For one, Naruto's relationship with Sakura would change. Sakura has always been infatuated with Sasuke, but if Naruto is the heir of the Uchiha clan, she might start to see Naruto in a new light. Also, Naruto's bond with the village elders would be altered. They would either be more protective of him as the heir of a powerful clan or be more suspicious of his new - found status. And his connection with other Uchiha survivors, if any, would be that of a leader or a symbol of hope for the clan's revival.
His relationship with Sasuke would be completely different. Instead of being rivals, they could become brothers. They would train together, share secrets, and support each other in a way that they couldn't in the original story. Naruto would also have a closer bond with Itachi, who might see Naruto as a new hope for the clan and mentor him.
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.
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.
His status would change significantly. He would be seen in a different light by the villagers. Instead of being just an orphan with the Nine - Tails, he'd be a part of one of the most important clans in the village. People might respect him more and expect greater things from him.
His relationship with Sasuke would be different. Without the shared experience of being outcasts in the village, they might not have the same initial bond. Naruto would have a stronger support system from his Uzumaki family, so he might not be as desperate for Sasuke's friendship in the same way.
Well, it would definitely strain Naruto's relationship with Sasuke. Since Sasuke is an Uchiha, Naruto's hatred towards the clan would put a huge rift between them. They might not be able to have the same kind of bond as in the original story.
His relationship with Sasuke could become more complex. Since Sasuke is an Uchiha, Naruto learning Uchiha clan secrets might make Sasuke feel a mix of emotions. He could be jealous that Naruto has access to something that was meant for the Uchiha, or he could be glad that Naruto is now more in - tune with his own past as an orphan with a powerful lineage.
His relationship with Sasuke would be completely shattered. Sasuke, as an Uchiha, would surely seek revenge against Naruto. This would create a very intense and dark dynamic between them, far from their original friendship.
Well, if Naruto was born into the Uchiha clan in a fanfiction. His entire backstory would be rewritten. For one, he'd be part of a clan that had a tragic history even before the events of the main Naruto story. He would have access to the Uchiha library and knowledge, which could make him a much more knowledgeable ninja at a younger age. In terms of his fighting style, he'd probably incorporate more Uchiha - style jutsu. His relationship with Kakashi would be different. Since Kakashi had a connection to the Uchiha through Obito, there could be a more complex dynamic. Also, Naruto's role in the Uchiha massacre plot could be completely different. Maybe he could even prevent it, given his different perspective and abilities.
His relationship with Sasuke would be different. Instead of the rivalry born out of their time in Konoha, it could be more of a friendly competition between two powerful clans. Naruto, being Uzumaki - raised, would have a different perspective on power and friendship.
