head and chest straps - DTC Interrogator
body - ROC Destro
legs - ROC SRO Destro

I really wanted the Interrogator helmet and head from the Collectors Club convention set for this custom, but no way would I pay that much to get a figure only to cut up his head and use the helmet only. This is the next best option. I originally wanted to hollow out the helmet but unfortunately, I realized that there was no head that can fit in the helmet. This works ok for me anyways as he'd probably never show his face.
