History NightmareFuel / TransformersDarkOfTheMoon

** The second time, after Sentinel's FaceHeelTurn and the Decepticon invasion,]] the humans force them to leave Earth. Then Starscream blows up their ship the same way he did Sentinel's. They got better.

** In the novel, Mudflap being shot in the mouth and disintegrating, though he does pummel Sentinel Prime all through this.

** Starscream's death. After chasing down Carly and Sam and finally cornering them, the latter fires Que/Wheeljack's [[GrapplingHookPistol grapple glove]] [[EyeScream into one of the Seeker's optics]]. Starscream flails in agony and tries to escape, but his boosters end up malfunctioning, allowing Sam to [[ColossusClimb climb up the cable]] and stab straight through Starscream's ''other'' optic with a bomb to completely blind him. All the while, [[VillainousBreakdown Starscream thrashes and shrieks like a madman as he claws at his face and tries to fly off]], ultimately ending up on top of a tall building right as the bomb detonates-- [[YourHeadAsplode blowing his head open]] and causing him to fall to the ground and smash to pieces on impact.

** Followed by perhaps the most disturbing scene of the movie. Laserbeak lands in a suburban backyard and transforms into a miniature pink Bumblebee to get close to a little girl, as the page image shows. He says, in the ''creepiest'' voice possible: '''"Is your daddy home?"'''

** The second time, [[spoiler: after Sentinel's FaceHeelTurn and the Decepticon invasion,]] the humans force them to leave Earth. [[spoiler: Then Starscream blows up their ship the same way he did Sentinel's. They got better.]]

** [[spoiler: While that's happening, Optimus tries to fight Sentinel and get some answers from him. Sentinel basically tells him that it is their right to enslave the humans, and that in time, Optimus will come to see things his way. In fact, Sentinel lets Optimus live because he's ''sure it will happen''.]]
*** [[spoiler: The way the sequels went, Sentinel just might have been right...]]

** It starts with the Decepticons lording over the city from the top of a skyscraper. Predictably, SWAT teams show up and start ushering people out. Megatron [[spoiler: (and Sentinel too)]] orders the Decepticon troops to seal off the city. The movie pulls a SmashToBlack. Then we see massive [[AirborneAircraftCarrier Airborne Aircraft Carriers]] launching {{Macross Missile Massacre}}s and smaller fighters, all of which damage the skyline.
** Then it cuts to the ground, where Decepticon {{Mooks}} lay waste to the civilian population. Not a single GoryDiscretionShot to be found. Nope, we see many '''many ''many''''' humans blasted apart onscreen, their bodies reduced to ash and scattered bits of bone, including skulls. [[spoiler: This is repeated when Sam and Epps go to rescue Carly, and are attacked by a Decepticon fighter.]]

*** Then there's Laserbeak's attack on Sam. The only thing allowing him to get away (in the movie, he's more a badass in the adaptations) is the cramped office interior that prevents Laserbeak from flying as fast as he'd like. [[spoiler: That, and the fact that the Decepticons are counting on Sam telling the Autobots about the moon, so they wouldn't suspect the next attack was a diversion.]]
** He gets one last moment before his untimely demise. When Sam goes to rescue Carly [[spoiler: from Dylan's apartment]], Laserbeak is waiting on the wall as a stereo speaker. But the audience never got to see him take on that form, so the moment he transforms and attacks Sam is a bit of surprise. Then he drops Sam over the balcony, making this qualify for ShockingMoments.

--> [[spoiler: '''Dylan''': 'Course, that was back when he was in charge of Budget and Accounting for ''NASA''.]]

* Megatron's face/head. A large chuck of it is missing after the last movie's ending, and inside the wound are a lot of broken mechanisms that ooze reddish-orange Energon. Crawling around in the wound are dozens of tiny insect-like robots that look like Scalpel from the previous film. Whether they're trying to heal his face, or are Cybertronian Maggots living inside a festering wound, is up for debate. [[spoiler: Then Sentinel gouges the wound out further just to remind Megatron who's boss. To clarify, this would be like having a three-inch cylinder of flesh and bone punched out of your forehead, then let it get infected, then let it partially scab over, then have your frenemy tear that scab off with his blunt fingers. ''[[{{Understatement}} Ouch.]]]]''

** [[spoiler: We see later that Mearing was right.]]
* [[spoiler: Sentinel's FaceHeelTurn.]]
** [[spoiler: After the Autobots seemed to risk their lives protecting him from the Decepticons, he reveals himself to be in league with them all along. Just the fact that such a revered Autobot, their ''former leader'', would betray them, is terrifying.]]
** [[spoiler: Then he executes Ironhide. See below for gory details.]]
** [[spoiler: Then he tries to kill Bumblebee, too!]]
*** [[spoiler: In the novelization, the only reason Bumblebee escapes is because [[TheScrappy the Twins]] (Mudflap and Skids for those who have forgotten, or tried to) sacrifice themselves. Skids intercepts the first blast, and has just enough time to lament how he DidntThinkThisThrough to his brother before dying. Then Mudflap, who ''felt'' the death by psychic link, goes AxCrazy and charges Sentinel. It doesn't end well for the smaller Autobot.]]
** [[spoiler: ''And then'' Sentinel attacks the human NEST forces, tearing apart their base and demanding the Spacebridge be returned to him. When Mearing arrives and tries to chew him out, he gives her a nice BadassBoast cum ShutUpKirk speech, before [[NoSell No-Selling]] a rocket launched at him.]]
--> [[spoiler: '''I am a Prime! I do not take orders from ''you''.''']]
** [[spoiler:Sentinel's gun infects his targets with Cosmic Rust, a Cybertronian disease that wastes a Transformer to nothing. The former leader of the Autobots, who instilled Optimus Prime's values of freedom, was more than willing to commit ''war crimes'' even before his FaceHeelTurn.]]
* [[spoiler: Optimus Prime killing Sentinel Prime and Megatron. Notable because he does it ''execution style'', when he's got each of them beat and at his mercy. Optimus Prime has been many things in TF history. An executioner has ''never'' been one of them. In the past, he's always tried to end things peacefully when he's got his enemies at his feet. Not here. Not anymore. The leader of the Autobots can be a terrifying force when he's pushed to his breaking point.]]

[[folder: Family Unfriendly Deaths. Beware unmarked spoilers.]]

*** While they’re saying these lines, the camera is ominously zooming in on a family photo, and the general aura of the scene makes you half expect blood to splatter on the picture any moment.

** [[spoiler: Sentinel’s gun infects his targets with cosmic rust, a Cybertronian disease that wastes a transformer to nothing. The former leader of the Autobots, who instilled Optimus Prime’s values of freedom, was more than willing to commit ''war crimes'' even before his FaceHeelTurn.]]

** Ironhide, ''during'' Sentinel's FaceHeelTurn. Sentinel shoots him '''three fucking times''' with a gun whose ammo is essentially HollywoodAcid rust. The first two shots catch him directly in the back and would be more than enough to kill him. Ironhide pleadingly asks why Sentinel is doing this. The traitorous titan [[PreMortemOneLiner simply responds]], "''I hereby discharge you from duty.''" Then shoots him again. Ironhide's entire body falls in on itself, ''even his head''.

* '''Laserbeak.''' He's a [[NamesToRunAwayFromReallyFast Decepticon]] with [[OmnicidalManiac violent tendencies]] who can [[ParanoiaFuel disguise himself as]] ''[[ParanoiaFuel anything]]'' in seconds. His kill count is no less than 7 in this film, including a pair of innocent Savannah birds.

* This is [[UpToEleven one-upped]] by the Invasion of Chicago. Considering it is a deconstruction of alien invasions in general...

*** [[spoiler: The way the sequel went, plus the promotional material for movie number 5, Sentinel just might have been right...]]
