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 metallic endoskeleton. It lacks eyes, and has white colored block-like 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 their 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. It is also shown on the backstage, where it will occasionally 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. It also made 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. It plays a huge role in the Workshop as it is the base model of all the animatronics. The player can apply different Plush Suits, CPUs, Remnants and MODs on it to change his appearance and behavior. It can be sent to salvage and collect Parts, and deploy it to attack other players.

Flamethrower Bare Endo THD Render.png

Flamethrower Bare Endo is the new "Summer"-themed animatronic added in the July 23, 2020 update from Five Nights at Freddy's AR: Special Delivery.


Flamethrower Bare Endo is an orange endoskeleton with a large red welding mask and two large gas canisters on its back. The canisters are hooked up to a flamethrower attached to its arm.


Dark Water Bare Endo is Bare Endo's second skin and the first skin of the Wicked Tides event. They arrived on May 20th, 2021.


Dark Water Endo barely resembles their normal counterpart anymore, as they are now covered entirely in a watery casing. They have multiple small tendrils coming out of their arms and torso and their hands are colored black with their fingertips glowing sky blue. Their torso is filled with a multi-colored pattern that looks similar to coral. Their head looks extremely similar to that of an angler fish, with their mouth having a more fish-like look with thin, sharp teeth and multiple sharp, curled tendrils sticking out of the lower side. They have two large fins on each side of their head and the iconic angler fish antenna on top of their head. Finally, both of their eyes are large and glow a bright white.


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 it 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. However, 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 unobtained 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.
    • This was fixed in a later update.
      • Despite being fixed for Flamethrower Bare Endo, Dark Water Bare Endo experienced the same thing when it released.
  • Dark Water Bare Endo was revealed via multiple in-game teasers that showed various puzzle pieces.
    • Many believed the pieces to be either Ballora or Foxy, until the face was revealed.
  • Dark Water Bare Endo, by technicality, is the first fish-based animatronic.
