There are six ways a surgeon can cut the skull, and I figured Dr. Frankenstein, who was not a practicing surgeon, would take the easiest. That is, he would cut the top of the skull off straight across like a pot lid, hinge it, pop the brain in and clamp it tight. That's the reason I decided to make the monster's head square and flat like a box and dig that big scar across his forehead and have two metal clamps hold it together. The two metal studs tat stick out the sides of the neck are inlets for electricity - plugs. Don't forget, the monster is an electrical gadget and lightning is his life force.
