His character development could involve him becoming more strategic. Since Hanzo was known for his cunning and strategic mind, Naruto might inherit some of that. He could start to think more about long - term plans and how to outwit his opponents. Also, Naruto's sense of justice might be influenced. Hanzo had his own way of dealing with things, and Naruto would have to decide which parts of Hanzo's approach to justice he wants to incorporate into his own. He might become more diplomatic in some situations, trying to find solutions that avoid unnecessary bloodshed like Hanzo sometimes did.
Naruto's development could also include a new sense of responsibility. Knowing that he is related to Hanzo, a powerful and well - known figure, he might feel more pressure to live up to a certain standard. This could make him train harder and strive to be a better shinobi not just for himself and Konoha, but also to honor his new - found family connection. He could also develop a more solemn side to his personality, especially when dealing with matters related to Hanzo's past or the legacy he has inherited.
Naruto's chakra control and combat skills would develop differently. Hanzo was a master of his own unique techniques. Naruto would be trained in those, and perhaps develop his own spin on them. His fighting style might be more stealth - based and less reliant on brute force like his Rasengan - centric style in the original. He would also have a different sense of honor, influenced by Hanzo's code of conduct.
Yes, there might be such fanfictions out there. Fanfiction writers often come up with creative and unexpected relationships between characters. They like to explore different 'what - if' scenarios. So, it's not surprising that someone could write a story where Naruto has a relation to Hanzo as his grandson.
Naruto would likely become more studious about the history of the village. Since Tobirama was a key figure in building Konoha, Naruto would want to know more about his great - grandfather's vision. This would make him more of a thinker, not just relying on his brute strength. He might also become more diplomatic, as Tobirama was known for his political acumen.
Naruto would likely be more conflicted. He has always been an outcast in the village, but now with his relation to Madara, he would be even more of an enigma to the villagers. His character might become more brooding as he tries to understand his place in the world. He would still have his goal of becoming Hokage, but it would be colored by his new heritage. He might have to prove himself even more, not just to the village but also to himself that he's not like Madara in terms of causing chaos.
His view of the ninja world could shift. Hanzo had a complex relationship with different ninja villages. If Naruto is influenced by Hanzo, he may start to question the existing power dynamics in the ninja world more deeply. He could become more involved in diplomatic affairs and try to find solutions that are more in line with Hanzo's approach of maintaining a balance of power, which would be a significant change from his more straightforward 'friendship - first' ideology.
His approach to problems would be different. Naruto usually rushes into things head - on. But as Tsunade's grandson, he could be more strategic. Tsunade is a smart leader and a skilled ninja. Naruto could learn from her how to analyze situations better. Also, his relationship with Sasuke would be affected. He might be more of a guiding figure to Sasuke, rather than just a rival, as he would have a stronger sense of responsibility from his family connection.
Naruto might become more introspective. Knowing he has a connection to Mu could make him question his own identity more deeply. He may start to act more like Mu in some ways, perhaps becoming more calculating in battle instead of his usual head - on approach.
One possible plot could be that Naruto discovers his relation to Hanzo later in his life. This new knowledge makes him question his place in the ninja world and his own identity. He might then try to learn more about Hanzo's past and the secrets that come with being related to him.
His character could develop a more solitary nature. Without the support system of Team 7, Naruto might become more self - reliant and withdrawn. He would have to figure out things on his own more often.
His character development could involve him becoming more empathetic. Being mute, he would understand the struggles of those who are different or marginalized. He might start to advocate for them in his own silent way. Also, he'd have to work hard on his physical expressions and body language, which could lead to a more refined and nuanced way of presenting himself. His relationships with others would also change, making him more reliant on true friendship and loyalty rather than just words.
