When a martial artist is extremely focused, an ethereal creature can be seen behind him, roaring, rearing, or screaming. Often used to show that the martial artist is mimicking something about the creature or (in more supernatural kung fu movies) channeling the trait from the creature. If taken less symbolically, the aura can accompany a powerful attack, [[ShapingYourAttacks be physically 'launched' at enemies to damage them]], [[BattleAura surround the person generating it and mimic their movements]], or even [[FightingSpirit act independently as an attack animal]].

A subtrope of PowerGlows. Actually-visible auras can overlap with ShapingYourAttacks.

[[folder: Anime and Manga ]]

* ''Manga/{{Naruto}}'':
** The Kyuubi chakra is one such example, growing more defined as Naruto gets older and uses more and more of its power. The first time he taps into its chakra, his BattleAura briefly forms an enormous demonic fox head above him before subsiding. When he fights Sasuke at the Valley of the End, his aura resembles a one-tailed version of the Kyuubi and is capable of moving independently of his body. Post-TimeSkip, we see that he can sprout up to three chakra tails and still be (mostly) himself - if it gets to [[FourIsDeath four]], the aura is replaced by a OneWingedAngel transformation. The use of an aura and transformation are common among the jinchuuriki.
** [[spoiler:Naruto]] gained the ability to manifest a {{Kaiju}}-sized BattleAura in the form of his bijuu. Most jinchuuriki instead manifest a physical form of their bijuu.[[note]]According to Kurama, this is because they haven't practiced it yet and the transformation is imperfect.[[/note]]
** When extremely focused, Zabuza can manifest an ethereal demon's face from his KillingIntent, terrifying opponents with a weak will. Early in the manga this is played as due to how intimidating he was, but it is confirmed as an actual technique [[spoiler:when he is brought back with the Edo Tensei]].
** Hinata's Twin Lion Fists - exactly what it sounds like.
** Might Guy's [[LimitBreak Afternoon Tiger]] technique is a punch that compresses air into a giant tiger head. Unlike the others, there's no chakra involved in the tiger - once he opens enough [[DangerousForbiddenTechnique Gates]], the sheer force of his blows can force the air into these shapes.
* Yachiru of ''Manga/{{Bleach}}'' has an angry cat aura in the show and some of the fighting games. Since we haven't actually seen her fight until the Thousand Blood War arc, this becomes her more powerful attacks in those games.
* ''Manga/RurouniKenshin'': Kenshin occasionally gets a dragon aura, and Enishi's had a tiger aura at least once as well.
* Parodied in ''RanmaOneHalf'': the enemies radiate a fearsome, intimidating auras of powerful beasts --a dragon, a wolf, and a tiger-- with a [[UnsoundEffect LOOOOOOOOM]] sound effect. The heroes ''try'' to do the same with the auras of... girl Ranma at her adorablest, and an equally cute duck and pig, and a much smaller [-LOOOOOM-] effect.
* ''SaintSeiya'': Most of the Saints' patron constellations represent an animal or mystical creature; in the case of [[MonsterOfTheWeek minor foes]], the appearance of said creature in their [[BattleAura Cosmo]] is merely for intimidation, but when a Gold Saint or a main character does it, it typically heralds a [[LetsGetDangerous serious turn of the tide]] in the duel. Furthermore, the vast majority of signature attacks, such as the [[RapidFireFisticuffs Pegasus Ryusei Ken]], [[{{Shoryuken}} Rozan Shoryu Ha]], [[BrainwashedAndCrazy Phoenix Genma Ken]], [[PlayingWithFire Hou Yoku]] [[BlowYouAway Tensho]], and [[AnIcePerson Diamond Dust]], tend to manifest visible auras as the Saint delivers it (in the above examples, the Pegasus, an enormous Chinese Long, the Phoenix, or a swan).
* ''Manga/YuYuHakusho'':
** Yusuke's aura manifests as a phoenix near the end of the Dark Tournament.
** When Hiei uses the Dragon of the Darkness Flame against Bui, this effect happens with, you guessed it, a dragon.
** In the very first match of the Dark Tournament, Rinku, who manipulates yo-yos that can twist in the air like snakes, briefly manifests a hissing ethereal red snake behind him during the fight, at least to Kuwabara's eyes.
* Parodied in ''Manga/HayateTheCombatButler'' : [[TheGenericGuy Nishizawa]]'s animal battle aura is a ''cute little hamster''. Which causes Nagi to thoroughly mock her and nickname her "Hamster".
* In ''HajimeNoIppo'', boxer Sendo Takeshi's nickname is "The Naniwa Tiger". Try to guess what his battle aura looked like to Ippo.
* Early in ''Manga/{{Parasyte}}'', when provoked, the titular aliens project creatures behind them (a metaphor for their predatory bearing). One gives off a tarantula just before murdering a lion, and the main character shows a praying mantis before punching someone out.
* Musubi from ''{{Sekirei}}'' has a bear aura, and all of her special attacks are bear-themed. The aura was even seen crying in a recent chapter when Musubi herself was upset.
* Happens quite often to Zoro in ''Manga/OnePiece'', with a variety of animals depending on what attack he is using, from a dragon, to a bull, to a [[AGodAmI demon god]]...
* When Yamcha from ''Manga/DragonBall'' uses his Wolf Fang Fist, he appears to take on the appearance of a wolf. Some of the fighting games replicate this imagery with a more standard AnimalBattleAura.
** Goku himself had a visible aura of his [[InvoluntaryShapeshifting were-ape]] form when he punched through King Piccolo. Whether his movie / GT-exclusive Dragon Fist technique counts is debatable - in the movie it first appeared in, he briefly *became* a giant gold energy dragon, but in GT he would just as often simply summon it.
* Natsu from ''Manga/FairyTail'', when using a dramatic enough attack, will often be shown with a ghostly/flaming image of Igneel superimposed over him.
** When Natsu, Gajeel and Wendy fight Faust, all three of are shown with their foster dragon-parent aura.
* CaptainTsubasa's Tiger Shot, Falcon shot, Eagle Shot, and even Banana shot, which has monkeys dancing around in the series's games.
* {{Beyblade}}s with Bit Beasts have these.
* Intimidations from ''{{Toriko}}''. They coincide with the person's GameFace.
* ''Franchise/LyricalNanoha'':
** Rio Wesley of ''Manga/MagicalGirlLyricalNanohaVivid'', whose ranged attacks take the form of dragons.
** Signum in ''Anime/{{Magical Girl Lyrical Nanoha The Movie 2nd As}}'', her Sturmfalken ultimate attack is depicted as taking the form of a [[HotWings fire bird]].
* In ''Manga/FullmetalAlchemist'' Buccaneer has a bear-aura. It suits him quite well.
* In ''Manga/HunterXHunter'', Killua has a so strong KillingIntent, his aura looks like a giant snake when Rammot faces him.
** Neferpitou's aura usually looks like a demon. If [[AmbiguousGender his/her]] protection instict is strong enough, his/her aura takes the form of a cat mother, fitting to the fact that Neferpitou is a cat-human-etc.-hybrid-ant.
** Gon, when he's '''really''' pissed of, has an aura compared to a tiger.
* ''LightNovel/LogHorizon'': PlayedForLaughs in episode 7 -- Shouryuu and Hien briefly manifest a wolf and fox head, respectively, in their auras while they DeathGlare at each other.

[[folder: Comicbooks ]]

* In MarvelComics the [[Comicbook/XMen Phoenix Force]] surrounds its wielders with a fiery birdlike aura, most commonly when they are using the power aggressively. Depending on how much power they are channeling it can be larger than planets.

[[/folder]]

[[folder: Film ]]

* In ''ShaolinSoccer'', a goal shot goes so fast the ball bursts into flames, which then take the shape of a [[ProductPlacement roaring puma]]. Undoubtedly as a parody of CaptainTsubasa.
** Later in the same match, the captain of [[MeaningfulName Evil Team]] generates a black aura of such concentrated badness it takes on the shape of a demon before being sucked into the ball.
* Parodied in HotRod where Rod calls upon animal spirits before his stunt jumps (most of which he fails miserably). The animals are almost completely random -- for instance, the octopus and the house cat.

[[/folder]]

[[folder: Literature ]]

* ''Literature/HarryPotter'': The Patronus spell, a magical guardian created from good memories to repel [[EmotionEater Dementors]], takes the shape of an animal. It usually represents either the person casting it or someone close to them - Harry's is a stag, representing his dead father's Animagus form - and can change form following an emotional upheaval.
* Happens frequently in Fiona Patton's TalesOfTheBranionRealm. Two Gods, one represented by a white dragon, the other by a crimson fire-wolf, often take human champions and clash overhead, mirroring the real-life battle below.

[[folder: Live Action TV ]]

* Used as a one-off in the finale of ''Series/PowerRangersDinoThunder''. After Mesogog's OneWingedAngel form not only tanks their entire arsenal but starts ''multiplying'', the Rangers channel all their power into one final attack. This takes the form of a glowing T-rex who swallows Mesogog before the obligatory explosion.
* Use of the Animal Battle Aura is ''the'' [[SupernaturalMartialArts Supernatural Martial Art]] taught in ''Series/JukenSentaiGekiranger''/''Series/PowerRangersJungleFury''. The Rangers can not only sic their auras on enemies, but give them physical form and make them HumongousMecha.

* In ''WorldOfWarcraft'' skilled hunters can aspect-dance. Switching aspects causes a sound to play and a picture to appear. Needless to say, frenzied aspect-dancing, while super-rare, looks really cool.

[[folder: Tabletop Games ]]

* ''{{Exalted}}'': The Anima Banners of Solars and Lunars are "iconic"--that is, at their brightest, they manifest as a coherent image that reflects on that particular Exalt's nature. For Solars, this can be anything--examples include symbolic animals, complex mandalas, mazes of ice, and many others. For Lunars, this is always their spirit shape, their [[ShapeshifterDefaultForm default animal form.]] Abyssals also have iconic anima banners, but they tend to be more death-related imagery, and sometimes a corruption of the former Solar banner -- skulls, corpses, wraiths, funeral shrouds, and the like. Green Sun Princes tend to have imagery styled after their Yozi patron, including demons descended from that particular Yozi. Alchemicals generally have industrial-themed imagery -- machinery, electricity, smoke, steam, etc. Sidereals and Dragon-Blooded never have iconic anima banners (except a few Dragon-Bloods who have a representation of an Elemental Dragon), so this is one of the characteristics the Wyld Hunt uses to identify Anathema.
* The [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=193635 Umbra auras]] of the ''[[MagicTheGathering Magic: The Gathering]]'' Rise of the Eldrazi set let you give any creature one, and impart some of the abilities of the aura's shape, along with a one-time protection from destruction.

[[/folder]]

[[folder: Video Games ]]

* This is the big feature of ''BlueDragon'', basically.
* Captain Falcon's Falcon Punch in the ''VideoGame/SuperSmashBros''. series is surrounded by a giant, flaming falcon.
* All fighters in ''VideoGame/BlazBlue'' have a seal that glows behind them when they perform a [[LimitBreak Distortion Drive]] or [[OneHitKill Astral Heat]]. Not all of them are animal-themed, but this trope is in full force for Hakumen's wolf seal, Arakune's spider seal and Hazama's snake seal. Ragna's seal is [[spoiler: the Black Beast itself.]]
* InazumaEleven, which follows the concept of CaptainTsubasa, turn it UpToEleven. As the matches in the game are almost as deadly as wars.
* Sabin's Tiger Break DesperationAttack in ''VideoGame/FinalFantasyVI''.
* Employed in the "Thrill" stage of ''OsuTatakaeOuendan'', during a [[MundaneMadeAwesome particularly heated game of dodgeball]].
* A number of entries in the ''Franchise/TalesSeries'' features the physical arte Beast, which sends a burst of spiritual energy in the shape of a lion's head flying at the enemy. Variations that use other animals like wolves or dragons also exist.
** There's also the Rising Phoenix arte, that surrounds the user with a fiery phoenix as they dive into the target.
* In ''{{Too Human}}'', the human path enables you to use the spiritual devastators which include a [[CreepyCrows crow]] a [[NobleWolf wolf]] and even a {{bear|sAreBadNews}}!.

[[folder: Web Comics ]]

* Laika from ''[[TsunamiChannel Experimental Comic Kotone]]'' does this once to scare away some guys.

[[/folder]]

[[folder: Western Animation ]]

* Ron Stoppable from the ''KimPossible'' series finale does this when he goes into Monkey Mode.
* ''{{Metalocalypse}}'': Slightly subverted in the episode "Dethcarraldo". Dethklok takes a drug called Yopo that gives them visions of their animal selves, made obvious by the fact that the animals are anthropormorphic caricatures.
** Nathan Explosion is a crocodile.
** Pickle's the Drummer is an octopus (with much resemblance between the tentacles and his dreadlocks).
** William Murderface is a tiger (whose head is exactly the same).
** Toki Wartooth is a...um...rabbit? (Other than the ears and Toki's face, it's very difficult to tell.)
*** He's a rabbit, with feathers stuck to him.
** Skwisgaar Skwigelf is an owl (with the same blonde hair).
* ''JusticeLeagueUnlimited'' uses this trope to represent Vixen's powers.
* When Chiro from ''SuperRobotMonkeyTeamHyperforceGo'' taps into the Power Primate, a giant green energy-gorilla forms around his body. When he pushes his abilities even further, he forms the aura and then pulls it back into himself.
* ''WesternAnimation/TomAndJerryTheMovie'': "It soars through my mind like a beautiful bird..."
