If Harry was raised by the Malfoys in fanfiction, his character development would be very different. Firstly, his social skills might be more attuned to the Slytherin way of thinking. He'd be more calculating and less impulsive. His sense of right and wrong might be blurred initially as the Malfoy values would be instilled in him. For example, he might not see muggles in the same positive light as in the original story. But as he experiences more of the wizarding world outside the Malfoy Manor, he could start to question the beliefs he was raised with and undergo a transformation. This transformation could be a long and arduous process as he has to unlearn a lot of the Malfoy - influenced ideas and find his true self.
Harry's character development would be a sharp contrast to the original. Growing up with the Malfoys, he'd be exposed to a world of privilege and elitism. He might start off being more arrogant and self - centered. However, as he grows older, he could have an internal struggle. He might realize the wrongness of the Malfoy's ways and strive to break free, or he could be torn between loyalty to the family that raised him and what he believes is right in his heart. This would make his character arc more complex and less straightforward compared to the canon Harry.
He'd be more likely to be initially haughty. Since the Malfoys are known for their pride in their pure - blood status. But he might also grow to be more cunning as he'd be in an environment where manipulation is sometimes used.
He might be more reserved. The Malfoy upbringing would likely make him less impulsive compared to his canon self. He could also be more calculating in his actions.
Harry would likely be more confident in his pure - blood status, at least on the surface. Since he's raised by the Malfoys' twins, he'd be exposed to the pure - blood elitist culture from a young age. He might be more calculating and less impulsive than in the original story, having learned from the Malfoy family's shrewd ways.
He might be more arrogant. Growing up with the Malfoys, he'd be used to thinking his family was superior. He'd lack the humility Harry in the original series has.
His personality would likely be more reserved and calculating. Growing up with the Malfoys, he'd be taught to keep his emotions in check and think before acting. He might be more aloof towards others outside of the pure - blood circle at first.
Harry would be more territorial. Goblins are known to be possessive of their spaces and belongings. So, Harry would probably be very protective of his personal space and things. Also, his sense of justice might be different. Goblins have their own rules and laws, and growing up with them, Harry would view right and wrong from a goblin - centered perspective rather than a wizard - centered one.
He'd be more animalistic. He might move on all fours more often and be more comfortable in the wild. His communication skills could be more primal, using grunts and gestures at first.
He'd be more in tune with his instincts. Instead of relying on the social norms of the wizarding world, he'd follow his gut feelings more. For example, in a dangerous situation, he might act like a wolf in a pack, assessing threats quickly and instinctively.
He would be more feral. The Xenomorphs' aggressive and survival - based nature would likely rub off on Harry. He'd be less hesitant in a fight compared to the original Harry, and more likely to use brute force along with his magic.
He'd be more aggressive. Greyback's influence would make Harry less hesitant in a fight. He'd be more likely to use brute force rather than relying on spells all the time.
He would be more refined. Royal upbringing would instill in him a sense of propriety and elegance that he lacks in the original story.
