He would be more refined. Royal upbringing would instill in him a sense of propriety and elegance that he lacks in the original story.
Harry would likely be more assertive in a political sense. Since royalty often has to deal with power plays and politics, he would be better equipped to handle the complex power dynamics in the wizarding world. He might also be more conscious of his image and how he presents himself, as royalty is often in the public eye.
In this fanfiction scenario, Harry's character would be influenced by the values of royalty. He could be more haughty at first, used to getting his way. However, as he grows and experiences the real world outside of the royal bubble, he would have to learn humility. His view of friendship might also change. Instead of just having close - knit friends like in the original, he might have to consider the political implications of his friendships. His magical abilities might be developed in a more formal and structured way, as royal families often have strict educational regimens for their heirs.
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.
If raised by Calypso, Harry's character would be very different. His view of family would be centered around Calypso, and he would have a different understanding of loyalty. He would be more connected to the sea and nature in general. His magic would have a different flavor, perhaps more wild and less refined in the traditional Hogwarts sense. He might be more self - sufficient, having grown up in a more isolated environment. Also, his approach to dealing with threats like Voldemort would be unique, as he would draw on the magic and wisdom he learned from Calypso rather than just the typical spells taught at Hogwarts.
Harry would have a different view of leadership. Instead of just being a hero who reacts to threats, he would be more proactive in shaping the wizarding world. Lelouch's influence would make him see the importance of having a vision for the future and using all means necessary to achieve it. He would be more strategic in his approach to fighting against Voldemort and the Death Eaters, perhaps even trying to turn some of them to his side rather than just fighting them head - on.
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.
His personality would probably be more aloof. Since basilisks are solitary creatures, Harry might not be as sociable as in the original story.
His self - identity would be more complex. Instead of just being 'The Boy Who Lived', he would also be a black wizard in a predominantly white wizarding world. This would make him more aware of issues like racism and inequality from an early age. He might be more outspoken about these issues compared to the original Harry.
In such a fanfiction, Harry Potter might grow up with a completely different set of values. He could be trained in courtly manners, have access to vast resources, and perhaps be more politically astute. His relationship with the wizarding world might also be different, as he would approach it from a royal upbringing perspective.
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.
He'd likely be more attuned to the darker aspects of magic. Since the Hel Gods are associated with darker realms, Harry might not shy away from what's considered 'dark magic' as much as in the original story. He could be more of an outcast among the regular wizards who fear his different upbringing.
