The way I imagine a potential Armor figure is a standard figure clipped by the waist inside a translucent, hollow shell. Maybe swivel articulation at the neck and shoulders, maybe even the hips, though any leg articulation would result in the necessity of ankle articulation to stabilize the figure. The neck shoulder swivels would also remain hollow to accommodate her head and arms to float inside (again, her attachment is mostly at the waist with a clip to the back of the armor). It doesn’t need to be huge armor, it could be smaller than the Cobra SNAKE armor.
