The relationship would have a major impact on Naruto's character development. Knowing he has an Uchiha brother, he might study more about the Uchiha ways and culture. This could lead to new jutsu combinations, like combining his Rasengan with some Uchiha - style fire jutsu. Emotionally, it would give him a stronger family bond, which was something he always desired. In the overall Naruto universe, this could inspire other characters to look beyond clan differences and strive for unity, as Naruto and Shisui's relationship would be a symbol of bridging gaps between different groups.
If Naruto and Kurumu are siblings, it could have a big impact on Naruto's character development. He might become more protective of Kurumu, which could lead to him making different decisions in battles or in his interactions with other characters. Also, Kurumu could introduce new ideas and ways of thinking to Naruto that are different from what he learned in the ninja academy. This could change how he approaches problems and how he views the world around him. For instance, if Kurumu has a more diplomatic way of handling things, Naruto might start to use more negotiation rather than just brute force in some situations.
Their relationship could change the perception of the Uzumaki and Uchiha clans. Traditionally, the two clans haven't had much interaction in the original story. But as brothers, Naruto and Shisui could bridge that gap. This might lead to new alliances and political changes within the Hidden Leaf Village.
If Naruto eats the Shinju, it could greatly disrupt the balance of power in the Naruto universe. His newfound power might make him a target for those who seek to control or destroy such power.
If they were siblings, it could change the way Naruto interacts with the Uzumaki clan. He might have a stronger connection to his heritage through Karin, and this could lead to new alliances. For example, he could gain more support from Karin's friends or former associates.
It could make Kakashi more protective of Naruto. Since Kakashi is well - aware of the power of Shisui's eyes, he would know the potential danger Naruto is in. He might train Naruto more intensively to help him control the eyes and also protect him from those who would seek to take the eyes for themselves.
Well, their relationship could bring a new dynamic to the village. People in Konoha would see their relationship as a sign of change. It might inspire more female ninjas to be more open about their relationships and not be held back by traditional ninja values.
On the other hand, this could also be a chance for Naruto and Kakashi to have a more open conversation. Naruto could share his thoughts on how the fanfiction is misinterpreting Kakashi, and Kakashi could use this as an opportunity to understand Naruto's perspective better. This could potentially strengthen their relationship as they gain a deeper understanding of each other's views on how Kakashi is perceived in different fictional scenarios.
If Naruto is Bella's brother in this fanfiction, it could completely rewrite the Twilight saga. His upbringing in the Hidden Leaf Village would give him a different perspective. He might introduce some of the ninja concepts like chakra to the Twilight world. His relationship with Bella would also mean that he'd be involved in her love story with Edward, perhaps trying to understand Edward's motives more deeply or even challenging him to prove his love for Bella.
Yes, there might be such fanfics in the Naruto fanfic community. Some fans like to create unique family relationships in their stories, and making Naruto and Shisui brothers is an interesting concept that could lead to many different plotlines and character interactions.
It could change the dynamics between the characters. For example, if Naruto's secret boyfriend was Sasuke, it would add a whole new layer to their already complex relationship. The reactions of other characters like Sakura would be very different. She might feel betrayed or confused.
