One interesting plot could be a character who is an underdog in the academic Triwizard Tournament. They might not be as well - known or as powerful as the others at first. But through their hard work, they discover a unique magical ability that gives them an edge in the challenges. For example, they could have a special connection to an ancient magic that helps them solve a difficult riddle in one of the tournament tasks.
One common plot is Hermione being an unexpected champion. Maybe she gets chosen by the Goblet of Fire due to some magical interference or a misunderstanding. Another plot could be her facing unique challenges during the tasks. For example, in some fanfictions, she uses her vast knowledge to outwit the challenges in a different way than the original champions. Also, there are often plots where Hermione has to deal with the jealousy and suspicion of her peers, since she's not supposed to be in the tournament in the first place.
Hermione Granger is often a popular character. Her intelligence and love for learning make her a natural fit for the academic aspect of the Triwizard Tournament. She can be portrayed as using her vast knowledge of magic to outwit her opponents in the various tasks.
One idea could be to cross it with the world of Narnia. Imagine the Triwizard champions having to face challenges in the magical land of Narnia. They might have to deal with the White Witch's minions or find their way through the enchanted forest. Another idea is a crossover with the Percy Jackson universe. The demigods could participate in the Triwizard Tournament, bringing their unique powers and abilities. For example, a son of Poseidon might use his water - controlling powers in a water - based task.
Maybe in the fanfiction, there's a plot twist where Hermione discovers a hidden rule in the Triwizard Tournament that allows her to form an alliance with all the champions instead of competing against them. This would change the whole dynamic of the tournament and lead to a completely different kind of story.
A really cool plotline could be that the Triwizard Tournament tasks are all connected to an ancient prophecy that only Harry and Susan can figure out. They start to notice strange symbols during the tasks that lead them on a hunt through Hogwarts' secret passages to uncover the truth behind the prophecy.
One common plotline is that Hermione participates in the Triwizard Tournament instead of Cedric. This gives her and Harry a whole new dynamic as they face the challenges together. Another plotline could be that there's some sort of magical interference during the Tournament that makes Harry and Hermione realize their deeper feelings for each other. For example, a spell gone wrong that makes them share their innermost thoughts.
One idea could be a different champion from an unexpected school. For example, a small wizarding school in a far - off land sends a champion. This champion could have unique magic abilities that are not common in Hogwarts, Beauxbatons, or Durmstrang. They might use magic related to nature in a very different way, like communicating with magical plants to solve tournament tasks.
One idea could be that Natsu enters the Triwizard Tournament and has to face off against some really tough opponents from different magical guilds. His dragon - slayer magic causes all kinds of chaos during the tasks.
One idea could be a story where a new, unexpected champion enters the Triwizard Tournament. Maybe a student from a different magical school that we haven't heard of before. This new champion could bring unique magic and challenges to the tournament, causing all the other champions to have to adapt their strategies.
A common plotline is that of Hermione and Fleur teaming up against the other competitors. This is interesting as it subverts the expected rivalry. They can use their combined strengths to overcome challenges that neither could face alone. For example, Hermione's strategic thinking paired with Fleur's beauty - based magic can be a formidable combination in tasks like the maze.
