Hephaestus, known as Vulcan in Roman mythology, was the god of fire, especially the blacksmith's fire, as well as the god of volcanoes. He was the master forger for the gods, and created the thunderbolts that Zeus threw whenever he was angry. Hephaestus, like Ares, was the son of Zeus and Hera. This episode's depiction of Hephaestus closely matches the classical description; lame and deformed. However, Hephaestus here is more congenial towards Ares than the Greek myths have often portrayed the two.
