Endo-01

The model of endoskeletons used for the classic animatronics - given the alias Endo-01 by FNaF World - is a reoccuring character in the Five Nights at Freddy's series.

Appearance
This endoskeleton is rather bare-bones, with simple spherical joints at the shoulders, limbs and pelvis. The chest of the endoskeleton has two extra pipes leading up to the skeleton's clavicle, and then another two leading from there to the endoskeleton's head. The head of the endoskeleton is rather flat and thin, with the mouth jutting out like a beak and the eyes popping out.
