Cephalus was Zeus' personal huntsman. He was sent by Zeus to bring Hercules from Earth back to Olympus. He was recalled by Zeus after seeing the nobility of the Sub-Mariner who had risked his life for Hercules in battling the Huntsman.
Cephalus was created by Zeus and endowed with a fraction of his power. Zeus gave him immortal skill to track his victims and the power to create terror in the one he stalked. He also had the power to summon mystical creatures as the Sirens or Polyphemus, Scylla and Charybdis.
He was accompanied by his shadow hound, who possessed claws of burning ice.
