Since she is going to be basically a assistant to Dave I think I need to post this here.

Function: Sarah is an android specifically for Dave's care. Her "skin" is made from the same metal that his suit and armor are made of and houses millions of small scales that house a type of camouflage in the form of an actual human being. While she could become a powerful combatant, her programming restricts her to basic assistance and can only activate these battle subsystems during extreme incidents that endanger Dave's life. Sarah's AI is extremely advanced, able to make situation adjustments to her "attitude" to fit almost any given emotional situation and unless you know the truth it is almost impossible to tell her from a human.
