Endo-01, also known as Bare Endo in Special Delivery, is the animatronic endoskeleton of the Classic Animatronics. It debuted in Five Nights at Freddy's and returns in Five Nights at Freddy's AR: Special Delivery as an active antagonist. It also appears in Five Nights at Freddy's VR: Help Wanted as a background character.


FNaF VR: Help Wanted

Bare Endo is a dark silver metallic endoskeleton. It lacks eyes, and has white colored teeth and short sized limbs interconnected from their torso. However, apart from the first game, he seems more detailed, with more wiring and structure on it.

FNaF AR: Special Delivery

Bare Endo's appearance appears to be a light gray in color, with shining blue eyes. He is closely similar to the endoskeletons who appear in the suits of the animatronics of the first game. He has multiple connected wires, with metallic poles, all over his body.


Endo-01 was the endoskeleton model built for the new Freddy Fazbear's Pizza in FNaF 1 after the older pizzeria with the same name from FNaF 2 is closed.

Endo-01 is also shown on the backstage, where it will occassionally stare at the camera along with the empty mascot heads.

Endo-01's name was not actually revealed until FNaF World. Up until that point, it was simply referred to as "Endoskeleton".

Finally, in Ultimate Custom Night, it is seen that Endo-01 is the same endoskeleton model used for the Mediocre Melodies; a group of animatronics that appeared in Freddy Fazbear's Pizzaria Simulator as purchasable performers.


FNaF VR: Help Wanted

Endo-01 appeared in Ennard's Vent Repair level and Pizza Party in Night Terrors as a simple background prop.

Endo-01 also make its appearance in the FNaF 2 levels and Lolbit's level, altough rarely, but are only seen as cameos.

FNaF AR: Special Delivery

Bare Endo's jumpscare.

Bare Endo commonly appears as an antagonist, and can attack the player. He plays a huge role in the Workshop as he is the base model of all the animatronics. The player can apply different Plushsuits, CPUs, Remnants and MODs on him to change his appearance and behavior. He can be sent to salvage and collect Parts, and deploy him to attack other players.

FNaF VR: Help Wanted

  • Upon closer inspection of the old Endo model In the FNaF 1 mode, It is extremely low-poly.
    • The model used was a fanmade model that was later replaced.
  • Similarly to Nightmare Endo, Endo-01 has a place in the Gallery in favor of other characters.
  • Endo oddly has no eyes compared to FNaF 1. This makes him a completely blank slate (blue eyes for a Freddy Endo etc.)
    • As well as this, its head is covered in wires that weren't originally there in previous appearances.
  • Sometimes, in Funtime Foxy and Lolbit's levels, an endoskeleton will appear in the room.
  • There used to be a fan-model of Endo-01 in the backstage of the FNaF 1 Challenge. It was later patched out and replaced by it's actual model.

FNaF AR: Special Delivery

  • In FNaF AR, Bare Endo is an active antagonist, in contrast to the other games, where it was usually a background detail.
  • Endoskeletons are used to unlock other characters in the Workshop via giving them plushsuits.
  • Within the files, Bare Endo has an unused icon that's blacked out with a question mark over it similar to what appears for unpurchased plushsuits.
    • This image is never used in-game because the player is required to have a Bare Endo to access the workshop. It is unknown why it is there.
      • Bare Endo also has a darkened CPU icon, which also goes completely unused.
  • Bare Endo is the first to get a skin for the Sizzling Summer Event.
    • Said skin is Flamethrower Bare Endo.
  • Flamethrower Bare Endo, unlike all other skins, is listed separately from Bare Endo in the workshop.
    • This needed to happen due to an issue with stacking Endo's plushsuits, most likely caused by Bare Endo being the template for characters.
