"Mad, am I?" - Dr. Zharko.KAOS's "mad scientist" who, with his assistant Bruce, operates out of a secret laboratory hidden in a cave on a small island just off the coast of Newfoundland, experimenting on bodies supplied by the morgue attendant Obler.
Dr. Zharko's greatest achievement was the discovery of a means of bringing the dead back to life which he verified by being arrested and executed by the Transylvanian Highway Patrol.
He had planned to next place the living in a state of suspended animation for a period of five years using CONTROL agents Maxwell Smart and 99 as his guinea pigs. However, Max and 99 escape his clutches and Max destroys Zharko and his lab with a well-thrown vial of nitroglycerine, lamenting "If only he had used his genius for niceness instead of evil".
