Well, Harry Potter is known for his quiet determination and often brooding nature, especially when it comes to his past traumas. But if he were reborn as Naruto, he would be much more exuberant. Naruto is always shouting his goals and dreams from the rooftops. Harry would start to do the same. His sense of humor would also change. While Harry had a dry, sarcastic sense of humor at times, Naruto's humor is more slapstick and boisterous. So Harry would likely become more prone to making jokes in a louder, more physical way. And his leadership style would shift too. Instead of leading through example and quiet wisdom like in Hogwarts, he would lead with the same kind of rambunctious energy that Naruto does in Konoha.
If reborn as Naruto, Harry's personality would change in several ways. Harry was often burdened with the weight of his past and his destiny in the wizarding world. But as Naruto, he could be more carefree. Naruto's positive attitude towards life and his ability to see the good in people would influence Harry. He would become more of an optimist, always looking for the best in every situation. Also, Naruto's love for his village and his determination to protect it would strengthen Harry's already existing sense of loyalty. However, he would still retain some of his cautious nature from his days as a wizard, which could make for an interesting mix of boldness and prudence.
His personality could be influenced by the Dornish sense of justice which is often more direct. In his previous life, Harry had to deal with a lot of bureaucracy in the wizarding world. In Dorne, he might be more inclined to take matters into his own hands when it comes to righting wrongs. Also, the Dornish love for music and art could make him more creative and expressive. He may not be as shy about showing off his magic skills as he was in Hogwarts. Instead, he could use his magic in more artistic and flamboyant ways to impress others and make a statement.
His personality would probably be more aloof. Since basilisks are solitary creatures, Harry might not be as sociable as in the original story.
He might become more outgoing. In the Naruto world, the culture is different from the rather formal and often secluded wizarding world. Harry would be exposed to a more boisterous and open - minded society, so he could become more extroverted and less reserved.
Harry would likely be more fearless and brash. Kenpachi is a bold and fearless fighter, and his influence would make Harry less hesitant. For example, when facing a bully like Draco, Harry might immediately react with physical force rather than just trading barbs. He would be more upfront and direct in his approach to problems.
He might be more reserved. The Malfoy upbringing would likely make him less impulsive compared to his canon self. He could also be more calculating in his actions.
If Harry Potter was raised by Luffy, his personality would change significantly. Luffy is always cheerful and optimistic, and this would seep into Harry. Harry would be less haunted by his past and more focused on the present and future. His sense of humor would also be different. Luffy has a very simple and direct sense of humor, and Harry would probably adopt some of that. He would be more likely to laugh at the simple things in life. In addition, Harry would be more impulsive. Luffy often acts on impulse, and Harry would be more likely to do the same, which could lead to both great adventures and some trouble. His loyalty would also be more like Luffy's, fierce and unwavering towards his friends.
He'd probably be more in tune with nature. Since mermaids live in harmony with the sea, Harry might have a deep respect for all living things. He could be more calm and collected, like the stillness of the ocean depths.
Harry's bravery, which was one of his most prominent traits, would be very useful in the often - dangerous world of Westeros. He might be more willing to take risks than the average Targaryen. His kindness too would play a role. He could be the one to show mercy in a world where mercy is sometimes seen as a weakness. He would probably adapt his Hogwarts - learned values to fit the different cultural context of Westeros.
Harry would likely be more confident in his pure - blood status, at least on the surface. Since he's raised by the Malfoys' twins, he'd be exposed to the pure - blood elitist culture from a young age. He might be more calculating and less impulsive than in the original story, having learned from the Malfoy family's shrewd ways.
His personality would be significantly different. Since house - elves have a very different culture from wizards, Harry would grow up with different values. He could be more empathetic towards the underprivileged in the wizarding world, like the house - elves themselves. He might also be less concerned with the pure - blood/muggle - born divide, as house - elves don't really care about such things. Additionally, he would have a strong sense of duty towards those he considers family, which in this case would be the house - elf that raised him. This sense of family and loyalty would be a core part of his personality.
