Villain
Evil character or person
A villain (feminine: villainess) is a real person or fictional character who is defined as a cruelly malicious person involved in or devoted to wickedness or crime; or a character in a play, novel, or the like, who constitutes an important evil agency in the plot". The antonym of a villain is a hero. The villain's structural purpose is to serve as the opposite to the hero character, and their motives or evil actions drive a plot along.
