In Latin America and English-speaking countries, most wrestlers (and other on-stage performers) portray character roles, sometimes with personalities wildly different from their own. These personalities are a gimmick intended to heighten interest in a wrestler without regard to athletic ability. Some can be unrealistic and cartoon-like (such as Doink the Clown), while others carry more verisimilitude and can be seen as exaggerated versions of the performer's real life personality (such as Chris Jericho, The Rock, John Cena, Stone Cold Steve Austin, and CM Punk). In lucha libre, many characters wear masks, adopting a secret identity akin to a superhero, a near-sacred tradition.

What do most wrestlers do, as far as how they act?
