Features the first use of the iconic "na-na-na-na" sound, usually associated with bionic Steve Austin, during his tennis game but only for his bionic eye and not his bionic limbs.
This was the first episode to feature another cyborg character that represented the opposition.
Bionic sound effects were used for Fred Sloan's arm, and Steve Austin's eye during the tennis game.
The Illusion of the Stainless Steel Lady (1974) had this show beat by a full month! Its production was first to bring the concept of human-robots ("fembots") to television. The face is peeled back in the same way, and only the eyes and steel face remain. This show slightly altered the face reveal to make it look like the inside of a computer.
