His relationship with the village as a whole would also be affected. Some villagers might be suspicious of his seclusion, thinking he was up to something dangerous. But once they see the stronger and more mature Naruto, they could start to respect him even more and see him as an even greater protector of the village.
His relationships with his friends might have become strained. Since he was in seclusion, he wouldn't have been able to interact with them regularly. They might have felt abandoned and been initially angry or hurt.
His relationship with Sasuke could change. Sasuke might be initially jealous of Naruto's new power. But as they face challenges together, Sasuke could come to respect it. For example, if Naruto uses telekinesis to save Sasuke from a dangerous situation, Sasuke would see the value of it.
In fanfic, the Naruto robot body can have a significant impact on his relationships. His friends might initially be shocked or even a bit distant. For example, Sakura might be hesitant to get close to him at first because he seems so different now. However, as time passes, they could come to accept and even admire his new form. His enemies, on the other hand, might see him as an even greater threat. They would have to adjust their strategies when facing a Naruto with a robot body that has enhanced abilities. Some might be more cautious, while others might be more aggressive in trying to destroy this new and powerful version of Naruto.
When Naruto releases the Kyuubi in the fanfic, it might change his relationship with his sensei, Kakashi. Kakashi would be on high alert, ready to step in if Naruto loses control. At the same time, he would be guiding Naruto on how to better manage the Kyuubi's power. This could bring them closer as Naruto learns from Kakashi's experience. And Naruto's relationship with the other ninja in the village would also shift. Some would look up to him more as a powerful force to protect them, while others might be jealous of his new - found strength.
With Sasuke, it could go either way. Sasuke might see Naruto as an even greater rival now that he has the Kyuubi's power. Or, he could respect Naruto more for being able to harness such a great power. But overall, it would add a new dynamic to their complex relationship.
Some of his friends might be worried at first. They know Zabuza was a dangerous enemy before. But Naruto could convince them that he'll use the sword for good.
His relationships with his friends like Sasuke and Kakashi would also be affected. Sasuke might understand Naruto's decision on some level, having also left the village before. Kakashi, on the other hand, would be worried about Naruto. He might try to find him and bring him back. This could create some tension between Naruto and Kakashi as Naruto tries to assert his independence.
In this type of fanfic, Naruto's friends might become more protective of him. They see him as being alone in the love aspect and might try to fill that void in other ways, like by being even more supportive and spending more time with him. This could lead to some really heartwarming friendships.
With Sasuke, it could either drive a wedge or bring them closer. If Sasuke blames himself for Naruto getting injured while protecting him, he might distance himself out of guilt. On the other hand, it could also make Sasuke realize how much Naruto means to him and he could become more committed to their friendship.
His apathy can strain his relationships. His friends might feel neglected. For instance, Sakura could be confused and hurt as Naruto no longer shows the same eagerness to be part of the team.
The black chakra could make other characters view Naruto with suspicion. His friends might be worried that this new power is corrupting him, which could strain their relationships. For instance, Sasuke might see it as a sign that Naruto is becoming more like the enemies they've fought.
