Dubrovnik (right) and Balinkoff.

KAOS agent, henchman to Siegfried.

Dubrovnik and a fellow agent, Balinkoff, are summarily executed by Siegfried for "stupidity" after failing to prevent Maxwell Smart from escaping a supposedly escape-proof dungeon.

Portrayed by Larry Barton [Episode #63: "The Spy Who Met Himself"].

Reality Check: Dubrovnik is the name of a city in Croatia which, at the time the episode was filmed, was part of Yugoslavia.
