Harry's character would develop with a stronger sense of family pride. He'd be part of the Potter family in a different way than before. He would grow up with a different set of values, influenced by James and his parents. He could be more adventurous, knowing that he has a support system. Also, his understanding of the wizarding world would be more in - depth from the start. He might not be as naive as he was in his original life when it comes to the darker aspects of the wizarding world, because he already has the knowledge of what can go wrong.
He might be more confident from the start. In his past life, Harry grew up without his parents and had a difficult childhood. But as James' brother, he would grow up in a loving family environment. This could make him more outgoing and less hesitant in social situations.
He'd be more cunning. In Gryffindor, Harry was brave and impulsive. In Slytherin, he'd learn to think before acting. He might also become more ambitious, not just about defeating Voldemort, but about changing the reputation of Slytherin.
If Harry was born a Weasley, his character would be much more carefree in his early years. The Weasley family's relatively poor but happy - go - lucky lifestyle would rub off on him. He wouldn't have the same sense of burden that the real Harry had, at least not in the same way. Instead of constantly thinking about his parents' death and his role in the wizarding world, he'd be more focused on the day - to - day joys and challenges within the Weasley family. For example, he'd be excited about things like helping with the family's garden gnome problem or getting ready for the next Quidditch match. However, as he got older and learned about his true identity, he'd have to reconcile his Weasley - influenced self with the 'Boy Who Lived' status, which could lead to some complex character development.
He might be more strategic. Tobirama was a very strategic thinker, so Naruto could inherit that trait. Instead of just charging into battles, he'd plan more carefully.
Harry's character would develop in a more patient and self - assured way. Merlin's long - lived experience and his different approach to magic would shape Harry. Instead of the somewhat isolated and often confused boy in the original story, he would be more open - minded. He would be exposed to different magical cultures and ideas from Merlin, which would make him a more well - rounded wizard. He would also be more in tune with the ancient and hidden parts of magic, and this would give him a different kind of power and presence.
She might be more in touch with her emotions. As a girl, Naruto could be more likely to show vulnerability, which was something she hid as a boy. This could lead to deeper relationships with her friends as they see a different side of her.
He might be more confident. Since his grandfather has more life experience, he could instill in Harry a sense of self - assurance from an early age.
If Harry was raised by his mother, his understanding of magic would be different. His mother could pass on her own unique magical knowledge and skills to him. He might be more proficient in certain areas of magic earlier on. Also, his view of the wizarding world would be more positive as he grows up in a nurturing magical environment, rather than the hostile one at the Dursleys'. This would likely make him a more confident and less brooding character, and his decisions might be more based on hope and love rather than revenge or survival.
He would be more confident. Without the trauma of losing his parents, Harry would not have that underlying sense of insecurity. He would probably be more outgoing and less hesitant in making friends and taking risks.
If Draco was sorted into Ravenclaw, his character would develop in a very different way. His sense of self - worth would no longer be tied so much to his family name and pure - blood status. He'd have to rely on his intelligence and wits. He might become more empathetic as he's exposed to different types of students in Ravenclaw. He could start to question the bigotry he was taught at home and become a more open - minded wizard. Also, his rivalry with Harry Potter could take a different turn. Instead of being a pure - blood supremacist - driven rivalry, it could be more about academic competition or different views on how to use magic for the greater good.
