On Penny, my bet is on her being a cyborg prototype, mainly because I think there is some aura capability, requiring a soul, in her. So she'd be more a 'Six Million $ Babe' as an allusion, in addition of course to that to one of Monty Oum's previous works.

But regardless of whether robot or cyborg, the question is who build her and to what end?
