He would become more empathetic. As a single father, Naruto would have to understand his child's feelings more deeply. He'd be quicker to pick up on when the child is sad or happy, and adjust his parenting accordingly. For example, if his child is sad about not having a mother, Naruto would have to be extra sensitive.
Naruto would likely become more diplomatic. As an emperor, he can't just rely on brute force like he sometimes did as a ninja. He'd have to think about the long - term consequences of his actions for the whole empire. So, he'd develop better negotiation skills.
His character would become more complex. Naruto is known for his positive and determined attitude. But as Riser, he might have a more egotistical side. He could start to show off his new powers more and be less concerned about the feelings of others at times.
Naruto would likely become more bitter at first. Without the family support he should have had, he might be more distrustful of others. But as he grows, he could use this as motivation to become stronger. For example, he might train twice as hard as in the original story.
He'd likely be more bitter. Naruto in the original is so positive despite his hardships. But with motherly neglect, he could be cynical. He might not trust people as easily and could be more guarded.
Naruto's confidence would likely be different. Instead of the somewhat brash confidence that came from constantly proving himself in the original story, he would have a more serene and assured confidence, based on Hagoromo's teachings. His understanding of the world would be more profound from the start. He wouldn't view enemies as simply 'bad guys' but rather as products of a flawed system. His sense of justice would be more complex and far - reaching. He would strive for a more global peace rather than just the protection of his village. Also, his relationship with Sasuke would be less about rivalry and more about shared understanding. They would both be on a path towards a greater good, and Naruto would be more able to communicate his ideas to Sasuke, preventing some of the rifts that occurred in the original story.
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 would be more self - assured. In the original, he was always seeking approval because he was an orphan. With his parents alive, he'd have that unconditional love and support, so he wouldn't be as desperate for others' recognition.
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.
Naruto would likely become more independent. Without his parents' attention, he would have to fend for himself more. He might grow up quicker and be more self - reliant. For example, he would have to learn to cook and clean for himself at a much younger age.
Naruto might become more stealthy and calculating. Mikoto, being an Uchiha, could teach him the art of patience and precision in combat, which would be a contrast to his usual brash and head - on fighting style.
