In a fanfiction, Draco could be chosen as an unwilling participant in the Triwizard Tournament. Maybe the Goblet of Fire was tampered with by some dark forces who thought Draco would be an easy puppet. As he goes through the tasks, he starts to show unexpected courage and loyalty, much to everyone's surprise.
Draco as a Triwizard Tournament contestant would bring a different dynamic. His Slytherin cunning could help him in the tasks. However, he may also face internal conflict. On one hand, he wants to win for glory and to show up Harry Potter. On the other hand, he might be afraid of failing and bringing shame to his family. This inner struggle could be a central part of the fanfiction.
Well, a prevalent theme is power. The veela possess a certain kind of power that can either be used against Draco or be harnessed by him in the Triwizard Tournament. This power dynamic is explored in different ways in different fanfictions. Some stories show Draco trying to gain power through his association with the veela, while others show him trying to resist the power the veela have over him to maintain his own identity during the tournament.
There's also a fanfiction titled 'Veela Magic in the Triwizard Tournament: Draco's Story'. It delves deep into how Draco's character develops when he encounters veela magic during the tournament. The author does a great job of exploring his emotions and the magical elements involved. It's really a must - read for fans of this genre.
One possible scenario in this fanfiction could be that Harry and Fleur form an unexpected alliance during the Triwizard Tournament tasks. They might discover they have complementary skills, like Harry's courage and Fleur's elegance and magic related to water (since she's from Beauxbatons). This alliance could lead to them facing the challenges in a new and interesting way, perhaps with Fleur using her Veela charm in a creative manner to distract the obstacles while Harry uses his Gryffindor bravery to take on the more physical parts of the tasks.
There are fanfictions where Hermione and Fleur become friends during the Triwizard Tournament. In some stories, they start to see past their initial rivalries. Fleur might initially see Hermione as just a book - smart girl, but as they face the challenges of the tournament together, they develop a mutual respect. Maybe they work together on the Yule Ball preparations within the context of the tournament, which helps to strengthen their bond.
One great fanfiction could be where Harry and Luna team up in a unique way during the Triwizard Tournament tasks. Maybe Luna uses her off - beat magical knowledge to help Harry solve the puzzles in the maze. For example, she might recognize some magical creatures that Harry is unfamiliar with and guide him through.
One possible fanfiction could be about Harry and Hermione teaming up secretly during the Triwizard Tournament tasks. They might use their combined knowledge and skills to outwit the other competitors. For example, in the maze task, they could have a special code to communicate and find their way to the Triwizard Cup faster than anyone else.
In some fanfictions, the author might explore the idea that the person who dragged Harry into the Triwizard Tournament has a personal vendetta against him. Maybe it's a relative of a Death Eater who wants to see Harry fail publicly or even die during the tournament. Harry then has to not only survive the tasks but also figure out who is behind this plot against him.
