Hoss Delgado is a spectral exterminator, hunting down monsters like werewolves, and various other supernatural phenomena. Hoss developed a crush on Eris, the goddess of chaos starting in "Guess What’s Coming to Dinner?" They dated for a while, but it had been a dysfunctional relationship, with his dating the goddess of chaos having an adverse effect of creating too much order in the world, which put him out of the monster hunting business, so he broke up with her.
In Underfist: Halloween Bash, he serves as the deuteragonist.
