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.
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.
With his friends from Camp Half - Blood, things would be a lot more complicated. Some might look up to him as someone with extraordinary power, but others might be jealous or feel threatened. His relationship with Chiron would also change. Chiron would have to be extra careful in guiding Percy, knowing that his actions could have far - reaching consequences due to his unique parentage. And when it comes to his enemies, like the monsters, they might be even more determined to defeat him, seeing him as a greater threat to their plans than before.
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.
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 his friends like Grover, Percy would seem like a completely different person. Grover is used to Percy's emotions guiding his actions. Now, Percy would be cold and calculating. His friends would have to constantly remind themselves that this is still Percy, but it would be hard for them to connect on the same level. They might start to doubt if they can still trust him, as his lack of emotions could make his decisions seem unpredictable.
His powers would likely become more god - like. He might gain the ability to control lightning, like Zeus. Also, his strength and speed could be enhanced to a much greater degree. His control over water, which was his main power before, could also be amplified and perhaps combined with his new lightning powers in some unique ways.
His relationship with the gods would be complex. The gods who are friends with Ares might be more favorable towards Percy. However, the ones who dislike Ares, like Poseidon in some ways, might be disappointed in Percy. Poseidon might worry that Percy is being led astray by Ares and could try to persuade him to give up this new role.
Percy's relationship with the gods would definitely change. They would see him as a threat, especially if he stole a power that was close to their domain. Zeus, for instance, would be furious and might send all kinds of challenges and threats Percy's way, which would put Percy in a very difficult position.
In a Percy Jackson vampire fanfiction, his relationships would be transformed. His friends at Camp Half - Blood would likely be very wary of him. They've fought against monsters, and now Percy is something that was once considered a monster. His relationship with his mother would be difficult. She'd have to accept that her son is now a vampire. And with Annabeth, it would be a complex situation. Their love would be tested as she tries to understand and accept this new version of Percy.
If Percy becomes the Champion of Chronos, his relationship with his father Poseidon would be complex. Poseidon might try to free Percy from Chronos' influence. Percy's relationships with his fellow demigods would be full of suspicion. They would be constantly watching him to see if he shows signs of following Chronos' evil intentions. However, Percy could also use this new position to bring together characters who were previously at odds. For instance, he could broker a truce between two warring groups in the demigod world by showing them the greater threat of Chronos.
