Well, it could be that there is a prophecy about Percy becoming king. As he fulfills the different parts of the prophecy, he gradually gains the power and status. For instance, he might first gain the loyalty of some minor gods. Then, as he proves himself more and more, the major gods start to see him as a potential leader. And finally, through a grand ceremony, he is made king. Another way could be that there is a power vacuum among the gods. Percy steps in and through his strength and charisma, he is able to claim the throne.
Yes, in some fanfictions, Percy is often reimagined as the king of the gods. Writers like to play with the traditional mythology and give Percy this exalted status for creative and interesting storylines.
Percy could also become corrupted in fanfiction if he experiences great loss or betrayal. If he loses someone very close to him and blames the wrong people, he might seek revenge in a way that corrupts his moral compass. He could start using underhanded or unethical means to get what he wants, which is a form of corruption.
Zeus ascended to the position of the king of the gods through a combination of his divine powers, bravery in confrontations, and the support of some allies. His victory was hard-earned and marked a new era in the pantheon.
At first, Percy could be in shock. He can't believe that the gods, whom he has served and trusted, would betray him. But then, as the reality sinks in, he might become determined to get justice. He starts to plan his next moves carefully, using his wits and the skills he has learned over the years. He may also feel a sense of sadness and loneliness, as he realizes he is now on his own against the powerful gods.
Well, it could affect the plot in various ways. The gods' possessiveness might mean that Percy has limited freedom. He may constantly be under the watchful eyes of the gods, which restricts his actions. Also, it could lead to power struggles among the gods themselves, with Percy caught in the middle. Maybe one god tries to protect Percy from the others' possessive actions, adding more twists to the story.
Well, in many such fanfictions, Percy's relationship with the gods often starts with their initial interest in him. Maybe it begins with a particular god noticing his unique abilities. As the story progresses, the gods might start to interfere more in his life, either to help or hinder him. For example, a god could offer him special powers or tasks that lead to a deeper connection. Sometimes, there could be rivalries among the gods over Percy, which also shapes their relationship.
Percy's character would develop in many ways. Firstly, he'd gain a deeper understanding of the politics among the gods. This would make him more calculating and strategic. He'd also become more empathetic towards the gods' viewpoints, even if he doesn't always agree. His relationships with his old friends would change too. He might not be able to be as carefree with them as he used to be. Instead, he'd have to consider how his actions as king affect them and the entire demigod community. Moreover, his sense of responsibility would expand far beyond just protecting his friends and family to safeguarding the entire divine and mortal worlds.
At first, Percy might be hesitant and conflicted about killing the gods. He's always had a complex relationship with them. But as he's pushed further into the situation, he could become more hardened. Maybe he starts to see the gods as truly corrupt and that killing them is the only way to save the world. This would make him more decisive and perhaps a bit more ruthless.
Percy would interact in a cautious yet curious way. He'd be curious about their powers, like Anubis' role in the afterlife. But he'd also be cautious as he doesn't know how they'll react to a Greek demigod. He might use his charm, which has worked on some Greek gods, to try and build relationships. However, he may face some resistance from the more xenophobic Egyptian gods who see him as an intruder.
In the fanfiction, the overprotectiveness might show up as the gods restricting Percy's actions. They may not let him go on certain quests alone, insisting on sending a whole entourage of helpers. This could be because they see Percy as a very important asset, and they're afraid of losing him. So they overcompensate by being overly protective.
