Obviously, Percy Jackson himself is a main character. He's the focus as the adopted son of Chaos. Chaos would also be a major character, as Percy's adoptive father. There might be appearances from old friends like Annabeth. She could be worried about Percy in his new situation or even try to help him. Another character could be some of the primordial deities related to Chaos. They might be either allies or antagonists to Percy depending on the story.
One interesting plotline could be Percy's struggle to adapt to his new role as the adopted son of Chaos. He might have to deal with new powers that are both a blessing and a curse. For example, he could have the power to manipulate the very fabric of reality, but it comes with the risk of losing his humanity. Another plotline could be Percy facing off against old enemies from his past in the Percy Jackson series, but now with his newfound powers and status. It would be a test of his loyalty and how much he has changed.
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.
In this fanfiction, there might be a lot of focus on Percy's relationship with the other wolves in Lupa's pack. He could learn their ways of survival, their hierarchy, and how to be a part of their community. This would be a great way to explore his adaptability and growth.
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.
One plot idea could be Percy's struggle to balance his new identity as Lady Chaos' adopted son with his existing relationships in the demigod world. He might face suspicion or envy from his old friends. Another idea is that he discovers new powers related to chaos, which he has to learn to control quickly to face an emerging threat. Maybe there's a prophecy that only he, as the son of Lady Chaos, can fulfill, leading him on a quest across different realms.
Well, of course, Percy Jackson himself often makes an appearance. He could be a mentor figure to the adopted son, guiding him through the ropes of being a demigod. Annabeth is also common, perhaps helping the adopted son with her wisdom and knowledge of the mythological world.
The setting of the story might shift a bit. Instead of always being at Camp Half - Blood or on quests related to the Greek gods, Percy could be in the territory of the wolves. There could be new threats and challenges there, like rival wolf packs or ancient enemies of Lupa. And all these elements would make for an exciting and different take on the Percy Jackson universe.
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.
