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.
In this fanfiction, the Primordial Son of Chaos could be a character who has been in a slumber for eons. Percy accidentally wakes him up during one of his quests. Now, Percy has to deal with the consequences. The Primordial Son of Chaos might have powers that are completely unknown to the Olympian gods. Percy, with his wits and the help of his friends, tries to communicate with this being, hoping to find a way to either calm him down or direct his power in a positive way.
The fanfiction could explore a scenario where the Primordial Son of Chaos decides to test Percy. He creates all kinds of illusions and challenges for Percy to overcome. These challenges might involve facing Percy's own inner demons as well as physical battles against strange and powerful creatures created by the chaos energy. Percy has to rely on his training, his relationship with his friends, and his connection to the ocean to pass these tests and prove himself worthy in the eyes of the Primordial Son of Chaos.
A possible plot could be that the Primordial Son of Chaos is slowly being awakened by the actions of the modern world. Percy senses this disturbance in the fabric of the cosmos. He then embarks on a journey to find out more about this entity. Along the way, he meets old foes and new friends. The story could involve a race against time as Percy tries to prevent the full awakening of the Primordial Son of Chaos if it's going to bring destruction, or he could be trying to ensure its proper awakening if it's meant to bring balance.
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.
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.
Well, perhaps the plot involves Percy being hunted by various forces. The Olympians see him as a threat because of his Chaos lineage, and the minions of Chaos might think he's too much of an Olympian. He then has to form an unlikely alliance with some demigods and minor gods who believe in his unique potential. Along the way, he uncovers secrets about the origin of the gods and the true nature of the relationship between Hera and Chaos.
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.
Percy Jackson is definitely a main character. He's the one at the center of the 'son of chaos' concept. Then there are his friends from Camp Half - Blood like Annabeth. She might be involved in trying to understand Percy's new situation or helping him in his new adventures. Grover could also be there, being Percy's loyal friend as always.
In some fanfictions, Percy being the son of Chaos and Poseidon is a really cool concept. It often gives him even more power. He might be able to control not just water like a son of Poseidon but also have some chaotic powers. For example, he could disrupt the order of things in a battle, or create portals to different realms which are abilities not typically associated with a normal demigod.
Another main character could be Chiron. He has always been an important figure in Percy's life. In this fanfiction, he might be the one who first discovers Percy's connection to Chaos and tries to guide him. Or he could be struggling to understand how to deal with Percy's new situation, especially if Percy's powers start to have unforeseen effects on Camp Half - Blood.
Perhaps some of the minor gods who are tired of the traditional power structure in Olympus could be Percy's allies. They might see his rebirth as a son of Chaos as an opportunity to shake things up. Also, any being that has a connection to the concept of change or new beginnings could potentially side with Percy. This includes spirits of innovation or even some forgotten heroes who sense that Percy is the key to a new era in the world of demigods and gods.
