It's weird, because the first wave (Primal, Megatron, Rattrap & Cheetor) all had fairly obvious deco differences. I personally grabbed Cheetor just to have another eye-color variant, and I was tempted to go for Megatron because of the darker purple (but couldn't justify spending 2.5x the original price!) But then the later waves appear to be just straight up reproductions of the originals. (Though having Tigatron be the Japanese version was a nice surprise.)
