Dark Naruto in a High School DxD fanfiction would be a complex character. He would carry the trauma and power-hungry tendencies from his Naruto backstory. In the DxD world, this could manifest as a drive to become stronger, not just physically but also in terms of influence. He might be initially distrusted due to his dark nature, but his loyalty and determination could win over some of the characters. He could be a wildcard, not fully aligning with the devils, angels, or the other factions, and always looking out for his own interests while also having a sense of justice that is unique to him.
The character could be a catalyst for change. The EMS gives them access to powerful abilities. In the High School DxD world, which is often about power struggles and hierarchies, their presence could disrupt the status quo. They might inspire other characters to strive for greater power or to question the existing power structures. For example, if they use their EMS to defeat a powerful devil who has been oppressing others, it could start a movement among the weaker characters to stand up for themselves.
He would still likely have his chakra - based powers from the Naruto universe. So he could use techniques like the Rasengan or Shadow Clone Jutsu. However, due to his emotionless state, he might use them in a more precise and less flashy way. His Nine - Tails chakra could also be present, but perhaps he would have better control over it since emotions often cloud his control in the original series.
Evil Naruto would still have his basic ninja powers. He'd have his shadow clones which could be used for various purposes, like spying or overwhelming opponents in battle. His Rasengan would also be a very powerful attack. Additionally, he could have some dark - themed powers due to his evil nature. Maybe he could corrupt his chakra to have a more sinister effect on his enemies, like causing them to feel despair or weakening their will.
A 'Naruto in High School DxD' fanfiction could involve Naruto being transferred to the DxD school. He would stand out immediately with his orange jumpsuit. His Rasengan could be a very powerful move against the devils and angels in that universe. And his sense of justice would likely lead him to get involved in all the power struggles and protect the weak, just like he did in his own world.
Well, in a Naruto and High School DxD crossover with the Dark Excalibur, it could be a really wild story. Maybe Naruto somehow gets transported to the world of High School DxD and discovers the power of the Dark Excalibur. He could use his ninja skills along with the new power of the sword to fight against the devils and other supernatural beings in that world.
Well, a possible story could be about Naruto ending up in the world of High School DxD. Maybe he could use his ninja skills in the battles there. For example, his shadow clone jutsu could be a really unique ability in the world of High School DxD where they mostly deal with magic and devil powers. And as a 'dark knight' in this fanfiction, he might have a darker, more brooding personality, perhaps influenced by the more mature themes in High School DxD.
Well, his powers could be adjusted to fit the High School DxD universe's rules. Maybe his shadow clones could be used in a more sneaky way, like spying on the devils or angels. And his Rasengan might have some new effects, like being able to disrupt the magic in that world.
He could introduce new combat styles. His speed and agility from being a ninja would be a huge advantage. The characters in High School DxD might be very intrigued by his ability to move so quickly and perform complex jutsus.
In a Naruto and High School DxD fanfiction, there could be a scenario where the protagonists of both stories meet in a neutral dimension. Issei from High School DxD might be intrigued by Naruto's ninja skills and determination. Naruto, in turn, could be curious about Issei's Sacred Gear. They could start training together, sharing their knowledge and skills, and ultimately have to face a common enemy that threatens both their worlds.
A 'Naruto is God' High School DxD fanfiction would be full of interesting crossovers. Naruto's sage mode could have a different interpretation in the High School DxD world. He might use it to sense the auras of different supernatural beings more clearly. His relationship with the female characters in High School DxD could also be an interesting aspect. Maybe some of them would be in awe of his god - like status, while others might challenge him. And his moral code, which is influenced by his experiences in the Naruto world, would likely clash or blend with the values of the High School DxD world. This could lead to many complex and engaging storylines as he tries to navigate this new universe while being a god - like figure.
