In professional wrestling, a heel is a villain character. Heels are portrayed as behaving in an immoral manner, breaking rules or otherwise taking advantage of their opponents outside of the bounds of the rules of the match. In non-wrestling jargon, heels are often the "bad guys" in pro wrestling storylines. They are typically opposed by a babyface or more simply, face (crowd favorite). Some tweeners exhibit heel mannerisms. 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. Many heels today subscribe to the beliefs espoused by Mick Foley in his autobiography, Have a Nice Day!: A Tale of Blood and Sweatsocks - that a heel must always believe that whatever they do is justified and that they are in the right.
