It could be the Titans or some new creatures that are jealous of Percy's connection to Chaos. They might see Percy as a threat and try to stop him and Perlia from achieving their goals.
Well, the plot could involve Percy's newfound status as the son of Chaos bringing all kinds of chaos (pun intended) to his relationship with Perlia. Maybe he has new powers that are hard to control and Perlia has to help him. It could also be about them facing new enemies together that are drawn to Percy's connection to Chaos.
Well, one key element could be the unique relationship between Percy Jackson and the realm of Hades. Since he's the son of Hades in this fanfiction, it might explore how he deals with the dark and mysterious powers associated with his father. Also, in terms of 'Perlia', it could be about a relationship or adventure that involves Percy and a character named Lia. Maybe their story is set against the backdrop of the mythological world, with battles against various monsters and challenges that test their bond.
In some fanfictions, Percy Jackson is indeed portrayed as the true son of Chaos. Writers often take creative liberties to explore new storylines and character developments. This idea can lead to very interesting and unique plot twists, such as Percy having powers beyond what we see in the original series.
It changes the dynamic a great deal. Percy's new identity as the son of Hades makes him darker and more brooding perhaps. This could make the relationship with Lia in 'Perlia' more complex. He might be more cautious and secretive, which could lead to misunderstandings in their relationship.
The plot could center around Percy's transformation into the 'Son of Chaos'. He might have to face challenges that test his loyalty to his old friends at Camp Half - Blood while also adapting to his new role. He may also encounter new characters who are either allies or enemies in this new phase of his life. It might also involve a power struggle within the chaotic realm where he has to prove himself worthy.
One possibility for a Percy Jackson fanfiction centered around the Primordial Son of Chaos could be a story where Percy discovers a hidden prophecy related to this powerful being. Maybe he has to team up with some unlikely allies, like a group of minor gods who are also interested in the balance that the Primordial Son of Chaos might disrupt or uphold. This could lead to a series of adventures across different realms, including Tartarus, where they search for clues about the true nature of the Primordial Son of Chaos.
It depends on the specific Perlia fanfiction. Some might focus on Percy's immortality deeply, showing how it affects his adventures in new and different ways. For example, they could write about how he feels when he watches his mortal friends age while he remains the same. Others may just mention it in passing as part of the established character trait.
In my opinion, it has its merits. It takes the familiar Percy Jackson world and turns it on its head. If you're a fan of the series and like to see alternate versions of the story, this fanfiction could be really interesting. It could delve deeper into the concept of Chaos and how that affects Percy's life. For example, his relationships with other characters might be completely different, and the way he views the world of gods and monsters could change too.
If Percy is the son of Chaos in fanfiction, it would change his relationship with the gods. They might view him with more suspicion or even fear. Also, his role in the world of demigods could be redefined. Instead of just being a hero for Camp Half - Blood, he could be seen as a more cosmic figure with a much larger purpose.
