Well, one way to re - imagine their relationship is to make it more of a partnership. In the original myths, Persephone is often seen as a victim of Hades' abduction. But in fanfiction, we could see them as two powerful deities who came together by choice. They could be equal partners in ruling the Underworld, with Hades respecting Persephone's opinions and decisions more.
There might be a fanfiction where Persephone uses her powers to help Percy Jackson understand some of the deeper mysteries of the Greek world in the context of the Percy Jackson universe. This could involve her connection to Hades and how that affects the balance of power. For example, she could show Percy how to navigate certain dark areas that are related to Hades' domain.
One plot idea could be Percy having to mediate a dispute between Hades and Persephone. Maybe something has gone wrong in the Underworld and their relationship is on the rocks because of it. Percy, being the hero he is, tries to find a solution that satisfies both of them.
One way to develop the storyline could be to explore Percy's struggle with his new identity. Since Hades and Persephone are such complex deities, Percy might have a darker side to him. He could struggle with controlling powers related to the Underworld, like shadow manipulation or communicating with the dead. For example, in a school setting, he might accidentally let out some spooky manifestations when he's stressed.
In the original myth, Hades abducts Persephone. But in Percy Jackson fanfiction, it could be a more consensual relationship from the start. For example, they might be presented as having a pre - existing connection that was not part of the traditional myth.
A major theme could be identity. Percy has to come to terms with being the son of two very powerful and different deities. It's not like being the son of Poseidon where he has a more straightforward heroic image. Here, he has to figure out who he really is.
One interesting interpretation could be that the kidnapping is not as malicious as it seems in the original myths. Maybe Hades is desperate to have Persephone in his realm because he truly loves her and sees no other way to be with her. He might be trying to show her a world she's never known before, a world that has its own beauty beneath the surface.
They would become closer. The shared experience of expecting a child would strengthen their bond. Hades would be more protective of Persephone, and Persephone would rely on Hades more for emotional support.
She can be portrayed as a mysterious and alluring character. Her relationship with Hades often plays a part in the fanfiction. In some stories, she may be jealous of Percy's interactions with the Underworld, while in others she might be an ally, guiding him through the dangerous and shadowy realm. Fanfic writers may also explore her dual nature as the Queen of the Underworld and the daughter of Demeter, with her being torn between her two 'homes' in a sense.
In fanfiction, Percy Jackson as the champion of Hades could bring a whole new dynamic. He might have to deal with the darker aspects of the Underworld. For example, he could be in charge of ensuring the souls are properly sorted, which is a huge responsibility.
