Naruto's character would develop a different sense of loyalty. Instead of being loyal to Konoha, he'd be loyal to Kumo. His goals would change too. Maybe instead of aiming to be Hokage, he'd aim to be one of the top - ranking ninjas in Kumo. His social skills could also be different. Kumo has a different social environment, so he might be more rough around the edges in his interactions.
Naruto's character would likely be more edgy. With Obito's influence, he might be quicker to question the village's motives. He'd also be more powerful in different ways, like having a better understanding of space - time ninjutsu early on.
Naruto's character development in this fanfic would be quite remarkable. Iroh's teachings would shape Naruto into a more centered individual. He would no longer rely solely on his brute strength and the Nine - Tails' power. Instead, he would start to value wisdom and diplomacy. Iroh could teach Naruto how to handle his emotions better, especially his anger and frustration. As a result, Naruto would be a more balanced ninja, able to face challenges with a cool head and make more rational decisions. His relationships with others would also change, as he would approach them with more empathy and understanding, having learned from Iroh's kind and patient nature.
In this kind of fanfic, Naruto's character might develop in a way that he is more attuned to the spiritual side of the ninja world. Since Karma has some sort of otherworldly origin, he could start to see things from a different perspective. He might be more empathetic towards enemies who also have strange powers, as he understands the burden of having something that others don't understand. His growth would be about not only physical and ninja skills but also about his understanding of different forces at play in the world.
Naruto's character could develop a sense of duty towards the Hidden Cloud Village. He would be influenced by the Raikage's leadership, so he might be more disciplined and less of a prankster. Also, he could be more attuned to the politics and power dynamics within the Cloud Village, which would shape his interactions with other ninja villages.
His social skills might be underdeveloped at first. Since he was raised by wolves, he may not understand human social cues and norms easily. He could be more solitary and have trouble making friends in the beginning.
Naruto's character could develop by becoming more understanding of the complex relationships between different villages. Saving Wave from Kumo would make him realize that not all Kumo ninjas are bad, but there are also those with malicious intentions. This would add a layer of maturity to his view of the ninja world.
His personality might be more rough around the edges. Kumo has a tougher environment, so he'd likely be more assertive.
Naruto's development would be a very interesting mix. In Kumo, he'd be exposed to different types of chakra natures and fighting styles. His Rasengan, for instance, could be modified with Kumo's lightning chakra to create a more powerful and unique attack. Minato's influence would ensure that Naruto has a solid foundation in space - time ninjutsu. Also, being in Kumo, Naruto might learn to control his Nine - Tails chakra in a different way, maybe with the help of Kumo's unique methods of chakra control. This would make him an even more formidable ninja compared to his original development in Konoha.
His character may develop a sense of independence. Since he's raised in the wild, he has to rely on himself. He'll be more self - sufficient and less likely to trust others easily at first.
His character might be more hardened. Growing up with Yahiko, he'd be exposed to the harsher side of the ninja world earlier. So he'd be less likely to trust blindly.
