Yes, there might be such fanfictions out there. Fanfiction writers often create crossovers where they put characters from different universes like Naruto and High School DxD together and come up with various scenarios, including ones where Naruto could potentially 'kill' a character from the DxD universe. However, the quality and nature of these fanfictions can vary greatly.
The plot could involve Naruto arriving in the DxD world with his goal - seeking nature intact. He realizes that the power dynamics here are very different from his own world. He starts to learn about the different races and their powers. As he is seen as a god, he is constantly challenged by various powerful beings. He uses his wisdom from the ninja world and his growing understanding of DxD to resolve conflicts and perhaps find a way back home while also making a positive impact on the DxD world.
There could be. Fanfiction writers are known for their wild and creative ideas. Since both Naruto and High School DxD are popular series, someone may have written a fanfic where Naruto is presented as a god - like figure within the High School DxD universe. This could add an interesting twist to the story, perhaps bringing in Naruto's unique powers and abilities into the High School DxD world.
In some Highschool DxD and Naruto crossover fanfictions, Naruto might be depicted as a god - like figure. This could be due to his extremely powerful abilities in the Naruto universe, such as his vast chakra reserves, multiple jutsu, and his status as a hero in his own world. Writers may take these aspects and amplify them in the Highschool DxD setting, where the power levels and the concept of beings with god - like powers already exist. So, it's possible for Naruto to be seen as a god in such fanfictions.
One interesting idea could be the fusion of Naruto's ninja abilities with the supernatural elements from High School DxD. For example, Naruto's shadow clone jutsu combined with the devils' powers in DxD could create some really cool battle scenarios.
The uniqueness lies in the combination of two very different universes. Naruto has his own set of ninja powers and a distinct backstory, while Highschool DxD has its own supernatural elements. When combined, it creates a whole new world of possibilities. For example, Naruto's jutsu could be used in a way that surprises the characters in the Highschool DxD world, and vice versa.
One interesting concept could be the fusion of the Naruto and High School DxD universes. For example, seeing how Naruto's ninja skills would interact with the devil - based powers in DxD. Maybe Naruto characters using their chakra in the DxD world to fight against devils or angels in new and unexpected ways.
The combination of two popular franchises. Naruto has a huge fanbase and so does DxD. Merging them in a fanfiction, especially with the 'god' element, creates a unique and exciting concept.
If Naruto was a god in Highschool DxD fanfiction, he would likely change the power dynamics completely. His abilities could overpower many of the existing characters in the Highschool DxD universe. For instance, his speed and strength, enhanced by his god - like status, would make him a formidable opponent in battles. He might also attract a lot of attention, both from the good and the bad characters in the story, as his power would be a great asset or a threat.
One main theme is power and adaptation. Since Naruto is coming from his own world into the DxD universe, he has to adapt his powers and skills. And as a primordial god - like character in some of these fanfics, his new - found power is a major aspect that drives the story.
