Sigourney Weaver as Gwen DeMarco as Lieutenant Tawny Madison of the NSEA Protector.  That being said, her job on the ship was to repeat whatever the computer said, and do bad karate poses.  Geometric Designs provided Tawny's face from the "Ripley" figure, but everything else was hand-sculpted from Sculpey.  No, her hands aren't really that large.  Blame the angle of the picture.

Is she not nifty?  Even if you don't worship the figure, at least worship her ... um, talents.
