While generally quite easy to mistake for an organic human there are a few ever present ticks that set Dorothy apart.  Her posture is to perfect, the precision of her movements to high, and her responces to subtle twists of language just a little off.  No one of these quirks would prove to someone who had never meet one that she was indeed a human form android, but once you see it you can never go back.

For the few unfortunate enough to encounter her more mechanical capabilities in a hostile environment it quickly becomes apparent that she is several steps ahead of anything a living breathing creature could manage and while not able to move faster than anyone else she knows where to be and when to be there far better than most and every now and then some form of high energy protection system engages and renders all but the most significant threat a moot point.
