A man who is adept at various forms of martial arts, most notably Shotokan Karate, Kyokushin Karate, Shorinji Kenpo, Kajukenbo, Judo, Kali, Wing Chun, Jeet Kun Do, or Aikido. They never indulge in drinking alcoholic beverages, but hang around the area in a secret, undisclosed location. The moment a barfight erupts, they jump in screaming very loudly, clad in some sort of martial arts uniform such as a gi, and proceed to clean the bar.
