A ring name is a type of stage name used by an athlete such as a professional wrestler, mixed martial artist, or boxer whose real name is considered unattractive, dull, difficult to pronounce or spell, amusing for the wrong reasons, or projecting the wrong image. Since the advent of the Internet, it is relatively easy to discover a fighter's real name.
