His relationships would be completely turned upside down. His friends in the Leaf Village would be confused and hurt. Meanwhile, in Akatsuki, he'd have to build new relationships. Some members might be hostile at first, but others could potentially become comrades. For example, he might form an unlikely bond with Hidan, who is very different from Naruto in beliefs but they could learn from each other in a strange way.
In the fanfiction where Naruto is banished and joins Akatsuki, his relationships would experience a seismic shift. His bond with Kakashi and the other Leaf ninja would be strained to the limit. They might think he has turned to the dark side. Inside Akatsuki, he'd be in a world full of anti - heroes and villains. His relationship with Pain would be crucial. Pain, who has his own view of the ninja world order, would either see Naruto as a tool or a potential disruptor of his plans. Naruto would also have to deal with the fact that some Akatsuki members might try to manipulate him because of his naivete in some aspects, while he tries to understand their motives and change them for the better.
If Naruto joined the Akatsuki, his relationship with the other Akatsuki members would be diverse. Some, like Hidan, might see him as an enemy no matter what. But others, like Konan, might be more open to him. She has a more complex view of things compared to some of the more blood - thirsty members. Naruto would also have to deal with the Akatsuki's leader, Pein. Their relationship could range from mutual respect to outright hostility depending on Naruto's actions and goals within the organization.
His relationship with Sasuke would become even more complex. Sasuke might be suspicious of Naruto's motives for joining Akatsuki, thinking he has truly turned to the 'dark side'. Or, they could end up on opposite sides of a conflict within Akatsuki itself if their goals within the organization differ.
Naruto joining Akatsuki in fanfiction would turn his relationships upside down. His friends in the Leaf would initially feel betrayed. However, some might start to question if there's more to Naruto's decision. His relationship with Akatsuki members would be a mix. He'd be constantly in a tug - of - war with Itachi, who has his own plans regarding Naruto. And his interactions with Pain would be intense, as Pain represents a very different ideology from Naruto's. Naruto would have to struggle to find common ground or at least a way to coexist with these new 'comrades' while still holding onto his own values.
His relationships with his old friends in the Hidden Leaf would become extremely strained. They would see him as a traitor. For example, Sakura might be heartbroken and angry at him. Kakashi would be disappointed. However, within Akatsuki, he could form new relationships. He might become friends with some of the members who have a similar background of being misunderstood. For instance, he could bond with Hidan over their strong beliefs, though their beliefs are very different in nature.
His personality might become more guarded. He'd be surrounded by people who are mostly out for themselves or have very different values from him. So, he'd need to be more cautious in showing his true self.
Naruto's relationship with Kisame might become an interesting one. At first, Kisame would likely be very suspicious of Naruto. But as time goes on, Naruto's determination and strength could earn Kisame's respect. With Itachi there, he might be more open - minded towards Naruto. As for Kakuzu, Naruto would probably constantly clash with him due to Kakuzu's money - loving nature. Naruto would try to convince him that there are more important things than wealth. And with Sasori, Naruto would be horrified by Sasori's use of human puppets and would try to make him see the value of human life.
If Naruto is banished to Suna, his relationships will shift significantly. In Konoha, he had friends like Sakura and Shikamaru. But in Suna, he'll be starting from scratch. With Gaara, their relationship could deepen as they both understand the pain of loneliness. Naruto could also become a mentor - like figure to some of the younger Suna ninjas. His relationship with the Suna elders might be a bit tricky at first, as they would need to trust him, but over time, it could grow into respect and mutual cooperation.
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.
If Naruto was trained by the Akatsuki in fanfiction, his relationships would be completely transformed. For starters, his relationship with Kakashi would be strained. Kakashi has always been Naruto's mentor in a way, and seeing Naruto side with the Akatsuki would be a shock. His friends like Sakura and Shikamaru would also be confused and probably try to bring him back to the 'right side'. And his relationship with the villagers of Konoha would turn sour as they would fear his new - found Akatsuki - related powers.
His relationship with Sasuke would be very interesting. Sasuke, who has his own issues with the village, might see Naruto's banishment as another sign of the village's corruption. They could end up teaming up in a different way than before. With Sakura, she might be conflicted. She loves the village but also cares about Naruto. She could be one of the ones trying to bring Naruto back.
