[[caption-width-right:309:Looks like he [[DidntThinkThisThrough didn't think his plan through.]]]]

* Generally, most 'Toons get this look right before [[GravityIsAHarshMistress gravity takes a hold of them]].
* ''WesternAnimation/AdventuresOfTheGalaxyRangers'':
** The other three Rangers have busted into the Queen's [[SupervillainLair Asteroid Palace]] (which they've done before) to rescue their captain. Around the corner comes a Slaverlord, a high-end class of {{Mook|s}} they've shot down dozens of times before...Guns up, they're about to open fire. The Slaverlord's form then takes on Zach's form [[MassOhCrap and they realize they didn't get there in time]].
** Another good one was in "Aces and Apes." The Rangers are chasing Lazarus Slade, who is a marginally competent member of their RoguesGallery...but then they see that Slade has a partner. Said partner is The Scarecrow, arguably their ''nastiest'' opponent.
* In ''WesternAnimation/AladdinTheSeries'' / ''[[WesternAnimation/{{Hercules}} Hercules: The Animated Series]]'' crossover, Aladdin gets two good ones -- once when [[PunchPunchPunchUhOh he tries swing-kicking Herc off Pegasus to no effect]], and then later when he realizes he and Herc have made a big mistake fighting each other.
* ''WesternAnimation/AmericanDad''
** Stan when he finds out that Jeff broke up with Hayley. [[TeensAreMonsters He has every right to be afraid.]]
--->'''Francine:''' Stan, Hayley and Jeff broke up.\\
'''Stan:''' So, she breaks up with Jeff at least every other week.\\
'''Francine:''' You don't understand! This time, ''he'' broke up with ''her!''\\
'''Stan:''' ''(cue DramaticDrop)''
** Also when he forgot his and Francine's anniversary, considering [[NoHoldsBarredBeatdown what happened last time.]]
** Francine and Hayley can also get pretty creeped out by Stan themselves. They pull this off when realise how [[SmallNameBigEgo Stan]] [[SanitySlippage reacts to criticism]].
--->'''Klaus:''' [[GratuitousGerman Oh mein Gott]]. He has heard everything!
* The last episode in season 1 of ''WesternAnimation/AmericanDragonJakeLong''. The entire huntsclan makes this face when huntsgirl uses magic skulls to wish that [[spoiler: every member of the clan would die.]]
* ''WesternAnimation/{{Animaniacs}}'' has several:
** In "The Big Candy Store", [[{{Jerkass}} Mr. Flaxseed]] has one before the Fighting Irish beat him to a pulp.
** In "Bumbie's Mom," after Slappy Squirrel has cheered Skippy up from the trauma of ''[[Disney/{{Bambi}} Bumbie]]'', on the plane ride home they watch the in-flight movie, which turns out to be ''[[Literature/OldYeller Old Yellow]]''. Slappy gives the "Oh Crap!" face when we hear the titular dog being shot, leading to a HereWeGoAgain ending (with Slappy flatly commenting "[[ThisIsGonnaSuck Uh-oh]].")
* During the finale of ''WesternAnimation/AvatarTheLastAirbender'', [[spoiler:[[strike:Fire Lord]] Phoenix King Ozai]] goes into serious Oh Crap mode when [[spoiler:Aang enters the Avatar State during the final showdown]], especially after he sees, [[http://img1.wikia.nocookie.net/__cb20130601101720/avatar/images/d/d3/Elemental_tornado.png this]]. [[CurbStompBattle The asskicking that ensues is nothing less than epic,]] and starts with [[spoiler:grabbing him by the beard and blasting him into a stone pillar]].
** [[spoiler:Ozai]] gets a somewhat more subdued Oh Crap expression earlier in the same fight, when [[spoiler:Aang catches his massive Comet-enhanced lightning attack and looks like he's going to redirect it right at Ozai, who unlike Aang had no way to defend against lightning. But since Aang [[ThouShaltNotKill refused to kill, he redirected the lightning into the sky instead.]] Something in Ozai's smirk immediately afterwards gives the impression that he had expected that…but he still doesn't try using lightning again]].
** Jet gets a slow-motion zoom-in shot of this nature when [[spoiler:Long Feng kills him]].
** This is Aang's reaction when he just barely manages to save himself from getting skewered with a throwing star in his first battle with Mai.
** Sokka also gets several, one notable example of which is his expression in Episode 2, when the Fire Nation boat is about to mow him down.
** The look on Zuko's face when he realizes that his sister is about to wipe the floor with him at the start of Book 2 really says it all.
*** Also in the Book 1 episode "The Storm". During a flashback, younger Zuko does this when he realizes that his own father is about to burn the [[{{Pun}} royal crap]] out of him.
*** Actually, Zuko gets a lot of these... practically once an episode during Book 1.
*** One particularly epic one came in chapter 18 when Zhao [[spoiler: sees and recognizes the swords used by the Blue Spirit (Zuko) when he freed Aang from the Fire Nation fortress]]. Zuko instantly realizes that Zhao just put two and two together and the look on his face just ''screams'' this trope.
** In the ''Day Of Black Sun'', we get a close-up of Aang's face panning [[http://piandao.org/screencaps/ep51/ep51-540.png out]] to reveal an equally shocked Sokka.
*** The characters and viewers get one towards the end of that two-parter with the reveal not only that the Mechanist's air balloon had been mass-produced by the Fire Nation, but that they'd gone and invented ''airships''.
** Zhao [[spoiler: when La grabs him.]] That is all.
*** A little bit before then, Zhao realizes he's in deep shit when [[spoiler: he kills Tui]], and Iroh retaliates.
** Azula herself gets one in the GrandFinale... when [[spoiler: Katara encases her in a block of ice]].
** Katara gets one of these towards the end of Season 2, when she discovers Zuko in Ba Sing Se, goes to the palace to report him, and [[spoiler: there runs into Azula and company disguised as the Kyoshi Warriors]]. Not your lucky day, Katara.
** After taking down a bunch of Fire Navy ships at the North Pole, Aang looks out a bit farther to sea and realizes he still has a few ''hundred'' left to go...
** Crowning one goes to the opening of season 2, where Azula and her elite guard almost tricked Zuko and Iroh onto the Fire Nation boat. When the captain uttered "we're taking the prisoners home", not only does he get an Oh Crap face, but so does Azula, Iroh and Zuko. 4 for the price of 1!
*** Iroh doesn't really give an OhCrap face as he suspected this kind of treachery. His face was more of a "Time to kick ass" face.
*** And Azula's wasn't really an OhCrap face either. It was more of a "[[YouHaveFailedMe you idiot!]]" face, as she was looking directly at the captain.
** The Earthbender general in "The Avatar State" gets one when he realizes that Aang in the Avatar State is not too happy with him.
** One more for Azula (as the show's resident MagnificentBastard, she doesn't get too many herself), during the season two finale when Aang collapses the rock formation she's clinging to. Particularly notable as the only time we ever hear her ''gasp in fear''.
** [[spoiler: Hama]] gets two moments in The Puppetmaster; once when Katara breaks free from her control, and again just before Katara floors her with a powerful waterbending attack.
** From the first season, the episode that introduces Hei Bai has two, both involving Roku's dragon. The first, of course, is when Aang sees the dragon heading towards him, and realizes that he ''can't bend in the Spirit World,'' and the second is when the dragon ''banks up and flies towards the ceiling'' in Roku's temple. Seeing that the dragon never did intend to hurt him, though, each of these instances would probably count more as a [[SubvertedTrope subversion.]]
** When the sandbenders [[spoiler: steal Appa]] and Aang finds out, it's too late for them to do anything about it. Aang gets GlowingEyesOfDoom, and the sandbenders realize that they are facing a PhysicalGod who is ''insanely'' ticked. Sure, Aang cools down before any real damage is done...but even Sokka and Toph were running away scared.
** Oh man, when [[SealedGoodInACan Avatar Roku]] manifests before the traitorous fire Temple Sages, he ain't happy about the way they've been treating his reincarnated self. The poor sages don't even stop to think, no - they just shit their pants and '''[[DontAskJustRun RUN.]]'''
** Long Feng has one when Azula gives him a [[BreakThemByTalking Breaking Speech]] and turns his own men against him, as he realizes too late that this teenage girl he thought was in over her head ([[ObfuscatingStupidity an idea that she helped fuel]]), was in reality [[MagnificentBastard the most cunning and dangerous player in the game.]]
* ''WesternAnimation/TheAvengersEarthsMightiestHeroes'':
** D-list bad guy the Mandrill gets a great example of this during the beginning of episode 3. After robbing a bank he is confronted by...the Wasp. He's less than impressed. Then Iron Man shows up. Still confident. Then Thor, Giant-Man, and ''the Hulk'' show up. His spectacular oh crap face is followed by a wise choice to surrender.
** Another great example comes when the Avengers must stop Kang from taking over New York. When Hawkeye and Hulk encounter some of Kang's robots on a bridge, Hawkeye tells the Hulk to go rest while he fights them solo. The robots then [[spoiler: combine into one GiantMecha]], leaving Hawkeye shocked.
--->'''Hulk:''' [[ScrewThisImOuttaHere Maybe I will rest now.]] ''(starts walking away)'' Good luck. ''(Mecha blasts him InTheBack)''
** Five Avengers react like this after Ultron's beam apparently causes [[spoiler: Thor to vanish]].
* Used by heroes and villains alike at various points in ''WesternAnimation/BarbieAndTheDiamondCastle'', but VainSorceress Lydia ends up with one of these looks permanently etched on her face when she's [[KarmicDeath turned to stone]].
* ''WesternAnimation/BeastWars'':
** "Power Surge": [[TheStarscream Terrorsaur]] has lost his stash of SuperEmpowering energon and made his way back to the Predacon base:
--->'''Terrorsaur:''' Blast those Maximals! They destroyed my power! But at least I got rid of Megatron.\\
'''Megatron:''' Well, well, look... who's... back!\\
'''Terrorsaur:''' ''(tiny voice)'' Help!
** In "Other Voices Part 1", Optimus Primal has been captured by the Vok and scanned (which is incredibly painful). After recovering somewhat, Optimus opens his eyes... and nearly shits himself when he sees the head of '''Unicron''' staring down at him. He calms down when the Vok explain that they looked into his memories and are using AFormYouAreComfortableWith.
* Happened to Butt-head in ''WesternAnimation/BeavisAndButtHead'''s Butt-O-Ween special. But, being Butt-head, his facial expression remains static, and his reaction amounts to "Uhh, uh-oh."
* In the ''WesternAnimation/{{Ben 10}}'' episode "Ben 10,000 Returns", when [[spoiler: young Ben as Waybig is hit by Eon's time aging ray and crumbles into a big pile of dust, Professor Paradox and Ben 10,000 both give a great open-mouthed oh crap face from a side view]].
* In the ''WesternAnimation/ChipNDaleRescueRangers'' episode "Seer No Evil", Monterrey Jack has one when he realizes that he, Gadget, and Dale are in a trunk, which is the last of the fortune teller's predictions that ends with Chip's death. [[spoiler: He doesn't die after all.]]
* ''WesternAnimation/{{Chowder}}'': In "The Party Cruise", Mung Daal offers to tell Chowder one of his fishing stories.
-->'''Mung Daal:''' Did I ever tell you the story of my famous one-thousand-day fishing trip?\\
'''Chowder:''' ''How'' many days?\\
'''Mung Daal:''' A thousand.\\
'''Chowder:''' ''Oh gosh...''
* Mostly everyone in ''WesternAnimation/CodeLyoko'' will experience ''something'' that would result into "Oh, crap" faces. This mostly happens with XANA attacks, but rarely will it be because of something they did.
** Yumi pulls this face when she realizes Jeremie's notes are as big as ''Literature/WarAndPeace''.
** Ulrich pulls this reaction when Jeremie tells him that the batteries on his robot died.
* Towards the end of TheMovie of ''WesternAnimation/CodenameKidsNextDoor'', the BigBad is bragging about how nothing can stop him.
-->'''Grandfather:''' Not even a... ''(looks up)'' [[ColonyDrop gi-huge-ic flaming moonbase]]? ''(cue Oh Crap face)''
** Of course, it turns out he was right but it still counts.
* WesternAnimation/CountDuckula has one of these at the start of each episode in the ExpositoryThemeTune. Igor really should have checked the label first...
* ''WesternAnimation/DannyPhantom'':
** [[FanNickname Dan Phantom]] gets one in the episode "The Ultimate Enemy", when he's sent flying into a petrol tanker [[spoiler: and quickly learns one of the drawbacks of having FlamingHair, as the vehicle explodes]].
** In "Memory Blank", Danny himself gets one when he realizes that when Sam wished she never met him with Desiree is around to hear it.
* ''WesternAnimation/DarkwingDuck'': This reaction usually followed the mighty midnight mallard's confident heroic banter right before he got pummeled. It never lasts long; in mere seconds, he's back to scheming and scrambling for the means to thwart evil.
** "Life, the Negaverse, and Everything": Darkwing has this reaction when Megavolt rallies Bushroot, Quackerjack, and the Liquidator to prove to Negaduck that they're not losers, seconds before the four villains rush the unfortunate vigilante.
** "Dry Hard": Darkwing gets a quiet freaked-out reaction when he realizes that the water in the vat Fludd fell into has dissolved the stick he was trying to use to retrieve him.
** "Darkwing Dubloon": Megavolt gets this expression on his face after Darkwing magnetises him and he finally contorts his body to avoid being impaled by the flying cutlasses of his crewmates - only to see a cannon skidding across the deck toward him...
** "[[Recap/DarkwingDuckS1E48LikeInBlunt Like in Blunt]]" includes a non-combat example of dismay when Darkwing realizes (at the end of the episode) that he and Blunt left Launchpad in the DeathTrap when they escaped.
* The Franchise/DCAnimatedUniverse is fond of the "Oh, no" variant, and manages to keep it consistently funny, at that.
** The greatest example possibly comes in ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'', when the time-traveling villain Chronos sends one of the Jokerz back to the time of the dinosaurs for betraying him:
--->'''Chucko:''' Hah! You think I'm scared? I'll be ''running'' this dump in a few ye-- ''(looks up; sees [[ColonyDrop comet coming right at him]])'' Aw, ''[[GoshDangItToHeck phooey]]''.
** From "Hereafter":
---->'''Kalibak:''' I just flattened Wonder Woman! You really think you can beat me?\\
'''Batman:''' [[MyDefenseNeedNotProtectMeForever I'm not trying]] to ''beat'' you. I'm trying to ''stall'' you.\\
'''Kalibak:''' Stall me? For what? ''(turns to see Superman behind him)'' Aw-- ''(punched in the face)''
** At the very end of "Secret Society", we are treated to a gorilla's OhCrap face after Grodd attempts to use his psychic attack on Superman, who manages to resist enough to [[FingerPokeOfDoom flick Grodd in the nose, sending him flying]]. A little earlier, Shade had one on as Superman, in the blink of an eye, interposed between his fist and Batman.
** There's a pretty priceless one early on when ComicBook/LexLuthor is informed that while humans are mostly unaffected by Kryptonite, studies have shown that it can cause blood poisoning in terrestrial life if the subject is exposed for a long period of time. Lex happens to carry some around in his pocket.
** Luthor tops himself in the episode "Alive!", part 1 of the series finale. His change of expression from exultant triumph to shock and horror when [[spoiler:he resurrects ''Darkseid'' instead of Brainiac]] is just epic.
** Luthor has another classic moment of dismay after AMAZO copies ComicBook/MartianManhunter's abilities (which include {{telepathy}}) and tells Luthor, "So, you ''lied'' to me...".
** At the end of the episode "This Little Piggy", when ComicBook/{{Zatanna}} is magically tossing things at Circe:
--->'''Circe:''' Insolent trickster! You dare to strike... ''(smacked with a chair)'' You dare to strike... ''(smacked with a table)'' [[RuleOfThree You dare to strike...]] ''(covered in a tablecloth, yanks it off)'' QUIT IT! [[OhCrap Oh, no...]] '''''(hit by a piano)'''''
** In the episode "Ultimatum", Giganta gets Bizarro to distract Wonder Woman while she goes to free Grodd. On her way to his cell she runs into a tiny Long Shadow blocking her way:
--->'''Giganta:''' Out of the way, tiny.
--->'''Long Shadow:'''''(grows until he becomes a full head taller than her)'' You were saying?
--->'''Giganta:''' Oh, poop.
** A brief one from the first part of the above-mentioned Chronos episode: Green Lantern and Batman are sitting in the cafeteria discussing their respective love lives; Batman is explaining that Wonder Woman [[SheIsNotMyGirlfriend is not his girlfriend]].
---> '''Batman:''' Diana's a remarkable woman, she's a valued friend. She's...
---> ''(Lantern gives him a look; Batman notices)''
---> '''Batman:''' ''(eyes slightly wide)'' ...standing RightBehindMe, isn't she?
---> '''Wonder Woman:''' Don't let that stop you... [[DiggingYourselfDeeper keep digging]].
** From the ''JLU'' episode "Grudge Match". Hawkgirl, Vixen, Black Canary and Huntress, four of the toughest women in the League, have just shrugged off the mind control forcing them to fight each other. They stand ready to face the villain...who brings out a mind-controlled Franchise/WonderWoman. Four to one odds and they're still in big trouble.
---> '''Vixen:''' Anyone got a plan?
---> '''Hawkgirl:''' Yeah. [[TryNotToDie Try to stay alive]].
---> '''Huntress:''' Anybody got a ''good'' plan?
** This one takes most of the episode "Far From Home" to set up. Supergirl, Green Arrow, and Green Lantern are abducted to the 31th Century by Brainiac 5, who is nearly clobbered by Supergirl before he can explain that he's a ''good'' guy, unlike that OTHER Brainiac. The two eventually hit it off. \\
In the last scene, GA and GL are back in the present, and show Superman a farewell video from Supergirl: she's staying in the future because it's more like her lost home, and "Also, I met this boy...." It's a heartwarming moment as Superman realizes that although this is the best for her, he may never see his young cousin again.\\
Then, smirking a little, he turns to the heroes:
---> '''Superman:''' Now, this boy Kara likes so much -- does he have a name?
---> '''Green Lantern and Green Arrow''': ([[Funny/JusticeLeague Priceless facial expression, then fade to black]].)
** GA and his ex-sidek--err, ''partner'', Speedy, get one when their [[DangerousForbiddenTechnique Quantum Arrows]] hit super-soldier Eiling in the chest, cause a colossal explosion, and...[[NoSell don't even faze him]]. Their eyes, masks and all, show the fear that [[CasualDangerDialogue their voices don't]].
---> '''Speedy:''' We are ''so'' dead.
---> '''Green Arrow:''' Could be.
** Then there was the time one member of a bunch of Green Lanterns sees what's coming and only gets out the "Oh" before they're ''incinerated in a moment.''
** "[[Recap/JusticeLeagueUnlimitedS2E4TaskForceX Task Force X]]": BadassNormal supervillain Plastique has three moments like this, like being asked what will she do if facing Superman, seeing [[UncomfortableElevatorMoment Green Lantern use her elevator]] or [[RightBehindMe hearing Captain Atom chastise her unladylike manners]].
* ''WesternAnimation/BatmanTheAnimatedSeries''
** In "The Laughing Fish": ComicBook/TheJoker jumps into the ocean, completely forgetting about the shark that had recently been released
-->'''Joker:''' See, Batsy, I think of everything! Hahahahahahaha-- AAAAAAAAAAAAHHHHHH!
** "Almost Got 'Im":
*** Several villains have been sitting around playing poker and sharing stories about how they almost killed Batman, but failed. The Joker's story ends with him successfully capturing Catwoman and he reveals her location, and that he's about to head off and finish her. Then Killer Croc says "I don't think so" in Batman's voice, and the Joker's expression in the split second before he's thrown across the room is priceless.
*** Harley Quinn gets one in the same episode; guarding the DeathTrap that Catwoman has been placed into when Batman comes calling, when Batman captures her Harley smugly gloats that he can either beat her up or save Catwoman, and [[SadisticChoice can't do both]]. Unfortunately for her, she's neglected to consider the large circuit breaker the two are standing beside, and when he [[TakeAThirdOption just shuts the power off]] her expression and reaction is even ''more'' priceless:
---->'''Harley:''' ''(Weakly)'' Heh, heh... good call. Help!
** "Joker's Favor":
*** Regular Gothamite [[ButtMonkey Charlie Collins]] is driving home after a miserable day at work when some jerk cuts him off on the freeway. Charlie pulls alongside the other driver, rolls down his window, and proceeds to [[GoshDangItToHeck cuss and threaten the other driver]]... until said driver turns and gives him a [[ComicBook/TheJoker BIGGGG smile]]. Charlie's face is pretty much distilled OhCrap at that point.
*** Charlie returns the favor by trapping the Joker in an alley with a bomb. Joker is absolutely terrified, thinking he's actually going to die, and cries out for Batman to save him. [[spoiler: Batman is actually about twenty feet away, watching the whole thing, and Charlie knows it. But Batman lets the Joker sweat for a few minutes before trying to stop it... and revealing that the bomb was a fake all along (and Collins knew it).]]
** "Fear of Victory," when a [[FacelessGoons bookie's henchman]] is sent to find out why "Mr. Lucky" never loses, no matter how many bets he places. The henchman follows Lucky to an abandoned horse stall, threatens him, and goes to pull him out of the shadows... only to find out he has just collared [[MadDoctor the Scarecrow]]. Things go downhill from there.
** And of course there's also "Two-Face, Part 1," when [[SplitPersonality Big Bad Harv]] takes control over Harvey Dent:
---> '''Harvey:''' There's just one problem.
---> '''Rupert Thorne''': What's that?
---> '''Harvey''': You're talking to the wrong Harvey.
* The scene from the episode of ''WesternAnimation/StaticShock'' where the Joker shows up to cause trouble in Static's neck of the woods. At the end he's been defeated and tries his famous joybuzzer trick on Batman, but Static grabs his hand instead. He gets an Oh Crap look he gets when not only was his joybuzzer ineffective, but Static decides to return the favor in [[ShockAndAwe his own way]]. The Joker was [[{{Pun}} very shocked]] by that turn of events.
* ''WesternAnimation/SupermanTheAnimatedSeries''
** "Solar Power", this is essentially Luminus' expression when he realizes that the [[BroughtDownToNormal depowered]] Superman is returning to normal.
** Same reaction for several alien bounty hunters in "The Main Man", Superman tricks them into throwing him into an Earth-like habitat aboard the Preserver's ship, [[ThemeMusicPowerUp cue theme music]].
** "[[Recap/SupermanTheAnimatedSeriesS3E8SupermansPal Superman's Pal]]" gave Metallo a brief one when he realized that ComicBook/JimmyOlsen had just removed his Kryptonite power source. He has time for a brief shriek before he collapses.
* In one ColdOpening to ''WesternAnimation/BatmanTheBraveAndTheBold'', Wildcat is confused as to why he should be careful around Bane, noting how scrawny he looks. By the time he looks back, Bane's beefed up on Venom, causing the elder hero to utter "Oh, crud..."
* On ''WesternAnimation/DrawnTogether'', Xainder has these a lot, more often than not due to Captain Hero.
* ''WesternAnimation/TheDreamstone'':
** Used repeatedly by the Urpneys (especially Frizz), usually when a plan goes horribly wrong or [[BadBoss Zordrak]] goes into one of his [[UnstoppableRage epic tantrums]] [[YouHaveFailedMe as a result]].
** Played with in the episode "Electric Eggs", after the Urpneys bump into Rufus and Amberley, expecting the worst, only for the latter to perform this trope as well and run for it.
** Rufus, Amberley and Albert pull a particularly epic one in "The Dream Beam Invasion", when Frizz and Nug start growing to enormous size and give them quite a nasty glare.
* The season 2 finale of ''WesternAnimation/DuckDodgers'' has rogue Martian General Z-9 abduct the Martian Queen and steal Duck Dodger's ship as he leads an armada to Earth. However, it is not Z-9 who has the Oh Crap! moment, even when he realizes that he doesn't, as he'd hoped, have the satellite defense codes.
--> '''Counselor Dish''':''Shall we call off the attack, General?''
--> '''General Z-9''':''Maintain course, Counselor Dish.''
--> '''Counselor Dish''':''But, no Martian ship will make it through the shields. We'll be vaporized.''
--> '''General Z-9''':''[[CrowningMomentOfAwesome We're not]]'' '''in''' ''[[CrowningMomentOfAwesome a Martian ship.]]''
--> '''Duck Dodgers'''(On a pursuing Martian ship): '' '''[[OhCrap WE ARE!]]''' ''
* ''WesternAnimation/DuckTales1987'':
** "[[Recap/DuckTalesS1E4WhereNoDuckHasGoneBefore Where No Duck Has Gone Before]]": A lot of the protagonists (and the antagonist) have their own terrified reactions as they realize that they're really in space with real aliens.
** In "[[Recap/DuckTalesS1E53HeroForHire Hero for Hire]]", Launchpad visits Ma Beagle. He saw a picture of her with her children... the Beagle Boys.
** "[[Recap/DuckTalesS1E58TilNephewsDoUsPart Til Nephews Do Us Part]]": After Millionara Vanderbucks loses Scrooge and Flintheart consoles her, he gets this when she asks if there's a "MRS. Second Richest Duck in Duckberg."
* The ''WesternAnimation/DungeonsAndDragons'' cartoon usually kept with the 80s theme of nobody dying or seriously trying to kill the villain except for the episode "The Dragon's Graveyard" where the heroes, fed up with BigBad Venger decide to finish him for good. The look on his face when he realizes he is trapped and they are out to finish him says it all.
* The ''WesternAnimation/EarthwormJim'' cartoon gave many of these moments to its villains, particularly to Psycrow, as in: "...You're gonna hit me really hard now, aren'cha?" But special mention has to go to the OhCrap moment they ''work in to a musical number''.
* The characters of ''WesternAnimation/EdEddNEddy'' got three in quick succession in the last ten minutes of the GrandFinale [[TheMovie Movie]]: [[spoiler: Eddy, when his brother demanded that he "play Uncle", Double D when Eddy's brother starts beating the shit out of Eddy, and everyone else when Eddy's brother starts to beat up ''Double D'' using Eddy as a club]].
** [[spoiler: Eddy's Brother when he sees a steel door rocketing straight toward him.]]
* ''WesternAnimation/FamilyGuy'':
** Brian and Stewie share this moment after getting their hands stuck together in the episode "Stuck Together, Torn Apart".
---> (Both read the industrial glue '''Never Comes Unstuck''')\\
'''Brian''': Oh...\\
'''Stewie''': Crap.
** Also uttered by Peter when realizing that he is to fight Ernie the Giant Chicken for the third time.
*** It's practically Peter's {{catchphrase}}.
** Brian and Stewie when they find out the present Jesus gave Peter was [[spoiler: [[EarWorm a Surfin' Bird record]]]].
--->'''Meg:''' What did he give you?\\
'''Peter:''' Oh you haven't heard?\\
'''Stewie:''' '''''CRAAAAAAAAAAP!!!''''' ( Or '''''[[AtomicFBomb FUUUUUUCK!!!]]''''' in the uncensored version)
* In ''WesternAnimation/TheFlightOfDragons'', when Carolinus realizes that [[spoiler: not ALL of the dragons have been put to sleep. Ommadon's dragon Bryagh is still active]].
* In ''WesternAnimation/{{Futurama}}'', one of Bender's more [[CatchPhrase common expressions]] is "I'm/We're boned!", for more or less these kinds of situations. He gets himself into trouble a ''lot''. Another CatchPhrase of his is "Cheese it!", also for these kinds of situations.
* In ''WesternAnimation/{{Gargoyles}}'', The normally unflappable Owen gets one when Anastasia Reynard says that she's remarried her first husband. Why this is is a mystery until both their true natures have been brought to light.
* In the ''WesternAnimation/GIJoeARealAmericanHero'' episode "The Gamesmaster", Flint has this look when, after challenging the Gamesmaster to a fight, the Gamesmaster stands up from his chair and is revealed to be over ten feet tall.
* ''WesternAnimation/GIJoeRenegades'':
** James [=McCullen=], [[MuggingTheMonster after trying to play hardball with Cobra Industries]], gets an ''epic'' one after Adam [=DeCobrey=] reveals his true identity as Cobra Commander.
** In an earlier one, Scrap-Iron gets an awesome one in slow-motion when a mech-suit equipped, UnstoppableRage-fueled [[spoiler: Roadblock]] sends a missile he fired [[CatchAndReturn right back at him]].
* ''WesternAnimation/HeyArnold'': The episode "Arnold Betrays Iggy" has two such moments. Arnold, he promised Iggy to not tell anyone that he wears bunny pajamas, has a moment of StunnedSilence when Sid and Stinky manage to figure it out on their own. Later, as Iggy is about to make Arnold go out in public wearing bunny pajamas for his alleged betrayal, he overhears Sid and Stinky talking about how they "kinda pulled the truth out of him" and realizes Arnold was telling the truth, just before he steps out for his humiliating walk-of-shame.
* Both main characters of ''WesternAnimation/InvaderZim'' have been on the receiving end on this trope on several occasions, the most obvious example being when Dib sees the massive water balloon about to crush the city (and him) in "The Wettening". Even secondary characters aren't immune, with the Tallests (along with their entire crew) displaying classic Oh Crap expressions as their ship, being controlled by Zim, is about to crash into a sun.
* The intro to ''WesternAnimation/InspectorGadget'' has Gadget do this right when he sees he's handcuffed himself to a lit bomb.
* ''WesternAnimation/JimmyTwoShoes'':
** Lucius gets a particularly good one when he sees an [[EmbarrassingOldPhoto embarrassing old home movie]] playing for all of Miseryville to see.
** He gets a great blink-and-you'll-miss-it OhCrap face in "There Will Be Snow" when Sammy flattens him while wearing a [[HumongousMecha giant mechanical suit.]]
* In ''WesternAnimation/{{Jumanji}}'', Ibsen has quite a few of these, his response is often a small, weak "Oh dear" or some variation.
* In the end of ''WesternAnimation/KimPossible -- [[TheMovie Sitch In Time]]'' we don't see [[TheDragon Shego's]] face while she is witnessing [[YouSuck Ron's]] sudden [[Awesome/KimPossible Crowning Moment Of Awesome]], but the fact that she actually begins to flee from him tells a great deal.
** Drakken also has a MoodWhiplash "Oh, crap!" moment from gloating until when he realizes Shego must also be wearing a Moodulator like Kim, which he just locked into "an irreversible frenzy of rage":
--->'''Drakken''': A scorned woman! [[EvilLaugh HAHAHA!]] The perfect weapon!\\
'''Dr. Cyrus Bortel:''' If she's wearing Moodulator #1, then where is the second one?\\
'''Drakken:''' The ''second'' one?... Uh-oh...\\
'''Shego''': '''''[[SayMyName DRAKKEN!!!!]]'''''
** And Ron had one shortly before, after the inventor informed him that Kim was now locked in an "irreversible frenzy of rage...so I hope she's not angry at anybody because ''whoof''...[[{{Understatement}} that'd be bad]]." Ron had just given her the [[LetsJustBeFriends "let's just be friends"]] talk.
** When gloating about having defeated Kim, Drakken [[http://caps.kpfanworld.com/view/std/Image2424.jpg looks up]] from his knees to see... one very pissed off [[http://img19.imageshack.us/img19/1091/copyofsupersuitpannobla.jpg Kim]]. So scared is he that he only reacts after she punches him across the room.
** And Kim's not invulnerable either. She has this reaction upon meeting Oliver, the 7 foot tall by 4 foot broad boyfriend of Vivian.
** "Oh snap."
** Both and Kim ''and'' Shego (who was good due to the attitudinator) had this reaction when Ron was turned evil ''[[HereWeGoAgain again]]''.
-->'''Kim:''' Not again.\\
'''Hego:''' What happened to him?\\
'''Shego:''' I think he's evil now.\\
'''Hego:''' How bad could that be?\\
'''Shego:''' [[SuperpoweredEvilSide You'd be surprised.]]
* ''WesternAnimation/KingOfTheHill'':
** Buck Strickland's immediate reaction to Peggy bursting into the bar he's holed up in after driving Hank to embarrass himself out of a job.
--->'''Buck:''' [[ThisIsGonnaSuck Oh hell, this ain't gonna be good]].
** In another episode, Kahn's mother comes to visit, and starts busybodying over Minh's meal. Connie walks in to say "hello", sees them fighting, and says "Oh no, already?" before quickly leaving.
** In another episode, the insane Trip Larsen tries to commit murder-suicide with Luann by taking her through the pig slaughtering machine at his pork product factory. Luann manages to escape, but he stays on the conveyor belt, LaughingMad and still intending to kill himself. Before he reaches the grinder, he gets an electric shock right to the head which cures his insanity... just in time for him to realize exactly what he's doing and where he's headed.
* The Disney short ''Lambert the Sheepish Lion'': A mean, hungry wolf is about to chow down on Lambert's sheep mother - until Lambert lets out a ''huge'' roar, immediately changing the look on the wolf's face.
* ''WesternAnimation/TheLegendOfKorra'' is shaping up to have just as many of these moments as [[WesternAnimation/AvatarTheLastAirbender its predecessor]]. For example, in "[[Recap/TheLegendOfKorraS1E1WelcomeToRepublicCity Welcome to Republic City]]", [[MuggingTheMonster three mob members try to attack Korra]]. When she effortlessly redirects a water bending attack and freezes the guy's face, his expression becomes stuck as this. By the end, with Korra besting them with ''three'' elements, that's all they can express.
** In the second episode, Korra participates in a pro-bending tournament. Tenzin hears about this, and comes to retrieve her. Korra gets knocked off the platform during the tournament, and as she swims to the edge, Tenzin is standing not five feet from where she pulls herself up. She tries brushing it off casually, with only slight amounts of success.
** In "When Extremes Meet", this is Korra's ''priceless'' reaction to Ikki revealing to Asami, Mako's girlfriend, that Korra [[LoveDodecahedron loves Mako]]
** In the same episode, Korra gives one when she realizes [[spoiler:Tarrlok can bloodbend]] and in the next episode Tarrlok gets one when [[spoiler:Amon resists his bloodbending]].
** In the season finale, Amon [[spoiler:when Korra finally starts airbending and when it's revealed to his followers that he's a waterbender and bloodbender]]. These are the only two times in the series where his unflappable demeanor goes away. It's also the only time in the series where he has no plan to fix it.
** Pema pulls one heck of an OhCrap face when Asami and Mako start to argue.
** The reveal of the Colossus to the outpost in Book 4.
* In ''WesternAnimation/LegionOfSuperHeroes'', when Imperiex realises that by [[spoiler:turning the sun yellow, Brainic 5 effectively turns the whole population of Kandor into Supermen]].
---> '''Imperiex:''' [[spoiler:I suggest we worry about unshrinking ourselves WHEN THERE ISN'T AN ARMY OF SUPERMEN BEARING DOWN ON US!]]
** That Dark Circle guy's face when he [[spoiler:pushes the trigger for a bomb supposed to blow up a satellite but it fails to go off]] is classic.
** Dr. Londo's pretty good at pulling these, first was when his [[TheDogBitesBack mutated creatures turn on him]] and the second time [[spoiler: has his clone]] display an even more accurate depiction of this trope when his attempt of reasoning with his berserk son fails [[spoiler: who subsequently kills him]].
* ''WesternAnimation/LooneyTunes'':
** This is Wile E. Coyote's standard expression whenever he realizes his plans are about to [[HoistByHisOwnPetard backfire yet again]], which is about every thirty seconds or so.
** Often accompanied by a [[TalkingWithSigns Sign]] bearing a very redundant "Uh-Oh" or similar.
** Perhaps his foe the Road Runner's single display of personality was performing one of these when Wile makes a genuinely intimidating scheme in "The Solid Tin Coyote".
** Likewise, WesternAnimation/DaffyDuck has his "Oh, no, not again" moments, or alternatively:
--->''"... mother."''
*** Most Creator/WarnerBros characters say that or "... mother." See: Sylvester the Cat and even WesternAnimation/BugsBunny.
** Even Bugs Bunny had moments like this; once in a MadScientistLaboratory when he sees the Hyde-like monster behind him, and again when he accidentally takes off in a rocket and looks down to see the Earth falling away below him, and an epic one in ''Rebel Rabbit'' when he saw the ''whole US Army'' coming after him... And then there's ''WesternAnimation/WhatsOperaDoc'' when Elmer shows of his magic helmet's power for the first time.
*** Creator/ChuckJones is clearly the undisputed master of the cartoon Oh Crap face.
*** You know Bugs is in '''''serious''''' trouble when his eyes widen and ears fall.
** "[[UsefulNotes/AdolfHitler Ach! A gremlin from the Kremlin!]]"
** In a lot of cartoons with WesternAnimation/YosemiteSam, he thinks he has gotten the better of Bugs, only to realize he's in trouble, and goes from an EvilGloating to and EvilLaugh and then to an OhCrap rather quickly. For example, in "Hare Lift" when he parachutes out of the plane with his stolen money:
-->'''Sam:''' [[SoLongSuckers So long, sucker!]] [[EvilLaugh Ah, ha, hah, hah, hah!]] Ah, hah, hah, hah, hah! Ah, hah... ''(Notices he's about to land right in the middle of some angry police officers.}'' Ah huh... Uh uh... ''(Lands)'' [[OhCrap Oooh!]].
* ''WesternAnimation/{{Metalocalypse}}'', "[=DethHealth=]": Nathan Explosion gets one of these in this episode. The usual mayhem goes down at a Dethklok show, with much of the debris nearly missing crushing the band:
-->'''Nathan Explosion:''' ''(with requisite expression)'' Oh shi-- we nearly died!
** The guys' reactions when Offdensen angrily confronts them about booking a gig in Syria definitely qualifies. Considering that it's the closest Offdensen has ever gotten to completely losing his composure, even some of the '''''fans''''' had Oh Crap reactions to it.
* In the WesternAnimation/MickeyMouse short ''[[WesternAnimation/ClassicDisneyShorts The Pointer]]'', when Mickey turns around and realizes that whom he thought was Pluto is actually a {{bear|sAreBadNews}}. ''While looking right into the bear's jaw.''
* Occurs several times in ''WesternAnimation/MrBogus'':
** Twice in the episode "[[Recap/MrBogusS1E1MeetMrBogus Meet Mr. Bogus]]" does this happen. Bogus gets one when he sees that part of the rafter that he had been skateboarding on had been gnawed away by Ratty, while Jake and Butch also get this reaction when they see the lawnmower, with Bogus on it, heading in their direction.
** In the episode "[[Recap/MrBogusS1E5ShopAroundTheClock Shop Around The Clock]]", the white rats get this reaction in the second act when they see the dalmatian head their way, intent to fetching the dog treat that Ratty threw on top of their cage. Bogus also gets one before getting hit by a blue squeak toy that Ratty and the white rats have catapulted at him.
** In the third act of the episode "[[Recap/MrBogusS1E10MuseumMadness Museum Madness]]", Ratty gets one before Mole inadvertently knocks him off the plank of the pirate ship. He gets another one a little later afterwards when Mole also inadvertently causes the cannon to tip down while trying to fire a shot, before the shot causes the pirate ship to sink.
** Bogus and Tommy both get this reaction in the first act of the episode "[[Recap/MrBogusS1E11LightsCameraBogus Lights, Camera, Bogus]]", when Brattus gets eaten by the robot dinosaur.
** Two examples in the episode "[[Recap/MrBogusS1E13GoodSportBogus Good Sport Bogus]]"; the Dirt Dudes both get this reaction in the first act when Bogus uses his spaceship to fire a stream of water that blasts them away, and Bogus himself gets a rather [[CrowningMomentOfFunny hilarious one]] in the third act when he sees the arrow soaring directly toward the archery target that he's stuck in.
** In the first act of the episode "[[Recap/MrBogusS2E1ComputerIntruder Computer Intruder]]", Bogus and Baddus both get this reaction upon discovering the huge and evil Bogus clone playing them for saps against each other.
** This was Ratty and Mole's reaction near the end of the third act of the episode "[[Recap/MrBogusS2E2BabysittingBogus Babysitting Bogus]]", when they realize that there's no way for them to escape the baby.
** In the second act of the episode "[[Recap/MrBogusS2E4BookstoreBogus Bookstore Bogus]]", Bogus gets this reaction before crashing into the bookshelf, while in mid-flight while pursuing Ratty and Mole.
** Bogus gets this reaction when he realizes that he's about to get smacked by the tube of toothpaste that he just jumped over in the first act of the episode "[[Recap/MrBogusS2E5BadLuckBogus Bad Luck Bogus]]".
* ''WesternAnimation/OKKOLetsBeHeroes'': [[BigBad Lord Boxman]] simply says "Poop." when he sees one of his robots slowly backing into and about to destroy his factory.
* WesternAnimation/ThePenguinsOfMadagascar are no strangers to this facial expression. They even get one during the opening sequence.
* ''WesternAnimation/ThePowerpuffGirls''
** Buttercup is hit with this twice in "Moral Decay", first when she accidentally knocks out one of Bubbles' teeth and again when villains gang up on her to beat her up.
** Fuzzy Lumpkin's reaction in "Impeach Fuzz" just before receiving a beat down from [[CrouchingMoronHiddenBadass the Mayor.]]
** Happens twice in "Lying Around The House", first to Buttercup after she breaks the Professor's trophy, and to Bubbles when she realizes she accidentally drew on the walls.
** All three of the Powerpuff Girls have this facial expression in "Twisted Sister" when every non-superpowered villain in Townsville gangs up on them to beat them up.
** Also in "Twisted Sister", Bunny suffers this just before [[spoiler: exploding]].
** Blossom [[http://vignette2.wikia.nocookie.net/powerpuff/images/d/d8/VSB6.jpg/revision/latest?cb=20131228012547 has several of these reactions]] in "A Very Special Blossom".
** Blossom, Bubbles, and Buttercup are hit with this in "The Boys Are Back In Town" when they see the now-gigantic Rowdyruff Boys, and again at the end when Him tells them they may not be so lucky the next time they deal with the Boys.
** Buttercup has this face when she gets busted for throwing glue at Elmer in "Paste Makes Waste".
* Megabyte from ''WesternAnimation/ReBoot'' is not only a stoic and sophisticated [[TheChessmaster Chessmaster]] and master manipulator, but also the most physically-powerful program in Mainframe. His memories of Enzo Matrix are of a brash, overconfident, hyperactive little boy. So when the now grown up FutureBadass calling himself Matrix falls for his goading, tries to beat him up personally, ''lands one'', and ''leaves a fist-sized dent in his chest''... it's one of the best facial expressions in the series.
** Later that same episode, [[spoiler: after Matrix defeats him, and [[CruelMercy refuses to kill him]], Megabyte prepares to escape Mainframe ''anyway'' by using a portal to the Supercomputer. Then Mouse hacks the portal to send him to the Web, instead]]. His reaction when his last gambit fails says it all.
* ''WesternAnimation/RegularShow'':
** Muscle Man has a tendency to say "Oh no, bro!" when things start to get bad.
** There also a couple usage of this trope: Benson saying "We're dead" in "Dizzy" and Mordecai saying the exact same thing at the ending of "Party Pete".
* Both Ren and Stimpy get one in ''WesternAnimation/TheRenAndStimpyShow'' short "Nurse Stimpy" when both characters don nurse outfits to take care of the other, Stimpy more than Ren when he realizes that Ren's doing it as revenge.
* Played for ''raucous'' laughs in an episode of ''WesternAnimation/RockosModernLife''. One of his new jobs in a long string of job hunting results is him working at what is for all intents and purposes a ''phone sex'' setup (this series got ''[[GettingCrapPastTheRadar a lot]]'' under the radar). Of course, when he and the person on the other line recognize one another's voices...
-->'''Rocko:''' ''(monotonic, unenthusiastic)'' Oh baby, oh baby, oh baby...\\
'''Mrs. Bighead:''' ... Rocko?\\
'''Rocko:''' ... ''Mrs. Bighead''?!\\
''(both slam the receivers down on their respective phones)''
* ''WesternAnimation/SamuraiJack'':
** The eponymous protagonist spends a good portion of episode 2 like this, having been flung into the [[CrapsackWorld dystopian future]] where he's falling between skyscrapers and getting hit by flying cars and ''[[FishOutOfTemporalWater nothing makes seeeeense]]''. Poor guy.
** [[BigBad Aku]] gets an absolutely [[CrowningMomentOfFunny hilarious]] one when [[EmpathicWeapon Jack's sword]] doesn't harm Jack to the point that his flaming eyebrows snuff out!
** [[http://www.youtube.com/watch?v=Uwbqr2UjeSg No, jump good!]]
** The [[http://i.imgur.com/3VKr1a9.jpg look of utter confusion and horror]] on Jack's face when he finds his sword, a sword forged by the gods and the only thing capable of harming Aku ''doesn't work on the Minions of Set''. He cuts one's arm off and then nearly slices it in half, but the damage heals instantly. As if they weren't already impossible to fight as is. Jack spends most of the episode looking like this.
** Aku gets this expression whenever Jack gets the jump on him; for all that he's an immortal sorcerer, Jack's sword is still the one thing that can destroy him forever, and Jack is a master of it.
** None exceed Aku's dawning horror in the finale, however, when [[spoiler:Ashi opens a time portal that sends her and Jack back to the past]]. Except perhaps [[spoiler:past Aku's expression when future Jack emerges mere moments after past Jack was sent away. An expression that remains on his face for the final few minutes of his existence]].
* Invoked numerous times on ''WesternAnimation/{{Sealab 2021}}'', but especially notable during Quinn's MushroomSamba episode with the seal, Stinky Pete, being chased by a shark.
--> '''Stinky Pete:''' Oh crap, oh crap, oh crap, oh crap, oh crap, oh crap, OH CRAP ON A CRAP CRACKER!!
* Doyle does this (even going so far as to utter "Oh crud!") as he notices the time has run out on his emergency air supply in ''WesternAnimation/TheSecretSaturdays'' episode "Where Lies the Engulfer".
* ''WesternAnimation/TheSimpsons'':
** When Krusty gets arrested for tax evasion, we see one side of a telephone conversation with his banker in the Cayman Islands.
--->'''Banker:''' Hoho, I'm sorry, I can't divulge information about that customer's secret illegal account. ''(hangs up)'' ... Oh crap, I shouldn't have said he was a customer. Oh crap! I shouldn't have said it was a secret. ''Oh crap!'' I ''certainly'' shouldn't have said it was illegal!... Oh, it's too hot today.
** In a "Treehouse of Horror" spoof of the Omega Man, Comic Book Guy does this as a nuclear missile hits him dead on in the face.
--->'''Comic Book Guy:''' But Aquaman, you can't marry a woman without gills! You're from two different worlds! ''(looks up and sees missile)'' ... Oh, I've wasted my life.
** Troy [=McClure=] gets a literal "Oh Crap" moment when, during an infomercial for Dr. Nick's Juice Loosener, he tries on Dr Nick's Tanning Cream/Laxative.
** Bart Simpson has one of these moments after he burns his name into forty-foot long letters on Springfield Elementary School's athletic field with grass killer. An enraged Principal Skinner roars Bart's name after seeing it, and Bart gulps both audibly and nervously. He then has another moment when Skinner is yelling at him in his office:
-->'''Skinner:''' Surely you realized that by writing your own name in forty-foot letters, you would be caught.\\
'''Bart:''' Maybe it was one of the other Barts, sir.\\
'''Skinner:''' THERE ARE NO OTHER BARTS!!!\\
'''Bart:''' Uh oh.
** Near the end of "Marge vs. The Monorail", SmugSnake Lyle Lanly loses his smug expression and freaks out when he realizes that his plane to Tahiti is making a stop at North Haverbrook, the last town he ruined with his monorail scam. His panic is justified -- moments after the plane lands, an angry mob of North Haberbrook's remaining inhabitants attacks it.
** In "Marge in Chains", Otto sunbathing on a rooftop, just as he realizes he's about to be hit by a dollop of vomit infected with the dreaded Osaka Flu falling from Arnie Pie's helicopter. Shown from the perspective of said dollop.
** "And now a word from our new sponsor...'''PERCODAN?!?''' AW CRAP!"
** Nelson in "22 Short Films About Springfield", when he realizes that the Very Tall Man has stopped his car and is coming after him for laughing about his appearance. (Then again, after Lisa tells the guy that Nelson is hiding down the manhole.)
** In the segment "Citizen Kang" of "Treehouse of Horror VII", Homer has this when he realizes that he just launched Bill Clinton and Bob Dole out of the UFO tubes and into space, killing them and dooming the Earth to vote between their alien impersonators.
-->'''Homer:''' Oh no.
** In "Bart Has Two Mommies", Homer has this reaction when he takes a bite out of a peach and remembers that he filled it with antifreeze to poison the monkey that kidnapped Bart. We don't get to see him get sick from it.
* ''WesternAnimation/SouthPark'':
** In the episode "Child Abduction is Not Funny", the owner of the city wok does this absolutely according to the book: He gives a big speech, realises something's wrong, sees the fuse, follows it with his eyes, says "Oh Crap" and gets blown away, together with part of his wall.
** In "Imaginationland Part 2", Stan has a '''massive''' one when he realizes that [[ItMakesSenseInContext the government strike team to Imaginationland led by Kurt Russel]] hare about to be attacked by [[spoiler: The Woodland Christmas [[CallBack Critters]] from Cartman's story in "Woodland Critter Christmas"]].
** Oh Crap is more often than not said outright (mostly by Stan, Cartman, Kyle and Kenny).
* ''WesternAnimation/SpongeBobSquarePants'':
** Used by Mr. Krabs in an episode when [=SpongeBob=] tries to free the captive jellyfish from him:
--->'''[=SpongeBob=]:''' And now I'm going to set these jellyfish free!\\
''(attempts to open the door)''\\
'''Mr. Krabs:''' *laughs* Well, you can't. The door's voice activated, and it will only open if I say "Open".\\
''(short {{beat}}, then he suddenly realizes ''that he just said it'')''
** In "Friend or Foe", Plankton simply says "Oh, barnacles." when he deploys a jetpack only to see that it's upside-down, causing it to send him flying through the floorboards of the Krusty Krab.
* ''WesternAnimation/StarWarsTheCloneWars'': In the first episode, Yoda faces an entire division of Separatist battle droids and armor, at which point one of the droids calls Ventress.
-->'''Ventress''': What's he doing?\\
'''Droid''': He's just sitting there.\\
'''Ventress''': (''eyes go wide'') SHOOT HIM! SHOOT HIM NOW! (''cue Yoda jumping up and taking the entire unit apart'')
* ''WesternAnimation/StarWarsRebels'': In "An Inside Man", Ezra and Kanan are disguised as stormtroopers when the Imperial facility is placed under lockdown. Recurring adversary Agent Kallus orders the two to follow him into a lift. Once inside, they realize Kallus knows who they are. [[spoiler:Then immediately subverted when Kallus utters [[MysteriousInformant Fulcrum's]] [[SpySpeak code phrase]].]]
* ''WesternAnimation/StevenUniverse'' "Jailbreak": This is Peridot's reaction to Steven {{No Sell}}ing her gem disruptor by grabbing it in his hands mid-swing without it having any real effect on him.
** Amethyst's reaction when she realizes even after her weeks of training to fight Jasper, her strongest attacks barely have any effect, and is about to get [[CurbStompBattle Curb-Stomped]].
* ''WesternAnimation/TeenTitans'':
** It's a blink-and-you'll-miss-it moment, but Slade got a ''really'' good one in the episode "The Prophecy". Particularly sweet, because up until that point, Slade had been the [[TheStoic stoic,]] [[TheQuietOne quiet]], [[TheChessmaster chessmaster]] villain. Then Raven shows up and gives him a good old-fashioned ass kicking.
** Of course, Slade himself tends to generate these moments too, especially during Season 4 [[spoiler:when he comes back from the dead as TheDragon of [[BigBad Trigon]]]]. The Titans got a ''collective'' OhCrap look when they first saw him.
** Slade also gets a very quick one in "Betrayal" after he shoots Beast Boy. When he looks up after briefly taunting Terra, he briefly goes (one-) wide-eyed to find himself facing one very ticked off [[BearsAreBadNews giant green bear]].
** Doctor Light gets a classic one. After gloating and preparing to make his getaway, Raven shows up behind him, in full scare the crap out of you mode, with that immortal line "Remember me?" Light's face goes white, and he calmly asks to go to jail.
* Several times during the 2003 ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 Teenage Mutant Ninja Turtles]]'' series, especially involving The Shredder.
** One of the biggest ones is when Leonardo is sent crashing through the window of April's apartment, nearly dead. In rage, Raphael is about to leave to find out who was responsible and make them pay, when Leonardo struggles to talk and stops him from leaving. His last words before losing consciousness??
--->'''Leonardo:''' He's back.... The... Shredder... ''(passes out)''
*** The look of fear and shock on everyone's faces afterwards is amazingly effective.
* ''WesternAnimation/ThomasTheTankEngine'' uses this a lot. Each engine model has a scared face that's absolutely perfect for this. Commonly seen when an engine's train becomes a {{runaway|Train}}. A good one would be in "Old Iron". James is cruising along light engine (due to some naughty boys climbing into his cab and playing with his controls), enjoying himself. Then he notices he's going faster and faster, and realizes his cab is empty. "What shall I do? I can't stop! '''HELP! HELP!'''"
** Diesel 10's arrival and some of his actions in TheMovie produce this reaction as well as ThisIsGonnaSuck.
** It's generally agreed, however, that the most infamous of all the OhCrap faces is the [[http://i1.kym-cdn.com/photos/images/newsfeed/000/303/125/8a4.jpg "O" Face]].
* ''WesternAnimation/TimeSquad'', the main three characters are prone to giving these looks whenever something terrifying is about to go down, for example when an airplane flown by the Wright Brothers or an evil My Little Pony comes charging after them.
** In "Hate or Let Hate", Otto is stranded on a deserted island that's only inhabited by baboons. The boy gets cornered by the monkeys, and as he trembles in fear he mutters, "Aw Crud. . ."
* In ''WesternAnimation/TinyToonAdventuresHowISpentMyVacation'', Shirley the Loon (and everyone else in the theater) freaks out when the THUD Sound System promo kicks in. For good reason, too!
* Done often in ''WesternAnimation/TotalDramaIsland''. For example, when Owen has to get a key from a sleeping bear:
-->'''Owen:''' Oh crap oh crap oh crap!\\
''(the bear puts Owen's head in its mouth, still sleeping)''\\
'''Owen:''' ''(whispering)'' Oh crap... ''(the bear wakes up)'' Crap infinity...
** Also done whenever the season's MagnificentBastard thinks that he/she is about to be voted off.
* ''WesternAnimation/TransformersAnimated:''
** The look of ''pure abject horror'' on Optimus Prime's face when the restored Megatron (whom he'd thought dead since the first episode) bursts out of Sumdac Tower is priceless. This is a 'bot who understands ''exactly'' how completely and utterly screwed he is.
** The Elite Guard get a big one when, after insisting for the entire episode that there are no Decepticons on Earth, they face off with Starscream, who is more than willing to show the lot of them a taste of what Optimus has been up against.
*** Ultra Magnus has a pretty good one. After telling the Autobots to stand back, he presumably intended to deal with the situation. As soon as he turns around, Starscream has recovered and is pointing his weapons right in Magnus's face. *[[TheWorfEffect blast]]!*
*** [[MemeticMutation He just couldn't deal with that now.]]
** The Decepticons get their own when the Autobot ship transforms [[spoiler:into a revived Omega Supreme]].
*** And again in [[spoiler:"Transwarped" (the season 3 premiere)]]:
---->[[spoiler:'''Starscream:''' Omega Supreme?!?! [[UnusualEuphemism ... We're slagged.]]]]
* ''WesternAnimation/TransformersPrime'' finally gets in on the action. [[spoiler: After doing everything in his power to prevent it, Megatron fails to keep Optimus Prime from obtaining the Star Saber, a legendary weapon that can only be used by a Prime. Prime uses the sword to not only cleave in two a mountain that was just dropped on him, but to fire a SwordBeam at the Decepticon warship. Megatron's reaction is less than positive, as he calls this the Decepticons' darkest hour.]]
* Dr. Venture of ''WesternAnimation/TheVentureBrothers'' pretty much whenever he screws up or pisses someone off.
* ''WesternAnimation/WackyRaces'': Dick Dastardly has several, but most memorable was in the episode "The Dipsy Doodle Desert Derby" in which he enlists the assistance of Bubu, a genie he releases from a bottle. Bubu plants the Mean Machine atop a high sand dune, to which Dastardly orders him to put him on the ground. Bubu makes the dune disappear. Dick and Muttley both get an "Oh, crap" look before they drop.
* Sadlygrove of ''WesternAnimation/{{Wakfu}}'' has a fantastic expression when attempting to escape from a flooding room and his {{Love Interest|s}} Eva appears to have drowned.
* In the ''WesternAnimation/WinxClub'' season 2 finale, all good guys present in Realix had this reaction when [[BrainwashedAndCrazy Bloom]] ignored Sky and continued to give [[BigBad Darkar]] the Ultimate Power.
* In the animated version of ''Literature/AWishForWingsThatWork'', Santa lets out a "[[https://youtu.be/mLccxrDgi5U?t=14m30s Ho, ho, ho-oh nooooo!]]" as his sleigh is unhooked.
* ''WesternAnimation/YoungJustice'' has a good one in the 10th episode of the 2nd season, "Before the Dawn."
-->'''Wonder Girl:''' Listen, uh, Black Beetle. You're totally outnumbered. Open those doors now and we'll go easy on you!\\
'''Black Beetle:''' You? Will go easy... on me? Ha ha ha ha ha Ha Ha Ha Ha Ha AHA HA HA '''HA HA HA!!!'''\\
'''Bumblebee:''' Oh, that is not good sign!
