He would likely have the Sharingan. This would give him the ability to copy jutsu just by seeing them, and also predict his opponents' moves. His combat skills would be enhanced as he could use the Sharingan's powers during battles.
If Naruto was born in the Uchiha clan in a fanfic, his abilities would be a blend of his original Uzumaki powers and Uchiha abilities. He might have stronger chakra control due to the Uchiha's training methods. The Sharingan could also unlock new forms of his Rasengan, perhaps a more powerful and visually distinct version. And his ability to sense danger and react quickly would be boosted by the Sharingan's perception - enhancing capabilities.
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.
The story would take a whole new turn. Naruto's appearance would be different, probably having the distinct Uchiha features. His social standing in the village would change. He'd be part of one of the most powerful and feared clans. This would also affect how others perceive him. His friends might be more from the Uchiha clan initially. His training would involve learning about the Uchiha's history and their secret techniques. The plot would likely revolve more around Uchiha - related issues, like the Curse of Hatred that plagues the clan. And his role in the village's future might be more intertwined with the Uchiha's fate.
He would probably have strong chakra reserves like the Senju. And he might be able to master wood - style jutsu more easily. His physical strength could also be enhanced due to the Senju's natural traits.
Well, in such a fanfic, Naruto might have the Sharingan from birth. He could be trained in Uchiha - style jutsu right from the start. His personality might be influenced by the Uchiha clan's pride and determination. Also, his relationships with other characters like Sasuke would be very different, as they would be clan - mates instead of rivals in the traditional sense.
His sense of smell would likely improve significantly. Since the Inuzuka clan has a strong connection with their ninja dogs and are known for their enhanced sense of smell, Naruto would be trained in this area. This could help him in tracking enemies or finding hidden objects much more easily than in the original story.
If Naruto was born in the Uchiha clan in fanfiction, he would surely have the Sharingan. This powerful eye technique would give him enhanced perception, allowing him to copy other ninja's moves more easily. He could also use Genjutsu more effectively. Along with that, he might still have some connection to the Nine - Tails, but it could be more subdued or combined with his Uchiha powers in a unique way. Maybe he could use the Nine - Tails' chakra to boost his Sharingan abilities, like increasing the power of his Amaterasu if he were to unlock it.
The relationships in the story would be different. In the original, Naruto had a complex relationship with Sasuke, who was an Uchiha. But if she was an Uchiha herself, that dynamic would be completely altered. They could be more like siblings or rivals within the clan. Also, her relationship with Kakashi would be different as he had his own history with the Uchiha.
If Naruto was adopted by the Uchiha clan in fanfiction, his life would be transformed. He'd be exposed to the Uchiha's traditions and history. His appearance might even change as he adopts some Uchiha traits. His social standing in the village would improve, and he'd be more respected. He could also be mentored by Uchiha elders, which would enhance his ninja skills.
The Uchiha clan's perspective would vary from member to member. Those who are more adaptable might embrace the fanfiction as a new form of entertainment. They could enjoy seeing their clan's characters in different relationships and adventures. However, the more conservative members would likely resist any change to their perceived image and might reject the fanfiction entirely.
His training would change. He'd likely focus more on swordsmanship and the Hatake clan's specific jutsu. Maybe he'd be taught by the clan elders instead of the usual Leaf Village instructors.
