[[caption-width-right:350:The [[MindControlEyes iris deformation]] ray is working!]]

->''"She looks hypnotized! He must have used that joy buzzer on her!"''
-->-- '''Paul''', ''WesternAnimation/{{Dinosaucers}}''

A standard gadget in the MadScientist grab bag. The HypnoRay allows the user to instantly hypnotize an unsuspecting target and make that person [[MindControl do their evil bidding]].

Often a RayGun, but the magical version usually takes the form of EyeBeams.

The sequence follows a standard progression:
* The MadScientist flashes the HypnoRay, instantly stunning the victim.
* The victim displays MindControlEyes and usually starts repeating anything the attacker says, often to his annoyance.
* The victim hears a suggestion that he must follow (often not what the attacker intended).
* The HypnoRay shuts off and the victim [[LaserGuidedAmnesia wonders what just happened]].
* The MadScientist realises a mistake in what he has said and has to flash them again.

The victim later hears the trigger and takes the action, no matter how inappropriate it may be at the time.

This can often be combined with a [[DoNotAdjustYourSet mass media event]] to TakeOverTheWorld.

These days, this type of device is usually limited to comedic settings.

A SubTrope of MindControlDevice.

See Also: HypnoFool, CharmPerson, JediMindTrick, WeakWilled, HypnoTrinket.

Not to be confused with HypnoticEyes.

[[folder: Comic Books ]]
* The first "super-villains" to appear in the ComicBook/MickeyMouseComicUniverse were a trinity of MadScientist apes named Professors Ecks, Doublex ([[SpellMyNameWithAnS or Duplex]]), and Triplex who wanted to use one of these to TakeOverTheWorld. They appeared in the "Blaggard Castle" storyline of daily strips, published in 1933.
** A more modern story had [[ArchEnemy the Phantom Blot]] pretend to be one of the Professors come back to try and rebuild & reuse the hypno-ray, after the castle had been rebuilt as an honor for Mickey.
* In the story "The Town That Went Crazy", in issue #92 of ''Tales of the Unexpected'', these two Nazi scientists with stereotypical accents had a hypno-ray mounted in the side of a large truck and were testing it on an entire town. The main character discovered that its effects were blocked by steel while trying on his old WWII army helmet during a fit of wishful nostalgia.
* In [[http://superdickery.com/images/stories/sceince/ac362.jpg the cover of Action Comics #362]], Clark Kent is attacked by a hypnotic ray from a device that looks like Superman's head and {{Mind Control}}led into hating his alter ego Superman.
* The Zorglonde (Zorglwave) in the ''ComicBook/SpirouAndFantasio'' comics. It allows the whole range from paralysing people at lower settings to making them highly suggestible, or completely brainwashing them and turn them into obedient automatons.

[[folder: Film ]]
* In ''Film/CloseEncountersOfTheThirdKind,'' the [[TheGreys Grey Aliens]] blast Roy Neary at close range and sunburn half of his face. SanitySlippage ensues.
* The Neuralizer from ''Film/MenInBlack''.
* Jafar's cobra headed staff in ''{{Disney/Aladdin}}'', which he uses on the Sultan repeatedly until Aladdin breaks it.
* In the second ''Film/{{Fantomas}}'' movie, the eponymous villain abducts a number of scientists and has them construct a HypnoRay gun. After the heroes thwart his plans and free the scientists, they use the gun to placate a pair of mooks he threw at them, but Fantômas himself escaped before they have a chance to subdue him.
* Used in ''Film/TheReturnOfCaptainInvincible''. Mr Midnight (Creator/ChristopherLee) steals it and uses it on ethnic minorities in America to force them to move to a particular town so that he can kill them off in one move.
* The L.O.O.K.E.R. gun from the 1981 film ''Film/{{Looker}}'' poses as a strobe-light gun, but really hypnotizes its victims so that they would lose all sense of time.
[[/folder]]

[[folder: Literature ]]
* The 3-D Hypno Ring from ''Literature/CaptainUnderpants''.
** A HypnoRay also appears in ''Literature/RickyRicottasMightyRobot'', by the same author.
* Not so much a ray as it is an audible tone, the main character of {{The Chronicles of Professor Jack Baling}} is on the receiving end of one of these at the beginning of Episode 2.
* In the earliest issues of ''Literature/PerryRhodan'', handheld "psycho-ray" weapons of Arkonide manufacture make for convenient plot devices in helping the protagonist set up his own small but powerful new nation-state on an Earth involved in a three-sided Cold War at the time. As amusing as some of the results may be, the abuse potential becomes obvious early on (an attacking fighter pilot that the user didn't ''mean'' to kill nonetheless dies from not snapping out of his trance after a hurried command to "pull up!" in time, causing his plane to stall out and crash with him still in it) and so it's perhaps unsurprising that this particular bit of phlebotinum later [[ForgottenPhlebotinum quietly drops out of sight]].

[[folder: Live Action Television ]]
* ''Series/BuffyTheVampireSlayer'' season six episode "Dead Things" features a dramatic subversion, at least as far as the comedic setting goes. Nerd supervillain Warren invents a mind control device and uses it on his ex-girlfriend, allowing the geek trio to dress her up as a French maid and generally be laughably adolescent about the whole thing. Then the story makes a swift plunge into darkness when [[spoiler: Warren commands his ex to give him oral sex; she comes out of the trance and accuses the trio of attempted rape, and is brutally killed by Warren when she tries to escape.]]
* The Mad Hatter from ''Series/{{Batman}}'' had one in his top hat, customized to look like a pair of eyes.
[[/folder]]

[[folder: Other Sites ]]
* ''Wiki/SCPFoundation'', [[http://www.scp-wiki.net/scp-2099 SCP-2099 ("Brain in a Jar")]]. SCP-2099 created a hypnotic lens that could be used to hypnotize people.
[[/folder]]

[[folder: Video Games ]]
* Much used in TelltaleGames's ''VideoGame/SamAndMaxFreelancePolice Season 1''. After all, the story is about MassHypnosis.
* ''[[VideoGame/DeBlob De Blob 2]]'' features the Hypno Ray, a planetary-sized hypnotic device under the control of Comrade Black powered by the color energy gathered by De Blob throughout the game. It's used once to take control of the residents of Prisma City. Apparently it also bleaches buildings.
* ''RatchetAndClankGoingCommando'' has one that works on robots only. Don't even think about using it on Clank.
* ''VideoGame/{{Pokemon}}'' has the move Hypnosis,which is a hypnotic suggestion that tells the opponent to go to sleep.
[[/folder]]

[[folder: Web Comics ]]
* Used in ''{{Concession}}'' where the sub-plot villains use mind control for villainy, although they state the possible real-life applications, to the chagrin of the mind control wielder.
[[/folder]]

[[folder: Western Animation ]]
* Stewie Griffin on ''WesternAnimation/FamilyGuy'' once tried to get on ''KidsSayTheDarndestThings'' to use one on the audience, but was defeated when Creator/BillCosby grabbed it and unknowingly [[HoistByHitOwnPetard used it on Stewie]].
* Used at least twice on ''WesternAnimation/TheAdventuresOfJimmyNeutron''. Once used by Beautiful Gorgeous to control SecretAgentMan Jet Fusion, but it failed when hundreds of people said the trigger words at the same time. Jimmy also used one to force his parents to think it was his birthday, but they [[TricksterMentor tricked him]] to [[AnAesop teach him a lesson]].
** They later try to {{justif|iedTrope}}y it: After Jimmy uses his HypnoRay to disable the MadScientistsBeautifulDaughter, his partner mentions that he didn't think hypnotism worked like that. Jimmy responds that the weak-willed are easily swayed by flashy special effects.
*** [[HoistByHisOwnPetard Ironically, she hypnotizes Jimmy in a later episode.]]
* The Hypnotoad on ''WesternAnimation/{{Futurama}}'' is the biological equiva- '''all glory to the Hypnotoad!'''
** Subverted in "The Lesser of Two Evils".
--->'''Fry:''' He must've used a sleep ray on me! Sleep rays exist in the future, right?
--->'''Leela:''' No.
--->'''Fry:''' Oh. Then I must've fallen asleep.
* Used for laughs in ''Disney/MeetTheRobinsons'', when Bowler Hat Guy attempts radio control of a frog. And later, a T-Rex. Bowler Hat Guy has trouble picking useful thralls.
* On ''WesternAnimation/{{WordGirl}}'', Mr. Big has a mind control ray which is used for farcical reasons - one of which was making everyone in town use huge words in order to occupy the heroine. Even the title character is not immune to this trope, but usually snaps out of it within seconds.
* In ''WesternAnimation/{{Dinosaucers}}'', Quackpot's "Joy Buzzer" is actually a ray gun with many uses. One of them is this, like when he [[HypnotizeThePrincess hypnotized Sarah]].
* In the ''WesternAnimation/{{Birdman}}'' episode "Empress of Evil", the title character's serpent-shaped head piece gives off one of these.
* ''WesternAnimation/HarveyBirdmanAttorneyAtLaw''
** Parodied in the "Turner Classic Birdman" episode.
--->'''Mentok:''' You're no longer in control of your mind, and your wings are missing too.\\
'''Harvey:''' I am no longer in control of my mind, and my wings are missing too.\\
'''Mentok:''' Uh, you don't have to repeat what I'm saying.\\
'''Harvey:''' I don't have to repeat what you're saying.
** Come to think of it, Mentok (and Francis X. Shado) both do this several times over the course of the series.
--->'''Potamus:''' Must... give... wallet... to... evil leprechaun...
* Happened once in ''WesternAnimation/ThunderCats''. The cast was saved by Snarf. ''Snarf''.
* Parodied in the ''WesternAnimation/SouthPark'' episode "The Return of Chef" where Chef is brainwashed by the Super Adventure Club to want to molest children. While the club leader explains the purpose of their group, they ask if the boys want to accompany them on their next trip. When they say no, he says maybe he should ask again and points a hypnotizer at them. When that attempt fails, he admits it doesn't work on everyone. They later explain to a psychiatrist that the Super Adventure Club convinced Chef that having sex with children was okay with a little thing that goes ''[[SayingSoundEffectsOutLoud whrrrrrr]]''.
* ''WesternAnimation/BuzzLightyearOfStarCommand'': Zurg's Zurgatronic Mega-Ray from the pilot movie, which is powerful enough to ''put the entire populace of a planet under at once''.
* ''Young Samson & Goliath'' episode "The Colossal Coral Creature". After the villain Darvo releases the title monster, he uses a "hypnotic ray" to control it.
