He might be more hardened. Westeros is a tough place, so he could be less naive than in the original story.
His personality would likely be a blend of his Gryffindor traits and the influence of Westeros. He would still be brave, but he might also be more cynical. In Westeros, he would see a lot of backstabbing and political games. This could make him more guarded and less trusting. He might also be more adaptable as he has to fit into a different kind of society. Instead of the relatively sheltered life at Hogwarts, he would be exposed to the harsher realities of Westeros, which could make him more street - smart and less idealistic.
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 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.
His personality would likely be more in tune with nature. He'd be more patient, like how animals in the jungle wait for the right moment to hunt or find food. He'd also be more adaptable, having to deal with the constantly changing jungle environment. And he might be more of an outsider in the wizarding world, not fully understanding their ways at first because of his jungle - raised mindset.
He'd be more reserved. Hel's influence would make him less likely to trust easily. He wouldn't have the same sunny disposition as he might have had if raised by the Dursleys and then influenced by Hogwarts. He'd be more attuned to the darker aspects of magic and life in general.
He'd be more laid - back. Island life is slow - paced, so he might not be as impatient as the regular Harry. He'd also be more in tune with nature, having a calmness about him that comes from living close to the sea and the land.
