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.
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.
One common theme is the exploration of gender roles. Since Harry is female in these fanfictions, it often looks at how she navigates a world that was originally written with a male protagonist in mind. For instance, how she deals with the expectations of others during the tournament.
In some fanfictions, Draco might provide crucial information or clues to Harry that help him navigate the challenges of the tournament.
One common theme is the exploration of a new relationship dynamic. Since veela have their own cultural and magical aspects, it changes how Harry and Draco interact with each other. For example, the idea of nesting might involve a sense of protection and building a home together in a very different way than in regular wizarding relationships.
One common theme is the exploration of an unexpected relationship. Since Harry and Draco were enemies in the original series, a Veela - related pregnancy forces them to reevaluate their feelings for each other. Another theme is the dealing with the consequences of a magical pregnancy. It often involves how they adapt to the changes in their bodies and lives due to the Veela nature. And also, themes of acceptance, both from themselves and from the wizarding world around them are quite common.
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.
