Well, in Harry Potter fanfic, the Triwizard Champions could be a whole mix of different characters. Sometimes, authors might create alternate versions of the original champions. For example, they could make a character who was overlooked in the original story become a champion. It could also include characters from different magical schools that are not part of the canon Triwizard Tournament, like a school from a far - off land. Or perhaps a character who has some special power or ability that makes them stand out as a champion in the fan - created story.
A really cool plot twist in Harry Potter fanfic regarding the Triwizard Champions could be that the champions from different schools end up switching places. So the Hogwarts champion has to compete for Beauxbatons and vice versa. This would lead to a whole new set of challenges and interactions. They would have to adapt to different magical cultures and teaching styles while still competing in the tournament. Also, it could be that one of the champions is actually an animagus and uses their animal form to gain an advantage in the tasks in a very unexpected way.
Fleur Delacour is quite popular too. Her beauty and her status as a Beauxbatons champion make her a fascinating character to write about. Many fanfictions explore her relationship with the other champions, especially Harry. Additionally, Hermione Granger often plays an important role in these fanfictions. Her intelligence and her friendship with Harry mean she can be involved in many different storylines related to the Triwizard Tournament, like helping the champions prepare for their tasks.
One interesting storyline could be a deeper exploration of the relationship between the Triwizard champions outside of the tournament tasks. For example, how they might support or secretly envy each other. Another could be a fanfiction where the tasks are altered in some creative way, like a new magical creature being introduced in the first task. And some might focus on the backstories of the champions, like what Cedric Diggory was really thinking and feeling during the whole process.
In a fanfic like this, there could be a lot of drama. For example, Pansy might be conflicted because of her Slytherin loyalty and her growing feelings for Harry. Harry, on the other hand, could be dealing with his own feelings while also trying to survive the dangerous tasks of the Triwizard Tournament. Their relationship could start with a lot of bickering and then slowly turn into something more romantic as they face the challenges together.
It's hard to say without reading the fanfiction. They could be the Triwizard champions like Cedric Diggory, Fleur Delacour, and Viktor Krum. Or it could be some new champions created specifically for this fan - made story.
Another plot could revolve around a spell gone wrong during the Triwizard Tournament tasks. For example, the spell that creates the maze for the final task malfunctions and the maze becomes a living, sentient entity that changes and adapts to the champions' movements, making it much more difficult and dangerous to navigate.
There might be a fanfic where during the Triwizard Tournament, Harry gets cursed and Hermione has to find a way to break the curse. She races against time, using every spell and potion she knows. Meanwhile, she also has to deal with the tournament tasks on Harry's behalf. In the end, through her determination and love for Harry, she manages to break the curse and they both complete the tournament in an unexpected way.
I'm not entirely sure as there could be many different interpretations. It might be about how Harry Potter is safeguarded by the champions in some sort of alternate scenario within the fan - created story.
