In his relationship with his mentors, it might change the dynamic of how they guide him. Instead of using physical gestures like a hand on the shoulder for reassurance, they would have to rely more on verbal communication. This could make the bond-building process more challenging as physical touch is often a way to convey closeness and trust in these relationships.
Even with his mentors or senseis, his fear can be a problem. They might want to guide him physically in training, like correcting his stance by touching his arm or shoulder. But Naruto's fear could make him resist this kind of guidance, which could slow down his progress in learning new techniques.
In a romantic relationship, it would be a major obstacle. His partner would have to be very patient and understanding. They would need to find other ways to show love and closeness, as physical touch is a common part of a romantic relationship. This could potentially slow down the development of a romantic relationship.
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.
Maybe it's related to his sense of independence. Naruto is used to relying on himself and having others touch him might make him feel like his personal space and autonomy are being invaded. He's always been on a journey to prove himself, and being touched could be seen as a form of interference in that self - discovery process.
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.
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 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 terms of his rivals, like Sasuke, Sasuke might view Naruto's new hairstyle as a sign of him trying to be different or better. This could either fuel their rivalry more or, in an interesting turn, make Sasuke respect Naruto's confidence in changing his look.
