Hephaestus is a fictional character in Marvel Comics. He first appeared in Thor #129 (June 1966), and was adapted from mythology by Stan Lee and Jack Kirby.
The character subsequently appeared in Thor #131 (August 1966), Thor Annual #5 (1976), The Avengers #281 (July 1987), #283-284 (September–October 1987), and Hercules #4 (September 2005).
Hephaestus is the weaponmaker of the Olympian pantheon. He is not to be confused with the Eternal Phastos.
Zeus is his father, Hera is his mother, Ares and Hebe are his siblings, and Aphrodite is his former wife.
Apollo, Artemis, and Hephaestus appear in a meeting with Hera and Pluto, where Hera reveals her plans to them. In the assault on the Contiuum, he makes weapons for Hera. He drops Hercules and Cho into different chambers and says the only way to escape is by pressing a button which will kill them but free the other. This is thwarted when the two press the button at the same time.
Immortal and possessing superhuman physical attributes similar to those of the other Olympians, Hephaestus is a master weapons maker and inventor, able to make weapons which could kill even Hercules, but lacks the ability to project any form of energy, mystical or non-mystical. He made Hercules's mace, Ares' armor, and Zeus' chariot.
Hephaestus appeared as part of the "Olympian Gods" entry in the Official Handbook of the Marvel Universe Deluxe Edition #9.
