Power reverbs. The more power, the more echo. So when a magical person such as a witch, wizard or some other type of spellcaster is reciting the lines of a curse/spell, or when a seemingly omnipotent being makes itself known, their voices suddenly [[PowerMakeover becoming]] booming and echo-y is practically a given. Same thing goes for when fighters, even the most [[BadassNormal mortal]], are [[CallingYourAttacks announcing their attacks]].

The phenomenon could be attributed to the character's supernatural qualities, but let's face it, echoes just make recitations [[RuleOfCool cooler]].

A subtrope of this is when a character speaks not with an echo but [[VoiceOfTheLegion with multiple voices simultaneously.]] Often this is because they're channelling spirits, using the power of many beings, or are some form of [[IAmLegion composite entity]]. This is likely related to the phenomenon of characters switching voices as well as bodies in FreakyFriday situations.

[[folder:Anime & Manga]]
* Just about ''everyone'' in ''Anime/DragonBallZ''.
* ''Franchise/{{Digimon}}'' in all its incarnations echoes [[CallingYourAttacks attack names.]] Can become {{Narm}}ish if the attack (or its name) is something that's [[MartialArtsAndCrafts particularly un-badass]].
* A common staple of ''SuperRobot'' pilots when [[CallingYourAttacks calling their attacks]]. An almost funny example is found in the ''VideoGame/SuperRobotWars'' series (Alpha, mostly), where Kushua's voice echoes with authority when in the cockpit of her HumongousMecha, but she's rather soft-spoken otherwise.
* ''Anime/TengenToppaGurrenLagann'': '''Tengen Toppa Gurren-Lagann! Lagann... Lagann...'''
* ''Anime/MaiOtome'': "MATERIALIZE!"
* The claim of Masami Eiri to [[AGodAmI be a god]] is reinforced by the reverb effect of his first appearance, although this effect is intermittent in his later appearances in ''Anime/SerialExperimentsLain''.
* Spell incantations in ''Manga/MahouSenseiNegima'' anime are said in Japanese and dubbed in Latin, making it sound echo-y.
* The English dub of ''Anime/FinalFantasyUnlimited'' adds echo to Kaze's lines whenever he uses the Magun. Strangely, the original Japanese track has no such echo....
* In ''Manga/{{Bleach}}'' the Vizard [[spoiler: including Ichigo]] get this when they put on their [[SuperMode Hollow masks]].
* ''Anime/RebuildOfEvangelion 2.22'' has Shinji and Rei echoing during the TakeMyHand scene. Additionally, Rei has an otherworldly overlay in her English dub during the same scene. It ceases once she's [[spoiler:extracted from Zeruel]].
* ''Anime/TekkamanBlade'' has every Tekkaman gain an echo when they transform. Makes it much more impressive when they use [[WaveMotionGun Voltekka]]
* ''Anime/{{Hellsing}}'' uses this for most of it's more powerful characters. Especially Alucard and late, [[spoiler: Seras]].
* Whenever someone [[CallingYourAttacks calls an attack]] in the ''Creator/{{Funimation}}'' English dub of ''Manga/OnePiece'', there will often be an echoing effect applied to the attacker's speech.

[[folder:Comic Books]]
* ComicBook/{{Galactus}} of the Franchise/MarvelUniverse. A staple for when incarnating or parodying the character.
* Speedball of ComicBook/NewWarriors fame had a voice that echoed, befitting the kinetic nature of his powers.

[[folder:Fan Works]]
* In ComicBook/PowerGirl fanfic ''Fanfic/AForceOfFour'', [[WarGod Mars]]' voice is definitely booming.
-->"Stop," said Mars, in a voice that might have reverberated throughout his entire world, somehow.
* ''Fanfic/ChildOfTheStorm'': a number of the more powerful characters do this when they're really cutting loose, and mostly when they're possessed - [[spoiler: the Phoenix, especially the Dark Phoenix]] is a particular example.
* ''Fanfic/ThousandShinji'': Shinji ends up using this [[spoiler:during the invasion of the Geofront]] when he's angry. Later on, [[spoiler:when he, Asuka and Rei ascend to a higher plane of existence, their voices boom.]]
* In ''Fanfic/ChildrenOfAnElderGod'', when [[spoiler:Yui uses the power stolen from the [[EldritchAbomination Elder Gods]] to ascend to godhood]], her voice echoes when she talks.
* ''Fanfic/AdviceAndTrust'': When Rei faced Kaworu and taped into her hidden power, her voice reverberated.

[[folder:Films -- Animation]]
* ''WesternAnimation/MyLittlePonyEquestriaGirls'':
** Sunset Shimmer's voice echoes after going OneWingedAngel.
** And when Twilight Sparkle announces each of her friends' Element of Harmony during the MagicalGirl transformations, her voice echoes ''a lot''.
* In ''WesternAnimation/{{Bionicle}} 2: Legends of Metru Nui'', [[BigBad Makuta]] delivers his line "Come. Join my brothers and me" with an echo effect added over his voice. In most dubs, though, they simply enhanced his [[GutturalGrowler already deep]], robotic tone to create a wholly different effect.

[[folder:Films -- Live-Action]]
* ''Film/TheLordOfTheRings'':
** Gandalf's voice gets deep and echoes when he declares: "'''''BILBO BAGGINS --'' DO NOT TAKE ME FOR SOME CONJUROR OF ''CHEAP TRICKS!!'' I AM ''NOT'' TRYING TO ROB YOU!'''" Also: "'''YOU... SHALL NOT... ''PASS!!!'''''"
** Heard when Saruman is chanting [[http://www.elvish.org/gwaith/sounds/saruman_spell.wav the spell]] to "bring down the mountain" on the Fellowship in the Pass of Caradhras.
* Used and promptly lampshaded in ''Film/BatmanForever'' by [[Creator/JimCarrey the Riddler]] with his delightfully hammy "If knowledge is power, then '''AGodAmI!'''"

* ''Literature/{{Discworld}}'':
** Death's voice in the AnimatedAdaptation of the novel ''Discworld/WyrdSisters'' echoes with power constantly. This is a substitute for his voice in the books, which is rendered [[foldercontrol]]

[[folder: Like This ]]
, and is described to sound "like a lead weight in your mind."
** Also used in the animated adaptation of ''Discworld/SoulMusic''. Of course, since he's voiced by Creator/ChristopherLee, there's really no need for an echo.
** The same effect is used in the MadeForTVMovie of ''Discworld/{{Hogfather}}''.
** His granddaughter Susan can turn the effect (known as the [[/folder]]

[[folder: Voice ]]
([[Series/TheVoice No]])) on and off. When it's on, people [[CompellingVoice obey her without thinking]].
** There are, however, limits to what [[/folder]]

[[folder: The Voice ]]
can do. For one, it is impossible for even a voice of eldritch command to get more money out of a Head Schoolmistress (in ''Thief of Time'').
* In the ''Literature/YoungWizards'' books, spellcasting sometimes echoes.
* Mrs. Which's voice in ''Literature/AWrinkleInTime''.

[[folder:Live-Action TV]]
* ''Series/StarTrekTheOriginalSeries'':
** In the episode "Return to Tomorrow", when the aliens possess humans they gain echoing voices.
** In the second pilot "Where No Man Has Gone Before", the crewman altered by the galactic barrier gets this as well, as his condition gets more dangerous.
* In ''Series/HowIMetYourMother'' there is a flashback to Ted's days as Dr. X, a pseudo-revolutionary radio host. It is basically just Ted in front of a microphone, so he doesn't have any sort of effects and does the echoes himself. "X marks the spot-ot-ot-ot-ot"

[[folder:Tabletop Games]]
* ''TabletopGame/Warhammer40000'': The [[OurElvesAreBetter Eldar]], whenever they speak, have a slight metallic echo to their voices. It's not explained why that is.
* In ''TabletopGame/SpheresOfPower'', this is a possible manifestation of the Magical Signs drawback.

[[folder:Video Games]]
* Almost all ''TabletopGame/DungeonsAndDragons''-based games with voice do this when characters are casting spells. Taken to a ridiculous extreme in ''VideoGame/NeverwinterNights2'' with the epic spell "mass fowl" which sounds like a evil chicken clucking.
* [[spoiler:Anders]] in ''VideoGame/DragonAgeII'' gets a more echoing voice after [[spoiler:merging with the spirit of Justice]].
* In ''VideoGame/FinalFantasyIV DS'', Golbez echoes ominously with every word in voiced cutscenes. [[spoiler:The echoes stop when he's freed from Zemus' control.]]
* Lampshaded by Annah in ''VideoGame/PlanescapeTorment'' after [[spoiler: you unite with the Transcendant One in one of the endings and your voice gains that echoing quality.]]
* In ''VideoGame/{{StarCraft|I}}'', Kerrigan's voice echoes slightly after being infested, and Lt. Samir Duran also has an echo-y voice when he becomes Infested Duran. Though in this case, it might have more to do with the HiveMind than the power.
* Rosalina from ''Franchise/SuperMarioBros'' has a constant echo behind her voice in several of her appearances, including her original debut in ''VideoGame/SuperMarioGalaxy''. Very appropiate, considering her place as [[TheHighQueen the Mother of the Cosmos]].
* ''VideoGame/SuperSmashBros''
** Character voices echo when they activate their powerful [[LimitBreak Final Smash]].
** Both [[Franchise/{{Pokemon}} Mewtwo's]] and [[Franchise/SuperMarioBros Rosalina's]] voice have a constant echo behind them. The former is [[OlympusMons a powerful psychic Pokémon]], and the latter is a {{Physical God}}dess.
* Anakaris, an ancient God-Pharoah Mummy in the ''VideoGame/{{Darkstalkers}}'' series speaks like this in the original Japanese versions.
%%* In ''VideoGame/MetroidPrime'', Dark Samus never speaks, but she laughs with a deep echoing sound.
%%* The Eldar of ''VideoGame/DawnOfWar'' all speak with a notable reverb.
%%** As do the Imperial Guard Psykers, when they're attacking or yelling.
%%** In the sequel, Kyras also speaks with a reverb. [[spoiler:It's evidently the Chaos taint]].
%% Yes, but how does that show power? Add context to these entries before readding them.
%% Please define context in the above.
%%* [[VideoGame/LeagueOfLegends "Immense power is fun! You should try it sometime!"]]
%%** [[OhCrap DAAAAARKNESSSS...]]
%% Just potholed quotes. The worst kind of Administrivia/ZeroContextExample.
* Inverted in [[DawnOfWar Dawn of War II]], as powerfully Chaos-aligned characters tend to have a reverse-reverb to their voices; in other words, you hear the echoes ''before'' they start talking!
* ''VideoGame/WorldOfWarcraft'': In the ''Wrath of the Lich King'' expansion, the voice of the Lich King -- EvilOverlord, PhysicalGod -- is accompanied by eerie and powerful echoes from every direction. It goes beyond the usual simple reverb. Additionally, when he's injured at the Wrathgate, you can perhaps hear two separate voices as he growls. He does have the souls of two beings combined.
** We learn later in the expansion that the echo is apparently coming from the Lich King's [[CoolHelmet Helm of Domination]] as in the ''[[https://www.youtube.com/watch?v=qAIrj_Vqdfc Fall of the Lich King]]'' cutscene which plays after his defeat, the helmet falls off of Arthas' head and his voice is back to his normal tone from before him putting the helmet on. Afterwards, when Tirion Fordring [[spoiler:puts the helmet on Bolvar Fordragon, players actually get to hear Bolvar's voice go from his current voice, to a downright ''demonic''-sounding growling rumble, with the echo kicking in towards the end of the sentence he says after having the helmet put on him.]]
** Members of the Infinite Dragonflight speaks with a heavy, reverberating echo.
* ''VideoGame/DiabloII'': Mephisto's voice has a kind of echo in the cinematic before the final act. It has a peculiar quality that, while not making it an actual BrownNote, somewhat fits the narrator's description of it being "like a thousand needles in my heart."
* ''VideoGame/TheLegendOfZeldaTwilightPrincess'': Midna has a subtle reverb to her voice. The Twilight Realm causes every sound to echo, but even in the middle of Hyrule Field, her voice retains the slight rumble, alluding to her potent magical abilities.
* The Liir of ''VideoGame/SwordOfTheStars'' are psychic and hermaphroditic, their "voices" not only echo but consist of a male and female speaking roughly [[VoiceOfTheLegion in unison]]. The telepathic predatory Zuul have an echo as well, and so do the [[EldritchAbomination Suul]]'[[SpaceWhale ka]]
* Characters in ''VideoGame/SuperRobotWars'' games who pilot {{Super Robot}}s tend to be given reverbs, even outside of [[CallingYourAttacks Calling Their Attacks]], in their voices as opposed to the more "mundane" RealRobot pilots. This happens even if the pilot never had one in their own series.
* In ''VideoGame/ShinMegamiTenseiIV'' and ''VideoGame/ShinMegamiTenseiIVApocalypse'', all demons speak with a distortion in their voice, whether through grunts or full words. ''Apocalypse'' does have one subversion in the form of Krishna - while both games' new designs made the demons look more alien, Krishna is the sole newly designed humanoid demon, so he lacks the echo. DLC also applies this to [[spoiler:the Demi-fiend from ''Nocturne'', a Half-Human Hybrid]].
* In ''VideoGame/PokemonXAndY'', A Pokémon's cry (the in-game "noise" that they make upon being sent out into battle) gains an echo when it [[SuperMode Mega Evolves]].

[[folder:Web Animation]]
* ''WebAnimation/IfTheEmperorHadATextToSpeechDevice'': Champion of Slaanesh, [[SissyVillain flamboyant]] rapist, and host of a Warp prank show, [[TabletopGame/Warhammer40000 Lucius the Eternal]] has a very soft echo behind his voice, heard clearly in his short. The Emperor has one himself, though his is more because the sound of his speakers echoing off the walls of his expansive throne room.

[[folder:Web Original]]
* ''Literature/WhateleyUniverse'' example: the [[spoiler:demon]] of "Ayla and the Grinch" speaks like this.
* Given that it's one long {{Homage}} to ''DragonballZ'' and the RuleOfCool in general, characters in ''WebAnimation/SuperMarioBrosZ'' have a tendency to do this when powered up. Mario in particular gets an impressive one when obtaining a ''[[MundaneMadeAwesome fire flower]]''.
* When using magic in ''Literature/{{Phaeton}}'' speech echoes, this is actually the sound of the voice extending to the various planes of existence.

[[folder:Western Animation]]
* In ''WesternAnimation/JusticeLeague'':
-->'''ComicBook/DoctorFate''': So fate demands! So... fate... demands...!
* Gwen, the MagicalGirl of ''WesternAnimation/{{Ben 10}}'', is quite possibly the current undisputed champion of this trope in the west.
* ''WesternAnimation/TeenTitans'': Raven, when she recites the spell to release Malchior and later to open the portal to Azarath.
* Spoofed in an episode of ''Disney/{{Hercules}}: The Animated Series'', in which the [[CrossoverCosmology Egyptian god Ra]] speaks with PowerEchoes, but after a while, presses a button on his staff that turns it off. He felt that while good for introduction, the echoing tends to grate on you.
* ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'': "I-I HAVE-AVE-AVE THE POWER-ER-ER-ER-ER-ER!!!!!"
* ''WesternAnimation/InvaderZim'': SPAAAAAAACE MEEEEEAAT!!!
** Not having access to that technology, they make theirs out of "Napkin".
* In ''WesternAnimation/ThePenguinsOfMadagascar'', "Two Feet High and Rising" features King Julien declaring a new law, and Maurice adds echoes for dramatic effect.
* ''WesternAnimation/{{Centurions}}'': "POWER EXTREME!-REME...reme...reme..."
* In an episode of ''WesternAnimation/TheTick'', when Arthur starts using Baron Violent's power belt, along with making him bigger, stronger and more aggressive, Arthur's voice starts to echo.
* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'': Parodied in the episode "The Secret Snake Club". Club leader "Wiggly" repeatedly refers to the club's secret "'''''AGENDA'''''"; each time he says the word "AGENDA," it's accompanied by a booming echo, dramatic chords, and lightning. After a few times:
-->'''Viper:''' I want to try that! '''''AGENDA!''''' ''[echo, chords, lightning]'' ...Neat!
** Wiggly gets fed up with this, and institutes a new rule...
-->'''Wiggly:''' From now on, '''I''' am the only one who can say '''''AGENDA''''' ''[abrupt echo/chords/lightning]'' you got that?
* ''WesternAnimation/BionicSix'': "Bionics On! On... on...on..."
* Magic-users of sufficient power have this in ''WesternAnimation/{{WITCH}}'' -- it's demonstrated by Cornelia when wielding the combined powers of the Guardians, Nerissa after absorbing the powers of the ''original'' guardians, Phobos both when he's combined his power and Elyon's and when using the Seal of Nerissa [[spoiler: and Cedric after eating Phobos and acquiring his ''and'' the Seal's power]].
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** [[GodEmpress Princess]] [[DarkIsNotEvil Luna]] '''[[NoIndoorVoice DOES THIS ALL THE TIME]]'''. She's struggling to break the habit after [[FishOutOfTemporalWater having been gone for one thousand years]], due to outdated royal protocols. She manages to rid herself of the echo eventually, but has more trouble shaking off the FloweryElizabethanEnglish that comes with it.
** [[SorcerousOverlord King]] [[DarkIsEvil Sombra]] mixes this with EvilSoundsDeep -- [[TheSilentBob when he even talks]], that is.
* ''WesternAnimation/BraveStarr'': "Strength of the Bear-ear-ear!" Likewise with Puma, Wolf, Hawk. Interestingly, the Shaman, when he gives Bravestarr the powers, has no need for added echo.
