In fanfiction, how can the character of Naruto being an emotionless tool affect his relationships?

Well, it would be a huge blow to his friendships. Naruto's friends are drawn to his big heart and strong emotions. An emotionless Naruto would not respond in the same warm way. He might not share in their joys or sorrows. Sakura, for instance, would miss his determination and the way he used to encourage her. His friends would have to work hard to reach out to him, but they may also start to drift apart because the emotional connection is no longer there.

It would have a huge negative impact. Naruto's friends have come to rely on his emotional support and his ability to inspire them. Without his emotions, he might not show the same enthusiasm in helping them. His friendship with Kakashi would also change as Kakashi has guided Naruto in part based on his emotions and his will to protect his friends. Naruto might seem distant and unresponsive, causing his friends to feel rejected.

His relationships take a big hit. His friends like Sakura and Shikamaru would find it hard to connect with him. Sakura, who's used to Naruto's warm and often goofy self, would be at a loss. Naruto's lack of emotion means he won't show the same level of care or enthusiasm towards her. With Shikamaru, their conversations would be very different. Shikamaru is used to Naruto's emotional outbursts and quick decisions based on feelings. Now, Naruto would be more reserved and logical, which could strain their friendship.

With his friends, it might create a sense of shock. His friends who have always supported his dream of being Hokage would be surprised. Some might be disappointed, like Sakura who has seen Naruto's growth towards that goal. But others, like Shikamaru, might understand his decision and still support him in whatever he chooses to do. With his family, if he has a family at this point, it could bring a sense of relief as they may not want him to be in such a dangerous and stressful position.

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.

The Naruto's merman bloodline can greatly impact his relationships. If we consider his relationship with the village elders, they might see him as a potential threat or an asset depending on how they view his new abilities. They could try to use him for their own purposes, like sending him on dangerous underwater missions. With his peers, some might envy his unique powers, while others could be inspired by him. And when it comes to his family - like relationship with Iruka - Iruka might worry about Naruto being in a world that doesn't fully accept his merman side and try to protect him while also encouraging him to embrace his new identity.

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 Naruto fanfiction with the Kaiju bloodline, it can have a huge impact on relationships. If a character has this bloodline, those who are power - hungry might try to use them or manipulate them for their own gain. This can lead to a lot of mistrust. However, among true friends, it could be a source of admiration. They might see the unique abilities as something that can protect the village and be proud of the character. Also, in romantic relationships, the Kaiju bloodline could be both a draw and a concern. A partner might be attracted to the power but also worried about the danger it brings.

With Kakashi, Naruto's lack of emotions would mean he no longer has the same student - teacher bond. Kakashi is used to Naruto's determination and exuberance. Without emotions, Naruto would be like a different person. He'd follow Kakashi's orders mechanically without the usual eagerness and the relationship would become more of a cold, professional one.

His relationship with Sasuke would become very strained. Usually, they have a complex bond based on rivalry and friendship, but as an emotionless killer, Naruto would see Sasuke more as a target or an obstacle. He wouldn't care about Sasuke's own goals or feelings.
