Naruto would likely become more reserved. Since Kisame is not as expressive as some of Naruto's friends in the Leaf Village, Naruto would pick up on that. His fighting style would also change. He'd probably be more stealthy and calculating, learning from Kisame's experience. For example, instead of his usual head - on attacks, he'd start to use more misdirection and ambush tactics.
His view of the world would shift. Growing up with Kisame, he'd see the ninja world as a much harsher place. This would make him more cynical in some ways, but also more determined to find his own path. He might not be as quick to trust others as he was before. However, his core values of friendship and protecting those he cares about would still remain, but they'd be tested in different ways. He'd have to balance his loyalty to Kisame and his new life with his old ties to the Leaf Village.
Naruto's character would likely become more reserved in some ways. With Itachi's influence, he'd think more before acting. But he'd also become stronger and more confident. Kisame's tough training would make him physically tougher. Naruto might also start to question some of the things he learned in the village, as Itachi and Kisame have different perspectives.
Naruto's character might become more calculating. Kisame is a very strategic fighter, and Naruto could pick up on this trait. He would start to think more before acting in battles.
Naruto's character would likely become more reserved at first. Konan's calm and collected nature might rub off on him. But he'd still keep his core of determination. He'd probably learn to be more strategic in combat, taking after Konan's planning skills. His view on the world might also change as he grows up in the Hidden Rain Village instead of Konoha.
Naruto would likely be more confident. Since Hiruzen is a respected figure, Naruto would grow up feeling more secure. He'd probably be less impulsive as he'd have Hiruzen's wisdom to guide him.
Naruto's character could become more in - tune with the spiritual side of things. Since Yugito has a connection to the Nibi, Naruto might start to understand the nature of tailed beasts better. This could make him more empathetic towards them. Also, he could pick up some of Yugito's calm and collected nature, which would be a contrast to his usual boisterous self.
Naruto's character would likely become more adaptable. Living in a different village with different values and traditions would force him to be more flexible. He might also become more stealthy, as the Hidden Mist village has a reputation for its ninja's stealth skills.
Naruto's character would become more hardened. Zabuza's influence would make him less naive. He would be more calculating in battles and less likely to rush in without a plan. His view of the ninja world might also change. He could see the darker side of it more clearly.
Well, Naruto's character would develop in a unique way. He would grow up with a different set of values compared to the original Naruto. Since he is adopted by the Kyuubi, he would have a deeper understanding of power and its responsibilities. He would be more in tune with his inner self, as the Kyuubi would help him explore his chakra and his true nature. He might also be more aloof from the other villagers at first, as he has a special bond with the Kyuubi, but as he grows, he would use his new - found knowledge and power to bridge the gap between them and show them that he is not the outcast they thought he was.
Naruto's character would likely become more complex. He might start off as a more cynical version of himself, influenced by Madara's jaded view of the ninja world. But his natural kindness and will to protect others would still be there, just hidden deeper. As he grows, he would constantly struggle between Madara's teachings and his own inner values.
Naruto's character would likely become more confident. With a family structure provided by Mikoto, he would feel more secure. He might also become more mature as he is exposed to the Uchiha way of life. For example, he could learn discipline and patience more quickly. His understanding of the ninja world would expand as he learns from Mikoto about different clans and their relationships.
