->''"Black Mage has got some sort of screaming demon background noise reverb thing going on with his voice. I think he just wants attention."''
-->-- '''Fighter''', ''Webcomic/EightBitTheater''

Evil characters get a lot in the way of cool toys, [[BadPowersBadPeople powers]], and even [[SpikesOfVillainy wardrobe]] [[EvilCostumeSwitch options]], but one of the coolest additions a sufficiently evil and powerful character gets is being able to speak with the Voice of the Legion.

The character's voice gains a reverberating [[PowerEchoes Echo]], sometimes a completely different voice(s) speaking in tandem and just ''slightly'' out of sync, almost mathematically calculated to just be able to distinguish one another. The character's voice will often [[PowerMakesYourVoiceDeep drop a tritone or a full octave]] and become [[EvilSoundsDeep deeper]], though even a falsetto can become jarringly creepy with the reverb alone.

The cause can be anything from channeling spirits, a FreakyFridayFlip situation, DemonicPossession, or an EldritchAbomination (or its servants) deigning to [[AliensSpeakingEnglish speak in English]] rather than the BlackSpeech, except their accent bleeds through (like blood from the throats of so many virgin sacrifices) and makes the English they speak in sound positively scary and nightmarish. This is distinct from the CreepyMonotone in that the character may not speak in a monotone, but the voice ''itself'' is creepy.

If the individual speaking is possessed, this may be an indication that there are ManySpiritsInsideOfOne. (Or it could just be one with a really creepy voice.)

Heroes or good characters ''can'' use this power, DarkIsNotEvil, after all, and the possessing/channeled spirits might not be evil. Often, a good character will get this from performing a FusionDance with another good one, rather than a DemonicPossession. {{God}}s, especially the Abrahamic one, are often portrayed with such voices, as well. Either way, this character is not to be trifled with.

In {{Manga}} and ComicBooks, this is represented with [[PaintingTheMedium stylistic indicators]] (e.g., using very large, heavy strokes) used in SpeechBubbles for "monster voice".

This trope is named for IAmLegion, the mental version. Sometimes this overlaps with VoicesAreMental. May contain VaderBreath, may be used when HearingVoices. Contrast SpeakInUnison, where many people speak as one. Compare GutturalGrowler, EvilSoundsDeep, and EvilSoundsRaspy.


[[folder:Anime & Manga]]
* In ''Manga/BirdyTheMighty Decode'': Birdy is a {{Human Alien|s}} galactic superheroine who merges her body with Tsutomu, a typical high school boy who she [[AccidentalMurder mistakingly kills]] during an intense battle with an alien criminal. Over time, Tsutomu's mind begans to claim dominance over Birdy's, his memories eventually melding with hers. This leads to Tsutomu inhabiting Birdy's body instead of his own for a short period, resulting in his (and her body's voice) speaking in sync of each other. However, no one else can hear this since this is in his own thoughts.
* Parodied in ''Manga/BoboboboBobobo'' when Bo-bobo, Don Patch, and Jelly Jiggler merge to form Bo-Patchiggler. He talks in all three voices, just not at the same time. All the other Bo-bobo Fusions, however, only speak with one voice.
* ''Franchise/{{Digimon}}'' characters performing a FusionDance speak with the voices of both entities involved in the process (though each individual will speak on his/her own at times).
** There are exceptions, of course. In the third season this trope only applies to the American dub, as the Japanese version has the fused character speak in a third and singular voice.
* In ''Anime/DragonBallKai'', Goku's voice turns slightly demonic for a short while just as he turns Super Saiyan for the first time.
** Any Fusion character from ''Anime/DragonBallZ'' (except the Kais that is), which might be the originator of this variation.
** And although the Portuguese dub may not be perfect, one thing they did well was giving Piccolo this kind of voice, suits him very well considering his status as alien and former status as "Demon King".
** The Greek dub takes this trope to the extreme: almost every "evil" character, like King Piccolo, Piccolo Jr., Nappa and Vegeta (But not Raditz), Freeza, Cell, Babidi, Buu, the Ginyu Force, all Namekians (even though they're good) have this voice effect applied.
*** It gets a lot more confusing, actually. A few times, Vegeta's voice actor changed, and he isn't given the effect (guess it didn't work well with his new voice?) but it came back as soon as the old actor came back.
*** Tien's voice was also given the effect a couple of times, even though he didn't have it to begin with.
*** And in Dragon Ball GT and the movies, it's missing. Completely.
** Also averted in ''Z'''s Hungarian dub, save for a single sentence (Gotenks naming himself/themselves). They actually attempted it, but the actors found it too hard to do, so the fusions had only one voice. In ''GT'', however, they pulled it off.
* ''Anime/DragonBallSuper'' gives us the example of [[spoiler:Fusion Zamasu]] in the Future Trunks Saga after Black and [[spoiler:Zamasu fuse with Potara earrings. It's his own voice doubled because Black is just another him in the body of another Goku.]]
* ''Anime/YuGiOh'': Whenever Marik possessed somebody, his voice would overlay theirs. This later happened to Marik himself, after his SplitPersonalityTakeover. Normal Marik has a high, nasal quality. Dark Marik's voice is lower and snarlier, and overlaid by at least two or three others, some lower, some higher. Throw in the constantly stretching face, and you get the impression that something even worse than our resident villain is fighting to get out. Note that this is exclusive to the 4Kids dub while in Japanese, Marik just took on an eviler tone.
* When Chrono from ''Manga/ChronoCrusade'' begins to transform into his [[OlderAlterEgo true form]], his voice takes on an ethereal-sounding echo. (However, once he transforms his voice sounds normal, only deeper.) This is particularly noticeable in the second episode, when he's trying to transform without Rosette releasing the seal.
* The [[NightOfTheLivingMooks Mariages]] from ''AudioPlay/StrikerSSoundStageX'' all speak with an echo, being [[NinjaPirateZombieRobot Cyborg Zombie]] {{Super Soldier}}s that possess a HiveMind.
* Lots of examples in ''Manga/InuYasha''; standard anime monster speech.
* The original ''Anime/MazingerZ'' had Baron Ashura, who would speak in a female voice when only its female half was visible, a male voice from the other side, and both at once when both sides of its face were visible.
* In ''[[Manga/FullmetalAlchemist Fullmetal Alchemist: Brotherhood]]'', there's The Truth, Hulk!Envy, Pride, and Father toward the end of the series.
* In the late ''Manga/RanmaOneHalf'' manga, the cursed form of Rouge is the Vedic demon Ashura, who got three faces. The three mouths tend to talk simultaneously... though they don't always agree..
* ''LightNovel/{{Slayers}}'': The Lord of Nightmares.
* ''Anime/PokemonTheFirstMovie'' touches on this trope for a few lines, though there's a somewhat mundane explanation: Mewtwo is communicating telepathically with the heroes as himself while, at the same time, the possessed Nurse Joy is speaking his dialogue aloud. The sound of their combined voices, particularly when both of them respond to a failed attack with "child's play", makes for one of the creepiest moments in the movie.
* ''Manga/DGrayMan'' had [[spoiler:Jasdevi speak in this fashion when the two combine]].
* In ''Anime/TransformersEnergon'', the Alpha Quintesson's fifth, unseen "true face." [[spoiler: It sounds like many voices talking at once because it is -- "the voice of all those lost" when Unicron made a meal of his solar system.]]
* When Manga/{{Claymore}}s begin to [[SuperpoweredEvilSide Awaken]] they start to speak like this. Yoma and Awakened Beings speak with an Evil Echo whenever they're not disguised as humans.
* One of a the first of a series of horror stories stories from the manga "Gakkou de Atta Kowai Hanashi" had the main character, Ootsuka Kaho, and her three friends receive a cursed text message. When two of her friends suddenly disappear, Ootsuka begin to panic fearing she will be next, but is calmed by her remaining friend, Maaya, who reassures her that the other two will be found eventually. When Ootsuka, though her texts, finds Maaya on the roof, she notices her talking in a completely different voice, which then become many voices. In a TwistEnding, it's revealed that it was Maaya who was sending her the cursed texts. Her negative emotions were absorbed and amplified by malevolent spirits, covering her body in misshapen faces, including Ootsuka's two missing friends who were jealous of Ootsuka's relationship with a popular boy they were attracted to.
* ''Anime/YuGiOhGX'' - [[SuperpoweredEvilSide Supreme King Judai/Jaden]] has this in the English dub.
* [[EvilDoll Kuruku]], a living puppet, has this as his usual speech pattern in the second ''Manga/{{Unico}}'' movie. Taken UpToEleven when he gets angry, though.
** And given his backstory, [[FridgeBrilliance it makes perfect sense]] - he is, after all, [[spoiler: a puppet that came to life after being cast aside. As such, he'd have been voiced by many people at some point prior to being thrown away]].
* Buggy in the 4Kids dub of ''Manga/OnePiece'' would shout like this whenever he was angry.
* In ''Manga/TokyoGhoul'', one of the effects of the [[CannibalismSuperpower Kakuja]] form is an echoing, distorted voice. The CreepyChild-like Eto speaks like this normally, one of our early clues that there's some very strange about her.
* ''Manga/FairyTail'': Lullaby in the anime.
* Eren Jaeger from ''Manga/AttackOnTitan'' sometimes sounds like this when speaking from inside his titan form in the anime version. Thank god no one else seems to be able to hear him.
* Tetsuo talks like this in the Streamline Pictures dub of ''Manga/{{Akira}}'' when he mutates into the giant mass after losing control of his powers, in the Pioneer dub his voice remains normal until he tells Kaneda to get out of his body while he still can and screams in pain.

* Alpha One of ''ComicBook/TheMighty'' has this by showing a unique outline in his speech balloons.
* In ''ComicBook/{{Preacher}}'', Jesse's words are in red when he's using [[CompellingVoice the Word of God]]. Except when the typographer slips up, which happens.
* ComicBook/TheSpectre, who typically speaks in dripping green speech balloons.
* [[AxCrazy Jei-san]] in ''ComicBook/UsagiYojimbo'' [[spoiler: and anyone who is possessed by him/it]].
* The ''ComicBook/XMen'' villain [[Characters/XMenAcolytes Exodus]] had this going on for his early appearances in the '90s, having speech balloons that were always purple-bordered, and also yellow-colored when using his powers. Like many interesting character tics from that period, it was either dropped or forgotten about as his post-90s speech balloons have been of ordinary color and border.
* Franchise/SpiderMan's longtime enemy ComicBook/{{Venom}} (see below) is occasionally mentioned to have this, sometimes illustrated by black speech bubbles with distorted outlines.
-->'''Spider-Man:''' That weird-double sound when they talk through the suit. Like somebody yelling into a loudspeaker...

* In ''Fanfic/CodePonyEvolution,'' X.A.N.A (who is SuddenlyVoiced) is implied to have every kind of scary voice at once.
* Played straight in a written fanfiction no less. [[http://www.fanfiction.net/s/4695538/1/Angel_of_Massacre Samael/The Boy in the Theater]] speaks in an alternating Bold and Italic accent. [[http://www.fanfiction.net/u/1053449/Numbnut10 The Author]] has complained about the difficulty involved.
* B-3-K, of ''Roleplay/YukariIsFree.'' Portrayed in written form via different colors of text.
* In ''Fanfic/ChildOfTheStorm'', Harry develops the ability to do this after chapter 44, with two voices speaking at once, indicated by italicised writing. It proves to be one of the very things that can get the Weasley Twins to shut up instantly, something [[LampshadeHanging noted]] by Hermione. At first, however, he can't control it and it rather unnerves him. About 10 chapters later, he gains the ability to use it at will. The other voice is described as sounding like Harry, but older and considerably more authoritative.
** Further confusing matters is the fact that in chapter 58, [[spoiler: the Phoenix or possibly Lily Potter - no one's entirely sure]], speaks through him, the text being rendered in bold italics.
** When [[spoiler: Chthon]] possesses someone and speaks through them, his voice is a) creepy, b) constantly subtly shifting, c) makes reality scream. [[ObviouslyEvil Needless to say,]] he's the BigBad.
* In the ''Franchise/MyLittlePony'': ''[[WesternAnimation/MyLittlePonyFriendshipIsMagic Friendship Is Magic]]'' / ''Series/DoctorWho'' Crossover ''FanFic/TimeLordsAndTerror,'' the G1 villain known as the Smooze is [[DarkerAndGrittier reimagined]] as [[AdaptationalBadass The]] [[EldritchAbomination SíMüz]], a being so infused with unreality that its voice is described as
--> ''a billion different voices in a billion different tones, a low flanging and echo present in it's ominous timbre.''
** This is represented via text with bold italicized block capital letters colored red.
* In ''Fanfic/HaloCombatDeformed'', the Master Chief speaks in a deep, satanic rumble whenever he gets very angry.
* In ''FanFic/InnerDemons'', when [[BigBad Queen!]][[FaceHeelTurn Twilight Sparkle]] succeeds in [[OneWingedAngel transforming into an Alicorn]], it's commented on that her voice sounds like two voices speaking at once.
* A poltergeist girl in ''Fanfic/CalvinAndHobbesTheSeries'' has this when angered.
* In ''Fanfic/PokeWars'', Giratina's voice is described as "dozens of voices speaking in some unholy chorus and echoing from the darkest corners of the world".
* In ''[[Fanfic/APonyOutOfPlace Flames and Twilight]]'' after Flare and Nightmare Moon [[FusionDance become]] Knightmare Nova he has the voices of Flare and Nightmare Moon speaking at once.
* Kenny's voice become like this in the first story of "Fanfic/TheMysterionMythos" after [[spoiler: he finally joins with The Shadow]].
* In ''Gensokyo 20XXV'', Reimu does this when she talks to Yume Ni in everyone's voices (including her own), after stabbing the latter with a pair of scissors. This is indicated by the use of WebOriginal/{{Zalgo}} text.

[[folder:Films -- Animation]]
* Played with in the Disney film ''Disney/ChickenLittle''. The title character is abducted and put in a black room where a sinister bunch of eyes yells at him in a deep voice... and then a woman is heard telling said bunch of eyes to "turn off the Big Voice." A door opens and we find out that the owner of those eyes is about the size of Franchise/{{Kirby}}.
* One of the experimental voices of God in ''WesternAnimation/ThePrinceOfEgypt'' involved using every voice Moses had ever heard in life at once. After creating "many excellent voices for Satan" and apparently running out of time they dropped all the special effects in favor of [[TalkingToHimself just having God use Moses' voice]] (though there is a kind of whispery after-affect audible).
* [[WesternAnimation/{{Coraline}}The Other Bobinsky,]] towards the end of the film. "Not even that...'' anymore."''
* Aisling briefly speaks with this in ''WesternAnimation/TheSecretOfKells'' as she's attacked by Crom Cruach.
* Literature/TheMysteriousStranger in ''WesternAnimation/TheAdventuresOfMarkTwain'' is voiced by a male and female speaking simultaneously.
* In ''WesternAnimation/{{Care Bears Movie II|A New Generation}}'', the villain Dark Heart speaks this way occasionally.

[[folder:Films -- Live Action]]
* Used for the voice of Drazuul in the film ''Film/TheGamersDorknessRising''
* Regan from ''Film/TheExorcist'' might be the ur-example of this trope.
* Also used in ''Film/TheExorcismOfEmilyRose'' when the priest orders the possessing demon to name itself. Several voices answer back, in different languages, each overlapping. One of them actually identifies itself as Legion.
* ''Film/{{Ghostbusters 1984}}'': "There is no Dana, [[ThatManIsDead only ZUUL!]]" Immediately {{lampshade|Hanging}}d: "What a lovely singing voice you must have".
* Blackheart from ''Film/GhostRider'' because he's possessed by hundreds of evil souls.
** He even says the line "IAmLegion, for we are [[LargeHam MAAAAANNNNNNNYYYYY]]!"
** Blackheart also has this before he gains the thousand evil souls; however, he originally only has the reverberating echo effect on his voice. It is not until the end of the film that this effect is enhanced, first used with the additional emphasis when he says the line above.
* Theatre/{{Hamlet}}'s father, in Creator/KennethBranagh's movie, has a Darth Vader rasp, a deep voice, and there's a mike (not shown, but you can hear it) inside his helmet. Possibly done to show just how scary Creator/WilliamShakespeare meant it to be when Hamlet is visited by his father's ghost.
* Creator/PeterJackson's ''Film/TheLordOfTheRings'':
** "In place of a Dark Lord, you would have a queen! Not dark, but beautiful and terrible as the dawn! Treacherous as the sea! Stronger than the foundations of the earth! All shall love me, and despair!" This scene is almost LargeHam levels of {{Narm}} in the movie.
** Also Gandalf's voice overlaid with Saruman's in the second film, purely for the purpose of confusing the viewer as to which character is speaking (as his face is obscured). Both the overlayed voices imitate each other's style of speech for extra confusion.
** When Gandalf speaks the Ring verse in Rivendell, which is only seen in the extended cut of the film, but present in the book.
** The Mouth of Sauron from the extended version of ''Return of the King''. As the envoy for the undisputed lord of Darkness across all of Middle-Earth, the Voice of Sauron's actual voice is six kinds of creepy -- a hammy Russian accent, turned up to 11 and distorted considerably.
** Sauron himself gets a few lines of this in the first film, either when speaking as the Ring (appropriately, in BlackSpeech) or when addressing Frodo directly: "YOU CANNOT HIDE. I SEE YOU. THERE IS NO LIFE IN THE VOID. ONLY. DEATH." Charmed to meet you too, sir.
* In ''Film/HowardTheDuck'', Dr. Jenning often has this sort of voice after the Dark Overlord possesses him (especially when he and the main characters are conversing at the truck stop).
* Creator/DavidLynch, in his film version of ''{{Film/Dune}}'', depicts the Voice used by the Bene Gesserit to control minds in this way. It gets especially creepy when Alia does it, being not yet 7 years old at the time.
* ''Film/XMenApocalypse'': En Sabah Nur sometimes sounds like he speaks with multiple voices, and Creator/BryanSinger has explained that this is the result of the character absorbing many "souls" throughout his lifetime.
* [[TheGrimReaper The Angel of Death]] in ''Film/HellboyIITheGoldenArmy''. Interestingly, one of its voices sounds a lot like [[Film/PansLabyrinth The Faun]], both of whom were played by Doug Jones.
* [[spoiler:Tia Dalma]] in ''Film/PiratesOfTheCaribbeanAtWorldsEnd'' has this voice when she turns into Calypso.
* ''Film/ParanormalActivity'': A mockumentary, Blair Witch-like movie about a guy, Micah, who videotapes his girlfriend, Katie, as she is repeatedly tormented by a vicious unseen "demon" that has haunted her since her childhood. The attacks get progressively worse until the demon drags her from her bed and bites her. Right after the incident, she hysterically pleads to get out of the house. When making preparations for leaving, Micah finds Katie in bed, noticeably calm and wishing to stay despite her earlier pleas. When Micah leaves the room in confusion, Katie (in one of the scariest moments in the movie) whispers "I think we'll be [[foldercontrol]]

[[folder: OK now ]]
", her voice layered with a chilling undertone, and then smiles eerily, suggesting she has been possessed by the demon. [[spoiler: This is boosted by the fact that they die that very night, or [[RevisedEnding Micah anyway]].]]
* ''Film/FiveGirls'', appropriately used for people possessed by Legion.
* Good ol' Satan from ''Film/TheLastTemptationOfChrist'' speaks in quite a few voices, one of them being this.
* In the ''Film/{{Stargate}}'' movie, Ra's voice definitely sounds like it's coming from the bowels of Hell, contrasting with his innocent {{Bishonen}} face. The TV series, of course, uses the effect also.
* Dr. Emilio Lizardo/Lord John Whorfin sounds this way in ''Film/TheAdventuresOfBuckarooBanzaiAcrossTheEighthDimension''.
* ''Film/TheWizardOfOz'': '''I AM OZ, THE GREAT AND POWERFUL! WHO ARE YOU?!'''
* ''Film/{{Oblivion|2013}}'': [[spoiler:During the final confrontation, "Sally's" voice is layered with a very robotic voice]].
* ''Film/TheLastWitchHunter'': the Witch Queen has a serious case of multiple voices, ranging from an odd echo to four or five speaking at once.

* A rare literary example of the tandem voice occurs in ''Literature/PerdidoStreetStation'', where the representative of the demons appears as a perfectly normal human man with a perfectly normal voice... followed on a slight delay by the faint and far more unsettling voice of his true form.
* An apparent literary example would be [[/folder]]

[[folder: [[Literature/Discworld Death ]]
** [[http://www.youtube.com/watch?v=u9bJgZ5y5jU Theatrical example!]]
** An arguably more creepy version is actually a subversion. The Auditors of Reality do not have voices as one would think of them. Instead, they simply alter the nature of reality such that ''they have already spoken''. The words appear fully formed in the mind.
*** Which is represented as their dialogue being without speech marks. Unfortunately this was replaced with more generic italics in ''Discworld/ThiefOfTime''.
** The voice of the BigBad in ''Discworld/TheAmazingMauriceAndHisEducatedRodents'', like the Auditors', goes directly into the mind without entering the ears:
--->It was all hisses, and it slid into the mind like a knife.
*** Death's voice is often described as going to the brain while skipping the ears completely. The Auditors don't do even that. You just suddenly remember that something was said moments ago.
** In ''Sourcery'', the Archchancellor's Hat plays this trope straight, which is appropriate for something that derives its intelligence from its hundreds of previous wearers.
** In a variant from ''Discworld/{{Maskerade}}'', Agnes demonstrates her ability to sing multiple notes simultaneously.
* In Dennis L. [=McKiernan's=] ''Mithgar'' series, all necromancers must deal with this when trying to find out information. Nothing is hidden from the dead, but whenever a corpse is raised hundreds of spirits try to speak through it, and only a necromancer's intimidating power can force the voice he wants to speak just ever so much more loudly. Considering [[BodyHorror what most necromancers]] [[ColdBloodedTorture are like]], this is hardly a surprise.
* In Jonothan Stroud's ''Literature/TheBartimaeusTrilogy'', specifically the first book ''The Amulet of Samarkand'', the demon Ramuthra's voice sounds as if spoken by a large group.
* Raezazel the Cunning from the ''TabletopGame/{{Warhammer 40000}}'' novel ''[[Literature/GreyKnights Hammer of Daemons]]'' is said to speak with a hundred voices at least.
* In a non-demonic example, the two-headed Puppeteers in Larry Niven's Literature/{{Ringworld}} series are the only species ''physically able'' to speak their native language, because all other races in Known Space only have one throat.
* The Goddess Verra in the ''Literature/{{Dragaera}}'' series. Vlad compares it to two identical voices speaking slightly out of sync.
* Soulcatcher from ''Literature/TheBlackCompany'' speaks in the voices of all those whose souls she's caught.
** Although usually only one at once, each with regular human intonation; listeners still get freaked out by the rapid switching of gender, age and mood, though.
* Used by the Raggedy Man in Stephen King's ''Literature/{{Cell}}''. The Raggedy Man himself is [[spoiler: the psuedopod of a massive hive-mind]], and can only speak through other characters.
* The {{Silico|nBasedLife}}ids in Creator/SergeyLukyanenko's ''Literature/LineOfDelirium'' are floating columns of rock which natively communicate via modulated electromagnetic fields. Since most races communicate vocally, the Silicoids have learned to vibrate their entire bodies to produce sound, turning them into huge speakers. Due to this effect, a Silicoid sounds as if an entire choir is speaking. This is a non-evil example, though.
* In ''[[Literature/TheBelgariad Polgara the Sorceress]]'', an adolescent Polgara shows off at one point by singing with three voices (and three different vocal ranges) at once.
* Done in a CreepyAwesome scene in ''[[Literature/TheQuantumThief Fractal Prince]]'' where Matjek Chen Prime assumes his true form:
-->The Vir dissolves around them. Matjek assumes his Prime aspect, the voice of a billion gogols, the Metaself, the keeper of the Plan, the Father of Dragons.
* A somewhat Inverted example occurs in Elizabeth C. Mock's ''Literature/TheChildrenOfMan'' series, in which the Oracle of Nikela speaks like this when delivering her prophecies, despite the fact that in that state she is the direct mouthpiece of Lior (this world's equivalent of the Christian God).
* In ''Literature/FancyApartments'', when Carr pushes his bond with Fancy to the max, his voice takes on a reverb. He doesn't know what to make of it; but tries his best to ignore it, having more important problems to deal with.
* The [[OurLichesAreDifferent lazar]] of ''Literature/TheDeathGateCycle'' speak with two voices, slightly out of sync- the body's voice speaks first, and then the soul's follows more quietly about a word behind. Living people who interact with them generally find the effect incredibly frustrating and unsettling.
* In ''Literature/GorgoTheOgre'' one of the Black Ogres speaks to this effect as he has two heads talking at the same time.
* In ''Literature/TheZombieKnight'', a reaper servant's [[SuperMode hyper state]] causes the reaper's and servant's souls to temporarily fuse, causing them to speak an a one-physical-one-mental double voice.
* In ''Literature/SecondApocalypse'', Kellhus can do vocal tricks when playing himself up as a prophet. When one of his "imprompta" sermons kicks into high gear, an audience member notes how his voice splits, and he seems to be speaking as a chorus of voices.

[[folder:Live Action TV]]
* In ''Series/{{Smallville}}'', {{ComicBook/Darkseid}} does this frequently, although EvilSoundsDeep is more prominent.
* ''Series/BuffyTheVampireSlayer''
** Invoked on more than one occasion, including Willow in the midst of her black magic rampage, Caleb after merging with the First, and The Anointed One, who being a [[CreepyChild child]] had a high regular voice.
** A non-evil version happens when a ritual grants Buffy the [[ThePowerOfFriendship combined power]] of the Scooby Gang, she speaks with all four of their voices simultaneously.
* The Goa'uld from ''Series/StargateSG1'' can do this at will, along with GlowingEyesOfDoom for the sole purpose of intimidation. The idea behind is that they're manipulating the vocal cords directly rather than talking indirectly through their host's brain. They ''can'' talk normally, and do so at length to infiltrate their enemies' strongholds. For fun too, I guess.
** The Tok'ra also do this, but only so people can tell if it's the host or symbiote speaking.
** The Goa'uld seem to see their unique vocal pattern as symbolic of their claims of being [[AGodAmI gods]]; hence Baal (who unlike most Goa'uld doesn't fall for his own propaganda, instead being rather flippant about his "godhood") being prone to speaking normally to people who know he's not a god, reserving the Voice of the Legion effect for intimidation and for maintaining the illusion among his true believers.
** The effect changes over the years too. At first it was harsher than the movie's smoother version, perfect for Apophis but ''not'' so much Hathor. Later, the voice wasn't deepened as much by it.
* ''Series/StargateAtlantis'': The voice of the Wraith have a bit of reverb too. Wraith queen's mind control also echoes in the victim's head.
* ''Franchise/StarTrek'': "'''WE ARE THE BORG.'''" Of course, this is because they actually ''are'' all talking at once. An individual drone gets juuust a bit of 'electronic'-ness added.
** Becomes literal when the Borg abduct and assimilate Jean-Luc Picard; renaming him [[MeaningfulRename Locutus of Borg]]--roughly, The One Who Speaks for the Borg.
* The new ''Series/DoctorWho'' has an excellent example of this appear in the Season 2 two-parter "The Impossible Planet/The Satan Pit". It is played very effectively. WE ARE THE LEGION OF THE BEAST!
** Quite literally, since an {{Expy}} for {{Satan}} is mind-controlling a legion of [[KeystoneArmy service industry workers]] who share a [[WhatCouldPossiblyGoWrong single consciousness]] that has to be orbiting over an EldritchLocation.
** The Absorbaloff has this too, which makes sense, since his entire schtick is that he absorbs other people into him.
** The Doctor is particularly disturbed by a life form that simultaneously copies your words in "Midnight".
** {{Subverted| trope}} in "In the Forest of the Night" in which little girl Maebh gains a deeper, multitracked voice when she's speaking for the ultimately benevolent trees.
* Many villains and monsters in ''Franchise/PowerRangers'' have some kind of effects added to their voice. Your average MonsterOfTheWeek will simply add a bit of growliness In contrast, ''Franchise/SuperSentai'' only rarely uses this trope, with most villains and monsters speaking in normal human voices. Desumozorlya from from ''Series/BakuryuuSentaiAbaranger'' is a rare counterexample.
* In contrast to ''Franchise/SuperSentai'', ''Series/{{Ultraman}}'', when aliens speak, applies effects to their voices, especially the reverberating laughter of [[DittoAliens Baltan]]-seijin.
* Arch-villain Sylar occasionally talks like this on ''Series/{{Heroes}}'', although there's no real plot-related reason why he does. The [[WordOfGod writers have admitted]] they put it in just because it sounds cool.
** Eden [=McCain=] would also do this when influencing people with her ability. A clear ShoutOut to Creator/DavidLynch's ''{{Film/Dune}}'' and the [[MoreThanMindControl Voice]].
* In ''Series/TrueBlood'', Sookie hears people's thoughts with this effect. This gets specially creepy when she tries to read [[spoiler: Maryann's mind]] where CreepyMonotone and GratuitousGreek are added to said effect.
* In the "Small Worlds" episode of ''Series/{{Torchwood}}'', the fairy things sound like multiple voices as once whenever they talk.
* Used for the disembodied voice of Satan in one ''Series/TheWhitestKidsUKnow'' sketch. It rather helps the comedic effect of the Lord of All Evil reprimanding a demon that "You know our first priority is to entertain."
* ''Series/StarTrekDeepSpaceNine'': When [[spoiler:Gul Dukat]] becomes the Emissary of the Pah-Wraiths during the GrandFinale so that he can destroy the Alpha Quadrant and gains superpowers in the process, his voice becomes significantly deeper and echoes.
* The 2014 Halloween episode of ''Series/SaturdayNightLive'' includes a sketch where Halloween store owner Geoff has been possessed by the demon Galadriel.
* Occurs in an early episode of ''Series/MalcolmInTheMiddle'' when the boys steal back their TV from Lois, who's trying to interrogate them for allegedly ruining her dress.
-->'''Lois:''' [[GoToYourRoom Go to your rooms]]...'''NOW.'''
* ''Series/TheFlash2014'':
** Barry learns to do this to disguise his voice by vibrating his vocal cords really fast. This is particularly necessary with Iris, with whom he grew up, and the cops he works with (those who aren't in the know). Usually, he also vibrates his face to obscure it, realizing that ClarkKenting is unlikely to protect him.
** The first three {{Big Bad}}s ''all'' use this trick, to the point that the second two are voiced by [[CastAsAMask completely different actors]] when suited up, keeping both the characters and audiences guessing about their real identities:
*** The Reverse Flash does this near-constantly, except he makes his voice sound [[EvilSoundsDeep downright demonic]] and gives himself glowing red eyes for good measure.
*** Zoom can make his voice even deeper and more echo-y than Reverse Flash. Whenever he's in full costume, he sounds like Creator/TonyTodd with added distortion.
*** Rounding out a trio of evil speedsters, Savitar's armor gives a metallic edge to the voice of whoever's wearing it.
** When Caitlyn Snow taps into her metahuman powers, everything she says is underscored by a distorted, inhuman whisper, marking a transition into an evil "Killer Frost" persona. Interestingly for this trope, it seems both involuntary and exclusively tied to her powers; if she goes long enough without using them, her speech will revert to normal. It's notable that when Killer Frost [[spoiler:makes a HeelFaceTurn in the season 3 finale ''without'' fully reverting to Caitlyn, the voice is one of the aspects that she loses.]]
* When ''Series/{{Arrow}}'' introduces Ragman in Season 5, he talks like this when using his powers. It's creepy, which even he admits.
-->'''Ragman''': [[LampshadeHanging Is it the whispers? They just do that, I don't know why.]]
* ''Series/{{Supergirl 2015}}'': Reign the Worldkiller speaks with a reverbing echo. Combined with her mask, this prevents the others from recognizing her as Samantha Arias.

* Used a lot in Black, Gothic and Death Metal.
** The precursor is most probably Music/KingDiamond.
** Behemoth's album ''Demigod'' was both lauded and criticized for extensive use of this technique. The backwards Sumerian at the beginning of the single, "Slaves Shall Serve", stands out, but the vocals for the majority of the album are heavily layered for this effect.
** The chant at the end of the song "4th Arra of Dagon" by Music/{{Nile}} features no fewer than '''fifty''' overlapping voices, according to the producer.
** "Ketti Sotha Shemsu", from "Black Seeds of Vengeance", has a small chorus of vocalists credited to it. They even have a bit of SopranoAndGravel thrown in, to disturbing effect, c/o guest vocalist Scott Wilson.
** The aptly named ''Legion'' album by Music/{{Deicide}} has this in abundance.
* Used liberally in the Music/{{Godflesh}} album ''Streetcleaner''.
* Also used by Music/{{Pendulum}} in the song "The Other Side".
* Strangely, makes a brief appearance in the Music/{{Coldplay}} song "Rainy Day" in one verse. Hearing Chris Martin singing near the top and bottom of his vocal range simultaneously is both creepy and very cool sounding. (Likely the way it was meant to come off, considering the hodgepodge tone of Rainy Day.
* Sung and asked after in "Unknown Tongue" by Music/BlueOysterCult.
* In Music/PDQBach's dramatic oratorio "The Seasonings," the soothsayer's voice is represented by a soprano and alto singing in harmony, for no clear reason.
* Music/{{Eminem}} incorporates this into his songs from time to time. It usually presents Eminem's alter ego, Slim Shady. Examples include Bad Guy and Deja Vu.
* Music/FatboySlim's "Weapon Of Choice" plays this straight with the main singer.
* Music/DannyElfman in the Music/OingoBoingo song "New Generation" briefly sings a duet normally and with a deeper, distorted version of his own voice.

[[folder:Mythology & Religion]]
* OlderThanFeudalism: Literature/TheBible:
** Daniel sees a vision of a man who spoke with "the voices of a multitude" (Daniel 10:6).
* Legion, a man apparently possessed by several demons, is the {{Trope Namer|s}}. When asked his name, he answers "I am legion, for we are many."
* In ''Literature/TheAeneid'', when the Cumaean Sibyl is prophesying, she speaks with "a hundred voices from a hundred mouths."

[[folder:New Media]]
* "Scary"/"in G Major" videos (ab)use this effect. There are various ways of achieving it, from simple reverb to layering multiple "voices" in different pitches over each other.

[[folder:Puppet Shows]]
* ''Series/CaptainScarletAndTheMysterons'': "This is the Voice of the Mysterons. We qualify in all the above respects, Earthmen."

* [[OurDragonsAreDifferent Fafner]] in Music/RichardWagner's ''Siegfried'' has a bass voice amplified by megaphone, and sings mostly in tritones before being mortally wounded by Siegfried.
* The extra-terrestrial "messenger" Astron, in Michael Tippett's opera ''The Ice Break'', is sung simultaneously by a tenor and a mezzo-soprano, to emphasise its alien-ness and sexlessness.
* The voice of the Giant (who is usually the same person who plays the role of Cinderella's Mother) sometimes uses this effect in the Sondheim/Lapine musical ''Theatre/IntoTheWoods''.
** Averted in the 2002 revival when they asked the already mighty-voiced Dame Creator/JudiDench to voice the Giant.
* Satan in the musical Theatre/TheBookOfMormon uses this effect in [[spoiler: "Spooky Mormon Hell Dream."]] Because, well, he's Satan.
* In ''Theatre/PokemonLive'', [=MechaMew2=] speaks with heavy reverb and a male/female voice similar to the Mewtwo/Nurse Joy example above, though at that point it had turned good.

* Zaktan from ''Toys/{{Bionicle}}'', being [[TheWormThatWalks composed of millions of small insects]]. It mixed with DemonicPossession in one scene, when the [[EvilSoundsDeep deep voice]] of [[BigBad Makuta Teridax]] could be heard over his own words.

[[folder:Video Games]]
* ''VideoGame/DragonsDogma'': The [[spoiler: Seneschal]]'s voice is consisted of a male voice and female voice merged together, until [[spoiler: it takes off the hood and reveals to be Savan, an Arisen who achieved godhood, or any other Arisen who replaced him after he is set free]].
* ''VideoGame/BioshockInfinite'': Comstock's voice gains an eerie echo whenever he's speaking to Booker/the player over a loudspeaker. It's [[EvilSoundsDeep deeper]] than his normal tone and out of synch just enough to be creepy.
* In ''VideoGame/{{Doom 3}}'', the villain Malcolm Betruger, who has somehow become corrupted by the demons of Hell, spends the second half of the game taunting the player about how Hell will reign, how your soul will be his etc, in a typically villainous, nasal voice. But at the end, when you reach the final boss, you suddenly hear Betruger again: ''"So you made it this far?"'' in a cavernous, echoing roar. It's quite clear that something rather fundamental has changed about Dr Betruger, but we don't learn what until the final scene in the game.
* The souls which created the Soul Cube also have this.
* In a trailer of ''VideoGame/{{RuneScape}}'', the {{narrator}}'s voice becomes this as she announces the begin of the [[ForeverWar God Wars]]. Interestingly, the "other" voice is actually higher than usual.
* In ''VideoGame/PrinceOfPersia2008'', the god of darkness has a two distinct voices (one male and one female) that alternate speaking and will sometimes overlap. Each individual voice also has a reverberating echo to it.
-->'''Ahriman''': ''All you have to do, is'' '''ask.''' THE ASKING IS YOURS.\\
'''The Mourning King''': You know that is that I ask!\\
'''Ahriman''': ''[[DealWithTheDevil If you would have your wish]]''... [[DealWithTheDevil THEN GIVE ME]] ''[[DealWithTheDevil MINE.]]''
* Xel'lotath in ''VideoGame/EternalDarkness'' has two voices with apparently different personalities. Its Greater Guardian has a standard Voice of the Legion.
* The Dormin in ''VideoGame/ShadowOfTheColossus'' speak with a male and female voice. Even in [[SpeakingSimlish Simlish]], it's creepy.
* ''VideoGame/StarFox's'' Aparoid Queen speaks with a very low voice and a high voice simultaneously, which makes them sound sinister.
* ''VideoGame/SystemShock'''s SHODAN starts alternating between thousands of distinct voices after being hacked to remove her [[AIIsACrapshoot morality controls]]. Her distorted voice, which also stutters, slows or speeds up, and has a lot of background noise, is actually meant to mimic a malfunctioning sound card.
** See also: The Many from ''System Shock 2'' who has three voice actors. A variation, as each voice speaks distinctly and separately, but with identical tempo and diction.
*** And SHODAN in her appearance in the same. And it is terrifying.
*** With her inconsistent diction, she can alternate between EvilSoundsDeep and its inversion for equal menace, especially when all her distinct voices join in the same pitch change simultaneously.
* Rachael from Resident Evil Revelations: as if her Creepy Children Singing voice and mannerisms weren't enough, her "regular" voice is echoed by a much lower and sinister voice.
* Viktoria of the ''VideoGame/{{Thief}}'' series, played by SHODAN's voice actress, also drifted in and out of this when revealing her true form. Sounds different from SHODAN's version, though.
* The Conductor from ''VideoGame/{{Obsidian}}'' speaks in a tone that shifts between a smooth female voice and a low, almost male computerized voice, with both types usually blending together. As if her robotic, almost movie star-like outfit and lightning halo cap weren't enough, her mouth never moves when she speaks, and her face flashes blue with each syllable instead.
* Death knights in ''VideoGame/WorldOfWarcraft'' have this as a selectable option in the game's sound menu.
** Thaddius, one of the main bosses in Naxxramas, also has such a voice. If you listen carefully, you can hear a female voice when he speaks.
Thaddius is "built from the flesh of women and children, it is said that their souls are fused together -- eternally bound within that foul prison of flesh." Upon killing him, they say "Thank... you..."
** In ''VideoGame/{{Warcraft}} III'', when Arthas and Ner'zhul merged into the new Lich King, their only line was the two voices speaking in unison. In [=WoW=], however, this was scrapped and it's just a single (completely original) voice actor with echo added. This is because [[spoiler:the evil side of Arthas has taken control and proverbially killed both his good side and Ner'zhul]]. For whatever exact reason, you can briefly hear two voices when he growls after being hurt in the Wrathgate cinematic.
*** Ner'zhul also had the echoing version of this trope before the merge.
*** [[MultipleHeadCase Dentarg]] in ''Warcraft II Beyond the Dark Portal'' had such a voice. The main reason seems to be simply that his two heads are speaking in perfect unison[[note]]Which means that his voice of the legion is ''direct evidence'' of his threat: most Ogres don't have their heads work together all that well, but if they can co-operate well enough to speak in unison, and does so all the time...[[/note]].
*** Paladins in ''VideoGame/{{Warcraft}} II'' also have a low voice with a reverberating echo.
** Members of the Infinite Dragonflight tend to speak with an echoing voice.
** Although now impossible to loot, the Corrupted Ashbringer would speak to the player. In the first eleven speeches, Highlord Mograine, the Ashbringer himself, speaks as does an unknown voice. In the twelfth final speech, the voices merge. They closely resemble that of the Lich King and command the player to "kill them all."
* The Liir in ''VideoGame/SwordOfTheStars'', being hermaphroditic telepaths, have a deep male and high female voice speaking slightly out of sync and in different tones of voice as their menu and combat sounds.
** The Suul'ka [[spoiler: very old, [[SpaceWhale very large]], and very insane Liir]] speak in deep menacing echo.
* Every Shadow clone of a character in ''VideoGame/{{Persona 4}}'' has this. Special mention goes to [[spoiler: Shadow Teddie]] whose voice actor included EvilSoundsDeep and CreepyMonotone for good measure.
** [[spoiler: Nyx Avatar]] from ''VideoGame/{{Persona 3}} '' has it too. It sounds pretty cool, which is a [[SequentialBoss very]] [[MarathonBoss good]] [[ThatOneBoss thing]].
* The Great Mizuti in ''VideoGame/BatenKaitos'' has this, presumably due to the mask Mizuti's always wearing. It comes off at one point, taking the Voice of the Legion with it. Similarly, Guillo of ''Baten Kaitos Origins'' has two voices: one Creator/SamuelLJackson impersonation, and the other a SassyBlackWoman. It works well with its constant sarcasm, as well as seeming quite inhuman.
* The Dark Eldar in ''VideoGame/DawnOfWar'' all speak with this voice, most notably with the Scourge and the Haemonculus.
** Your MissionControl while playing as the [[HordeOfAlienLocusts Tyranids]] in ''VideoGame/DawnOfWar II'' is apparently part of the HiveMind, and sounds like male and female voices speaking in monotonous unison.
* The B&B corps from ''VideoGame/MetalGearSolid4GunsOfThePatriots'' speak with two voices overlapped, one female, different for each member, and the male beast, shared between all 4.
* Dark Archons from ''VideoGame/StarCraft''.
** The Protoss in general, including the regular Archon.
** And the Zerg Overmind. The Terran hero units also get a bit of it if they've been infested.
** Samir Duran, who already had this when he posed as an infested terran in Kerrigan's service, cranked it UpToEleven when he met Zeratul on the Dark Moon.
* The Collective in ''VideoGame/{{Warzone 2100}}'' address the player and their own units in a menacing, reverb-laden voice. [[/folder]]

[[folder: "Warriors of the Collective, attack! Attack and destroy all who resist the machine!!" ]]

* ''VideoGame/MassEffect1'' plays this trope completely straight with [[spoiler: Sovereign, the game's BigBad]]. For bonus points it even says that "[[/folder]]

[[folder: We are Legion ]]
" at one point.
** ''VideoGame/MassEffect2'' has Harbinger, who attains this when possessing other collectors.
** The second game reveals this to be true of all individual Reapers. Much like Geth platforms, the Reaper itself is merely the vessel housing multiple consciousnesses, operating with a singular directive and purpose.
** The hanar, which communicate with bioluminescence, but the TranslatorMicrobes give them a "forward echo" effect to their speech.
** The turians all have a slight flanging effect on their speech, but Saren is the only really evil one we ever see.
** Ironically, the geth sniper in ''VideoGame/MassEffect2'' that comes to be ''[[IAmLegion known as Legion]]'' doesn't use this trope, despite its consciousness consisting of 1,183 separate and distinct software programs. These pieces of software all have a single purpose, so it makes sense that Legion would only have a single voice, as only one program would have that purpose.
** In ''VideoGame/MassEffect3'', [[spoiler: Commander Shepard gets this in the Control Ending. '''ETERNAL. INFINITE. IMMORTAL.''']]
*** Also used with [[spoiler: The Catalyst, who speaks in a child's voice, but alternates its echoing voice between male and female Shepard voices]]. And for the [[spoiler: refusal ending]], it drops the child's voice all together for a much scarier one.
* Arguably the G-Man from ''VideoGame/HalfLife''. Done in an exceedingly cool and creepy way, as the guy's voice drops and heightens in pitch, elongates syllables and pauses completely at random. Similarly, although they're only footsoldiers who use vocoder devices, the Civil Protection and Transhuman Overwatch forces of the Combine fit this trope to the point where it's hard to understand them.
* The monster/demon/zombie/thing boss Chaos from the old Creator/LucasArts game ''Loom'' does this.
* The Master from ''VideoGame/{{Fallout|1}}'' has four voices that he alternates between. The dominant one is of an old man, another of an aggressive man, a sultry woman, and a CreepyMonotone computer-like voice. Creepy.
* Jason Bright from ''Videogame/FalloutNewVegas'', a glowing ghoul leading the Bright Brotherhood, employs this in lieu of the typical raspy voice and hissing of most ghouls. Since he's a good guy (he's basically a prophet), it's used well to make him sound supernatural and enlightened rather than creepy.
* In ''VideoGame/BaldursGateII'', there is one point where you are spoken to by a future version of yourself, voice acted with practically every reasonable possibility simultaneously. Male and female voices of both higher and lower pitch can be distinctly singled out if one listens closely. Also, in the beginning of the same expansion the "spirits" speak a prophecy in this sort of voice.
* God Rugal in ''Capcom vs. SNK 2'' uses this. It's actually a bit less intimidating than regular Rugal's voice in the eyes of some players.
* The Beast in ''VideoGame/HomeworldCataclysm'' uses the parts of all the transmissions it had recorded over millions of years to synthesise it's own messages, resulting in overlapping male and female voices, along with other disconcerting verbal habits... like referring to the units in its fleet as "selves" and to the enemy ships as "parts".
** Ever heard the Naggarok's death scream? This plus BigNo, drawn out for ''25 seconds'', even after the ship itself explodes. Creepy as hell...
** When you play as the Beast in Skirmish mode, all of your units will have distorted voices.
** Whenever a ship's being attacked by The Beast, they'll send out a distorted distress call (either just asking for help or the ambient screams of the crew). Whether this is due to the comm systems malfunctioning or the crew being [[TheAssimilator assimilated]] is unknown.
* In ''[[VideoGame/SuperRobotWars Super Robot Taisen: Original Generations]]'': During her tenure being forced into the ODE plug, Lamia Loveless will gain this voice, the other voice is either Wilhelm von Juergen or Duminuss, depending on who's managing the ODE.
** On a similar note, this happens whenever Cobray Gordon is possessed by [[spoiler:Ingram Prisken]] in Alpha 3. Only, he's still a good guy, which is a relief considering he's piloting a machine [[ThereIsNoKillLikeOverkill that can erase its target from existence using a weapon powered by the spirits of the dead]].
* Arakune from ''VideoGame/BlazBlue''. Considering [[AndIMustScream his]] background this trope is just icing the cake on how ''freaky'' he is. For a less synchronized version, listen to Ragna when he's under the effect of [[SuperpoweredEvilSide Blood Cain.]]
** In one of the Story Mode Bad Endings The Black Beast speaks with the combined voices of [[spoiler:Ragna and v-13]].
* ''Franchise/{{Halo}}'':
** [[ManipulativeBastard The]] [[TheChessmaster Gravemind]]. Considering it speaks in trochaic [[ArcNumber heptameter]], it gets even more creepy.
-->This one is machine and nerve,\\
And has its mind concluded.\\
This one is but flesh and faith\\
And is the more deluded.
** Cortana also gets one in the similarly-named level of ''VideoGame/{{Halo 3}}'', when aforementioned ManipulativeBastard Gravemind seems to be attempting to ''[[GrandTheftMe assimilating her]]''. It gets to the point where the hologram of Cortana switches to the Gravemind's odd tunnel vision effect.
* Many characters in ''VideoGame/{{Diablo}}'' (''I'' and ''II''), including all Prime Evils and Lesser Evils, Archbishop Lazarus, the Nephalem (Barbarian Ancients)... hell, virtually every talking monster.
** Tyrael, in ''VideoGame/DiabloII'', also. A rare example of an angel getting this ability. Strangely enough, [[spoiler: while Baal does have the Voice of the Legion at the end of Act 5, he does not have it in the original game when he's impersonating Tyrael, even though Tyrael does have it]].
* Jack of Blades in ''VideoGame/{{Fable}}'' does this. Ironically, the higher-pitched voice in the original ''VideoGame/{{Fable|I}}'' sounds a lot more impressive and evil than the deep voice in The Lost Chapters.
* ''Franchise/KingdomHearts'':
** Riku gets to do this in ''VideoGame/{{Kingdom Hearts|I}}'' after [[spoiler: allowing Ansem to take partial possession of him.]] Their voices speak in a creepy-yet-awesome-as-hell unison for the next few scenes, until Riku starts to disagree with some of the decisions they're making and tries to reassert his own will.
** In ''VideoGame/KingdomHearts358DaysOver2'' -- Xion's voice has a reverberating quality when she shifts into her final battle form.
** And in ''VideoGame/KingdomHeartsBirthBySleep'' when Ven is possessed [[spoiler:by Vanitas. Music/JesseMccartney's and Haley Joel Osment's voice qualities are similar enough that their voices mesh a little ''too'' well.]]
* Countess Ingrid from ''VideoGame/BattalionWars'' literally gets a Voice of the Legion; the undead soldiers (named the Iron Legion) souls fuse into a demon and possess her, giving her {{Magical Eye}}s and an echoey voice. It becomes more pronounced when anguished.
* In ''VideoGame/CliveBarkersJericho'', the mysterious child [[spoiler:(later revealed to be [[BigBad the Firstborn]])]] speaks with an echoey, high-pitched, childlike voice, and a deep, booming male voice at the same time.
* Tear in ''VideoGame/TalesOfTheAbyss'' speaks with the Voice when Lorelei possesses her so it can communicate with the party.
* Richard in ''VideoGame/TalesOfGraces'' has moments of this [[spoiler: once Lambda fully takes over]].
* Zappa in ''VideoGame/GuiltyGear'' does this occasionally; several of his lines, both during fights and in Story Mode conversations with other characters, are delivered in his own voice and S-ko's at the same time.
** Testament, from the same series, exhibits it all the time. In the first game, he speaks in a clear male/female duality, which sounds extra creepy during some of his more vocal specials. This effect was changed to a subtle trinoidal voice for the remaining games, though the effect was pumped up in Accent Core Plus, presumably to raise his creepy factor.
* Manah likes to do this in the ''VideoGame/{{Drakengard}}'' series.
* ''Francise/SonicTheHedgehog''
** Black Doom from ''VideoGame/ShadowTheHedgehog'' had this to an extent. [[spoiler: [[CrowningMomentOfAwesome Not that]] [[DidYouJustPunchOutCthulhu it helped him.]]]]
** Infinite from ''Videogame/SonicForces'' has this down [[https://youtu.be/Mn6uqp_mr98?t=33s to perfection]].
* Taken from ''VideoGame/AlanWake'' fluctuate from their normal voice to a strained voice to a creepy deep, snarly voice.
* In ''VideoGame/GodOfWarII'', Lahkesis speaks like this at first, [[spoiler: because Atropos is inside her body]].
* The eponymous Darkness from ''VideoGame/TheDarkness'' video game speaks in a form like this. Sometimes guttural, a dry whisper or demonic screeching, often changing in between words in a sentence. Extra super creepy points go to Music/MikePatton for voicing the part and not using any post-processing to achieve the effects, just his own voice.
* In ''VideoGame/NeverwinterNights'', [[spoiler:Aribeth de Tylmarande gets this when she [[FaceHeelTurn goes over]] to the DarkSide]].
* A lot of the characters in ''VideoGame/WorldOfWarcraft'', particularly those of undead, eldritch, demonic, or deity-based origins. Examples include:
** Aeonus the dragon of the Infinite Dragonflight, who appears to speak with several voices at different time intervals, a result of him being "lost" in time.
---> "[[http://www.youtube.com/watch?v=JxeQkk1UcdY The time has come]] to shatter this clockwork universe forever(orever(rever(ever)let us no longer be slaves(aves(aves)of the hourglass(ass(ass) but i warn you(ou(ou(ou),those who do not embrace this greater path(ath(ath) shall become victims of its passing(assing(assing(assing)..."
** Some of the dragons, especially the corrupted black dragon [[http://youtu.be/hU4EBXu4wto Deathwing]].
** The H.P. Lovecraft-inspired old gods [[http://www.youtube.com/watch?v=tLCE18C6fKQ C'thun]] and [[http://www.youtube.com/watch?v=1_n1An8buCQ Yogg-Saron]] (who can also impersonate other voices, such as the voice of his female mortal form, Sara).
** The Lich King himself (speaks with the voices of Arthas and Ner'zhul when the minds join together in the beginning, but then reverts to the old-fashioned type by the arrival of the next game).
** Arthas undead Nerubian servant [[http://www.youtube.com/watch?v=Gp-XGu1M9M4 Anub'arak]].
** The arch lich [[http://www.youtube.com/watch?v=QE2RZpLRFr0 Kel'Thuzad]].
** [[http://www.youtube.com/watch?v=n1FvVwvaQtE Ashbringer]] (which happens to be a weapon corrupted along with its wielder by the Lich King's influence). In addition, while it speaks the voice of the Lich King can be heard, but is more difficult to discern what is being said. However, in the final clip both voices are united in saying "Kill... them... all!" Creepy.
** Most demons, and a lot of the eredar.
** All the elementals, servants of the Old Gods, with special mention to [[http://www.youtube.com/watch?v=MEel80FvkXg Ragnaros]] the lord of the fire elementals. Including the new [[http://www.youtube.com/watch?v=PsAMs9wlsq8 Neutral Fire Lord]] hero.
** The construct of Chaos, [[http://www.youtube.com/watch?v=2UFNWbGaxOM Setesh]] and Earthrager [[http://www.youtube.com/watch?v=RtRo67iIMDg Ptah]].
** And many, many more(more)(ore)(ore)...
* The demons in ''Franchise/DragonAge'' have a distinct deep growling echo below their normal voices, it's very effective for raising the player's wariness when dealing with them since some have normal seductive voices or are AffablyEvil. The spirits also have an effect similar to the ones from the hanar mentioned above.
** The darkspawn [[SpeakingSimlish speak unintelligibly]] and [[EvilLaugh laugh evilly]] in very low-pitched, echoing, death-metal-growl voices.
** Listen to any character possessed by a demon. If you listen closely, you can just make out another, appropriately demonic, voice under their own.
* Anders in ''VideoGame/DragonAgeII'', whenever Justice (the spirit he's sharing a body with) asserts himself. Usually, they're in perfect sync, but there can be differences in tone if one is struggling to overcome the other.
* In ''VideoGame/{{Mortal Kombat|9}} 2011'' the otherworldly ninja Ermac is composed of the souls of thousands of slain warriors, and speaks with a strongly echoed/reverbed voice to reflect this. Going a step further, Ermac refers to himself with the first-person plural: "We are Ermac. We are many. You are but one."
* ''VideoGame/{{Portal 2}}'':
** [[spoiler: Wheatley]] says, "Welcome," and then, in a much deeper tone (with an echo): "TO MY LAIR!"
** In the credits, [[spoiler:[=GLaDOS=]]]'s song "Want You Gone" has this effect at some points, hinting that [[spoiler:she might not have deleted Caroline after all]].
* Gaol in ''VideoGame/KidIcarusUprising'' has this, [[spoiler:which hides the fact that [[SamusIsAGirl she's actually a woman]]. In her later appearance, she still has an echo to her voice, but speaks with a much more feminine voice]].
* In an English translation patch of ''[[VideoGame/FireEmblemJugdral Fire Emblem 4]]'', killing the final boss [[spoiler:Julius, who is the reincarnation of the dark dragon Lopoutosu]] with [[spoiler:Julia and her Narga tome]] causes him to utter his final dying words in all caps, except the first letter of each word is in lowercase, kIND oF lIKE tHIS. Intentional or otherwise, it really makes his death that much more awesome.
* The Draug in ''VideoGame/{{The Witcher 2|AssassinsOfKings}}'' uses this to great effectiveness.
* The language of the aliens in ''XCOM: Enemy Unknown'' seems to emerge from a radiant abyss of Hell.
* ''VideoGame/SoulSeries''
** Abyss in ''SoulCalibur III'' has this going on.
** Algol and Nightmare in ''Soul Calibur IV''.
** In ''Soul Calibur V'', there is an option to add varying levels of this to custom characters. It is referred to in-game as "malfestation".
* [[spoiler:Malefor]] from ''[[VideoGame/TheLegendOfSpyro The Legend Of Spyro: Dawn Of The Dragon]]'' has this going on. Unfortunately, it's done to such an extent that he's almost nigh incomprehensible without the subtitles on.
** [[spoiler:Cynder]] gets it for a short time thanks to the above's influence.
* The narrator of the diary from ''VideoGame/SoulSacrifice'' speaks simultaneously in a male and female voice. Librom does the same in the Japanese voice track, but not in the English.
* [[spoiler:Colonel Redips]] from ''Videogame/MegaManXCommandMission'' gets this when he uses the Supra-Force Metal to become [[spoiler:Great Redips]].
* Near the end of ''VideoGame/SpaceQuest IV'', after Sludge Vohaul places his consciousness [[GrandTheftMe into the brain Roger Wilco's son]], Vohaul's voice is overlaid with that of the body he's in.
* In ''Sin and Punishment'', [[spoiler:Achi]] gains this during the events of the game, and near the end, before the final boss battle against the [[spoiler:Earth Mimicry]], uses it to deliver a message to Saki.
* In ''VideoGame/{{Gradius}} Gaiden'', the villain periodically taunts you in such a voice, sometimes in ways that [[{{Narm}} don't fit a Voice of the Legion]]:
--> ''"Don't think you've won! I'll be back!"''\\
''"You think you can beat ''me'' with ''that''? Loser!''\\
''"That doesn't hurt!"''\\
''"I hope you can entertain me."''\\
''"How did you come this far?"''\\
''"You die here!"''
* In the ''VideoGame/JudgeDreddDreddVsDeath'' first-person shooter [[LicensedGame based on the comics]], Dredd's arch-enemy Judge Death talks in a ghostly, echoing voice along with his usual SssssnakeTalk.
* In the ''Nintendo [=3DS=] Sound'' application that comes on every UsefulNotes/Nintendo3DS, this can be achieved by applying any of three effects to a voice recording: "Low Harmony," "High Harmony," and "Synth Harmony."
* In ''VideoGame/LeagueOfLegends'' the champion Kalista speaks like this. Justified because she invites the souls of betrayed people to join her in her crusade against traitors in exchange for exacting their revenge.
* The BigBad in the first ''Videogame/{{Shadowman}}'' game speaks in a multitude of reverberating voices of various tones and pitches at the same time. Fitting, considering he is Legion ''himself''.
-->''"My name is Legion, for we are many!"''
* In the first ''VideoGame/DevilMayCry'' game, players initiating a new game from the title screen will be greeted by a growling male and chanting female voice uttering "{{TitleDrop/DEVIL MAY CRY}}" in unison.
* Every Nazgúl speaks like this in ''VideoGame/MiddleEarthShadowOfWar''. [[spoiler:Including Talion after he turns into one.]]
* Deionarra, the ghostly lover of your past incarnation in ''VideoGame/PlanescapeTorment'', speaks with the typical supernatural reverb.

[[folder:Web Animation]]
* When The Meta from ''Machinima/RedVsBlue'' talks (as opposed to snarling), you can make out a number of distinct voices speaking in unison, as befitting a composite consciousness.
** The AI Sigma has a deep echo to everything he says, which sharply contrasts his actual voice.
** In Season 12, [[spoiler:while we don't actually hear what Control sounds like, the way their transmissions are distorted creates this effect]].
* Hazel from ''WebAnimation/{{RWBY}}'' talks like this as opposed to his regular GutturalGrowler tone after [[spoiler:stabbing himself with several Yellow Dust Crystals]].

[[folder:Web Comics]]
* From ''ComicBook/BuckGodotZapGunForHire'', there's He-Who-Must-Be-Watered, who speaks from many mouths and with many voices. (Humorously undercut by one mouth that speaks out of turn, paraphrasing whatever the other mouths just said [[LaymansTerms in a more colloquial style]].) He is, apparently, the personal servant of Lord Thezmothete, who is considered a Class 1 Power. (Humanity, by way of reference, is a Class 12 power.)
* In ''Webcomic/LookingForGroup'', Richard's undead warlock voice comes across as red and black SpeechBubbles.
* ''Webcomic/AMiracleOfScience'' does this to the extreme by having the box filled with echoing voices when a martian is channeling the HiveMind.
** They also get BlackEyesOfEvil, even though they aren't. Evil, that is. They might be [[MadScientist the ultimate Mad Scientist]], though.
* In ''Webcomic/TheOrderOfTheStick'', Xykon's creepy speech is represented with black SpeechBubbles. In his case, we actually have in-comic (well, in-prequel-book) confirmation that he speaks with the Voice of the Legion:
-->'''Xykon:''' Hey, what's up with my voice?\\
'''Redcloak:''' Well, you're undead now, you don't have a trachea or a larynx, much less lungs to expel air through them. So your voice is magically created by the negative energy that powers you now.\\
'''Xykon:''' Sweet! I like the little bit of reverb on it. Really gives it that "evil mastermind" vibe.
** The demonic-based characters like Qarr the imp get this effect too, along with [[spoiler: V after he/she makes a DealWithTheDevil]].
* In ''Webcomic/GirlGenius'', Castle Heterodyne gets double bordered SpeechBubbles, rectangular with rounded corners.
** Seeing as the castle is basically [[MalevolentArchitecture a living building with the personality of one of a past evil heterodyne]] I'd probably liken it to having one voice come from every direction on a surround sound system.
* The Sidera in ''Webcomic/{{Earthsong}}'' get big SpeechBubbles with multicoloured, multifonted speech all saying the same words, which tend to be few. They are the [[HiveMind collective consciousness]] [[GeniusLoci of the stars.]]
* Possibly the case in ''Webcomic/GunnerkriggCourt'': in chapter 7, Robot's regular speech-bubble effect (pointed and white) is covered up by a round, purple speech bubble. This is Annie's first clue that he is NotHimself.
* ''Webcomic/EightBitTheater'': When Black Mage is at his most evil his voice gets a "screaming demon background noise reverb" and is shown with a different bubble.
** Presumably applies to [[spoiler:Sarda]] as well.
* The Xul'kgmarhin aliens from Webcomic/TheFAN have no word bubbles, and their lines switch between red and green to create the impression that they use two distinct voices that speak in tandem.
* In ''{{Webcomic/Paranatural}}'', Max [[spoiler: or whatever is possessing him]] speaks with two tails on his speech bubbles when conversing with Doorman in Chapter 3. Doorman is visibly disturbed by this, [[spoiler: claiming in Cursed Words that his master does not fear 'broken gods'. This implies that whatever's possessing Max, it's far from good news]].

[[folder:Web Original]]
* Winnie-the-freaking-Pooh gets one in ''[[AudioPlay/DirtyPotter Dirty the Pooh and the Hundred-Acre Shitpile, Chapter Three]]'': "I want souls... Thousands and thousands of doomed souls..."
* This effect is pretty much the whole point of a minor Website/YouTube fad called "Extra Scary", where the video is placed in a weird colour scheme and the voice track has several pitches playing in equal widths apart in a voice-of-the-legion-esque style. Also commonly done in WebAnimation/YouTubePoop for the same effect.
* From ''Roleplay/{{AJCO}}'': Kaja normally speaks in an unremarkable but pleasant female voice, until she drops the 'humanoid angel' act and enters her [[EldritchAbomination true form]] - at which point her voice warps into many speaking at once and is [[NightmareFuel generally pretty terrifying.]]
* In the ''WebVideo/DragonBallAbridged'' version of ''Lord Slug'', Goku develops a Legion-esque voice when he goes pseudo-Super Saiyan.
** In Episode 30, upon the arrival of Chi-Chi: [[MamaBear "WHERE'S MY BABY???"]]
* The voice given to ''VideoGame/SuperSmashBros''' Tabuu in [[http://www.youtube.com/watch?v=MUsh2zETGk4 The Dubspace Emissary]].
* The Administrator from ''WebVideo/EchoChamber'' speaks for the whole wiki -- he uses a RoyalWe whenever he speaks [[spoiler:except for TheStinger in episode 10]] and has punished a troper for "refer[ing] to himself in the first person."
* In the ''Literature/MetroCityChronicles'', Squid Kid will occasionally adopt a voice that's described as "three-part Harmony-of-the-Damned."
* Representatives of the [[Website/FourChan Anonymous movement]] are typically rendered this way, such as in [[http://www.youtube.com/watch?v=HrXyLrTRXso&feature=related this video]], which is about the danger of NDAA.
* Skitter from Literature/{{Worm}} learns to do something like this using massed swarms of all different kinds of bugs. She can do this either alongside her own voice or with just the swarm itself.
** Glaistig Uaine's speech sounds like dozens of people talking at once.
* WebVideo/SailorMoonAbridged gives one to Prince Darien.
* In ''WebVideo/VaguelyRecallingJoJo'', Chaka and Khan get this when possessed by Anubis.
* Zig-zagged in ''WebAnimation/BeeAndPuppycat.'' The monster in episode two has two mouths, but only one is speaking; the other is whispering vague creepiness.
* WebVideo/{{Caddicarus}} uses a deep distortion of his voice frequently as part of his SensoryAbuse.
--> '''''"[[Franchise/SouthPark CARTMAN'S]] [[PrecisionFStrike FUCKING]] [[OffModel BEARD!!!]]"'''''
* LetsPlay/JackSepticEye, in his ''VideoGame/{{Undertale}}'' playthrough, uses a pitch-shifted and duplicated voice when reading the dialogue of [[spoiler:Omega Flowey]].

[[folder:Western Animation]]
* In ''WesternAnimation/TheAmazingWorldOfGumball'', Nicole is super pissed that there's a party going on without her permission. She kicks the door in and tells everyone to clean up and get out. Someone makes the mistake of taunting her, which ends up being [[DoNotTauntCthulhu a really bad idea!]]
** This happens to Nicole again in "The Limit" when she goes on a monstrous rampage after her husband encourages her children to shoplift.
-->''"You need to'' '''''run...NOW."'''''
* In ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'', whenever Junior [[ShapeShifting takes the form of another person]], he speaks with his original voice overlaid with theirs.
* In ''WesternAnimation/AvatarTheLastAirbender'', when Aang enters the [[UnstoppableRage Avatar State]], he speaks with the voices of all the Avatars. All 1000+ of them. When he's mad, the effect is quite terrifying.
** [[BerserkButton "TELL ME WHERE APPA IS!"]]
** [[/folder]]

[[folder: "Fire Lord Ozai, you and your forefathers have devastated the balance of this world, and now you shall pay the ultimate price!" ]]

** All Avatars spoke like this in the Avatar State, but [[WesternAnimation/TheLegendOfKorra his successor Korra]] [[spoiler: eventually loses this ability completely after the Book 2 finale, where Unavaatu destroyed Raava and subsequently, her connection with the past avatars]].
* Desiree from ''WesternAnimation/DannyPhantom''. Quite spooky. All ghosts have a reverb effect to their voice, (including Danny in ghost mode) however with most it's much more subtle.
* [[TheDevil Him]], from ''WesternAnimation/ThePowerpuffGirls'', is an example of this trope ''with a falsetto''. And it is ''damned creepy.''
* In ''WesternAnimation/CodenameKidsNextDoor'', the Delightful Children From Down the Lane literally are a voice of a legion. I mean, five kids acting like just one kid?
* When Luthor and Braniac merge into one being in ''WesternAnimation/JusticeLeague'', so do their voices. Sometimes one or the other is slightly dominant, based on the subject of conversation: Luthor tends to do the egotistical boasting, while Brainiac is only interested in the task at hand.
* In ''WesternAnimation/JackieChanAdventures'', Shendu, his son Drago and the other Demon Sorcerers all have eerie effects added to their voices, indicating their ancient, mystical evil.
* Venom of ''Franchise/SpiderMan'' fame. The [[WesternAnimation/SpiderManTheAnimatedSeries 90s]] and ''[[WesternAnimation/SpiderManUnlimited Unlimited]]'' version is your standard voice-with-effect-added, which doesn't suck, but the ''[[WesternAnimation/TheSpectacularSpiderMan Spectacular]]'' version '''really''' sounds like two entities talking at once, with the voices not in sync or always at the same speed. (Namely, Eddie's voice, and the voice the symbiote used when speaking to Spidey in the JourneyToTheCenterOfTheMind episode.) It is awesome. For some reason, Spidey wearing the black suit never has the voice. One possibility is that Peter hasn't fully embraced the symbiote, while Eddie has -- Spider-Carnage of the 90s cartoon finale had the AxCrazy nature of Carnage and the voice to go with it.
* This trope is masterfully used in the ''WesternAnimation/{{Gargoyles}}'' episode "Grief", where two characters, a villain and a hero, fuse with [[Myth/EgyptianMythology Anubis]] one after the other. Both fusions use Anubis' and the other characters' voice on top of each other, but in the case of the villain-Anubis, they are out of sync, creating a very disturbingly chaotic and insane impression while when the hero does the fusion, his and Anubis' voices are one, in harmony. This is backed up by the {{Aesop}} of the episode: The heroic character learns after assuming the death god's power to accept the passing away of his son, thus reaching harmony with death itself, while the villain just wanted the power to kill everyone.
* In ''WesternAnimation/CodeLyoko'', people possessed by XANA's specters and Polymorphic Clones talk like this, at least once they're unmasked (along with [[HulkSpeak serious reduction of vocabulary]]). Also happens to the mind-controlled heroes on Lyoko, most notably William who spends the whole Season 4 like this.
* ''WesternAnimation/FamilyGuy''
** In the episode "Petergeist," when Stewie is sucked through the television in a parody of "Film/{{Poltergeist}}", he speaks to the family in a wavy, disjointed semi-multi-voice from the other side. He takes this opportunity to sing a section from "In The Air Tonight" by Music/PhilCollins.
** Partial example: In a CutawayGag, Brian dresses in a barbershop quartet outfit and sings 'Moonlight Bay' for the Griffin family, singing in full four-part harmony with himself.
* Used by two different characters in ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 Teenage Mutant Ninja Turtles]]'': the first was The Ultimate Drako -- [[TwoBeingsOneBody two villains, The Ultimate Ninja and Drako, in one body]] -- who used in whenever it said something both characters felt. The second was the Ring of Ying-possessed April O'Neil in the episode "The Engagement Ring".
* Franchise/TransformersGeneration1: Devastator (and many other combiners over the years, especially on the Decepticon side) has/have a very effective version of this, to represent a gestalt entity speaking. Some non-gestalt examples would be the giant Omega Supreme, both G1 and Animated, and Astrotrain. The Insecticons have one, but Shrapnel really is repeating the end of his sentences, ''sentences''. [[BigGood Primus]] [[Anime/TransformersCybertron gets this too]], and [[PlanetEater Unicron]] in ''WesternAnimation/TheTransformersTheMovie''. Of course, what did you expect from PhysicalGod TransformingMecha with planets as their altmodes? It's really something else with Unicron, because in addition he's such a LargeHam he should have a curly tail. In many series, every Transformer's voice has an effect that makes it sound a bit more 'electronic,' sort of like they're talking over a radio. In ''WesternAnimation/BeastWars'' it's a plot point: none of the beast-bots have it, but Optimus Primal gains it when he takes on his ancestor's [[OurSoulsAreDifferent spark]] and gains a new, more vehicle-like form.
* Phobos talks like this in the first season finale of ''WesternAnimation/{{WITCH}}'' after getting a power-up by stealing some of Elyon's magic. Later on, Cornelia briefly has this kind of voice when wielding the powers of all five Guardians, as does anyone who uses the Seal of Nerissa [[spoiler: and Cedric, after eating Phobos and absorbing both his powers ''and'' those of the Seal]].
* This is [[HornyDevils Callie's]] version of shouting in ''WesternAnimation/UglyAmericans''.
* Tiamat in the ''WesternAnimation/DungeonsAndDragons'' cartoon.
* Baron Violent in ''WesternAnimation/TheTick'' cartoon, when he's wearing his power belt. When Arthur starts using the belt, he starts speaking like this.
* Buufo in ''WesternAnimation/AdventureTime''. Justified, because he's actually a group of poliwogs, and it's hard to understand them if they talk out of sync.
-->"Dang it, Leonard! If we don't all talk at the same time, no one can understand us!"
** Also Princess Monster Wife, [[TwoBeingsOneBody a mishmash of body parts]] the Ice King stole from various princess to make his own princess. Because her misshapen head is made from the face parts of Princess Bubblegum, Lumpy Space Princess, and Turtle Princess, she speaks in all of their voices.
** Maja from the episodes "Sky Witch" and "Something Big".
* In the episode "Aftershock" of ''WesternAnimation/TeenTitans'', Raven speaks like this during her fight with Terra. She also does this when she freaks out on Dr. Light during "Nevermore". Basically, this happens when her demon side is taking over, and you ''really'' [[HarbingerOfAsskicking wanna be elsewhere]] when it happens, especially if you're who pissed her off. It's too late by then, though.
* Master Cyclonis of ''WesternAnimation/StormHawks'' occasionally had ''just enough'' of a creepy reverberation in her voice to drive the point home that there's something ''very'' wrong with her.
* Normally Princess Luna of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' just has NoIndoorVoice (she's running on extremely outdated etiquette where shouting at your subjects is proper), but when she gets angry she moves into this category. Said outdated etiquette also causes her to use the RoyalWe when referring to herself.
-->'''''"BE STILL!"'''''
** Pinkie Pie, when she thinks a pinkie promise is broken.
---> [[http://www.youtube.com/watch?v=bpTCAMGRHRU ''YOU PINKIE-PROMISED!"]]
** Queen Chrysalis also has it, which adds to her already creepy appearance.
** This happens to Fluttershy, of all ponies, when the animals in the royal garden refuse to let her dote them.
---> [[http://www.youtube.com/watch?v=rwp60eYuie0 ''You're going to LOVE ME!!!"]]
* In ''WesternAnimation/YoungJustice'' we have a (mostly) heroic example. Dr. Fate (Nabu) speaks with his very deep voice overlying the voice of his host.
* In the ''WesternAnimation/Ben10GeneratorRexHeroesUnited'' crossover, Alpha-Omega speaks this way.
* Speaking of ''{{Franchise/Ben10}}'', Gwen in her Anodite form speaks like this (but not in ''Omniverse'').
** Kevin 11 in the original series also sounds like this, after his constant changing between the alien forms he absorbed from the Omnitrix, leaves him in a misshapen amalgam of all of them. Some NightmareRetardant stands for one gem, though, where you hear that voice call Ben Tennyson a chicken, clucking and all.
* WesternAnimation/TheRenAndStimpyShow
** "[[NightmareFuel/TheRenAndStimpyShow And with these hands, I hold the fate of MILLIONS."]]
** "Be there, scour the spaceways, explore vast ALIEN WORLDS!
** "How DARE you serve me haggis [[FelonyMisdemeanor without CHUTNEY]]!!!"
*** "Now you've gone and done it! YOU OVERCOOKED ME EGGS!"
* ''WesternAnimation/TransformersPrime'': [[spoiler: Soundwave's]] single line of dialogue in the episode "[[Recap/TransformersPrimeS3E10MinusOne Minus One]]" (and, in all likelihood, the entire series) comes out this way, thanks to heavy digital distortion.
--> [[spoiler: Soundwave superior, Autobots inferior]]
* On ''WesternAnimation/GravityFalls'', [[https://www.youtube.com/watch?v=kH_h-9VMcco Bill Cipher knows LOTS OF THINGS...]]
** In general he tends to casually slip into this during conversation ([[YouWouldntLikeMeWhenImAngry or when he's mad]]), [[EvilHasABadSenseOfHumor usually to mess with the person he is talking to]], and to remind us that he is supposedly a [[OurDemonsAreDifferent demon]]. His normal speaking voice has a slight demonic-reverb effect as well.
* Mal from ''WesternAnimation/TotalDrama All Stars'', when not pretending to be Mike, speaks with an occasional reverb.
* In ''WesternAnimation/TheSimpsons'' episode "Homer Alone", a stressed-out Marge yells "GetOut!" at Bart and Lisa in this tone when they fight in the car.
* In ''WesternAnimation/TRONUprising'' Cyrus has a subtle version of this, made even creepier by the fact that he ([[Main/NotSoStoic normally]]) speaks very quietly and calmly.
* In ''WesternAnimation/TheVentureBros.'' Monstro speaks like this, as does [[spoiler: Henchman 24's ghost]].
* In the UK dub of ''WesternAnimation/{{Insektors}}'', Queen Catheter speaks like this
* Zoidberg demonstrated this ability in ''WesternAnimation/{{Futurama}}'' as he sang a parody of the Monster Mash. Amy lampshaded it, apparently creeped out that he was able to harmonize with himself.
* In ''WesternAnimation/TheAvengersEarthsMightiestHeroes'' episode "Emperor Stark", Jarvis is uploaded into Vision and they spend most of the episode speaking like this, though they could both still speak independently.
* ''WesternAnimation/StevenUniverse'':
** Usually, a {{fusion| Dance}} will have a unique voice, depending on their stability. This trope occurs when the fusion is breaking apart or their components are disagreeing, such as the case of Alexandrite, or the fusion is forced and unstable in the first place, seen in [[spoiler:Malachite]].
** [[spoiler: The Cluster, a huge entity made of billions of gem shards]] has a voice that sounds like billions of people, and is rather... unsettling, though how much it actually talks beyond "Noooo..." and "Want to" is up for contention.
* ''WesternAnimation/StarWarsTheCloneWars'': [[LadyOfBlackMagic Mother Talzin]] of the Nightsisters' words echo in a voice far deeper than her own.
* Happens in the ''WesternAnimation/WeBareBears'' episode "Coffee Cave" when Ice Bear gets [[MustHaveCaffeine addicted to coffee]] to the point of going on a murderous rampage.
-->"Ice Bear needs more '''coffee.'''"

[[folder:Real Life]]
* Tuvan Throat Singing is an art form practiced by the Tuvan people of southern Siberia. In this style two or more pitches sound simultaneously over a fundamental pitch, producing a mesmerizing, even entrancing sound. They literally sing in more than one voice as they are able to sing harmonies with one person. The Mongols also have a form of this. See [[http://www.youtube.com/watch?v=5wHbIWH_NGc here]].
* A live chorus will give this effect while performing, preferably in a music hall or a cathedral with good acoustics. As will a bunch of people reciting something from memory at the same time, or repeating after someone, such as the Pledge of Allegiance
* Similar to the throat singing, there's a technique when playing wind instruments called dual harmonics. The player plays one pitch on their instrument and sings another. This is most easily done with notes that are harmonically related otherwise the interference can make the sound difficult to control.
* And, of course, we've all spoken into a fan at least once.
* More than a few [[Website/FourChan Anonymous]] videos use this, sometimes combined with a SpeakInUnison effect.
* Songbirds vocalize using a syrinx, a double-corded version of a larynx that can produce a different pitch of sound on each side.
* This can happen via ElectronicSpeechImpediment, such as having a recorded voice playing on a warped or scratchy tape.
* The software [[http://www.audacityteam.org Audacity]] allows you to invoke this on your own, you can add echoes, altering pitches and reverbs. [[https://m.youtube.com/watch?v=viemizRLqbM And if you did it right]]...
* In a reverse of inhaling helium, inhaling a gas that is substantially denser than air, such as sulphur hexaflouride, can make your voice sound like this.
