->''"Go Lions, Brisbane Lions, we'll kick the winning score!\\
You will hear our mighty roar!"''
-->-- '''[[UsefulNotes/AustralianRulesFootball Brisbane Lions]]''' (to the tune of ''La Marseillaise'')

It's quite simple: Big monsters have big lungs, that let them make big noises. Sometimes [[CuteButCacophonic little monsters make big noises, too]], but that's neither here nor there. When a ''[[EverythingsBetterWithDinosaurs T. rex]]'', [[PantheraAwesome lion, tiger]], [[OurDragonsAreDifferent dragon]] or [[OurMonstersAreDifferent some other scary monster]] appears in a work that contains sound, it ''will'' make a mighty, [[NightmareFuel terrifying]], [[RuleOfCool awe-inspiring]] ROOOOAAAAAARRR!!!!

If the creature roars before attacking someone, it's RoarBeforeBeating. If the roar is unique to that certain creature and hard to confuse with anything else, it is SignatureRoar. However, if it's an animal that [[ArtisticLicenseBiology shouldn't be roaring at all]], see NoisyNature.


[[folder: Anime ]]

* While all of the titular [[HumanoidAbomination Titans]] in ''Manga/AttackOnTitan'' are capable of it, the one done by [[spoiler:Eren as]] the [[http://www.youtube.com/watch?v=h-ONY-B3I_Q Rogue Titan, stands head and shoulders above the rest]].
** And yet, [[http://www.youtube.com/watch?v=kl3rqzg_JVc&feature=youtu.be&t=4m25s it inspires awe and hope. Not just fear]].
-->'''[[ActionGirl Mikasa]]''': "...I was slightly exalted. Because what I was looking at felt like the [[EmbodimentOfVirtue reification]] [[LastStand of mankind's]] [[UnstoppableRage anger]]."
* The nine-tailed Kyuubi from ''Manga/{{Naruto}}'' deserves a mention with a roar [[http://www.youtube.com/watch?v=FTfP-pEwKl8 powerful enough to cause miniature destruction across its path.]]
* ''Anime/{{Pokemon}}'':
** Generally, if a Pokémon is not [[PokemonSpeak repeating it's name over and over again]] it has one of these.
*** Special mention to [[OlympusMons Palkia, Dialga, and Giratina]] for having {{Kaiju}} roars out of the ''Godzilla'' movies!
* In the movie remake of ''Anime/MagicalGirlLyricalNanohaAs'', the monstrous form of [[EldritchAbomination the Darkness of the Book of Darkness]] lets out animal-like roars during the final battle, in contrast to the banshee-like wails that the original TV version had.


[[folder: Films -- Animated ]]

* ''Disney/TheLionKing'' has these right on cue for each CrowningMomentOfAwesome. Though when Simba's still a cub, this ends up being an anticlimax. His "roar" is [[RuleOfFunny a kitten-like "Reeer!"]]. TruthInTelevision, as seen [[http://www.youtube.com/watch?v=FN7QpfboRMI here.]]
** When the hyenas were chasing Simba and Nala, Simba attempted to chase them off with a small roar, which the hyenas laugh at. He tries it again, this time with a [[PapaWolf startling]] [[DynamicEntry unexpected]] [[BigDamnHeroes surprise.]]
** And the AwesomeMomentOfCrowning at the end as pictured above, and boy is it ever.
* James P. Sullivan on ''WesternAnimation/MonstersInc.'' Comically averted by his [[{{Kaiju}} very tall friend]] Ted, who clucks. (They wanted the Godzilla roar, but couldn't get clearance.)
** In the credits, there's a blooper reel, in which [[WesternAnimation/ToyStory Rex]] auditions. He ''does'' roar. In his own...''special'' way.
* Toothless in ''WesternAnimation/HowToTrainYourDragon'' gives an ear splitter right into Hiccup's face before running off after he's cut loose.


[[folder: Films -- Live-Action ]]

* ''Franchise/{{Godzilla}}'' has [[SignatureRoar a unique roar]] [[MostWonderfulSound that all his fans recognize]]. And oh how [[https://www.youtube.com/watch?v=iXKKvgg-L6g mighty it is]]. Sounds like a freakin' jet engine.
** It sounds [[https://youtu.be/ihd_uzrX2Bw even cooler]] in the reboot.
** [[http://www.youtube.com/watch?v=hI1K-KNcJlw Not just him, either.]]
* As mentioned with the ''T. rex'' reference in the description, dinosaurs have a tendency to do this. ''Franchise/JurassicPark'' comes to mind as a specific example. In that case, it's most definitely a SignatureRoar, and what an epic one it is!
** This particular roar has been used and parodied in other mediums, especially by Rex in ''WesternAnimation/ToyStory3'' during their kid's imaginative adventures.
** Taken UpToEleven in ''Film/JurassicParkIII'' with the ''T. rex'' and the ''Spinosaurus'' roaring at each other during [[BehemothBattle their fight]].
** At the end of ''Film/JurassicWorld'', [[spoiler: the ''T. rex'' is shown on the heliport of the research building and making one last roar while looking over Isla Nublar.]]
* Film/KingKong isn't the quietest gorilla in the jungle, either, for that matter.
* The Creator/MetroGoldwynMayer film studio has a roaring lion at the start of each of its movies.
* Little baby Clover from ''Film/{{Cloverfield}}'' may have the most impressive set of lungs out of all the monsters. In fact one of the OST songs is explicitly called [[http://www.youtube.com/watch?v=s4p3rM9jOdE "Roar".]]
* The shark from ''Film/JawsTheRevenge'' actually roars like a lion in one of the most egregious cases of ArtisticLicenceBiology.
* Otherwise loveable Ben Grimm aka The Thing confronted a bear on the verge of attack in the second Fantastic Four movie; he freaked out the grizzly with a loud, animalistic roar which sent the brute in retreat!
* In the movie ''Film/{{Primeval}}'', VeryLooselyBasedOnATrueStory of a 20-ton giant man-eating crocodile in Africa, the giant reptile lets out a lion-like roar after devouring the BigBad.
* Invoked by the designers of ED-209 from the ''Franchise/{{Robocop}}'' films, who gave their giant security-robot the ability to project animal roars and snarls for intimidation purposes.
* King Louie from ''Film/TheJungleBook2016'' makes a really loud roar upon his emergence from his temple. This startles Bagheera, Baloo, and the monkeys from their battle before they could continue.
** Not long after that, Baloo roars at the monkeys, complete with standing on his hind legs, and stuns them. It doesn't last long because [[FunnyMoments the monkeys immediately dog-pile him afterwards]].


[[folder: Literature ]]

* ''Literature/TheChroniclesOfNarnia'': [[CrystalDragonJesus Lion Jesus]] Aslan has one of these.
* ''Literature/{{Temeraire}}'' combines this with MakeMeWannaShout.
* Literature/{{Tarzan}} has his signature roar, described in the book as the victory cry of a bull ape. Unique example in that the character is a human, [[FeralChild though he was raised as an animal]].
* A staple in ''{{Literature/Dinoverse}}''. Inevitably someone's put into the body of a big Tyrannosaurus-like dinosaur and at some point roars horrifyingly loudly.
* Mouse in ''Literature/TheDresdenFiles'' has the ability to generate a magical bark. When he was a puppy small enough to fit in a pocket, his bark could be heard throughout a large building loudly enough to wake sleepers and trigger car alarms in the street outside. Mouse, fully grown, stands in excess of three feet at the shoulder and weighs over twohundred pounds, and his bark is loud enough to transcend the borders between dimensions.


[[folder: Live Action TV ]]

* Rover on ''Series/ThePrisoner'' has a distinct and decidedly creepy roar (perhaps made creepier by the fact that Rover is a sentient weather balloon).
* Several ''Franchise/PowerRangers'' [[AnimalMecha animal zords]] roar. First and foremost are the Wild Zords of ''Series/PowerRangersWildForce''; the main Megazord's regular FinishingMove is even the component zords roaring FrickinLaserBeams.
* Done for sheer RuleOfCool on ''Monster Bug Wars'', which dubs ferocious sound effects onto footage of [[MundaneMadeAwesome tiny creepy-crawlies preying on each other]].
* Worf from ''Series/StarTrekTheNextGeneration'' has one, which he uses to demonstrate Klingon mating behavior (minus the furniture-throwing).


[[folder: Video Games ]]

* In ''VideoGame/StarFoxAdventures'', the King Redeye puts his head into the room to roar before fully entering. On an earlier note, the Galdon does some roaring, as well.
* ''VideoGame/{{Pokemon}}'' has the move Roar, which makes the opponent Pokemon switch or flee the battle. Of course, it's learned by a lot of big Pokemon, but is specially notable on the legendary beasts of [[VideoGame/PokemonGoldAndSilver the second generation]], [[ThatOneBoss which use it to escape from you if you ever find them and block their exit]].
** Bizarrely, the [[{{Kitsune}} Vulpix line,]] [[HeroicDog Lillipup line, Growlithe line]], [[BullyBulldog Snubbull line]], [[{{Hellhound}} Houndour line]] and Te''pig'' line learn this move. Apparently in the Pokemon world dogs and pigs roar.
** The [[PantheraAwesome Litleo line's]] SignatureMove is Noble Roar, which lowers both of the attacking stats of a foe.
* ''VideoGame/{{Okami}}'':
** Their very own {{Orochi}} has one, and it's the key to defeating him. When he roars, your pour Sake into his mouth to lower his barrier.
** Gekigami has one of these. Fitting, as he's a tiger god of thunderstorms.
* From ''VideoGame/SengokuBasara'', the White Tiger's most powerful attack in an awesome howl that knocks you back several feet and makes the ground tremble.
* In ''VideoGame/{{Spore}}'', the special ability in the creature stage that is rewarded upon completing cell stage as a carnivore is [[NamesToRunAwayFromReallyFast Raging Roar]], which makes all nearby creatures run away in fear.
* While Asura in ''VideoGame/AsurasWrath'' usually does a lot of screaming, [[spoiler:his transformation into Berserker asura destroys tons of ships just from its shockwave. [[UpToEleven When they are above the earth's Orbit.]] It's his default scream in Berserker form as well.]]
* Chimeras in ''VideoGame/DragonsDogma'' are able to roar with their lion head, which will cause any character nearby to fly away. However, characters clinging to its body are exempt, and heavier characters don't fly as far as lighter ones. The roar doesn't do any damage itself, but the time it takes to get up could be enough for the chimera to make another attack.
* Subverted by the [[TyrannosaurusRex Tyranto Rex]] dream eater in ''VideoGame/KingdomHearts3D''. Big and scary it is, but it sounds like an angry house cat. On the other hand, it can still "roar" loudly enough to stun its foes for one of its attacks.
* In ''{{VideoGame/Starbound}}'' lore the Apex, a technologically advanced humanoid race of monkey people, can indeed roar.
* In ''Videogame/{{Evolve}}'' the monsters roar after evolving, a sound loud enough to be heard anywhere on the map. As to why they do it, it's a mixture of pain from the evolution process and a warning to anything within earshot that they're more dangerous now.

[[folder: Webcomics ]]

* Rak, a giant Gozilla-like alligator from ''Webcomics/TowerOfGod''.
** Then there's various beasts such as the [[GiantFlyer White Steel Eel]], [[CallASmeerpARabbit the Bull]] and [[OlympusMons Zygaena]].


[[folder: Web Original ]]

* RUMBLEROAR!!! from a very memorable scene in ''Theatre/AVeryPotterMusical''.
* WebVideo/TheAngryVideoGameNerd leads an army of Gamers into battle with one in the WebVideo/TGWTGYearOneBrawl.


[[folder: Western Animation ]]

* In ''WesternAnimation/TheLionGuard'', Simba's son Kion takes it UpToEleven with the Roar of the Elders, which is powered by the spirits of past lions.
* ''WesternAnimation/{{Gargoyles}}'' let loose a MightyRoar when they wake in the evening. They can also make some pretty bestial sounds depending on how ticked off they are.
--> Goliath: "A gargoyle does not whine.... he '''ROARS'''!"
* [[KingOfBeasts Leobreaker]] and [[OurDragonsAreDifferent Scourge]] of ''Anime/TransformersCybertron'' can let out some pretty impressive roars.
* A CrowningMomentOfAwesome moment happens in the ''WesternAnimation/TomAndJerry'' episode "The Milk Waif" where Tom sets off Jerry's BerserkButton when witnessing him slapping baby orphan mouse Nibbles with a flyswatter. In a rage he lets out a ferocious roar before pummeling the cat into submission.
* The shark-men heroes from ''WesternAnimation/StreetSharks'' bellow roars.
* In ''WesternAnimation/TheLegendOfKorra'', the heroine of the title calls in her polar bear dog to deliver one of these when being confronted by JerkAss PrettyBoy Tahno, who gets scared off by it along with the rest of his team.
* Timber Wolf in ''WesternAnimation/LegionOfSuperHeroes'' does this a few times in the series, fitting seeing he's the team's feral member (to the point where [[ShipTease Phantom Girl]] nicknames him [[LampshadeHanging 'Simba']] in the comic book adaption of the series). One of the more noteworthy examples is when he confronts his father in his lab he roars at the animal test subjects ([[TooDumbToLive his Dad wanted to unleash the animals on the Legion but they decided they'd rather go after him instead]]) forcing them to back off in fear.
* Although the titular Beast in ''WesternAnimation/MaggieAndTheFerociousBeast'' is a very [[GentleGiant gentle and kind creature]], he ''does'' have a Ferocious Roar.
* ''WesternAnimation/TheSimpsons''
** In "Some Enchanted Evening", as Marge waits impatiently for Homer to get home, she unleashes a ferocious roar at her kids when they ask her to make them dinner.
** Marge pulls one again in "Homer Alone" when, following a mental breakdown, she stops her care in the middle of traffic and roars at an irate driver who yells at her.


[[folder: Real Life ]]

* The lion has the loudest roar of all the big cats which can be heard up to 5 miles away. The other big cats aren't so bad either.
* Bull crocodilians pump up the volume on their usual rumbling vocalizations when contending for mates or territory.
* Low-pitched elephant trumpets may qualify
* Male orangutans have a massive, low-pitched call they use to mark their territory.
* Howler monkeys- small animal but big sound. Their cries are considered to be the loudest of any land animal, clearly audible for more than three miles (it doesn't have quite as much range as a lion's roar because it's higher in pitch and the rain forests the howler monkeys live in muffle the sound more quickly than the savannas that lions inhabit).
