Well, first of all, the whole concept of power levels would be thrown off. In Highschool DxD, characters are constantly striving to get stronger. Superman already starts off at a very high power level. So, storylines that involve characters training to become stronger might not be as relevant. Also, Superman's origin story is very different from the characters in Highschool DxD. His arrival in this fanfiction world could introduce new themes like acceptance of differences. He comes from a different planet, and his values could clash or merge with the values of the characters in Highschool DxD, which would change the overall direction of the story.
If Superman were in Highschool DxD fanfiction, the power dynamics would be drastically altered. Superman's super strength, speed, and heat vision would make him an overpowered character. He could easily defeat most of the foes in the Highschool DxD universe. This would likely change the plot as many of the story arcs in Highschool DxD revolve around the characters gradually growing in power and facing challenges that match their strength. It might also lead to different character interactions. For example, Superman's moral code might influence the more morally ambiguous characters in the series.
Well, if Mokuton Naruto were in Highschool DxD, it could be really interesting. Maybe Naruto's mokuton abilities would give him an edge in the battles that often occur in the Highschool DxD world. He could use his wood - style jutsu to create barriers or even to attack the devils and other supernatural beings. And his ninja skills like stealth and quick reflexes would also be very useful.
The presence of Ghost Rider in a Highschool DxD fanfiction would likely create a lot of chaos. His powers are far beyond what most characters in Highschool DxD are used to. He could easily become a major disruptor of the power balance. For example, his Penance Stare would be a huge threat to the devils and other supernatural beings in the Highschool DxD universe. His hellfire could also cause massive destruction. However, it could also lead to some interesting alliances. Maybe some of the good - natured characters in Highschool DxD would see him as an ally against the more malicious forces.
If God Ichigo were in Highschool DxD fanfiction, the storyline could be affected in numerous ways. For one, Ichigo's combat skills would likely make him a powerful force in the DxD universe. His Zanpakuto abilities could give him an edge in battles against the devils, angels, and fallen angels in the series. He might also bring a different moral code, as he has his own sense of justice from his experiences in the Bleach universe. This could lead to interesting interactions with the characters in Highschool DxD, who have their own complex moral and power hierarchies.
Well, if Naruto had the Rinnegan in the Highschool DxD world, the power dynamics would change drastically. Naruto's abilities with the Rinnegan could make him a dominant force in the battles against the devils and other supernatural beings. He might introduce new jutsu styles that could shock everyone in the DxD universe. Maybe he'd use his Rinnegan to quickly analyze the powers of his opponents and come up with strategies on the fly.
Well, if Superman were in High School DxD fanfiction, the power dynamics would be completely shifted. Superman's super strength, flight, and heat vision would make him a dominant force. He might be seen as a rival to the devils and angels in the DxD universe. His moral code would also likely influence the more hedonistic characters in the series.
The story could start with Naruto arriving in the Highschool DxD world with his godlike powers. At first, he might try to fit in, but as he discovers the underlying politics and power struggles, he feels the need to change things. His betrayal could be when he opposes the main factions. For instance, if he stops a planned battle between the devils and angels because he believes there's a better way to resolve their differences.
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.
Well, one way the storyline could develop is that the Naruto Godlike Kitsune would bring in his ninja skills to the world of Highschool DxD. He could use his transformation abilities like the Kitsune form to deceive enemies or charm the characters in the DxD world. Maybe he'd form an alliance with some of the main characters to fight against common foes, like the devils or fallen angels who might see his power as a threat.
If Fem Harry was in Highschool DxD, the story would change in many ways. For one, the dynamic with the male characters would be different. Instead of the typical male - male friendships and rivalries, there could be more romantic or complex relationships. Also, Fem Harry might approach the challenges in the DxD world differently. Maybe she'd use her wits in a more feminine way. For example, instead of brute force, she could use her charm to get out of tough situations.
In terms of the overall story, Naruto would add a new layer of mystery and excitement. His backstory as a ninja from another world would be fascinating to the other characters. His training methods and the way he views strength could also influence the characters in Highschool DxD. They might start to adopt some of his ways of thinking, like believing in hard work and perseverance to become stronger.
