Yoneya’s wind-up Mego Man stands 7 inches tall and features smooth cruising action, swinging arms, and a distinctive ringing bell nestled within its chest. Its stature belies its intricate design, and inspired toy company Ideal to develop its own iteration known as Mr. Machine during the 1960s to 1970s. Mego Man features spinning wheels, moving arms, and an opening and-closing mouth, all driven by a built-in key mechanism. It was available in red and gray head color variations.

Following the success of the Mego Man, a larger and exceedingly rare successor emerged: the Electro Man. Towering at 10 inches and powered by batteries, this elusive variant expanded upon its predecessor’s legacy with enhanced capabilities, although very few are known to exist.
