While this brain parasite looks somewhat like the ones that took possession of the Invisible Girl in FF #227, they are not the same. The former ones caused Susan’s appearance to change dramatically. That is not the case here. Also, the shape of the parasites is similiar, but still a little different. It is possible that the inspiration for the Mannequin parasite came from the ones in FF #227. However, it is also possible that the inspiration for this creature came from the Star Trek film where Khan used a worm to control the mind of his victims. Then again, a third possibility exists. Maybe the inspiration for this parasite came from the one in the Stargate:SG-1 sci-fi series? Regardless, the Mannequin parasite must be an extremely powerful creature, as it disposed of Susan Storm’s force field in the blink of an eye.
