Percy could also try to appeal to Zeus's sense of reason, if he has one. He could argue that being a demigod is what makes him special and that forcing him to become a god would disrupt the natural order. He could remind Zeus of the importance of balance between mortals, demigods, and gods.
One consequence could be Percy losing his human connections. His relationships with his friends and family were based on his shared humanity. As a god, he might find it hard to relate to them in the same way. For example, his mortal friends may age and die while he remains an immortal god, leading to a sense of isolation.
When writing Percy, think about his backstory. He grew up knowing his divine heritage, which could have both positive and negative impacts. He might have been bullied by other demigods out of jealousy, so he has a bit of a guarded side. But he also has a strong sense of justice, inherited from Zeus, which makes him always ready to stand up for the weak. His relationship with his parents should also be explored. He could have a closer bond with Leto as she was more present in his life, while Zeus was often distant due to his many responsibilities in Olympus.
First of all, Percy's natural courage plays a huge role. He's not one to easily cower in the face of an Evil God. His courage gives him the initial push to resist any kind of mental or emotional manipulation. Then, his knowledge of the demigod world and its history can be a weapon. By understanding how Evil Gods have worked in the past, he can anticipate their moves. He could also seek help from other powerful beings like the Oracles or some of the more neutral gods. His friendship with Grover and Tyson also gives him an anchor. Their unwavering support and unique abilities can assist Percy in warding off the Evil God's influence. And finally, Percy's own moral compass, which has been developed over his years of adventures, will always guide him away from the dark path the Evil God wants to lead him down.
In the fanfiction, Percy's relationship with Zeus may develop gradually. Zeus, being a powerful and often aloof figure, might initially be distant from Percy. But as Percy shows his courage and abilities, Zeus could start to take a closer interest. This might lead to Zeus mentoring Percy in some ways, teaching him about godly powers and responsibilities.
In some fanfics, Zeus might be possessive of Percy because Percy represents a powerful force or potential. Zeus, being the king of the gods, wants to control all sources of power. Percy's abilities and his role in the demigod world could make Zeus see him as something to be owned or at least controlled.
The story of Percy and Zeus' friendship could begin with Percy being summoned to Olympus. Zeus has been observing Percy for a while and is intrigued by his abilities. At first, there is tension between them. But as they are forced to work together on a mission to retrieve a lost and powerful artifact, they start to see each other in a new light. Percy shows Zeus his loyalty and Zeus offers Percy protection. This newfound friendship gradually changes the dynamic between demigods and gods, leading to a more harmonious co - existence.
A fanfic about Percy, brother of Zeus, could start with Percy feeling a sense of isolation. Despite being part of the divine family, he doesn't quite fit in. He decides to leave Olympus for a while and explore the mortal world. There, he experiences the joys and sorrows of humanity in a way that Zeus never has. He falls in love with a mortal, which causes a huge rift between him and Zeus. This love story could be the central theme of the fanfic, with Percy having to choose between his family and his new - found love.
Percy would face several challenges as the god of time. For starters, there would be the issue of time paradoxes. If he meddles too much with time, he could create paradoxes that could have unforeseen and potentially disastrous consequences. Also, he would have to deal with the jealousy and fear of some of the other gods and demigods. They might see his new power as a threat and try to undermine him. Additionally, managing the balance between using his time powers for good and not becoming too controlling would be a constant struggle.
He could have the power of lightning, like Zeus. Maybe he can control it better than other demigods. Also, he might have enhanced strength and speed, similar to Zeus's own capabilities.
Another possibility is that Percy discovers some long - forgotten weakness of Zeus. In the world of fanfiction, the author could create a scenario where Percy stumbles upon an ancient prophecy or a hidden secret about Zeus. This knowledge could give Percy the upper hand. He could then use his wits and his powers to exploit this weakness and defeat Zeus.
