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.
His view of the world would be shaped by the Xenomorphs' perspective. Harry would see the wizarding world as a place full of soft and naive beings at first. He would have a more alien - like view of magic, perhaps using it in ways that are not traditional. For example, he might use magic to create structures similar to Xenomorph lairs for protection rather than the typical wizard homes. His moral compass might also be different. While he still has his inherent good nature, his idea of right and wrong could be influenced by the Xenomorphs' code of survival, which could lead to some interesting conflicts when dealing with the more civilized wizarding society.
If Harry was raised by Potter elves in fanfiction, his character would be very different in several ways. Firstly, his sense of family would be much broader. The elves would be like his extended family, and he would have a deep - rooted loyalty to them. This would make him more inclusive when it comes to making friends at Hogwarts. Instead of just sticking to the Gryffindors, he might befriend students from all houses. Secondly, his relationship with power would be different. The elves don't seek power in the way wizards do. So, Harry would be less interested in fame and more interested in using his magic for the good of all. He would be more of a behind - the - scenes helper rather than a spotlight - seeking hero. And finally, his understanding of magic would be more practical and down - to - earth. Elves use magic for daily tasks, and Harry would learn this kind of magic first. So, when he goes to Hogwarts, he might be able to solve problems in a more unorthodox but effective way compared to the other students.
He would be more cynical. Demons are not known for their positive outlooks. So Harry might not trust easily. He'd also likely be more aggressive in achieving his goals, as demons often value power and dominance. His view of magic would be more skewed towards the dark arts.
He might be more laid - back. Irish culture has a certain charm and easy - going nature, so Harry could be less uptight than in the original. He could also be more superstitious due to Irish folklore.
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'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'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.
Harry would likely be more wild in a sense. Dragons live by their instincts, and he'd pick up on that. His magical abilities could be more primal. Instead of relying on the spells taught in Hogwarts, he might use magic in a more raw and unrefined way. Also, his sense of loyalty might be more towards the dragons rather than the wizarding community initially.
He would be more refined. Royal upbringing would instill in him a sense of propriety and elegance that he lacks in the original story.
