His personality would likely be more introverted. Itachi was a rather quiet and introspective person, and this trait would rub off on Harry. Harry would probably be more cautious in his actions and less impulsive.
If raised by Itachi, Harry would develop a very different personality. He would be more in tune with his emotions and able to control them better. Itachi was very good at hiding his true feelings, and Harry would learn this skill. This would make him seem more mysterious to his peers. Also, he would have a more global view of things, not just limited to the wizarding world, because Itachi had a broader perspective on different worlds and cultures in the Naruto universe. His personality would be a unique blend of the kind - heartedness he had originally and the stoicism and wisdom of Itachi.
His personality would be more noble. Aslan is a symbol of nobility and righteousness. Harry would likely inherit those traits, being more selfless and having a stronger sense of justice. He'd be more like a natural leader.
If raised by Xander, Harry would be more street - wise. Xander has had to fend for himself in a tough world. Harry would pick up on that. He would be less naive about the world around him. His sense of right and wrong would also be influenced. Xander has a moral code that is a bit more flexible than the strict wizarding world's. Harry might be more willing to break the rules if it means doing the right thing in a more complex situation. For example, he might be more likely to help a dark wizard who has been wrongly accused, rather than just following the Ministry's orders blindly.
Harry's personality would develop in a very different way. Growing up with Sirius and Remus, he'd be constantly surrounded by tales of the Marauders. This would make him more mischievous in a good way. He'd have a better understanding of the grey areas in life, as Sirius has a bit of a wild side and Remus has his own struggles. Harry would also be more independent, as Sirius and Remus would encourage him to think for himself and not blindly follow rules. He'd be more likely to question authority, especially when it seems unjust. And his sense of humor would be more developed, as Sirius is known for his jokes and pranks. Overall, he'd be a more well - rounded and confident young wizard.
His personality would likely be very guarded. Growing up in Azkaban, he'd have to be constantly on edge. He'd be less likely to trust others easily and more likely to keep his emotions bottled up. He might be a bit of a loner, used to fending for himself.
Harry would likely be more confident. With Sirius as his sole guardian in France, he'd be away from the Dursleys' abuse. Sirius would encourage Harry to be bold and fearless, and without the constant pressure of the British wizarding community's expectations, Harry could be more laid - back and easy - going.
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.
His personality would likely be more cold and calculating. He'd be used to getting his way through underhanded means taught by the villains.
His personality would probably be more aloof. Since basilisks are solitary creatures, Harry might not be as sociable as in the original story.
Harry's personality might be more in tune with nature and spiritual values. He could be more calm and centered compared to the canon Harry. Since Kami often represents purity and goodness, Harry may be more trusting and less cynical.
