Hercules is an experiment of Zeus'--a type of mortal hero who can survive to champion the gods in their battle with the Titans. From his mid-teens, Hercules proves that Zeus knew what he was doing. Hercules lacks heroic stature, but he has street smarts, along with magical strength and magical invulnerability. He progresses through his various labors and other adventures over the years, with Saberhagen sometimes interestingly varying some of them.
