Mr. Hercules.
Scrawny, bespectacled KAOS agent who orders Maxwell Smart poisoned and arranges a trail of clues timed so that Max arrives at his office just before the poison takes effect.
Mr. Hercules owns a gymnasium, is a health food nut and enjoys watching people die as a contrast to his own "splendid health".
Portrayed by John Fiedler [Episode #72: "Classification: Dead"].
