Can you describe "destron"?

"Destron" is the japanese word for "Decepticon" ... "Cybertrons" are "Autobots".

That's why you see TF's numbered like this:
D-22 Starscream
C-372 Starconvoy

the C stands for Cybertron or Autobot.

The D-22 is a Takara reissue along the lines of Starconvoy, and the S-16 Special Megatron.
