His view of relationships could also shift. Growing up under Aphrodite's care, he'd be exposed to different types of love and relationships. He might become more empathetic towards those in love or those with relationship problems. He could start to see the world through the lens of love, which would make him more understanding but also potentially more vulnerable as he might let his emotions in relationships guide his actions more.
Percy might become more charming. Aphrodite is all about love and beauty, and her influence could make Percy more aware of how to present himself in an appealing way. He could start using more flattery and charm in his interactions, which would be a big change from his more straightforward, sometimes brash self.
His confidence might increase. Aphrodite is all about charm and allure, and being around her could rub off on Percy. He might become more self - assured in social situations, which is quite different from his sometimes - awkward self in the original stories.
His personality could change in several ways. For one, he might become more arrogant due to the association with Zeus. However, he could also become more responsible, realizing that he now represents Zeus in a way. He may also grow more distant from his old friends as he has to adapt to his new life among Zeus' domain, which could be full of more formalities and power plays.
Percy's personality could become more adaptable. The Avengers operate in a different world compared to where Percy is from. He'd have to learn new ways of doing things. So, he might become more flexible in his thinking and actions. Also, he could become more serious in some ways, as the Avengers often deal with high - stakes situations.
Percy might become more brooding. As a vampire, he's now part of a world that's often associated with darkness and mystery. He may also become more possessive, which is a common trait among vampires. For example, he could be overly protective of his territory or the people he cares about.
He'd probably be more aware of his appearance. Instead of just being a scruffy, normal - looking demigod, he might take more care in how he presents himself. He could also be more charming without really trying, which might get him into trouble sometimes as people might misinterpret his intentions.
Percy would likely become more nurturing. Since Hestia is associated with the hearth and home, Percy might pick up her values of warmth and care. He could be more empathetic towards others, especially those who are homesick or lost. For example, he might be more patient with new demigods arriving at camp.
His relationship with Annabeth would change. She might be a bit jealous at first of Percy's new connection to Hecate. But then she would see how his new powers could be useful. They would have to learn to work together in a new way, with Percy having different abilities to bring to the table. His friendships with other demigods like Grover would also be different. Grover might be a bit in awe of Percy's new magical side. Percy would also have to form new relationships with the followers of Hecate, who might be very different from the demigods he's used to.
When it comes to his relationship with Hera herself, it would be complex. At first, Percy might be resentful or confused about being adopted by her. But as time goes on, he might start to understand her in a way no one else does. Hera could start to see Percy as a true son, and this could lead to a deep, if somewhat unusual, bond between them. Percy would have to balance this new relationship with his existing ones, and it could lead to some really interesting character development and story arcs.
Percy's relationship with the male demigods would change significantly. Some might see him as a traitor for joining the Hunters. However, he would also gain new allies among the Hunters themselves. His relationship with Artemis would be that of a mentee and mentor at first, but as time goes on, it could develop into a more family - like bond. And his relationship with the gods would be different too, as he's now under Artemis's protection, which might make some gods view him in a new light.
The plot could also involve Percy having to deal with Aphrodite's rather unpredictable nature. Since she's the goddess of love, she might push Percy into various romantic situations that he's not used to. Maybe he has to navigate through a series of love - related quests, like helping two star - crossed lovers from different mythical beings get together, all while trying to maintain his own identity and hero status.
