He is a car crusher used in the same junkyard as his assistants, the Crane and Giant Magnet. As his name suggests, he is a large crushing machine designed for crushing cars. Since the Crusher needs the Giant Magnet to be able to accomplish this, it is likely that he and the Giant Magnet are both part of the same body. Like the Crane and Giant Magnet, the Crusher's only speaking role is when he sings "Worthless", but like Street Lamp and Traffic Signal, whereas most appliances and the Junkyard Cars can move, he cannot. His only moving components are; the conveyor belt that brings victim cars to him, and an upper-mandible piston which crushes them into cubes. It is unknown if the Crusher is alive or not; however, he does have two eye-like shapes above his mouth.
