DD-13 Medical Assistant Droid has had every external component painted black as night, with attempts to minimize the brightness of external lights and features. This allows this DD-13 Medical Assistant Droid to more easily blend into the shadows and darkness unseen.

DD-13 Medical Assistant Droid has received advanced automated repair programming based on the original DD-13 Medical Assistant Droid schematics, giving it an ability to perform or assist in the performance of self-diagnosis and self-repair of its mechanical systems. This system engages automatically upon damage, and can render the droid temporarily unavaialble while it assesses any necessary repairs before further action can be taken.

DD-13 Medical Assistant Droid is subjected to frequent memory wipes, and has little to nothing in the way of personality. It acts according to its basic programming in an efficient and impersonal manner.
