Naruto's character may develop in a more diplomatic way. If the genie gives him the ability to influence the five great nations with a wish, he would need to learn how to handle political situations. He would have to consider the interests of all parties involved, not just his own village. This would make him more of a global - minded leader rather than just a local hero. And his interactions with the genie, who might be from a different world or have different values, would also force Naruto to be more open - minded and adaptable.
When Goku meets his family in fanfiction, his character could develop in terms of his emotional intelligence. He would learn to better express his love and care for his family members. For instance, he might become more patient with his sons' training, understanding that they need more guidance and support rather than just tough challenges. Also, he could become more protective of his family, having seen all the dangers out there in his adventures.
His character might become more adaptable. Naruto is used to Konoha, but in Kumo, he has to deal with new rules and a different social structure. This could make him more flexible in his thinking. For example, he might learn to approach problems in a more Kumo - like way.
On the other hand, forsaking Konoha could also make Naruto more empathetic towards those who are outsiders or outcasts. He has now experienced what it's like to be on the other side of Konoha's walls, so he might be more likely to help those who are in a similar situation. He could start to form his own group of allies who are also misfits, and together they could work towards a new kind of justice that is different from Konoha's.
His character might become more cautious. In the Naruto world, he's used to certain types of danger, but the real world has different and often more hidden threats. So he'll have to be more careful.
His power level would likely skyrocket. He'd gain Hashirama's wood - style abilities, which would make him a force to be reckoned with in battles.
Naruto's character would become more disciplined. Goku's strict training regime would instill a greater sense of self - control in Naruto. He'd be less impulsive in battles.
His character could become more instinct - driven. As a fox, he might be more in tune with his primal side, which could either make him more aggressive or more cautious depending on the situation. This would be a new aspect of his character development.
Naruto becomes more self - reliant. When he's out training on his own, he has to learn to make decisions without the help of others. He also gains a broader perspective as he meets different people during his travels. This exposure to new cultures and ways of thinking in fanfiction enriches his character. He starts to understand that there are many different paths to power and that he can learn from everyone. His ninja skills improve, of course, but his mental and emotional growth is just as significant.
His character might become more confident. Having the Juubi Eye gives him an edge that makes him believe more in his abilities.
When Naruto passes the Chunin Exam in fanfiction, his confidence would soar. He'd start to see himself as more of a capable ninja. He might become more of a leader among his peers, as passing the Chunin Exam is a sign of growth. For example, he could start giving advice to younger ninjas.
