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.
In this fanfiction, Naruto's character development would be quite different. Growing up under the Kyuubi's care, Naruto would have access to a wealth of knowledge and power. This would make him more self - assured. He would no longer have the same insecurities as the Naruto in the original series. His relationship with his peers would be different too. Instead of constantly trying to prove himself, he would already know his worth. His ninja skills would develop at a faster rate, as he has the Kyuubi to guide him. And his understanding of the world would be broader, as the Kyuubi could tell him stories and secrets about the shinobi world that no one else knew. This would all contribute to a Naruto who is more of a leader and less of a troublemaker, yet still retains his kind heart and determination to protect those he cares about.
Naruto's character would develop in a more complex way. He would be influenced by Kyuubi's wisdom and power. Kyuubi could teach Naruto about the true nature of power and how to use it responsibly. This would make Naruto more mature at a younger age. He might also be more introverted as he would be spending a lot of time with Kyuubi, learning from it. But at the same time, he would still have that underlying kindness and determination that is characteristic of him. He would just have a different way of expressing it and using it to achieve his goals.
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.
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.
Naruto would likely become more calm and calculating. Shisui's influence would make him think before acting. For example, instead of rushing into battles head - first, he'd assess the situation first.
Naruto's character would likely become more emotionally stable. With Kurenai as a mother figure, he'd have someone to confide in. He might be less impulsive as he grows up, since Kurenai would teach him to think before acting. His ninja skills could also be different. He might be more proficient in genjutsu due to Kurenai's influence. Overall, he'd have a more positive self - image, knowing he has a family who loves and supports him.
