I thought I'd seen most of the old GI Joe cartoon. Then I bought the excellent GI Joe Field Manual which collects characters and vehicle production art and discovered there was a treasure trove of episodes I hadn't seen and characters designs to inspire customs. Seeing the art for the original (and very different) ancestral mask for Destro, as well as the McCullen druids, I immediately looked up "Skeletons in the Closet" and was thrilled by the episode. I knew I wanted to try to incorporate the idea of COBRA meddling with a tentacled, mythos-esque monster in my 'Joe verse. Eventually, I've got a diorama set up I want to complete to house these COBRA Mystics, with a few more surprises. I also looked to The Spectre's amazing Cthulhu figures for inspiration on how to approach these druids. The Wolf replaces the somewhat goofy looking Wildcat mask from the cartoon.
