Six-Gun was a created-to-die character who appeared in IDW G.I. Joe issues 8 and 9, alongside Hat Trick. Both were ripped to pieces by a mechanical monstrosity deep in a dark dungeon. They have nice designs though, so I wanted to replicate them as best as I could. Six-Gun wears dirt bike protective gear over his fatigues, so I used a torso I had on hand from Angel Forge that approximates that. He also wears a motorcycle helmet, for which I modified a Backstop helmet. He doesn't actually have night vision goggles in the comic, but I had a pair of goggles from a Remco American Defense figure of all places that fits absolutely perfectly on this helmet, so I couldn't not use it. The head is from a Lanard construction worker figure, and it's actually a really nice sculpt.
