Phantom Mangle appears to have half of its left eye missing although it could be obscured by something else. It lacks eyes and instead has pin-pricked, white pupils.
Phantom Mangle has, essentially, the same model Mangle did in the second game, but with a burnt appearance, possibly foreshadowing the fire that broke out in the establishment. It is a hallucination of a burnt and damaged Mangle.
Phantom Mangle is one of the secondary antagonists and six phantom animatronics who first appeared in Five Nights at Freddy's 3.
