Mind Control Device

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. Plot Device, MacGuffin, and even a key part of a Very Special Episode.

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? Hope you like being a slave to the evil overlord.

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

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

That bracelet the street vendor gave you? Welcome to the most dangerous cult in the world.

See Mind Control, Mind Control Eyes and More Than Mind Control for the effects of these devices. May be the result of televising a person with the power of Hypnotic Eyes. Subtropes include: Subliminal Seduction, Hypno Ray, and Hypno Trinket. See also: Power Perversion Potential for the inevitable result in some viewers. May require the target to be Forced to Watch a transmission of some kind.

 * Shugo Chara 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.
 * Sailor Moon has had this in spades.
 * Artist Girl -- Pencil
 * Prince Endymion -- Queen Beryl
 * Chibi Moon (Rini) -- Wiseman
 * Shampoo of Ranma One Half 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 Magical Girl Lyrical Nanoha StrikerS. Implanted in by Jail Scaglietti so that someone like Quattro could override her thoughts should the need arise.
 * In two episodes of Science Ninja Team Gatchaman, the Galactor organization uses a mind-warping ray to turn innocent civilians into murderous, rioting mobs.
 * In Tsuritama Haru and Coco love to use their Mind Control Water Guns. Usually to make people dance.

Card Games

 * Magic the Gathering's 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.
 * Also various means of controlling your opponent's creatures, such as Helm of Possession.
 * The Steve Jackson card game Illuminati has the Orbital Mind Control Lasers as one of the cards.

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.)

 * The Marvel Universe has the Serpent Crown, a mind control device used to channel the power of Set, an Elder God. Many 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.
 * The Squadron Supreme limited series features the title heroes using a "behavior modification" device to brainwash convicted criminals (at first...). The ethical issues that arise are a source of friction for the team.
 * The Squadron themselves have been mind-controlled often enough that it's been Lampshaded both in comics (an issue of The Avengers claims that whenever they run into the Squadron, they assume that they're mind-controlled and about to attack until proven otherwise) and in games (the Marvel Saga rpg stats for Squadron members list susceptibility to mind-control powers among their weaknesses).
 * A post-Woodstock Superman adventure has him reporting on a series of rock concerts. This was at a time when some Moral Guardians genuinely believed rock was inherently hypnotic and that "the kids" would do whatever the lyrics said. Sure enough, mass violence broke out at show after show, seemingly prompted by the lyrics. Turned out a villain was using a Fiendish Device behind the scenes.
 * Issue #1 of The Awesome Slapstick has the Mediocritizer, which turns ordinary students into boring, unimaginative drones for the Overlord of Dimension X.
 * The G.I. Joe comic from Marvel had the Brainwave Scanner courtesy of Doctor Venom, as well as the S.N.A.K.E. armor.
 * Actually kind of subverted in the Donald Duck comic The Hypno Gun by Carl Barks, from which the page picture is taken. The titular hypno gun is in fact just a harmless toy gun that Huey, Dewey and Louie pretend to hypnotize one another with... however, Donald, overhearing them, thinks that it's a real hypno gun. Donald is, in fact so convinced that the hypno gun works that it actually does work on him, even if it doesn't work on anyone else.

Fan Works

 * Brox's Kiss, the hot pink short sword, in With Strings Attached. It works only on people of the opposite sex from the wielder.

 * Possibly, the pokeballs in New World. When a Pokemon is caught in one, they are mentally compelled to do whatever the trainer instructs them to do. It is implied that their name acts as an implanted trigger word.

Literature

 * The wiggly thing from the evil horses on The Fate Of The Fallen.
 * In the later Honor Harrington novels, a rogue planet of eugenicists called Mesa develops a nano-virus that is capable of compelling behavior out of its victims. It is used several times to stage assassinations and get rid of key enemies and is notable 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 Captain Underpants.
 * in Jack Chalker's G.O.D. Inc. series, the Hypnoscanner is shown to have serious Power Perversion Potential.

Live-Action TV

 * Star Trek Voyager. 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.
 * Star Trek does it for real on occasion. In Dagger of the Mind, a "hospital" basically zombifies people with a hypno-spinny-thingy. Trying to remember what happened to you, let alone tell others, causes increasing pain and eventually death. However, brainwashing in Trek usually takes the form of More Than Mind Control, psychic manipulation, etc.
 * And then there's the Star Trek the Next Generation episode "The Game" where a simple Puzzle Game takes over the psyches of the crew. (Think of it as an allegory of what would happen if Angry Birds or Zuma was created with evil intent -- if such a thought really is a stretch.)
 * Several different varieties turned up during the original run of Doctor Who; sometimes it was even the Doctor himself using them.
 * Also Cybus EarPods and the Archangel Network in the new series. Also, take a look at the Silence ... wait, where was I? Cybus and Archangel, right.
 * If Karl Rove gives you a cookie, don't eat it.

 * Super Force had numerous episodes where the villain of the week used one or another of these.

Video Games

 * Heroic version: Little Kings Story for the Wii from the makers of Harvest Moon features a little boy finding a magical crown that commands the obedience of all around him.
 * Command & Conquer features mind control with Yuri in Red Alert 2 and more elaborately in the Yuri's Revenge expansion pack. Units change side (and color) and start fighting against you so long the mind control guys are alive and not controlling someone else instead. Furthermore there are two kinds of mind control: direct, puppet master mind control that involves units temporarily commandeering others and less specific, broadcasting Psychic Beacon mind control culminating in the Psychic Dominator doomsday devices that

 * 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 Robot Rebellion.
 * You, the Brainina Jar in Cortex Command, use this to control units. Good thing too, since so far, the AI is pretty darned dumb.
 * In Video Game/Mabinogi, monsters occasionally drop Fomor scrolls, which Fomor use to control creatures. These may be why something as simple as a freaking fox wants to beat the living daylights out of you
 * The in The World Ends With You  Luckily for  negate the mind control, since
 * The Sensorama from Gadget: Past as Future.
 * Terra was a victim of this in Final Fantasy VI. To go into detail, sometime after she was kidnapped by the Empire as a child, Kefka (presumably with Emperor Gestahl's permission), developed a slave crown from Magitek technology which, as the name implies, sapped Terra's free will and emotions (there was also some cut dialogue that was still in the data script that indicated that Terra was an unwilling victim of this procedure). Afterwards, she burned fifty Imperial Soldiers alive all because Kefka told her to do so and she simply couldn't refuse due to the slave crown.
 * The from the Assassin's Creed series seem to have this among their powers.
 * In the Dungeons and Dragons Forgotten Realms game Curse of the Azure Bonds, the magic tattoo version of this from the novel Azure Bonds (see Literature) has apparently been licensed out to various evil organizations.

 * Terror From the Deep replaces psionics with a strange technology called "Molecular Control", which uses mind control implants to direct the aliens by some unknown means.

Web Comics

 * Mutant Ninja Turtles Gaiden 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 the cartoon.
 * The "slaver wasps" from Girl Genius.
 * So-called "turn-masks" in A Tale of Fiction make monsters and magique-wielders fight for the tyrannical DUF when placed upon their faces.

Web Original

 * Avalon Tech Enterprises has a Therapy Room in Arcana Magi.
 * Dr. Insano has apparently also built a "Neuraliser" that sends messages like "Obey Dr. Insano". It has never been shown in operation, though, but that didn't stop the fandom from having a field day with it. There is also Linkara's brainwashing/subliminal message machine-thingey.

Western Animation

Played for laughs but still a WHAT THE HELL HERO? moment.
 * WITCH: Appeared in both episodes, "Walk This Way", and "G is For Garbage", as a mystical horn that hypnotized its victims into trance-marchers who did anything they could by those who possessed it.

Eventually, Lilo learns the error of her ways when she finds that Murtle has imprisoned most of the townspeople for the slightest infractions.

 * Birdman episode "Empress of Evil". The title villain uses her serpent-shaped mind-control headpiece.

Real Life

 * Project MK-ULTRA.
 * A popular Conspiracy Theory holds that blood drives are a "cover" for implanting mind control chips, and the secret was blown when someone ran a stud finder over his arm and found the chip. The Myth Busters showed that you can detect a microchip implanted under the skin with a stud finder (they borrowed a dog with an ID chip to practice), but found no chips in either Jamie or Adam after a trip to the Red Cross.
 * Well of course they didn't, they were being mind-controlled not to!
 * An episode of Through the Wormhole showed experiments that include applying a magnetic field to certain parts of the brain reduce the ability to judge right from wrong.
