Percy is the central figure. But there could be a female character who is a powerful warrior in the Chaos Army and has a special relationship with Percy, maybe a love - interest or a very close friend. And then there could be an old sage who provides Percy with valuable advice and knowledge, especially when it comes to dealing with the magical aspects of leading the army.
Obviously, Percy is the main character as the commander of the Chaos Army. There could also be his second - in - command, a character who is very loyal to Percy and helps him in making important decisions. Another main character could be the antagonist, perhaps a powerful wizard or a rival commander who wants to destroy the Chaos Army.
The main characters would include Percy. There might be a group of elite soldiers within the Chaos Army who are like Percy's personal guard and they play important roles in the story. Also, there could be a mysterious figure from Percy's past who resurfaces and has a major impact on the future of the Chaos Army, either for good or bad.
The Titans could be great antagonists. Even though they were defeated once, they could be making a comeback with new strategies and powers, seeing the Chaos Army as a threat to their plans of regaining dominance. Another option could be the Giants, who are also powerful and have a long - standing grudge against the demigods.
Obviously Percy is one of the main characters. There might also be the leaders of the chaos army. They could be some powerful and mysterious figures that Percy has to interact with. And perhaps some of Percy's old friends might also play a role, either trying to bring him back or having to face him as an enemy now.
A plotline might involve Percy being betrayed by one of his closest allies in the Chaos Army. This could lead to a series of events where he has to fight not only the external threats but also this new internal one. He could then go on a journey to redeem his ally or simply to take revenge. Also, the Chaos Army could be facing a new type of magic or technology that they've never encountered before, and Percy has to find a way to adapt.
There's no official 'athlon commander of chaos' in the original Percy Jackson series, so in the fanfiction, it could be an entirely original character created by the fanfic writer. They might be someone with a special connection to chaos, perhaps having powers related to disrupting order or controlling unruly elements.
One interesting plot idea could be Percy leading the Chaos Army against an ancient, powerful enemy that has emerged from the darkest depths of Tartarus. The army could consist of various mythical creatures from different pantheons, united under Percy's leadership. Another idea is Percy having to deal with internal power struggles within the Chaos Army, where different factions have different ideas about how to wage war.
The main characters are Percy and Thalia, of course. Percy, with his water - based powers and heroic nature, often takes the lead in many situations. Thalia, as a strong and fearless demigod, is right there with him. They both interact with the concept of Chaos in different ways in these fanfictions.
The main characters are Percy, who is brave and resourceful, and Calypso, who is both powerful and alluring. In the context of the chaos fanfiction, they are the ones who will drive the story forward. Their personalities, Percy's determination and Calypso's grace, will be on full display as they interact with the chaotic elements around them.
Obviously, Percy is a main character. Since he is the son of Chaos in this fanfiction, his character development and journey are central to the story.
Obviously, Percy Jackson is the main character. He is the one who becomes the soldier of chaos. His character development from a hero of the Olympians to a figure in the chaos realm would be a central focus.
Often in these types of fanfictions, aside from Percy, there might be minor characters that serve as catalysts for his actions. It could be a random villager who Percy saves, which then sets off a chain of events. Or perhaps an old mentor figure who appears briefly to give Percy some advice that helps him in his one - man battles.
