Doctors are generally tall, lean zombies, heavily armored on their heads, necks, shoulders, and backs. While one or two arms may be mechanical with cutting tools, blades and a laser, its other arms are usually normal human limbs, as Doctors require a more refined touch for the work they do. They usually have 4-6 arms, sometimes of various sizes, races and genders, for their repair work. Doctors use both surgical tools and hardware (drills, saws, bolt cutters, screwdrivers, hammers, etc.); sewing, wiring, soldering and bolting body parts and machinery to the dead flesh and bone of the zombie hordes. Many have cybernetic eyes, or wear multi-optic goggles or similar eye-wear and optic systems for magnification and close work; sometimes attached right to their skulls! To someone seeing a Doctor for the first time, it may look like a Frankenstein monster or bizarre, multi-limbed cyborg or insectoid robot, or even an alien from another world; always a horrific abomination, no matter the form it takes.
