Being the assassin or the protector of Sarah Conner, Terminator always showed a disturbing figure. Even in the middle of a shooting, the petrous Schwarzenegger didn’t move a muscle of his face even if he lost half of it. This can be seen in the threatening bust of the Terminator with lights where the cold metallic android appears behind the torn apart skin.
And don’t believe that is was any kind of metal. To be exact, it was a titanium and tungsten alignment wrapped in a human like tissue and with Arnold’s features. A perfect machine to travel in time, handle shotguns of any size, drive motorcycles and scan everything with those robotic and penetrating red lights.
