When Naruto is banished and joins Akatsuki in a fanfic, his relationships take a huge turn. With the Hidden Leaf, it's all about broken trust. His friends who once stood by him would now consider him an enemy. His bond with Iruka, who was like a father figure, would be severely damaged. In Akatsuki, he'd have to navigate a world of dangerous and often morally ambiguous characters. He might find an unlikely friendship with Kisame, who might be intrigued by Naruto's positive energy. And his relationship with the leader of Akatsuki would be one of mutual suspicion at first. As time passes, Naruto would have to decide whether to fully embrace Akatsuki's ways or try to bring about change, which would further affect all his relationships.
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 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.
His relationship with Sasuke would become even more complex. Sasuke might see Naruto's joining of Akatsuki as a betrayal or a sign that Naruto has finally given up on Konoha. Naruto's old friends in Konoha, like Sakura and Kakashi, would be very confused and hurt. They might try to bring him back, but also be wary of his new Akatsuki ties. And within Akatsuki, Naruto would have to navigate relationships with members who have different motives and personalities, some of whom might not trust him at all.
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.
Naruto's relationship with his sensei, Kakashi, would be severely strained. Kakashi has always been a guiding figure for Naruto, and Naruto joining the Akatsuki would seem like a betrayal. However, Kakashi might also suspect that Naruto has an ulterior motive. As for his relationships with the other Konoha ninjas, they would be filled with suspicion and mistrust. But Naruto could also form new relationships within the Akatsuki. He might befriend some of the members who have a bit of good in them, like Konan perhaps, and together they could work towards a new future for the Akatsuki.
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.
His relationship with Sasuke would be greatly affected. Sasuke might see Naruto's move as a betrayal to Konoha and their bond. On the other hand, Naruto's relationship with Konan would become very strong as they are now comrades in Amegakure. He might also form new friendships with the shinobi of Amegakure who would look up to him for his power and his new ideas for the village.
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 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.
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.
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.
