He'd likely be more withdrawn and edgy. Constant exposure to the creepy elements would make him less trusting and more on - guard all the time.
Harry Potter's personality would be drastically different. In a Creepypasta - influenced upbringing, he would lack the sense of wonder and naivete that he had in the original series. He would be constantly on edge, expecting the worst to happen at any moment. His interactions with others would be more guarded and less friendly. He might not be as quick to form deep bonds with his classmates as he was in the normal story. Instead, he might keep people at a distance, fearing that they could be hiding some dark secret or be part of a sinister plot. His confidence would also take a hit, as the world around him would seem so much more unpredictable and dangerous.
His personality would be a lot darker. Instead of being the brave and somewhat innocent Harry we know, he'd be more cynical. He might not believe in the good of people or magic easily. Since Creepypasta often involves elements of betrayal and hidden evils, he'd be constantly looking for the worst in situations. For example, when meeting new people at Hogwarts, he'd be more suspicious rather than open - minded like in the original story. Also, his sense of humor would probably be a lot more macabre.
He'd probably be more refined. The Delacours are known for their elegance, so Harry might have better manners and a more sophisticated way of speaking.
Well, since Moody is a very vigilant and somewhat paranoid character, Harry would be more observant. He would constantly be on the lookout for danger, like Moody does. His sense of humor might also be a bit darker, influenced by Moody's experiences in the wizarding wars. He might not be as quick to make friends, as he would be more focused on who could be a potential threat. Also, his view of authority might be different. Instead of always looking up to Dumbledore, he might question authority more often, as Moody is a bit of a maverick in his own right.
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.
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.
