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.
In a 'Percy Jackson adopted by Artemis' fanfiction, Percy's relationship with his father Poseidon would be in turmoil. Poseidon might not understand why Percy has joined Artemis. With the Hunters, Percy would start to see female demigods in a different way. He'd have to respect their traditions and ways, which would be a big change from his previous experiences. His relationship with Artemis would be complex. She'd be strict but also caring, and Percy would have to learn to navigate this new dynamic while still holding onto his own identity.
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.
In his family relationships, Sally Jackson would be in for a big surprise. She would have to adjust to seeing her son as a daughter. Percy would have to deal with different family expectations as a girl. His relationship with Poseidon would also be different. Poseidon might be confused and perhaps less likely to immediately offer the same kind of support he did when Percy was a boy. And Percy's romantic interests, if any, would have to be re - evaluated. He might find himself attracted to different people or be the object of different types of attraction.
With the other demigods, Percy could become an outcast at first. They might see his adoption by Erebus as something unnatural or dangerous. But as time goes on, if Percy uses his new powers and influence for good, he could gradually regain their trust and respect. For example, he could use his shadow - related abilities to help in battles or rescue missions, showing that he's still on their side.
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 likely become more complex. She might be a bit worried about Percy's new powers and what they could mean for his safety and their future together. But at the same time, she would be there to support him as always.
With his friends at Camp Half - Blood, Percy might become a bit of an outlier. His connection to Zeus through the blessing could make some of his friends who are more closely tied to Poseidon or other gods feel a bit uneasy. However, it could also earn him respect from those who admire Zeus' power. Percy would have to work hard to maintain his friendships while dealing with this new dynamic.
In a 'Percy Jackson Father of Chaos' fanfiction, Percy's relationships would be in upheaval. His friendship with Grover would face a test. Grover, who has always been Percy's loyal friend, would now have to deal with a Percy who is unpredictable at times. Percy might accidentally cause chaos that affects Grover's nature - related tasks. With the other demigods at Camp Half - Blood, Percy would become a sort of enigma. Some would look up to him as a new kind of hero, while others would be jealous of his new - found power. His relationship with the sea gods, like Poseidon, would also change. Poseidon might be proud that his son has such a powerful new role, but also worried about how Percy will use his powers and how it will reflect on the sea god's domain.
His relationship with Annabeth would be really interesting. If Percy is reincarnated as Theseus, he might be more headstrong in his decision - making, which could cause some friction with Annabeth who is used to the normal Percy. For example, in planning a mission, Percy (as Theseus) might make a bold move without consulting her first.
Percy's relationship with the other campers at Camp Half - Blood would be a rollercoaster. The children of Poseidon might feel a bit betrayed or confused, as they thought Percy was one of their own. However, Percy could use his new status to bridge gaps between different cabins. For example, he could work with the children of Aphrodite to improve relationships in the camp, since Hera has some connection to love and relationships in a different way than Aphrodite. With the gods, his relationship with Zeus would be extremely strained, given Zeus's past issues with Hera. But he might find new allies among the gods who are friendly with Hera, like Hephaestus. Overall, Percy's relationships would be a mix of challenges and new opportunities.
