He could develop a sense of responsibility towards the power the arm holds. Since Danzo misused power, Naruto would strive to use it for good. This could lead to him becoming more mature and strategic in his approach to protecting the village. For example, he might study Danzo's old battle strategies stored in the arm's memories and adapt them to his own fighting style, all while maintaining his core belief in friendship and loyalty.
Naruto's character might also experience a growth in his understanding of the grey areas in life. Danzo's actions were not all black and white, and with his arm, Naruto gets a closer look at that. He could become more empathetic towards those who have made mistakes in the past while still firmly standing against injustice. This new - found understanding could make him a more well - rounded and respected leader in the village.
Naruto's character would likely become more reserved. Danzo's training might make him less trusting. He would probably be more calculating in his actions, weighing the benefits for the village more strictly. He might also be more inclined to use force or manipulation to achieve his goals, which is quite different from his original self.
His character would become more complex. He'd likely be more secretive at first, having to keep Danzo's teachings and missions under wraps. But his core values of protecting his friends and the village would still be there, just expressed in different ways as he navigates the morally grey area that comes with being Danzo's apprentice.
His development would be a tug - of - war between Danzo's influence and his own innate goodness. On one hand, Danzo could instill in him a sense of loyalty to the village at all costs. On the other hand, Naruto's natural desire to make friends and bring people together would constantly fight against that. So, his character might be a complex blend of secrecy and warmth.
Naruto's character might become more cautious. Since Kamui is a very powerful and somewhat unpredictable ability, he would need to be more careful when using it. For example, he might hesitate at first, not wanting to accidentally send himself or his friends into the wrong dimension.
Naruto might become more of an isolationist. Danzo was not one to form close bonds easily. So Naruto could be more reserved and keep to himself. However, his natural urge for connection might still be there, and he'd struggle between his upbringing and his true nature. He could start off as a loner but gradually learn to open up as he experiences different things in the village and realizes that not all relationships are like the ones Danzo had.
Naruto may become more cautious. With a prosthetic arm, he realizes his vulnerability more. He might start to think more strategically before jumping into battles. For example, in a fight, he won't just rely on his brute strength but use the unique features of his prosthetic arm to his advantage.
His relationships could change. His friends might be in awe of his new form, and some might be a bit intimidated at first. But as they see Naruto is still the same person deep down, they would support him. Enemies, on the other hand, would view him as an even greater threat, which would put more pressure on Naruto to protect those he cares about. He would also have to learn to control his new power so as not to accidentally harm his friends with the wings.
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.
Naruto's character would also develop in terms of his relationships. His friends might view him differently, some with awe and some with a bit of fear. He would have to work hard to maintain those relationships. With his enemies, he would be seen as an even greater threat. But Naruto would use this new perception to his advantage. He would try to use the fear of his Jagan Eye power to deter potential attackers and also to broker peace deals when possible. He would grow into a more complex and mature character as he navigates the challenges of having this new power.
Naruto's character would likely become more confident. Having the Rinnegan, a powerful and rare dojutsu, would give him an edge in combat and in understanding the world around him. His skills in sealing would also make him more versatile. He might become more of a thinker, as he has to combine the two abilities effectively. For example, when facing a difficult situation, he would first analyze it with the Rinnegan and then come up with a sealing solution.
