Oh, you created make-up for people!  Nah, I used the Silly Putty on the model kit of Steve Austin, basically staging the assembled figurine with a bare leg and arm by omitting the removable sleeve and pants leg pieces, and building up the putty.

And yes, I had the 12 inch action figure.  It had a push button mounted on the back that when repeatedly pressed, provided a "rachet" action for the bionic arm, allowing it to lift a plastic "engine block".  The doll also had a "fish-eye" peephole lens running through the head, serving as his bionic eye.

I had the first release of the doll and so I was somewhat disappointed with the bionic detailing.  It consisted of two clear acrylic pieces with simple decal backings one fitted within the arm.  One could reveal them by rolling up a surface hugging, skin colored sheath of elastic.  Years later I realized that element was basically an opaque condom!  Later editions of the figure had an arm and legs that were hollow and possessed physical "hardware" like frames, pistons and gears.  One could reveal these details by removing flush mounted "access panels".  (My dad wouldn't let me get one of these improved versions as it was rather more expensive and I already had one.

I also owned "Mask-atron", the android duplicate based upon the John Saxon character from one of the more popular episodes.  Like the first edition Steve Austin, it too just had clear acrylic wedges with "bionic decals".  But it came with 3 swappable faces, John Saxon's, Lee Majors' and Richard Anderson's (Oscar Goldman).  Saxon's big reveal as a robot was likely inspired by the movie "WestWorld" with Yul Brynner playing a robotic cowboy.  In a repair sequence, Brynner's face is removed to show wires and circuit boards.  The Six Million Dollar Man paid homage by having Steve literally punch Saxon's "face" to the ground.  Thus the toy had removable faces.  To increase play value, it also came with swappable forearms.  One could remove the "human" limbs at the elbow joints and replace them with, get this, a claw-like shovel and a suction cup mounted upon an extended rod.  Looking back, that second attachment was effectively a Dalek's plunger arm!

Actually, I liked the features of the "Fembots" from the "Bionic Woman" line better.  Only the "face" region detached instead of the entire front half of the head as with "Mask-atron", and when removed, robotic eyes and a speaker element was revealed, closer to the motif depicted in the episodes.  But my dad was not about to let me get a "Barbie" doll...bloody gender stereotypes.

Ah, childhood memories!

Sincerely,

Bill
