Harry could be more diplomatic. Edmund had to deal with different creatures and kingdoms in Narnia. So, as his son in fanfiction, Harry would have a natural ability to negotiate and get along with different groups, whether it's different houses in Hogwarts or different magical species. He would be more open - minded and less likely to jump to conclusions about people who seem different from him. For example, he might be more accepting of Slytherins and understand that they have their own reasons and loyalties, just like the different creatures in Narnia had their own motives and ways of life.
He might be more self - reflective. Since Edmund had his own character arc of learning from his mistakes, Harry could inherit that trait. He would be quicker to admit when he's wrong and more likely to learn from his experiences.
His sense of loyalty would be more complex. Edmund's experiences in Narnia made him very loyal to certain causes and people. Harry, as his son, would have a deeper understanding of loyalty. He would not just be loyal to his friends in Hogwarts, but also feel a sense of loyalty to Narnia and its inhabitants. This could make his decisions more difficult at times. For instance, if there was a conflict between Hogwarts and Narnia, he would have to weigh his loyalties carefully and try to find a solution that benefits both sides, rather than simply choosing one side over the other.
The plot could involve Harry facing challenges that are a combination of the threats in Narnia and the ones in the wizarding world. Since Edmund had his own journey of redemption in Narnia, Harry might inherit some of that sense of making up for past mistakes. He could use this to help his friends in Hogwarts who have made errors. For example, if a student has been lured to the dark side, Harry, with his Narnian - inspired values, tries to bring them back. And his connection to Edmund could mean he has a special relationship with Aslan, which gives him an edge in the fight against evil in both worlds.
He would likely be more conflicted. Harry was always a morally upright character, but with Thanos as his father, he'd have to battle inner demons. He might be more powerful physically and have a darker side to his personality that he constantly has to keep in check.
He would be much more physically powerful. Instead of relying just on magic, he could use his Saiyan strength to solve problems. For instance, he might be able to break through magically locked doors with his bare hands.
He would be more powerful. Harry would likely have a sense of grandeur and a different view of his place in the world. His confidence might soar as he realizes he has such a powerful lineage.
He would probably be more confident. Since the Mikaelsons are known for their assertiveness, Harry might inherit some of that trait. He could be more bold in standing up to his enemies, not just Voldemort but also bullies at Hogwarts.
He would be more physically capable. Instead of just relying on magic, he could use his Wakandan - trained combat skills. His confidence might also be different. Growing up in Wakanda could give him a stronger sense of self - worth and a more regal bearing, which would set him apart from the original Harry Potter.
He'd probably be more morally ambiguous. Growing up as Crowley's son, he might not have the same clear - cut sense of right and wrong as the original Harry. He could be more cunning and less hesitant to use underhanded tactics if necessary.
Harry would likely have a different set of values. Yugi had a strong sense of justice and friendship in Yu - Gi - Oh. As Yugi's son, Harry would place even more emphasis on these values. He might be more open to different cultures and beings, since the Yu - Gi - Oh world has a wide variety of characters. Also, his appearance might be a bit different, perhaps having some features that are more in line with the Japanese - inspired look of the Yu - Gi - Oh characters.
Harry would likely be more ruthless. Klaus has a reputation for being cruel when necessary, and Harry might have a bit of that in him. He may not hesitate as much to use more extreme measures against his enemies, like the Death Eaters. However, he would also have to struggle with this darker side of his nature, as he has been brought up in the relatively more morally - bound wizarding world. His friends like Hermione and Ron might be shocked at first by these new aspects of his personality, but they would also try to help him stay true to the good values he has learned at Hogwarts.
He would probably be more conflicted. His moral compass would be constantly tested. He might have a natural inclination towards power, like his father, but also have the good heart he developed growing up. So he'd be constantly fighting within himself.
