If Naruto joins the Fire Nation in fanfiction, his character would experience significant growth. He would be exposed to a new culture and set of values. This could make him more adaptable and open - minded. He may also develop a deeper understanding of power dynamics as he gets involved in the Fire Nation's affairs. His relationships with the people around him, both old friends from his original home and new acquaintances in the Fire Nation, would evolve in interesting ways.
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.
Naruto's character would go through a major transformation if he joins the Fire Nation in fanfiction. He would have to adjust to the Fire Nation's hierarchical society. This could lead to him becoming more assertive in order to make his voice heard. His ninja skills would be put to different uses, perhaps more focused on internal security and political protection. His ideology might also be influenced by the Fire Nation's history and beliefs. However, he would still strive to uphold his own beliefs and might even try to merge the best of both worlds, creating a new kind of leadership within the Fire Nation.
The story would likely take a very different turn. Aang joining the Fire Nation could start with him being a sort of undercover agent, trying to figure out the secrets of the Fire Nation while pretending to be on their side. This could lead to some intense spy - like situations.
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 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.
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.
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.
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.
