Percy's relationship with the other demigods could change significantly. He could become a sort of mediator between the demigods and the father of the gods. This new role might earn him respect from some, but also envy from others who think he's getting special treatment. He might also have to make tough decisions that could affect the demigod community as a whole, which could further impact his relationships.
With the father of the gods himself, Percy's relationship could be complex. At first, he might be in awe or afraid. But as the story progresses, he could develop a sort of father - son bond if the father of the gods starts to see Percy as a key to solving his problems. However, this bond could also be tested if their goals start to diverge, and Percy has to choose between his loyalty to the father of the gods and what he believes is right for the demigod world.
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 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.
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.
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.
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 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.
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.
Their relationship would likely become even deeper. They would be partners not only in their heroic adventures but also in parenting. They would have to support each other in raising their child, like Annabeth helping Percy understand their child's academic needs while Percy might be better at teaching combat skills. They would also have to make decisions together about their child's future, whether it's about staying at Camp Half - Blood or trying to live a more normal life in the mortal world.
If Zeus was Percy's father in a fanfiction, Percy's relationships with other demigods would change drastically. Percy has always been a bit of an outlier among the demigods, but this would take it to a whole new level. Those who were his friends before might start to question his motives. They might wonder if Percy will start to side more with the gods, especially Zeus, and abandon the demigods' cause. Percy would also have to deal with the fact that some demigods might try to use him as a way to get to Zeus. For example, they might ask him to put in a good word for them or try to get information from him about Zeus's plans. This could put a strain on his relationships as he has to figure out who he can trust among the demigods while also dealing with his new identity as Zeus's son.
