The big daddy tron of the Micronauts line was Biotron, and no toy line that features battery powered toys and was based on that same line would be complete without it's own, so the Inter-changeables followed suit. The big daddy tron of the IC line was Cosmobot.

The two trons were basically identical, but the biggest difference was of course the new garish color scheme. Gone were the primary red, white and blue to be replaced by yellow, red and...pink? Cosmobot and Biotron carried all the same basic accessories and functions. The 8 adapters included were used to help make the head and arms spin and rotate like the original could, and the only extra pieces missing were the 2 small wheels.

 
 
 
 

Operating on 2 C batteries, Cosmobot could perform all the same motorized tricks the original could like the rolling tank mode.


  


But the cheaper grade of plastic used led to loose fitting and fragile parts, a common feature in the IC line.

 
Cosmobot also came with Inter-changeables versions instruction and sticker sheets, which were basically altered Micronauts sheets. Also any kind of copyright or company info was removed from the figures body, and any kind of release date or year indication on the packaging was nonexistent…even further deepening the mystery of the exact origins of the toys altogether. The Micronology below shows Cosmobot clocking in as the 6th variation on the same figure.
