Another plot could be Percy discovering a long - lost relative among the children of Hades. This relative has some sort of power or knowledge that could change Percy's understanding of his own identity and his place in the demigod world. It could lead to a journey of self - discovery for Percy as he navigates this new family connection within the dark and often misunderstood realm of Hades.

One idea could be Percy having to use his charm powers (from being Aphrodite's son) to charm a powerful, ancient monster into sparing a group of demigods. He might struggle with the morality of using such powers in this way.

One idea could be Percy using Wolverine's healing factor during a particularly tough battle in the world of Greek mythology. Maybe he gets injured by a powerful monster and the unexpected emergence of the healing ability saves him and surprises his friends.

Maybe they compete to see who can get more demigods to attend their party, and in the process, they learn more about each other's powers.

Perhaps Percy finds out that being the son of Selene gives him a connection to the dreams of mortals. He starts to have strange visions through their dreams and realizes that there is a hidden threat that is using the dreams to manipulate people.
