Definition: Vax03: In Greek mythology, the mortal hunter was originally the god Vapax, son of Hephaestus and Icarus. He became a monster named Vax for his constant killing of humans. Over time, he transformed into a vulture-like bird that roamed the night sky and attacked unsuspecting mortals. This vulture became the name of the bird that bears the same name as the word 'vax' in Greek mythology: Vax03.
