Hephaestus, also known as Vulcan, is a god.
The ugly and not-particularly-intelligent Hephaestus, or Vulcan to the Romans, is the Greco-Roman God of Smithing and Volcanos. He creates the weapons of the other Gods (particularly Zeus's lightning bolts). Hephaestus is married to beautiful Aphrodite, the Goddess of Love, and is a rather jealous husband. Like all Gods, Hephaestus can shift between a number of different forms.
Behind the scenes
Based on the mythological figure, Hephaestus was first seen in 1940 in the Pastoral Symphony segment of Fantasia.
