''[[caption-width:180: Obey... Obey...]]''

This is the device that the villain (usually) will use to keep the hero, townspeople, or Mr/Mrs. Random Supporting Character in thrall. It has been used countless times in stories across many different types of media. [[OverusedSciFiPlotDevices Plot Device]], {{MacGuffin}}, and even a key part of a VerySpecialEpisode.

While these devices tend to fall into two general categories, either broadcasting "hypno-waves" at any luckless viewer for a one-time treatment, or are somehow attached to the victim's body (usually the head), they ultimately know no shape and can come in nearly any specific form:

That sword you just picked up? ''[[WarCraft Hope you like being a slave to the evil overlord]].''

That mask that looks so good on you? ''[[TheMask Hope you can control the demonic power inside]].''

That shampoo you're using? ''[[KimPossible Dr. D's BrainWashing Shampoo and Cranium Rinse]].''

See MindControl, MindControlEyes and MoreThanMindControl for the effects of these devices. May be the result of televising a person with the power of HypnoticEyes.
Subtropes include: {{Subliminal Seduction}} and {{Hypno Ray}}.
See also: PowerPerversionPotential for the inevitable result in some viewers.

!!Examples

[[folder:Anime & Manga]]
* ''ShugoChara'' mainly has X-Eggs and now they've took it a step further. Now they have Question Eggs which turn people into DARK Chara Naris.
* ''SailorMoon'' has had this in spades.
** Artist Girl -- Pencil
** Prince Endymion -- Queen Beryl
** Chibi Moon (Rini) -- Wiseman
* Shampoo of ''[=~Ranma ½~=]'' uses hypnotic pressure points, mind-control mushrooms, and memory-erasing shampoo at various points to further her sinister plots. The plots usually don't work, the items/techniques work flawlessly. Not only that, in the final story arc she is ''imprisoned'' in a ''mind-control egg'' and emerges the slave of the bad guys.
* The Consideration Console in ''MagicalGirlLyricalNanoha [=StrikerS=]''. Implanted in [[spoiler:Lutecia]] by [[MadScientist Jail Scaglietti]] so that someone like [[SmugSnake Quattro]] could [[VillainOverride override her thoughts]] should the need arise.
[[/folder]]

[[folder:Card Games]]
* ''[=~Magic: The Gathering~=]'''s [[http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=46724 Mindslaver]], in the sense that you have entire control over what your opponent would do for their turn. Indeed there's a popular deck that wins by being able to use mindslaver on every turn to prevent your opponent from being able to do anything.

[[folder:Comics]]
* Spellbinder from The ''{{Batman}}'' comics.
* The Mad Hatter also from the ''{{Batman}}'' comics.
* The Ringmaster, with his hypno-spiral top hat, has battled nearly every hero in the {{Marvel}} universe at one point or another. (And lost.)

* [[MarvelUniverse The Marvel Universe]] has the Serpent Crown, a mind control device used to channel the power of Set, an [[EldritchAbomination Elder God]]. Many [[SuperHero superheroes]] have fought villains attempting to conquer the world in the thrall of Set.
* An unusual version shows up at the start of the {{Deadpool}}/GreatLakesAvengers Summer Fun crossover. It just makes its targets ''drunk''.
[[/folder]]

[[folder:Films]]
* The gigantic hypnotic spinning wheel from ''The Incredibly Strange Creatures Who Stopped Living and Became Mixed-Up Zombies''.
* A similar wheel appears briefly in the spy-spoof ''OurManFlint''.
* While a flashing hand-held version was used by the villain in ''TheHypnoticEye''. (Actually, he was [[spoiler: the [[TheManBehindTheMan real villain's]] semi-willing stooge]].
* The golden mask in the hilarious B-movie ''PumaMan''.
* Ceti Eels are a living version of this from ''StarTrek II''.
* Let's also not forget the [[strike:flashy thing]] Neuraliser from ''[[MenInBlack Men In Bl]]''-- *flash* Forget what?
* The first ''NakedGun'' film had this as the main weapon of the villains.
* Stryker kept mutants in his thrall by administrating some sort of evil liquid to the next in the second ''X-Men'' movie.
* In the mostly forgettable (if you're lucky) ''[[TheWildWildWest Wild Wild West]]'' movie, Artemus Gordon uses one to gain information about the BigBad's plans.

[[/folder]]

[[folder:Gamebooks]]
* In Book 3 of the ''LoneWolf'' series, ''The Cavern of Kalte'', evil sorcerer Vonotar the Traitor uses gold bracelets to control the Ice Barbarians. Putting one on your wrist is a ''[[DontTouchItYouIdiot very bad idea]]''.
[[/folder]]

[[folder:Literature]]
* The [[BuffySpeak wiggly thing]] from the evil horses on ''{{The Fate of the Fallen}}''.
* In the later ''HonorHarrington'' novels, a rogue planet of eugenicists called Mesa develops a nano-virus that is capable of compelling behaviour out of its victims. It is used several times to stage assasinations and get rid of key enemies and is noteable in the series for being initially dismissed as impossible because they've had mind control tech for centuries but every military has its people protected against it.
* Trombophone Music in ''{{The City of Dreaming Books}}''. While we see a taste of it early in the novel, exactly how powerful it is doesn't become apparent until the very end.
* The 3D Hypno-Ring from ''CaptainUnderpants''.
[[/folder]]

[[folder:Live Action TV]]
* ''StarTrekVoyager''. Homaged in the ''Captain Proton'' holodeck program in "Thirty Days". The Twin Mistresses of Evil (played by the famous Delaney twins) have Buster Kincaid (played by Harry Kim) chained up so they can use the terrible Brain Probe, which they promise will turn him into their grovelling slave. Harry does not seem particularly adverse to the idea.
* Several different varieties turned up during the original run of ''DoctorWho''; sometimes it was even the Doctor himself using them.
* If Karl Rove gives you a cookie, ''[[http://www.thedailyshow.com/video/index.jhtml?videoId=209408&title=Chris-Wallace don't eat it.]]''
* One of these is used in ''RedDwarf''. It only controls the body, giving a rather interesting discussion between victim and targets.
* _Nobody_ is mentioning the ''{{Star Trek}}'' ep "Dagger of the Mind"?????
* Used comedically (of course) in ''AllThat'', with Hypnopants, the evil villain with hypnotic pants. [[spoiler:At least once he was beaten by Boring Man boring the pants off him.]]
[[/folder]]

[[folder:Tabletop Games]]
* The Helm of Opposite Alignment was a fun one of these in earlier editions of ''[[DungeonsAndDragons Dungeons & Dragons]]''. Spells like CharmPerson were a more temporary form.
[[/folder]]

[[folder:Video Games]]
* Majora's Mask, from the titular ''{{Legend of Zelda}}'' game.
* Heroic version: ''LittleKingStory'' for the Wii from the makers of ''HarvestMoon'' features a little boy finding a magical crown that commands the obedience of all around him.
* ''[[CommandAndConquer Command & Conquer]]'' features mind control with Yuri in ''Red alert 2'' and the "Yuri's Revenge" expansion pack. Units change side (and color) and start fighting against you.
** ''The Tiberium Wars'' games feature the Scrin Mastermind, an alien with the ability to take over units and buildings in a similar manner to Yuri.
* Terra, one of the characters of ''FinalFantasy VI'', wears a slave crown and thus is mind controlled.
* Arthas' sword Frostmourne in ''{{Warcraft}} III'' is a tool of mind control.
** In ''{{World of Warcraft}}'', players with engineering trade skill can learn how to craft a mind control device that allows them to temporarily control a player or a creature (it's highly unreliable and won't work on high level targets, though).
* The old video game ''{{Paradroid}}'' had you playing as one of these. You controlled the "Influence Device", used to hijack rogue droids on a ship suffering from a RobotRebellion.
* You, the BrainInAJar in ''CortexCommand'', use this to control units. Good thing too, since so far, the AI is pretty darned dumb.
[[/folder]]

[[folder:Web Comics]]
* ''MutantNinjaTurtlesGaiden'' put this to immediate use at the start of the series, giving us a chance to watch the turtles try to kill each other, bringing their emotional hot spots to the forefront, and allowing the viewers to realize that with this much blood and agony, the webcomic certainly isn't going to be as kid-friendly as [[WesternAnimation/TeenageMutantNinjaTurtles1987 the cartoon]].
* The "slaver wasps" from ''GirlGenius''.
[[/folder]]

[[folder:Western Animation]]
* A staple prop in many sillier cartoons. Expect the word "hypno" to appear somewhere in the device's name.
* For most of ''{{Disney/Aladdin}}'', this is the only function of Jafar's snake staff.
* ''KimPossible'' offers quite a few examples:
** Compliance Chips ("Total mind control!");
** [[EmotionBomb Mood-controlling]] "Moodulator";
** "Hypno-Ray" inside a disco ball;
** Love-creating Cupid Ray;
** "Dr. D's Brainwashing Shampoo and Cranium Rinse."
* ''Spellbinder'''s eye thing from ''BatmanBeyond''. The spiral theme to his costume is probably supposed to heighten the effect.
* Mad Mod's hypno-screens from ''TeenTitans''.
* Deadeye from ''ChopSockeyChooks''. By the way, if anyone knows the correct spelling of Sockey, let me know.
* The Hypno-Ray from several episodes of ''JimmyNeutron''.
* ''EdEddNEddy'' used one of those spinning things to brainwash everyone in the cul-de-sac in the episode "Look Into My Eds". Then the Kanker Sisters got their hands on it...
* The Mad Hatter from ''{{Batman the Animated Series}}'' controls minds without spirals, using cards marked 10/6 which he sticks on people's heads.
** And that's just his stock device; he has been known to use other things when appropriate.
* Freakshow from ''DannyPhantom'' had a mystical staff that could be used to mind-control ghosts... or half-ghosts in the case of Danny.
* In ''{{WordGirl}}'', this is recurring villain Mr. Big's whole gimmick.
* Sublimino's pocketwatch in ''{{Ben10}}''.
* ''Chowder'' is partly controlled by a lollipop with a swirly pattern.
** Once Chowder gets tired of it, he gets controlled by a cinammon swirl, then pizza.
* In ''CodeLyoko'', XANA manages to sneak an enhanced piece of jewelry to Aelita, who's usually immune to the mind control through his specters, by disguising it as a Valentine's gift from Jérémie.
* Many devices in the ''Transformers'' multiverse are able to temporarily "overwrite" the personality and faction programming of one side with that of the other.
** The Headmasters are an entire race of these. Sort of.
* ''{{Futurama}}'': [[CreepyMonotone All glory to the Hypotoad.]]
* "Must! Do! Wonderful! Things! For my! Best! Friend! [[RenAndStimpy Stimpy!]]"
