This is a mug shaped like a Klingon, a warrior race alien from the science fiction Star Trek original series. The well-statured Klingon race has a genetic predisposition to hostility and a well-known streak of fatalism. This mug is one in a set of six mugs including Captain Kirk, Dr. McCoy, a Gorn, a Klingon, Mr. Spock, and a Mugato.
