His confidence might grow faster. Since the Sharingan gives an edge in combat, Naruto would likely win more battles early on, which would boost his self - esteem. He might also become more introspective as the Sharingan has some psychological aspects to it.
If Naruto was born with the Sharingan in fanfiction, his character would develop in some interesting ways. He would be more of an enigma to those around him. The Sharingan is a symbol of power and mystery in the Naruto world. Naruto having it would make him stand out even more. He might start to question his identity more deeply, wondering why he, a non - Uchiha, has this powerful ability. This could lead to a more complex and mature Naruto as he tries to figure out his place in the ninja world, not just as the Jinchuriki of the Nine - Tails but also as someone with the Sharingan.
Naruto's confidence would likely increase significantly. Having such a powerful and unique ability would make him feel more capable of protecting his village and friends. He might become a bit more reserved at first, as he tries to understand and master the new power, but eventually, he would use it to be more assertive in battles and in diplomatic situations as well, knowing he has an ace up his sleeve.
Naruto would likely become more introspective. The Rinne Sharingan is a very powerful and somewhat mysterious ability. Having it would force Naruto to understand more about the deeper aspects of chakra and the ninja world. He might become a bit more cautious as he realizes the great power he holds and the potential for it to be misused.
His character would develop in terms of leadership. With the Rinne Sharingan, Naruto would have even more power at his disposal, which could make him a more formidable leader. He could use the knowledge and abilities it gives him to better protect his village and make more informed decisions. For example, he could use its precognitive abilities (if it has any in the fanfiction) to anticipate threats and plan accordingly. Also, he might become more isolated as he tries to master this new power, but in the end, it would make his bonds with his true friends even stronger.
Naruto would likely become more introspective. The Mangekyo Sharingan often comes with a lot of emotional baggage in the Naruto universe. So, Naruto might start to question his own identity more, especially since this power is from a clan he has no blood relation to. He could also become more cautious as he learns about the potential dangers of misusing the Mangekyo Sharingan.
Well, Naruto having the Mangekyou Sharingan and Rinnegan in fanfiction would change him a great deal. His character development would involve a lot of self - discovery. He'd be constantly exploring the limits of these powers, which would take him away from his home village more often. This would make him miss his friends and family, adding a new layer of emotion to his character. He'd also have to deal with the envy and fear of others who might see him as a threat because of his powerful eyes. But through it all, Naruto would strive to use these powers for the greater good, and this would shape him into a more mature and respected ninja in the fanfiction world.
Naruto would likely face a lot of self - discovery. He'd have to figure out how to deal with the physical aspect of having wings, like learning to fly and not accidentally knocking things over. This would make him more aware of his body and how it moves. Emotionally, he might feel isolated at first, but as he gets used to his wings, he'd become more confident and see them as an asset.
Naruto's character would likely develop a strong sense of adventure. In the One Piece world, there are so many islands to explore and mysteries to uncover. He'd be eager to find out about the One Piece itself. His determination to be recognized would also take on a new form. Instead of being recognized as a great ninja in Konoha, he'd want to be known as a great figure in the One Piece universe, maybe as a hero who helps the oppressed. His loyalty would still be a big part of his character, and he'd form strong bonds with the friends he makes during his travels.
In Earthland, Naruto would be exposed to different forms of power like magic. This would make him question his own abilities and strive to improve. His character would develop in terms of his understanding of power. He'd also learn about the importance of cooperation in a different way. For instance, in battles against powerful dark mages, he'd realize that teamwork with Earthland's mages is crucial. His journey in Earthland would be about self - discovery as well as becoming a hero in a new world. He'd grow from a curious newborn in Earthland to a respected figure, respected for his unique skills and unwavering spirit.
His character would likely be more hardened. Growing up in clan wars means facing danger and betrayal often. He'd be less trusting at first. For example, he might not be as quick to befriend Sasuke as in the original. He'd have a 'survival first' mindset.
His sense of self - identity might be shaken. Ichigo has always been defined by his role as a Soul Reaper and his own unique powers in the Bleach universe. Adding the Sharingan would introduce a foreign element. He would have to figure out how this new power fits into his existing power set and his moral code. He might question whether he's still the same Ichigo or if this new power is changing him into someone he doesn't want to be. This internal struggle could lead to significant character growth as he grapples with his new identity.
