In this kind of fanfiction, Naruto might grow up with a very different set of skills and values. He could be more attuned to the Uchiha's Sharingan - related techniques. Maybe he'd be more brooding like the typical Uchiha, instead of his usual energetic self. Also, his relationship with Sasuke would be really interesting, as they would be more like brothers from the start rather than rivals.
Well, a really interesting plot twist might be that Naruto's upbringing among the Uchiha makes him question his own identity more than in the original story. He might be torn between his Uzumaki heritage and the Uchiha values he was raised with. For example, the Uchiha are known for their pride and a certain sense of isolation in some ways. Naruto, with his usual sunny disposition, could either rebel against these aspects or try to find a new way to incorporate them into his life. This internal conflict could lead to some really intense character development and might even change the way he approaches his relationships with other characters like Sasuke. Maybe he'd understand Sasuke's actions from a different perspective, which could completely shift the dynamic of their relationship.
Naruto's story would be drastically different. He would probably have a different goal in life. Instead of seeking the village's recognition as he originally did, he might be more focused on restoring the Uchiha clan's honor. His friends would also be different. He'd be closer to the remaining Uchiha members and might not form the same bonds with the people like Shikamaru or Choji. His ninja path would be more centered around the Uchiha's secrets and powers.
His fighting style would likely incorporate more fire - based jutsu. Since the Uchiha are known for their fire - style techniques, Naruto would be trained in those from a young age. He might also use Sharingan - like abilities, even if it's not the real Sharingan. For example, he could develop a way to predict his opponents' moves more accurately, similar to how the Sharingan works.
It could be Sasuke's sister, if there was one in the fanfiction world. She might share some of Sasuke's traits but also have her own unique personality that attracts Naruto.
Well, Naruto being raised by the Uchiha Clan would mean a whole different set of relationships. He would grow up with Sasuke as a closer brother - like figure. The Uchiha Clan's traditions would shape his values. For example, their emphasis on family honor and clan loyalty would be instilled in him. And he would probably be a master of fire - style jutsu much earlier, with the clan's expertise in that area.
Naruto's ninja skills would see a major transformation. With the Uchiha Clan's influence, he'd have a greater understanding of the Sharingan's capabilities and how to counter it. His training would focus on using his chakra in a more efficient and deadly way. Instead of his mass - produced shadow clones, he might learn to create clones with more specialized functions, similar to how the Uchiha use their Sharingan - enhanced clones. His physical combat skills would be enhanced with the Uchiha's taijutsu training, which emphasizes speed and accuracy. Also, his ability to sense chakra would be sharpened as the Uchiha Clan has a strong sense of chakra awareness within their own clan members.
The Uchiha might initially be filled with anger. Their trust in Naruto, if it was there before, would be completely shattered. They could start to plot revenge against Naruto, believing that he has wronged them. This could lead to a lot of tense moments in the fanfiction as the Uchiha gather their strength and resources.
One possible plot twist could be that Naruto develops Uchiha - like abilities early on. Since the Uchiha are known for their Sharingan and powerful fire - style jutsu, Naruto might accidentally awaken a form of Sharingan - like power due to being raised in an Uchiha - influenced environment. This could cause a stir in the ninja world as it goes against the normal development of a Jinchuriki.
With Sakura, Naruto might not have the same kind of unrequited love. If he is raised by Uchiha, his values and priorities could be more in line with the Uchiha way of life. He may see Sakura more as a friend or comrade rather than having romantic feelings for her. Also, Sakura might be more intimidated by Naruto if he has Uchiha - like traits.
