In this fanfic, the character development of Female Percy could be amazing. She would grow up in a much different environment compared to the male Percy we know. There could be a lot of internal conflict as she tries to figure out her place in the world of the gods and demigods. Her loyalty might be tested, and she could end up being a key figure in a big battle, using her Underworld - influenced powers to turn the tide.
The story might focus on her struggle to fit in with the other demigods. Since she was raised by Hades, they might be suspicious or even afraid of her. But she could prove herself to be a hero in her own right. She could also have a unique relationship with the other children of the Big Three (Zeus and Poseidon).
One possible plot twist could be that she discovers she has a different parentage than she thought. Maybe Hades isn't really her father, but someone else who had a reason to leave her with Hades. Another twist could be that she has to fight against Hades at some point, even though he raised her.
One possible plot twist could be that Percy has a different set of powers. Since Hades is the god of the underworld, Percy might have an affinity for shadow manipulation or communicating with the dead in a more in - depth way than in the original stories. For example, he could be able to summon undead warriors to fight for him.
In this fanfic, perhaps Percy is the one in need of protection. Orion and Theseus could be like his guardians. Orion, being a great hunter, might be on the lookout for any threats approaching Percy. Theseus, with his heroic background, could be teaching Percy how to be a better fighter and strategist. They might face off against mythical monsters like the Minotaur or some new, made - up creatures.
Well, it could involve Percy going on a quest specifically for Hades. Maybe he has to retrieve something from the Underworld that only he can do as the so - called 'Champion of Hades'.
Well, it could involve Percy going on a quest in Mars' domain. Maybe he has to retrieve some powerful weapon that was lost there. It could also include him facing off against Mars' enemies or creatures specific to that realm.
In this fanfic, Percy's identity could be in flux. Being adopted by Aphrodite, he may start to question his own self - worth outside of his heroic deeds. His new 'family' might introduce him to a more hedonistic lifestyle. He could be dragged into Aphrodite's schemes to make the world more 'beautiful' in her eyes, which could lead to him having to face off against other gods or monsters who oppose her ideas. His journey would likely be full of self - discovery as he figures out how to be Percy Jackson while also being part of Aphrodite's world.
It could entail Percy being in a strange place, like a new realm in the demigod world. His loneliness would be palpable as he tries to figure out how to get back. His power, say his water - controlling abilities, might be fluctuating in this new environment, making him feel even more lost. He might start to doubt himself and his place among the demigods.
Well, it could be that Percy is raised by a specific god like Poseidon but in a more direct and involved way. Maybe the god teaches him all kinds of super - secret powers and knowledge that normal demigods don't get. For example, he might be taught how to control water in ways that are far beyond what he learned at Camp Half - Blood. This could lead to him having a whole new set of adventures, facing different kinds of monsters and challenges that are related to the god's domain.
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.
The fanfiction might explore Percy's relationships in a new light. For example, his relationship with Annabeth could be strained as he now has loyalties to Gaea. His friendships with other demigods might also change drastically. Maybe he'd be seen as a threat and have to fight against his former allies. Overall, it would be a complete upheaval of the original Percy Jackson story dynamics.
