In a Naruto, Ghost Rider, High School DxD fanfiction, a great storyline could be that the High School DxD world is in danger of being destroyed by an ancient evil. Naruto and Ghost Rider are brought in as the last hope. Naruto uses his friendship - building skills to gather allies among the students and factions, while Ghost Rider uses his power to fight off the minions of the ancient evil. As they progress, they discover that there are secrets in this world related to their own powers, and they must unlock them to save the day.
Perhaps the story could revolve around a conflict between the Ghost Rider's sense of justice and the more complex moral and power dynamics in the High School DxD universe. For example, he might not agree with how the devils in the school operate, and this could lead to a series of confrontations and alliances as he tries to find his place within the school while still adhering to his own code.
It could be a powerful devil who sees the Ghost Rider as a threat to his plans in the school. Maybe this devil wants to take over the school or gain more power among the students, and the Ghost Rider's presence and his sense of justice stand in the way.
In a High School DxD fanfiction with Naruto and Ghost Rider, their powers could interact in various ways. Naruto's Rasengan, for example, could be combined with Ghost Rider's chain attacks. Naruto's ability to sense danger through his chakra might also be enhanced by Ghost Rider's supernatural senses. They would both be out of place in the High School DxD setting at first, but their powers would quickly make them forces to be reckoned with.
Well, there could be a story where Naruto, after learning about Thor, dreams of becoming as powerful as him. He goes on a quest to find artifacts or powers that are similar to Thor's. Along the way, he meets other characters from both the Naruto and Marvel universes who either help or hinder his journey. This could lead to many interesting interactions and battles, as Naruto tries to prove himself worthy of being like Thor in his own way.
There could be a storyline where Naruto is summoned to the High School DxD world by some ancient magic. He is seen as a powerful ally or a threat depending on who you ask. Rias takes it upon herself to figure out Naruto's intentions. As she gets to know him, she realizes that his values of friendship and protecting the weak are similar to her own. Together, they start a journey to stop a dark force that is rising in the DxD world, with Naruto teaching the devils some ninja techniques along the way.
One possible storyline could be that Naruto, with his unique skills and positive attitude, enrolls in the high school from High School DxD. He might form an unlikely friendship with some of the characters there, like Issei. Together, they could face off against common enemies, with Naruto teaching Issei some of his ninja techniques, adding a new dimension to the battles in the High School DxD universe.
In this fanfiction, a great storyline could be that Naruto and Joramun are seen as prophets or saviors by a small group of people in Westeros who are tired of the constant war and power struggles. They try to spread their message of peace and cooperation, but are opposed by the major houses who see them as a threat to their power. As they journey through Westeros, they also discover secrets about the land that could change everything. Maybe there are ancient powers that Naruto's chakra can interact with, and Joramun has some knowledge about these from his own world. This would create a complex and exciting story full of twists and turns.
One way could be through the power system. The EMS (Eternal Mangekyou Sharingan) from Naruto could be a unique power that a character in the High School DxD world acquires. Maybe a transfer student from a hidden ninja village arrives at the high school and has to keep their EMS a secret while dealing with the devils and angels in the school. This could lead to some interesting battles and interactions as the powers of the EMS, like the ability to use powerful jutsus, contrast with the magic and abilities of the High School DxD characters.
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 possible plot could be that Naruto is somehow transported to the world of High School DxD. He's seen as a delinquent because he doesn't follow the school's rules which are very different from what he's used to in Konoha. He might start fights with some of the devils or fallen angels in the school who underestimate him. As the story progresses, he forms alliances with some of the students and they work together to solve problems in the school, like stopping a powerful enemy that threatens both the human and supernatural students.
