Popularized with the game Plasmophobia, “The Mimic” is an elusive and mysterious ghost that has the ability to mirror traits and behaviors from other ghost types. It can imitate any type of ghost and inherit all of its features and abilities. Yet, whenever it mimics a specific ghost, it cannot copy the evidence of that ghost type.
In the realm of the paranormal, mimicry is most often the result of a Poltergeist. – See Poltergeist
