If Naruto keeps the Forbidden Scroll in fanfiction, his character may become more self - reliant. He has this powerful resource that he's not supposed to have, so he can't rely on his usual mentors and teachers. He has to figure things out on his own, which could lead to him growing up faster in some ways. He might also become a bit more solitary as he tries to keep his secret. But at the same time, it could also make him more determined to protect the village from any threats that might come as a result of his possession of the scroll.
In fanfiction, if Naruto keeps the Forbidden Scroll, his character development could be complex. Initially, he might be excited by the power it potentially holds. But as he delves deeper, he could realize the great responsibility that comes with it. This could lead to a more mature Naruto. He may start to question the village's rules and traditions regarding the scroll. He might also face internal moral dilemmas, like whether it's right to use the forbidden jutsu in the scroll, especially if it means sacrificing some of his values. All these experiences would shape his character in a way that is different from the original Naruto storyline.
Naruto may become more independent. He realizes that he has knowledge that others don't, and he has to rely on himself to figure out how to use it properly without getting into too much trouble. He might start to train more on his own and explore new ways to incorporate what he learned into his fighting style. In some fanfictions, this could lead to him developing new and unique jutsu combinations that set him apart from other ninjas. This also makes him more of a wildcard in battles, as opponents won't be able to predict his moves as easily.
In some fanfictions, if Naruto keeps the Forbidden Scroll, he might discover powerful and forbidden jutsu within it. This could lead to him quickly becoming much stronger than his peers. He might learn some dark or extremely dangerous techniques that could change the course of his battles and relationships in the ninja world.
His confidence usually skyrockets. Since he has access to powerful techniques from the Forbidden Scroll, he feels more capable in combat and in dealing with difficult situations. For example, if he learns a powerful healing jutsu, he might be more willing to take risks in battles knowing he can heal himself or others quickly.
In some fanfiction, Naruto could use his shadow clone jutsu to create a distraction. While the clones are causing chaos, he slips into the room with the Forbidden Scroll and begins the copying process. He might also have some help from an unexpected ally who knows the security system around the scroll and helps him get access.
His character would develop in a more complex way. He'd have to grapple with the new power and the responsibility that comes with it. He might become more isolated at first as others fear his power. But then he'd learn to use it for good and become more confident in his abilities.
His character might become more cautious. Since he already knows what the future holds, he would be more careful in his actions to avoid making the same mistakes. For example, he might not be as impulsive when facing enemies.
If Naruto becomes the Kyuubi in fanfiction, his character development would be multi - faceted. Firstly, he'd have to learn self - control like never before. The Kyuubi's power is so strong that it could easily overtake him. He would constantly be in a battle within himself to keep his humanity intact. His view of the ninja world would shift. He might start to see the importance of balance between different forces more clearly. In terms of his relationships, he'd have to re - earn the trust of some, while others would be drawn to his new power. Overall, his journey would be one of self - discovery and mastering this new, powerful identity.
It could also lead to him being targeted by enemies. If word gets out that he has access to the Forbidden Scroll's secrets, villains might come after him to either steal the knowledge from him or stop him from using it. This would put him in a lot of dangerous situations and force him to grow up quickly in order to protect himself and the village.
Naruto may become more stealthy and less impulsive. Working in ANBU, he has to be quiet and calculating. He might learn new jutsu and fighting styles that are more suitable for covert operations.
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.
