Naruto could become more inclusive. If Sadaiam has a diverse and accepting culture, Naruto would start to see the value in different ways of life even more. He'd be more open to new ideas from all kinds of people, not just his ninja comrades. He might also start to focus more on the spiritual side of things, which could make him seem a bit more mysterious to his friends at first. He'd be delving deeper into the Sadaiam concepts that deal with the soul and inner peace, and this would show in his interactions.
He might become more serene. Since Sadaiam might have a calmer and more nature - centered philosophy, Naruto could adopt some of that. He'd be less impulsive in his actions and more contemplative.
Naruto would likely become more patient. Sadaiam's influence might teach him that things take time to develop, like the growth of plants or the evolution of a culture. He would no longer rush into situations as quickly. Instead, he'd take a moment to assess, much like how Sadaiam might approach their own affairs. This change in his personality would also affect his relationships. His friends would notice that he's not as hasty and is more willing to listen and understand before acting.
His personality could also become more calculating. Since the Sannin were known for their strategic thinking, Naruto would start to think several steps ahead. He might be more secretive about his plans too. He would no longer be the open - book Naruto. Instead, he would be like Jiraiya, who had his own secrets and plans. He would also show more patience, which is something he lacked before but the Sannin had in abundance when dealing with complex situations.
Perhaps Naruto meets a Sadaiam character who has a really kind heart and strong sense of justice, much like himself. This person shows Naruto the beauty of Sadaiam art, music, or philosophy. Naruto, being the open - minded person he is, gets immediately drawn to it. He might then start promoting Sadaiam values among his friends in Konoha, which could cause some interesting cultural exchanges and a few conflicts too as not everyone might be as receptive.
Naruto might become more aggressive at first. The influence of Venom could bring out his darker side. But as he gets used to it, he would learn to balance it with his usual positive and determined self.
Naruto might become more calm and collected. Goku has a certain simplicity and focus in his personality. Naruto could pick up on that and not be as impulsive as he usually is.
Naruto might become more reserved. Growing up under Zeltrech, he could be exposed to a more sophisticated and perhaps less rowdy environment compared to Konoha. So instead of his usual loud and brash self, he could develop a more calm and calculated side.
Well, first of all, Naruto's usually carefree and positive personality could be tempered with Ace's more complex emotional side. Ace had a lot of baggage related to his family and his identity as a pirate. So Naruto might start to have some internal struggles about his place in the world. He could become more reserved in some ways, like not being as quick to share his feelings. At the same time, his loyalty would become even more intense. He would be willing to go to greater lengths for his friends and the village, almost to the point of self - sacrifice, which was a big part of Ace's character. And his view of power might change too. Instead of just seeing it as a means to protect and be recognized, he could see it as a way to uphold a certain code, like Ace's code among the pirates.
Naruto's normally bright and positive personality might become more conflicted. Since Douma has a more complex and often morally ambiguous nature, Naruto would have to grapple with new emotions. He might become more reserved as he tries to figure out how to handle Douma's powers without losing his own identity.
He might be more calm. Since the female Kurama could be a stable influence, Naruto wouldn't be as impulsive.
Naruto might become a bit more reserved. Since Ulquiorra is a rather cold and stoic character, Naruto could start to hold back his more exuberant emotions. He might also become more analytical, like Ulquiorra, when it comes to combat situations. Instead of charging in head - first all the time, he'd think more about the best approach.
Naruto's always been this energetic and positive guy. But if he becomes Caius Ballad, he might become more brooding. Caius Ballad has a different kind of vibe, more serious and intense. Naruto's cheerfulness might be toned down a bit, and he could become more focused on achieving specific goals rather than just his general idea of becoming Hokage.
