Naruto's friends could also be very protective of him. They might see the one - wing as a target for Naruto's enemies. Hinata would be especially concerned and would offer her support in any way she could. Kiba and Akamaru might see it as a new way for Naruto to help in battles, but they would also be ready to defend him if anyone tried to take advantage of his new - found 'ability'. Over time, Naruto's relationships would evolve as they all learn to accept and make use of his unique wing.
Well, some of his friends might be a bit afraid of him. Naruto would have to work hard to show them that he's still the same person, just with this new addition. Shikamaru, for example, would likely be thinking about the strategic implications of Naruto having a wing, while Choji might just be curious and want to touch it. Naruto's relationships would be tested as he tries to adapt to his new situation while maintaining his bonds with his friends.
His friends might be initially shocked. Sasuke could be both intrigued and a bit jealous of Naruto's new feature. Sakura would probably be worried about Naruto at first, constantly checking on him to make sure the wing isn't causing him any harm.
His relationship with Kakashi could also shift. Kakashi, being experienced, would be both intrigued and worried about Naruto having the Millenium Puzzle. He would try to guide Naruto in understanding and using it properly. Naruto would respect Kakashi's wisdom more in this scenario and would look to him for advice on how to handle the power and the responsibilities that come with the Millenium Puzzle.
His friends might be initially shocked. But Naruto being Naruto, they would soon accept it. Sasuke might see Naruto's alien heritage as a new way to gain power and become more interested in working with him again. Sakura would be worried about the potential dangers it could bring to Naruto, and be more protective. Shikamaru might find it all too troublesome at first, but then start to strategize on how to use Naruto's newfound abilities for the village's benefit.
His relationship with Sasuke might be different. With Kurenai's influence, Naruto could be more understanding and patient, which might help him better deal with Sasuke's issues. His bond with Sakura could also change as he may approach her in a more mature way, having learned from Kurenai about relationships.
His relationships would change a great deal. For example, with Sasuke, Naruto might not be as persistent in bringing him back. Gaara - like Naruto would be more likely to let Sasuke go his own way as he wouldn't be as emotionally attached in that warm, Naruto - way. With Sakura, he'd be less likely to tease her or be as protective. He'd be more distant and less involved in her problems. And with his other friends like Shikamaru and Choji, he might not engage in their usual banter. Instead, he'd be more of a loner among them, only interacting when necessary.
His friends might be initially a bit wary of his fox family. But as they get to know them, they could start to see the benefits. For example, Sakura might realize that the fox family's knowledge of herbs can help in her medical ninja training. Naruto's relationship with Sasuke could also change. Maybe Sasuke sees the power within Naruto's fox family and becomes more intrigued, leading to a different kind of rivalry or even cooperation.
His friends would be very cautious at first. For example, Sasuke might be more on guard, seeing Naruto as a potential threat. However, true friends like Shikamaru might try to understand what's going on and find a way to help Naruto control his new powers.
His relationship with Kakashi would also be affected. Kakashi would have to mentor Naruto in a different way. He would need to teach Naruto how to use the Byakugan effectively, which is different from what he's used to with Naruto's normal abilities. This could strengthen their bond as teacher - student, or it could create some friction if Naruto struggles to adapt to Kakashi's new teaching methods.
His friends would likely see him in a new light. They might respect him even more. For example, Sasuke might view Naruto as an even greater rival now that he has the status of a Sannin. And his other friends like Sakura would be proud of him and might rely on him more for difficult missions.
His relationship with Sasuke might become more complex. Sasuke, always the rival, might see Naruto's new overlord status as a challenge to his own power and ideals. They could have more intense ideological battles.
His relationship with Sasuke could become more competitive yet respectful. They'd both see each other as equals in a new way. Sasuke might start to see Naruto as a real rival worthy of his attention, and Naruto would be more confident in their interactions.
