Hephaestus is the god of metal working, volcanoes, and sculptors. He is son of Zeus and Hera, he is also married to Aphrodite.
In the 2010 movie, he is merely a background character. Although it can be surmised that he most likely still forged the Lightning Sword.
Hephaestus created along with the aid of the Cyclopes, most if not all of the god's weapons and items. Among his creations, we have:
- Ares' Hammer
- Hades' Pitchfork
- Helmet of Invisibility
- Poseidon's Trident
- Spear of Triam
- Zeus' Thunderbolt
- The Hephaestus appearing in Clash of the Titans is bulky, armored, tall and has a younger appearance than that appearing in Wrath of the Titans.
- In Clash of the Titans Hephaestus is seen along with the other gods on Olympus, while in Wrath of the Titans, Hephaestus states he was casted away and depowered by Zeus many years ago when he sided with Hades, which contradicts his appearance in the 2010 remake.
