Naruto's character could change in several ways. Firstly, he might become more secretive as he tries to figure out what the gun is without causing panic. He's always been an open book, but this strange discovery might make him hold back some information. Secondly, he could become a bit more of a loner as he delves into understanding the gun on his own. He might feel that his friends won't understand this new aspect of his world. Also, his sense of right and wrong could be challenged. The gun's lethality is different from his normal weapons, and he'd have to decide how and when it's appropriate to use it, if at all, which would be a big shift in his character.
Naruto might become more cautious. Guns are very different from ninja tools, and one wrong move could be fatal. So he'd have to think twice before acting impulsively, which is a big change from his usual head - first approach.
His relationship with his friends might change. Some of his friends who are more used to the 'old Percy' might be a bit shocked or even worried about his new weapon choice. On the other hand, he might attract new allies who are more into modern - day combat methods. Overall, his character would have to adapt to the new implications and responsibilities that come with using a gun.
Naruto would likely become more confident. Knowing he has a clan that accepts him would boost his self - esteem. He might not be as much of an outcast as in the original story, and this could lead to a less boisterous personality, as he doesn't have to constantly seek attention to be noticed.
It would likely accelerate his growth. Jiraiya is a very experienced ninja. With his guidance, Naruto would gain more confidence. For example, if Jiraiya found Naruto early on, he could teach Naruto better control of his chakra, which was a struggle for Naruto in the beginning. This would make Naruto more efficient in battles and less reliant on brute force.
His life would become much more exciting. Naruto would have a new creature to take care of, which is a big change from his normal ninja life. He'd need to learn about dragon care, which could lead him to new places and new knowledge. And he'd have a powerful friend once the egg hatches.
If Naruto found a devil fruit, it would open up a whole new world of possibilities for his adventures. He could travel to different lands in search of more knowledge about the devil fruit. Maybe he'd encounter other characters from different fictional universes who are also interested in devil fruits. His understanding of power and the world around him would expand. He'd no longer be just a ninja from the Hidden Leaf, but someone with a power that bridges different fictional concepts. This could lead to him becoming a sort of ambassador between the Naruto world and the world of One Piece - like elements introduced by the devil fruit.
His character would likely become more complex. Having a gun would give him an edge that he didn't have before, which could make him more confident or even a bit cocky at first. But he'd also have to deal with the moral implications of using such a deadly weapon. He's always been about protecting his friends and the village, but a gun is a very different kind of weapon compared to his ninja tools.
Naruto would likely be more conflicted. His usually bright and positive personality might be tempered by the knowledge of his dark heritage. He might become more cautious in using his power, knowing the destruction Thanos was capable of. He could also be more isolated as other characters might fear his potential for evil.
His character would change in several ways. For one, he'd be more independent as the Cheshire Cat is often a solitary figure. He might also become more mischievous, using his disappearing and reappearing to play tricks on people. His sense of humor would likely take on a more sly and enigmatic quality, different from his normal boisterous humor. And he'd probably be more in tune with his instincts, like a cat, rather than relying solely on his ninja training.
Naruto's character would change significantly. He'd likely be more self - assured as he grows up under Beerus. He may not have the same sense of community as he did in Konoha since Beerus is more of an individualistic being. He might also be more patient and less likely to jump into action without thinking, having learned from Beerus' more calculated ways.
