice through the events in the fanfiction stories.
Another theme is growth. Harry, Fred and George all grow and change throughout the series. In fanfiction, this can be further explored. For instance, how Harry's leadership skills develop as he teams up with the twins more often, or how Fred and George learn to be more responsible as they get involved in more serious matters with Harry.
One common theme is friendship. In these fanfictions, the bond between Harry, Fred and George is often explored deeply. They support each other through various challenges at Hogwarts or in the wizarding world at large.
Overcoming challenges. Given the dangerous world they live in with Voldemort around, they often have to work together to face and overcome various threats and difficulties. For example, in some fanfictions, they team up to outwit Death Eaters or solve mysterious magical problems that put Hogwarts at risk.
Well, it might be that the Goblet of Fire has been corrupted in the fanfiction. It could be causing chaos in the Triwizard Tournament, endangering the lives of the students more than it should. Harry, being the hero, takes it upon himself to destroy it to restore order. For example, if it starts spawning dangerous and unfair tasks that are clearly not part of the original tournament's design.
In some fanfictions, they could be seen as soulmates in a platonic sense. Their strong bonds of friendship and the adventures they share might be interpreted as a form of soulmate - like connection.
