Battery powered toys are always a great addition to any toy line, and just like the original Mego Micronauts, the Inter-changeables had a few too. One of the old favorites was Microtron, and this line had the C.A.R.P.; "The Cosmic Android Robot Probe".

The two trons were basically identical, but the biggest difference was of course the new, and rather odd, color scheme. C.A.R.P. and Microtron carried all the same basic accessories and functions. Operating on 2 AA batteries, C.A.R.P. could perform all the same motorized tricks the original could.

 
 
 
 

The cheaper grade of plastic used led to loose fitting parts, a common feature in the IC line. Be that as it may, C.A.R.P. was a kind of opposite color scheme to Microtron, and the mixing and matching of parts can create many new and interesting variations.


  

 
 
 
As was a common occurrence with the Inter-changeables, sometimes different parts of the toys pictured on the box would be cast in a different color than the actual toy inside; note the C.A.R.P.'s alternate head color above. C.A.R.P. 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 C.A.R.P. clocking in as the 5th variation on the same figure.
