His character would likely become more complex. With the Sharinegan, he'd have to deal with new responsibilities and a different kind of power. He might become more introspective as he tries to understand the origin and purpose of this new ability.
He would develop a new sense of self - confidence, not just in his own abilities but also in his place in the ninja world. The Sharinegan would give him an edge that he didn't have before, and he would use it to not only prove himself but also to inspire others. He would grow into a more well - rounded leader, using his new power to show that anyone can overcome challenges and use their unique gifts for the greater good.
Naruto would likely become more distrustful at first. He's always been so open and trusting of his friends, so this betrayal would shatter that. He might become more withdrawn, constantly second - guessing people's motives.
Perhaps in this fanfic, the Sharinegan is a power that is transferred to Naruto from a dying enemy. At first, he struggles to control it because it's so different from his normal chakra-based powers. But with the help of his friends like Sasuke and Sakura, he learns to master it. He then uses the Sharinegan to uncover secrets about the ninja world's past that are crucial for the future of all ninja.
His character could become darker. The once - cheerful and optimistic Naruto might turn cynical. He would start to question all the values he was taught about loyalty and friendship. For example, he might see his past friendships as a form of manipulation by the village. This new - found bitterness would be a major shift in his character.
His emotional side would be deeply affected. He might be more guarded and less likely to show his true feelings easily. He would see the world in a more cynical way at first. But as he grows, he could use his experiences to become more empathetic towards others who are also alone or neglected. For instance, he could start reaching out to orphaned kids in the village. His journey to becoming Hokage would also be different. Instead of having the typical family - inspired motivation, it could be a way to rewrite the story of neglect in his own life and in the village.
He would start to blend different cultures and values. The Jedi values associated with the lightsaber, like discipline and self - control, could start to influence Naruto. He might become more in tune with his spiritual side, similar to how Jedi connect with the Force. This could lead to new abilities and a deeper understanding of his own ninja powers, as he combines the teachings of the ninja world with those of the Jedi through the use of the lightsaber.
He'd become more empathetic towards creatures other than humans. Naruto is already kind - hearted, but having a Pokémon would expand his understanding of different species.
His character would likely become more complex. With the Tenseigan's power, he would face new challenges and responsibilities.
If Naruto got a kekkei genkai, his confidence would likely skyrocket. He's always been the underdog, and this new power would make him feel like he's on a more equal footing with his peers. He might become a bit more reckless at first, eager to test out his new abilities in battle.
Naruto would become more mature and responsible. He's used to being the wild and carefree ninja, but with a family, he'd have to think about others. For example, he'd be more cautious in battles because he has a family to go back to. Hinata would also grow, becoming a strong mother figure, teaching their children about the Hyuga clan's traditions while also being a loving wife.
Naruto would likely be more distrustful. Growing up without his parents and under Danzo's influence, he might not have the same sense of hope and determination that he had in the original story. He could be more cynical about the village and its leadership.
