His confidence might increase. Knowing that he's considered a threat in the Bingo Book could make Naruto feel more powerful. He might start to believe more in his own abilities and be more assertive in battles.
Naruto could develop a darker side in some fanfictions. The constant threat of being hunted could make him more cynical or distrustful at first. However, as he overcomes these challenges, he could also become more empathetic towards those who are also hunted or outcast in the ninja world. This could lead to him trying to reform the system that created the Bingo Book in the first place.
Naruto's sense of responsibility would likely grow. Since his actions now draw more attention and can have greater consequences, he'd be more careful about what he does. He'd also be more aware of how his actions affect his friends and the village. For example, he might be more cautious about going on solo missions as he doesn't want to put himself in unnecessary danger that could also endanger others. He could also become more diplomatic, trying to negotiate with some of his pursuers rather than always fighting head - on.
Naruto could also become more empathetic. Since he has experienced being silenced, he might be more sensitive to others who are in similar situations. He may start to stand up for those who are muted or oppressed in the fanfiction world, thus growing as a character in terms of his social justice values.
In some fanfictions, Naruto getting in the Bingo Book could lead to a change in his relationships. His friends might be more worried about him and try to protect him even more. For example, Sasuke could become more determined to keep Naruto safe from those who would harm him because of his new status in the Bingo Book. Also, the village might have to take extra precautions to keep Naruto hidden or use him as a sort of decoy in strategic battles.
Aizawa's character might develop in a more complex way. For instance, if the quirk makes him experience something traumatic, he could become more protective of his students. He might also start to question his own abilities and role as a hero. Maybe he realizes that he needs to rely more on others and not just his own quirk. This could lead to him forming stronger bonds with his fellow heroes and being more open to teamwork.
Draco could become more independent. Before getting his wand, he was probably more reliant on his family's name and status. But with his wand, he has his own tool to make things happen. For instance, he might start to explore parts of the wizarding world that his family doesn't control or influence. He could start to form his own opinions about magic, rather than just following what his father says. He might even start to see the value in Muggle - born magic, which would be a huge shift in his character.
After absorbing Kami in fanfiction, Naruto's character development can be quite complex. He could start to question his own identity and what it means to have such power. This internal conflict can lead to him becoming more empathetic towards others who are also dealing with power or identity issues. He may also become more cautious in using his new abilities, as he realizes the potential consequences of misusing the power of Kami.
Naruto being in the Bingo Book means his freedom is restricted. He can't move around as freely as before. He has to be cautious of every new face he meets because anyone could be a bounty hunter. Also, his relationships with the villages might become strained as they are now hunting him, even if he is innocent.
Well, Naruto has always been a bit of a goof - off, but after graduation in this fanfiction, he could see that the world is more dangerous than he thought. He may start to study more about different jutsus and how to counter enemies. His relationships with his friends might also change as he gets more serious. For example, he might push them to train harder too, leading to some conflicts at first but ultimately making their bonds stronger.
His character may become more withdrawn at first. Losing Jiraiya, who was like a father figure to him, could make Naruto less open and more focused on his internal pain.
Naruto might become more introspective. He has always been action - oriented, but losing his arm could force him to think more about his actions and their consequences. For example, he may be more cautious when engaging in battles.
Naruto may also gain a deeper understanding of Kakashi's own struggles. As he recovers from the hurt, he could start to realize that Kakashi might have had his reasons, whether it was to protect Naruto in a strange way or because of Kakashi's own internal conflicts. This new understanding could lead to a more complex and mature relationship between them.
