A Hero (Greek ), in Greek mythology and folklore, was originally a demi-god, the offspring of a mortal and a deity. Later, hero (male) and heroine (female) came to refer to characters that, in the face of danger and adversity or from a position of weakness, display courage and the will for self-sacrifice, that is, heroism, for some greater good, originally of  martial courage or excellence but extended to more general moral excellence.
