One interesting storyline could be Percy having to face Thanatos in a life - or - death situation in a way that defies the normal rules. Maybe Thanatos is being controlled by an outside force and Percy has to free him. Another could be a slash - themed story where Percy and another character develop an unexpected bond while dealing with Thanatos' presence in the background. For example, Percy and Nico might have a deeper connection form as they both have had interactions with Thanatos and they work together to stop a threat related to the god of death.
Thanatos can add an element of danger and mystery. In slash fanfiction, he could be a catalyst for the relationship between two characters.
