Well, it might be about Naruto having some sort of connection to Jashin. Maybe he discovers he has Jashin's powers. For example, he could have an inner struggle as Naruto is usually associated with positive values and Jashin is often linked to more dark and violent aspects in the Naruto universe.
In this fanfiction, perhaps Naruto's journey as the son of Jashin is about finding a new path for himself. He could try to redefine what it means to be related to Jashin. Instead of following the dark ways usually associated with Jashin, he might use his new powers in a way that is more in line with his own values, like protecting the weak and bringing peace, but still having to deal with the stigma of being Jashin's son.
The plot could revolve around Naruto being the son of Jashin and how that changes his relationships. His friends in Konoha might be shocked and some might even be afraid of him. It could also lead to Naruto having to face enemies who either want to use his new - found heritage or destroy him because of it.
Maybe Naruto, with his godlike powers, meets a female follower of Jashin. They start off as enemies but gradually find common ground and fall in love.
In a 'Naruto raised by Jashin' fanfic, Naruto would likely be an outcast in Konoha from the start. Since Jashin is a rather dark and feared cult - like figure in the Naruto universe. His appearance might be different too, maybe with some markings related to Jashin. His relationships with other characters would be strained. For example, he might not be friends with Sasuke as they have such different upbringings and beliefs. He could be seen as a threat by the village elders and constantly be under surveillance.
A 'naruto married to jashin' fanfiction could be a complex exploration of two different worlds colliding. Naruto represents the values of hope, perseverance, and love in the Naruto universe. Jashin, on the other hand, is associated with death and sacrifice. The story could show how Naruto's positive influence might start to change the way his Jashin - associated partner views the world. It could also delve into the cultural differences between the normal ninja way of life and the extreme practices related to Jashin. There could be many plot twists, like Naruto having to protect his partner from other ninjas who see the Jashin connection as a threat, or his partner having to hide their true nature from the villagers. This kind of fanfiction has the potential to be a very engaging read as it plays with the contrast between light and dark, good and evil within the Naruto universe.
Naruto is the central figure for sure. But we can't forget about the villains in the Naruto universe. Orochimaru might be interested in Naruto's new powers if he is the son of Jashin. He could try to either steal his powers or use Naruto as a tool. And then there are the Akatsuki members. They might see Naruto as a new threat or an opportunity, depending on how his powers as Jashin's son manifest.
Well, perhaps the plot could involve Sakura initially being unaware of her true heritage. She might start to have strange powers or instincts that she doesn't understand. As she discovers her relation to Jashin, she could struggle with whether to embrace this dark side or reject it, all while still being part of Team 7 and trying to protect the Hidden Leaf Village.
Well, first of all, the implications for Naruto's relationships would be massive. His friends like Sasuke, Sakura, and Kakashi would have to reevaluate their relationship with him. They've always known Naruto as a positive force. But if he were connected to Jashin, it would be like a betrayal of sorts. Also, the ninja villages would see Naruto in a completely different light. They might view him as a threat rather than a hero. And in terms of the story's overall theme of hope and perseverance, it would be turned on its head. Instead of a story about a boy rising above his hardships through positive means, it would become a much more complex and potentially disturbing tale of a character with a dark and conflicting nature.
In a 'naruto son of bellatrix fanfiction', perhaps Naruto has some of Bellatrix's wild and unpredictable nature. He could be on a journey to discover his true identity and how he came to be Bellatrix's son. This might lead him to explore the secrets of the wizarding world and his own ninja abilities in a new light.
Well, one possibility could be that Naruto inherits some of Gilgamesh's arrogance along with his power. Maybe he has a special ability to summon ancient Babylonian weapons. And he could use this in his battles in the Naruto world, like against the Akatsuki.
One possible plot could be that Naruto discovers his true heritage as the son of a princess from a hidden kingdom. He then has to deal with the politics and expectations of the royal family while still maintaining his ninja ways. Maybe he has to protect the kingdom from a new threat using his ninja skills.
In such a fanfiction, perhaps Naruto could be shunned by the village from the start. His 'devil' heritage might give him strange powers that he has to hide. He could struggle with self - identity, different from the Naruto in the original who is seen as a hero. Maybe he has to fight against the prejudice of the people who believe the devil's son can only bring destruction.
