** The whole Orieni Empire had one when they learned the Centauri have just invented the [[spoiler: mass driver, the setting's way to deliver a ColonyDrop]]. Given what happens when the Centauri finally drive back the Orieni and invade their space, it's {{Justified}}. Even if the first hint of the [[spoiler: mass driver's]] existence hadn't been [[spoiler: a world having its geography rearranged]].
*** Also, the ship discovering of its existence has a ''massive'' one when they do, because they also realize ''the Centauri ship mounting that weapon is aiming it at them''.

Considering the guy was a Dungeon Keeper, and the souls of Dungeon Keepers go to the Realms of the Dark Gods when they are killed or their Dungeon Hearts are destroyed, him coming back after having been physically killed is a major reversal moment. Of course, he was [[AGodAmI in the process of making himself a god prior to his physical death]].

--> But then I noticed that the gang leader wasn't looking at me. His gaze was, very, very slowly, turning upwards. That was when we heard a snort behind us. I noticed that I'd been backed into the rock in the middle of the clearing.
--> ''[[ThatsNoMoon It was]] [[HollywoodChameleons not a]] [[TyrannosaurusRex rock.]]''
** Also from Chapter 31: Kari, when [[spoiler:Velociripper breaks into her house.]] Then Terrordactyl when a bunch of ''Kronosaurus'' turn up in the middle of the harbor fight. Then Splashdown upon seeing [[spoiler:Ludlow's]] army.
** Chapter 34: Helen actually utters the trope name upon seeing [[spoiler: GlaDOS.]] Everyone else is quick to join in the MassOhCrap moment [[spoiler: until Neo reveals that he managed to [[HeelFaceTurn turn the robot around.]]]] Then [[spoiler:Sarah and Dash get this when the HMS Bubonic Plague blows up, and Adam when Ripper reveals himself to be NotQuiteDead. And Ripper himself only has enough time to let out a BigNo when he is finally KilledOffForReal.]]
** Chapter 35: First Sarah, then Adam let out an anguished BigWordShout when they think that [[spoiler:Violet has been killed off. And in the end, Ludlow lets out "a long, loud, high-pitched, piercing scream of complete and absolute terror" before and while he really ''is'' [[KilledOffForReal killed off.]]]]

-->'''Yushari''': ''(gulps)'' "Yours."
-->'''Narrator''': Ami-Chan slowly looked up in horror. True to Yushari-San's word, the 120mm smoothbore L/44 gun of the Type-90 was pointed directly at the Type-74. There was no doubt an APFSDS round was already loaded in the gun breech.

Of course he’s alive. It was an act of utter optimism for me to have even dreamed otherwise. I must have taken leave of my senses, I can’t imagine what I was thinking. Just because someone said that his body was found burned to a crisp, I can’t imagine why I would have thought he was dead. Clearly I have much left to learn about the art of proper pessimism.”]]

After spending the entire fic as a prisoner, with a badly derailed Fluttershy attempting to MindRape her into an infantile state, Rainbow Dash messes her diaper and is so terrified by the situation that her will breaks and she starts believing herself to be Fluttershy's baby (this was later retconned into being the effects of a mental regression drug Fluttershy created, since it generally takes more than an afternoon to totally shatter someone's will).

[[folder: ''Video Game/Streets Of Rage'' ]]

* Plenty of these abound within ''Fanfic/StreetsOfRageSaga'', but the crowning one (as of this writing) has to be during the epilogue of the fourth story in the series, ''The New Syndicate'': TheSyndicate has kidnapped and attempted to mind-wipe [[spoiler:Blaze]]. It seems to have worked at first [[spoiler:since she can't recall her name or any of her past memories when asked]]...but they weren't counting on hearing anything contrary mere minutes later. So cue the man in charge turning pale when he hears this line:
--> ''My name is [[spoiler:Blaze]], [[CrowningMomentOfAwesome and I remember everything]]''.

* Many people in ''Fanfic/WithStringsAttached'' have these:
** The cop in New Zork freaks out when Paul breaks the handcuffs that were supposed to have neutralized his SuperStrength.
** The Hunter stands in stunned amazement when John lifts the river.
** [[spoiler: Grunnel]] has one when he realizes that Paul isn't mind-controlled after all.
** There is a collective one amongst the Raleka and skahs wizards when Sapsa hits Paul with an enormous burst of flame, and Paul says, [[NowItsMyTurn “That was lovely! Do it again!”]]
** When Shag and Varx reveal to Jeft that they'd told the real Dalns gods what was going on. “Did you want gods pissed at you, Jeft?”

* The READERS of ''FanFic/ImperfectMetamorphosis'' get one when they realise that TheFourthWallWillNotProtectYou from Yuuka anymore. Here's the moment of realisation:
--> [[spoiler: [[FourthWallObserver "Or to be specific, I may converse with you, the you that's watching behind your eyes]]."]]
--> [[spoiler: [[BreakingTheFourthWall With that, she smiles, looks you directly in the eye, and smiles at you]].]]
--> [[spoiler: [[OhCrap Yes]].]]
--> [[spoiler: [[ParanoiaFuel You]].]]
--> [[spoiler: [[TheFourthWallWillNotProtectYou "Hello dears," Yuuka says sweetly. "Enjoying the story?]]"]]
* The fan comic "[[http://danbooru.donmai.us/pool/show/3881 Let's Play Resident Evil]]" has quite a few of these moments, [[http://danbooru.donmai.us/post/show/967327 most of them involving Ran]].

[[folder: ''Film/Tron'' ]]

* ''Fanfic/ThroughADiamondSky'' has a couple. A minor one is when the leader of the Iso colony is being rude and realizes that the visitor asking questions isn't Clu, but Flynn himself. The second, larger, one is when a {{Mook}} realizes that they just made the fatal error of trying to kill ''Tron.''

* The reaction of the entire "Wargods" strike force and the ''player'' when [[spoiler:the GTD ''Imperieuse'' jumps in just as the Wargods were on the cusp of victory against the GTD ''Carthage'', fully-armed and fresh, and outgunning all of the remaining Wargods ships ''combined''.]] Things go [[EverybodysDeadDave downhill]] from there.
