Percy's self - identity would be completely shaken. He's always known himself as Poseidon's son, so being a son of Ares would force him to re - evaluate who he is. He might struggle with feelings of anger and a desire for power that he didn't have before. This could lead to a darker path for him at first, but through various experiences, he could learn to control these new aspects of himself and become a more complex and interesting character.
Percy would probably become more arrogant at first. But as he faces challenges related to his new identity, he'd learn humility. His loyalty to his friends might be tested as Zeus could demand things that conflict with his friends' interests. He'd also have to deal with the expectations of being the son of the king of the gods, which would shape his character in ways different from when he was just Poseidon's son.
Percy would likely become more regal and proud. Since Hera is associated with royalty, he might develop a more refined and authoritative personality. He could also become more calculating, as Hera is known for her scheming. For example, he might think more about long - term plans rather than just reacting impulsively like he used to.
Percy would likely be more brooding. Since Iapetus was often seen as a rather serious figure in mythology, Percy might inherit some of that solemnity. He could be more withdrawn, thinking deeply about his new identity.
Percy would likely become more devious. Growing up with Loki as an adoptive father, he'd be exposed to Loki's tricks and lies. So instead of his straightforward, if sometimes impulsive, nature in the original Percy Jackson stories, he might think more about the different angles of a situation before acting.
Percy would likely be more ruthless. Gaea's influence might make him less hesitant to use force or manipulation to get what he wants. For instance, he might not be as concerned about the well - being of mortals as he was in the original story.
His relationship with Annabeth would likely be strained at first. Annabeth might be skeptical or even a bit afraid of Percy's new 'Ares - side' as the god of war is not exactly known for his peaceful nature. However, over time, she could come to understand and accept this new part of Percy.
Percy would likely be more in tune with the concept of home and family. Since Hestia represents the hearth, Percy might be more nurturing and protective. He could develop a stronger sense of responsibility for the well - being of his friends as if they were his family.
He would likely become more aggressive at first. Since Ares is the god of war, Percy would be exposed to a lot of combat - oriented values. But over time, he might learn to temper that aggression with his own sense of justice. His confidence would also grow in a different way compared to when he was just Poseidon's son. He'd be more assertive in battle situations and less hesitant to use force when necessary.
Canon Percy is a son of Poseidon. If he were the son of Artemis and Orion, his character would be more reserved in terms of relationships. Since Artemis is associated with chastity, Percy might be more cautious about romantic involvements. Also, his combat style would be different. Instead of relying on water powers, he'd focus more on archery and hunting skills.
In this fanfiction, Percy's character development would be quite interesting. He would start to value the concept of sisterhood that the hunters have, even though he's not a girl. This could make him more protective of the group. His fighting style might change too, as he'd learn new techniques from the hunters. Percy would also develop a deeper sense of loyalty to Artemis, which would influence his decision - making. He might become more of a thinker rather than just a doer, as he'd have to consider the implications of his actions on the hunters and Artemis's reputation.
