Naruto becoming Mizukage would change his relationships with the Mist ninjas in multiple ways. The older, more traditional Mist ninjas might initially oppose his more lenient and friendly approach. However, as they witness the positive results, like increased morale among the younger ninjas and better cooperation within the village, they'd come around. The younger ninjas would quickly warm up to Naruto. They'd see him as a cool and powerful leader who's not afraid to get his hands dirty. His relationships would also affect how the Mist ninjas interact with Konoha ninjas, leading to more friendly exchanges.
If Naruto was the Mizukage in fanfiction, the village's attitude towards outsiders would likely change. Naruto has always been about friendship and unity among different villages. So, the Hidden Mist might become more open to alliances and cooperation with other villages. The training methods could also change as Naruto might introduce some of Konoha's training techniques. The village's overall morale would probably improve as Naruto's positive and determined personality would be inspiring to the Mist ninja.
The Hidden Mist Village would see a transformation. Naruto's presence as Mizukage would mean that the village would become more open to outsiders. His reputation for never giving up would inspire the Mist ninjas. In terms of the village's structure, he might reform the way the ninja squads are formed. He'd also encourage the development of new jutsu by promoting a more collaborative environment. And with his influence, the Hidden Mist could become a more prosperous and peaceful village.
Naruto's relationship with his teachers could also change. They would be proud of his growth in intelligence. But at the same time, Naruto might start to question some of their teachings and suggest new ways of doing things. With his peers, he could be a great source of knowledge and advice, which could strengthen some friendships while causing some envy in others. Overall, his relationships would be in a state of flux as he adapts to his new intellectual abilities.
Well, with his friends, Naruto's relationships would change significantly. They would be confused and concerned. Sakura might try to use her medical skills to see if there's something physically wrong with Naruto that's making him act like a mini Madara. Kakashi would be on high alert, not knowing if Naruto could be a threat. Naruto's relationship with the younger generation, like Boruto and the others, would also be affected. They would look at him differently, and Naruto would have to deal with their disappointment and fear. He would have to work hard to regain their trust and show that he's still the Naruto they know deep down.
With Kakashi, it would be a complex situation. Kakashi might have tried to prevent Naruto's banishment but failed. When Naruto becomes Raikage, Kakashi would have to respect his new position. Naruto's relationship with the people of the Land of Lightning would start off as a bit of an outsider but as he becomes Raikage, they would look up to him. His relationship with the other Kage would also change. They would see him as a new player in the political and ninja world. Some might be skeptical of his sudden rise in the Land of Lightning, while others might be interested in forming alliances with him.
His relationship with Kurama might become more complex. Since he's now also a kitsune - like being. They could either become more competitive or find a new way to cooperate. With his friends, some might be in awe of his new form, while others might be a bit scared at first. But Naruto's kind heart would eventually make them all accept him as before.
If Naruto becomes a nukenin, his relationship with the village elders would be completely severed. They would see him as a threat, and he would see them as unjust. With his peers, some might side with him, believing in his innocence. Others would follow the village's orders out of loyalty. His bond with the Nine - Tails would also change. The Nine - Tails might offer more support, seeing Naruto as an outcast like itself.
His relationship with Sasuke would be greatly affected. Sasuke, who has his own experiences with the idea of killing, might see Naruto in a new light. They could either become rivals again or Sasuke might try to 'save' Naruto from his new dark path. With Sakura, she would be horrified. She's always seen Naruto as a positive force, and this change would make her question everything. She might even try to use her medical skills to 'cure' Naruto of his new - found killer tendencies.
If Naruto becomes a Saiyan in fanfiction, his relationship with his mentor, like Jiraiya, could be different. Jiraiya would have to guide Naruto in handling these new Saiyan powers. Naruto's friends might be both in awe and a little scared. For example, Sakura might be worried about Naruto losing control of his new powers. And his relationship with the villagers could change too. Some might see him as an even greater protector, while others might fear his new, more alien - like powers.
His relationship with Sasuke would be very different. Sasuke might see Naruto as even more of an enigma. He could be both jealous of Naruto's new power and also concerned about what Naruto has become. Naruto, on the other hand, would try to show Sasuke that he's still the same person deep down.
