While doing some random web browsing, ran across some sites devoted to the awesome 1970s-era Bionic Man toys. One of my favorites had to be this Maskatron figure.
This was based on the android character played by the always excellent John Saxon in the Day of the Robot episode. In that episode, Saxon portrayed both an inventor and the evil robot duplicate designed to replace him.
According to Wikipedia, that episode first aired on February 8, 1974 so I was all of 5 years old when I first saw that–and I remember that episode scared the shit out of me. Part of me suspects that the rest of y’all have been secretly replaced by android duplicates.
The toy itself was awesome–a frigging robot with three interchangeable faces. All of the Six Million Dollar action figures and accessories were awesome, but my 7 or 8-year-old self loved ripping the Oscar Goldman mask off this one to set up an epic front lawn throw down between Lee Majors and a badass robot.
