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.
In such a fanfic, Harry's character would grow to be very self - reliant. He'd have been taught to be independent in the military environment. His sense of justice would be more like that of a military leader, aiming to protect the wizarding world as if it were his battalion. He'd also be more adaptable, having been trained to handle various situations in the military. This would make him a formidable opponent against Voldemort, as he could quickly adjust his plans and strategies.
Harry's character would develop in a more structured way. He'd have a strong sense of duty, like a soldier. His relationships would also be affected. For example, he might be more formal with his friends at first, but as they get to know him better, they'd see his loyalty. And in the face of danger, he'd be calm and collected, relying on his military - style training.
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.
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.
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'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.
His character would be more assertive. He'd be used to taking action quickly due to his Warrior upbringing. He might be less hesitant in difficult situations compared to the original Harry.
He would be more independent. Goblins are self - reliant, and Harry would likely pick up this trait. He would not be as reliant on others for help as he is in the original story. His view of power would also change. Instead of seeing power in terms of magic alone, he would understand the power that comes from wealth and influence within the goblin community, which could make him more politically astute.
His character would likely be more hardened. Growing up with the Akatsuki, he'd be exposed to a lot of tough situations and battles early on. This would make him less naive compared to the original Harry. He might be more cynical about the idea of pure good and pure evil, having been around the Akatsuki who operate in a more morally complex world. Also, his sense of loyalty might be different. While he'd still value his friends, it might be in a more guarded way as the Akatsuki don't always trust easily.
