Right, as for their creation, the only thing that's known is that these nerds get hooked up to a machine via a helmet that constantly monitors their brains and thoughts. Then inside the machine, the girls are "printed" so to speak.
they are essentially artificial people. Not vat grown, but they have flesh, muscles, feeling in all parts of their flesh being (and dependant if you want them to have, even in their metal as well). However, their flesh is tougher, their muscles stronger ans senses enhanced. their blood runs black, one of the major denotations that they're not exactly human. They (again, depending on their creator's mind) may or may not have ports and places that their armor, weapons, gear in general would attach to them at. 

My apologies, it's been upwards of a year since i've ran an rp, but i have a good feeling about this.
