''This page is for the films. The games and comics can be found [[Franchise/AlienVsPredator here]].''

What would happen if the Franchise/{{Predator}}, interstellar alien hunter extraordinaire, took it upon himself to go after the [[FaceFullOfAlienWingWong face-raping]] [[Franchise/{{Alien}} Aliens?]] Oddly enough, [[TakeAThirdOption lots of humans dying]].

''Alien Vs. Predator'' is the [[CrossOver combination of Fox's two hit alien monster movies]], and the stories of the innocent humans caught in the middle. The concept was even hinted at in the second Predator movie, which featured a Xenomorph skull amongst the Predator's trophies. It was made into a movie in 2004, and a sequel, ''Requiem'', was made in 2007. The movies abandoned the previous setting and had the conflict take place on contemporary Earth. That the movies weren't exactly embraced (though the first film was ''slightly'' better received by audiences), even by the fanbase, owes to the fact that the movies Human protagonists were the weakest element and simply weren't credible enough, with even the Aliens and Predators not being on form; the Predators of the first film came off as absurdly incompetent and TooDumbToLive, with their appearance being too bulky and clumsy looking, while the second film had the Aliens who were equally incompetent (if not more so), with their design also being disapproved of by the fans. This is coupled with a unbelievably sped up life-cycle and absolutely hated new one thanks to Chet the Predalien.

The games, along with a series of comics and novels, are completely unrelated to the story or setting of the movies. They are instead set in the same timeline and setting as ''Film/{{Aliens}}''.

!!Tropes in both films (specific films each follow this section):

* CorruptCorporateExecutive: Anyone high up in WY ([[CoolOldGuy except the very first original Mr. Weyland]]) is guaranteed to be doing something dangerous, unethical and in all likelihood ''stupid'' involving the nearest Hive and / or ancient ruins. It's apparently true for the whole corporation: Weyland-Yutani's contract has a clause that allows them to feed you to a Xenomorph [[ForScience just to see what happens when they feed you to a Xenomorph.]]
* {{Crossover}}: Self-explanatory.
* DevelopingDoomedCharacters: Both are widely considered badly done examples.
* DVDCommentary: Both AVP movies have them.
* EvenEvilHasStandards: Predators do not kill certain targets such as children and pregnant women. In the first movie there's even a scene where a predator refrains from killing a man because it sees that he is dying of terminal cancer. [[spoiler:Of course, he changes his mind when the human attacks him with a makeshift flamethrower, but even then, he makes the kill quick and clean.]]
* FaceFullOfAlienWingWong: Being a film that includes Aliens, people getting facehugged is inevitable, unlike the four alien films, in which one person is visibly facehugged, the AVP films have the highest count of it with five people facehugged in the first film and four in the second.
* FinalGirl: Everyone but Alexa Woods are killed, leaving her alone with the last remaining aliens and the last predator; ultimately she is left to fight the Queen alongside the last predator who is slowly dying from his wounds.
* {{Homage}}: Both films were criticized for being too derivative -- homage taken too far.
* ImmediateSequel: The two films could be spliced together into one pretty easily.
* KillEmAll: The first movie has only ''one'' survivor, [[WhatHappenedToTheMouse who was left in the middle of Antarctica]]. The second movie has only four survivors, which is actually worse given that the movie takes place in a large town and not in the middle of a frozen wasteland.
* RecycledInSpace: In an inversion, the ''Alien Vs. Predator'' movies sees the Aliens on Earth as opposed to [-IN SPACE!-]
* TooDumbToLive: Pretty much everybody but a few stand out, Adele in the first film failed to kill the emerging facehuggers when first seen despite Thomas telling her about what room they were in, her hesitation results in her getting facehugged. Miller after being cocooned manages to get a gun but wastes many bullets on a dead facehugger. Sam and Buddy from the sequel, Buddy shoots an alien point blank and gets acid on his arm and rather than quickly take off his jacket off he just stands there letting the acid burn his arm off. His son is not much brighter as he also just stands there watching his father on the ground and his inaction costs him.
** The statement "I've never seen a gun help anyone out on the ice" would probably be an indicator of someone being too dumb to live if the movie wasn't conspiring to prove the utterer of it right (because no ''human'' gun winds up being of any use, and the Predators focus mostly on melee weapons in this film).
* VasquezAlwaysDies: Despite the source movie being the TropeNamer, it's somewhat averted in both films. In [=AvP=] the lead is equally as badass as the "Vasquez" clone (who dies first), and in ''Requiem'' she's the lead herself.
* VersusTitle

[[caption-width-right:203:"Whoever Wins, We Lose"]]
!!Tropes in the original ''AVP: Alien vs. Predator'':

* AbusivePrecursors: The ancient humans were basically used as incubation units for the xenomorphs, just so they could practice combat skills.
* AerosolFlamethrower: Charles Bishop Weyland does this as a HeroicSacrifice with a flare and a medicine inhaler. He gets butchered by a Predator hunter because he had a weapon, trumping the fact that he's a sick old man who the hunter would ignore otherwise.
* AncientAstronauts
-->[the team finds the Predators' shoulder cannons]
-->'''Miller:''' Any idea what these are?
-->'''Rosa:''' No, you?
-->'''Miller:''' No.
-->'''Stafford:''' It's a good thing we brought the experts.
-->'''Miller:''' Well, yeah, it is a good thing, cos' this is like finding Moses' DVD collection.
* ArtisticLicenseHistory: Why the Pyramid in the first movie operates on 100 year cycles according to their ''archaeologist''. None of the cultures that are supposedly the influenced by the builders, used anything close to that in their counting systems at the time-period given. In fact, given the high Mayan influence, it'd been more accurate to say the Whaling station was lost in 1900 instead of 1904, due to the fact that the Mayans ''did'' use 52 lunar cycles and that 2004 is exactly 2 cycles afterwards, meaning that a dead 1952 crew by the pyramid would have made sense. Not to mention that the ''Hunters Moon'' joke would have been even more as as ironic.
** Once activated, the pyramid shifts every 10 minutes. The problem is, Mayans did not have a unit of time which corresponds to a minute. In case you are curious, it originates from Babylonia.
* AvengersAssemble: The 2004 film starts off like this.
* {{Badass}}: The "Grid" Alien from the first movie: he [[ImpaledWithExtremePrejudice stealth kills]] a predator as an entry and faces another in one of the franchise's most badass fight scenes. and wins!
** Scar and Lex count as well
* BadassGrandpa: Charles Weyland stands up to a Predator and, when it tries to leave him after detecting his illness, ''provokes'' it into killing him to give the others time to escape.
* BlackDudeDiesFirst: Averted in the first movie where Lex, one of the few examples of a black female lead in a Sci-fi horror movie, was the only person to survive.
* DefiantToTheEnd: "Don't you turn your back on ''me''!"
* DontYouDarePityMe: Charles Bishop Weyland, a wealthy elderly industrialist, who funds the mission to a newly-discovered pyramid under tons of ice. He later reveals to the protagonist that he's dying of lung cancer and wants leave his mark on the world. Later, as the survivors are running from a Predator, Weyland tries to have a YouShallNotPass moment. The Predator scans him, sees his deformed lungs, and just walks right past the old man. The pissed off Weyland attacks the Predator with a makeshift flamethrower. ''Now'', the Predator won't ignore him and goes all stabbity on the guy.
* TheDragon: The "Grid" alien to the Alien Queen. He's by far the most dangerous of the Xenomorphs. Where the rest are killed off by the dozens by a single Predator, Grid kills ''two'' of them by himself and manages to evade Scar's Plasma Caster shots when they're aimed right at him while the rest of the drones simply get mowed down. He's also the one who leads his siblings in freeing the Queen. The novelization even refers to him as "the Alpha-alien", implying he's higher ranked than the other drones.
* EnemyRisingBehind: The Xenomorph who tries to attack the sole Predator left in the pyramid.
* EverybodyWasKungFuFighting: Did that Predator just uppercut that alien?
* FatalFamilyPhoto: During an early scene in the first film, Graeme shows Alexa a picture of his kids. Things do not work out for him. In a variation of this trope, RedShirt Verheiden mentions to Graeme that he has a son...about five minutes before he's snagged by an Alien.
* HeroicSacrifice: Weyland.
* InfraredXRayCamera: This is how they find the pyramid in the first film. Also, the Predators can see their plasma casters through people's bags in infrared.
* IronicEcho: Lex gives one to an alien from the entire Predator franchise [[PreMortemOneLiner before]] she [[BoomHeadshot blows a hole in the aliens' head]] ""You're one ugly motherfucker""
* LesserOfTwoEvils: The surviving humans ultimately decide that giving Scar back the plasma caster they'd taken so he can more effectively combat the aliens is their best chance to survive.
* MisplacedWildlife: The first movie, set in [[MysteriousAntarctica Antarctica]], has a CatScare with a penguin. The problem is, the penguin is an ''[[http://en.wikipedia.org/wiki/African_Penguin African]]'' Penguin, which don't live in Antarctica.
* MysteriousAntarctica: The first movie is set there.
* OhCrap: Scar the Predator does this when he sees the Alien queen emerge from the ice.
* OutrunTheFireball: Scar and Lex do this from his (detached) wrist-device nuke. Their survival was aided by a mile of ice containing the blast, and the shockwave caught up to them regardless.
* [[CatScare Penguin Scare]]
* RedShirt: A literal example as after being facehugged, Adele is killed by a chestburster emerging from her chest and ripping through her red shirt.
* ShoutOut: The sub-plot of a human female displaying enough courage and prowess (namely by killing a couple of Xenos) for a Predator to fight alongside her and blood her as a warrior, with her then killing a Queen alien before the predator dies from his wounds, is all taken from the ''Alien vs Predator: Prey'' novel, in which exactly this happens between Machiko Noguchi and "Broken Tusk". Unlike Alexa, however, Machiko would go on to live with the Predators and eventually become fully accepted into their ranks (albeit while still facing some bigotry).
* SoleSurvivor: [[spoiler:Alexa. The rest of her team mates are all killed.]]
* SpaceIsNoisy: Averted surprisingly in the first movie, its completely silent in space apart from the soundtrack. The only noise heard comes from the inside of the Predator ship, where the camera is.
* StatOVision: A predator decides not to kill [[spoiler:[[NotWorthKilling Weyland because it can sense that he's already dying of cancer.]] [[HeroicSacrifice Then Weyland improvises a flamethrower to buy the others more time...]]]]
* TooDumbToLive: One of the Predators have caught Grid in a constricting net and his blood is clearly melting it. The Predator, instead and rushing in and finishing him off, takes a ''slow'' walk towards him, which result Grid jumping him and impaling him when he gets too close
* TookALevelInBadass: Lex.
* ZombieInfectee: [[spoiler:Scar is impregnated by a facehugger after his marking ritual, but the next time we seen him, he is shown putting on his mask as if nothing, and he spends the rest of the film acting as if he didn't know about the Alien inside of him.]]

[[caption-width-right:214:"This Christmas There Will Be No Peace On Earth."]]
!!Tropes in ''Aliens vs. Predator: Requiem'':

* AnachronismStew[=/=]ArtisticLicenseMilitary: The AVP wiki stated that AVP-R took place a few days after the original; the U.S. National Guard troops wear ACU uniforms, which weren't issued until 2006.
* ArtisticLicenseGeography: This film is set in Gunnison, Colorado. However, the terrain in the movie is a lot less mountainous than in the real Gunnison, Colorado. Additionally, when the National Guard is summoned from Colorado Springs they arrive almost instantly. In real life, Colorado Springs is 3 hours away from Gunnison.
* AssholeVictim: The JerkJock ends up getting his face melted by the Xenomorph acid, and his friends get mutilated by one.
* AbandonedHospital: The climax of ''Requiem''.
* AbsurdlySpaciousSewer: ''Requiem'' So big the Aliens were setting up a hive down there before the Predator showed up and drove them out.
* BadAss:
** Wolf Predator from the second movie: [[BadassGrandpa Highly experienced]], with a lot of so badass weapons to hunt, and yeah, he [[CurbStompBattle curb stomped]] a lot of xenos without taking a sweat, and makes a very badass fight with the Predalien where all other predators were cannon fodder!
** The Predalien too: [[AsskickingEqualsAuthority pack leader]], [[CurbStompBattle Curb stomps]] an entire predator ship's crew and is so badass to fight an ancient, high-experienced predator as Wolf and get a final tie!
* BattleInTheRain: The climax of the movie.
* BigBad: The Predalien takes center stage throughout the movie as the biggest and scariest alien around. It immediately destroys the Predator ship, creates a Xenomorph army to invade the rest of Earth, harvests a whole town, and causes the Wolf Predator to come down to kill it in response.
* BlindObedience: ''"The government wouldn't lie to us!"''
* BloodierAndGorier: The first film isn't exactly blood-free, but ''Requiem'' really cranks up the {{Gorn}}.
* BullyingTheDragon: Whenever the human characters fuck with the Predator instead of just leaving it the hell alone, it's definitely this. The main character seems to catch the hint during the finale; he chooses to simply leave the Predator alone and sure enough the Predator ignores him.
* BurgerFool: The lead in ''Requiem'' works as a pizza delivery boy. All the other characters go out of their way to tell him how humiliating this is.
* CallBack: [[Film/{{Predator}} "Get to the chopper!"]]
* CanonImmigrant: The [=PredAlien=] goes from a enemy in the PC game to an official sub-species in the second movie. There's also the different vision modes the Predator uses to spot aliens instead of humans in the first movie.
** That in turn was an explanation of the vision modes used in ''Predator 2'', where it found the heat-cloaked humans by switching settings.
* DarkerAndEdgier: As noted under BloodierAndGorier, the body count and visible violence is very much cranked up. But the film also abandons one of the usual concepts of most ''Aliens versus Predator'' ventures (including the first movie): humans and Predators forced to team up to take out a bigger threat. Wolf is instead [[WordOfGod meant to be]] like a "force of nature" that's as much or more of a risk to the human characters as the Xenomorphs, and is an antagonist all the way through; he never even shows the grudging respect for human characters that has also been a trait of ''Predator'' films and the ''[=AvP=]'' properties. It's also implied that even the few survivors at the end might be "silenced" by the government. Overall the tone is a lot more bleak than the other entries in the ''Predator'' franchise.
* DeathBySex: Probably the reason the girl in ''Requiem'' dies. She strips down to almost nothing in the pool scene.
* DramaticThunder: The climactic battle in the hospital.
* DoubleTap: [[ExaggeratedTrope Exaggerated]]. The alien who kills the above mentioned JerkJock's friends stabs the dead body of the friend in the head over and over again, way more than needed. Could be considered TemptingFate''/''KarmicDeath since Wolf impales him exactly the same way while he is doing it
* DownerEnding: In a WhatCouldHaveBeen example, during the [[WordOfGod Brothers Strause]] DVDCommentary they mention that they had an idea of the ending where after handing off the Predator weapon to the military, the "rescuers" lifted up their weapons and the screen would cut to black with the sound of the rifles firing full-auto. Ouch.
* FateWorseThanDeath: It's implied that the mother impregnated (in the hospital) by the predalien can ''feel the multiple bursters breaking into her womb and eating her children''.
* GenreBlind: "The government wouldn't lie to us!". Anyone who has seen any ''Alien'' or ''Predator'' thing ever can tell you how wrong that is.
* GoryDiscretionShot: Averted. All the {{gorn}} is put on full display, such as when we see an Alien impregnate a pregnant woman and the "babies" eat their way out later.
* HybridMonster: The Predalien, though it's not truly a hybrid since aliens always take traits from their host.
* ImperiledInPregnancy: The Predalien is completely indiscriminate in its victims, invading a maternity ward in the town's hospital and implanting pregnant women with its own xenomorph embryos.
* InfantImmortality: Gleefully averted in the second film, which has the aliens killing kids and [[BlackComedy even eating babies]]. However, [[GoryDiscretionShot none of it actually happens onscreen]], except for one kid falling victim to a facehugger.
** One of the final four survivors is a child though
* InstantSedation: Facehuggers seem to be able to knock someone out within six or seven seconds in this film, people have thought that they use their tails to knock someone out but that would require a precise chokehold (a blood choke specifically) but the speed of the knock out suggests they sedate their host though some unknown means, the best examples are the two homeless men as one is unconscious within seven seconds and the other even less.
* JustFollowingOrders: This is how the soldiers react when called out on [[spoiler:destroying the town with a nuclear bomb]].
* MarketBasedTitle: ''Requiem'' is known in some countries as ''Aliens VS Predator 2'', conveniently [[FridgeBrilliance combining the names of the second Alien movie and second Predator movie into the second AvP movie.]]
* TheMountainsOfIllinois: In ''Requiem'', the shot of "Gunnison" clearly is not. The mountains are far too small and the town is far too big.
* NeckLift: Wolf does this simultaneously to two aliens who attempt ambush him
* NoOSHACompliance: The power goes out in ''AVP Requiem'', and it seems that not a single building in the town has emergency lighting, and the hospital's emergency generator mostly just makes the fluorescent lights flicker.
* RedshirtArmy: The National Guard unit sent to Gunnison only gets about ''a minute'' of screentime before they're all killed in an alien ambush.
* SlasherMovie: Some fans complained that AVP-R turned both franchises into mere Teen Slasher monsters, screaming blond and all.
* TelevisionGeography: Virtually every shot of "Gunnison, Colorado" is wrong. Basically the city is too big and the mountains are too small.
* TooDumbToLive: Several:
** The Predators in the ship who carry Scar's body do not scan him for any Xenomorph infestation. Even if that is counted out due to being overlooked since Scar's dead, it does not explain the stupidity of one Predator who opens fire on the Predalien which causes the ship to crash.
** The father and son who should've taken off immediately, stop some time when the boy falls down,and are taken out by the facehuggers. Especiallyy the boy who never moves
** The homeless men who were staring into the bubbling water, doubly glaring since their dog found pieces of a corpse in the sewers. Even removing the fantasy parts of the movie, there are many lethal creatures who could be in the water, like snakes. They were asking to be dead.
** One alien who attacks and disables one of Wolf's plasma cannons, hisses at him and ''slowly'' moves towards him. The results are predictable
* WalkingArmory: Wolf, especially after taking up the fallen Predators' weapons.
* WhipSword: Wolf's bladed whip can slice up an enemy by wrapping around him and pulling in.
