Endo-01 is a bipedal humanoid robot composed of thinner, tube-like structures for the limbs and stomach. Its flat rectangular head consists of a movable mouth with teeth and a pair of blue eyeballs.His design from the first game is quite simple, while he sports rectangular cube-shaped fingers and two-toed feet. In Five Nights at Freddy's VR: Help Wanted, the robot is seen to have several additional tubes around its head, a series of cables connecting some parts around both sides, hands and feet.
