Their relationship might be a source of great change in the Naruto universe. At the same age, Naruto's influence could have made Itachi question his loyalty to the Leaf Village in a different way. Maybe Itachi would have been more open to Naruto's ideas of peace and unity. And Naruto, having Itachi as a peer, would have had a different perspective on the Uchiha clan. They could form a bond that changes the fate of not only themselves but also the entire shinobi world. For example, they might work together to prevent the Uchiha massacre, which would completely rewrite the story's trajectory.
Well, their relationship could be one of mutual respect. Since they are of the same age, they could be competing on a more equal footing. Itachi's skills with the Sharingan would be pitted against Naruto's growing power of the Nine - Tails. However, Naruto's optimistic view of life might gradually chip away at Itachi's shell of secrecy and guilt. They could end up as comrades, with Itachi perhaps guiding Naruto in some aspects of combat and Naruto showing Itachi that there is a way to break free from the chains of his past actions.
If Naruto was the same age as Itachi, their relationship could be complex. They might start as rivals, both being extremely talented in their own ways. Naruto's boisterous and determined nature could contrast with Itachi's more reserved and burdened self. Itachi might see in Naruto a different path for the Uchiha, one that doesn't involve the darkness he has known. Naruto, on the other hand, would probably be in awe of Itachi's power and at the same time try to understand his seemingly cold exterior.
Their relationship would likely become more of a friendly rivalry. Since they are the same age, they would constantly be comparing their progress in ninjutsu and other skills. Naruto would probably be more eager to prove himself against Itachi, and Itachi might see Naruto as an interesting opponent.
Their relationship with Sasuke would be very different. Naruto might not look up to Itachi as much as in the original story, and Itachi might not see Naruto as a potential threat to Sasuke's growth. Instead, they could both be like older brothers to Sasuke, guiding him in different ways.
The story would be transformed in many ways. Naruto, being as old as Itachi, would have had different training experiences. He might have been trained by different people or in different ways. This would lead to different jutsu and abilities. In the political arena, Naruto could have played a more active role in preventing the Uchiha - Leaf Village rift. His relationship with characters like Kakashi and Jiraiya would also be different. For instance, he might have been more of an equal to Kakashi, and Jiraiya might have had different expectations of him. All these changes would create a whole new narrative for the Naruto story.
If Naruto was born the same age as Itachi in fanfiction, it would change the power balance in the village. Naruto could be part of the decision - making processes earlier. His influence on the Uchiha clan's fate might be significant. He could use his unique ability to persuade and his strong will to try and bridge the gap between the Uchiha and the village. Also, his interactions with Kakashi would be different. Instead of Kakashi being an older, more experienced mentor, they could be more like comrades or even rivals in some aspects.
One interesting plot twist could be that since they are the same age, they become rivals not just in power but also in terms of winning the affection of their peers. Naruto, with his boisterous and friendly nature, and Itachi, with his cool and mysterious aura, both vying for the same friends. Another could be that they end up in the same ninja team, which is unheard of in the original story. This would force them to work together and learn from each other's strengths, like Naruto teaching Itachi about the power of friendship and Itachi teaching Naruto more refined ninjutsu techniques.
If Naruto was Itachi's twin brother in this fanfiction, Sasuke's relationship with both of them would be extremely complex. Naruto would be Sasuke's family in a different way than just a friend. He might be more protective of Sasuke from the start. And Sasuke would view Naruto not just as a rival to surpass but also as part of his family's mystery. Since Itachi was Sasuke's brother, Naruto being Itachi's twin would put Naruto in a strange position in Sasuke's eyes, perhaps a mix of suspicion and a longing for family connection.
They could be friends. They would grow up sharing their dreams and goals. Maybe they'd train together and push each other to be better ninjas.
In many Naruto fanfictions, the ages of Naruto and Itachi can be quite flexible. Sometimes, authors might change their ages to create different story dynamics. For example, an author could make Itachi younger to explore a different version of his character development, perhaps showing him still in the early stages of his ninja training while dealing with the dark secrets of the Uchiha clan. Naruto's age might also be adjusted, like making him older to be in a more equal power dynamic with Itachi from the start.
Their relationship could start as simple acquaintances in the village. As they are the same age, they might be in the same training groups. Slowly, they could develop a mutual respect for each other's skills. Naruto might be impressed by Yugao's stealth abilities, and Yugao could admire Naruto's never - give - up attitude. This could lead to a friendship where they support each other during tough missions and training.
At first, they might be just classmates or friends who notice each other's unique abilities. Naruto would be drawn to Hana's calmness around animals, and Hana would be intrigued by Naruto's never - give - up attitude. As time goes on, they could become closer friends, relying on each other for support during difficult missions or training.
