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.
His confidence usually skyrockets. Knowing he has this new inheritance gives him a sense of purpose and power. He may become more assertive in his actions and decisions.
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.
After getting shot, Sam could develop a new sense of purpose. Maybe he was shot while trying to protect someone or something. This could fuel his determination to fight for the greater good. He might also start to question his own mortality more deeply. This self - reflection could lead to changes in his relationships. He could become closer to Dean as they both face the reality of their dangerous lives. Or he might seek out new allies who can help him in his fight, perhaps other hunters or even some supernatural beings who are on their side.
She could become more cautious. After getting hurt, Felicity might be more aware of the risks she takes. For instance, she may double - check security measures before diving into dangerous cyber - investigations.
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.
After marriage, their relationship would grow even stronger. They would support each other in their respective roles. Naruto as the Hokage (assuming he is) would have Kushina by his side, giving him advice. And Kushina would be involved in village matters too, using her Uzumaki knowledge. They would also start a family, and Naruto would be a loving and doting father, just like he always wanted to be.
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 awakening the Sharingan, Naruto may become more perceptive. He starts to notice small details in his surroundings and in people's behavior that he missed before. This helps him in his ninja missions as he can plan better strategies. His confidence also grows as he realizes he has a new and powerful tool at his disposal.
When Naruto absorbs the Shinju in fanfiction, his character development can take many forms. He could become more isolated as others may fear his new power. But at the same time, he might also strive to prove that he's still the same Naruto at heart. He may start to explore the deeper meaning of his power and how it can be used for good, which would lead to a more mature and introspective side of his character.
Naruto's character might become more empathetic. After the fight, he has seen Sasuke's pain up close. So he could be more understanding of others' struggles. For example, when dealing with other rogue ninjas, he may try to find the root cause of their problems instead of just fighting them.
