Enemies frequently have this reaction upon encountering the player character late in the game. The target of any superweapon attack also do this. The two words are explicitly dropped in Ace Combat X: Skies of Deception when your allies see that there's another Fenrir in Archelon Fortress trying to escape to Leasath and they can't do anything about it themselves.
Another for the poor Yukes happens during a mission to destroy their ammunition dumps, and they find out that the ammunition fires are burning too hot for their firefighting equipment to handle.
Very Unfortunate Yuke Ground Unit: GET OUTTA THERE, YOU'RE GONNA GET FRIED!
The final mission of Ace Combat 04: Shattered Skies. Yellow Squadron, defending Megalith, is ordered to ignore all incoming aircraft except Mobius One, reasoning that the remaining attackers are of little threat (a signal of how much they fear the player). Then they realize that they're up against a Mobius Squadron.
You're not gonna believe this, Jean-Louis! All of them have ribbon insignias!
The player character's first experience with the Excalibur in Ace Combat Zero: The Belkan War: right after it cuts through three allied transport planes in one attack, you hear about five different pilots loudly wondering what the hell just happened.
Enemy squadrons encountered as an emergency update in Ace Combat Infinity are a frequent source of this; in particular is the Titan squadron of F-14s, the leader of which will start panicking and ask if they still have the advantage after the players shoot down a few of them. Playing in Area B7R Dogfight makes it most apparent, where your mere presence scares almost every possible enemy squadron enough that they immediately call for fire support from Stonehenge.
Vath, the third Lord of Chaos and first Chaos Lord to be a jerkass in his own right, gets an Oh, Crap! moment when the hero destroys both his Chaos Dragon Amulet and his Legendary Sword of Dragon Control via Accidental Aiming Skills. His Oh, Crap! moment gets turned up a notch even more when he realizes that his dragon that he enslaved, Stalagbite, has turned against him now that he has been free of his control.
Vath: (after his sword and amulet are destroyed) No. NO! You fool! You have no idea what you've done! Stalagbite: (wakes up and looks at Vath) You... Vath: No! WAIT! This wasn't supposed to happen! (Stalagbite roars and pins him down)
Zahart, controller of the Eighth Lord of Chaos, Tibicenas, also gets one when he sees that Zhoom has destroyed his magic ring. This happens right before Tibicenas proves that Evil Is Not a Toy by lifting his former master into the air and brainwashing him into his new slave.
Artix also gets one whenever he notices the Fear Feeder and receives sudden fear of it. Pretty unusual for a paladin, if you ask us (He normally only fears the color pink, but still...).
In every version of Animal Crossing, the player's character has this reaction after shaking a tree, and a beehive falls out. And after City Folk, if the player is stung twice, they faint. Taken further if you try to catch either a tarantula in winter or a scorpion in summer during the night and fail, or just simply carrying a net at night and not being aware of your surroundings.
In Archimedean Dynasty the moment comes when, during a routine patrol, a massive Biont battleship silently passes in front of you, knocking out your electronics with its mere presence. And then things go to hell. Really, really fast.
In Arc Style: Baseball!! 3D, an exclamation mark pops out of a baserunner's head when they see that a fielder is trying to tag them out in a rundown and when they need to tag up because the ball has been caught in the air.
Armored Core For Answer: "Please Accept My apologies, the briefing you saw was manufactured. This is the end of the road for you. I think you understand why." Cue 4 Flying into the battlefield. And on Hard difficulty, there are five, with the extra one being the mission control.
Happens late into Assassin's Creed: Odyssey as the Misthios and Deimos fight each other. Kleon shoots an arrow into Deimos's back, making him have this reaction as the Misthios bears down on him and gives him a choice of two deaths: a neck snap or drowning him in a puddle on the beach.
Shown when After Wyzen, now the size of earth, tries to kill Asura by using his finger to crush him, Asura starts lifting it BACK UP! Wyzen has this type of look on his face, before being punched into oblivion.
At the very end of Episode 14, Sergei, the most despicable of the Seven Deities, gets a very satisfying one of these right before getting slashed in half by Wrath Asura.
In Episode 15.5 Yasha vs. Deus, near the end of the fight, when Yasha activates his Vajra and tries to attack Deus with the same punch that broke Asura out of his Wrath form... Deus takes it without even flinching, cue Yasha having this facial reaction.
In Episode 16, Yasha has this look when Asura grows one of his humongous Berserker Arms the instant Deus appears.
In Origins, Shanath gets an incredibly satisfying one when Sagi powers himself up and cripples his machina arma.
In the first game, Melodia had a big one when Kalas ripped off his wing and rejected Malpercio.
Batman: Arkham Asylum: As Batman takes out more and more mooks from the shadows, the remaining mooks will notice their missing (or incapacitated) friends, and they will appropriately start freaking out. All more the fun with detective vision on, since you can slowly see their heartbeat rise and their emotional well-being plummet. This mostly holds true in Batman: Arkham City as well, except for when Batman encounters the Brainwashed and Crazy TYGER troops.
Henry gasps when he sees Bendy's cardboard cutout in the middle of the hallway. And it wasn't there before.
Henry reacts this way upon seeing "Inked" Bendy and makes a break for the entrance.
Even the enemy robots of Berzerk fear Evil Otto, as they herald his arrival by shouting "Intruder alert! Intruder alert!" And for good reason: Evil Otto will destroy anything other than a wall he bounces into, even if that something is a robot.
Right after the final fight in BioShock 2you run down a corridor right behind Eleanor to get to the escape sub before the charges are detonated that will hurl the entire complex into a deep sea trench. Then at the last corner the game changes to dramatic slow motion as Eleanor suddenly stops and it takes a moment for you to get around the corner to see the door blocked by lots of red crates and two gray boxes with blinking lights.
Hazama gets his own in his CS gag reel, where he unwittingly winds up bathing in 100% Spanish Catnip. Tao and two Kaka kittens nom on him uncontrollably, Jubei wants to take in his scent deep before killing him, and Kokonoe wants to sharpen her claws on his chest; it's not until Kokonoe fully explains what his cat allergies are doing to him that the viewer realizes this is effectively the worst day in Hazama's life, and by the end of it all, every feline in Kagutsuchi wants him badly. Run, fat boy, run!!
On a more serious note with Hazama, any time Celica appears in front of him is treated as this — she has the power to suppress seithr, which interferes with the operation of ars magus and the Azure Grimoire, but whereas Ragna's is limited to the right side of his body, Hazama's Azure Grimoire is his body, so when she shows up, his bodily functions slow down to the point of incapacitation. Every time this happens, he screams for an immediate evac from Phantom. This is highlighted at the end of the Six Heroes story — Rachel and Trinity send a wave of illusory opponents at Terumi in order to draw him out and materialize his consciousness in the real world, whereupon Hakumen can kill him. In this story, at the time this happens, he is right next to Hakumen, Jubei, and the aforementioned Celica. He is justified for begging for an escape, because all he can do under those circumstances otherwise is crap himself and await his inevitable doom.
Ragna the Bloodedge often gets these a lot in gag endings, often coupled with a Big "WHAT?!", for plenty of good reasons. For example, he even gets one in Rachel's gag ending when Jin enters, having been attracted by the effects of the Spectacles of Eros.
Ragna: Hey! Not you too?! And what's with those eyes? They're... heart-shaped...?!
Breakdown has quite a few, but there's one that truly stands out. During the section in which Derrick is making his way through the underground , after getting past the hallucination with enemy Alyx clones, if you listen carefully, you'll notice a very familiar bgm playing, but just faintly, evades newly-implemented trip mines, proceeds to open a shutter and then opens a door... then Derrick automatically turns around and Solus is shown to have been RIGHT BEHIND HIM, holy shit...!
Solus: "Object: Human. Hypothesis: Destination Nexus." (points at Derrick)
General Lionwhyte gets two in Brütal Legend. First, before the final Stage Battle against him, when he notices the sword Lars has levelled at his throat, and finally realizes that the resistance aren't just bumbling idiots and will actually kill him if they get the chance. Later, after the battle when a mirror from his tower is about to fall on him, he attempts to stop it... only to shatter it instead and make it even more lethal. The look on his face reflected in the shards of mirror as he realizes just how badly he screwed up is priceless.
During the final gunfight, if you shoot Zakhaev's goons first, you'll have just enough time to see him spin around and give you a priceless "OH SHI-" look right before you shoot him.
Probably the BIGGEST Oh, Crap! moment in all of Call of Duty happens as you assault Zakhaev's base (which is in fact a missile silo). You see a nuclear ICBM launch into the sky (remember, each of them has 6-12 high yield nukes in them...and they only take about 30 minutes to reach their target...and with no warning, it's unlikely to be stopped at all). And then ANOTHER ONE LAUNCHES. You've now got (maybe) 20 minutes to stop World War 3 and The End of the World as We Know It.
Castlevania: Lords of Shadow has a good one after defeating Cornell's human(-ish) first form. The camera cuts to him, hunched over and panting, with an expression that clearly says "how am I losing to this guy?!"
By far the most memorable are by Ozzie, who persistently tries to hinder the team's advance, and appears noticeably disturbed each time he realizes it hasn't worked. Twice in the game, this is augmented with the narrative comment "Ozzie's in a pickle!"
Guardia's Chancellor who is actually the fiend Yakra in disguise also has some visually striking Oh Crap moments, at times when he's suddenly realized that his carefully-planned carefully-executed schemes have instantly unraveled before his eyes.
Case 1: Crono impales the Dragon Tank through a vital component and gets clear, and the Chancellor orders its repair. When it self-destructs, it blows up the part of the bridge he and his two flunkies are standing on, causing them to hang for dear life as a makeshift bridge for Crono and Lucca.
Case 2: The Chancellor and his flunkies corner Crono, Lucca, and Marle in a part of Guardia Forest. Rather than accept a trip back to jail (more proverbial than physical in Marle's case), the three of them jump into the nearby Gate instead.
Case 3: The Chancellor orchestrated King Guardia XXXIII's trial with a forged document and a bribed merchant, even gaining a guilty verdict of four to one on the King. The decision was reversed almost instantly when Marle jumped through the fucking stained glass window and produced a shard of the Rainbow Shell, effectively imploding the plot in his face. This is a case of a Rebellious Princess too wild for an Evil Chancellor to control.
There's also a few scripted instances of this. In the Statesman's Task Force, Dr. Aeon gloats at you from a hidden room, explaining how you'll never escape from your predicament without getting the codes from the 4 Arch-Villains scattered through the zone. He then berates himself for telling you how to escape, and orders one of his goons to erase the recording they just made. The following exchange occurs:
Goon: "Uh, sir?"
Dr. Aron: "What?"
Goon: "You, uh, said you wanted to transmit this, uh... live."
Dr. Aeon: "AAAAAGH! Turn it off, TURN IT OFF!"
Throne of Bhaal features one. As you invade the layer of the Drow Bhaalspawn Sendai, you are repeatedly shown cutscenes of Sendai with her lieutenants. Since by this point your character is easily one of the most powerful mortals on Faerun, when her captain stumbles in stuttering that it's you invading her layer and slaughtering her minions, she falls into an Oh Crap moment that just keeps on getting worse and worse as you leave more and more of her best minions in bloody pieces behind you. It doesn't truly stop until she's dead.
Company of Heroes: So you're cutting a swath through German lines with your M10s and Shermans...and then the Wehrmacht brings up their armor. To quote the Allied tank commanders: "Oh shit, that's a TIGER!" Usually followed by frenzied commands of "Drive, driiiiive!" or, very frequently, loud explosions.
In Crash Bandicoot (1996), during the intro the ordinarily silent Crash lets out an "uh-oh" when he realizes he's run through one of the windows of Cortex's castle in an attempt to flee.
Happens in Cuphead: When Cuphead and Mugman face the Devil in the fight against him that starts up, they both get this reaction when the Devil gives out his Death Glare that plays out what he will do to them, and they both let out a terrifying scream in fright. This is the only battle intro when they get scared out of their wits instead of being prepped up for battle, though they quickly recover their Heroic Resolve and fight like it's now or never.
Seath the Scaleless in Dark Souls roars in fury and likely fear when he realizes that the player is within striking distance of his Soul Jar.
At the end of the Necron Headquarter map, their voice when they realize you have planted a bomb is awesome.
Necron Pariah: My Lord, the living have—(KABOOM)
Most times a stronghold is defeated there will be one of these, for example Eliphas realising he's about to be on the receiving end of a You Have Failed Me, or the entire Tau army before they go into Heroic BSoD when their Ethereal dies, especially in Soulstorm.
The Imperial Guard respond to coming up against Necrons with a terrified "Oh no...not them!" Since most other enemies earn relatively calm phrases like "Orks are in the perimeter", this reinforces that Necrons are really bad news.
Dead Rising 2: Off the Record: Frank actually utters the words after trying to get Chuck Greene's attention... and accidentally grabbing "Katey" by the leg. After the drunken and despondent Chuck had just made it clear how protective he was of her.
In Deep Rock Galactic, the voice callouts for pinging a Bulk Detonator are all variations of this. A Bulk Detonator is a Boss in Mook's Clothing with powerful attacks, burrowing abilities, and a death blast that can potentially wipe out an entire team, so the callout is useful to warn new players that they need to take this thing seriously.
Diablo II sees this at the final cutscene when Marius realizes that the person he gave Baal's soulstone to was actually Baal himself.
In Devil Survivor, Smug SnakeAzuma assumes that he is a Magnificent Bastard, and nonchalantly shrugs off a threat. Much to his shock, however, the one making the threat then proves he wasn't joking, causing Azuma to almost piss his pants and inadvertently blurt out that Naoya was supposed to make the COMPs incapable of harming 'ranking tamers', rendering them useless against the Shomonkai. Only... Naoya didn't. Ass-kicking follows.
Izuna:I've seen angels before but, but that thing's just... it's another order of MAGNITUDE!
Dishonored: Corvo might be The Quiet One but his reaction to seeing the Outsider's mark on his hand says volumes. And performing an assassination on a main target leads to a slow-mo shot of Corvo grabbing them, them turning around, their Oh Crap face, and their death by sword through the chest. And it's unique to each target.
In Donkey Kong Country 2: Diddy's Kong Quest, Diddy and Dixie's reaction to the appearance of bosses is having their eyes cartoonishly bug out of their head. Donkey Kong does it too during the final battle when K. Rool appears defeated only to get back up (At least the first two times...). During the final battle, if you get too close to K. Rool, your Kong will panic right as they see K. Rool smash them with the butt of his blunderbuss which costs you a Kong (or a life if it was your last one) while they get Blown Across the Room.
In Doom³, the space marine is pretty calm when blasting his way through hordes of demons. This changes in the last boss fight, where the expression on the marine's face transforms to one of utter terror when confronted by the fifty-foot tall Cyberdemon. Yes, if you notice the marine mouths the words "Oh shit" (Or Holy shit) just as the camera stares at the Cyberdemon's crotch-guard, and then at his face when the Cyberdemon roars. And to a lesser extent, Doom 1's Cyberdemon fight at the end of the second episode.
In Dragon Age: Origins provides a great Oh, Crap! moment in the Female City Elf origin: shortly after being kidnapped by Bann Vaughan for a "party," the PC ends up in a back room, cornered by two guards who know that she's been trained as a warrior/rogue, about to be tied up for the ensuing atrocities. Then her cousin Soris shows up at the door and tosses her a sword; the guards look from Soris to the PC, and one of them mutters "Oh sod..."
In the cutscene at the beginning of the Battle of Ostagar, Cailan realizes that he underestimated the size of the Darkspawn horde. His expression says it all.
During a trip into the Fade, a helpful spirit will tell the Inquisitor that their only way out will be to defeat an extremely powerful spider demon (which you see upon first entering the sequence, and it's truly massive). The Inquisitor's response is a resigned "Well, shit."
Invoked in the name of the penultimate War Table loyalty mission for Varric: Well, Shit.
In Dragon Ball Fighter Z, Zamasu has this reaction when Vegito fires his Final Kamehameha at him during their Dramatic Finish, just before the former is vaporized by the attack, screaming in pain all the while.
Drakengard 2: Manah has an epicOh, Crap! moment when she first meets the one-eyed man a.k.a. Caim. There's even an FMV devoted to it.
Despite being an unstoppable war machine, Horny from Dungeon Keeper 2 gets a brief 'Oh Crap' moment when he first attacks a Stone Knight, and it just looks at him as his scythe bounces harmlessly off its neck.
With the morale rules in Dwarf Fortress, your military will do this when particularly badly pummelled. Or slightly pummelled. Or as soon as the enemy shows up.
Dagoth Ur from The Elder Scrolls III: Morrowind completely breaks down in a rather short amount of time. In the first encounter with him, he is calm, collected and quite civil, even to the point of carrying a rather lengthy conversation with the player character before fighting him. After Ur retreats, he becomes more noticeably annoyed, but remains confident in himself and berates the player-character for being foolish. It's only when the player-character begins removing the enchantments (that allow Dagoth Ur and the Tribunal to connect to it) from the Heart of Lorkhan that Dagoth Ur loses it. Considering that is one thing he never expected anyone to do, his breakdown is plenty justified.
In The Elder Scrolls V: Skyrim, the first dragon you face screams "No!" when you strike the killing blow and he realizes that you are a Dragonborn, a mortal with a dragon's soul who has the power to permanently kill dragons by absorbing their souls. Another dragon roars in shock when you manage to trap him like a rat. Finally, Alduin has a moment like this when you strike the final blow. He breaks down mentally as his body breaks down physically, protesting that he cannot die.
In the opening to Epic Mickey, Mickey Mouse has this moment when he hears Yen Sid returning (after creating a monster AND spilling paint and thinner on another world)
In Fallen London, during the Governer of Port Carnelian story an envoy from the Mithridate Office can offer you intelligence. If you pass the Watchful check, you can listen to what he says and ignore all of it in spite of it all sounding very believable. Until they mention the tiger's affinity for flame. You write down this one piece of accurate information, and the envoy realises you've not been paying him no attention - you've just worked out that everything else he told you was a lie. He then stutters, shuts up, and leaves.
President Eden has one of these moments if you tell him you know his self-destruct code. He thinks you're bluffing. Your character then casually rattles it off. His (more or less) last words consist of a horrified and almost heartbreaking "Oh! Oh... my."
Sarah Lyons: Take cover! BEHEMOTH!!!
The raiders have rather amusing Oh, Crap! moments should you toss a grenade their way. Or reverse pick pocketing-placing a grenade or land mine in their inventory instead of taking it out frequently followed with them noticing and exploding after yelling "fuck me" and "holy shit"-also they will jump up go rigid and then fall apart into arms and legs its a very odd explosion
Benny gets one in which confronting him about trying to kill you early-game and stealing the Platinum Chip, he sends you up to the Presidental Suite for a "chat" which turns into him ambushing you with four of his goons. After you kill them, this exchange can take place on the intercomm:
Benny: The cleaners will knock twice. Make sure they're thorough.
The Courier: Yeah, it's a real mess up here - four bodies.
Benny: What the fuck?
General Lee Oliver gets one of these at the Battle Of Hoover Dam when the walls fall down to reveal your army of upgraded Securitrons standing right behind him. Even better is if after you talk him down into simply retreating, in which he boast about how if he were in your shoes he would personally see you hang, this exchange can happen.
Courier:"I see. Yes Man, please throw General Oliver from the Dam."
Oliver:"What the hell? No, get away from me, you goddamn TV on wheels!"
With the "Terrifying Presence" Perk, sometimes the Courier simply has to announce who they are, in order to provide this reaction.
Old World Blues. Decide you aren't having the Think Tank's crap anymore. Watch as they spend the entirety of the fight crapping their tanks in fear while fumbling with their weapons.
Klein: A... FIGHT? I... I'VE NEVER BEEN IN A FIGHT. WHAT... UH, WHAT, WHAT, WHAT DO I... AIIGGHGHH! COLLEAGUES! THINK TANK! ALERT! ALERT! WE ARE UNDER ATTACK!
The Bullet Time effect associated with V.A.T.S. kills in all three of the Bethesda games has a chance of combining this with Slow "NO!": enemies will occasionally moan "oooooo shiiiiit" as they die.
Done rather marvelously in Final Fantasy V; after repeatedly failing to save the other crystals your party finally reaches a crystal that didn't shatter shortly after their arrival. Galuf finally recovers his memory, and is reunited with his granddaughter, Cara/Krile. Then Lenna/Reina and Faris are reunited with their father, King Tycoon. So the crystal's secure and three of the party members were reunited with their loved ones... Things are looking up now, right? WRONG. After the final crystal shatters anyway, giving the entire group a huge wake-up call, and the Big Bad Exdeath makes his grand entrance, ominous entry scene, Leitmotif of Doom, Evil Gloating, and Evil Laugh in all their full glory. Bartz muttering "Shit!" as the entire scene quickly goes downhill doesn't even touch how much of an Oh, Crap! moment this was.
Cid gets one (his cigarette even falls out of his mouth) when the WEAPONS are flying out of the Northern Crater from the deck of the Highwind.
Sephiroth is probably responsible for causing half of these moments within the game itself, be it when he makes an appearance, does something horrible, or when the heroes discover the aftermath of something that got in his way.
Cloud: [upon discovering the impaled body of a giant Zolom] "Did Sephiroth...do this?"
The look on Black Waltz No.3's face when he realizes that he's accidentally set his own airship on fire — just before he crashes into the South Gate.
Queen Brahne's horrified expression a split second before Bahamut incinerates her ship.
Kuja, upon realizing that Garland has arrived in the Invincible.
Hades is the second-hardest optional boss in the game. However, Ozma, the hardest, can be fought and defeated before you even meet Hades. Do so, and Hades has one of these moments right before the battle begins.
In Final Fantasy XIII, the look on your party's faces when Galenth Dysley reveals himself to be the fal'Cie Barthandelus is this trope in its purest essence. For the first time in the entire game, all six of them are visibly terrified, and considering some of the crap they've already been through up to this point, that's saying a lot.
In Fire Emblem: Radiant Dawn, the Goddess of Order, Ashera, has turned all the world to stone and only your party and her chosen warriors sent to kill you are not. This isn't the Oh Crap moment though. That would be when Yune, the Goddess of Chaos goes to recruit more allies to your cause... And finds that Goldoa, land of the Dragons, and home to the single strongest and oldest living hero in the world, is completely empty... Tibarn says it best:
Tibarn:If you're saying what I think you're saying, then we could have a very big problem. Lots of very big problems.
In Fire Emblem Fates, "Endless Nightmare" is this trope in musical form, playing whenever a unit is about to be killed; a very unpleasant proposition when one can be Killed Off for Real. It also plays during Birthright chapter 26 when Xander puts the Avatar on the ropes at the start of their Duel to the Death, and during Conquest chapter 25 when Ryoma, tricked into believing that the Avatar killed Hinoka, attacks them and challenges them to a Duel to the Death.
It takes a massive fleet-wide effort to coordinate the weakening and eventual destruction of the Shivan juggernaut Sathanas, culminating in an epic slugfest between the Not Quite DeadSathanas and the GTVA Colossus. In your tiny fighter, you can only watch the titans slug it out, until the Colossus emerges - Battered, but victorious. And then another, fresh Sathanas warps right in on top of the remains of the old one. Through a Subspace Jump Node that you had already collapsed. And more are on the way.
Lt. Snipes has one later on, which he helpfully passes on to the player. "DIVE DIVE DIVE! HIT YOUR BURNERS PILOT!" And then you just barely dodge a speeding, screen-filling juggernaut jumping out just as you jump in. If you try to dodge in any direction except down as he tells you, your tiny little fighter will be crushed like a tin can in a trash compacter.
Poor Prince Eonia in Galaxy Angel when he sees the light of the Chrono Break Cannon comming toward him all he can do is stand up and look horrified. Oh crap indeed.
In Geist, one of the possible death sounds for the standard soldiers.
Everyone Kratos meets and kills. Hell, that's everyone Kratos meets.
At the very end of God of War II, as Zeus is rallying his brothers and telling them that they can win the fight against this one mortal, there is a tremor. Then another. The marble bust of Zeus cracks, and its head falls to the floor, and shatters. The gods rush to the balcony, and the look of pure fear on Zeus's face at what he can see is intensely satisfying. The Titans, as strong as they were in the height of the great war, climbing their mountain, and on Gaia's shoulder, Kratos, the Blade of Olympus in hand and bloodlust on his mind. THE PROPHECY SHALL BE FULFILLED!!! AH HAH HAH HAH HAH!
The Lost Age has one at the end. Alex is at the top of Mt. Aleph as the Golden Sun rises, preparing to receive godlike power. Then, The Wise One shows up and explains how Alex's plan was doomed from the start. Alex is quite upset.
Guilty Gear: Nearly every character in Dizzy's Instant Kill in Revelator. In short, Dizzy (a gentle girl who dislikes fighting) narrowly saves her opponent being a massive beam fired by Necro, a demonic entity who possesses one of her wings. The beam just misses and causes an explosive blast which forms a towering mushroom cloud behind the opponent, who turns to the camera with an expression which screams this. Sol gets Hidden Eyes, Sin, Axl, and Elphelt get Shonen-style Blank White Eyes, Chipp just points at the explosion with his jaw dropped in disbelief, and a Mirror Match Dizzy covers her mouth in shock and abject terror.
Whenever you play Through the Fire and Flames on Expert in Guitar Hero 3, there's only two words that greet you on the loading screen: "Good Luck". And that's all they need to say, too. And on 3/25/11 Harmonix announced that it's DLC for RB3, and with PRO GUITAR, no less. Better kiss those hands good-bye.
These happen in Half-Life at random; if you shoot a grenade at the marines, sometimes they'll yell "Oh, shit!". Often times they can't complete their sentence, resulting in a Curse Cut Short. Similarly, snipers in the Half-Life 2 series will sometimes yell "Shit!" before a grenade you've thrown at them goes off.
At the end of the first chapter of Episode Two when you finally see what exactly is "snooping around out here".
When you destroy the barn Advisor's generator, and instead of it dying, the pod opens and the Advisor inside psychically lifts you and Alyx into the air, immobilizing you so effectively that you can't even raise your weapon.
You're leisurely driving past the White Forest Inn, when suddenly your cat smashes into a Combine forcefield. "It's a trap!"
The final Strider battle at the end of Episode Two:
MIRT: Looks like that was the last one! [beat] ...Wait a minute.
In the final scene of Episode Two, when you start seeing flashes of light as you enter the helicopter hangar.
That's one of the possible reactions of a Combine sniper in Half-Life 2, after you toss a grenade in his hideout. Also, in Episode 2, you have to defend a room with four entrance tunnels, each has 3 warning lights that go off when antlions are coming through a tunnel to attack, indicating the amount by the number of lights. For most of the fight, you have to move your two auto-turrets and the two rebels assisting you to a new tunnel to defend. Then your Vortigaunt allies arrive and on all four tunnels all three lights light up. The music of the scene turns it into one of the greatest moments in the whole game series.
The discovery of Delta Halo in Halo 2. The look (and reaction) of Johnson says it all.
In the first cutscene of Halo: Combat Evolved's "Assault on the Control Room" level ("I Would Have Been Your Daddy..."), a Grunt guard, who has been checking up on his napping buddies, runs away shrieking as Foehammer's Pelican suddenly emerges from the control room air shaft.
Haunting Ground has many but two of the most notable include Fiona taking a wrong step in a certain puzzle one too many times sees a crossbow fired at her direction that shows her giving this expression before it being implied going through her eye, another is hiding in a furnace from Daniella and Daniella both knows you are there and knows how to use said furnace...
In Heavy Rain, Norman has one in the "Case Closed" ending, when he sees tiny virtual tanks running around on his desk, but then he realizes, Oh, Crap!! He's not wearing the glasses! He's actually probably insane now! Fade to black. This is also what Lt. Blake would react when Madison get pasts his roadblocks in "The Old Warehouse".
In Horizon Forbidden West, Aloy has this moment, when she visits Thebes, which is Ted Faro's personal bunker, in the ruins of San Francisco. The reason? She later uses her Focus to check the map of the facility... And she later sees a giant red growth that is covering the entire reactor room. To her utter horror, Aloy realises that this red growth is none other than Ted Faro, who has been alive but severely mutated into an unrecognisable Meat Moss after centuries of isolation, due to an uncontrollable cell mutation. Even Ceo, an obsequious follower of Ted, could only look at disgust of what was once Ted Faro. Not to mention, the fleshy sounds he made when Ceo went inside.
In the sequel, when Cole first fights the Behemoth.
In the second game's DLC "Festival of Blood" ending, Zeke reacted like this when he realised the lady hes been sharing the whole vampire story with was actually one herself.
Zeke: "Aw shit..."
Also when Zeke and Cole see the Beast survive a nuke to the face, only to explode in their faces, then continue his rampage.
Green Arrow does this twice in Injustice: Gods Among Us. Once when Green Lantern is knocked out by the door that's blown off its hinges by Killer Frost, and again when Green Arrow is grabbed by Solomon Grundy. Both times, he says, "Oh, shit!"
Veger has this look on his face near the end of Jak 3: Wastelander, right when he puts two and two together: He was bathed in a light that would turn him into a Precursor... Precursors are ottsels... therefore, he will be turned into an— POINK!
The part in Jak X: Combat Racing, when Jak realizes Jak's weapons aren't working. In the middle of a race. One can only imagine Daxter's reaction.
Kerbal Space Program provides handy visual feeds of your kerbonauts on the corner of the screen, and while the cowardly ones will probably scream the entire trip, the braver ones will stay calm until something goes horribly, horribly wrong. It also occurs in the "Kerbal Space Program 1.0 Launch" promotional video.
In Killing Floor, this happens way more than one would expect. Whenever you see a Flesh Pound and, to a lesser extent, the Scrake. Then after you defeat all 10 waves, here comes Patriarch. "WHAT HAVE YOU DONE TO MY CHILDREN?" and "EVERYTHING"S EASIER WHEN YOU HAVE A ROCKET LAUNCHER FOR AN ARM." In fact, when the Patriarch cloaks, it's the eye of the storm. You wait. He could come at any second. Will he go for you or your team mates? I don't know if I can-OH GOD HE SPAWNED RIGHT IN FRONT OF ME I'M DEAD.
In Killzone 3, the Big Bad has an epic one after you fire a nuke at his flagship:
Xehanort/Ansem in Kingdom Hearts had a good laugh in the final battle about the naïve little kid, who was trying to tell him, that there was light behind his beloved Door to Darkness. He, however, stopped laughing as soon as the aforementioned door unleashed a massive load of pure light against him, leaving him shouting: "LIGHT? But-Butwhy?" as he realizes that he's about to be destroyed by the very thing he has been hunting for the past decade.
Master Xehanort in Kingdom Hearts: Birth by Sleep is extremely smug throughout the entire game, except for one part at the end. After committing Grand Theft Me on Terra, Xehanort walks off only to be attacked by Terra's Animated Armor that has come to life out of his utter hatred for Xehanort.
Terra-Xehanort: "Your body submits, your heart succumbs — so why does your mind RESIST?"
Mickey: Gee, do you really think it's possible that Xehanort could have planned things that far in advance? Yen Sid: No, as a matter of fact, I do not. [...] Even Xehanort cannot transport his body across vast reaches of time. Mickey: Oh... oh no! Xehanort did give up his body! It was a version of him that was possessing Riku! Yen Sid: [eyes widen in horror] No! It cannot be!
The Platinum Cup in Kingdom Heartsdefinitely counts. For those familiar with the Final Fantasy series, they'll assuredly be wondering just what foe awaits in the Platinum Cup, for those unaware, the "Platinum" in "Platinum Cup" is quite the clear giveaway, for once Sora arrives, he witness a strange magical phenomenon occur, and once it concludes the back of a certain well-known someone is shown, as well as a certain unmistakable singular wing on said back... Those that know the Final Fantasy series well enough will clearly know who it is from the back alone, for the opponent Sora fights is none other than freakin' Sephiroth himself...! For first-timers that know this character, this'll set off quite the few internal alarms, for very good reason...
In Kingdoms of Amalur: Reckoning, Gadflow's eyes widen and his mouth falls open in shock and terror when he finally sees his "goddess" Tirnoch for the first time in the flesh. He likely wasn't expecting Tirnoch to be a gigantic and fearsome dragon.
In Kirby Super Star Ultra, the intro to Milky Way Wishes explains, "In this game, Kirby can't copy the abilities of his enemies!" His reaction◊ is hilarious to behold.
When the characters of Kirby's Return to Dream Land learn that Magolor has been manipulating them the entire time to obtain the Master Crown from Landia, at which point he dons it and becomes incredibly powerful, Dedede's face is priceless.
Dedede wears the same expression again in Kirby: Triple Deluxe when Queen Sectonia makes her entrance, before proceeding to use Kirby as a shield.
Happens in Kirby: Planet Robobot when he sees the Access Ark descending upon Popstar in the opening cutscene. Also done collectively by the Dedede clones in a fourth-wall breaking manner when they realize the D3 cannon they're riding is about to blow.
In the finale of the Dead Air campaign in Left 4 Dead, the survivors see an airplane approaching the airport extremely low. Said airplane crashes into the ground, breaks into many pieces, and basically explodes upon impact. The survivors basically go "holy shit..." upon seeing the crash.
During the intro trailer, right after the survivors make it through a rather clingy horde of infected and into an elevator, Ellis' face mirrors despair and fear, as he exclaims "Holy shit!". The camera pans out to show the big Zombie-infested hall into which they're descending.
The Tank and Witch have survivors get extremely nervous if they encounter them; a Witch can instantly incapacitate a survivor in one hit while a Tank can send survivors flying in a single punch and can also send large objects like cars and dumpsters flying at them.
Halfway through the third map of The Parish campaign, the survivors run into a car lot whose cars are all alarmed. The survivors go quiet upon seeing it and warn each other to watch their aim. All it takes is one stray bullet to hit a car, which will set the alarm off and alert the horde.
Legacy of a Thousand Suns: The flavor text for the tactic "Killing Field" reads "The best part is the look on their faces when they realize they're doomed..."
Moebius spends the entirety of the series as the Smug Snake to end all Smug Snakes. Being The Omniscient, he can see that all his schemes are going to work, and if Kain or Raziel try to stop him, he can give the former a heart attack with his staff, and disable the latter's Reaver. That is, until Kain comes back from the dead... again. Moebius is completely caught off guard, and since Kain's heart was ripped out, he has absolutely no way to stop him. The look on Moebius' face the whole time is priceless.
Kain: First your omniscience, and now your powers. You're slipping badly.
Kain gets one himself in Defiance: after having lived thousands of years, and spent most of those years plotting and snarking, he's left nearly speechless when Raziel allows himself to be absorbed by the Soul Reaver, allowing him to see the Elder God. Just realizing what his true enemy is, and what he sentenced Raziel to when he killed him, gives Kain the only dumbfounded look we've ever seen cross his face. Then, he gets angry...
Moebius' reaction to Kain's revival and newfound immunity to his power pales in comparison to his sheer horror when he finally sees the true horrifying form of the Elder God.
Ganondorf does this in The Legend of Zelda: Twilight Princess right after he realizes that the Triforce of Power, which had saved him the first time he had been impaled isn't working anymore. As well as when he dies when he sees a maskless Zant (probably as a near-death hallucination), who kills him bysnapping his own friggin' neck!
Link gets one in the same game when he finishes off Morpheel, gets warped to Lanayru Spring, turns around, and...walks right into Zant. Right after that, Midna gets one right before getting hit with a blast of light from Lanayru.
Link has quite a few of these moments in The Wind Waker. The first of them is when he is about to be literally catapulted to the interior of Forsaken Fortress. The second is when he retrieves his sword in said fortress but then he gets trapped in a small battle arena where he has to fight a Bokoblin. The third is when Ganondorf tells him that the Master Sword lost its power.
Even the Helmaroc King has one. During the beginning of the game, Tetra's crew catapults multiple boulders at him from their ship as he flies away, because he kidnapped Tetra. After several misses, the King looks back at the ship, causing his beak to open wide, because he realizes that a boulder is about to smack him in the face. It does.
Tatl has one in The Legend of Zelda: Majora's Mask. After defeating the Skull Kid, she starts going on about how much of an idiot he was. An offscreen voice agrees with her, and she emphatically continues, thinking it's the Skull Kid coming to his senses, until she realizes it's Majora's Mask — the thing she basically thought was just an accessory — that is speaking. She may be a glowing ball of light, but you just know that if she had a visible face, it would have a major Oh Crap expression.
Even Link has one in Majora's Mask once the Gibdo Man makes an appearance.
Before the final boss in The Legend of Zelda: Ocarina of Time, Link watches the King of Evil he seemingly killed transform into a gigantic monster called Ganon, which then proceeds to knock the only weapon capable of killing it out of Link's hands to land outside the ring of fire surrounding the battlefield. In addition, this moment is one of maybe three times that Link's facial expression changes from that determined frown.
In The Legend of Zelda: Skyward Sword, Link has a priceless reaction when, in the midst of his skydive down to the surface, he realizes that Groose is diving after him - without anything to use as a parachute.
In Life: the Game, some of the losing endings have the player character make an 'uh-oh' face before the game over message.
Lord Monarch: In story mode in sega version emotions can be often seen in dialogues, especially when they feel awful or something bad happens. In gameplay, every kings have their face shown as status. They get worried or surprised if their energy is low.
Episode 3 in Lost Planet 2 is just about full of these moments. Especially near the end just after you've escaped a town infested with both a massive amount of snipers and some medium-huge akrid on train, you meet another MUCH BIGGER train with a pretty massive railway-gun on it. Then when you board it your train gets rocket'd. Then after you've successfully killed every last Snow Pirate on the enemy train, the biggest Akrid you've seen up to that point (a humongous worm that actually ate your first train) comes rushing in from the back, wanting to eat this train as well. The moment it emerges from the sand is really just... "Oh Crap!" And THEN you kill it and find that your hometown has been covered under snow because an even bigger akrid (seriously, this thing's a MOUNTAIN!) has absorbed all the heat in the area... Yeah...
In addition to featuring similar bytes for bonus bosses and high level monsters, Luminous Arc features -strategic- Oh Craps. The characters will inform you, in varying shades of worry, if the enemy is going to do something nasty on its turn, and ignoring their warnings can quickly lead to disaster.
Aya has one during a flashback in the True Ending, when we revisit an earlier exchange of Father and Maria's.
Father: ...She is my most precious... Doll of them all.
Aya gets it even worse when she sees another flashback, this time of Father burying a knife in Mother's chest. And this all culminates with the biggest Oh, Crap! of all; after this information is revealed to Aya, she wakes up... right beside Father.
Every falling scene in the Mario & Luigi series. The reactions on the Bros.'s faces are just priceless in all of them. Also, every time Mario and Luigi come across a boss. Luigi just freaks out instantly.
Against the bosses sometimes as well. The reaction of Midbus and minions in Bowser's Castle when Bowser nearly throws it halfway across the kingdom is priceless. As is the reaction of the Monty Moles driving the Fawful Express after seeing Bowser's massive eyes through the windscreen.
In contrast, when Midbus is roasted by giant Bowser, he reacts in an unimpressed deadpan manner.
Mario and Dreambert's reaction in Mario & Luigi: Dream Team when they realise the living version of Mount Pajamaja is about to ram them at about 90 miles per hour. Of course, it's pretty likely near anyone else would react the same way to that situation.
Mass Effect has several of these strewn across the games.
The most notable being Shepard's expression when debris of Sovereign comes flying into the tower.
If you tell the Fifth Fleet not to save the Destiny Ascension, but to focus on Sovereign, the asari commander of the Ascension gets one of these when the Alliance stops answering their hails.
Saren has a little one on Ilos, when he sees the Normandy swooping in and the Mako flying towards him.
The neutral conversation choice when warning Rana that you're about to nuke the facility has a priceless reaction.
Shepard I'm gonna blow this place to hell and gone. If you want to make it out alive, you'd better start running. Rana: What!? You can't- But I'll never- Ah! [runs] Garrus: You enjoyed that, Commander.
During Miranda's loyalty mission, you have an opportunity to pull off a Renegade interrupt while facing off against a group of Eclipse mercenaries. It involves Shepard casually snapping the neck of the mercenary squad's commander, Miranda gunning down the man's second and a couple of his buddies, and Shepard shooting a well-placed crane carrying an explosive crate that wipes out most of the rest of the squad. The only surviving mercenary is a shocked salarian with a priceless "holy shit!" look on his face.
Also, the Collector General at the end of the second game. The ending cinematic has it looking around with an expression of sorrow and fear as Harbinger releases control and the base begins to explode around it. If an expressionless bug alien could make an Oh, Crap! face, that would be it.
Garrus uses this word for word during his loyalty mission when a pair of YMIR mechs arrive on the scene. And again during the mission on Sur'Kesh during Mass Effect 3. Shepards opens a door to an elevator, and finds a bomb inside. Garrus invokes this trope by name while the party backs away.
Mouse's reaction on discovering that both Thane and Shepard are standing behind him. Immediately lampshaded when Thane informs Mouse that he can change his pants afterwards.
If Ronald Taylor is abandoned by his would-be rescuers and left to face the consequences of almost a decade of exploitation, he's wearing this expression... just before the first of the hunters jumps him.
Near the end of ME2, when the Collectors board the Normandy, Joker's lines throughout the entire mission to give EDI control of the Normandy and throw the Collectors out the airlock consist almost entirely of "Shit, shit, shit, shit!!!"
A bit further in, when the Normandy SR-2 makes the jump through the Omega-4 Relay to hit the Collector Base, Joker lets out a perfect "Oh, shit!" as the instant the ship comes out of FTL there's a massive wall of starship debris right there in the ship's immediate path.
Major Coats' face says it all in the teaser for Mass Effect 3 as he's hit with a Reaper spotlight. Cue a rapid pan out above London to see not a single but eight Reapers descending on the city.
Lampshaded in the Overlord DLC, when the satellite dish comes crumbling down on Shepard & Co's heads, in a moment that manages to radiate this trope even when wearing, for example, the Blood Dragon armour (which conceals Shepard's entire head). As Shepard put it...
She gets over it quickly, but Tela Vasir in "Lair of the Shadow Broker" was genuinely expecting Shepard, particularly a Paragon Shepard, and his/her squadmates to put their weapons down for the sake of her hostage. She's visibly taken aback when this doesn't happen. Even if it's a bluff, it provides a window to hit Tela from behind with a table. Not that it slows her down all that much.
There's one in the Arrival DLC. Some people get the jump on Shepard, then pump him/her full of sedatives. Unfortunately for them, Shepard's cybernetic implants also grant 'em Acquired Poison Immunity, and the base personnel are horrified to discover that they have to increase the dosage every couple of hours just to keep Shepard under. Eventually the sedatives stop working altogether and s/he wakes up pissed. One scientist sees this and gets absolutely terrified, especially once s/he punches out both guards in the room effortlessly.
Scientist: Oh shit, the sedatives aren't working. SECURITY!!!
Shepard has one when s/he sees Object Rho, and begins to realize what's actually going on.
Shepard: You have the Reaper artifact just sitting here? Out in the open?! Kenson...this is not good.
Later on, a lone mook has a particularly good one.
Project Guard: I have Shepard stuck in the vents, s/he's not going anywhere. *Sees Shepard* SHEPARD'S OUT! GET ME SOME BACKUP!
In the multiplayer mode for Mass Effect 3, the Cerberus troops shout "Krogan!" when they see one charging into melee range. As well as such gems as "They're horrible!" and the Combat Engineer's panicked "I need support!" - or the frantic squawking of the Nemesis. Hard to blame them, considering that the N7 Special Ops. routinely face odds that Shepard only ever faces in the endgame of each title. Another common one however is on Reaper maps, when allied forces will nervously yell "BANSHEE!" after hearing that high-pitched scream in the distance. Or a quarian male's or volus' nervous cry of "Geth Prime!" when being played as by someone else.
Halfway through being converted into another Banshee husk, Rila reveals that she's holding the detonator to a bomb... and she's just pressed the trigger. Cue an open-mouthed gape of horror from the Banshee that was converting her; yep, Rila just made a husk feel fear!
During the Mars mission in Mass Effect 3, Shepard meets a group of Cerberus troops that are clearly aware of Shepard's reputation. Even more impressive since we later discover they are heavily indoctrinated and can barely think for themselves, meaning that Shepard literally is so terrifying even indoctrination isn't enough to stop the fear of them!
Trooper: HOLY SHIT! IT'S SHEPARD!!
On the final Rannoch mission, you are dispatched to blow up a Reaper broadcasting device. You use a targeting laser to call in the Normandy for an airstrike, and then you find out that you just woke up a Reaper. Then the Reaper has a subtle one after Shepard defeats it by charging at it on foot.
Shepard: You know who I am?
Reaper: Harbinger speaks of you.
When Kai Leng tells his gunship to "target the supports" of the temple on Thessia, Shepard gets a full-bodyOh, Crap! moment, drawing up his/her gun, backing away and then trying to make a run for it.
How many times does Shepard get this? Well in a romance with Garrus the Citadel DLC has him drag her onto the dance floor. The entire galaxy knows Shepard can't dance, and when he does she looks terrified.
Shepard gets another one during the final mission on Earth, just as it seems they've cleared out all obstacles, Anderson gets a communique that Harbinger is on the way... personally. Shepard's tone of voice when responding to this has a general, resigned sound of "Well, shit."
You get to take another turn causing these reactions in your enemies in the Citadel DLC. The CAT-6 mooks you're fighting crap their pants when they realise that your force contains (depending on survival rates in past games and the DLC you've installed) a Memetic Badass vigilante, a krogan battlemaster, and even potentially a Prothean, and their boss doesn't expect them to survive, just slow you down. Also, because they're jamming messages so you can't contact help, they can't contact help, either. Gets even more satisfying when they realize that all of these other people barely register as nuisances, much less threats when compared to Shepard.
CAT-6 Merc #1: Why did s/he say "Slow him/her down"? We're allowed to kill Shepard if we have to, right?
CAT-6 Merc #2: S/he said slow him/her down because s/he thinks we're cannon fodder.
CAT-6 Merc #1: Oh. Well, shit.
On the other side of that DLC, a number of your teammates — most notably Garrus and Vega — get this reaction should EDI be accompanying you to reclaim the Normandy, causing her to be temporarily shut down when the villains shut down her shipboard processor.
There's a beautiful Oh, Crap! moment in the teaser trailer for MechWarrior 5. Its 3015, and the view-point character is piloting a Warhammer, which is a good, solid, heavy mech, but not the biggest. After taking down a light Jenner mech with little effort by collapsing the building it was standing on, the viewpoint character rushes into the ensuing dust cloud, not noticing some movement on the other side of the cloud. A few seconds in, the Warhammer stops on account of having run into something. Staring down a wall of unrecognizable metal, the pilot pans the camera up...and realizes he's staring up at a skull-faced Atlas, which is the single biggest baddest Mech of the era and fully capable of taking him to pieces. It does. The Warhammer pilot ejects after being brutalized, his mech's computer warning of critical damage to internal systems. The pilot's Ejection Seat launches him straight up, and his parachute brings him straight down. He looks down just in time to see his Mech's ammo bays explode below him.
On the other hand the bird's eye view from the probe he launched seconds earlier clearly shows two mechs and its fairly obvious that the Atlas was one of the scary heavyweight assault mechs, the skull face itself is visible, so the Oh, Crap! is a result of the pilot forgetting about the second mech and not recognising the largest mass-produced humanoid chassis in the Battletech timeline. Too Dumb to Live most definitely.
In a Call-Back to the MechWarrior 3 intro (see below), the Atlas pilot realizes too late that the 'Mech he'd just wasted is about to go critical right in his face. He already has his 'Mech in full reverse by the time the Warhammer pilot looks back down.
Opening cinematic for the first MechCommander. Light squad of Inner Sphere mechs is scouting an urban environment, when out steps a Clan Mad Cat — a 75-ton assault machine somehow undetected by the Raven scout mech whose entire purpose is sensor recon. The Mad Cat pilot wastes no time, disposing of the second-heaviest IS mech with his first barrage. Commands from overhead result in everybody except the Raven pilot running for their lives, as the MechCommander's superiors watch in confusion. The Raven is instructed to GET THE MAD CAT'S ATTENTION. The Raven pilot follows orders and unleashes his scout mech's weapons against the Mad Cat, a move that does almost nothing except piss off the Mad Cat pilot, which turns to face him. Cue background-stretching perspective shot and, "...I've got his attention, sir..." as the Raven pilot realizes he's staring down the guns of a Mech that is double his weight, almost as fast, and had already effortlessly wiped out one teammate. The MechCommander leads the Raven into a dead end while fleeing the pursuing Mad Cat. It was a distraction to give the rest of the squad a chance for tactical movement and a clear shot at the Mad Cat's back. The Mad Cat falls for it, tunneling on pursuing the Raven and getting shot in the back before he can deliver a coup de grace. Of course, a well-trained Clanner would have been slow to remember that while Clanners like samurai-style duels, Spheroids are Combat Pragmatists.
MechWarrior 3 provides a couple on both sides for its introduction. For the Inner Sphere, there's Ground Commander watching one of their Firefly Mechs go down in a single shot and the Atlas pilot's reaction to the Mad CatGoing Critical. For the Clan Smoke Jaguar Mechs, the aforementioned Atlas showing up out of nowhere to surprise the Mad Cat and the realization that there's two-score missiles coming straight for your cockpit for the Thor.
MechWarrior 2 had two particularly notable ones. The first was from the intro to Ghost Bear's Legacy. A Vulture, a 60 ton Clan mech that's geared for skirmishing at long range, is marching through a barren snowfield and sends a radio message informing his base that there's nothing out there. Then he picks up a heat signature but can't tell where it is. The snow drift directly in front of him suddenly explodes, revealing a massive mech, at which point the Vulture pilot screams "Kodiak, base, Kodiak!" and when told that reinforcements are en route responds with "neg, base, I need reinforcements NOW!!!" In the intro to Mechwarrior 2: Mercenaries, your commanding officer has one when she's heading back to your dropship only to hear the dropship captain say that he's getting the hell out of there and see the dropship's door begin to close as the ship blasts off for space. She shouts that she needs more time, but the dropship captain tells her that she's out of time because he's not getting paid enough to die.
Mega Man Zero: Zero actually has a subtle tone of panic in his voice when he believes he's going up against multiple enemies at once: like when the remaining three Guardians decided to face him together near the end of Zero 1, or his first encounter with the Einherjar Eight and Commander Craft in Zero 4.
Raiden in Metal Gear Solid 2: Sons of Liberty gets an "Oh, crap" moment himself when he encounters Fortune, a terrorist that can't be shot due to bullets being manipulated to wiz by her and grenades that turn into duds if used against her. She also carries a powerful railgun.
The Blue X in Metroid Fusion manage to pull this off despite being amorphous blobs with only one animation — since the Metroid Vaccine makes Samus weak to cold, the supercold Blue X attack her by forcing her to absorb them, freezing her from within. After she acquires the Varia Suit, this no longer works, but the X only realize that after seeing it fail a few times. Once they catch on, they'll stop doing that, halting mid-charge if they have to, and flee from her for the rest of the game.
Done hilariously in Metroid Prime 2: Echoes, where you can find Pirate logs detailing an ill-fated expedition. The logs end with them panicking about the destroyed stealth field and two Samuses.
Pirate Log: Horrific as it may sound, there are two of them now. We are bracing for a new assault.
In Metroid Prime 3: Corruption, a Space Pirate log details how they inadvertently brought the remains of Dark Samus with them while hastily collecting Phazon on Aether. Dark Samus then revives herself in their cargo hold...
Misao: If you choose to sacrifice the wrong person, you end up being transported back to the real world with the killer. You see the chain of events leading to Misao's murder, and Aki is left with the murderer before her. It only gets worse when the killer realises that Aki saw the flashbacks too, and now knows everything.
In multiplayer, scoring 25 kills in a single life will give you the Tactical Nuke killstreak. When it's deployed, the normally calm and collected announcers will scream that a nuke is inbound. Even the Task Force 141 announcer is noticeably panicked. It's up to you to imagine the looks on their faces.
TACTICAL NUKE, INCOMING!!!
You essentially get the same effect if the enemy should ever get an AC-130. The announcers tend to be calm and focused for most of the match until either a nuke or AC-130 appears. Especially the Spetsnaz announcer. Listen for yourself.
There's also one instance during the campaign: When Price boards the Russian submarine all by himself and launches an ICBM, all that Ghost can do is helplessly scream "CODE BLACK! CODE BLACK!!!" into the radio.
Your hunter will literally flinch when spotted for the first time by a large monster, accompanied by some fitting music (heard here at around 1:09) and an eye icon that changes from yellow to red (monster spotted you to monster has targeted you respectively). And some of the larger monsters will roar so loud your screen blurs.
In Monster Hunter 3 (Tri), the quest "Guts: It's What's For Dinner" has the player hunting Epioth for the titular Monster Guts, only to run into the Lagiacrus; and in 3 Ultimate an early High Rank quest has the player find a Great Jaggi being crushed by a Deviljho. Both times, the Guild Sweetheart panics over the monsters' presence and tells you to get away from them immediately.note The Lagiacrus is indestructible even if you somehow survive against it for a long time, while the Deviljho is a magnitude more powerful than the High Rank monsters you'll be facing in the near future.
Zigzagged in a game of "Oh Crap Hot Potato" between the enemies and the player the end of Salsa's chapter. After a grueling battle you manage to actually take down the enemy's Pork Tank and the Pork Troopers realize maybe picking a fight with you was a bad idea. But then three more Pork Tanks show up and they start advancing again. But then Lucas shows up with a baby Drago, the same baby Drago who's mother the Pork Troopers turned into a chimera, and he calls for help. Cue satisfying as all hell beat down while their entire force gets torn apart by the enraged father.
Lisa gets this reaction in the bathroom when she sees two more Augers approaching her after mistaking the third one for Megan, and realizes that they're about to drain her blood.
In the 2017 edition, if you let the Auger tackle Danny for the laser gun while another Auger puts the blood extractor device behind his neck, he quickly turns around to see the device clamp itself on his throat, and he gets this "Oh, Crap!" look as the device turns on while trying to free himself, knowing that its drill will soon bore itself into his throat and its vacuum will drain his blood...
Ninja Gaiden: Ryu Hayabusa's Oh Crap moments in the Original Trilogy is summed up in two words: "What the...?!" The Angry Video Game Nerd even lampshades this in his review of Ninja Gaiden.
AVGN: "What was he gonna say? 'What the fuck?!'"
Oh Shit! for the MSX, one of the laziest Pac-Man ripoffs ever made, had a digitized voice saying the game's title whenever the player lost a life.
You can tell this is exactly what is going through Orochi's head after Susano removes his other seven in Ōkami.
In Paper Mario 64, starting at Chapter 4 and up, there are numerous occasions where Mooks will absolutely freak out upon seeing you while they guard an important location, some of which yell out up front that they don't stand a chance.
Dallas's reaction to the Dentist knowing his true identity has him dart his eyes back and forth before trying to get up from the chair to escape, only to be restrained by the Dentist and the nurse.
In-game, the gang sometimes give one of these when calling out Special Units - usually when spotting a Bulldozer. Wolf is downright terrified of Cloakers, while Clover is terrified of EVERY special unit.
Quite a bit of Enemy Chatter consists of this, especially when they realize who they're fighting. They also have responses for certain player actions, such as deploying medical and ammunition bags, and especially killing enemies with the OVE-900 Saw.
SWAT Officer: We aren't prepared for this, that's the Payday Gang! FBI Officer: He just killed somebody, WITH A SAW!
And before an escape sequence, your getaway driver will likely scream one of these right before he crashes into something and dies.
The Meltdown heist has a memorable one from Bain himself, as soon as he finds out what exactly the "valuable cargo" Vlad wanted them to rob for him was.
Bain: Is that... a nuclear warhead!? I... don't... look, just grab it. Carefully! Vlad, are you CRAZY!? NUKES!?
"WHISCASH's Anticipation made it shudder!" (This means at least one opponent has an attacking move that's super effective against it.)
Ghetsis in Black/White expresses his eagerness to see the look on your face when you've lost all hope. Unfortunately, you can neither wish him likewise nor get a good look at his face when you stomp his fancy hax dragon into so much paste on the floor, along with his plot to Take Over the World.
Also, in Pokemon Shuffle, version 1.2.0 has the Super Catch Mode. If a Pokemon breaks free, and if the Great Ball fails, you have to replay the stage to try to catch the Pokemon again, but manage to get 2,500 coins for the Great Ball, and you may get a massive 25% boost in the catch rate, and the percentage will be gray. Thus, the Pokemon that you are trying to catch will sweat, knowing that it is completely screwed.
In Portal 2, Wheatley gets one right before GLaDOS zings him into space. Literally.
The defective turrets have a lot of quotes of this nature that are uttered prior to or as they're being launched into the incinerator after failing to pass the voice testing segment of quality control. Some of them even try to imitate the functional turrets, which goes about as well as one might expect:
Turret: Hello. Hello. Hell-aw, crap.
In the Prince of Persia series, enemies generally have some variant of this expression in the last moments of the game before the Reset Button is pressed.
Karen: You know what he can do? He'll kill me! (thump) Oh my God. Oh my God, he's here! He's in the building! Alex: (transforming) I know. (Fade to Black)
Prototype, having as it basically does The Thing (1982) as a protagonist, inspires this trope a lot: Alex walks up behind Doctor McMullen and says cheerily (for him, anyway), "Hey, boss." The good doctor falls right out of his chair in horror.
"Oh shiiit!!" The last words of many a Marine right before Alex digs in.
Alex lets himself drop an "Oh shit," when his cover is blown at a Blackwatch briefing due to Bloodtox.
In The Punisher, during the final level in Ryker's Island, Punisher goes down to death row and find a guy named Ronnie the Ripper who killed a bunch of housewives in '91. Since Punisher isn't wearing his iconic skull, the man doesn't know who he is and asks to be set free in exchange for knowledge of weapons. Punisher does so, and the man asks who he is, and freaks out once Punisher says "Frank Castle". Punisher can then proceed to strap him in the electric chair to torture him for info and kill him if the player desires.
In the early Puyo Puyo games (including Kirby's Avalanche and Dr. Robotnik's Mean Bean Machine), there is a mugshot of your opponent on screen. As their well starts to fill up, their expression will usually turn into one of panic or frustration. They'll start sweating and then flash when they're near defeat. The games also try to invoke this on the player when their well fills up, as the opponent's mugshot will become very smug and the music will change to something more frantic.
Ratchet & Clank: Up Your Arsenal features Ratchet showing identical "we're dead" expressions upon a) discovering that Captain Qwark, their last hope, thinks he's a monkey, and b) when Clank turns out to have been replaced by an evil duplicate, who promptly grows to 30 feet tall and attacks him.
The final boss of Ratchet & Clank Future: Tools of Destruction. After the first phase, Tachyon's basically gone insane, and the Dimensionator has ripped open a hole in space and sent our eponymous duo and the Big Bad to some random asteroid in the middle of space, leaving no chance for escape. The only option is going on with the fight.
Rayman 3: Hoodlum Havoc. When you defeat Reflux's third form by shooting him in the power crystal embedded in his back with a missile, causing him to plummet back down to the arena, Rayman does the usual victory pose, blows a raspberry at the now unoccupied air in front of him, and two seconds later, Reflux simply floats back up unharmed.
In Red Dead Redemption, a random encounter has Marston coming upon two men working with dynamite and surrounded by barrels marked TNT. When Marston gets close, one of the men will exclaim to the other "Time for a cigar. Got a light?" Marston gives no remarks a second before the camp and the two men disappear.
Late in Red Dead Redemption II, Colm O'Driscoll, a mortal nemesis of Dutch and his gang, is arrested and sentenced to hang. This is actually the third time he has been condemned, and he is very confident it will be the third time he will escape. When he sees that Dutch and Sadie have left two of his would-be saviors indisposed, and that Arthur has taken care of his sharpshooter, his confidence wavers and he is left on the verge of tears as he realizes he is going to die.
In Resident Evil: The Darkside Chronicles, during the Resident Evil Code: Veronica segment, Claire and Steve pass through a prison ward where the bunks are full of bloody corpses. They wind up around the corner at a dead end and, after getting attacked by a zombie who bursts in through the window, prepare to leave the ward, only to find that the bunks are now empty.
In Rockman 4 Minus Infinity, Shadow Man's reaction in Wily Stage 4 when his smoke bomb (that he used to cover his escape every other time) fails to go off. To rub salt into the wound, it then does go off moments after he explodes.
A similar scene occurs earlier in the game when you run into your first Beheaded Kamikaze. After gunning it down, Sam says "AAAAAAAAHHHH yourself!" Cue the sound of many Beheaded Kamikazes screaming in unison. "Uh-oh."
The iconic first Kamikaze encounter is paid homage to in Serious Sam 3: BFE in the first level, Summer in Cairo. A single Kamikaze appears from the dry grass in front of the museum surroundings where the helicopter ruins are located. Sam blows it up and remarks "AAAAAAHHH, put a sock in it!". Then comes a marching band of Kamikazes. "Uh-oh."
The final boss of the first game causes this reaction to the Exposition Fairy, who advises you to "Run and pray!"
Angels in Shin Megami Tensei III: Nocturne have a shocked "NO WAY!" reaction when you kill them, which rather nicely compliments the smug look on their faces prior to you kicking their ass. Bonus points for the "NO WAY!" being uttered in a shocked tone that indicates getting the crap beaten out of them was something they thought impossible.
During Scenario 30 in the Space Route in Shin Super Robot Wars, Dr. Hell and Baron Ashura get this reaction when they are about to be destroyed by the SRX. They also wonder if Zechs Merquise can provide some backup.
In Soul Sunder this is Alex's reaction to him and his sister Arya ending up outside the protection of their village and therefore subject to random monster attacks.
The VGA remake of Space Quest, if you get caught by the Orat, Roger will scream "OH NOOOOO!" before the Orat squashes him into a human basketball and dribbles him.
Space Quest 6, if you walk off the edge of a broken bridge, Roger will say "Whoops!" before he falls to his death.
In Space Station 13 on the Goonstation branch, looking at a black hole or loose singularity yields the flavor text "FUCK FUCK FUCK AAAHHH". Being on fire also causes your HUD to say "OH FUCK FIRE FIRE FIRE OH GOD AAAAAAA" when checking your body temperature.
Spider-Man: Web of Shadows: Spidey has just planted bombs in key locations on a S.H.I.E.L.D. Helicarrier infested with symbiotes. Suddenly huge, black, oily tentacles grab the ship:
Spidey: Ohhhhhhh boy.
In a similar vein, in Ultimate Spider-Man, Spidey is chasing after the Rhino. When he first comes across the trail of destruction, he knows that fighting the Rhino is going to suck ("Ooooh, this hurts already."). When he meets the Rhino, who in this continuity is a 15-foot tall robotic armor-tank?
Spidey: Hey, is that a rhino suit, or are you just happy to see... (Rhino turns around and stands up to his full height) ...I am so scared I can't even finish my lame joke.
J. Jonah Jameson has a big one in Spider-Man (PS4) during the postgame of Silver Liningwhen Miles becomes a second Spider-Man.
J.J.: JARED! CALL MY DOCTOR AND DOUBLE ALL MY PRESCRIPTIONS!!!
In Spirits of Anglerwood Forest, Edgar gets one when his parents in Angler's Maw turn out to be fake. He gets another one right after when Ezra first reveals himself.
In Spore, this is one of the animations that creatures can do, and EVERYONE RUNS IN SHEER PANIC whenever there is a meteor storm or a UFO.
In Star Control II, the Ur-Quan have a pretty bad one when you tell them you were in contact with a sentient talking pet. These guys conquered almost the entire universe including Earth and control the scariest and deadliest fleet, but they are scared shitless when you tell them. (Their reaction is justified.)
Ur-Quan:If what you say is true, you were in contact with a creature so horrible, so evil, that is makes ANYTHING else you have ever known TRIVIAL by comparison. There is no equal to the Dnyarri's cruelty; to its love for torment. Dying a THOUSAND TIMES would be preferable to what is in store for you if we do not stop that creature.
From an early scene where two Terransoldiers hit what they think is a dog with a jeep.
Lester: Looks liak yew mashed sum powr fella's dowg, Sarge. Sarge: It's a Zerglin', Lester. Smaller taip'uh Zerg. They woun't be owt this far unleyess... owwww sheyat. (Hydralisks proceed to disembowel the two men off screen)
Towards the end of Brood War, Zeratul's discovery of the hybrid.
The Zoness stage involves the Sarumarine boss, which has two big side-mounted cannons, and a crane to retrieve them when they get shot off. Obviously, the designers intend for you to to shoot the cannons and then Oh, Crap! out when the crane rolls into action. But if you're smart enough to shoot the crane, you get a priceless "Ohh, shoot!!!" from the Sarumarine's captain, proving that Gosh Dang It to Heck!does work if you ham it up enough.
The Star Ocean series features this in the sound bytes for each character at the start of a battle. Against an enemy that outmatch your level sufficiently, the general consensus is barely restrained panic. (Dias from Second Story averts this forever, and even inspires it himself sometimes. This is because Dias is Dias.)
Star Wars Jedi: Fallen Order has a huge one near the end, where Cere has seemingly gotten through to her former Padawan Trilla, who has become the Second Sister, and is on the verge of abandoning her hatred for her former master. But then Trilla's ears pick up the sound of ominous rasping breathing coming up from right behind her and she takes on a look of utter, gut-wrenching terror, just before Darth Vader himself shows up.
When your character unleashes an Ultra Combo, your opponent will get a seriously scared look on his/her face right before the first blow connects.
Newcomer Rufus yells this out verbatim when he gets knocked out with anything harder than a jab.
In the full introduction movie (not whats on the game CD), Gouken does this after giving what seems to be a knockout blow to Akuma, only to have him warp behind him and unleash the Raging Demon. Especially funny when you see the timing of the actions matched up with the lyrics: Akuma recovers into the RD just as the lead is saying "My spirit's in-de-struc-ti-ble," followed up by one long "Ooohhhhhhhhh" as Gouken eats the attack. You can almost add the crap yourself.
Also, any Super Combo or Ultra Combo KO is sure to make anyone exclaim this... especially if it's a counter-move and the finishing move is inevitable.
Both Mario and Petey Piranha in Super Mario Sunshine express an "oh crap" moment in Episode 2 of Bianca Hills when the top of the windmill they're standing on starts to crack before giving way and making them fall down. Despite the fact that Petey has no visible eyes, you can still tell that he knows he's screwed before he and Mario take the plunge.
Hariet of the Broodals in Super Mario Odyssey. When you knock off her hat (her only defense against your attacks), she reaches up to her head and freaks out a bit when she realizes she's not wearing it.
Super Robot Wars: Original Generation 2. Mission 32. One of the best ideas on that mission is to make absolutely sure you do not trigger the reinforcements on the enemy phase. The fact that the reinforcements contain five bosses amongst them AND everyone takes damage during the cutscene makes that good advice to take. There's even more Oh, Crap! for everyone in the closing moments of the chapter, to boot.
Likewise, in Mission 30 of Super Robot Wars W: Leaving the Junk Guild ship too far behind is a bad thing, which you find out when, halfway during the battle, a large ZAFT force shows up behind you. A dozen GINNs with bazookas are not good for the health of a simple salvage ship.
In Super Robot Wars Z 3, AG has a hilarious one when after revealing he is the Edel Bernel and thus responsible for many of the miseries leading up to Z3, he sees that the entirety of Z-BLUE is pissed and receives a collective beat-down from them.
Luke gets the Big Bad back via defeating him not once but twice, the second time when the Big Bad had access to the power of the resident god...which wasn't enough to prevent Luke killing him.
Tales of Vesperia has two in succession. First the Big Bad's reaction when he realizes he didn't activate a superweapon but, power down a barrier holding back an Eldritch Abomination. Then there is Yuri's reaction to being stabbed by Sodia and then falling off of Zaude and into the ocean, almost certainly to his death.
A whammer of a one happens, in an understated way, in Tales of Xillia. Though Milla only shows a minor bit of shock at it, the fact The Stoic just freaked out over Exodus slamming into an invisible barrier, which summons a bunch of freaking airships into a world that was more standard fantasy before says whole volumes at just how fucked the cast is now.
"Meet the Demoman" includes a fairly accurate rendition of an in-game encounter with a skilled Demoman, culminating in about a dozen sticky bombs hidden on one side of a door frame, and the sudden (but not quite sudden enough) realization that the Demoman is, indeed, a grim bloody fable with an unhappy bloody end.
There's another use of this in "Meet the Spy", just before the climax...
Soldier: "Alright. Who's ready to go find this spy?" Spy: "Right behind you."
There's also Meet the Sandvich, where we get an entirely verbal version-as the visual of the scene focuses on the Sandvich.
Soldier: He's getting away, don't let him get to the fridge! DO NOT DO IT... Scout: Don't do it pal, uh... Heavy: Omm nom nom nom ahheheheh Soldier:: Ohhh, Hell Scout: Ohhh...hey, uh, calm down there, you listening, uhh OH GOD! OMIGODOMIGODOMI— *CRUNCHWHUNCH*\\ ''My blood! He punched out all my blood!!
Recorded but unused is a line for the Scout, which is meant to be played when taking damage while trying to use his Bonk! Atomic Punch. Said line is this trope verbatim, delivered with the scout's usual humorous lack of restraint. One that is used, added during the 2012 Halloween update:
Scout:"Haha, you got a bomb on your head....OH CRAP I GOT A BOMB ON MY HEAD!"
Mann vs Machine has several of these for the mercenaries to say, when a particularly nasty bot is coming.
Heavy: "METAL GIANT!"
Heavy takes a break to take a bite out of his sandvich, when all of a sudden a "teammate" appears out of thin air in the corner of the room, and he freaks out.
Go to Helltower, wait until the bridge appears, snatch up one of the rare spells, and toss it in the middle of a fray. Everyone will freak out.
Both the Engineer and Medic, when they find out Soldier has spent the last three days teleporting bread.
Thief II: The Metal Age: Father Karras has a plan to cover the world in gas that dissolves living matter while he stays sealed in an air-tight chamber. He didn't expect Garrett to turn the plan back on itself and pump the stuff into his hideout. The close-up lingers just long enough to catch his expression changing.
One of the Achievements for The Consigliere (a Mafia role that can investigate one person per night to discover their role) in Town of Salem is called "Uh Oh", and is awarded for discovering a Veteran. The Veteran is a town role that can go on alert at night, killing anyone who visits them. If you investigate a Veteran, there is a decent chance that he's on alert and killed you for the trouble.
Nrvnqsr in Tsukihime was already having a tough time of it in his fight against Shiki, but was far more annoyed than afraid... until Arcueid mentioned that "Oh, by the way, I forgot to tell you this, but Shiki even killed me once." Nrvnqsr's reaction is priceless. And the protagonist (and, at the time, Roa) is subject to one of these. See: To the Pain.
Nathan Drake has this almost as his catchphrase. He says it, or some variation, every five minutes. Either that, or he's so far beyond panic that he gets irritated at the insurmountable odds stacked against him.
Nate: (after encountering bad guys while being shot at by a military helicopter) Can't you guys see the helicopter?! I have enough shit to deal with!
If Drake falls from a high place to his death, he will occassionally shout out "Oh Shiiiiittttt!!!!!"
Toriel gives one of these for a split frame if you somehow manage to get her to accidentally kill you during your battle with her.
Flowey gives one at the end of the Genocide route as part of a monologue that essentially boils down to "We get along so well. I mean, just look at us; we're both remorseless mass-murderers who wouldn't hestitate to... kill... each other... oh no..."
This is actually invoked at the end with Sans toward the player. His line after dodging your first attack is this:
Alphys gets one near the end of the Pacifist Route. Upon asking Papyrus why he gathered everyone up at New Home, he replies "A tiny flower told me." Said tiny flower is Flowey, who Alphys is responsible for creating, and she has just enough time to look appropriately horrified before the final boss shows up.
Lee, the main protagonist of The Walking Dead game has a few of these, but probably the most dramatic is when Lilly puts her gun between Carley's eyes and pulls the trigger, especially if you'd been supporting Lilly up until that point.
Wario: (Wario is typing on his computer.) We make the games! I make the money! All the money! (The viruses appear.) Huh? What's going on!? (The Mega Bug lunges towards the game's screen, and Wario pisses himself and throws his game at the wall.)
The Quarter Knights in Wild ARMs have one when Mother reveals her true intentions. Apparently, they didn't count on their leader being an Omnicidal Maniac.
At one point in Wing Alliance, the player accidentally flies into a secret Imperial weapons testing ground guarded by four Star Destroyers, none of which are happy to see you. It gets better if the player is familiar with the wider Expanded Universe: the destroyers are all future members of Thrawn's fleet, and the lead ship is none other than the Chimaera, his future flagship.
In Wing Commander IV, the Vesuvius (a carrier with guns to engage capships directly, as well as attacking them with its fighters) is almost ready to the jump to Sol System, with the Intrepid chasing it. When the Vesuvius turns around to engage the Intrepid, it's Blair's turn for the Oh, Crap! face.
In the prologue chapter of The Witcher 2: Assassins of Kings, hero Geralt is the personal bodyguard of King Foltest, who had been targeted by an assassin shortly after a rival king had been murdered as well. Geralt keeps some discreet distance as the king talks to the hooded monk who had protected his children during the battle, but turns around as Geralt comes charging into the room, sword in hand. As the monks dagger is coming at his throat, the kings face has just a moment to say "Oh Crap, he's Right Behind Me, isn't he?"
In The Witcher 3: Wild Hunt, at the conclusion of the quest "Reason of State", Radovid is clearly scared out of his mind when, while fleeing his would-be assassins, he opens a door to find himself face to face with Phillipa Eilhart.
In the expansion Wrath of the Lich King is one in-game video available after a quest line, in which Arthas manages to kill Saurfang the Younger and is about to kill Bolvar. But then the Forsaken appear, with Arthas saying just one word ("Sylvanas...") in a real Oh Crap voice before getting his ass kicked and retreating.
Relatedly but less dramatically, in the official trailer for Patch 3.1, you can tell this is what Jaina's thinking when she sees that Thrall and Garrosh are going to arrive before Varian Wrynn has left.
Cataclysm has one in the Goblin starting area. The Goblin captain and navigator are piloting Trade Prince Gallywix's slave ship, and get lost in a fog; when the fog clears, they find they've steered right into the middle of an Alliance-Horde naval battle.
This basically sums up Thrall's reaction in Rise of the Horde that the draenei, the orcs' old neighbors-turned-enemies who they nearly made extinct, have arrived on Azeroth and joined the Alliance.
In the finale of Cataclysm, when Thrall gets ready to use the Dragon Soul to blast Deathwing we get a brief but satisfying close-up of Deathwing's eye widening in panic as he recognizes the Artifact of Doomhe created — he knows all too well just how badly the thing can screw him over.
In Reign of Chaos, one mission has Arthas and Jaina track down a shipment of tainted grain that turns those who eat it into zombies. Then this happens:
Arthas: Wait... What did those crates contain? Footman:Just a shipment of grain from Andorhal. There's no need to worry milord, it's already been distributed amongst the villagers. Arthas: Oh no... -Cue small-scale Zombie Apocalypse and Hold the Line mission-
In Yu-Gi-Oh! Reshef of Destruction, it takes 2 Millennium Items to revive a God Card's power. Once you get six, you think that things will be good, right? Nope. The Gods return to stone after that.
