Often, Poseidon is depicted as heartbroken. He may withdraw from his normal duties and just sit in his underwater palace, watching over Percy's lifeless body or the place where he died.

One possible plot could be Poseidon's grief and his journey to seek revenge for Percy's death. He might use his power to disrupt the world that allowed such a thing to happen. Another could be Poseidon trying to bring Percy back to life, going against the rules of the gods and facing many challenges along the way. Or perhaps Poseidon watches as the world changes after Percy's death, seeing how the other demigods step up or fall apart without Percy's leadership.

In Poseidon and Percy gay fanfiction, the authors usually have a lot of freedom to shape the story.

Annabeth would definitely be involved. As Percy's girlfriend, she is often by his side during his adventures.

He might provide some comical relief during the serious moments when Poseidon is showing his pride. Also, other demigods from Camp Half - Blood like Jason, Piper, and Leo could be involved.

He might try to communicate with Percy in gentle, non - verbal ways, like sending small ripples of water to make Percy laugh.

Poseidon, as Percy's father, has a divine power to safeguard Percy in various dangerous situations that Percy often gets into in the Percy Jackson universe.
