His relationships would be very different. He might not have the same bond with Sasuke and Sakura. Instead, he could form closer relationships with the older generation of ninja. For example, he might be friends with Kakashi when Kakashi was still a young and up - and - coming ninja. His relationship with the Hokage at that time would also be different. He could be seen as more of a protege to them rather than the young outcast he was in the original story.
Naruto's relationships would change significantly. He would have the opportunity to interact with the older characters in a different way. For instance, he could have a closer relationship with Minato's friends, like Jiraiya. Since he'd be born 10 years earlier, Jiraiya might take on a more father - like role in Naruto's life much sooner. His relationship with the other Jinchuriki might also be different. In the original story, he met them later, but in this fanfiction, he could encounter them earlier and form different alliances or rivalries. And his relationship with the village as a whole would be redefined, as his early presence would bring new dynamics to how the village perceives and treats him.
If Naruto was born 5 years earlier, the entire timeline of the story would be disrupted. For one, he would be graduating from the Academy earlier and joining teams earlier. This could mean that he'd face stronger opponents at a younger age, which might either make him stronger faster or get him seriously injured. Also, his relationships with characters like Sasuke and Sakura would develop differently. Maybe Sasuke wouldn't see him as such a rival since Naruto would be ahead in terms of ninja development.
In this fanfiction scenario, Naruto being born 10 years earlier could have a huge impact on the story. For one, he'd be part of an earlier generation of ninja. He might have different relationships with the older characters. Maybe he'd train under different mentors, like perhaps he could have learned from the Third Hokage at a much younger age. This could lead to him developing different skills and a different combat style. Also, his presence in the ninja world so much earlier could change the political landscape as well, since his status as a Jinchuriki would be a factor much sooner.
One consequence could be that Naruto would be more isolated in his early years. Since he'd be younger than most of his peers, they might not understand him as well. Also, the power dynamics in Konoha would shift. With Naruto developing his skills earlier, other ninja clans might feel threatened or more competitive. Another consequence is that Naruto's relationship with his father figure, Iruka, might not be as strong. Iruka might not have been his teacher in the same way if Naruto was born earlier.
His relationship with Sasuke would likely be affected. Sasuke might be both intrigued and wary of Naruto's hollow abilities. They could have new reasons for rivalry, like Sasuke wanting to prove he's stronger despite Naruto's unique powers. Or, they could end up teaming up earlier to figure out what Naruto's hollow nature means.
If Naruto were born an Uchiha, his relationship with Sakura might be affected. Sakura might be more drawn to him initially because of the allure of the Uchiha clan. However, Naruto might be more focused on restoring the Uchiha name and proving that they are not all bad. His relationship with the villagers would be complex. Some would be fearful, while others might hope that he could use his Uchiha powers for the good of the village.
In a 'naruto born earlier fanfiction', one possible scenario could be that he might grow up in a different political climate in the Hidden Leaf Village. Maybe he would have different relationships with the older generation. For example, he could form a closer bond with the Third Hokage at an earlier age and learn more about the village's secrets earlier on.
He might be more mature earlier. Since he would have more time to experience life in the village, he could be less impulsive. For instance, he might not pull as many pranks as in the original story.
His relationship with Sasuke would likely be different. With Naruto being a sage from birth, Sasuke might see him as an even greater rival or, perhaps, someone to look up to more. Naruto could use his sage - like wisdom to better understand Sasuke's pain and motives, and might be more effective in bringing Sasuke back to the village earlier.
With Iruka, I think Iruka would be very protective. He already cares about Naruto, and the wings would just make him more concerned for Naruto's well - being. As for Sakura, she might be a bit shocked at first but then would see it as just another part of Naruto and continue to have her normal feelings for him. With Kakashi, he would probably be very interested in how Naruto could use the wings in combat and training.
His relationship with Sasuke would likely become more of a partnership. As Hokage, Naruto would need Sasuke's skills and knowledge to protect the village. They would probably have regular meetings to discuss security and other important matters.
