An Abnormality whose appearance resembles a human, but cannot and should not be human. It periodically devours employees and wears their shell. The skeleton and organs are misplaced during the process, so it takes a bizarre form. 
This Abnormality may be evolving. It demonstrates behavior similar to the character of the person who used to be its shell. It even makes attempts to equate itself with human beings.
"And the many shells cried out one word, "Manager"."
