His relationship with Sasuke could become more complicated. Sasuke might see Naruto as more of a threat or a mystery now that he's part of an older being. It could also create a sense of jealousy if Sasuke feels that Naruto has gained some sort of unfair advantage.
His relationships with his friends would become more complex. For example, Sasuke might be jealous or in awe of Naruto's new power. Sakura might see him as more of a distant figure, someone she can't fully understand anymore. And his old teachers like Kakashi would be in a position of having to respect Naruto's new status while still trying to guide him in some ways.
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.
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 were an ancient god in fanfiction, his relationships would be transformed. His relationship with his teacher, Iruka, would shift from a mentor - student bond to something more like a prophet - deity relationship. Iruka might feel a great sense of pride but also a bit of unease in Naruto's presence. His friends in Team 7 would have to adjust. Naruto's new powers and status would make them reevaluate their own positions. They might feel a bit overshadowed, but also protected. And as for his enemies, they would be forced to either submit or plot more deviously against him, knowing that he is now an ancient god with powers they can't fully comprehend.
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.
His relationship with Sasuke would likely be very different. Sasuke might be more in awe of Naruto, but also feel a greater sense of distance. They would no longer be just rivals, but there could be a new power dynamic where Naruto is in a much higher position.
His relationships would be very different. He wouldn't have the same connection with Jiraiya, for example. Instead, he might be mentored by an Iwagakure ninja. His relationship with the other villages would be more strained, as Iwagakure has a different history of relations with them. And his relationships with his peers in Iwagakure would be based on the Iwagakure way of life.
His relationships with his friends in Konoha would become more complicated. They might be suspicious of Medusa and worry about Naruto being influenced by her. But at the same time, Naruto could try to convince them that Medusa is not all bad. With his enemies, they might be more afraid of him because of his connection to Medusa.
In the wider ninja world, his relationship with other villages would change. Some villages might see him as an even greater threat now that he has the Rinnegan, and might try to form alliances against him. However, Naruto being Naruto, he would use his new power to show that he still has the same kind - hearted goals. He would try to use the Rinnegan to bring about peace even more strongly, and over time, win over those who were initially suspicious.
