[[caption-width-right:300:An ArmCannon: the perfect weapon when you can't move your fingers independently]]

A sister trope to DemonicDummy, the Murderous Mannequin is a clothing mannequin brought to life and sent to kill. Like MechaMooks, a hero can be shown cutting down swathes of these without moral qualm as they are '[[WhatMeasureIsANonHuman not truly alive]].'

Also make for excellent ParanoiaFuel -- they're everywhere, and they're ''staring at you''.

Like the CreepyDoll, DemonicDummy, and PerversePuppet, part of the eeriness is down to the UncannyValley.

!!Examples:

[[folder:Advertising]]
* There was an ad for Levis where guy buys a pair of Levi's jeans off a mannequin in a store. Mannequin proceeds to follow him home, lurks creepily outside his house... and the last shot is the mannequin's shadow sloooooowly moving over the guy's sleeping form.

[[folder:Anime and Manga]]
* ''FlameOfRecca'' , though it was a surprise. The heroes came upon a beautiful woman and her small doll, who were able to use strings to restrain and kill their enemies. One of them realized that the woman never bled, and so figured out instead of the woman making the doll talk, the doll was actually a little girl, using one of the magical artifacts to give the mannequin life. Cue tragic backstory.
* One of [[JunjiIto Junji Ito's]] short stories was about an artist who made headless mannequins (though his reason was for people to appreciate the body-language, not the face). Then his creations came to life, began killing people, and placing the victims' heads on their necks. Yeah.
* In ''Manga/FairyTail'' during the Fighting Festival arc, Bickslow move his [[OurSoulsAreDifferent "babies"]] inside some mannequins. While they don't become "alive", they can still float around, move and shoot laser beams at Gray.
[[/folder]]

[[folder:Comic Books]]
* There's a pulp comic called "Mannequin of Murder" in which a guy invents a serum to freeze people into mannequins. This is intended as a form of AndIMustScream torture, but they eventually come back to zombie-esque life and kill their creator. Then they go back to posing, get shipped all over America, and start going on killing sprees after dark.
* BrotherPowerTheGeek in TheDCU is a heroic version of this, although he turned pretty creepy when NeilGaiman decided to play with the concept. He appeared again in ''ComicBook/TheBraveAndTheBold'' (revival) #29 where he was more of a kind Frankenstein's monster who disappeared under the sewers after saving a child from a fire.
* Nathan Dolly, from ''ComicBook/SpiderWoman'', managed to transfer his essence into two mannequins and used them to commit several crimes.
[[/folder]]

[[folder:Fan Fiction]]
* Downplayed in ''Fanfic/CalvinAndHobbesTheSeries'' - there are creepy mannequins, but they don't move. [[spoiler:Except for the MonsterClown one...]]
[[/folder]]

[[folder:Film]]
* A horror short from 1980 called ''Living Dolls''.
* Frank hallucinates being ripped apart by his own mannequins (on which he placed the scalps of his victims) in both versions of ''Film/{{Maniac}}''.
[[/folder]]

[[folder:Literature]]
* The evil of Crystal Lake brings a House of Horror ride's mannequins to life in ''Franchise/FridayThe13th: The Carnival''.
[[/folder]]

[[folder:Live-Action TV]]
* The Auton animated shop dummies from ''Series/DoctorWho'' are the preferred footsoldiers of the plastic-controlling Nestenes whenever they visit Earth. They only appeared twice in the classic series run, but the sight of them coming alive, climbing out of windows and killing people in the streets was one of the show's most iconic scares. There's a reason they're the first MonsterOfTheWeek in the revival.
* A witch animates mannequins as minions in the ''KolchakTheNightStalker'' episode "The Trevi Collection".
* ''TheTwilightZone'' episode "The After Hours". [[spoiler:This angle is played up throughout the episode, although it's somewhat averted at the end when it's revealed that the main character is a mannequin who got the chance to experience human life, and now it's another mannequin's turn. The 1980s remake has pretty much the same plot, but the mannequins are much creepier (and the main character's transformation back into a mannequin is [[BodyHorror much more]] [[AndIMustScream painful looking]]).]]
* A {{Yandere}} one appeared in an episode of ''Series/TalesFromTheDarkside''.
* In the ''Series/{{Supernatural}}'' episode "Mannequin 3: The Reckoning", the MonsterOfTheWeek possesses mannequins to kill its victims. It sure was lucky that all of its targets happened to work with mannequins [[spoiler:or use sex dolls]], though.
* A subversion in the recurring sketch on ''Series/{{MADtv}}'' featuring a psychotic murderer who everyone (except the OnlySaneMan) thought was just a mannequin because he would stand really still whenever anyone was looking directly at him. Anyone else who eventually noticed the mannequin kept changing positions would come to the conclusion the OnlySaneMan must have been the one to move it and kill all those people for whatever reason.
* This might be the best way to explain the puppet versions of previous SuperSentai teams unleashed by Basco in ''Series/KaizokuSentaiGokaiger.'' They basically reanimate previous teams powers in the form of keys, who then become life size. There's no person in the suit, and yet they're trying to attack.
* Maxwell Smart takes on an animated wax dummy of JackTheRipper in the ''Series/GetSmart'' episode "House of Max".
* Jeff from ''TodaysSpecial'', only without the "murderous" part.
[[/folder]]

[[folder:Roleplay]]
* ''Roleplay/DestroyTheGodmodder'' has the creepy dummy. It was summoned rather innocently in the first game wearing a shirt that said: "godmodder's friend" on it. then it started to go downhill.
** It was amusing at first, but then it started to tear people's faces and arms off.
*** But then everyone forgot about it and it just sort of disappeared.
** Until the second thread, when it came back even worse than the first time around.
[[/folder]]

[[folder:Tabletop Games]]
* Colette Du Bois of ''{{Malifaux}}'' provides her showgirls with [[TheBlank faceless]], magical, clockwork mannequins that act as dressmaking mannequins, assistants, and bodyguards.
[[/folder]]

[[folder:Videogames]]
* The Mannequins in ''VideoGame/SilentHill2''. They look a bit a [[http://images2.wikia.nocookie.net/silent/images/thumb/1/1c/MannequinSH2.jpg/300px-MannequinSH2.jpg bit different]] than most mannequins, though.
** Subverted in ''VideoGame/SilentHill3'' -- those who played [=SH2=] would expect ''something'' from a mannequin conspicuously framed and lit in the center of a room that must be crossed in order to get an item...
* Subverted in ''VideoGame/{{Condemned}}''. Though several mannequins appear to follow you around in the department store level, even completely encircling you when you fall into a dark pit, they never actually attack you.
** However, there ''are'' crazy homeless mannequin impersonators on that level, who ''will'' attack you.
* In the Fort Frolic level of ''VideoGame/{{BioShock|1}}'', you see what appear to be mannequins all around the place, though it becomes pretty obvious that they're actually Splicers who have been killed, coated in plaster and posed around the place by Sander Cohen. Even worse, some of them aren't dead.
* Subverted in the ''VideoGame/{{Half-Life 2}}'' mod ''NightmareHouse 2'', which has you spending one level with a lot of mannequins - which multiply and come closer when you do not look at them, but do not attack. [[spoiler:You then encounter a SWAT officer knocking on a window from another room and using gestures to show you where to go. When you get to the place where he was, there is just a mannequin.]]
* In ''VideoGame/FinalFantasyXI'', after mannequins were added as furniture for player houses, they eventually started to be added as rare special enemies too.
* Subverted in ''VideoGame/TheElderScrollsVSkyrim''. Due to [[GoodBadBug bugs]], mannequins in the player's house would sometimes get off their pedestals and stand in other places. Since it's just a placement error, this would mean the suit of 7-foot [[SpikesOfVillainy Daedric Armor]] standing menacingly just around the corner is completely harmless. Other times, they would employ idling animations to move slightly, wave their arms, and sometimes ''turn their heads to look at you with their eyeless faces''.
* PlayedStraight and {{Subverted}} in the ''[[VideoGame/AmnesiaTheDarkDescent Amnesia Custom Story: The Things in the Night]]''. Some mannequins (read suits of armor and statues) follow you, some hurt you if you get near them, one talks to and hurts you if you ''touch'' it, some seem to move to shield you from view, and at one point [[spoiler:some outright talk to you and protect you from a Brute.]] It [[ZigZaggingTrope Zig Zags]] all over the place.
* Jack the Ripper appears in the Sega platform game ''VideoGame/{{Master of Darkness}}'', where he is revealed to be an animated wax doll upon defeat.
* ''VideoGame/{{Maplestory}}'' has these as enemies in the Kerning Square area.

[[folder:Webcomics]]
* ''SilentHillPromise'' has at least a pair of them.
[[/folder]]

[[folder:Web Originals]]
* The Wiki/SCPFoundation has [[http://www.scp-wiki.net/scp-847 SCP-847]]: a usually normal seeming (if damaged) female mannequin, it comes to life if [[MonsterMisogyny a woman]] approaches within 100 meters of it, with a single minded determination to murder the woman and [DATA EXPUNGED]. It's only known weakness is [[TaserTagWeakness electricity]], which will temporarily render it dormant.
* Played with [[http://www.youtube.com/watch?v=La6T8Bq6CsU here.]]in a short film called ''Still Life''.
* ''WebOriginal/{{Worm}}'' has Mannequin, a serial killing Supervillain.

* The ''WesternAnimation/MonaTheVampire'' episode "Night of the Living Mannequin".
* A villain in ''WesternAnimation/InchHighPrivateEye'', known for being a GadgeteerGenius (to the point that he even evaded arrest by fooling the police with a life-like replica of himself), built robots disguised as ordinary mannequins, sold them to department stores, then used them to rob the stores and return to him.
* In the ''WesternAnimation/SuperFriends'' episode "Mxyzptlk's Flick", Mxyzptlk brings some mannequins to life with his RealityWarper powers. They actually manage to beat the crap out of Superman even before one brings out some kryptonite.
* One of ''WesternAnimation/SheZow'''s enemies is Manny Ken: a gigantic animated shop mannequin.
