All parts - HISS Driver
Submachine gun - Firefly
The Crimson Guard first appeared in comic form in issue #37. It's pretty clear that the penciller did not have an actual CG for reference, since they're drawn to resemble HISS Drivers with a few slight colouration differences. So this was an easy custom to make. Just take a HISS Driver and paint his facemask, chest plate, upper legs and knee pads red, and his gloves grey. Kit him out with a Firefly gun and you're all set. The No-Prize explanation for their appearance in this issue is that the new CG uniforms hadn't arrived yet, so Cobra Commander issued surplus HISS Driver outfits in the meantime.
