Harry Potter's character would likely develop a stronger sense of independence. Since Jack Frost is often portrayed as a solitary figure, Harry might learn to rely on himself more. He could also develop a sense of wonder for the natural elements, especially ice and snow. His values might shift towards a more elemental view of magic, and he might be less interested in the politics and social hierarchy within the wizarding world. His sense of justice could still be strong, but it would be more in line with the unyielding nature of ice, being very firm and unwavering.
He'd be more disciplined. His character would be shaped by military values. He'd be less likely to act impulsively and more likely to think things through strategically.
He'd be tougher. Hiei's no - nonsense attitude would rub off on him. Harry would be more likely to take risks without hesitation.
Harry's character would be more attuned to the deeper magics. He would be less likely to jump into things without thinking. Since Flamel is a master of alchemy, Harry might be more interested in the scientific aspects of magic. He would also have a greater respect for life and magic's power, as Flamel, with his long life, would instill in Harry a sense of wonder and caution about the forces they deal with.
If Harry Potter were raised by Jack Frost in a fanfic, it would be a wild ride. Jack Frost is often depicted as a bit of a loner and a trickster. Harry could inherit these traits. His magic would likely be a blend of Hogwarts - style magic and Jack Frost's ice powers. He might use his ice powers to create magical ice sculptures that have real magical properties. His relationship with Hogwarts itself could be different. Instead of being in awe of the castle like most students, he might see it as just another place, and be more interested in the frozen landscapes around it. Also, his dueling style could be very unique, incorporating ice attacks and defenses that would surprise his opponents.
If raised by Emma Frost, Harry Potter's character would undergo significant changes. Emma's strong - willed and elegant nature would rub off on him. He'd be more assertive and perhaps more stylish in his appearance and behavior. Emotionally, he'd be more stable as Emma could guide him through the complex world of feelings. In the wizarding world, he might approach challenges with a different mindset, one that combines Emma's strategic thinking and his own magical instincts. He'd also likely have a different view of relationships, as Emma's view on interpersonal connections could shape how he interacts with others.
His character would become more rugged. Instead of the somewhat sheltered and naive Harry we see at the start of the original series, he'd be tough - minded. Burt Gummer's influence would make him more of a fighter from the get - go.
Harry would be more daring. Jack Sparrow's influence would make him less afraid of taking risks. In the wizarding world, this could mean he'd be quicker to explore dark and dangerous places. He might not wait for permission or for a group to support him, but rather just dive in like Jack does when facing a new situation on the sea.
Harry's character would become more centered around self - improvement. Goku is always striving to get stronger. So Harry would constantly be looking for ways to improve his magical and physical skills. He might not be as reliant on his friends for support in difficult situations as he is in the original story, instead trying to handle things on his own more often. This could make him seem a bit more independent and self - sufficient.
He might be more solitary at first. Since ghosts are not as social as living beings in the traditional sense, Harry could be used to his own company. But as he gets to know the living world more, he would start to open up.
His character would likely be much more aggressive. Trigon's influence would push Harry to be more assertive and less hesitant. He'd probably have a quicker temper too.
