The Glamrock Endoskeletons are minor antagonists of Five Nights at Freddy's: Security Breach.
The Glamrock Endos are first encountered by Gregory on his way to Parts and Service, The endos will only move if Gregory looks away from them and will not attack Gregory if he maintains direct eye contact or if he is in Glamrock Freddy. As Gregory goes through the Backstage area more Endos will begin to activate as he passes them and when he takes the security badge from the office a large group will become active and attempt to kill Gregory while he isn't looking at them and Gregory must evade them while making his way to Parts and Service. The Endos are later encountered again in both Bonnie's Bowling Alley and the Faztheater in large groups where they must be avoided while leaving both locations.

- The Glamrock Endos may also be a reference to Endo B "Angel" from the popular FNAF fan game "The Joy of Creation" who was also an animatronic endoskeleton who could only move while not being looked at
