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.
In this kind of fanfiction, Naruto's life would be drastically different. He might be trained in Kumo's unique ninja arts. Minato being alive could mean he has some sort of connection or influence on Naruto from afar. Maybe Naruto would grow up with a different set of values influenced by Kumo's culture, while still having his father's legacy in the back of his mind.
Naruto's character would develop in a more balanced way. Minato was calm and intelligent. So Naruto would learn those traits from him. He wouldn't have the same insecurities as in the original story. He might be more of a natural leader from the start, as Minato was also a respected leader. And he would have a better understanding of the village's politics and history because Minato would be there to educate him.
His chakra control would likely be extraordinary. Kyuubi is a huge source of chakra, so Naruto would have had early exposure to vast amounts of it. This could lead to him being able to perform more advanced jutsu at a younger age.
His character might become more hardened. Kumo is known for its tough ninjas, and living there would expose Naruto to a more cut - throat environment. He may lose some of his naivete and become more calculating in his actions.
His character could become more adaptable. In Kumo, he'd be exposed to different values and ways of life. This would make him more open - minded. For instance, he might start to view the concept of power in a new light, as Kumo has a different emphasis on strength compared to Konoha.
His physical strength might increase. Dwarves are often depicted as strong, and living among them could mean Naruto has to do a lot of physically demanding tasks like mining or lifting heavy objects. So, he'd likely have more brute force.
His abilities would likely become more brutal. The Espada are known for their raw power and direct combat styles. Naruto might not develop his signature jutsu like the Rasengan in the same way. Instead, he could focus more on melee combat and dark - based energy attacks similar to what the Espada use.
He might gain the ability to transform like Saiyans do. This could give him different power levels and appearances during battles, making him a more versatile fighter.
His abilities would likely become more focused on close - range combat and self - preservation. Hidan is good at getting up close and personal in a fight, so Naruto might develop similar skills. Also, he could learn some of Hidan's unique techniques related to his immortality, although it's not clear if Naruto could fully replicate them. But overall, his combat style would be less about flashy long - range attacks and more about brute force and survival.
Naruto's combat style would be more refined. Sakumo was a highly skilled ninja, and he would teach Naruto better swordsmanship skills perhaps. Naruto's taijutsu could also be more precise and calculated. Also, Naruto might develop better chakra control earlier, as Sakumo could instill in him the importance of efficient chakra usage from a young age.
