Naruto's relationships with other villages could also change. Some villages might see him as a threat, while others might see an opportunity to use him against Konoha. He might also meet shinobi from other villages who have had similar experiences of being ostracized, and form new bonds based on shared understanding. His status as a nukenin would put him in a unique position in the international shinobi community.
With his friends in Konoha, like Sakura and Kakashi, there would be a major shift. Sakura might initially be conflicted between her loyalty to the village and her friendship with Naruto. Kakashi, being a more experienced shinobi, might understand Naruto's reasons better but still be bound by his duties to the village. Overall, Naruto's departure as a nukenin would create a lot of emotional turmoil among his relationships.
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.
If Naruto becomes cold, his relationship with Hinata would be severely affected. Hinata, who loves him for his warm heart, might be at a loss. Naruto might start to push her away, not allowing her to get close. His friends from Team 7 might try to bring back the old Naruto, but his coldness would create a rift between them.
His relationship with his old friends like Sasuke would likely become more of an equal partnership. Since they are both highly skilled, they could collaborate on important missions. With Sakura, he might be seen as more of a respected colleague, and she could look up to him in a different way as a Jounin.
With his friends in Konoha, they might initially be shocked by his new appearance. But then, they would get used to it. Naruto's popularity among the villagers could skyrocket. People who once shunned him might now be more accepting. This could also change his relationship with Iruka sensei. Iruka would be proud of how Naruto has grown not just in terms of power but also in his appearance, and their bond could become even stronger as Naruto becomes a more respected figure in the village.
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.
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 friends in Team 7, Kakashi included, would be deeply concerned. They would try to figure out what made Naruto change. However, Naruto's coldness would make communication difficult. He might distance himself from them, seeing their attempts as interference. His relationships with the villagers would also change. People who once looked up to him might now be afraid of him, as his cold demeanor is a far cry from the hero they knew.
If Naruto becomes a Jigsaw fan in fanfiction, his relationships would change drastically. His friends and comrades in Konoha would be confused and concerned. They have always known Naruto as a kind - hearted and positive person. His newfound interest in Jigsaw's ways would seem out of character. For instance, his bond with Hinata would be severely tested. Hinata, who loves Naruto for his heroic and gentle nature, would be at a loss on how to deal with this new, darker Naruto. His relationships with the other ninja clans in the village would also become tense as they would view his new ideology as a threat to the village's peace and stability.
Well, when Naruto becomes the Death God in fanfiction, his relationship with Sakura would change. She might be more hesitant around him, as his new power is so otherworldly. And his bond with Kakashi would also be different. Kakashi, being a wise ninja, would try to guide Naruto in using this power responsibly. Naruto's relationships with the villagers would shift too. Some might worship him, while others could be suspicious of his new - found power.
