With Iruka, I think Iruka would be very protective. He already cares about Naruto, and the wings would just make him more concerned for Naruto's well - being. As for Sakura, she might be a bit shocked at first but then would see it as just another part of Naruto and continue to have her normal feelings for him. With Kakashi, he would probably be very interested in how Naruto could use the wings in combat and training.
His relationship with the villagers would be complex. Some might see him as even more of a threat or oddity. But others, especially the younger generation, could be inspired by him. His friends like Shikamaru would probably be lazy about showing their interest but deep down be curious. And Choji would likely offer Naruto some of his snacks as a sign of acceptance. His bond with Hinata could also change. Hinata might be more shy around him because of his wings, which are such a striking and different feature.
His relationship with Sasuke might become more competitive. Sasuke, seeing Naruto with this new power of wings, would feel the need to become stronger in his own way. They could have more intense battles or training sessions. With Sakura, she might be initially shocked but then would become more protective of Naruto, fearing that his new wings might attract more dangerous enemies. She could also help him with any medical issues related to the wings if they cause any strain on his body.
His relationship with Sasuke would likely be affected. Sasuke might be both intrigued and wary of Naruto's hollow abilities. They could have new reasons for rivalry, like Sasuke wanting to prove he's stronger despite Naruto's unique powers. Or, they could end up teaming up earlier to figure out what Naruto's hollow nature means.
If Naruto were born an Uchiha, his relationship with Sakura might be affected. Sakura might be more drawn to him initially because of the allure of the Uchiha clan. However, Naruto might be more focused on restoring the Uchiha name and proving that they are not all bad. His relationship with the villagers would be complex. Some would be fearful, while others might hope that he could use his Uchiha powers for the good of the village.
If Naruto has wings, his hair might seem to flow more gracefully in the wind as he flies. His eyes could glow a different color when he uses the power associated with the wings. Also, the wings themselves could be unique. They might be made of some kind of chakra - like substance, giving them a shiny or translucent look. And there could be markings on the wings that are related to his Uzumaki heritage or some new power he has acquired.
His relationship with Sasuke would likely be different. With Naruto being a sage from birth, Sasuke might see him as an even greater rival or, perhaps, someone to look up to more. Naruto could use his sage - like wisdom to better understand Sasuke's pain and motives, and might be more effective in bringing Sasuke back to the village earlier.
His friends might be initially surprised. Sasuke could be a bit jealous at first as Naruto has this new, cool ability. But Sakura would probably be worried about whether it's safe for Naruto. Over time, they would adapt and Naruto would use his wings to help his friends in battles or to reach places faster for rescue missions.
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.
His relationship with Sasuke would be greatly affected. Sasuke might see Naruto as a completely different person now that he has become the Nine - Tails. There could be a sense of fear or at least a new level of caution from Sasuke. They might have to re - establish their bond, as Naruto's new form could be a threat in Sasuke's eyes.
