The consequences of Naruto being born 5 years earlier are numerous. In terms of his training, he might have received different training methods. Since the ninja academy might not be fully equipped to handle such a young and talented student, he could have been sent for special training elsewhere. This would change his relationship with the academy teachers and his peers. Socially, he might not have fit in as well with the kids his age, as his interests and abilities would be far more advanced. Politically, Konoha might have used him differently. Instead of hiding his identity as the Kyuubi's jinchuriki at first, they might have revealed it earlier to gain an advantage in the ninja world, which would have had a huge impact on Naruto's life and how he was treated.
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.
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.
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.
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.
One possibility is that it would change his physical abilities in combat. The wings could allow him to have greater mobility, like quickly evading attacks or launching surprise aerial assaults. It might also make him a target, as his unique feature would draw attention from both allies and enemies who might be curious or jealous.
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.
The fanfiction might explore how Naruto's friends and allies react to this betrayal. They could be divided in their opinions. Some might believe Naruto and side with him, while others might be more hesitant, thinking that there must be some misunderstanding. This could create internal conflict within the group. Also, Naruto might be driven to seek revenge, which could set off a whole new chain of events in the fanfiction, like battles or new alliances formed against Wonder Woman.
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.
One possible plotline could be that Naruto's wings make him an outcast in the village at first. People are scared or jealous of his unique feature. But as he grows, he learns to use his wings in combat, perhaps in a new style of ninja fighting that combines aerial maneuvers. He could also use his wings to reach places quickly during missions, giving him an edge.
The story might start with Naruto being born in a small village in Earthland. Since he's used to being an outcast in his original world, he could quickly adapt to any discrimination he faces in Earthland. He could discover he has some sort of latent magic ability along with his chakra. His rasengan could be seen as a super - powerful magic spell in Earthland.
Naruto could try to change Konoha from the outside. He might form an alliance with other villages or groups who share his views on how a village should be run, and then use their combined influence to force Konoha to make changes.
