In a fanfic where Harry is raised by Daphne Blake, his character development would be significantly different. Daphne's family likely has different values and traditions compared to the Dursleys or even the wizarding world in general that Harry experiences in the original series. Harry could grow up with a stronger sense of self - preservation, as Daphne might instill in him the importance of protecting oneself in a world full of potential threats. His relationships would also be more complex. For instance, his friendship with Neville might not develop in the same way, as Harry would be coming from a different social and magical upbringing. He might also be more in tune with the politics of the wizarding world, as Daphne could expose him to the power dynamics and rivalries at an early age. This would make him a more calculating and strategic character, rather than the somewhat naive and impulsive Harry we see in the original books at times.
Well, it could be that Daphne, being from a different magical world or background perhaps, raises Harry with a different set of magical knowledge. Maybe she'd introduce him to more Slytherin - like values in a positive way, different from what he would have learned at Hogwarts. Harry might grow up with a more refined and sophisticated magical upbringing, with an emphasis on things like potions and ancient magic that Daphne's family might be well - versed in.
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's character would be shaped by Sirius' values. Sirius values loyalty above all else, and Harry would grow up with a deeper understanding of what it means to be loyal to friends and family. He would also be more in touch with his emotions. Sirius, having suffered so much, would encourage Harry to express his feelings. This would make Harry a more well - rounded and emotionally intelligent character compared to the sometimes stoic Harry in the original series.
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.
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.
