In a fanfiction where Naruto is raised in Uzushiogakure, his entire world view would be shaped differently. Uzushiogakure has its own culture and values. He would be influenced by the village's more laid - back and sea - faring nature. His clothing style might be different, perhaps more in tune with Uzushiogakure's aesthetics. And his role models would be different Uzumaki figures rather than the ones in Konoha. This would have a significant impact on his growth as a ninja and as a person.
One possible plot could be that Naruto grows up with a strong connection to the Uzumaki heritage. He might learn unique Uzumaki jutsu from the start. For example, he could master advanced sealing techniques more easily. Also, his personality might be shaped differently. Instead of being an outcast in Konoha, he could be a respected member in Uzushiogakure, growing up with a sense of pride in his clan.
Naruto's power development in Uzushiogakure in fanfiction would be quite different. Since Uzushiogakure was rich in Uzumaki heritage, he'd have more opportunities to explore his own Uzumaki powers. He could learn advanced sealing jutsus at a young age. These jutsus could be used not only for combat but also for things like storing chakra or creating barriers. His physical training might also be different, focusing more on agility and balance, which are useful for a village near the sea. All these factors would contribute to a very different power - up path compared to his growth in Konoha.
His character would likely be more in touch with his Uzumaki roots. He'd be more confident as he wouldn't face the same kind of ostracism he did in Konoha. He might be more outgoing and proud of his heritage.
His relationship with Sasuke would likely be very different. Without the shared experiences in Konoha, their initial rivalry might not be as intense. Naruto might not be as desperate to bring Sasuke back. And his relationships with his other Konoha friends like Sakura and Kakashi would also change. He'd be more connected to Yugito's friends and allies instead.
He'd probably be more cautious. Quarians live in a fragile environment, and Naruto would grow up learning to be careful. So, instead of his usual head - on approach, he might think more before acting.
Naruto could be more empathetic towards the Uchiha's cause. Since Mikoto is his mother figure, he would be exposed to the Uchiha's history and their grievances from a young age. This would make him more understanding of Sasuke's later actions and more likely to try and find a peaceful solution for the Uchiha's problems.
Naruto's story would be different in terms of his upbringing. Instead of the loneliness he faced in the original, with the Yamanaka, he might have a more family - oriented environment. He could be taught the values of the Yamanaka clan from an early age.
He might be more aloof. Since a phoenix is a rather otherworldly creature, Naruto could pick up some of its more detached qualities. He may not be as quick to make friends as in the original story, instead observing more from a distance before approaching others.
Naruto might be more knowledgeable about the history and politics of the village. Hiruzen, being the Hokage, would surely educate Naruto on such matters. This would make Naruto more diplomatic and better able to handle complex village - related issues. He would also be more respectful of traditions and the hierarchy within the village, having been raised by the village's leader.
He might have an enhanced sense of smell and hearing, similar to animals that live in grassy areas. This would give him an advantage in detecting enemies or finding things. For example, he could track someone by the scent they leave on the grass.
