In this kind of fanfiction, it might be related to the idea that Percy has a connection to a primordial force. This force could have been around before the gods came into being. For example, if Percy has a link to the very essence of the universe that was there before the gods were created, it could make him seem older in a very fundamental way. This could also tie into his powers, like his control over water. If water is seen as a more ancient element than the gods themselves in the context of the story, his power over it could contribute to this idea of being older.
The implications are far - reaching. His being older than the gods might rewrite the entire mythology of the Percy Jackson universe in the fanfiction. It could lead to new alliances and enmities. Other demigods might look up to him as a new kind of leader, one who has a different kind of wisdom. This could also affect the magical items and their significance. Maybe some items that were once considered powerful because of their god - given nature are now seen as less important compared to whatever ancient power Percy might possess. And the whole concept of fate and prophecy could be turned on its head, as Percy's 'older' status might put him outside the normal flow of destiny as dictated by the gods.
Another way is to have the New Gods bring in a new type of magic or technology to the Percy Jackson universe. This could change the dynamics of how demigods operate. For example, if the New Gods introduce a magic that can enhance a demigod's weapon but at a cost, Percy would have to decide whether to use it or not.
Maybe Percy unknowingly breaks some ancient and very strict laws of the Gods. For example, he might interfere with some sacred rituals or places that are off - limits to mortals, even demigods like him. In the fanfiction world, the Gods could be very unforgiving when it comes to such violations and decide to kill him as a result.
Well, in fanfiction, anything can happen. There are fanfictions where the author wants to create a really unique scenario and might make Percy Jackson older than Chaos. But it's important to note that this goes against the traditional understanding of the Percy Jackson lore where Chaos is like the very first thing, the origin. But in the wild world of fan - created stories, the age relationship between Percy and Chaos can be flipped just for the sake of an interesting plot.
Maybe he wants to change the system. Percy has always been a bit of a rebel, and in fanfiction, he could see the gods' rule as corrupt or unfair. So, killing them could be his way of starting anew and creating a better world for demigods and mortals alike. Another motive could be to prevent a greater evil. If he discovers that the gods are planning something that would destroy the world, he might decide that killing them is the only way to stop it.
It might start by showing Naruto's first encounter with the gods. Maybe he witnesses an act of godly power that he finds disturbing or unjust. This initial reaction could set the stage for his growing hatred.
One implication could be a shift in the power hierarchy. Percy might have a different kind of authority or status. For example, he could be seen as a more dominant force among the supernatural beings.
Well, it could start with Percy being framed for a crime he didn't commit by the gods. This false accusation makes him feel extremely betrayed. He then has to go on the run while trying to prove his innocence. Along the way, he meets other outcasts and together they form a resistance against the gods. They might try to find a way to hold the gods accountable for their actions and create a new order where demigods are treated more fairly.
First, do your research on both Percy Jackson lore and Hindu mythology. Know the powers, personalities, and backstories of the characters from both. For instance, if you want to include Krishna in your fanfic, understand his role as a trickster and a divine figure in Hinduism. Then, think of a unique plot that can bring these two worlds together. Maybe it's a prophecy that involves both demigods and Hindu gods.
They are often portrayed as powerful and binding forces. In many fanfictions, the characters are acutely aware of the gods' promises and they structure their actions around them. For instance, if a god has promised protection to a certain demigod, other characters will take this into account when dealing with that demigod.
