Penis Pincher is the robot companion created with the Robot Workbench from the Automatron DLC that accompanies Robbaz throughout the wasteland. He is also the last surviving member of Robbaz's battalion of robots.
Penis Pincher is composed of a Mr. Handy torso with an armoured eye. His legs are those of a Protectron along with his arms. His hands are vice grips hence the name "Penis Pincher". He speaks in robotic bleeps.
