Perhaps the fanfiction focuses on Percy leading the armies in a war against an ancient evil that has risen again. He uses his strategic skills and his unique powers to guide the troops. Along the way, he could form new alliances with mythical creatures or even other pantheons. There might also be a sub - plot about his relationships with his friends and how they support him in this huge task.
Well, it could be about Percy facing a new and powerful enemy that threatens Olympus. He might have to gather different demigods from various cabins to form a united army. Maybe there are some internal disputes within the army that he has to resolve as well.
The main characters would include Percy as the leader. But we can't forget about Clarisse. She is a fierce warrior and would be an important part of the armies. Tyson, Percy's Cyclops half - brother, might also be involved, using his strength to fight. And then there are the minor gods and goddesses who could either support or oppose Percy's leadership, adding more drama to the story.
In this fanfiction, perhaps Percy is influenced by some dark force. This force convinces him that the Olympians are corrupt and need to be overthrown. He then betrays them by stealing important artifacts from Olympus that are crucial for its protection. He might also try to turn the demigods against the Olympians.
One possible plot could be that Percy jumps off Olympus in a moment of extreme despair. Maybe he feels betrayed by the gods and their constant manipulation. He jumps, thinking it's an escape, but then discovers he has new powers or a new mission on earth. For example, he might land in a mortal city and realize he has to protect it from a new threat that the gods are ignoring.
It could be about their unique upbringing on Olympus. Maybe they have to deal with the politics among the gods while growing up. For example, Percy might struggle with Poseidon's expectations and his own identity in this divine setting. Jason could be learning about his Roman heritage in a more Greek - influenced environment. And Nico might be trying to find his place among the living and the dead while being raised on Olympus.
Well, one possibility could be that they are given special status on Olympus. Maybe they are tasked with keeping the peace among the gods, which would lead to a lot of interesting interactions with the deities. They might also use their unique powers to improve the living conditions on Olympus, like Percy controlling water to create beautiful fountains or something.
Perhaps in this fanfic, Percy is raised as a sort of prince on Olympus. He could be given tasks by the gods to prove his worthiness to be among them. This might include going on quests that are not just for the safety of the mortal world, but also for the stability of Olympus itself. He would also have to navigate the complex social hierarchies among the various gods and goddesses.
A possible plot twist could be that one of them is actually a secret weapon of an enemy god. For example, Nico could be unknowingly influenced by a dark force that wants to use his powers to bring chaos to Olympus.
One possible plot development could be Percy and his friends facing a new, even more powerful enemy. Maybe an ancient primordial being that was previously sealed away has been awakened. For example, a new Titan or a primordial chaos entity. Another development could be Percy exploring his new powers or abilities that he might have gained after the events of Heroes of Olympus. He could be training other demigods as well, passing on his knowledge and skills.
In such a fanfiction, perhaps Percy could use his unique powers in new and unexpected ways. He might gain the support of some unexpected allies among the demigods or even some minor gods who are tired of the Olympian regime. This could lead to a large - scale battle where Percy's strategic thinking and combat skills are put to the ultimate test against the might of Olympus.
He could be involved in some really cool quests. Like finding some ancient artifact that's hidden deep within Olympus. He'd probably make new friends among the minor gods and goddesses. And of course, there would be the constant threat of some ancient evil trying to take over Olympus, and he'd be right in the middle of the fight to defend it.
