If Naruto becomes a hunter nin in the fanfic, his sense of justice could become more complex. As a hunter nin, he'd be exposed to different shades of right and wrong. He might not be as quick to judge someone as he used to be. Instead of simply seeing enemies as bad guys, he'd start to understand the reasons behind their actions. This could make him more empathetic but also more calculating in his approach to dealing with threats. Also, his normally boisterous nature would likely be toned down to avoid attracting unnecessary attention.
Naruto's personality would likely change in several ways. His impulsiveness would have to be curbed. In Konoha, he could sometimes act on a whim, but as a hunter nin, that could get him killed. He'd need to be more patient, waiting for the perfect moment to strike or gather information. His loyalty would also be tested in new ways. He'd have to balance his loyalty to Konoha with the loyalty expected in the hunter nin community. This could lead to internal conflicts within him, making him more introspective and less carefree as he tries to figure out where his true loyalties lie.
Naruto's personality would likely become more patient. As a medic nin, he would need to be calm and focused during treatments. His impulsiveness would probably decrease as he realizes that any hasty move could harm a patient. He might also become more empathetic, understanding the pain and suffering of others on a deeper level.
If Naruto becomes a Hunter Nin in fanfiction, his personality would change significantly. He'd be more calculating. His usual impulsive nature would have to be toned down because one wrong move as a Hunter Nin could mean disaster. He might also become more solitary, used to working alone in the shadows rather than in a team. His sense of humor might also be more subdued as he takes on this serious and dangerous role.
Naruto would probably be more patient. As a medic nin, he has to be careful and precise, which would require him to rein in his impulsive nature. He'd also be more empathetic, understanding the pain of others on a deeper level since he's responsible for healing them.
Naruto's character would likely become more stealthy. Instead of his usual brash and loud approach, he'd have to learn to move in the shadows. His sense of justice would still be there, but he'd have to achieve it in a more covert way.
If Naruto were to become an angel in fanfiction, his personality would experience a significant transformation. His boisterous nature might be toned down a bit as he takes on a more solemn and wise demeanor. He would still be the kind - hearted Naruto we know, but his understanding of good and evil would be deeper. His compassion would extend not only to his friends and villagers but also to his enemies. He would strive to redeem them rather than simply defeat them, seeing the potential for good in everyone, which is a very angel - like trait. His sense of justice would also be more refined, based on a celestial understanding of right and wrong rather than just the ninja code.
Naruto might become more reserved. Princes are often expected to be composed, so he'd have to tone down his exuberant nature. But he'd still keep his kind heart.
Naruto's usually positive and energetic personality would likely become darker. He might be more brooding as a Death Knight. His sense of humor would probably be tinged with a bit of morbidity. However, his core of loyalty and protectiveness would still remain, just expressed in a different way. For instance, he would be more willing to use extreme measures to safeguard his village and friends.
Naruto's personality would adapt to fit the new role. His existing positive traits like his courage and his ability to make friends would help him in the Green Lantern Corps. He'd be more of a team player perhaps, learning to work with beings from all over the universe. His impulsive nature might still be there, but he'd learn to control it better with the discipline that comes with being a Green Lantern. And his overall goal would shift from becoming Hokage to being a great Green Lantern and protecting the cosmos.
He might become more cautious. Tsunade is a more calculating ninja compared to some of Naruto's previous mentors. So Naruto could start to think before he leaps, rather than just charging into battle head - first all the time.
His personality would become more reserved. As an assassin, he couldn't be as open and friendly as he used to be. He'd have to keep his emotions in check to avoid being detected.
