A bare endoskeleton can be seen in the Prize Corner and Left Vent, though it never attacks the player. There are some interesting fan theories about which animatronic this endoskeleton belongs to.

Endo-02 is an endoskeleton designed for the withered animatronics and some toy animatronics in Freddy Fazbear's Pizza during the 1980s era. The Five Nights at Freddy's 2 game marked the extra suitless endoskeleton's first debut.

Physical Appearance

This endoskeleton seems much detailed in appearance than its another variant Endo-01, being shiny and silver in color. It sports with three rib-like cages, cylinder limbs with spiral springs, a wide mouth filled with squarish teeth, and flat, three-toed feet.

Its overall appearance bears a lot of striking similarities to Withered Foxy's endoskeleton due to its nearly identical body structures, with ears in exact same shape but facing in a different way. Endo-02 also has hazel-blue eyes similar to those of Withered Freddy's.

From the second game, a bundle of long wires can be seen sticking out behind its back, apparently identifiable when at the Prize Corner. These are absent in its VR game appearance, however.


Akin to other endoskeletons, Endo-02 has functional eyelids, joints, jaw, knuckles, and (sometimes) ears. They are created as inner skeletons for the older withered animatronic cast at first, and reused for the toy animatronics albeit Balloon Boy, JJ, and the Puppet.


Five Nights at Freddy's 2

Endo-02 appears to wander the restaurant at rare intervals, but can be encountered as early as Night 1 and onward. It has 1/10 chance to appear in the Prize Corner (CAM 11) and 1/1000 chance to be seen in the Left Air Vent (CAM 05). Endo-02 can be seen at any time, but very rarely, and the chance goes up when the Music Box runs out, before the Puppet leaves the Prize Corner. It will not attack or jumpscare the player.

Endo-02 can sometimes block Withered Bonnie, Toy Chica, and Balloon Boy from entering the Left Air Vent, giving it a negligible impact on gameplay.

Five Nights at Freddy's VR: Help Wanted

Endo-02 reappeared in Five Nights at Freddy's VR: Help Wanted, but only in the FNAF 2 game mode. Unlike from the second game, Endo-02 has a very divergent role, as the endoskeleton has a rare chance to appear standing at the right side inside the Office for the whole night. Endo-02 can also occasionally appear under the floor from the Vent Repair level mode.

From the Curse of Dreadbear DLC, Endo-02's head appeared in the Spooky Mansion mode's "Build-A-Mangle" segment where it is randomly used for creating a mangled animatronic entertainer.

Five Nights at Freddy's VR: Help Wanted





Endo-02 as seen in The Silver Eyes graphic novel with Henry Emily.

  • The style of Endo-02's head is very similar to the Kismet robot, a robot created in the late 1990s at Massachusetts Institute of Technology by Dr. Cynthia Breazeal.
  • There is an endoskeleton who briefly appeared over few times in The Silver Eyes novel from the franchise's novel trilogy universe, designed by Henry Emily. In the graphic novel adaptation, the endoskeleton was depicted as Endo-02 itself.
    • The Suicide Bot, as depicted from the graphic novel, also bears a nearly identical resemblance to Endo-02. The only difference is that the Suicide Bot is featured with a sharp carving knife for its right hand.

Five Nights at Freddy's 2

  • Endo-02 is featured in update patch 1.03.
  • Endo-02 did not appear in the original mobile devices upon first release. It was later re-added in the remastered port.

Five Nights at Freddy's VR: Help Wanted

  • It is entirely possible that Endo-02 is a backup endoskeleton for Mangle. This is supported in the code as Endo-02 has two model files named "MOD_Endo2" and "MOD_Endo2_PoseForMangle."
  • Even though Endo-01 and Nightmare Endo appeared in the Gallery mode, Endo-02 was never included.
