Suppose Naruto makes a communication gadget. This would strengthen his relationships as he can stay in touch with his friends more easily, especially those like Sasuke who are often away. They could share their experiences and feelings more frequently, deepening their bond.
One of the coolest gadgets Naruto could create might be a shuriken launcher that can be activated with a simple chakra pulse. This would allow him to send out a flurry of shurikens in quick succession without having to physically throw them all, giving his enemies less time to react.
If Naruto takes pills, it could strain his relationship with Sakura. She, as a medical ninja, might be worried about the long - term effects on his health and constantly try to persuade him to stop. His relationship with Sasuke could also be affected. Sasuke might see Naruto's use of pills as a sign of weakness or an unfair advantage, which could lead to more conflict between them.
For his relationship with Kakashi, it could be complex. Kakashi, having his own experiences with the Sharingan, would be in a unique position to guide Naruto. But at the same time, he might be worried that Naruto's new power could attract unwanted attention. Naruto's bond with the villagers could also be affected. Some might see him as more of an Uchiha than a Uzumaki now, and there could be those who fear his power. His relationship with Jiraiya, if he were still alive in the fanfic, would also change. Jiraiya would need to teach Naruto how to use this power for good and not let it corrupt him.
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.
It would likely make his relationship with Iruka even more important. Iruka was one of the first to show Naruto kindness, and with his parents' absence, he would cling to Iruka as a father figure even more. Naruto might also be more eager to prove himself to his peers. He would want to show that he doesn't need his parents and can be just as good or better than those with a normal family. This could lead to some over - competitiveness at times.
It might actually strengthen his relationships in some ways. His friends could see him as an even more powerful ally. Naruto, with these new powers, could protect them better. Sakura, for instance, would feel safer around him and this could lead to a deeper bond of trust between them.
If Naruto gets a new bloodline, his relationship with Sasuke could become even more complex. Sasuke might be jealous of Naruto's new power, or it could be a reason for them to team up again to explore the origin of the bloodline. With Sakura, she might see Naruto in a new light, either being more attracted to his new strength or being worried about the potential risks of the bloodline.
His relationships with his peers can become more intense. For example, with Iruka - sensei, Naruto might cling to him more as a father figure. With his teammates, he may be overly eager to prove himself worthy of their friendship. He could be more sensitive to any signs of rejection from them.
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.
