The Microchange line was one of the main two lines that the toys from the early Transformers line came from. Microchange is a subset of the Microman lne, which mainly constited of GI Joe- sized figures that were super-posable, and had interchangeable hands. The Microman and Microchange figures were on a 1:1 scale, so the toys were the size of the characters they represented. Many of the Diaclone figures came in multiple color schemes, a number of which were used for the Transformer line.
The Microchange line included the following figures:
- MC-01 Micross. The first version was the blue cassette used for Frenzy. A red version, used for Rumble, came with Cassette Man. Towards the end of the line, a red/blue version was released.
- MC-02 Jaguar. The first version was used for Ravage. A blue version was released at the end of the line, and was used for the e-Hobby figure Howlback
- MC-03 Condor. The first version was uead for Laserbeak. The blue second version was used for the e-hobby figure Garboil. Buzzsaw's deco was created for the Transformers line.
