Micromasters is a Transformers subline composed of small figures that came packaged in groups and with bases that interacted with the figures. They were sold at the peak of Galoob's Micro Machines craze and were packaged in groups of four just like Micro Machines. The Micromaster Combiners sub-line was made with a similar gimmick to rival Matchbox's Connectables line.
