CG Robo was one of the lesser-known facets of Machine Robo, a 1993 attempt to revive the line five years after its' initial demise. These were medium-sized figures (typically around 5" tall in robot mode) with light & sound effects ('CG' stood for 'Change and Glow'). The line lasted for one year and fourteen figures before cancellation.

Five came out in Europe as part of the Robo Machines reissue-slash-revival line, a similar failure in Europe. For simplicity's sake (i.e. to avoid the CG Robo index consisting of Dozer CG), the European releases have been bundled into this section.
