Naruto's relationship with the village elders would be strained. Since he'd be at Itachi's age, he might be more aware of the village's darker secrets. He could be more critical of the elders' decisions, especially if he found out about any underhanded dealings related to the Uchiha clan. With his friends like Shikamaru and Choji, he'd be more of a leader among them, as his maturity level would be higher. They might rely on him more for tough decisions and look to him for guidance in dangerous situations.
His relationship with Sasuke would be very different. Instead of being a peer trying to bring Sasuke back, he'd be more like an older figure. He might be someone Sasuke looks up to or even fears because of his power and knowledge at that age. Naruto would also have a different relationship with Kakashi. He'd probably be more of an equal to Kakashi in terms of combat ability and strategic thinking.
His relationship with Sasuke would become extremely complex. Sasuke might see Naruto as a reminder of Itachi, which could stir up a mix of emotions like anger, envy, and also a strange sense of kinship. Naruto, on the other hand, might try to use Itachi's power to understand Sasuke better, but this could be misinterpreted by Sasuke as Naruto trying to take on the role of Itachi in his life. With his friends like Sakura and Kakashi, they might be initially wary of Naruto's new power. Sakura might worry that Naruto is losing himself to Itachi's power, while Kakashi would be more cautious and observant, trying to guide Naruto to use the power in a positive way.
Naruto's relationship with the other Leaf Village ninjas would also shift. Some might be suspicious of his new - found admiration for Itachi, especially those who were directly or indirectly affected by Itachi's actions. However, others who understand Itachi's true motives, like Kakashi, might support Naruto. This could create a complex web of relationships within the village, with Naruto at the center trying to balance his new beliefs and his old friendships.
His relationship with Sasuke would be completely different. Instead of being rivals, Sasuke might see Naruto as a sort of replacement for Itachi, which could lead to a very complex dynamic. Maybe Sasuke would be drawn to Naruto in a strange way, not sure if he should hate or befriend him.
In terms of his romantic relationships, if there was a budding relationship with Hinata, for instance, his new status as a jounin could either strengthen their bond as she admires his achievement, or it could create some distance as he has more duties and less time for personal matters.
His relationship with Sasuke would be very different. Instead of being rivals, they could become comrades more quickly. Since Naruto has been trained by Itachi, Sasuke might see Naruto in a new light and be more willing to work with him. With Sakura, Naruto might seem more distant at first because his new training makes him more focused on bigger threats. But eventually, she would come to respect his new power and abilities. His relationship with Kakashi could also change. Kakashi might be a bit wary of the new Naruto trained by the Uchiha, but also proud of how much stronger he has become.
His relationship with Sasuke might change. Sasuke might initially be confused or even critical of Naruto without his headband. But as Naruto shows his determination without it, Sasuke could gain a new respect for him. With his friends like Sakura, they might be more protective of Naruto, fearing that others will target him without the symbol of his ninja status.
His relationship with Sasuke would be very different. Instead of being rivals, they might become more like comrades or even brothers in arms, as Itachi and Sasuke were related. Naruto would probably be more understanding of Sasuke's thirst for power and revenge, and might try to guide him in a more Itachi - like way. With Sakura, Naruto might become more distant, as Itachi was not very close to female characters in the original story. And with his other friends like Shikamaru or Kiba, Naruto would likely be more reserved and less of the loud, exuberant self they knew, which could cause some confusion and concern among them.
Well, in terms of his relationship with Sasuke, it could go either way. Sasuke might see Naruto's transformation into the Kyubi as a challenge to his own power and strive to become stronger. Or, he could be intrigued by this new form of Naruto and consider teaming up with him again. Regarding his relationship with the villagers, those who once feared him for having the Kyubi inside him might now fear him even more in his Kyubi form. However, some of the younger generation might look up to him as a symbol of strength. And his relationship with Hinata would also be affected. Hinata might be more determined to protect Naruto, but also feel a bit inadequate compared to his new - found power.
In terms of his relationship with the villagers, those who once bullied him for being an orphan and having a different look (with his blond hair) might be even more hostile if his red hair makes him stand out more. However, there could also be some villagers who see his red hair as a sign of something special and start to respect him more, which could lead to a shift in how Naruto views the village and his place in it.
His relationship with Sakura would change a lot. Sakura might be more protective of Naruto as a cat, seeing him as a cute and vulnerable creature. She might take on a more motherly role towards him. With Kakashi, Kakashi would probably be amused by Naruto's cat form at first, but then he'd start to worry about how to turn him back. And as for his friends in general, they'd have to communicate with him in different ways, like through body language and meows.
