|~ Moby Dick|
A "Nemesis" is an opponent or enemy who is created by the actions of a hero within a story or legend.. The name is derived from the Greek goddess of vengeance who would punish people who committed hubris.
A good example of a nemesis would be Grendel's Mother, who fought Beowolf after the hero killed her son.
A nemesis often overlaps with Wrathful and Vengeful, by very definition it is a specific subset of an Archenemy and the opposite of a Provoker.
