The Abbott Family
The Abbott family in general
- Action Survivor: Sans their four year old child and the father.
- A Boy, a Girl, and a Baby Family: After losing Beau, the family consists of Regan, Marcus, their parents and a baby that is soon to be born.
- Chekhov's Skill: Before the invasion, the Abbots learned how to speak American Sign Language and taught it to their children in order to communicate with their deaf daughter, Regan. When the invasion started, this played a vital role in ensuring their ability to communicate without drawing the attention of the creatures.
- Crazy-Prepared:
- The nature of their situation demands that the family be extremely cautious about everything they do, and when problems erupt they have a large number of contingencies in place. One in particular involves them creating an underground bunker with a crate and an oxygen mask for their newborn to muffle his cries. Lee and Evelyn end up having one of the few vocal conversations of the film in that bunker, amazed that it worked.
- It even goes as far as mealtimes (eating from place mats with their hands) and board games (using cloth playing pieces and rolling dice on the carpet).
- All the doors in the house are kept open at all times, no doors are opened or closed in the entire movie — since the noise they make would attract attention and keeping them locked would provide absolutely no protection from the monsters' Absurdly Sharp Claws.
- The father (with possible help from his wife) is responsible for the massive lines of sand that the family walks on throughout the film, which connects their house to the nearby town and various other locations, and is even seen filling in a gap with fresh sand. This is likely to reduce the noise they make (and presumably to make it more palatable to walk barefoot on any man-made surfaces that might be encountered).
- Elective Mute: They spend nearly the entire movie communicating only through sign language, not because they can't talk, but in order to prevent blind monsters from hunting them down.
- Good Parents: Both Lee and Evelyn love their children deeply and do the best they can in the worst of circumstances. Evelyn even asks what they are if they can't protect them.
- Guile Hero: The entire family is amazingly resourceful, taking near every precaution to operate without making any notable sounds. Lee in particular is portrayed as almost a Crazy Survivalist, going from meticulously lining their paths with sand to doing radio operations and electronics soldering.
- Happily Married: Evelyn and Lee clearly love one another deeply.
- Homeschooled Kids: Justified, as there wouldn't be a functional school. Evelyn is shown tutoring Marcus in math (a Shakespeare sonnet can also be seen written behind them).
- No Name Given: The family's names were revealed in supplementary materials, but don't appear in the film itself. The baby born and the old man (and wife) aren't named either, likewise, neither is the species of the aliens.
- Too Dumb to Live: Averted — The family doesn't make the standard horror movie mistakes and has prepared for the monsters to attack. Even the unintelligent decisions can be Hand Waved:
- Beau playing with the rocket ship, which leads to his death, is him being too young to understand how serious the entire situation is.
- Evelyn's pregnancy is implied to be unplanned, with the family taking multiple precautions so her labor doesn't alert the monsters. Even if willing to abort the baby, doing it by themselves and without risking major damage to Evelyn would be next to impossible.
- Marcus screaming without covering his mouth after getting his feet stuck in a Bear Trap despite putting the family in further risk in the sequel, because who would resist that much pain without screaming?
- Marcus snooping around in Emmet's place despite the obvious dangers can be seen as him trying to deal with being left alone with the baby and still scared after getting his foot in a Bear Trap.
- Him forgetting to check the vault lock before getting in with the baby. They would've suffocated had Evelyn not got there in time. An alien was chasing them and he wouldn't have time to check without getting slashed.
Evelyn Abbott
Evelyn Abbott
Played By: Emily Blunt
Appearances: A Quiet Place | A Quiet Place Part II
The mother of the family.
- Agony of the Feet: She steps on an exposed nail and can't stop a brief gasp of pain, further alerting the aliens to her presence.
- Demoted to Extra: Not quite "extra," but in the second half of the sequel, Evelyn is not quite as important to the story as Regan's journey to reach the radio tower. At the end of the movie, it is Marcus who kills the monster that is stalking the two of them while Evelyn watches with the baby. Somewhat justified here in that her leg had just been slashed by the monster moments earlier.
- Imperiled in Pregnancy: Because of the Agony of the Feet trope and that she had gone into labor
- Mama Bear: She will fight to her last breath to protect her children. Her one goal in life is to make certain they're safe (e.g., she would risk going into the water and the creature knowing where she is solely to rescue her baby. This also had practical reasons - as once she has the baby, the two are able to hide behind the gushing pipe and confuse the alien momentarily).
- Motherly Side Plait: Evelyn for most of the film has her hair in a low maintenance plait, which helps convey what a caring mother she is.
- Pregnant Badass: She is pregnant with their fourth child, and has to deal with the monsters in various ways. Her water breaks and she gives birth while the rest of the family is elsewhere, she has to not only fight through the contractions (mostly) without noise, she manages to give birth on her own.
Lee Abbott
Lee Abbott
Played By: John Krasinski
Appearances: A Quiet Place | A Quiet Place Part II note
The dad of the family, who tinkers with cochlear implants, looks after the family, and has been taking notes on the monsters.
- Beard of Sorrow: Grows one after the death of their youngest.
- Decoy Protagonist: The film's marketing strongly emphasized him as the hero of the film, especially given the fact that he is played by the director. Around three quarters in, however, he takes a mortal wound from a monster and sacrifices himself to draw it away from his teenage daughter Regan; it is she who is the true hero of the story, and is the one who figures out how to defeat the monsters.
- Determinator: For two things. One was his desperate attempts at understanding the monsters and their weaknesses. The other was fixing Regan's hearing aid.
- Dying Declaration of Love: Towards Regan before his Heroic Sacrifice.Lee: *signing* "I love you. I have always loved you."
- Heroic Sacrifice: Lee yells out to get the monster's attention, giving his kids the chance they need to escape, but dies in the process.
- Papa Wolf: He will defend his family, no matter what.
- Sacrificial Lion: His death serves as one.
Regan Abbott
Regan Abbott
Played By: Millicent Simmonds
Appearances: A Quiet Place | A Quiet Place Part II
The oldest and only daughter of the Abbots, who's deaf.
- Abandon the Disabled: Throughout the film, after Beau was killed by the monsters, she thinks Lee will do this. Marcus tries to tell her otherwise.
- Action Girl: Becomes this by the end of the movie, seeing as how she stabs an alien through the head with a pipe.
- Big Ol' Eyebrows: Her eyebrows are a prominent facial feature.
- Big Sister Instinct: She has this towards Marcus and Beau. The latter case plays this for tragedy, as she feels responsible for Beau's death
- Disability Superpower: Of the Mundane Made Awesome variety. Regan being deaf and her parents and siblings knowing sign language already gave them an effective way to communicate when sound-sensitive aliens attack. Her hearing aid likewise proves to be their weakness.
- Disabled Means Helpless:
- Played with. While she is deaf, she's no more vulnerable than the other characters when it comes to dealing with the monsters besides that she won't hear them coming (as demonstrated in one scene).
- There's also the fact that Lee doesn't take her along with him on errands, even when she volunteers and Marcus would rather stay home. While she clearly thinks it's because her father blames her, it can be deduced that he's merely worried about her making a noise, or being near a noisy animal, and not being able to realize it.
- Girlish Pigtails: She's had these in the opening of the movie.
- Handicapped Badass: Towards the end of the second movie, she's become an Action Girl slightly held back by her deafness.
- It's All My Fault: This is how she feels after Beau's death, as she gave him the space shuttle but didn't know he grabbed the batteries.
- Let's Get Dangerous!: She morphs into an action hero in film 2.
Marcus Abbott
Marcus Abbott
Played By: Noah Jupe
Appearances: A Quiet Place | A Quiet Place Part II
The middle and older son.
- Agony of the Feet: He steps right into a bear trap in the second film, which leaves him limping for the rest of the film.
- Character Development: He is the most skittish of the family, and at several points, his father has to physically cover his mouth to keep him from screaming. In the climax of the film, he has learned to be more resilient, and keeps his cool - which he then immediately forgets in Part II, though in fairness he was going through some rather extreme pain at the time.
- Delicate and Sickly: He has (or had) an unspecified illness that leaves him weak much of the time. The first scene involves the family traveling into town to get medication for him. In the second film, he steps in a bear trap early on, leaving him out of commission for much of the action and forcing Evelyn to again make a run for medical supplies.
- The Millstone: He causes a lot of trouble for his family. Especially in Part II where his inability to simply stay put and take care of his baby brother alerts an alien to the presence of the foundry hideout. It's finally subverted at the end, when upon hearing Regan's implant frequency on the radio broadcast, he's the one to use it to force the Death Angel attacking him, Evelyn and the baby back far enough to reach Evelyn's gun and blow its brains out, despite his injury. Evelyn's expression at his success shows both pride and relief that he's become capable enough to defend his family on his own if needed.
- Non-Action Guy: Even for a kid he's surprisingly cowardly and incompetent compared to the rest of the family. Making it more meaningful when he's the one to finally kill one of the death angels menacing him, Evelyn and the baby inside Emmet's shelter.
Beau Abbott
Beau Abbott
Played By: Cade Woodward (A Quiet Place) & Dean Woodward (Part II)
Appearances: A Quiet Place | A Quiet Place Part II note
The youngest kid of the Abbotts.
- Big Sister Worship: From what's implied, he's had this sort of relationship with Reagan and she's hit the hardest by his death.
- Children Are Innocent: Played for tragedy. His decision to switch on the toy rocket can only be excused by his age and lack of understanding towards the whole situation.
- Death of a Child: In the opening scene no less. The monsters don't discriminate.
- Gory Discretion Shot: We don't see him die, as he gets snatched by the monster and dragged offscreen.
- Kid Has a Point: In a sense, if we remember his comment about going to space in the beginning and considering what we see of the monsters. Of course, him being so young, he probably didn't understand that his family can't do that.
- Plot-Triggering Death: In a sense, as his death by the monsters plays a part in the rest of the drama, as, besides his family trying to survive, they're also coping with losing him, with Lee working on better protecting the family, Regan blaming herself for giving him his rocket, and Evelyn wishing she had carried him.
- Sacrificial Lamb: His death early on established the threat the monsters pose and that they mercilessly hunt based on loud noises.
- Too Dumb to Live: The primary issue the characters are facing in the movie is the constant presence of deadly monsters that attack anything that makes noise. Beau, despite warnings not to do this, wanders off from his family and switches on a noisy toy to play with. He dies shortly thereafter.
- We Hardly Knew Ye: We don't learn much about him except for his love of rockets.
Survivor Groups
The Old Couple
The Old Couple
The Old Man is Played By: Leon Russom
Appearances: A Quiet Place
A couple that Lee and Marcus come across on the way from their fishing trip.
- Despair Event Horizon: The old man was teetering on the verge of this when Lee and Marcus came across him from the brutal passing of his wife. Tragically, Lee's frantic gestures to remain silent, a reminder to him that he couldn't vocalise his sorrow even in his current predicament, served as the final straw, making him decide that a silent life like that wasn't worth living.
- Driven to Suicide: The Old Man after the death of his wife.
- Flies Equals Evil: We get flies and find them near the Old Woman's corpse.
- Gory Discretion Shot: Both of them, though we see the Old Woman's body but we don't too much.
- No Name Given: We don't get their names and they don't seem to be named in the credits.
- Taking You with Me: Played With. The old man technically wasn't trying to do this, as he just wanted to end his quiet, miserable existence, but he knowingly screamed out when Lee and Marcus were mere feet from him in open defiance of Lee's pleas to him to keep silent, clearly not caring if the aliens killed them too, and Lee and Marcus are afterwards left in danger from the alien once it's finished with him.
- The Voiceless: The old man doesn't speak. He only screams to draw the monsters over to him.
- We Hardly Knew Ye: We only see one dead and the other one get killed off.
Dock Bandits & Little Girl
Dock Bandits
Appearances: A Quiet Place Part II
A group of feral people that captures other survivors to rob or do even worse to.
- Asshole Victims: All end up very dead, with the leader receiving a particularly drawn out mauling.
- Death of a Child: Implied to be an offscreen case for the little girl who springs their trap on Emmett, given everybody else on the docks were massacred, but neither he nor Regan witness it.
- Decoy Damsel: The little girl at the marina is placed there to lure Emmett into a trap.
- Didn't Think This Through: Instead of holding others hostage with weapons like knives or even guns, their own noise maker collar doesn't make a whole lot of sense when you consider that their intent is to make noise to draw the creatures to them, which is the absolute last thing anyone should want and winds up being what kills them when Emmett uses their own device to summon two of the aliens to make short work of the bandits.
- Hoist By Their Own Petard: The collar of noise makers they wrap around Emmett's neck proves their own doom. He's able to use it to attract the monsters while he and Regan escape to safety. As a result the entire group dies except for their intended victims.
- Schmuck Bait: Little girl, middle of the night on a dock with aliens out there. Nothing could possibly be wrong with going up right to the girl who could scream at any moment.
- Too Dumb to Live: The bandits at the docks use noisemakers to prevent their victims from fighting back without endangering their own lives. It's surprising they've lived for so long without anyone pulling a Taking You with Me. Emmett quickly finds a way to not only use it against them, but also survive the aftermath.
- Unwitting Instigator of Doom: If they hadn't attacked Regan, Emmett would have stolen a boat and reached the island without incident. Instead, a monster ended up in another boat and killed a number of islanders.
- The Voiceless: Par for course in the setting, they have no lines.
- Would Hurt a Child: Attempt to drag Regan away to do God knows what to (implied to be rape when the leader removes her outer clothing).
Marina Man
Marina Man
Played By: Scoot McNairy
Appearances: A Quiet Place Part II
The leader of the Dock Bandits.
- Asshole Victim: He's viciously torn apart by an alien, but it's honestly hard to feel to bad for him.
- Beard of Evil: He sports a big, bushy beard.
- Cruel and Unusual Death: Unlike other victims of alien attacks, which are brutal but swift, his death lasts several long seconds. In that time, he's conscious and screaming in pain and terror as he's ripped apart by one of the aliens. What little is shown is not pretty, though it's hard to say he didn't deserve it.
- Gory Discretion Shot: Him being torn apart by an alien is kept out of frame for the most part, except for a few brief shots.
- Jerkass: While he doesn't speak, he clearly gets a lot of pleasure in tormenting Regan and Emmett.
- Karmic Death: His attempt to rob Regan and Emmett and presumably kill them results in him and the rest of the bandits being killed by the aliens. Emmett ties him to a post in the path of one of the rampaging creatures, stabs him in the leg with his own knife to make him scream, and leaves him to be brutally mauled by one of the aliens. It's notably horrific because while most of the aliens kill their prey in one hit, this person is alive long enough to scream for several seconds as he's being ripped apart.
- Oh, Crap!: He visibly panics right before an alien starts tearing him apart.
- Rape Is a Special Kind of Evil: The ringleader seems to have an unsavory interest in Regan, as evidenced by his attention towards her body after removing her outer clothing.
- The Voiceless: Understandably, given the setting, he never speaks.
The Islanders
The Islanders
Appearances: A Quiet Place Part II
A large group of survivors who escaped to an offshore island during the initial disaster.
- Chekhov's Gun: They have control of a radio station. Regan has a short range audio weapon that can harm the aliens. Combining the two becomes the main goal of the film.
- Conditioned to Accept Horror: On the island, when an alien finds its way there, Emmett and Djimon Housou's character grab a couple of children and hide them in a closet. Both children respond with almost unnerving calm, as though this was a practiced scenario.
- Cosy Catastrophe: They're largely living thorough one. Like the Abbott's in the first film they have a secure location, food, comfort and they are in a location where they can easily speak. Unfortunately events see one alien enter their community.
- Hope Bringer: They try to be this using their broadcast to let people know others are still out there. For the Abbott's hearing that broadcast is the first good thing in a horrible day.
The Man on the Island
The Man on the Island
Played By: Djimon Hounsou
Appearances: A Quiet Place Part II | A Quiet Place: Day One
The leader of the Islanders.
- Foregone Conclusion: Is set to be a character in A Quiet Place: Day One, so anyone whose seen A Quiet Place Part II knows he'll survive to become the island colony leader.
- Hero of Another Story: He's implied to have had his own experiences with the aliens before making it to the island, but we only get to hear about some of it from his monologue. Ultimately subverted as the announcement and promotional material of A Quiet Place: Day One shows that his backstory will be explored somewhat.
- Nice Guy: He's shown to be a pleasant, affable, and mellow guy who's nothing but accommodating and welcoming to Regan and Emmett.
- No Name Given: His name is never mentioned onscreen.
- Surprisingly Sudden Death: While arguing with Regan and Emmett after they lure the alien to the radio station, it suddenly reaches through the garage door and drags him off.
- Wasteland Elder: The man is in his late fifties and leads a small community of people on an island that the evil alien monsters can't swim to.
Other Humans
Emmett
Emmett
Played By: Cillian Murphy
Appearances: A Quiet Place Part II
A family friend of the Abbotts. He managed to survive the alien invasion and has been hiding out in an abandoned steel mill.
- Action Survivor: He's survived both the aliens and not particularly friendly humans through traps and hiding.
- Anti-Hero Substitute: While similarly brave and capable as Lee, the losses in his life have made him much more pessimistic and distant.
- Badass in Distress: When Regan has to pull him out of the water.
- Cold Sniper: He's introduced in the present day watching the Abbotts through a sniper rifle.
- Contrasting Sequel Protagonist: Whereas Lee was a Papa Wolf who did everything to protect his family, Emmet's a cynical loner who had no interest in shearing his survival space with anyone. As Regan repeatedly states upon meeting him he's nothing like her dad, this soon changes.
- Dark and Troubled Past: He lost his family during the apocalypse, and it's implied he's run into hostile humans, which has scarred him so deeply he's set up the foundry he's hiding out in with traps to lure aliens to kill anyone who enters.
- Humans Are Bastards: Holds this view about the surviving members of humanity.
- Jerk with a Heart of Gold: He starts off as a selfish survivalist, but develops into this as he travels with Regan.
- Knight in Sour Armor: He's rather cynical, but ultimately chooses to help Regan.
- The One Who Wears Shoes: Is this compared to the Abbott family, who are barefoot for the entirety of both films.
- Refusal of the Call: He initially rejects joining Regan on her journey but gives in after a night of reconsideration.
- Replacement Goldfish: Having lost his own family, he slowly begins to view the Abbotts as a substitute found family, growing especially protective of Regan.
- Sole Survivor: The only surviving member of his family.
- Suspiciously Similar Substitute: While starting out as a Contrasting Sequel Protagonist to Lee, Emmet slowly turns into a substitute for Lee, another bearded Crazy Survivalist with Papa Wolf behaviors.
Officer Ronnie
Officer Ronnie
Played By: Okieriete Onaodowan
Appearances: A Quiet Place Part II
A cop who served in the Abbott's town. He was slain by an alien during Day 1.
- Black Dude Dies First: The only speaking character killed by the aliens in the opening sequence of Part II.
- Dying Moment of Awesome: He goes out shooting at one of the aliens without even flinching immediately after shrugging off being attacked by one.
- Gory Discretion Shot: Him being killed by an alien is obscured behind his overturned police car.
- Heroic Sacrifice: He takes on an alien so the Abbotts can escape.
- Made of Iron: He gets up from being thrashed around by one of the aliens without a scratch, though he is knocked out for a minute.
- Screaming Warrior: He yells as he desperately he tries to take down one of the aliens with his sidearm. Unfortunately, this only enrages the creature and hastens his death.
- We Hardly Knew Ye: He's only around for the opening scene of the second movie before dying.
The Monsters
Death Angels
Death Angels
Appearances: A Quiet Place | A Quiet Place Part II
Hostile extraterrestrial predators that arrived on earth via asteroid after their homeworld was destroyed. They hunt exclusively by sound and kill anything that produces noise.
- Absurdly Sharp Claws: Their claws can rip through metal like paper, unless the Rule of Drama demands otherwise.
- Achilles' Heel: The creatures are quite vulnerable to high-pitched frequencies that appear to place them in so much agony they become paralyzed with their armor stripped from their heads. The sequel shows that if sufficiently determined they can press through this, but are in immense pain, and it's implied the one we see doing so was only able to head towards Regan because of the cramped linear conditions they were in. Also, we learn in the sequel they can't swim. A Downplayed example is also shown, in that Regan managing to land a grazing shot to one of the creature's heads blows away part of its armour plating and head, and its right arm apparently not moving properly afterwards from the damage, suggesting that any attack to the head will sufficiently impair one if it doesn't get outright killed from it.
- Ax-Crazy: Paying attention to The Big Board in Lee's workshop reveals that the beasts don't eat their kills, making their rampages much more senseless. It's much more ambiguous than most examples, as we don't know why they do it. One of them even pushes through a concentrated exposure from Regan's implant to try and kill her, showing that they're driven to kill humans regardless of how much they're hurt doing so, but without any discernible reasoning why.
- Bat Out of Hell: Although they lack wings, the monsters' body shape is noticeably similar to the way a bat looks when it's on all fours. The impression is reinforced by their powerful ears and reliance on sound, though thankfully for the human survivors, they don't echolocate like bats do.
- Berserk Button: Obviously, making particularly audible noises is this for the alien beasts, but it goes further when Regan accidentally discovers that they can be harmed by certain pitches and frequencies, and as a result, one of the beasts tears through the silo's metal wall like it was tissue paper. When she uses the frequency to force an alien to expose its weak spot and partially grazes it with a shotgun blast, the creature is apparently so enraged by actually getting hurt by her that it pushes through the sounds waves to get closer to her, despite being in immense pain and with damaged motor functions.
- Big Bad: Their arrival on Earth is why society collapsed and the survivors are now in hiding.
- Bizarre Alien Biology: They are humanoid creatures covered in armor. They have no eyes, but the armored plates on their heads can be moved by muscles to expose the soft skin beneath, including giant ear canals that they use to hunt with.
- Creepily Long Arms: They have spider-like limbs.
- Crippling Overspecialization:
- The monsters hunt exclusively by sound, not sight or even echolocation, and as such are easily fooled and even distracted by bigger sounds. A specific high-pitched frequency from Regan's cochlear implant is outright painful for them, causing spasms that leave their soft hearing organs and brains unprotected.
- The monsters have long arms and legs with sharp claws that make them adept at hunting their prey over any terrain, but their heavy armor and lanky build make them utterly incapable of swimming or floating.
- Eyeless Face: There was no light on their homeworld, so these creatures evolved without eyes, but gained hyper-sensitive hearing to compensate.
- Fire/Water Juxtaposition: The sequel reveals that they are completely immune to fire or high temperatures, which is part of the reason they were able to enter Earth's atmosphere in the first place. Evelyn blowing up an oxygen canister underneath one barely fazes it apart from the noise of the explosion. Conversely, water often turns out to be the best defence against the creatures' sharp hearing, with loud natural or artificial running water sources allowing characters to move around or have low conversations with each other masked by the constant noise produced. Additionally, it's revealed that the armour that makes them so fire-resistant also means they sink like a stone in deep enough bodies of water, their long, narrow limbs are useless for swimming, and their hearing cannot penetrate the surface of water, meaning that diving into a lake or other large water source prevents them from following.
- Flower Mouth: Their cranial plates are divided into petal-like segments that fold away from each other when opened, causing their face to expand like an armored flower when they're hunting.
- Generic Doomsday Villain: The film primarily focuses on the threat they pose to the family. Their motivations are never explained, but the fact they don't eat their kills makes it clear they aren't hunting for survival. Their seemingly senseless violence makes them all the more alien and frightening.
- Immune to Bullets: Unless their delicate hearing organs on their heads are exposed, they are unaffected by small-arms fire. Even a shotgun blast does little to them.
- Immune to Fire: The aliens can survive being set on fire, and it's implied that this is in part how they survived entering Earth's atmosphere.
- Insectoid Aliens: The creatures' legs suggest this.
- Invincible Boogeymen: These creatures are always lurking just out of sight, show up within seconds when someone makes a noise, and are practically impossible to kill without being incapacitated by high-frequency sound first.
- Kill It with Fire: Evelyn attempts this on one of them in the sequel, but it doesn't work. The flames prove to be little more than a mild inconvenience to the creature.
- Lightning Bruiser: They are strong enough to rip through a metal grain silo effortlessly, have extremely durable armour, and to top it all off, are so fast they can arrive on the scene in moments when something gets their attention.
- Logical Weakness:
- A monster with such powerful hearing is naturally weak to loud and high-frequency noises. And, in spite of the armored body, it will experience enough pain from the loud noise to expose most of the head, making it a notable weak point that can be damaged by various methods, such as a shotgun blast.
- They're heavily armored with a body clearly meant for climbing and leaping, leaving them incapable of swimming.
- More Teeth than the Osmond Family: Their heads are mostly sharp teeth and a series of armored plates hiding massive ear canals.
- Names to Run Away from Really Fast: Although none of the characters refer to them by that name, newspaper clippings on the wall reveal that the creatures are commonly known as "Death Angels" or "Dark Angels," presumably because they Came from the Sky.
- The Needless: Possibly tied with being Perpetual Motion Monsters. They apparently don't eat what they kill, and considering their origins, they don't need to breathe either.
- The Misophonic: Zigzagged. They use sounds primarily to hunt their prey but they hate extremely loud and ear-piercing sounds.
- Nigh-Invulnerability: What really makes the aliens the threat they are, more so than any other quality, is their armor plating. When fully locked down, they are completely indestructible. It's what allowed them to survive the destruction of their world, entry into the earth's atmosphere, and collision with the earth's surface. They're that tough.
- Non-Malicious Monster:
Word of God is that the aliens aren't sapient and are more like vicious animals. Their behavior in the film lends credence to this as they appear to run entirely on aggressive instinct rather than sadism. That said, some of them do show that they can get sufficiently angered and motivated to attack if hurt in any capacity. - Nothing Is Scarier: Despite being vicious predatory aliens, they don't actually eat anything that they kill, making their ruthless behaviour appear quite senseless and horrifying. The fact that we never find out why they attack anything that makes a sound makes them all the more scarier.
- Sense-Impaired Monster: They're entirely blind and track their prey by sound, and as such cannot perceive silent entities outside of stumbling directly into them. As they're far too dangerous to fight directly, the humans who survived their initial onslaught are placed under a total ban on noise; this results in a number of notable scenes, such as a character needing to remain quiet after stepping on an exposed nail or a woman having to be silent through childbirth while a monster pokes its head into the room, listening for prey.
- Sensory Overload: They can't stand high-frequency/pitched sounds.
- Super Drowning Skills: The aliens are unable to swim, allowing a group of survivors to set up a civilized refuge on an island.
- Super-Persistent Predator: The monsters are utterly relentless and when they hear a noise, they will not stop until they've killed something.
- Super-Senses: The monsters have very sensitive hearing.
- Walking Techbane: They cause electronics to go on the fritz just by being near them. A recurring signal that they are around is the lights beginning to flicker. This combined with the daughter's cochlear implant causes a sound feedback that is physically painful to the monsters.
- Weaksauce Weakness: The sequel reveals that, for all their indestructible armor plating, the monsters don't know how to swim.
- Xenomorph Xerox: The Alien influence is pretty obvious in the thin body, elongated limbs, and eyeless head with a mouthful of sharp teeth. Not to mention the Implacable Man behavior. Their design also calls to mind the Demogorgon and the Future Predators.
