Harry's character would develop in a more patient and self - assured way. Merlin's long - lived experience and his different approach to magic would shape Harry. Instead of the somewhat isolated and often confused boy in the original story, he would be more open - minded. He would be exposed to different magical cultures and ideas from Merlin, which would make him a more well - rounded wizard. He would also be more in tune with the ancient and hidden parts of magic, and this would give him a different kind of power and presence.
Harry's character development would be drastically different. Since Merlin has such a deep understanding of magic and its history, Harry would grow up with a strong sense of magic's purpose and his place in it. He would be less likely to rely solely on his friends for support as he would have Merlin's constant guidance. His view of the magical world would be more complex, seeing the political and power dynamics in a more nuanced way. He might also be more reserved in showing his powers, as Merlin would have taught him the value of secrecy in a world full of potential threats.
He would probably have a different view on magic. Crowley's knowledge of magic, which may be more on the dark side, would shape Harry's understanding. For example, he might be more willing to use magic for personal gain rather than for the greater good as he was taught in the original story. He could also be more proficient in some types of magic that are considered taboo in the normal wizarding world.
Harry could be more distrustful of adults. Since he doesn't have a positive family figure in the orphanage, when he meets the wizarding world adults like Dumbledore, he might be more skeptical and less likely to blindly follow them. Also, his sense of loyalty might be more focused on the orphans he grew up with rather than just his Gryffindor housemates at first. He might have a harder time adjusting to the hierarchical and sometimes elitist nature of the wizarding world, coming from an environment where everyone was more or less on equal footing in terms of being an orphan.
Harry would be more confident in his physical abilities. Since Raiden is a powerful fighter, he'd train Harry to be strong and fearless in combat. This would be different from the Harry we know who often relied on his wits and magic in dangerous situations. Harry might also be more stoic, like Raiden, and not show his emotions as easily.
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 develop a sense of divinity within him. Since he's raised by Greek gods, he'd have a different relationship with power. He wouldn't fear power as much as he might in the original story. Instead, he'd see it as a natural part of his being. He'd be more in tune with nature and the elements, like the gods are. His relationships with other characters would also change. He might be more aloof towards some of his Hogwarts friends at first, as he'd have this whole other world of experiences from his upbringing among the gods that they couldn't understand right away.
Harry would likely be more confident in the Muggle world. Since Tony Dinozzo would expose him to all kinds of Muggle situations from a young age, Harry wouldn't be as shy or out of place among Muggles as he was in the original story. For example, he might be more comfortable using Muggle technology.
His character would be more open - minded towards different species. Since Xavier promotes coexistence among mutants and humans, Harry would likely apply the same principle to magical creatures and non - magical people. He'd be less likely to have the pure - blood - centric views that some in the wizarding world hold.
If raised by Merlin, Harry would be more self - reliant. Merlin might not coddle him as much as others could. So Harry would learn to solve problems on his own. His understanding of the magical world's history would be much deeper, which would shape his character. He would be more respectful of ancient magic and traditions.
He'd be more self - reliant. Without the Dursleys' neglect, he wouldn't have that initial sense of being unwanted. He might be more open - minded towards the wizarding world from the start. For instance, he wouldn't be as shocked by magic as he was in the original story.
Harry's character would develop a greater sense of justice and order. Amelia Bones is associated with the Ministry of Magic and upholds the law. Harry would grow up with a stronger understanding of the wizarding legal system. He might also be more diplomatic in his approach to problems, having learned from Amelia's way of handling things in the wizarding community.
