->''"Who are you?\\
Who, who, who, who\\
I really wanna know..."''
-->-- Music/TheWho, "Who Are You"

TheHero has burst into the scene, has saved the girl, and is holding the villain at [[CoolSword sword]][=/=][[CoolGuns gun]]-point. The villain (or maybe some other bystander), bewildered, demands "Who are you?" The hero usually responds with a BadassBoast, although a big monologue is not necessary. Sufficiently awesome heroes can get away with [[MyNameIsInigoMontoya just their name]], which is especially effective if it's [[EstablishingCharacterMoment the first time the audience is hearing it]], or [[MeaningfulRename the first time the character has referred to himself by that name.]] A common subversion is when the boast is [[NegatedMomentOfAwesome interrupted]]. If the hero's actions are especially amazing, the villain may demand, "WhatAreYou?" instead.

PrecisionFStrike is sometimes employed when asking the question. Can also overlap with WhoDares.

Not to be confused with the [[AwesomeMusic ridiculously awesome]] song and album by Music/TheWho, or with the KoreanDrama ''Series/WhoAreYou''.



[[folder:Anime & Manga]]
* In the opening of ''Manga/RurouniKenshin'' ''Trust and Betrayal'' OVA, a mysterious swordsman saves Kenshin from being killed by bandits. Just before being killed, the last bandit asks the stranger who he is. The swordsman (who is later revealed to be Hiko Seijūrō), replies "You won't live long enough to remember my name."
* In ''Lightnovel/FullMetalPanic'' when a {{Mook}} asks Sosuke who he is, he replies in a cool voice: "I'm the garbage man." This is a reference to his being assigned school garbage collection duty.
* Inverted or...something in ''Anime/TengenToppaGurrenLagann''. The hot-blooded heroes were rarely actually asked, but often answered their opponents preemptively [[LargeHam and at great length]], always ending with the series' CatchPhrase / ArcWords, "JUST WHO THE HELL DO YOU THINK WE ARE!?"
* ''Manga/FullmetalAlchemist'':
** The resident ActionMom, Izumi, gives this response:
--->'''Izumi:''' Normally, I'd say "just a housewife", but today, I feel like showing off: '''[[PreAssKickingOneLiner I'm an alchemist.]]'''
** Her normal (utterly terrifying) response to 'what are you' ''was'' "a housewife." And it's true. She's HappilyMarried to a strong, silent-type meat butcher and is great with the local kids (though horrifyingly abusive toward her students)... and everything else in the series that isn't an EldritchAbomination finds reason to fear her.
** Tragically, she never ''will'' be an ActionMom. Or any other kind of mom. Except potentially adoptive, but she doesn't seem interested in that.
* ''Franchise/SailorMoon'' villains were fond of this one. The hero who got this the most was Tuxedo Mask.
* In ''[[Toys/MachineRobo Machine Robo: Revenge of Cronos]]'', any villain to receive a lecture by Rom Stoll will often demand to know who the hell Rom is, to which his reply would invariable be "YOU DON'T DESERVE TO KNOW MY NAME!" before Rom began kicking ass. This also extends to anyone in ''VideoGame/SuperRobotWars'' that got a lecture from Rom... even an [[Anime/NeonGenesisEvangelion Angel]].

[[folder:Comic Books]]
* The first issue of ''ComicBook/AllStarBatmanAndRobinTheBoyWonder'' included this [[MemeticMutation memetic]] exchange (which, [[StealthParody for better]] or for worse, effectively set the tone for the series as a whole):
-->'''Dick Grayson, [[RunningGag Age 12]]:''' Who the hell are you anyway, giving out orders like this?\\
'''Batman:''' What are you, ''dense''? Are you ''retarded'' or something? Who the hell do you ''think'' I am? I'm the Goddamn ''Batman''.
* In ''ComicBook/{{Supergirl}}'' story arc ''ComicBook/RedDaughterOfKrypton'', Kara Zor-El stops an out-of-control Red Lantern who is about to fry an innocent woman's mind.
-->'''ComicBook/{{Supergirl}}:''' That's enough!\\
'''Sheko:''' Who are you?\\
'''Supergirl:''' My name is Kara. I am a Red Lantern, just like you.\\
'''Sheko:''' ... Red... Lantern...?

[[folder:Fan Works]]
* ''Fanfic/KyonBigDamnHero'' has this exchange just after Kyon [[DynamicEntry arrivies]] to save Tsuruya and her bodyguard from a dozen {{Yakuza}}:
-->'''Yakuza Mook:''' You've bought yourself ten seconds, and a one-way ticket to a world of hurt, kid. Who the hell do you think you are?\\
'''Kyon:''' Today, I'm a defender of justice, and that girl's guardian. Cliche though it may sound... from this point on if you want to get to her, or him, you go through ''me''.
* In chapter 29 of ''Franchise/{{Superman}}'' fanfic ''Fanfic/SupermanOf2499TheGreatConfrontation'', Katherine saves a woman from a rapist, and her rescuee asks who she is.
-->'''Katherine:''' I will take you to a place of safety, to a police station. Give them this thing he was going to use on you. Tell them about him. If you donít, heíll only do this again when he recovers. Do you understand? Give me your word youíll do this.\\
'''Woman:''' Iíll, Iíll do it. Who are you? Are you an angel?\\
'''Katherine:''' No.\\
'''Woman:''' Then who are you?\\
'''Katherine:''' ComicBook/{{Supergirl}}. Call me Supergirl.
* From ''FanFic/AGrowingAffection'':
-->'''Ninja Reaper:''' It is over, ninja. Give me your name, that I may remember it.\\
'''Naruto:''' My name is Naruto Uzumaki. And there's no way I'm going to die here. I'm going to be the next Hokage.

[[folder:Films -- Animation]]
* ''Disney/{{Mulan}}'': Mushu heads over to the fireworks area during the final battle, and is asked by the guards there, "Who are you?" He responds, "Your worst nightmare," and they flee.
* Rafiki does this with Simba in ''Disney/TheLionKing'' in a non-evil variation.
-->'''Simba:''' Creepy little monkey. Who are you?\\
'''Rafiki:''' The question is, who are you?
* ''WesternAnimation/{{Hoodwinked}}!'' has a variant in the form of Red Puckett's reaction to seeing the Wolf [[PaperThinDisguise impersonating Granny]]:
-->'''Red Puckett:''' What? Who are you?\\
'''The Wolf:''' I'm your grandma.\\
'''Red Puckett:''' Your face looks really weird, granny.\\
'''The Wolf:''' I've been sick, I... uh... ''[puts his hands over his chest]''\\
'''Red Puckett:''' Your mouth doesn't move when you talk.
* Said by Tai Lung in ''WesternAnimation/KungFuPanda'' when Po interrupts him while he's choking the life out of Master Shifu when he doesn't divulge the location of the Dragon Scroll.
-->'''Tai Lung:''' Who are you?\\
'''Po:''' Buddy, I... am the Dragon Warrior! ''[bows over, panting over from climbing the stairs]''\\
'''Tai Lung:''' ''[incredulous]'' You? ''[[[EvilLaugh laughs]]]'' He's a panda! You're a panda! What are you gonna do, big guy? Sit on me?\\
'''Po:''' [[InsultBackfire Don't tempt me.]]
* ''WesternAnimation/YellowSubmarine'': When the Beatles confront the Boob, who hands them separate calling cards:
-->'''John:''' And who in Billy Shears are you?\\
'''Boob:''' Who? Ah... who indeed am I. ''[hands out cards to each of the boys, who reads them out loud]''\\
'''John:''' Jeremy?\\
'''Paul:''' Hilary?\\
'''George:''' "Boob"??\\
'''Ringo:''' ''[on his card which reads "Ph.D."]'' "Fffffud."\\
'''All four together:''' Who???\\
'''Boob:''' Eminent physicist, polyglot classscist, prize-winning botanist, hard biting satirist, talented pianist... good dentist, too.

[[folder:Films -- Live-Action]]
* ''Film/PiratesOfTheCaribbeanTheCurseOfTheBlackPearl'' has this, aimed at Will Turner. It features a mild subversion, with Jack trying very hard to keep Will from answering, since it will [[KansasCityShuffle derail his plans]].
-->'''Barbossa:''' Who ''are'' you?\\
'''Jack:''' Nobody! He's nobody! [[HurricaneOfExcuses Distant cousin of my aunt's nephew, twice removed]]. Wonderful singing voice, though. ''[[RunningGag Eunuch]]''.
* ''Film/KickAss'' has this a couple times. First when Kick-Ass saves the guy outside the store, and the guy with the camera phone says it:
-->'''Bystander:''' Dude, who are you?\\
'''Dave:''' I'm ''Kick-Ass''.
* ''Film/LawrenceOfArabia'' uses this far too many times to count. Once even before the film transitions into the extended flashback that makes up the vast majority of it.
* From ''Film/RamboIII'':
-->'''Zaysen:''' Who are you?\\
'''Rambo:''' Your worst nightmare.
* ''Film/ThePrincessBride'':
-->'''Inigo:''' Who ''are'' you?\\
'''Man in Black:''' No-one of consequence.\\

* From ''Film/SgtKabukimanNYPD'':
-->'''Mook:''' Who are you?\\
'''Kabukiman:''' ''*AsideGlance*'' I'm Kabukiman.
* At the beginning of the first ''[[Film/TheNakedGun Naked Gun]]'' movie after beating up the various Arab leaders, Idi Amin and UsefulNotes/MikhailGorbachev:

* From ''Film/{{Hook}}'' while Peter Pan is swordfighting a pirate mook:

'''Pan:''' Peter Pan.\\
'''Pirate:''' [[ScrewThisImOuttaHere AHHHHHHHHHH]]! ''[[[DestinationDefenestration jumps out the window]]]''
* ''Film/HighPlainsDrifter''. "WWHHHOOOOO ARRRRRE YOUUUUUU!"
* Both the 1989 ''Film/{{Batman}}'' and ''Film/BatmanBegins'' feature the classic Batman introduction:
-->'''Crook:''' What are you?!\\
'''Batman:''' I'm Batman.
* ''Film/CrouchingTigerHiddenDragon'' features perhaps one of the lengthiest and floweriest examples of this trope:
-->'''Monk:''' Who are you?\\
'''Jen Yu:''' ''[while menacingly unsheathing her sword]'' You want to know who I am? I am... I am the Invincible Sword Goddess, armed with the Green Destiny that knows no equal! Be you Li or Southern Crane, bow your head and ask for mercy! I am the dragon from the desert! Who comes from nowhere and leaves no trace! Today I fly over Eu-Mei. Tomorrow... I topple Mount Wudan!
* ''Film/TheWizardOfOz'' has this:
-->'''Oz''' I am Oz. The great and powerful. Who are you?\\
'''Dorothy:''' I'm Dorothy, the small and meek.
* ''Film/VForVendetta'': V's EstablishingCharacterMoment involves lampshading the FridgeLogic in play:
-->'''Evey:''' Who are you?\\
'''V:''' Who? "Who" is merely a form following the function of "what," and ''what'' I am is a man in a mask.\\
'''Evey:''' I can see that.\\
'''V:''' Of course you can. I'm not questioning your powers of observation, I'm merely remarking upon the paradox of asking a masked man ''who'' he is.
* ''Film/ShootEmUp''. Mr Smith replies, "I'm a British nanny, and I'm dangerous."
* Major gets asked this several times in ''Film/GhostInTheShell2017''. The question is [[FakeMemories more relevant than she thinks.]]
* In the film version of ''Franchise/TheWitchesOfEastwick'':
-->'''Alexandra:''' Who are you?
-->'''Daryl Van Horne:''' Just your average [[HotAsHell horny little devil]].
* ''Film/TheNameOfTheRose''. Novice monk Adso is seduced by a beautiful nameless peasant girl.
-->'''Adso:''' ''(narrating)'' Who was she? Who was this creature that rose like the dawn, was as bewitching as the moon, radiant as the sun? [[SexIsEvilAndIAmHorny Terrible as an army poised for battle.]]
* Played for laughs in ''Film/GuardiansOfTheGalaxy'': Peter Quill is captured taking the Infinity Stone in the opening scene by Korath the Pursuer, who demands to know who he is. Peter dramatically identifies himself as Star-Lord, but rather than impressed, Korath and his men are just confused, much to Peter's exasperation.
-->'''Korath the Pursuer''': Who are you?\\
'''Peter Quill''': There's one other name you might know me by... Star-Lord.\\
'''Korath''': ...Who?\\
'''Peter''': Star-Lord, man. Legendary Outlaw.\\
''Korath and his {{mooks}} shrug helplessly.''\\
'''Peter''': ... Guys?

[[folder:Live-Action TV]]
* ''Series/KamenRiderDecade'' gets this question [[PhraseCatcher a lot]] (usually preceded with a [[UsefulNotes/JapanesePronouns rude pronoun]]) when he finishes his KirkSummation. The correct answer is, "Just a passing-through Kamen Rider. Remember that!"
* ''Series/DoctorWho'': The Doctor is another frequent recipient. How he replies depends on his personality at the time.
** The Doctor also asks this of River Song several times, until he finds out in series 6.
** In "Oxygen", the Doctor responds with a BadassBoast to this question, saying he's going to save them so they'll spend the rest of their lives wondering about that.

* One of the sets of ArcWords on ''Series/BabylonFive'', along with "[[DealWithTheDevil What Do You Want?]]" and "[[ArmorPiercingQuestion Why Are You Here?]]" In contrast to its typical usage, giving your name or title is highlighted as being the wrong answer to the question.
* ''Series/BurnNotice'', the episode "Center of the Storm"
-->'''The Client:''' Who are you?\\
'''Michael Westin:''' I'm Michael Westin, and I'm here to save you people.\\

'''Michael Westin:''' ''*sigh*'' I'm Michael Westin, and I'm here to save these people.
* Happens on ''Series/{{Leverage}}'' with Damian Moreau in season 3 after the [[JustLikeRobinHood heroes]] spent the entire third season taking him down. He has no idea who any of them are[[spoiler: except Eliot]].
* ''Series/PersonOfInterest''. [[https://www.youtube.com/watch?v=QNvP35v3lS4 When asked this question]], Reese muses that he really needs to think up an answer to give people, although his usual response is some variation on "[[CatchPhrase a concerned third party]]". Played seriously in a later episode when he replies, "I find it hard to answer that, even to myself." And in "Trojan Horse" he's being shot at when asked this question, so he replies, "Right now? An easy target."
** In "RAM", we see Reese's predecessor on the job saving a DamselInDistress, and he smoothly answers, "Protector of the innocent. Heard you could use some protecting", before talking her into RescueSex, [[EstablishingCharacterMoment showing he's more arrogant and less moral]] than Reese.
** Harold Finch is the inventor of The Machine, for which he charged the US government a nominal fee.
-->'''Barnett:''' Who are you?\\
'''Finch:''' Who am I? I'm just like you, Mr. Barnett. A man who sold the world. Only I charged them $1.

-->'''Karen Page:''' Who sent you?
-->'''Matt Murdock:''' No one sent us.
* ''Series/TheDefenders2017'':
** Happens twice to [[Series/Daredevil2015 Matt Murdock]] in the course of "Mean Right Hook":
*** At the beginning of the episode, right after an artificial earthquake, Matt roofhops over from his apartment, still wearing suit and tie, and beats up some teenage looters as well as an overzealous store owner trying to shoot them with a shotgun. As Matt is catching his breath, one of the thieves utters a bewildered "Who ''are'' you?" before Matt walks away.
*** At the end of the episode, thanks to outsourced case work that Matt has received from Foggy, he finds himself walking into a police interrogation room to provide impromptu legal counsel to Series/JessicaJones2015 as she's being questioned by Detective Misty Knight.
-->'''Matt Murdock:''' [[DontAnswerThat Jessica Jones, stop talking.]] Hi. This is over.

-->'''Matt Murdock:''' My name is Matthew Murdock. I'm your attorney.
** Also from "Mean Right Hook," Series/LukeCage2016 and [[Series/IronFist2017 Danny Rand]] say this to each other as Luke interrupts Danny's attempt to rough up Cole for information.
** Danny gives a bewildered "Who are you people?" to Matt and Jessica as they're escaping Midland Circle in the elevator.
** At the Royal Dragon, Alexandra implicitly asks Luke who he is when Luke notes a contradiction between her words and the Hand's methods. Luke is smart enough to see where she's going.
-->'''Alexandra:''' I'm sorry, I don't believe we've been properly introduced.
-->'''Luke Cage:''' Let's keep it that way.

[[folder:Pro Wrestling]]
* Variant: Wrestling/TheRock would often act uninterested when being addressed by someone he viewed as inconsequential (which was pretty much everybody), waiting until they were finished before asking them, "Who in the blue hell are ''you''?", then interrupting them after a couple of syllables with, "IT DOESN'T MATTER WHAT YOUR NAME IS!"

'''[[PlayerCharacter Grayson Burrows]]:''': No, it's just got a load of cargo in the back, and a load of bills to pay at home.\\
'''Pirate:''' And I the same! You shouldn't kill me just for attacking you!\\
'''Burrows:''' I don't mind that you tried to kill me, but protecting myself against your kind gets to be expensive, and I'm on a budget! [missile to the pirate's face]

'''Optimus:''' Your worst nightmare!\\
''[Prime starts blowing away Megatron's army, single-handedly turning the tide]''
