 * This kobold, facing the swarm of adventurers coming from the tavern.
 * Another quite literal instance from Belkar, as he stands defenseless before Miko.
 * Even within the limits of being a skeleton drawn with stick-figure art, Xykon's expression when he's confronted by in this strip conveys this reaction loud and clear. Later in the same battle, it happens again, after.
 * "OK, so I've got bad news, and I've got bad news."
 * Belkar Bitterleaf, though a hero (arguably), suffers one in #568..
 * Elan, Therkla, and Qarr share one in the second-to-last panel of this strip.

"Sniper: So why didn't you become a group leader? West: Don't know. They basically just asked my kill count. Sniper: Your kill count? *Beat* Oh. My. God!"
 * Vaarsuvius is like this here, which begins a series of escalating Oh Crap moments on the following pages, until...

"Ennesby: Low-yield kinetic strike to the fore dorsal turret ... Hull-breach above the wardroom! Kevyn: Wait, dorsal turret access is right up there. We're in the wardroom."
 * The assassin #2 on the train, who unfortunately for himself didn't walk in via the door and thus could not be simply duped into leaving before he sees anything unusual. "Uh.. Uh oh..."
 * You could make a drinking game for all these moments in Schlock Mercenary.
 * Ably demonstrated in the fourth panel of this strip.
 * Not even being harm incarnate is defense against an Oh Crap moment.
 * "Heh. It looks like all you did was take a hullcutter to the barrels." (The barrels being in large part, the heavily computerized weapon's circuitboard.)
 * And used with the appropriate sentence here.
 * One from Tagon.
 * Although the tension is deflated a moment later, Kevyn suffers this in Book 6, Part IV, after Ennesby gives a damage report.

 * Kevyn here, on account of an incoming tank.
 * One from "San Asimov's Finest"
 * And in this one.
 * Maxim 3: An ordnance technician at a dead run outranks everybody.
 * A twofer in the last row of this comic. Even if it's just a still picture, the target's last view of an oncoming missile is never happy.
 * Malott here.
 * After Schlock delivered a message to Breya, she thinks about what this may mean... and then makes a face. Which she didn't after finding out that explosion reduced a police officer to spray paint and scattered Schlock's pieces around.

"Regina: (thinking) Should be easy. I nearly pulped him last time we fought. I mean, it's been what, six years? What could he have learned in that time? Dan: I learned to hear thoughts. Among other things. Regina: (thinking) OK. New plan. Piddle self. Run."

When the fated day came when a fox got stuck in her home village's food supply, she snapped its neck in order to spite her fate, and saved the tail as a memento. That's not the Prophecy Twist resulting in her Oh Crap moment...
 * In the webcomic Narbonic, this becomes Dave's normal state of being becomes one big Oh Crap moment.
 * Dan and Mab's Furry Adventures has its share of Oh Crap moments, particularly in the latest arc. One of the better ones has to be Regina's, starting on page 973. Of course, this being DMFA, it's the page's punchline.
 * K-shnk! K-shnk!*

"Charlie: That was clever though, right? Parson: Sure. Determining the decision not to spend all the calculations. Cost: one calculation. Charlie: ) Parson: Teaching me that my bracer can make sophisticated predictions about the future? Priceless. Charlie: ... ("
 * And like many such moments, it doubles as a Crowning Moment of Funny
 * The Adventures of Dr. McNinja:
 * King Radical, when he hears about Dr. McNinja's new motorcycle.
 * It's very subtle, but the last panel of this page is an excellent example.
 * Gordito gets a big one in the second-to-last panel when he realizes his Badass Mustache is useless against the principal... and he's going to have to shave it.

 * Hanna Is Not a Boy's Name has its share of these moments, as Conrad demonstrates.

 * Jacob Deegan gets this little moment. Also an occurance of Precision F-Strike.
 * Also, Dominic himself, when facing down the Beast.
 * Captain SNES has a nice one from Gades when the protagonist, Alex, launches his side of a very, very short Beam-O-War match, which didn't last very long (and neither did Gades). Alex's beam was much bigger.
 * If Ed had had a face in this strip of Megatokyo, it would have had this expression.
 * Erfworld: Charlie has the distinction of getting one offscreen during this exchange with Parson over the Eyebooks, after just getting Parson to use one of the calculations he owed Charlie to assess whether it was worth giving up the rest of the calculations in exchange for information from Parson.

"Black Mage: Teeth... like daggers... eyes... also like daggers... Fighter: How does that work? Thief: Piercing gaze? Fighter: You're on fire today! Black Mage: Scales noticeably dagger-like..."
 * Later on, pretty much all of Gobwin Knob (especially Stanley and Wanda, who had been unshakable beforehand) get this when.
 * In 8-Bit Theater... well they happen a lot. But the best may come here, when the ultimate Jerkass discovers he's finally bitten off more than he can chew.
 * This classic, when Black Mage sees Muffin:

"Faye: All right! We're well and truly fucked. Martin: And not the fun, slightly sticky kind of fucked! Faye: That was TERRIBLE. Martin: YOU try being funny when your life is flashing before your eyes!"
 * Each character gets at least one, but Black Mage, as the resident Chew Toy gets the most of them. It doesn't help him that his face is EASILY the best suited for these expressions.
 * A minor one in El Goonish Shive: Nanase uses her fairy doll to contact Ellen, and tries to wake her up by tickling her nose with her tail. Her reaction when she realises she's about to get messily sneezed on is hilarious.
 * There's a slightly more major one here. More of an awkward "oh crap" than a dangerous one, but just as expressive...
 * Another awkward example is Elliot's reaction to Noah bringing up his parents' death.
 * Justin here, when George reveals that he knows that Elliot is Cheerleadra, if he's wrong on a few minor details.

 * In Slightly Damned, the latest villain to cross the heroes' path gets a short one when Kieri slices his bow in half.
 * In VG Cats, Aeris finds out the hard way that Coach is controlled by a completely different type of bot...
 * Ctrl+Alt+Del. The look on 1's face here just says it all.
 * The girls in Questionable Content have this moment when.

Bun-bun's multi-part switchblade scythe of doom: KA-CLIKITY CLICK KLAK Father Time: 2003: "Would you quit narrating this?""
 * More recently, in strip 1689, Faye's expression in the last panel.
 * Mieville the cat's reaction to Hannalore's attempt at a smile. Odds are that most people would react the same way the cat did.
 * In Fake News Rumble, Jon gets one in his fight with  Seen here.
 * From Casey and Andy: "This has 'bad day' written all over it."
 * Sluggy Freelance:
 * The Anthropomorphic Personification of the year 2003, when facing Bun-bun with the combined powers of the embodiments of nearly all holidays.

""CRapK.""
 * Earlier in the same story we have a scene where a Thanksgiving turkey medic finds out that what appeared to be another turkey is in fact a monster that steals other people's face and hands (in this case wings), being ridden by Bun-bun. She's so shocked she lays an egg while still staring at them.
 * Isp and Osp, when they think the third party of the composite entity they belong to has killed their Demon Lord - and even more so when they find out she failed. "Holy demon-crap!"
 * Jane, an intelligent zombie who's giving Gwynn a "The Reason You Suck" Speech while preparing to eat her brain and mocking her claims of a Tome of Eldritch Lore that gives her magical powers - when she pushes her Berserk Button and finds out that that's what activates said powers, and they're way out of her league. Her face is not shown at the Oh Crap moment; it's instead indicated effectively by her surgical saw winding down.
 * On one occasion, an ordinary, non-talking frog (usual line: "CROAK.") is caught in a building after a somewhat literal-minded One-Man Army has been ordered to kill everyone in it.

"Fernando: Captain, no! An asteroid field is certain death! Open space is bad enough...we can't intentionally fly into debris! Skitter: Wait—why not? Just turn on your doo-dads or shields or whatever. Nosh: What shields? Skitter: Don't you have some kinda...energy bubble that can...I dunno...push aside material or somethin'?...Like a snow-plow? [beat] Skitter: Or some kinda...reinforced hull thingy...that can survive impacts at speeds of...? [beat] Skitter: I'ma skip a step and launch my escape pod now"

 * Sandra is the victim of a Bilingual Backfire here.
 * Zii has a great one in this strip.
 * When Paulus, a wealthy Roman citizen, decides that he's tired of being a bachelor, he has one of his servants put up a personal ad in the Forum. It gets rather more of a response than he expected.
 * Digger: "Meep."
 * In Exterminatus Now, a random paranoid tries to temporarily ingratiate himself in the protagonists so he can hide from "government spooks". The main characters proceed to inform him that those people are likely just foreign businessmen, while revealing enough information to make the guy realize they are government spooks.
 * And here's the reaction of the original team members when Rogue horribly insults Lothar.
 * In Two Evil Scientists, Dr. Wily uses  It works, and he has a few moments to enjoy his success until he realizes
 * In Homestuck, reaction to  is priceless.

 * Let's Destroy The Shagohod!

"Big Boss: Time to head to Grozny Grad? The End: Yeah, how about 'no'. Big Boss: Crap!"
 * Only partial, but still same effect, previously on the same comic:


 * Sees a unique use in this Saturday Morning Breakfast Cereal. (Check the red button; this wouldn't quite count without it.)

 * In Quentyn Quinn, Space Ranger, the Rangers are Oops Boys -- because that's the final words on many a black box.

 * Freefall: "I hate you, Sam. I hate you more than any woman's ever hated a cephalopod."
 * unlike "Eureka!", an "Oh poop!" flash of insight doesn't sound good for the home team.
 * In Romantically Apocalyptic, even an alien-controlled skeleton manages a decent "oh crap" face when he realizes that Mr. Snippy . Then, in the very next strip, Mr. Snippy gets one of his own when, minutes later,.
 * Andy from So...You're a Cartoonist? has one here when he realizes Curmudgeonly Carl will be reviewing his portfolio.

 * In Survivor Fan Characters 's face (last panel - spoilers ahoy!) when she realizes that she should have kept her big fat mouth shut on Season 9.
