One idea could be Percy having to prove himself to Zeus. Since he's his son in this fanfiction, Zeus might be overly critical. Percy could go on a quest to retrieve a powerful artifact that was once Zeus's but was lost. Another plot could involve Percy's relationships with other demigods changing. They might be jealous or in awe of his new status as Zeus's son.
A possible plot is Percy being sent on a mission by Zeus to a different realm, like the Underworld, but with a task that only someone with his unique heritage can do. He might have to use his powers in new ways, as being the son of Zeus could give him abilities he didn't have before. Along the way, he could meet new creatures and form unexpected alliances, all while trying to figure out what it really means to be Zeus's son.
Well, a great plot idea is Percy getting caught in a power struggle between Zeus and the other gods. Maybe the other gods are worried that Zeus will give Percy too much power and they try to undermine him. Percy has to navigate this political mess while also dealing with his own self - discovery as the son of Zeus. He could also discover some long - lost siblings or family secrets related to Zeus.
A great plot could involve Percy discovering a hidden power within him due to his relation to Zeus. He then has to learn to control it while also dealing with the envy of other demigods. For example, he might accidentally cause some chaos in the camp which makes others suspicious and jealous of his new - found abilities.
A cool plot could be Percy being sent on a quest that involves mending the rift between Zeus and Poseidon. Along the way, he meets old foes and new allies. He has to use his wits and the powers he got from his fathers to convince other gods and demigods to support his cause. For example, he might have to show the children of Zeus and Poseidon that they can work together instead of being rivals.
Well, perhaps in the fanfic, Percy is wrongly accused of a crime by Zeus. He then has to go on the run, all the while trying to clear his name. Along the way, he teams up with some unlikely allies, like a group of nymphs who have their own reasons for helping him. As he's on the run, he uncovers a conspiracy within the Olympian council that could change the fate of the demigod world forever.
One idea could be that Percy discovers a long - lost power that is somehow connected to Zeus, and they have to work together to control it. Maybe it's a power that could either save or destroy the world of the gods. Another could be Percy getting into a situation where he has to prove his worth to Zeus by going on a quest that Zeus deems impossible. And a third could be a situation where Zeus, for some reason, loses his memory and Percy has to protect him while also dealing with the chaos that Zeus's absence causes among the other gods.
Maybe in the fanfiction, Zeus has left a hidden prophecy about his legacy that Percy discovers. This prophecy could involve a great power that is locked away and can only be accessed by following a series of dangerous quests. Percy then has to navigate through various challenges, including dealing with other gods who are either jealous or afraid of what this legacy might bring.
One plot idea could be that fem Percy, with her unique charm, catches Zeus' attention in a way that no one else has. This could lead to a series of secret meetings and a complex relationship that challenges the power dynamics in the Greek mythology world.
One idea could be Percy having to mediate between Zeus and Hades during a major feud. Since he's the son of both in this fanfiction, he has a unique connection to them. He could use his powers and his knowledge of both of their domains to try and broker peace.
Perhaps in the fanfiction, there could be a prophecy that involves Percy, Zeus and Poseidon. The prophecy states that only when the three of them perform a certain ritual together can they prevent a great disaster. But the ritual requires them to put aside their differences and trust each other completely. Percy has to convince the two powerful gods to participate.
One idea could be Percy having to hide his true parentage from the other demigods at Camp Half - Blood. He's constantly worried about being shunned or attacked if they find out. Another could be Percy using some of Medusa's powers in a unique way, like being able to turn enemies to stone briefly but with some unforeseen consequences. Maybe he has to go on a quest to find a way to control these new powers.
One idea could be Percy having to navigate the Underworld politics due to his relation to Hades. He might face challenges from other underworld creatures who don't trust him. Another could be Percy using his newfound powers as the son of Hades to fight against an ancient evil that threatens both the mortal and underworld realms. Or perhaps he has to deal with the stigma of being Hades' son in the demigod community and prove himself worthy.
