His character could develop a more nuanced view of the ninja world. In an organization, he'd interact with ninjas from different backgrounds and with different ideologies. This would make him more understanding and less quick to judge. He might also become more cautious as he realizes that the actions of the organization could have far - reaching consequences on the world at large. For example, if the organization is involved in some shady deals, Naruto would have to be careful not to get dragged into unethical behavior.
If he joins an organization, Naruto might become more strategic. Since organizations usually have a set of goals and plans, he'd need to think more about the overall mission rather than just charging in like he used to. His leadership skills could also improve as he might be given tasks to lead a small group within the organization.
His character would likely become more conflicted. He has always been a positive and determined person, but being around Orochimaru would expose him to a lot of darkness. He might start to question his own beliefs and values. For example, he may become more ruthless in battle as he adopts some of Orochimaru's combat styles.
Naruto's character would become more complex. His initial naivete about the world's darker aspects would quickly disappear. He'd become more cynical as he witnesses the actions of the Dark Brotherhood. His relationships with his old friends in Konoha would also be strained as they might not understand his new allegiance.
His character could become more complex. He'd have to balance his own values from Konoha with the new ones in the Covenant. This internal struggle would likely make him more mature. For example, he might question his previous beliefs about power and leadership.
His character could become more adaptable. In Kumo, he'd be exposed to different values and ways of life. This would make him more open - minded. For instance, he might start to view the concept of power in a new light, as Kumo has a different emphasis on strength compared to Konoha.
Naruto's character would become more conflicted. His usual bright and positive attitude might be dampened by the darker environment of Sound. He'd start to question his values. For instance, he might be forced to participate in battles or actions that go against his beliefs in Konoha.
His character would likely become more diplomatic. Since the Fire Nation has a complex political structure, Naruto would have to learn to navigate it. He might become more calculating in his actions, but still retain his core values of friendship and justice.
His character might become more complex. He would be exposed to the darker side of the ninja world more directly. He could develop a more cynical view while still holding onto his core values.
His character would develop in multiple ways. Initially, Naruto would be a fish out of water in Otogakure. He's used to the hustle and bustle and the general positive (although with some underlying issues) atmosphere of Konoha. In Otogakure, he would have to be more guarded. His social skills would be put to the test as he tries to make friends or at least allies. He would also become more self - reliant as he doesn't have the same support system as in Konoha. His view on power would change. In Konoha, power was often seen in the context of protecting the village and friends. In Otogakure, power seems to be more about personal gain at first. Naruto would have to decide which view of power he wants to adopt. Over time, he could either bring some of Konoha's values to Otogakure or be changed by Otogakure's values.
Naruto's character would likely become more conflicted. He has always been on the side of good, and joining Orochimaru, even if for a good reason, would put him in a morally gray area. His view of power might change as he is exposed to Orochimaru's unorthodox ways of obtaining it.
His character would likely become more conflicted. He'd be torn between the values he grew up with in Konoha and the new, darker values of Akatsuki. His development would be a struggle between his innate goodness and the evil around him.
