Archenemy
Main enemy of someone From Wikipedia, the free encyclopedia
In literature, an archenemy, (sometimes spelled as arch-enemy) or nemesis is the main enemy of the protagonist — or sometimes, one of the other main characters — appearing as the most prominent and most-known enemy of the hero.[1][2][3]

Etymology
The word archenemy originated around the mid-16th century, from the words arch-[3] (from Greek ἄρχω archo meaning 'to lead') and enemy.[1]
An archenemy may also be referred to as an archrival,[4] archfoe,[5] archvillain,[6] or archnemesis,[7] but an archenemy may also be distinguished from an archnemesis, with the latter being an enemy whom the hero cannot defeat (or who defeats the hero), even while not being a longstanding or consistent enemy to the hero.[8]
The archenemy should not be confused with the proper meaning of Nemesis — the Greek goddess of justice, retribution, and vengeance — who delivered divine punishment on those who committed great offences against the gods and the world.[9]
