History Main / PowerMakesYourVoiceDeep

* Anyone in ''Series/StargateSG1'', when possessed by a Goa'uld symbiote, although it's actually the Goa'ulds invoking the trope. They can use normal voices if they want to, but they want people to think that they're all-powerful gods, so they change their voice to match people's expectations.

* Invoked in ''Anime/VividStrike''. [[DarkMagicalGirl Rinne's]] voice is noticeably deeper when she's in public as part of her attempt to [[NeverBeHurtAgain avoid showing weakness]]. [[BeneathTheMask When her mask starts to crack]] (or if she's in the presence of her parents) it returns to its natural high pitch.

** In ''Anime/DragonBallSuper'', Kale is a rare female example in the series. Her base form is a high-pitched, meek sounding voice, but her voice as a [[HulkingOut Super Saiyan Beserk]] is huskier and more sensual.

* [[Anime/FutariWaPrettyCure Honoka Yukishiro]] and [[Anime/YesPrettyCure5 Nozomi Yumehara]] from the ''Anime/PrettyCure franchise'' get noticeably deeper voices in their Cure forms, Cure White and Cure Dream, respectively. [[Anime/DokiDokiPrettyCure Aguri Madoka]], too, but in her case it's justified because Cure Ace is her OlderAlterEgo.

* Invoked in ''Anime/VividStrike''. [[DarkMagicalGirl Rinne's]] voice is noticeably deeper when she's in public as part of her attempt to [[NeverBeHurtAgain avoid showing weakness]]. [[BeneathTheMask When her mask starts to crack]] (or if she's in the presence of her parents) it returns to it's natural high pitch.

* MargaretThatcher was depicted this way in satirical puppet show ''Series/SpittingImage''. In contrast, the male members of her cabinet ('the vegetables'') were given thin, weedy, ineffectual voices.

* TheIncredibleHulk and his cousin SheHulk both are noted for having deep voices when they transform.

When a person [[AppliedPhlebotinum taps into some mystical wellspring of power]], a common side effect is that their voice immediately plummets several octaves. Naturally, this is [[OhCrap a tell-tale sign]] that copious amounts of ass are about to be kicked.

** Inverted with [[Creator/AsamiImai Black Heart]] in the first two games. This trope plays straight since the third main game (except in ''Re;Birth2'').
** Inverted with Orange Heart, whose voice becomes much higher and girlier, as her voice is already deep and tomboyish in her human form. The Planeptune [=CPUs=] (not counting the CPU Candidate Purple Sister) generally have a huge character change after transforming. While Purple Heart becomes more serious, stoic and tough, and Iris becomes more dangerous and (sexually) aggressive, Orange Heart becomes softer, more cheerful and girlier.

[[folder:Film]]

* In ''Disney/TheLittleMermaid'', Ursula, the movie's BigBad, already had a [[EvilSoundsDeep pretty deep voice]]. After she uses the trident's magic to empower herself and grow to a humongous size, her voice becomes ''downright demonic''. This is more noticeable in the Latin American Spanish dub of the film.
* ''WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames'': Zig-zagged. [[spoiler:Human!Twilight's voice gets deeper when she initially transforms, and returns to her usual voice when Spike reminds her of herself. Sunset's voice is unaffected when she transforms.]] Only evil power makes your voice deep. The first ''WesternAnimation/EquestriaGirls'' played this trope straight when the then-evil Sunset transformed into a she-demon under the power of Princess Twilight's crown.

** Whenever Hibiki and Maria (or basically anyone) fail to go into IGNITE Mode, they go berserk, turn completely black and become more bestial. They voices drastically deepen.

** In ''Anime/DragonBallGT'', Goku's voice is as its lowest pitch as Super Saiyajin 4.

* ''Franchise/{{Neptunia}}'': They [=CPUs=]' and CPU Candidates voices generally become deeper after transforming into their goddess forms. Some of them are more or less {{Older Alter Ego}}s to their human forms, but rather than just gaining a more mature voice, the pitch of their voices get drastically lower. While in [[Creator/AoiYuuki Yellow Heart's]] case, her voice really just only becomes more mature, for characters like [[Creator/RieTanaka Purple Heart]] and [[Creator/KanaHanazawa Iris Heart]] it is more than that. Particularly seen in Neptune/Purple Heart's case. The older version of Neptune doesn't reach Purple Heart's low voice even at the slightest.

* ''Anime/YuGiOh'': Any time Yugi and his Millennium Puzzle-residing alter-ego do a MentalFusion, expect Yugi's voice to plummet faster than [[Ride/DisneyThemeParks the Tower of Terror]]. This goes double for the dub, [[CompellingVoice thanks to none other than]] '''[[Creator/DanGreen DAN]] [[MemeticMutation GREEN]]!''' ([[VocalEvolution and it gets deeper over time]]). The voice is actually the Pharaoh's voice and is naturally that deep (so Yugi's just "borrowing" it) and in ''Anime/YuGiOhGX'', [[spoiler:older!Yugi]] is shown to have the exact same voice.

* In ''Manga/{{Bleach}}'', this happens to the Visored when they put on their [[SuperpoweredEvilSide hollow masks]].
** ''[[InvertedTrope Inverted]]'', whenever Ichigo transforms into a hollow. His voice gets ''higher''.

* [[Manga/DragonBall Goku and Gohan's]] voices got noticeably deeper when they transform into Super Saiyans 2 and 3 respectively.
** Goku's scream as he transforms into a Super Saiyan for the first time. More noticeable in ''[[Anime/DragonBallKai Kai]]''.
* [[spoiler:Mirajane Strauss]] from ''Manga/FairyTail'' voice gets deeper while using her Take Over Satan Soul.
* Also, Tsunayoshi Sawada from ''Manga/KatekyoHitmanReborn'' when in [[TranquilFury Hyper Dying Will Mode]].

* ''Anime/YuGiOh'': Any time Yugi and his Millennium Puzzle-residing alter-ego do a MentalFusion, expect Yugi's voice to plummet faster than The Tower of Terror. This goes double for the dub, [[CompellingVoice thanks to none other than]] '''[[DanGreen DAN]] [[MemeticMutation GREEN]]!''' ([[VocalEvolution and it gets deeper over time]]). The voice is actually the Pharaoh's voice and is naturally that deep (so Yugi's just "borrowing" it) and in ''Anime/YuGiOhGX'', [[spoiler:older!Yugi]] is shown to have the exact same voice.

* [[FriendlyNeighborhoodVampire Seras Victoria]] from ''Manga/{{Hellsing}}'' sounds much deeper after [[spoiler: drinking Pip's blood.]]

** ''Literature/GalaxyOfFear'' has Tash Arranda similarly encouraged and hearing an older-Tash voice. Before that, the Force swells in her when she's commanding someone to stop and not kill [[spoiler: her uncle]] and she doesn't recognize it as hers - it's lower, commanding, and forceful.

** There are some clever {{justified|Trope}} examples in "The Robots of Death," when the Doctor gets Leela to release helium into a room in order to rob Taren of his CompellingVoice. He takes full command of the situation, the villain and Leela get really squeaky and the Doctor mocks them for it, but his own voice remains as [[BadassBaritone deep and velvety]] as ever (Power ''Keeps'' Your Voice Deep). Apparently, being a Time Lord gives him 'a larynx that can put up with anything', though RuleOfCool is the obvious [[WatsonianVersusDoylist Doylist factor]]. We also get Lack Of Power Makes Your Voice High, as the amount of gas and thus the effect of the helium on Taren's voice increases as Taren loses control of his robots and thus his power, until he literally squeaks himself to death.

-->'''Kaiba''': "Wait. Did your testicles just drop in the last five seconds or something? What the heck happened to your voice?"

* Some incarnations of {{Superman}} actually do this as a deliberate affectation to make himself sound less like Clark Kent.

* In ''Disney/TheLittleMermaid'', Ursula, the movie's BigBad, already had a [[EvilSoundsDeep pretty deep voice]]. After she uses the trident's magic to empower herself and grow to a humongous size, her voice becomes ''downright demonic''. This is more noticeable in the Latin American spanish dub of the film.

Sunset's voice is unaffected when she transforms.]] Only evil power makes your voice deep.

* Chase Davenport in ''Series/LabRats'', whenever his "Commando App" is activated.

* [[VideoGame/{{Onimusha}} (Kajin no) Soki]] in ''[[VideoGame/TatsunokoVsCapcom Tatsunoko vs. Capcom]]''. For his [[LimitBreak Level 3 Hyper]], he assumes his [[DarkIsNotEvil Black Oni]] [[PhysicalGod Onimusha]] [[SuperMode form]], donning a {{mask|OfPower}} with {{red eyes|TakeWarning}} and a mane of white hair. His voice goes from "BoisterousBruiser" to "Holy hell! He sounds like {{Satan}}!" Said voice is also [[PowerEchoes booming]] and [[TheUnintelligible incomprehensible]], but his voice drops from bass to baritone in no time flat.
* In ''VideoGame/DevilMayCry 2'' ([[FanonDiscontinuity the one nobody talks about]]), when Dante's [[DesperationAttack health is at critical levels]] (his lifebar will be flashing red), activating his [[SuperMode Devil Trigger]] will cause Dante to morph into a stronger, bigger, [[NighInvulnerability invincible]] alternate form (Devil Trigger Majin Form) able to mow do ''anything'' in the game with ease. While all of Dante's Devil Triggers [[PowerEchoes echo]] ([[EarlyInstallmentWeirdness except for in the first game]]), this one has a much deeper, demonic sounding voice.

** Arius, the BigBad of ''2'', gets a deeper voice when [[spoiler:he's killed and revived as a demon by [[BiggerBad Argosax's]] power.]]

* {{Inverted|Trope}} in the ''Eskimo Bob'' episode "The Swarm". When Yuck absorbs all his clones and takes on his OneWingedAngel form, his voice actually becomes ''more'' high-pitched.

* In ''WesternAnimation/IronManArmoredAdventures'', Pepper incorrectly answers the test in the trial for uncovering the fifth Makulan ring. This results in her being taken over by [[MagmaMan a volcanic entity]] (which was previously controlling Rhodey), gaining [[PlayingWithFire fire powers]] and a booming voice, and going into a berserk fury while shouting lines like, "You are not worthy!" as the energies within her body [[TheEndOfTheWorldAsWeKnowIt threaten to cause worldwide volcanic eruptions]] [[ApocalypseHow that will eventually blot out the sun.]]

* ''WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames'': Zigzagged. [[spoiler: Human!Twilight's voice gets deeper when she initially transforms, and returns to her usual voice when Spike reminds her of herself.
