What is the definition of a Classical Hero?

Answer 1

in Greek mythology and folklore, was originally ademigod, their cult being one of the most distinctive features of ancient Greek religion.[1] Later, hero (male) and heroine (female) came to refer to characters who, 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.

Stories of heroism may serve as moral examples. In classical antiquity, hero cults - veneration of deified heroes such as Heracles, Perseus, and Achilles - played an important role in Ancient Greek religion. Politicians, ancient and modern, have employed hero worship for their own apotheosis (i.e., cult of personality).
