Well, Naruto's view of the world could be much more cynical. Koharu has seen a lot of the darker side of the ninja world in her long life. Growing up under her, Naruto would be exposed to her jaded perspective. He might be less trusting of others outside of the village and more focused on self - preservation and the village's interests in a more calculating way. For instance, instead of believing in the good in everyone right away, he would be more skeptical and analyze people's motives more closely.
Naruto might develop a stronger sense of propriety. Since Koharu is an elder and values the old - fashioned ways, Naruto would likely grow up with a greater respect for protocol. This could make him seem more formal and less likely to pull pranks or act impulsively.
Naruto's personality would likely be more disciplined. ANBU are highly disciplined soldiers. So, he would be less likely to act impulsively. Instead of jumping into situations without thinking, he would analyze first. However, he might also lack some of the warmth that comes from his normal upbringing. He might have a harder time making friends because he's been raised in a more austere environment. For example, he might not be as quick to forgive as he was in the original story, as the ANBU way is more about justice and less about second chances.
Naruto's personality would develop in a more complex way. With Kurenai as a mother figure, he'd be more empathetic and in tune with others' emotions. Anko would add a bit of rebelliousness to his character. He'd still be determined like in the original story, but his way of achieving his goals would be more refined. He might be more secretive too, as he'd learn from Anko that not everything needs to be out in the open all the time.
Naruto's personality would likely be more calm and composed. Hashirama was known for his level - headedness. So, Naruto might not be as brash as he was in the original story. He would probably think things through more carefully before acting.
His personality could be more open - minded. Since he's exposed to an alien culture from a young age, he might not have the same prejudices as other ninjas. He'd be more curious about different beings and ideas.
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.
Since McGonagall has a strong sense of justice, Harry would probably have an even more acute sense of right and wrong. He would grow up with her values of fairness and loyalty deeply ingrained. This could lead to him being more proactive in standing up for others who are being wronged, not just because of his own experiences, but because of the values he was taught by McGonagall.
He might be more refined. The Delacour family seems to have a certain elegance about them. Harry could be more sophisticated in his speech and mannerisms. He may also be more confident in social situations as he would have grown up in a family used to high - society magical events.
Harry would probably be more rebellious. Remus and Sirius are not exactly the rule - following types. They've both had run - ins with the law in the wizarding world. So Harry would grow up seeing that sometimes breaking the rules is necessary for doing what's right. He might be less hesitant to take matters into his own hands.
Well, in Iwa, Naruto would grow up in a more competitive and perhaps harsher environment. This could lead to his personality being more tenacious. He would have to fight harder for recognition. His optimism might be tinged with a bit more realism. He'd still be the Naruto we know with his kind heart, but his experiences in Iwa would shape it differently. For example, he might be quicker to defend Iwa's interests over others due to his upbringing there. His friendships would also be different. He'd form bonds based on mutual respect in a more cut - throat environment, which could make his relationships deeper and more guarded at the same time.
Naruto might be more refined. Growing up in the daimyo's court, he would be exposed to different etiquettes and cultures. He could be more diplomatic compared to his original brash self.
