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.
Harry's personality would likely be a blend of his original traits and Wolverine's. He'd be more solitary at times, like Wolverine. But also, he'd still have that underlying sense of justice from his own story. He might be more cynical too, due to Wolverine's jaded view of the world. He would probably be quicker to act and less patient with bureaucracy or rules that don't seem to make sense.
Harry's sense of humor might be different. Instead of the quick - witted and sometimes sarcastic humor he had in the original story, he could have a drier, more understated sense of humor. Snape's own rather caustic personality could influence Harry to be more subtle in his jokes and remarks, and perhaps a bit more cynical at times.
If raised by Hecate, Harry would likely be more self - assured in his magical abilities from an early age. Hecate's teaching methods might instill in him a deep sense of pride in his magic. He could also be more aloof, as he would be used to a different kind of magical society under Hecate's influence. His values would be shaped by Hecate's ancient wisdom, so he might be more focused on the bigger picture of magic in the universe rather than just the wizarding world's problems.
He might be more hardened. Westeros is a tough place, so he could be less naive than in the original story.
He would likely be more aggressive. Demons are often associated with aggression, so Harry might not be as patient or kind - hearted as in the original story.
Harry's personality would be much different. Mileena is a complex and often brutal character. Harry, under her care, would likely be less trusting and more self - reliant. He might not be as open - hearted as the original Harry. His sense of humor could also be darker, influenced by Mileena's world where there is a lot of death and struggle.
His personality would be much more bold and fearless. Deadpool's influence would make Harry less afraid of taking risks and more willing to jump into dangerous situations without hesitation. He would also be more adaptable as he would have grown up in a constantly changing and chaotic environment created by Deadpool.
He'd be more aggressive. Gangs often have a tough and sometimes violent culture, so Harry might be quicker to anger and use force.
He would probably be more in tune with nature. Since animals operate on instinct a lot, he might have a stronger sense of intuition. For example, if he was raised by deer, he'd be more skittish and aware of his surroundings, always on the lookout for danger like they are.
