Naruto's view of his enemies would change. Hashirama was able to see the good in his opponents and find ways to coexist. Naruto would start to follow this example, trying to understand the motives of his enemies rather than just fighting them. He might even try to convert some of his foes into allies, just as Hashirama did with Madara in the past.
Naruto might become more in tune with nature. Since Hashirama was known for his strong connection to nature through his Wood Style, Naruto could develop a similar sense. This would not only affect his fighting style but also his overall view of the world around him.
He would likely become more powerful. With Uchiha and Senju blood, he could access new levels of chakra and skills. For example, he might be able to use the Susanoo more effectively than other Uchiha. His character might also become more complex, as he has to balance the different traits of the two clans.
His relationships with his peers would be different. For example, if he was adopted into a well - respected shinobi family, some characters who looked down on him before might treat him with more respect, and this would impact how he interacts with them. He might be less likely to seek attention through pranks.
Naruto's character might become more conflicted. His usual positive and straightforward view of the world could be challenged. He might start to question his own ninja way more often, as Pein's extreme methods would force him to re - evaluate his beliefs about how to achieve peace.
He might develop a more refined sense of strategy. Since the Nidaime was known for his intelligence and strategic thinking, Naruto could inherit some of that. He would be more calculated in his battles and less likely to rush in headfirst all the time.
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.
Naruto's character would develop a greater sense of responsibility. He would have to make tough decisions for the safety of the village and his team. His once - brash nature might be toned down as he realizes the importance of secrecy in ANBU operations. He would also gain more respect from the village as a whole, and this new - found respect could change how he views himself and his role in the ninja world.
If Naruto was born a girl, her character development would be really interesting. At first, she might be more self - conscious about her appearance and abilities compared to her male counterpart. But as she progresses, she would use this as motivation to become stronger. Her relationships with other characters would play a big role in her development. For instance, with Sakura, instead of a one - sided crush, they could develop a strong sister - like bond. And with Sasuke, their relationship could be more of a mutual respect and a push - and - pull dynamic based on their different genders and the expectations that come with it. This would lead to a Naruto who is more in touch with her emotions and uses them to her advantage in her ninja journey.
Naruto would likely be more brooding. With Madara as his father, he might inherit some of that Uchiha intensity. He'd probably be more cautious about making friends, knowing the Uchiha's history of being ostracized.
Naruto might develop a more ferocious side to his personality. Since Tsume is from a clan known for their wild and somewhat aggressive nature, Naruto could pick up some of those traits. He might be more direct in his approach to problems and less likely to hold back in a fight.
