Poncho: Bullshit. You ain't afraid of no man.
Billy: There's something out there, hunting us... and it ain't no man. You're all gonna die.
- The very idea of being hunted by an invisible alien who is tougher than Arnold Schwarzenegger.
- The Predator in general. Besides its delightful face, it can camouflage itself, making it near invisible (unless water comes into play), mimic human voices to lure victims and collects human skulls and spines as trophies. Not to mention, it has quite the array of frightening roars, screams and clicking noises.
- The skinned bloodied corpses of Jim Hopper and his men. Accompanied by a Scare Chord and a Jump Scare.
- The distorted recordings of Billy's laugh and Mac's voice ("Over here", "turn around", "anytime").
- When Hawkins is killed by The Predator. It moves in swiftly and kills him, spilling blood all over the female refugee. All that his crew members could locate of Hawkins through a blood trail. The Audience don't see much thankfully but Body Horror and Squick can't even begin to describe it.Poncho: Major, you better take a look at this.
Dutch: Did you find Hawkins?
Poncho: I-I can't tell.
Dutch: (eyes widen)
- The part where the Predator steals Blaine's body and a boar it scared jumps on Mac in a panic.
- Also, the Fridge Horror that comes into play after the team discovers Blaine's body is missing - if that boar hadn't been there and been freaked out, they never would have known the Predator was there.
- Could even be that the Predator deliberately flushed the boar towards the team as a distraction, which gives a creepy indicator of how cunning the Predator really is.
- Dillion searches for Mac, only to find him dead. Suddenly he hears Mac behind him ("anytime"), causing him to quickly turn around. Dillion looks around up on the trees (we see from his point of view), with Predator's cackles echoing. As he's looking, you can just make out the Predator's invisible silhouette standing on the branch which Dillion looked past before looking at it again. This time the silhouette is more obvious, with glowing eyes, which Dillion sees with widen eyes.
- The scene where Dutch ends up careening off a waterfall and falls into the pool of water below to escape the Predator, and the Predator follows him. Dutch emerges above water, and is able to catch his breath in a few moments of silence...and then the Predator falls into the pool a few yards behind him, complete with a Scare Chord. And since the Predator is still using its invisibility camouflage at this point, we still don't see the Predator proper when it hits the water—just the resulting splash, which makes the water look like it rose upwards by itself. It's no surprise that Dutch upon hearing the splash immediately starts swimming towards land, with an absolutely terrified expression.
- A sort of reveal after Mac dies: the laser beam's convergence at the Predator's shoulder mount gives viewers the impression it shot Mac from quite a distance... then it moves, and we see that it was literally standing right on top of him.
- The Predator's laugh when it activates the self-destruction mechanism to kill itself. It starts out deep and slow, then suddenly bursts into a high, loud, very human-like maniacal cackle which mimics Billy's laugh.
- While waiting for the Predator to fall into their trap, Anna starts talking about something that happened in her childhood:Anna: "When I was little, we found a man. He looked like... like, butchered. The old woman in the village crossed themselves... and whispered crazy things - strange things. El Diablo cazador de hombres. Only in the hottest years this happens - and this year, it grows hot. We begin finding our men. We found them sometimes without their skins... and sometimes much, much worse. ...El caza trofeos de los hombres means the demon who makes trophies of men."
- The camera focuses on Dutch, who looks at her with curiosity and confusion.
- Dutch is a big guy, and throughout the film we see him perform nearly superhuman feats of strength. In the final act of the film, where he and the Jungle Hunter are having a fist fight, the Predator outclasses him on every level. All those feats of strength were to showcase just how far beyond humans the Predators are.
- Not long after this, Dutch emerges from the team's hiding place, ostensibly to bait the Predator into their trap. He carefully navigates the network of snares and tripwires, even getting momentarily stuck on one, as he moves from cover into the open. He stands there a moment, staring into the jungle, and sees no sign of the creature. Just as he starts to turn around, a snare is triggered and with an awful roar the Predator flies into the air, hoisted by the net.
- The Jump Scare alone is bad enough, but Fridge Horror comes into play once you consider that in order to have triggered that trap the Predator must have been standing right behind Dutch, totally invisible, about to stab him in the back.
- The Fridge Horror gets even worse the more you think about it. Did it creep between Dutch and the rest of the team completely undetected? How long was it there for? Was it standing there in front of them, invisible, the entire time and Dutch walked right past it?
- The Killers over in the comics. Take a Predator and remove all forms of honor like not killing those that can't fight back and limiting their tech to make things even. They also use Xenomorphs as hunting dogs.
- During operations in Iraq, a unit of U.S. Marines used the Predator's laugh as a psyops tool while clearing a section of Fallujah, by blasting it across the city over loudspeakers. This backfired, because the Marines actually going door-to-door in the city got so weirded out that they radioed back to request that the recording be turned off.
