He'd be more confident. In his original Genin days, he was a bit of an underdog, but with his future memories, he'd know his potential. So he'd act more boldly.
Naruto's character would likely become more mature. Since he has the memories of his future self, he would understand the consequences of his actions better. He would not be as impulsive when dealing with situations like fighting with Sasuke or facing the Akatsuki. Also, he would probably be more strategic in his approach to training and battles. Instead of just jumping into things head - first, he would plan and think ahead, making him a more well - rounded and respected ninja among his peers at a much earlier stage.
One possibility is that he would try to change the relationships around him. He might reach out to Sasuke earlier and prevent him from leaving the village. Also, he could be more strategic in dealing with the Akatsuki, since he'd know their plans in advance.
He might use his future knowledge to avoid some mistakes. For example, he could be more cautious with Orochimaru during the Chunin Exams. He might also try to train harder from the start to become even stronger faster.
Well, Naruto's character development can be quite different. In the normal story, he had to learn things the hard way through many battles and losses. But going back in time, he has the advantage of hindsight. He might become more of a mentor figure to his younger self. He could also be more confident in his abilities right from the start because he knows what he's capable of achieving in the future. He may also be more diplomatic in handling village politics as he's aware of the consequences of bad decisions from his own time. His relationships with his peers, like Sakura and Kakashi, could also change as he takes on a more proactive role in their interactions.
Naruto's values could change. For example, if he was adopted into a family that values peace above all else, he might strive to resolve conflicts in a more diplomatic way rather than through fighting. His ninja path could be more about preventing wars and building bridges between villages rather than just becoming the strongest shinobi.
Naruto's character could develop in a more humble way. After failing the test, he'd see that he has a long way to go. He might start to observe his classmates more closely, like how Sakura studies hard or how Sasuke is so focused during training. This could make him less impulsive and more strategic in his approach to becoming a ninja. He'd also learn the importance of preparation and might even seek help from unexpected sources, like some of the older ninjas in the village who have different techniques to teach.
Naruto would likely be more conflicted. Knowing he's related to Madara, who was a major antagonist, would make him question his own identity. He might be more secretive about this part of his heritage at first.
Well, Naruto would be more confident. Since he has the knowledge of the future, he knows what mistakes to avoid and how to handle situations better. For instance, he won't make the same naive mistakes when dealing with his enemies or friends.
His social skills might be underdeveloped at first. Since he was raised by wolves, he may not understand human social cues and norms easily. He could be more solitary and have trouble making friends in the beginning.
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.
