Entity 9, frequently referred to as Facelings, The Vacant Faced, or scientifically Homo corruptum are a species of humanoid beings that inhabit a vast majority of The Backrooms' levels. As aforementioned, their appearance mimics those of humanoids, however, they feature several unsettling and unorthodox abnormalities on their bodies which make them different from normal humans. Most wanderers insist that they resemble normal humans enough from afar; if certain parts of their body are concealed or they are oriented in a certain way. Closing the distance will reveal an uncanny and sometimes horrifying presentation of the Facelings, with their most notable features being the complete lack of any facial features.

Wanderers note that most Facelings have a mannequin and artificial intelligence-like appearance, or that they look computer generated, giving them an eerie and unrealistic appearance. Roughly 40% of Facelings feature this "fake"-like appearance. This strange appearance is not as noticeable until one is around 12ft (~3.7m) away from the Faceling in question. Explorers have described the absence of some or all of a Faceling's facial features as a decent to downright terrible photoshop job using the delete, smear, and/or blur tool. The resulting look favors a piece of flesh stretched over the skull or gives the being a 'bubble-head' appearance.
