One idea could be Percy being chosen as the Chaos Champion and having to face off against an ancient, long - forgotten evil that is emerging from the darkest corners of the Underworld. He'd have to use his new - found powers granted by Chaos in unique ways, like controlling the very essence of water in ways he never thought possible, such as turning it into solid light constructs for defense.
Maybe Percy as the Chaos Champion is sent on a quest to retrieve a powerful artifact that was stolen by a rogue demigod who wants to use it to overthrow the Olympians. Along the way, he meets new allies from different mythologies, like Norse dwarves who help him upgrade his weapons with their magic forging skills. And he has to constantly battle his own inner demons as the power of Chaos starts to influence his mind a bit too much.
I'm not sure specifically as there can be many different fanfictions with this title. But generally, it might involve Percy Jackson in some new adventures related to chaos. Maybe he has to face new threats or make alliances in a world where chaos is a major factor.
Well, a plot could involve Percy going on a quest specifically for Hestia. He might have to find a special artifact that is related to her. Along the way, he could meet new characters who are also loyal to Hestia. He would face challenges that test his loyalty to Hestia and his understanding of her values. For example, he might have to choose between saving the flame and saving his friends, and his decision would show his growth as a champion of Hestia.
Well, a cool plot might involve Percy being thrust into a situation where he has to mediate between Demeter and another god who has accidentally (or not) damaged one of her main domains. He could be championing Demeter's cause in a sort of divine court. Also, Percy could be involved in a story where he discovers an ancient prophecy related to Demeter that only he can fulfill as her champion, which leads him on a journey filled with mystery and danger.
A great plot for this fanfiction could be Percy being summoned by the spirit of Ouranos himself. Ouranos could give Percy a task to unite all the different factions of demigods, including those who are usually at odds with each other, like the Romans and the Greeks. This would be a huge challenge as there are old grudges and differences in beliefs. Along the way, Percy would have to overcome his own doubts and the mistrust of others. He might also face some magical obstacles that are specifically designed to prevent the unification of the demigods, and he has to use his wits and powers as the Champion of Ouranos to break through them.
One idea could be Percy having to face a series of trials specifically designed by Hera to prove his worth as her champion. For example, he might have to navigate a maze filled with illusions based on Hera's past grudges.
Well, perhaps Percy in the fanfiction is faced with a moral dilemma related to his role as Champion of Styx. For example, he might be asked to make a sacrifice that goes against his principles but is necessary to save the world. Or he could be dealing with the jealousy and suspicion of his friends who don't fully understand his new powers and status. This could lead to some really interesting character development and story arcs.
Well, a plot idea could involve Percy being cursed by the fates to forget his own identity. He then has to go on a journey to rediscover who he is while still fulfilling his duties as the champion of the fates. Along the way, he might meet old friends who don't recognize him at first, and he has to prove himself to them. Or perhaps the fates send Percy on a mission to prevent a prophecy from coming true that would destroy the entire demigod world. This would involve him traveling to different mythological places and facing powerful enemies.
One idea could be Percy having to face off against a new type of mythical creature in the arena that no one has ever seen before. It would be a test of his skills and quick thinking.
One plot idea could be Percy having to face a series of trials in the Underworld to prove himself as the Champion of Erebus. Maybe he has to retrieve a powerful artifact that was lost in the darkest corners of the Underworld, and along the way he encounters old foes and makes new, unexpected allies among the dead. Another idea is that as the Champion, he has to mediate a power struggle between different factions of the Underworld, like the Furies and the shades. This would put his diplomatic skills to the test as much as his combat abilities.
One idea could be Percy having to face a new type of Titan - one that can control time. He'd have to figure out how to break free from the time loops the Titan puts him in. Another could be Percy teaming up with some unlikely allies from the Titan side who have a change of heart and want to stop the more evil Titans. Maybe a Titan who was forced into the fight but doesn't really believe in the cause.
