Dirty Wrestler
In professional wrestling, a heel (also known as a rudo in Lucha libre) is a villain character. In non-wrestling jargon, heels are the "bad guys" in professional wrestling storylines. They are typically opposed by a Babyface or more simply, face (crowd favorite). Some tweeners (not explicitly regarded as good or bad) exhibit heel mannerisms. Heels are often portrayed as behaving in an immoral manner, breaking rules or otherwise taking advantage of their opponents outside the bounds of the rules of the match. Others do not (or rarely) break rules, but exhibit unlikeable personality traits . No matter the type of heel, the most important job is that of the antagonist role. Heels exist to provide a foil to the face wrestlers. If a given heel is cheered over the face, a promoter may opt to turn that heel to face, or to make the wrestler do something even more despicable to encourage heel heat.
History
The term "heel" is most likely derived from a slang usage of the word that first appeared around 1914, meaning "contemptible person". Common heel behavior includes cheating to win (e.g., using the ropes for leverage while pinning or attacking with foreign objects while the referee is looking away), attacking other wrestlers backstage, interfering with other wrestlers' matches, insulting the fans (referred to as cheap heat), and acting in a haughty or superior manner.
Once in a while, faces who have recently turned from being heels will still exhibit some heel characteristics. For example, Kurt Angle, even after turning face for his feud with Mark Henry, used a steel chair, an exposed steel ring peg, and leverage from the ropes during his pin to secure his victory at the Royal Rumble 2006. John Cena, after his initial face turn, often used a steel chain to win some of his matches, such as the one against the Big Show at WrestleMania XX. Finlay is also another example after his face turn as he continues to use his signature shillelagh to win matches illegally. Also certain wrestlers, such as Ric Flair or Eddie Guerrero, gained popularity as faces by using heel tactics.
