Rarity & Significance

Common. While Mainframe is a well-known character from the 1986 series and the Sunbow cartoon, he is not considered a rare 'grail' figure. He is significant as a core member of the mid-80s roster during the peak of G.I. Joe's popularity.

Special Features

Includes a sculpted holster on the right leg and detailed tech-readout paint applications on the left sleeve.

Notable Variations

A 'Special Mission' Brazil version (named Glenda-color scheme derivative) and a 2008 25th Anniversary remake exist, but this is the standard 1986 vintage mold.
