What are some interesting plot ideas for 'percy is secretly a god fanfiction'?

One idea could be that Percy, as a girl, has to deal with different expectations in the demigod world. For example, some might assume she's not as strong physically, but she proves them wrong by outperforming many male demigods in combat training. Another plot could involve her having a different kind of relationship with Annabeth. Instead of the typical male - female friendship - romance dynamic, they could have a more sisterly bond that still has elements of competitiveness and deep mutual respect.

Maybe a story where Hestia and God Percy team up to bring back an old, lost magic that once thrived in the world of the gods but has been forgotten. They go on a journey through different realms and face various challenges along the way.

One idea could be that Percy is raised by Poseidon. He grows up with a deep understanding of the sea and its powers from an early age. This might lead to him having a more solitary childhood as he has to hide his connection to the god. Another plot could involve Percy being raised by Athena. He would then be extremely intelligent and strategic, perhaps getting into trouble at school for being too smart. A third idea is if he's raised by Apollo. He could have a natural talent for music and healing, and his adventures might revolve around using these gifts in a world that is both dangerous and full of mythical creatures.

Maybe Percy has to deal with other gods being jealous or threatened by his sudden ascension to godhood. He could face challenges from them to prove he's worthy of being a god. This would involve epic battles and political intrigue in the world of the gods.

A plot could involve Percy getting god - like powers temporarily and having to use them to fix a major problem in the mortal world that the gods are ignoring. For instance, a strange magical plague is spreading that only his new - found powers can stop. He then has to struggle with the idea of whether he should keep these powers or give them up. Or perhaps Percy discovers a hidden part of his heritage that makes him more than just a demigod, something that puts him on a level closer to the gods. This could lead to a conflict with the existing gods who might see him as a threat.

Perhaps in the fanfiction, the Elder Gods start to interfere with the modern world of demigods more directly. Percy and his friends notice strange phenomena, like the weather going haywire and magic behaving erratically. They soon find out it's because an Elder God is trying to regain its former power and is using the chaos to break through the barriers that keep it in a weakened state. Percy then has to find a way to stop it by using his unique connection to water and the help of his father, Poseidon.

One idea could be Percy having to face a new type of demon that is immune to water, his usual weapon. So he has to find a new way to fight. Another could be Percy being tricked into serving the God of Demons for a while and then realizing his mistake and trying to break free.

One idea could be exploring a new adventure where Percy has to team up with a minor god that has been forgotten. They could go on a quest to regain the forgotten god's power and status in the pantheon.

Perhaps Percy, as the God of Wisdom, has to deal with a situation where his wisdom is being questioned by the other gods. They don't believe that a former hero like him can handle the responsibilities of wisdom. So he has to prove himself by solving a complex problem that has been plaguing Olympus for centuries. He uses his unique perspective as a demigod - turned - god to come up with a solution that no one else could think of.

One idea could be Percy having to prove his divinity in a new way. Maybe he has to face a trial set by the gods where he can't use his usual powers but has to rely on his wits and faith. Another could be Percy interacting with a different pantheon's deities who mistake him for one of their own sons of god. He'd have to navigate their culture and rules.
