Naruto's character could develop a darker side. The Uchiha have a history of tragedy and darkness, and being the son of an Uchiha, he might be more affected by it. He could struggle with the same inner demons that the Uchiha often face, such as the thirst for power and revenge, but ultimately overcome them in a way that shows his growth and strength as a character.
Naruto might be more in tune with the Uchiha's sense of pride and honor. He could be less boisterous and more calculating in his actions, as the Uchiha are known for their intelligence. For example, instead of rushing into battles head - on all the time, he would think things through more carefully.
His development could also involve a deeper understanding of the Sharingan. Since his mother is an Uchiha, he might have a natural affinity for it. He could learn to master it faster and use it in ways that are unique to him. This could lead to new jutsu combinations that blend Uzumaki and Uchiha techniques.
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.
He might be more self - assured from the start. Knowing he's the son of Indra could give him a sense of purpose and confidence. His relationships with Sasuke would also be different. Instead of just a rivalry, there could be a deeper understanding due to their shared connection to the Indra - Asura lineage.
He might be more confident from the start. Knowing he is related to such a powerful figure like Mito Uzumaki could give him a sense of pride and purpose early on. His development might focus more on mastering the Uzumaki clan's techniques rather than just trying to be recognized in the village.
Naruto would likely be more in tune with his emotions. Since the Fem Kyuubi could potentially have a more nurturing influence, he might not be as brash and loud as in the original story. He could be more introspective and have a deeper understanding of the power he holds from a young age. This would change his interactions with his peers, as he would seem more mature in some ways.
Naruto's development could be marked by a new sense of responsibility. Instead of just aiming to become Hokage for the sake of being recognized in the ninja world, he would now have a greater purpose of living up to his divine heritage. His actions would be guided not only by his ninja values but also by the values associated with being the son of Female Arceus. This could lead to him making different choices in his relationships, battles, and his overall journey. He might be more diplomatic in dealing with enemies as he realizes the impact his actions could have on a much larger scale, both in the ninja world and the divine realm.
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.
It could start as a friendship. Naruto, being his friendly self, would approach Hitomi first. They might bond over their shared love for their village or a common goal like protecting the weak. As time passes, they might start to rely on each other more and more, and this could gradually turn into a deeper relationship, like a romantic one.
If Naruto joins the Uchiha clan, his character would develop in several ways. He would have to adapt to the clan's hierarchical structure. This could make him more respectful of traditions. His relationship with Sasuke would take on a whole new dimension. They could become more like brothers within the clan, and Naruto would have a stronger sense of family. Also, his understanding of power and responsibility would grow as he learns about the Uchiha's power - hungry past and how it led to their downfall.
