How could Naruto's character develop if sent to the future in fanfiction?

His sense of responsibility would grow even more. If he saw disasters or threats to his friends and village in the future, he would feel a stronger need to protect them. He might start to train others more rigorously so that they could all face future challenges together.

Naruto would become more determined. After seeing the future, he would be set on changing it for the better. For example, if he saw his friends die, he'd be more protective and strategic in his actions.

Naruto's character would likely develop in many ways. In the new world, he might face new challenges that test his beliefs. For example, if the new world has different ideas about power and justice, he would have to reevaluate his own views. He may also become more self - reliant as he doesn't have his usual friends and support system right away. His experiences in this new world could make him more empathetic towards different races and species, as he discovers new ways of living and interacting.

His character could become more adaptable. In a new universe, he'd have to quickly adjust to different rules and cultures. So, he might become more open - minded.

Issei could become more mature. He might be less impulsive and more strategic in his actions. For example, in battles, instead of just charging in, he would plan his attacks better.

Naruto's understanding of chakra control would improve. Controlling bugs with chakra requires a different kind of precision compared to his regular jutsu. This would make him a more well - rounded ninja, and he could use the skills he learns from bug control in other aspects of his fighting style, such as better controlling his Rasengan by applying the same fine - tuned chakra control.

Naruto could become more introspective. When exposed to the Book of Life, he might start to question his own life and the lives of those around him more deeply. His usual brashness could be tempered as he realizes the complexity of destiny. For example, if he sees the true pain and sacrifice behind some of his enemies' actions through the book, he may become more empathetic and try to find peaceful solutions rather than just fighting.

His character could become more mature. As a clan head, he has to think about the well - being of the whole clan, not just himself. This would force him to make tough decisions and grow in wisdom.

Naruto might become more empathetic. Loving a demon means seeing things from a different perspective. He would learn to understand the outcasts more, as the demon is likely an outcast in the ninja world. This would make him more inclusive in his actions towards others who are different.

By having Hashirama train Naruto, Naruto could learn patience. Hashirama, being from an older generation, would have a different pace of teaching and Naruto would need to adapt, thus growing in patience.
