If Naruto got Wolverine's power in fanfiction, his development would be really interesting. He'd have to learn to control the healing factor and not rely too much on it. His sense of self - worth might change as he realizes he has this new, extremely powerful ability. He might also become more of a loner in some ways, but still be part of the Konoha community. He could start to question his ninja way in the face of this new power, but ultimately find a way to incorporate it into his values.
His character might become more confident, almost to the point of being cocky. He would know that he can handle any situation, so he might take more risks.
His character development could become more complex. He may start to question his own identity and purpose. Since chaos is an unpredictable force, he has to constantly adapt and learn how to use it without causing too much harm.
Naruto may become more confident. Having Star Platinum gives him a powerful new tool, so he'll be less likely to doubt himself in battles.
His character could become more complex. As a homunculus, Naruto might struggle with the new moral implications of his existence. He was always a positive and determined ninja, but now he may have to face the darker side of his new form.
His character would become more confident. The power of the Flash would make him realize his potential even more. He'd be less likely to doubt himself in tough situations.
Naruto's character could become more complex. He'd have to deal with the moral implications of using Jiongu. Since Jiongu has some rather strange and powerful abilities, Naruto would need to ensure he doesn't misuse it. This would add depth to his character as he'd be constantly making decisions about when and how to use this new power.
Naruto's character could develop morally if he finds Mjolnir. Since Mjolnir is only liftable by those who are worthy, it would reinforce Naruto's sense of justice. He'd see himself as even more of a protector. He might start to view his ninja way in a new light, perhaps incorporating some of the values associated with Mjolnir. For example, he could become more strict about who is worthy of his protection, like Thor is with Mjolnir.
His character would become more cerebral. Instead of relying solely on his physical strength and ninjutsu, he'd use his intellect. He might become more patient as scientific research requires time.
If Naruto joins Iwa in fanfiction, his character development could be significant. He'd have to deal with being an outsider at first. This would test his resolve and make him grow in patience. He may also start to see the world from a different perspective, as Iwa's goals and values might be different from Konoha's. This could lead to him becoming more diplomatic and understanding of different ninja cultures.
Well, if Naruto had Wolverine's powers, his fighting style would be drastically different. He could use those adamantium claws in close combat, making him even more formidable in one - on - one battles. His healing factor would also be a game - changer. He could recover from injuries much faster, allowing him to keep fighting without having to rest as much. This might make him more reckless in battle, knowing he can heal quickly. Also, it could change his relationships with his friends and enemies. His enemies might be more afraid of him, and his friends might rely on him even more in dangerous situations.
