HandUnit, Five Nights at Freddy's AR: Special Delivery

Endo-01 is an endoskeleton who is designed as an inner robot "skeleton" to use for the inside of the four original animatronics' suits in Freddy Fazbear's Pizza. Although there is an extra suitless endoskeleton that exists in Five Nights at Freddy's as its first appearance.

Endo-01 returns again in Five Nights at Freddy's VR: Help Wanted as an easter egg. It also reappears in Five Nights at Freddy's AR: Special Delivery as an antagonist.

Physical Appearance

Endo-01 is a bipedal humanoid robot composed of thinner pipe-like structures for limbs and stomach. Its flat rectangular head consists of a movable mouth with teeth, and a pair of blue eyeballs.

Its design from the first game is slightly simple, while sporting rectangular cube-shaped fingers and two-toed feet. In the VR game, Endo-01 is tweaked with additional tubes around the head, a series of wiring connecting some parts around both sides, hands and feet (comes with three toes each) made similar to the withered animatronic's endoskeleton, and possesses tiny red lens as seen without eyeballs.

Functionality

Created for the classic animatronics, the endoskeleton's basic capability is technically designed to move joints, eyelids, jaws, and ears (except Chica), while allowing the animatronics to roam around freely at nighttime.
