Along the way, he has to struggle with the moral implications of his power and how it affects his relationships.

This could lead to him having a whole new set of adventures, facing different kinds of monsters and challenges that are related to the god's domain.

Well, one possible plot could be that Percy discovers a hidden realm where dinosaurs still exist. And he has to use his demigod powers to communicate with them.

In this fanfiction, Percy could be tricked into becoming the God of Elements by a devious character. As the God of Elements, he finds himself in a world full of chaos. The elements are out of balance, and he has to figure out how to restore that balance. Along the way, he meets new allies who teach him about the deeper aspects of each element. He also has to deal with the fact that some of the other gods are jealous of his newfound power and try to undermine him at every turn.
