Phantom Animatronics function as hallucinations to scare the player and serve as a mechanism to show your player hallucinating. The phantoms don't kill the player, rather they break ventilation or other systems. Also, they give errors to video, audio, ventilation, or an unfortunate combination of all three. They also serve to weigh out character amount.
All the phantom animatronics appear to be burned in some way. Some speculate that this is Scott trying to foreshadow the end of game newspaper clipping that shows the attraction burning down.
- It is theorised that the phantoms may not be hallucinations, but rather ghosts, either the ghosts of the murdered children trying to scare the protagonist away, or extensions of Springtrap, messing with the systems to allow him to kill the protagonist.
