Perhaps in a fanfiction, there could be a magical curse that causes Athena to become pregnant by Poseidon. This could lead to a power struggle among the gods as they fear the implications of a child born from such a union. The story could then focus on how Poseidon and Athena try to protect their unborn child from the scheming of other deities. They might have to seek help from unlikely allies and face numerous challenges along the way.
A possible plot could be that Poseidon and Athena are in a secret relationship in the realm of the gods. When Athena discovers she is pregnant, they must decide whether to reveal their relationship to the other gods. The fanfiction could explore their internal struggles, with Poseidon being more impulsive and wanting to announce it, while Athena is more cautious, fearing the political and social ramifications among the divine hierarchy.
One plot idea could be a story where Poseidon and Athena have to team up to face a common threat to the pantheon. Maybe a new and powerful deity emerges who wants to overthrow the existing order. Their different powers and personalities would create interesting dynamics as they try to work together.
A great plot could be Percy getting caught in a power struggle between Athena and Poseidon's followers. Since he is the son of both, he is a symbol of unity or a threat, depending on how different groups view him. He could be forced to prove his loyalty to both sides while also trying to maintain peace among them. This could involve battles, political intrigue, and lots of character development as he tries to figure out where he truly belongs in this complex world of gods and their followers.
Perhaps in a fanfiction, the kiss could be a part of a peace - making gesture. There has always been a rivalry between Poseidon and Athena in Greek mythology. So, the kiss might be a strategic move in a time of great unrest among the gods. It could be a way to show unity in the face of a common enemy. And from this kiss, a new alliance could form, changing the power dynamics among the deities.
Poseidon might become more protective. Usually a powerful and sometimes brash god, with Athena pregnant, he could become more cautious and less likely to engage in his usual power plays. He would be focused on safeguarding Athena and the unborn child.
One possible plot could be a story of cooperation. Maybe there is a great threat to the world of the Greek gods, and Athena, with her wisdom, and Poseidon, with his power over the sea, have to work together. They could start off distrusting each other due to their past rivalries, like the competition for Athens. But as they face challenges, they gradually learn to respect and rely on one another's strengths.
Well, a plot might involve a love triangle where Poseidon and Athena both fall in love with a mortal. Their rivalry for the mortal's love then turns into an understanding of their own feelings for each other. Or perhaps there's a story where they are trapped in a magical realm and have to rely on each other for survival, and in the process, their love story unfolds.
One idea could be that Percy has to seek Athena's wisdom to solve a complex mystery in the mortal world that is somehow related to the gods' ancient secrets. Maybe it involves a powerful artifact that was lost long ago and only Athena's knowledge can lead Percy to it.
One plot idea could be that the OC is a young mermaid who accidentally crosses into Poseidon's territory. Poseidon, initially angry, is intrigued by her courage. Another could be the OC is a mortal with a special power to control water to a small extent, and Poseidon takes an interest in mentoring the OC. Or perhaps the OC is a demigod sent on a quest by the gods, and Poseidon has to decide whether to help or hinder the OC.
One plot idea could be Percy having to go on a quest specifically guided by Poseidon's hidden messages in the sea currents. He has to decipher these messages to find a lost artifact that can save the underwater kingdom from a new, mysterious threat.
One plot idea could be that Hades and Poseidon have to team up to face a new, powerful threat from the underworld that is starting to seep into the seas. They have to combine their powers, Hades' control over the dead and the underworld, and Poseidon's mastery of the seas. Another could be a story about their childhood, how they supported each other during the early days in Olympus when they were often overshadowed by Zeus. Maybe they shared a secret adventure that no one else knew about.
