He would probably have a more menacing look. The bat wings would be large and leathery, perhaps a dark color like black or deep brown. His overall silhouette would be bulkier with the wings attached to his back. His clothes might need to be adjusted too, maybe with some slits or special fastenings to accommodate the wings when they're folded.
Naruto's appearance would change quite a bit. The bat wings would not only be a physical addition but also affect his body language. He might hunch over a bit more when he's on the ground to balance the weight of the wings. His skin could become a bit paler as if the wings are draining some of his natural color. And he might have a new symbol or mark on his back where the wings are attached, something that gives a clue about the origin of the wings in the fanfiction.
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.
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.
The angel wings could give Naruto enhanced mobility. He could fly above his opponents, making it difficult for them to land attacks on him. This would also allow him to quickly close the distance between himself and an enemy or escape from a dangerous situation.
His overall posture and movement would change too. With the wings, he would need to be more aware of his surroundings to avoid knocking things over with them. His gait might be different as he adjusts to the new weight and balance on his back. Also, his face might have a more 'otherworldly' look. Maybe his eyes would have a glint like a dragon's, or his skin could take on a slightly scaly texture near the base of the wings.
It's possible that Naruto's overall physique could be altered. Dragons are known for their strength and agility. So, Naruto might become more muscular and his movements more fluid and graceful. His body could also develop a natural resistance to extreme temperatures, whether it's the searing heat of dragon's fire or the cold of their lairs. This would allow him to endure harsh environments that would normally be difficult for a normal ninja.
Well, Naruto with Madara's hairstyle would look quite different. His usually spiky blonde hair would be replaced by Madara's long, dark hair. It might make him look more serious and less of the goofy, energetic Naruto we know. His face might seem more angular with that hairstyle, and it could also give him an air of mystery, like Madara had.
He might have some physical features similar to Tobirama. For example, his hair could take on a slightly different texture or style, or his eyes might have a different glint. Maybe his face would become a bit more angular, as Tobirama had a more defined facial structure compared to Naruto's usual look.
In fanfiction, if Naruto got Hashirama cells, his appearance could change in several ways. His body structure might become more like Hashirama's, which was relatively large and muscular. His facial features could also be affected, perhaps his jawline could become more prominent like Hashirama's. And there could be some greenish tints to his skin or his chakra, reminiscent of Hashirama's connection to nature through his wood release. This change in appearance would not only be a physical transformation but also a sign of the new power within him, which could also influence how other characters perceive him.
Well, when Naruto absorbs the Juubi in a crossover fanfiction, his appearance would be a visual representation of his new power. He could have some sort of chakra horns or spikes protruding from his body, similar to some of the forms of the tailed beasts. His eyes might become more slitted and have a more menacing look. The overall look would be a blend of Naruto's original appearance and the terrifying and powerful essence of the Juubi, making him look both familiar and yet completely different at the same time.
The face mask could be designed in a way that gives him a more intimidating appearance. If it has some sharp edges or a menacing pattern, it could make Naruto seem like a more formidable opponent. This change in appearance might cause his enemies to be more cautious around him, and his friends might also see a new side of him.
