Archenemy


An archenemy is the main enemy of someone. In fiction, it is a character who is the hero's or protagonist's most prominent and worst enemy.

Etymology

The word archenemy or arch-enemy originated around the mid-16th century, from the words arch- and enemy.
An archenemy may also be referred to as an archrival, archfoe, archvillain, or archnemesis. However, an archenemy may also be distinguished from a nemesis, with the latter being an enemy whom the hero cannot defeat, even while not being a longstanding or consistent enemy to the hero.
