One idea could be a crossover adventure where Naruto accidentally enters the world of Lucoa. They could team up to face a common enemy that threatens both their worlds. Naruto's ninja skills combined with Lucoa's dragon powers would make for an exciting story.
There isn't a widely known and clearly defined 'love story' in the traditional sense between Kukulkan and Quetzalcoatl in a single unified narrative. However, both are important deities in Mesoamerican cultures. Kukulkan was a Mayan deity often associated with snakes and the sky. Quetzalcoatl was a significant Aztec deity, often depicted as a feathered serpent. They share similarities in their serpent - like forms and their connection to important aspects of the cosmos, but there is no common, well - established love story between them.
I'm not sure specifically as there could be many different takes on this. It might be about Percy being in a dangerous situation and Quetzalcoatl, a powerful figure from mythology, coming to his rescue in the context of a fan - created fictional story.
Another great Lucoa fanfic might involve her forming an unlikely friendship with a character who is initially afraid of her. As the story progresses, they learn from each other and overcome their differences. This could show Lucoa's kind and patient side as she helps the other character see that she's not as scary as she seems.
In a fanfiction, Harry as a Quetzalcoatl Animagus could play a crucial role in a battle against Voldemort. His Animagus form could be resistant to certain dark spells, and he could use the large size and strength of the Quetzalcoatl to his advantage. Maybe he could also communicate with magical creatures from the Americas that are drawn to his new form, and they could help in the fight against the Death Eaters.
It's likely that the main characters from the original 'Highschool DxD' series would still play important roles. Maybe Issei Hyodo would be there, adapting to the new quetzalcoatl - influenced environment.
There's no way to know for sure who the author is without more information. It could be anyone who is a fan of the relevant source material (maybe Percy Jackson series) and has an interest in Quetzalcoatl from mythology.
In some of these fanfictions, there could be a focus on the mythology of Quetzalcoatl integrated into the Highschool DxD universe. This could lead to exciting tales where the characters have to face off against threats related to this ancient mythology while also dealing with the typical high - school drama and the battles that are characteristic of the DxD world. There might be new magical abilities or artifacts inspired by Quetzalcoatl that change the course of the story.
Well, having a Quetzalcoatl as a familiar would be extremely powerful for Harry. A Quetzalcoatl is a mythical and magnificent creature. It could help Harry in many ways, like flying faster than a broomstick, and its magical abilities might be beyond what we've seen in the regular 'Harry Potter' world. Maybe it could sense danger from afar and protect Harry more effectively.
Another plot point might be Lucoa sharing her dragon - related knowledge with the ninja. This could lead to new jutsu being created or new ways of thinking about power in the Naruto universe. For example, she might teach about dragon - like breathing techniques that could be incorporated into ninja training.
