His relationship with Hermione would likely change as she might be both intrigued and a bit wary of his new powers. She would be eager to study his abilities but also concerned about how they might be used. With Ron, there could be some jealousy at first as Harry's powers would be so different and potentially stronger. But Ron would also come to rely on Harry's new abilities in times of danger.
In terms of his enemies, Voldemort would surely view Harry as an even greater threat. Harry's powers from Apollo and Artemis could be the key to finally defeating Voldemort. His relationships with the Death Eaters would be more intense. They might target him more aggressively. However, Harry could also find unexpected allies among the magical creatures, who are more attuned to his connection to Artemis. His relationships within the wizarding community would be in a state of flux as he tries to navigate his new identity.
His relationship with Annabeth would be very different. Annabeth might be initially scared of Percy because of his dark lineage. She would be cautious around him as she is used to the more 'typical' demigods. Percy, on the other hand, might feel isolated from her because he knows she is wary. His friendships with the other demigods at Camp Half - Blood would also change. Some might avoid him, while others might be intrigued by his new powers and origin. Grover, for example, might be torn between his loyalty to Percy and his fear of what Percy could become.
His relationship with Dumbledore would likely be more complex. Dumbledore would need to guide Harry in understanding and controlling his dragon - influenced powers. Hermione might be both fascinated and a bit jealous of Harry's new - found abilities, but still be his loyal friend and help him research about his heritage.
Harry's relationship with the Weasley family would change. Mrs. Weasley might be a bit more hesitant in accepting him at first, worried about the Black family's reputation. But over time, she would warm up to him. The Weasley twins would see him as an even better partner in pranks, given Sirius's reputation for mischief. And Ginny might have a different kind of crush on him, seeing him as more of a rebel and being attracted to his new family - related boldness.
His relationship with Dumbledore would likely become more complex. Dumbledore, who knew a great deal about Harry's past as a Potter, would now have to re - evaluate everything. Harry might feel a sense of betrayal that Dumbledore didn't know or didn't tell him this crucial part of his identity. With his friends, Ron and Hermione would be initially skeptical but then very curious. Ron might feel a bit overshadowed at first by Harry's new and even more 'special' heritage, but they would ultimately support him.
Harry's relationship with Dumbledore would also shift. Dumbledore would need to reevaluate his role in Harry's life. He might see Harry as a potential bridge between the wizarding world and the underworld, and try to guide Harry in using his new powers for good. At the same time, Dumbledore would have to be cautious as the underworld has its own set of rules and dangers.
Well, with his friends from Camp Half - Blood, Percy would be sort of an outlier. His friends might be a bit jealous of his powerful heritage at first. But as they get to know him better, they realize that he has his own set of problems. For example, he might be constantly watched by the gods more closely than other demigods because of his parentage. His relationship with Chiron would also change. Chiron would have to figure out how to train Percy with his unique combination of powers. And when it comes to the villains in the story, they might target Percy more because they see him as a threat due to his powerful parents. So, overall, his relationships would be in a state of flux and constantly evolving because of his special background.
His relationship with Ron would be very different. Ron might be initially distrustful or even hostile towards Harry in Slytherin. But as the story progresses, they could come to understand each other better. Harry's relationship with Hermione could also change. She might be more cautious around him at first, but then realize that Harry is still the same person deep down. And his relationship with Draco would be much more complex. They could start as rivals, but then become allies in some situations, as they both have a connection to Slytherin.
His relationship with Annabeth would definitely be affected. She might be a bit wary at first, since Nyx is such an unknown and powerful entity. But she would also be there to support Percy as he figures things out.
His relationship with Ron would be very different. Ron, who is used to a more traditional wizarding family, might be initially scared of Harry's Addams Family traits. But over time, they could bond over their shared love for adventure, although Harry's idea of adventure might be a bit more 'out there' like exploring haunted mansions instead of just the Forbidden Forest.
