Concept art exists for an unused "Parasite Woman" enemy, in both an "A-Type" and "B-Type". The "A-type" shows her bound in a straitjacket, and one of her arms has grown to gargantuan lengths. It would appear that her design was reused for the J'avo in Resident Evil 6.
The "B-Type" variant has no arms free at all, and her head has transformed into a sharp-toothed monster.
The third piece of concept art is an unbound woman in a tattered dress, armed with a shotgun.
The final design, merges the earlier designs - an unbounded woman with two inhuman arms growing next to normal ones, while a monster's face projects from the side of her head.
The creature's straight-jacket concept shares an uncanny resemblance to the Nosferatu From Resident Evil Code: Veronica X and Lisa Trevor from the Resident Evil remake.
