His magical education would be different. Instead of learning about his parents through stories and a few mementos, he would have them as his teachers. They could give him one - on - one lessons in magic, which would make him a much more proficient wizard at a younger age. His understanding of the wizarding world's history and politics would also be shaped by his parents' views, which might be different from what he learned in the original story.
Harry's social life would be different too. He might not befriend Ron and Hermione in the same way. Since he would have a more confident upbringing, he could be part of a different social circle at Hogwarts. He could also be more involved in wizarding family events and have a larger network of wizarding friends and relatives, which would change the way he experiences Hogwarts and the wizarding world in general.
He would be more secure. In the original story, Harry grew up without his parents and was constantly seeking a sense of family. If raised by his parents, he would have that family bond from the start. He would likely be more outgoing and less introverted as he would have a stable home environment.
If Harry Potter was raised by his parents, he would have a very different personality. He would be more outgoing and less of a loner. His parents would have taught him all about the wizarding world from a young age, so he would be much more knowledgeable. Also, he might not have had the same kind of bond with Hagrid, as Hagrid's role in introducing him to the wizarding world would be diminished. In the fanfiction, we could see a more carefree Harry, not having to deal with the trauma of growing up an orphan.
If Harry had his parents, his emotional state would be more stable. Reading fanfiction would expose him to a variety of interpretations of his own story. Some might show him as an even greater hero, which could boost his confidence. Others might take a more comical approach, which could make him laugh.
He'd be more in touch with nature. His magic could be centered around life - based spells.
Naruto's social skills would also be different. Instead of being the lonely outcast, he would be part of a family. He would interact with other ninja kids in a more positive way. His parents could also guide him in making friends. He might be more diplomatic in his relationships because he has seen how his father, as the Hokage, dealt with people. This would all contribute to a very different Naruto compared to the one we know from the original series.
He'd be more technologically inclined. Since Wakanda is known for its advanced technology, Harry might integrate magic with tech more often. For instance, he could use Wakandan communication devices enhanced with magic for long - distance spells.
His life would be full of high - tech gadgets. Tony Stark is known for his advanced technology, so Harry would grow up surrounded by Iron Man - like tech. He might have a suit of his own at a young age, designed by Tony for protection.
If Harry was raised by his grandparents in fanfiction, his personality would change in several ways. For starters, he would be more self - assured because he'd grow up in a loving environment. He wouldn't have the same insecurities that came from being treated as an outcast at the Dursleys. He'd be more extroverted, as he wouldn't be afraid to show his true self. His sense of humor might be different too, perhaps more light - hearted and less sarcastic as a defense mechanism. He'd also have a stronger sense of family and heritage, which would influence his actions and decisions.
He might be more old - fashioned in his ways. His grandparents' values would likely have a big influence on him, so he could be more reserved and traditional compared to the Harry we know from the original series.
He might be more shrewd. Goblins are known for their business acumen and cunning. So, Harry could be more calculating in his decisions, not as impulsive as in the original story.
One possible plot could be that Harry grows up in a loving and magical home. He gets to learn magic from his parents at a very early age. His father, James, might teach him Quidditch skills right in their backyard. His mother, Lily, could pass on her knowledge of potions and herbology. They would also protect him from the dark forces that are still out there, perhaps leading to some epic battles where the family stands united against the remnants of Voldemort's followers.
