antagonist
noun
called also antagonistic muscle
Did you know?
On the stage or screen, in a story or a novel, the protagonist is the main character and the antagonist is the opposing one. Pro- and ant- usually mark the good and bad characters, but not always; there may occasionally be an evil protagonist and a good antagonist. In the drama of the real world, it's especially hard to sort out which is which, so we usually speak of both parties to a conflict as antagonists. During a strike, for example, representatives of labor and management become antagonists; they often manage to antagonize each other, and the antagonism often remains after the strike is over.
