If in a fanfiction where Harry is related to a Basilisk, his character would develop a sense of otherness. He might feel like he doesn't fully belong among his peers at Hogwarts. His courage would take on a different form. Instead of just facing Voldemort and Death Eaters, he would also have to face the prejudices against the Basilisk. This could lead to him becoming more of an outcast, but also more self - reliant. He might start to explore the ancient and often - feared magic associated with the Basilisk, which could expand his magical knowledge and abilities in unique ways.
In a Harry Potter as a Basilisk fanfiction, Harry's character development would be significantly altered. He would have to come to terms with the fact that he has a connection to a creature that has been a symbol of evil in the wizarding world for so long. This would make him question his own nature. His relationships with his friends would also be affected. Hermione, for example, might be initially horrified and try to persuade Harry to sever his connection with the Basilisk. Ron might be more fearful and keep his distance. However, through these challenges, Harry could grow into a more complex and powerful wizard. He would have to learn to control and use the Basilisk - related powers in a positive way, which would require him to mature faster and develop a deeper understanding of magic and its moral implications.
Harry would likely become more feared by some in the wizarding world. Since the Basilisk is often seen as a terrifying and dangerous creature, his connection to it might make others view him with suspicion. He would also have to grapple with the darker side of magic that the Basilisk represents, which could make him more brooding and introspective.
He'd likely be more inquisitive about different forms of magic. Instead of just relying on the spells taught at Hogwarts, he'd constantly seek out new magus - based knowledge.
He'd be more confident. With a loving mother around, he wouldn't have the insecurities that came from growing up with the Dursleys.
His magical abilities might develop in a different way. The Malfoys could introduce him to different types of magic or magical artifacts. Maybe he'd learn more about the Dark Arts in a different context, not for evil purposes but just to understand it better. He could also become more skilled in areas like Occlumency earlier on, since the Malfoys might see it as an important skill to protect their family secrets. His relationship with his Gryffindor traits would be tested. He might still have his bravery, but it could be expressed in different ways, like standing up to the Malfoy family's wrongdoings.
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.
He'd be more confident. With Sally's love and support, he wouldn't have the self - doubt that he had in the original story. He'd be quicker to trust people and might be more open - minded about different forms of magic.
Harry would likely be more cynical. Without the love and support of his parents, he'd grow up feeling abandoned. He might be more distrustful of others, especially those who claim to be helping him. For example, he might not trust Dumbledore as easily as in the original story.
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.
Harry's character would develop very differently. In the original series, he was an orphan with a sense of loneliness. But as Cersei's son, he would be in a position of power from the start. He would be groomed for leadership in Westeros. However, his experiences at Hogwarts would introduce him to a different kind of community. His relationships with his classmates would be strained at first due to his family's reputation. But over time, he could learn to be more empathetic and use his power to bring about positive change in both Westeros and the wizarding world, breaking away from some of the more negative Lannister traits.
