Archenemy

The term archenemy refers to an enemy of a character, a superhero or a supervillain, who is seen to be their primary enemy or most worthy opponent. The term doesn't apply to ALL of their enemies though. As an example, Mr. Freeze is an enemy of Batman, but he isn't Batman's chief adversary, because the Joker is by far his most worthy foe.
