Some of his friends might be a bit more cautious around him. For example, Sasuke might be more on guard, as he has a history with the Uchiha and Madara's power is something he'd be very aware of. But Naruto would still try to keep their friendship intact.
Naruto's relationships would be a complex mix of respect, fear, and admiration. His peers in the village would look up to him even more, but also be a bit intimidated. His enemies would be far more afraid of him. Naruto would have to work hard to maintain the bonds he has, while also using Madara's power to protect those he cares about. He might also attract new allies who see his newfound strength as a means to achieve their own goals.
His relationship with the village elders would be very different. They might be more fearful of him and try to keep him in check. However, Naruto would still have his own values and would strive to prove that he can be trusted with this new power. His relationship with Hinata could also be affected. She might be worried about the changes in Naruto and how this power could put him in more danger.
If Naruto had Madara's memories in fanfiction, his relationships would shift in multiple ways. With his friends, he might seem a bit more distant at first as he tries to process Madara's often - solitary and distrustful view of others. However, he'd also be more protective, using Madara's knowledge of the world's dangers. His relationship with the village elders could become more strained. Since Madara had a negative view of Konoha's leadership at times, Naruto might start to question some of their decisions more, based on those memories.
With his friends in Konoha, they would be initially worried. But those who truly know Naruto, like Shikamaru and Sakura, would support him in his decision. They would help him adjust to not having that power and encourage him to find his own path again. However, some of the younger ninjas who looked up to Naruto because of his great power might be disappointed at first.
With Kakashi, Naruto's relationship could change a lot. Kakashi has always been a mentor to Naruto. But if Naruto is Madara's grandson, Kakashi might be more cautious. He has a history with the Uchiha and Madara in particular. So, he could be more watchful of Naruto, which might make Naruto feel a bit alienated from his old teacher. At the same time, Kakashi could also see it as an opportunity to guide Naruto in a way that prevents him from going down Madara's dark path.
With his friends in the Hidden Leaf, Naruto would become more distant. His new attitude would make them question his loyalty and motives. Sakura, who has always cared for Naruto, would be disappointed and confused. She might try to bring back the old Naruto, but his Madara - like attitude would make him resist her attempts. His relationships with his sensei, like Kakashi, would also be strained as Kakashi would not be able to understand or tolerate Naruto's new, more extreme views.
His relationships with his friends might change a bit. His friends would be both amazed and maybe a little bit intimidated by his new powers. For example, Sasuke might see Naruto as an even greater rival now. And his relationship with his sensei, like Kakashi, would also be different as Kakashi would have to help Naruto understand and control these new alien powers.
Well, with his friends, Naruto's relationships would change significantly. They would be confused and concerned. Sakura might try to use her medical skills to see if there's something physically wrong with Naruto that's making him act like a mini Madara. Kakashi would be on high alert, not knowing if Naruto could be a threat. Naruto's relationship with the younger generation, like Boruto and the others, would also be affected. They would look at him differently, and Naruto would have to deal with their disappointment and fear. He would have to work hard to regain their trust and show that he's still the Naruto they know deep down.
His relationship with Sasuke might change. Sasuke might be more intrigued or even a bit jealous of Naruto's new power. Naruto could use the Shinigami eyes to better understand Sasuke's inner turmoil, which is often related to his own spiritual and emotional state.
His relationship with Sasuke might become more complex. Sasuke might see Naruto in a different light and be more protective or confused about his feelings. With Sakura, they could become closer as sisters - like friends, sharing more girly things and having different conversations. And his male friends like Shikamaru might be a bit more hesitant around him at first, but then adapt and joke about it in their own way.
His relationships with his sensei, like Kakashi, would also be affected. Kakashi would be very cautious and would want to train Naruto to make sure he can use the power responsibly. He might also be researching about Scorpion's power to better guide Naruto, which could lead to some interesting teacher - student moments where Naruto learns more about his new power and how to use it in harmony with his existing skills.
His confidence would skyrocket. Naruto has always been confident, but with Madara's power, he'd have a new level of self - assurance. He'd know he could handle almost any threat. His sense of responsibility would also grow. Since he has such great power now, he'd feel an even greater obligation to protect his village and friends.
