What does it take to kill this guy? He's only human, right? [[TemptingFate Right]]?

Assumptions are dangerous. You assume that your foe is mortal and limited, that there are certain things they cannot do or [[NoOneCouldSurviveThat survive]]. When these assumptions break down, in their panic, many heroes or villains will ask, "What the hell are you?"

This panic can be triggered by the character having an unusual appearance or abilities, stunning the person who assumed they were normal and could be easily beaten.

* ''Anime/DragonBallZ'':
** Frieza has a moment after he realizes what a Super Saiyan is capable of. Frieza blasts Goku square in the face with one of his beams, sending his head reeling backwards. But Goku [[NoSell just slowly lowers his gaze back to normal]] [[TranquilFury like nothing happened]]. It's at that moment Frieza [[OhCrap realizes]] just what he's dealing with.
--->'''Frieza:''' You...you...''what are you''?!\\
'''Goku:''' I am the hope of the universe. I am the answer to all living things that cry out for peace. I am protector of the innocent, I am the light in the darkness. I am truth. ALLY TO GOOD! NIGHTMARE TO YOU!
** Vegeta has a similar moment in his fight with Cell. He's so drunk on his new-found power as an "Ascended Super Saiyan" that he lets Cell reach his Perfect form just so he'll have a worthy opponent. He doesn't realize this is a bad idea until Cell takes a full-power kick to the neck without even flinching.
--->'''Vegeta:''' What...''are'' you? I put everything I had into that attack. You should be dead!
** During Future Trunks' and Kogu's fight in ''Anime/DragonBallZBojackUnbound:''
--->'''Trunks:''' Whoa! What the hell are you?!
--->'''Kogu:''' Someone not to be trifled with, ''boy.''
** In the original series King Piccolo have this reaction after Goku survived a blast that nuked an entire city.

** In ''Resurrection 'F''', Vegeta asks this of Whis when Whis reveals that not only is he far more powerful than the freaking God of Destruction, but [[spoiler:he has the ability to ''reverse time''.]] Whis's response can be summed up as "I am me."
* The Strawhats got this a lot early in ''Manga/OnePiece'', both from whoever they're fighting and whoever happens to be watching.
* ''Manga/{{Naruto}}'':
** This is an equivalent of OhCrap, usually uttered when the speaker realizes he has just attacked a demon host.
** ''Naruto himself'' makes that exclamation of Pain when's he's impaled by his chakra rods. The rods are chanelled by Pain's own chakra, which allows him to mobilise his hosts - [[PeoplePuppets The Six Paths]], and disrupts Naruto's own once he stabs him with it. Ironically, in contrast to the above, Pain is fully aware he's going after a demon host and refers to Naruto as the demon inside him.
* Said (in the English dub at least) by Luke Valentine to Alucard in ''Manga/{{Hellsing}}''. Notably, this is coming from ''another vampire''. Alucard's just that CrazyAwesome.
-->'''Luke Valentine:''' What are you? ''WHAT IN THE HELL ARE YOU?!''
* Said once in ''Manga/{{Inuyasha}}'', surprisingly enough, to Kagome by [[VillainOfTheWeek Yura of]] [[CombatTentacles the Hair]]. Her confusion came from the fact that every time she swung a sword at Kagome, it bounced off of Inuyasha's kimono rather than slicing off her limbs.
-->'''Yura:''' What are you? ''Why don't you bleed''?
* In ''Anime/GingaDensetsuWeed'', Kamikiri and his dogs had nearly beaten Toube to death and leave his body there. But when Toube gets up, Kamikiri has a look of shock on his face, and he says this almost every word-for-word:
-->'''Kamikiri:''' What the hell is he?!?
* At the end of the first episode of ''LightNovel/{{Durarara}}'', the last human trafficker screams this when he runs down Celty, knocks off her helmet, and [[HeadlessHorseman notices she doesn't have a head]].
* Nanoha Takamachi of ''Franchise/LyricalNanoha'' has gotten this a couple of times, on account of basically being a human [[Franchise/{{Gundam}} Gundam]].
-->'''[[{{Cyborg}} Dieci]]:''' ''[after getting [[CurbStompBattle curb-stomped]] in a BeamOWar]'' Is she really human?
* Subverted in ''Anime/TheBigO'' in the first encounter between Alan Gabriel and R. Dorothy Wayneright (in which Gabriel is serving Ms. Waynewright with a NoHoldsBarredBeatdown):
-->'''R. Dorothy Wayneright:''' What exactly are you? A human? An android just like me? I'm unable to determine what you are.\\
'''Alan Gabriel:''' I'm the boogeyman!
** After the above exchange, Dorothy, who is ThreeLawsCompliant and couldn't have risked hurting a human, apparently concludes that Gabriel has just admitted to being non-human and [[CurbStompBattle ends him]].
* In ''Anime/YuGiOh'', after Bakura defeats Pegasus, he gloats that Pegasus didn't stand a chance against someone who has been playing Shadow Games for centuries. Terrified, Pegasus exclaims, "You've lived for ''centuries''!? What sort of creature are you!?" Bakura replies that he is someone destined to get all seven Millennium Items and rule the world.

* In ''Manga/{{Toriko}}'', after [[spoiler:Neo ''ate'' [[EarthShatteringKaboom a tiny supernova]], that Don Slime created as a last-ditch effort to [[TakingYouwithMe kill him along with himself and the rest of the planet]], Don]] suffers [[HeroicBSOD full-blown mental breakdown]] and asks, what the hell he is, while proclaiming, that creatures like this simply can't exist.
** Happens again (although on a smaller scale) in the very next chapter. This time [[spoiler:NEWS]] asks [[spoiler:Jiro]] what he is, not believing that human (or really any Earth creature besides Eight Kings) can withstand his attack without injuries. In response to questions about the origin of his powers, [[spoiler:Jiro]] reveals that he [[spoiler:was [[RaisedByWolves raised by the Wolf King]], who would feed him [[HumanoidAbomination Red]] [[TheDreaded Nitros]] since he was a baby.]]
--->'''[[spoiler:NEWS]]:''' That attack rocked the very planet's mantle... and he still stopped it?![[spoiler:Jiro]]!! What the hell are you?!\\

-->'''Lucio:''' What are you?\\
'''Hive:''' What are '''we'''. ''[[[HiveMind infects him with spores]]]''
* ''Series/BuffyTheVampireSlayer'':
** When Riley Finn discovers the little blonde college girl he's dating is a DemonSlayer with SuperStrength and HealingFactor, his first question (once he has a chance to ask one) is "What [[[WhoAreYou not who]]] are you?" Buffy, picking up the WhatMeasureIsANonHuman subtext, is not amused.
--->'''Buffy:''' [[SarcasmMode Capricorn on the cusp of Aquarius]]. And you?
** Mild version -- in Ms. Calendar's first episode, Giles finds she's aware and knowledgeable of supernatural forces, so he asks, "You don't seem particularly surprised by... who ''are'' you?"
* ''Series/TheCrowStairwayToHeaven'' episode "Solitude's Revenge":
-->'''Kessler:''' What the hell are you?\\
'''The Crow:''' Death without parole.
* ''Series/DoctorWho'':
** Played for laughs in [[Recap/DoctorWhoS30E7TheUnicornAndTheWasp "The Unicorn and the Wasp"]]. The Doctor is fatally poisoned with cyanide, but survives by scarfing down various ingredients and then giving his system a shock -- at which point he exhales the poison as a cloud of smoke. Creator/AgathaChristie, who sees the whole thing, is naturally stunned.
-->'''Agatha:''' Doctor. You are ''impossible.''\\
'''The Doctor:''' ''[clicks teeth, runs off]''\\
'''Agatha:''' What are you?!
** In [[Recap/DoctorWhoS30E11TurnLeft "Turn Left"]], Donna Noble is suckered into rewriting part of her life. The ensuing alternate universe is already overkill, but it ends up nearly destroying the whole universe before Donna (with help from Rose) undoes it all. The fortune teller who did it freaks out and uses this trope.
-->"You were so strong. What are you? What will you be? What will you be?!"
** The Doctor meets a woman named Oswin Oswald in a [[Recap/DoctorWhoS33E1AsylumOfTheDaleks Dalek asylum]] in the far future, and she dies. Then he meets the same woman (now named Clara) in [[Recap/DoctorWho2012CSTheSnowmen Victorian London]], and she dies. Baffled as to how this could have happened, he seeks her out and encounters ''another'' incarnation of her in [[Recap/DoctorWhoS33E6TheBellsOfSaintJohn modern times]], and adopts her as his new companion to figure this out. He avoids confronting her directly about this until [[Recap/DoctorWhoS33E10JourneyToTheCentreOfTheTARDIS several adventures in]], when it seems they are both going to die. He demands to know just what the hell she actually is, but Clara is just a normal woman and has no idea what he's talking about. It later turns out that [[spoiler:this Clara ''is'' a normal woman, and the ''original''; she winds up entering the Doctor's personal timeline in order to thwart a villain who had done the same, causing multiple incarnations of her to appear throughout his life.]]
* ''Series/{{Smallville}}'' is rife with this. Clark gets this all the time, but more commonly "how did you do that?" as he is completely unafraid of using his powers in plain sight of villains. There are at least two examples directed towards other characters:
** "Arctic": Brainiac thinks Chloe Sullivan is a normal human. When he pierces her head with his finger tendrils, she unleashes her healing powers in defense, weakening him to the point where he had difficultly burning through a fence with his heat vision. One of the very rare, if not the only, instances in which you see him staggering and panting.
--->'''Brainiac:''' What the hell are you?
** "Phantom": Bizarro has just been rejuvenated from kryptonite instead of harmed, and knocks Lionel Luthor against a wall.
--->'''Clark Kent:''' What the hell are you?\\
'''Bizarro:''' I'm you, only a little more bizarre.
* ''Series/{{Supernatural}}'':
** When Dean first meets [[OurAngelsAreDifferent Castiel]], he assumes Castiel is a demon. Then the angel [[NoSell shrugs off the demon-killing knife]], prompting this exchange:
-->'''Dean:''' Who are you?\\
'''Castiel:''' [[MathematiciansAnswer Castiel]].\\
'''Dean:''' Yeah, I figured that much, I mean what are you?
** In the tenth season episode, "Reichenbach", a man named Cole tries to kill Dean to avenge his father who Dean killed ten years earlier (Cole was unaware that his father was a monster). Unfortunately for Cole, Dean is [[spoiler: a [[FaceHeelTurn demon]] at this point in time]] and [[CurbStompBattle brutally beats Cole]] in response.
-->'''Dean:''' You have no idea what you walked into here, do you? None.\\
'''Cole:''' What are you?\\
'''Dean:''' [[spoiler: I'm a demon. ''[[[BlackEyesOfEvil Dean's eyes turn black]]]'']]

* In ''Theatre/PeerGynt'', Peer finds an {{Invisible Monster|s}} that blocks his path while refusing to provide a straight answer to the question, "Who are you?" When Peer changes the question from "who" to "what", it replies coherently. In a sense:
-->'''Peer:''' Stuff that stupid answer, it doesn't make things clearer. ''What'' are you?\\
'''Boyg:''' The Great Boyg.\\
'''Peer:''' Ah. Until now, the riddle was black, now it seems grey...

[[folder:Video Games]]
* ''VideoGame/TombRaiderUnderworld'':
-->'''Lara Croft:''' Tell me this: what the hell are you?\\
'''Lara's Doppelganger:''' I am you with the flaws removed!
* VideoGame/BatmanArkhamSeries:
** In ''[[VideoGame/BatmanArkhamAsylum Arkham Asylum]]'', Scarecrow asks this of Batman after he has had ten times the normal dose of fear gas and is still alive and sane.
** In ''[[VideoGame/BatmanArkhamCity Arkham City]]'', terrified mooks will demands this of Franchise/{{Batman}}, ComicBook/{{Robin}}, and/or ComicBook/{{Nightwing}} after their mook buddies begin dropping like flies during [[StealthExpert Predator]] mode.
** ''[[VideoGame/BatmanArkhamOrigins Arkham Origins]]'' repeats this trend with Deathstroke. Given that the world's greatest assassin has just had his ass kicked by a previously unknown vigilante dressed like a flying rodent, his shock is more or less validated. Copperhead also has a similar reaction when Batman, [[ImplacableMan despite having been poisoned by her, continues to fight on]].
* From ''VideoGame/{{StarCraft|I}}'', Zeratul to Duran: "Who...what are you?"
** ''VideoGame/StarcraftII'' expansion has everyone wondering just what the hell Kerrigan is. She was [[spoiler:de-infested at the end of ''Wings of Liberty'', and seems to have little-to-no memory of the time she spent infested, yet still can control the swarm and still has Zerg features about her.]] Is she really redeemed this time, or is she just trying to pull her MagnificentBastard act again?
* ''VideoGame/CaveStory'': After [[RecurringBoss the second fight against Balrog]], as Balrog is retreating:
-->'''Balrog:''' What ARE you?\\
'''Player character:''' [[HeroicMime ...]]
* In ''VisualNovel/{{Danganronpa}}'', [[spoiler:Junko Enoshima]] has this reaction after Makoto is able to bring hope to the remaining surviving Ultimate students and the BigBad can't deal with how he [[spoiler:eventually was christened as the Ultimate Hope, which was the opposite to Junko's Ultimate Despair title]].
* ''Franchise/DevilMayCry'':
** This exchange in ''DMC 3'', after Dante beats [[WakeUpCallBoss Cerberus]] (paraphrased from memory):
--->'''Cerberus:''' You're not human, are you?\\
'''Dante:''' Who knows? To tell you the truth, I'm not even sure myself!
** And again in ''DMC 4'':
--->'''Berial:''' Your [[RedRightHand arm]]... [[OhCrap you're not human!]]\\
'''Nero:''' [[NoodleIncident Don't ask.]] [[CursedWithAwesome Damn thing drives me crazy, though.]]
** Also happens in the first game:
--->'''Phantom:''' You, you're not just any ordinary human. What are you?\\
''[Dante says nothing, but Phantom briefly sees an image of Sparda in Dante's place]''\\
'''Phantom:''' [[OhCrap The legendary Sparda!?]] [[ThisCannotBe It can't be...]]\\
'''Dante:''' Close. I'm his son!

-->'''Firion:''' You make me shiver... What are you!?
* In ''VideoGame/HeroesOfMightAndMagic V'', Nicolai asks this of Agrael when the demon lord resists the power of Nicolai's Amulet [[spoiler:that has the power to send demons back to Sheogh]]. This is the first hint that Agrael [[spoiler:isn't actually a demon. He's really a Dark Elf.]]
* ''Franchise/MassEffect'':
** After Commander Shepard defeated Sovereign, it's implied that part of the reason the [[EldritchAbomination Reapers]] turned their attention to Humanity is due to desperately trying to understand how [[HumansAreAverage an average species]] with no special mental or physical attributes, somehow managed to produce a ''single'' individual who is [[TheDreaded so incredibly disruptive to their plans.]]
** In the ''Leviathan'' {{DLC}}, [[spoiler: even the ''[[EldritchAbomination Leviathan]]'' have this reaction to Shepard, referring to them as "An Anomaly" that has never manifested before in any previous Cycle. They too are ''very'' curious why Shepard is the first thing that the Reapers have ever shown ''fear'' towards.]]
--->'''[[spoiler: Leviathan]]:''' [[spoiler: None have possessed the strength in [[YouCantFightFate previous Cycles]]. Your own species could be destroyed with a [[PunyEarthlings single thought]]. But ''[[TheChosenOne you]]'' are different. I have witnessed your actions in this Cycle: the [[DidYouJustPunchOutCthulhu destruction of Sovereign]]; the [[AllYourBaseAreBelongToUs fall of the Collectors]]. The Reapers perceive [[WorthyOpponent you]] as [[TheDreaded a threat]]. And I ''must'' understand '''why!''']]
* ''VideoGame/DragonAgeII'':
** Knight-Commander Meredith has this reaction towards a Mage!Hawke for taking down the Arishok in honourable single-combat, which leads to the rest of the Qunari peacefully leaving and ends the siege of Kirkwall without further incident.
** Fenris will also act this way towards Flemeth, remarking that he has met abominations, demons, and blood mages before, and Flemeth is none of those things. Anders is similarly perturbed that even ''Justice'' doesn't know what she is!
* A non-villainous example in ''[[VideoGame/PokemonMysteryDungeonExplorers Pokemon Mystery Dungeon: Explorers of Sky]]'': in the BonusEpisode detailing [[TheDitz Wiggly]][[BigGood tuff's]] origins, as an Igglybuff, he was taken under the wing of a local recluse and former explorer Armaldo. As the two progress through one particular dungeon, Armaldo points out all the traps in the area, including the [[PitTrap concealed pit]], [[TheWallsAreClosingIn spiked walls]], and numerous other traps waiting to deter hopeful explorers. Igglybuff ignores all this, and just uses his unknown power to ''break the door down''. This leaves Armaldo wondering:
-->'''Armaldo:''' What in the world IS this kid?!
* In ''VideoGame/TheLegendOfZeldaSkywardSword'', Ghirahim is outraged that Link actually managed to beat him. This doesn't deter him from taunting Link, though.
-->'''Ghirahim:''' [[VillainousBreakdown This... This is preposterous. Driven to my knees by a simple child of man? Laughable! No matter how many times we clash, I can't prevail! You think I can't defeat you? You think I can't win?!]] Boy... what ''are'' you?
* ''VideoGame/MetalGearRisingRevengeance:'' When [[CorruptPolitician Senator Armstrong]] steps up to the plate and reveals his full power, both Raiden and Jetstream Sam ask him this word-for-word.
* ''VideoGame/MarkOfTheNinja'': When the player character terrorizes the {{Mook}} guards, one of things they'll mutter as they stumble backwards is "What ''is'' this guy...?"
* ''VideoGame/Persona4'' has Yosuke saying this line after his attempt to unmask Teddie shows there's nothing inside.
* ''VideoGame/EternalDarkness'': A cutscene combines it with GlamourFailure when the "liche" Pius Augustus posing as a warlord confronts a defeated enemy.
-->'''Soldier:''' Who are you?\\
'''Pius Augustus:''' I am your lord and conqueror!\\
'''Soldier:''' What manner of forsaken being are you?\\
'''Pius Augustus:''' ''[shifts to his skeletal form]'' So, you can see me in my true form...
* ''VideoGame/KingdomHeartsChainOfMemories'':
** After Zexion barely escapes from Riku, he screams, "What is he? No-one's ever worn the darkness the way he does. It's impossible!"
** After Vexen fades away to nothingness upon his death, Sora can only respond with this to the remaining members of the Organization. Not even Axel -- the Organization member who killed Vexen -- can give him an honest answer.
* ''VideoGame/FinalFantasyXIV'' has the final boss of Heavensward ask this of the player character. [[spoiler: Archbishop Thorden, who became a primal via using an ArtifactOfDoom and a millenia of prayers, is defeated by the player and he becomes absolutely terrified of them since he was (possibly) the strongest primal to date and was beaten by someone who doesn't have the same kind of power.]]
* Shadow asks this of Sonic in ''VideoGame/SonicAdventure2'' after the eponymous blue hedgehog survives being [[spoiler:''ejected into space.'']] Though in this case it's out of genuine curiosity rather than panic.
* In ''VideoGame/Fallout4'' the Sole Survivor can ask Nick Valentine this after the former rescues him due to his being a synth missing the rubber skin. This is probably because the synths the Sole Survivor may have encountered thus far are [[KillerRobot Killer Robots]] unlike the robot-bodied, human-acting Nick.
-->'''Sole Survivor:''' Just...what are you, Nick?\\
'''Nick:''' You really don't know? I'm a synth. Synthetic man. All the parts, [[DeadpanSnarker minus a few red blood cells]].
* In the beginning of ''VideoGame/{{Rosenkreuzstilette}} Grollschwert'', Grolla has happened to overhear [[spoiler:Iris' plans to have RKS fight against the Empire for her own twisted amusement]]. Immediately afterwards, [[spoiler:Iris]], followed by an OhCrap moment of [[spoiler:hers]] that she recovers from quickly followed by Grolla's YoureInsane lecture towards [[spoiler:her]], attacks her with [[spoiler:her magic]], which critically wounds her and takes her by surprise. Shocked by the fact that [[spoiler:Iris had such powerful magic]], Grolla, in an injured, shaken tone, asks [[spoiler:her]] just what the hell [[spoiler:she]] is.
-->[[spoiler:'''Iris''']]: Oh, what a bother. I suppose I'll have to start the show early and kill you now! (attacks and severely wounds Grolla with her magic)\\
'''Grolla''': What in the...!? How did she obtain such powerful magic? [[spoiler:Iris]], what ARE you!?\\
[[spoiler:'''Iris''']]: Heheheh. Why, I am myself, of course. I don't expect a commoner to understand my genius.

* In the Sonic fan animation ''WebAnimation/NazoUnleashed'', much like the example with Vegeta and Cell (which it draws inspiration from) Shadow quips this to Nazo after his ultimate attack fails to even scratch him.
-->'''Shadow:''' Just... who are you!?!\\
'''Nazo:''' '' I'm '' the Ultimate Lifeform!
* In the alternate ending for the ''WebVideo/SuperPowerBeatDown'' with Franchise/{{Batman}} vs. [[Franchise/StarWars Darth Vader]], the former manages to best the latter not through science or by fighting like a CombatPragmatist but by planning ahead and using all the tools at his disposal, including [[spoiler:Franchise/{{Superman}}, the one he came to rescue in the first place]]. Even the Sith Lord has to wonder how a seemingly ordinary human managed to overcome his Force advantage.
-->'''Darth Vader:''' ''[wheezing]'' What are you?\\
'''Batman:''' ...I'm Batman.

* In ''WesternAnimation/BatmanBeyond'', when Batman meets Spellbinder for the first time, he's shocked by Spellbinder's unusual appearance (he wears an orange suit that seamlessly covers his entire body, [[TheBlank even his face]]) and asks, "What the heck are you!?"
* In ''WesternAnimation/JackieChanAdventures'', the title hero makes this question in the 1st season's finale to the released [[OurDemonsAreDifferent Shendu]], who answers with an IAmTheNoun BadassBoast.
-->'''Jackie:''' Who... ''What'' are you?!\\
'''Shendu:''' I ''am'' the keeper of the Talismans. I ''am'' the apocalypse of which legend speaks! And I ''am'', for once and for all, your executioner!
* From ''WesternAnimation/TheLegendOfKorra'': [[BigBadWannabe Tarrlok]] asks this of [[BigBad Amon]] after he [[spoiler: powers through Tarrlok's bloodbending, a technique that has rendered two different Avatars helpless]]. The answer he gets is "[[CreepyMonotone I am]] [[IAmTheNoun the solution.]]" [[spoiler:He's actually Tarrlok's older brother Noatak, an ''even more powerful'' Bloodbender.]]
* ''WesternAnimation/LooneyTunes'': Zig-zag -- the Devil himself asks Yosemite Sam "Who the hell are you?" when he lands in Hell in the cartoon "Satan's Waitin'".
* ''WesternAnimation/StarWarsRebels'': In [[Recap/StarWarsRebelsS3E20ZeroHourPartII "Zero Hour"]], Thrawn and his Death Troopers approach the wounded Bendu.
-->'''Thrawn:''' What manner of creature are you?\\
'''The Bendu:''' [[BadassBoast One beyond your power to destroy]].
* In ''WesternAnimation/TeenTitans'', Robin asks "What are you?" to Slade when [[spoiler:Slade's mask comes off to reveal a SkullForAHead.]]
