In the development of their relationship, they would also have to deal with family matters. The other gods, like Zeus, might try to interfere. But Poseidon and Hades could stand united. They would have to communicate a lot, about their pasts, their fears, and their hopes for the future. Through these deep conversations, they would form an unbreakable bond. Their marriage would be more than just a union of two powerful gods, but a relationship based on mutual respect, love, and the shared goal of creating a new order in the mythological world.
Well, it could focus on the political implications. In Greek mythology, the gods often have power struggles. Their marriage could be a strategic move. Poseidon and Hades might join forces to gain more influence among the other gods. Maybe Zeus would be threatened by their union. This could lead to a series of events where they have to prove their loyalty to each other and their new combined rule while facing opposition from Zeus and his allies.
To develop Poseidon's character, focus on his connection to the sea. Describe how his moods are like the changing tides. For example, when he's angry, the seas rage. Show his pride in ruling the oceans. For Hades, emphasize his loneliness in the underworld. Maybe he has a longing for something more than just ruling the dead, like a connection to the living world which he can't fully have.
Their relationship can be portrayed as a complex one. They are brothers, so there is an underlying bond of family. However, they also rule very different realms. For example, Hades might be jealous of Poseidon's more 'visible' and vast realm of the sea. At the same time, Poseidon could be envious of Hades' power over life and death in a way. But they also rely on each other in some ways, like when there are threats that could affect both their domains.
Their relationship would likely start with Poseidon being a strict but loving father. He would teach Percy the ways of the sea and the power that comes with being a son of Poseidon. As Percy grows, they might have some disagreements, for example, about how Percy should use his powers in the mortal world.
First, they need to have shared experiences. For example, if the OC is a fisherman's daughter, they could bond over their love for the sea and its creatures. Second, communication is key. Poseidon might have to learn to understand the OC's mortal way of thinking and speaking. Third, there should be obstacles. Maybe other gods disapprove of their relationship, which makes them fight for each other and grow closer.
As 'lemon' fanfiction is not something that should be promoted, we can look at normal Hades and Poseidon fanfiction themes. These may include their part in the creation and governance of the world, and how their personalities clash or complement each other in various mythological events.
Power dynamics is a common theme. Given that both Poseidon and Hades are powerful gods, how their powers interact in the context of a relationship can be explored. For example, one might write about how they use their powers to protect or impress each other.
One great fanfiction idea could be a story where Zeus, Poseidon and Hades have to team up to face a common threat that is even more powerful than them. Maybe a primordial being awakens and they must put aside their differences. In this story, Percy could be the mediator between them, using his unique position as the son of Poseidon to try and keep the peace among the three powerful gods.
Perhaps it begins with a misunderstanding. Fem Harry could be mistaken for someone else in Hades' realm. Hades, being a powerful and somewhat solitary figure, might be initially hostile. But as he discovers her true identity and her own unique story, his attitude changes. Their relationship could develop as they both realize they have common enemies or goals. For example, they might both be fighting against a greater evil that threatens both the wizarding world and the underworld. This shared purpose could bring them closer together, and eventually, they could become mates.
Their relationship would likely become much closer. Percy would start to see Poseidon as not just a powerful god but also as a father. Poseidon, in turn, would get to know Percy better and might start to teach him more about their family's history.
