What would be the main differences in Harry's character if he was raised by McGonagall in fanfiction?

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.

If Harry was raised by Sauron, his character development would be complex. At first, he would be molded by Sauron's teachings. He would be confident in using dark magic and have a certain arrogance. However, as he interacts with the wizarding world or discovers his past, things would change. He could start to feel empathy for those who oppose Sauron. His magic might transform from being purely dark to something more nuanced, as he tries to reconcile his upbringing with his true nature. He might even become a sort of anti - hero, not fully on the side of good or bad, but trying to make things right in his own way.

Harry would probably be more physically fit and combat - ready. Sasuke would train him in ninja ways, so he'd be better at hand - to - hand combat compared to the regular Harry. His approach to facing enemies would be more direct and less about relying solely on magic. He might also be more independent, as Sasuke is not one to encourage over - dependence on others.

His character would become more self - reliant. On Kamino, he may not have the same support system as in Hogwarts. So he'd learn to fend for himself faster. He'd also be more adaptable to new and strange situations as Kamino has a very unique environment.

He'd be tougher. Hela's not one to coddle, so Harry would have to grow up fast.

Harry would be less socialized in the typical human way. He might not understand things like friendship the same way. He could be more territorial and protective. His magic might also be affected. He might use it more instinctively, like using a spell to protect his 'territory' which in this case could be the area where his wolf pack lives.

If raised by Hera, Harry would develop a more regal and commanding presence. Hera's teachings would shape him into a more disciplined wizard. He would probably be less impulsive and more calculating in his actions, having learned from Hera's strategic mind. His sense of right and wrong would be more firmly rooted in the grander ideals of justice that Hera represents, rather than just the simple good - vs - evil of the wizarding world.

Harry Potter's character, if raised by Flamel in fanfiction, would be a blend of Flamel's wisdom and his own innate courage. He would be more patient, having learned from Flamel's centuries - long experience. His sense of justice would be more refined, as Flamel could teach him about the long - term consequences of actions. He might also be more independent, as Flamel would encourage him to explore magic on his own terms, while still providing guidance when needed. This would make him a more well - rounded and formidable wizard in the wizarding world.

He'd likely be much more morally ambiguous. Harry would probably have less regard for the rules and traditions of the wizarding world.
