most televised genres. Some of the earliest usages were in fact in westerns. Two episodes entitled Deadly Image appeared within a year of each other on two different westerns. Maverick's version appeared in March 1961, followed swiftly by The Rifleman's take in February 1962. Beyond the coincidence of name, both offered similar plots: the hero becomes confused with a look-alike criminal, and the guilt of the hero must be cleared by demonstrating that the evil twin is a separate individual. Pretty Little Liars could be used as an example, where one of the main protagonists Spencer Hastings was discovered to have an evil identical twin sister named Alex Drake, who had been stalking Spencer and her friends under the identity of "A.D." for years.

The presence of a goatee on a familiar character is now seen as an immediate clue that the character is an evil twin. Even writers not discussing evil twins in their literary sense have occasionally made reference to the goatee through quick metaphor: The Evil Overlord List refers to it with Item 35: "I will not grow a goatee. In the old days they made you look diabolic. Now they just make you look like a disaffected member of Generation X." General usage Type of doppelgänger In modern use, evil twin and one sense of the word doppelgänger have come to be virtually interchangeable. While "evil twin" does not connote the sense of "supernatural harbinger of death", it can be used to mean "a physical copy of one's self who has an altered morality". As metaphor The term evil twin has also passed
