Hephaestus

Hephaestus, the god of fire and the forge is the son of Hera. Hera banished Hephaestus from Olympus when he was born since he was disfigured or scarred on the left side of his face. However, Hephaestus was still the craftsman of the gods. He designed and built many un-beatable weapons for the deities and their heroes.
