Well, first of all, the story would take a very different turn. Naruto, as a god, would have access to unlimited chakra probably. In the Highschool DxD world, this would mean he could perform his most powerful jutsu without any limitations. He could also probably influence the politics and power struggles in the underworld and among the angels and devils. His presence would be a major disruption, and the other characters would either have to ally with him or try to defeat him. And his values from the Naruto world, like his sense of justice and friendship, would also impact the way he interacts with the characters in Highschool DxD.
If Naruto were a god in Highschool DxD fanfiction, it would be chaos at first. The normal order of the Highschool DxD world is based on a certain power structure among devils, angels, and fallen angels. Naruto's sudden appearance as a god would shatter this. He could use his god - like powers to, say, teach new ways of combat or chakra control to the characters in Highschool DxD. His very existence would make many of the power - hungry characters either jealous or eager to gain his power. And his backstory from the Naruto world would add a whole new layer of complexity to the fanfiction, as his experiences there would shape his actions in the Highschool DxD world.
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.
It would probably be really interesting. Naruto's skills and abilities as a 'god' would likely disrupt the normal flow of the Highschool DxD world. Maybe he'd use his ninja techniques in battles against the devils and angels in that universe.
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.
A really interesting fanfiction could be where Naruto's Nine - Tails chakra has an unexpected reaction when he is near Moka. Maybe it flares up in a way that he can't control at first, and Moka's vampire instincts sense the power. This could lead to a situation where they have to work together to figure out how to control this new interaction between their powers. Also, Naruto could introduce the concept of ninja teams to the characters in Highschool DxD, which could change the way they approach battles and group activities.
Well, in such a fanfiction, Naruto might feel out of place in the Highschool DxD world. He could be heartbroken because he misses his friends from Konoha. Maybe he has a hard time adjusting to the different rules and powers in the new world.
If Naruto was the Son of God in a Highschool DxD fanfiction, his character development would be really interesting. He'd have to adapt to the new world with its different rules regarding magic, power levels, and social hierarchies. His relationships with the characters in DxD would also be a key aspect. For instance, how would he interact with Rias? Would they form an alliance? Or would there be some sort of romantic tension? His growth as a character would not only be about his power but also his understanding of this new and complex world.
He would likely disrupt the power balance. His godly powers would be a huge factor. In Highschool DxD, the power system is already complex with devils, angels, and other beings having their own abilities. Naruto being the Son of God would introduce an entirely new level of power that could either intimidate the existing factions or make them try to recruit him.
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.
The female characters from Highschool DxD, like Rias, would be intrigued by the unique personalities of the Naruto characters. Rias might see potential in some of them to join her peerage. And the Naruto girls, like Sakura, would be a bit shocked at first by the more revealing outfits and flirty nature of some of the Highschool DxD characters. But over time, they would bond over things like protecting their friends and the school. The Naruto boys would respect the power of the Highschool DxD devils and might even try to incorporate some of their fighting strategies into their own ninja combat styles.
Well, it could be really interesting. The characters in Highschool DxD might get some new and crazy ideas. For example, Issei might be inspired by the ninja skills in Naruto fanfiction and try to incorporate them into his own fighting style. He could start thinking about using stealth and quick strikes like a ninja in his battles against other devils or fallen angels.
God Ichigo could be a game - changer in a Highschool DxD fanfiction. He might act as a mediator between the different factions. Given his experience with different types of spiritual beings in the Bleach universe, he could bring a new perspective to the ongoing conflicts in DxD. For example, he could try to stop the senseless fighting between the devils and angels, which is a common theme in DxD.
