->'''Alexa''' "'''Lex'''" '''Woods:''' We're in the middle of a war. It's time to pick a side.\\
'''Sebastian de Rosa:''' We are on ''[[TakeAThirdOption our]]'' side!

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 2004 [[CrossOver combination of Fox's two hit alien monster movies]], and the stories of the innocent humans caught in the middle. It was directed by Creator/PaulWSAnderson and is the first film in either franchise to be rated PG-13.

When a mysterious heat signature is detected in Antarctica, billionaire Charles Bishop Weyland (Creator/LanceHenriksen) assembles a crack team of explorers led by Lex Woods (Creator/SanaaLathan) to investigate. They discover an underground pyramid containing human remains, but the team accidentally trap themselves when they activate the structure. The team soon find themselves caught in the middle of a centurial RiteOfPassage held for young Predators, who hunt the Xenomorphs who lie dormant within the pyramid. With their number dwindling, the team must find a way out before they are hunted down by either side.

The concept was first hinted at in the second ''Predator'' movie, which featured a Xenomorph skull amongst the Predator's trophies. The film was followed by ''Film/AliensVsPredatorRequiem'' in 2007. The movies abandoned the futuristic setting of the comics and had the conflict take place on contemporary Earth. The movies weren't exactly embraced (though the first film was ''slightly'' better received by audiences), even by the fanbase. Most people point to ExecutiveMeddling as the cause of the films' failures.

The games, along with a series of comics and novels, are completely unrelated to the story or setting of the movies, and have been rendered non-canon - at least to the ''Alien'' universe - with the release of ''Film/{{Prometheus}}''. To see the tropes for the games and comics, see [[Franchise/AlienVsPredator here]].

!!Tropes in ''AVP: Alien vs. Predator'':
* AbusivePrecursors: The ancient humans were basically used as incubation units for the xenomorphs, so the Predators could hunt the ultimate prey.
* AerosolFlamethrower: Charles Bishop Weyland does this as a HeroicSacrifice with a flare and a medicine inhaler. He gets butchered by a Predator hunter [[WorthyOpponent because he had a weapon, trumping the fact that he's a sick old man the hunter had been willing to let live.]]
* 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; the Mayans ''did'' use 52 lunar cycles, and 2004 is exactly 2 cycles afterwards. A dead 1952 crew by the pyramid would have made sense. Not to mention that the ''Hunter's Moon'' joke would have been even more 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.
* 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.
* {{BFS}}: The Predators' iconic wrist-blades are much larger in this movie than in previous iterations. ItMakesSenseInContext as the Predators in prior films were hunting humans, whereas Xenomorphs are a far tougher game, and using larger weapons makes just as much sense as a human hunter using a larger caliber rifle to kill a lion than a deer.
* CanonDiscontinuity: ''Film/{{Prometheus}}'' presents a completely different origin for the Weyland-Yutani corporation, making the ''Alien vs. Predator'' series non-canon.
* CleanCut: A Xenomorph falls victim to this.
* 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.
* DefiantToTheEnd: "Don't you turn your back on ''me''!"
* DevelopingDoomedCharacters: Widely considered a badly done example.
* 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 takes him out.
** A popular fan theory is that the predator knew that Weyland presented no actual threat to him, but he so respected Weyland's courage that he granted him a warrior's death.
* TheDragon: The "Grid" alien to the Alien Queen. She'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 herself. She even manages to evade Scar's Plasma Caster shots when they're aimed right at her, when the rest of the drones were simply mowed down. She's also the one who leads her siblings in freeing the Queen. The novelization even refers to her as "the Alpha-alien", implying she's higher ranked than the other drones
* EnemyCivilWar: What the humans find themselves in, although they end up allying with the Predators.
* EnemyMine: Lex and Scar forge an uneasy alliance in the second half of the film.
* EnemyRisingBehind: The Xenomorph who tries to attack the sole Predator left in the pyramid.
* EvenEvilHasStandards: Predators do not kill certain targets such as children and pregnant women. 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 and didn't take a trophy.]]
* EverybodyWasKungFuFighting: Did that Predator just uppercut that alien?
* 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 this movie.
* 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.
* FinalGirl: Everyone but Alexa Woods is killed, leaving her alone with the last remaining aliens and the last predator; ultimately she is left to fight the Queen alongside Scar.
* HeroicSacrifice: Weyland.
* {{Homage}}: The film was criticized for being too derivative -- homage taken too far.
* InfraredXRayCamera: This is how WY finds 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""
* KillEmAll:
** The movie has only ''one'' survivor, [[WhatHappenedToTheMouse who was left in the middle of Antarctica]]. The novelization clears up Lex's fate -- the ship everyone arrived on had a separate crew which stayed behind while everyone went exploring. Presumably Lex was able to contact them once she got back to base camp.
* 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.
* LockAndLoadMontage: The Predators get one, checking their weaponry and blades just before they beam down.
* 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.
* NoSell: In at least one instance a human punches an oncoming Predator, the latter seems at best, mildly annoyed.
* OhCrap:
** Even the Predators with all their technology start getting jumpy when the Aliens are creeping about, just to show that they do know how frikkin' dangerous those things are (unlike the moronic corporations of the future who believe they can handle it.)
** Scar the Predator does this when he sees the Alien queen emerge from the ice.
** The team in the "Sacrificial Chamber" have one when the facehugger eggs rise from the floor, and they realize something very bad is about to happen.
* 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]]
* RecycledInSpace: In an inversion, the movie sees the Aliens on Earth as opposed to [-IN SPACE!-]
* RedShirt: A literal example as after being facehugged, Adele is killed by a chestburster emerging from her chest and ripping through her red shirt. Nearly all of the other humans qualify, as many are well-armed yet most die without getting off a shot, and those that do are not saved by it.
* SequelHook: [[spoiler:At the end of the movie, a Chestburster emerged from Scar's body, setting up the stage for the next movie.]]
* ShoutOut: The sub-plot of a human female displaying enough courage and prowess (namely by killing a couple of Xenomorphs) 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 first Alien vs. Predator comic (and the ''Alien vs Predator: Prey'' novelization), 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: Surprisingly averted in the first movie. The opening shot in space is completely silent apart from the soundtrack. The only noise heard comes from the scenes inside of the Predator ship.
* StatOVision: A predator decides not to kill [[spoiler:[[NotWorthKilling Weyland because it can see that he's already dying of cancer.]] [[HeroicSacrifice Then Weyland improvises a flamethrower to buy the others more time...]]]]
* TooDumbToLive:
** Pretty much everybody, but a few stand out. Adele takes a little too long to put "sacrifical chamber" and "mysterious eggs emerging besides ancient skeletons" together, and doesn't act fast enough to save herself from the facehugger. Miller manages to kill an attacking facehugger but wastes bullets on the corpse (not that his already limited ammunition would have been much help against an entire ''room'' of facehuggers).
** 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 speaker right (because no ''human'' gun winds up being of any use, and the Predators focus mostly on melee weapons in this series).
** 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.
** All of the Predators really. They were there to hunt Xenomorphs, not humans. Yet they stop to kill the drill-team on the surface (even going so far as stringing them up for skinning) even though they should realize that time is of the essence with curious humans poking around the temple. Had they not taken this senseless detour in their priorities, they could have gotten to the plasma casters before they were taken by the expedition; and the hunt would have likely gone very differently. Justified in that if Predators weren't that fanatic about hunting they wouldn't be in that mess to begin with. Possibly justified, as it's hinted this is the first hunt for these particular Predators, so it's likely a rookie mistake.
* TookALevelInBadass: Lex.
* VasquezAlwaysDies: Despite the source movie being the TropeNamer, it's averted. The lead is equally as badass as the "Vasquez" clone (who does die first).
%% * VersusTitle
* VillainousRescue: As a Predator is about to kill Lex, a Xenomorph appears out of the shadows and impales the hunter with its tail, inadvertently saving Lex.
* TheWorfEffect: As with the ''Predator'' movies, the hunters are shown to be unstoppable with their superior technology against humans, having killing several of them in the first half of the movie. Then, a single Drone killed two of them, reminding the audience that the Xenomorphs are just as dangerous (if not more) as the Yautjas. Granted that these Predators are young-blood and are not properly equipped.
* WorthyOpponent: Having seen her killing two Aliens, Scar sees her as a warrior and branded her with the same marking as him. [[spoiler:After the rest of the clan arrives, the Ancient Predator rewards her with his spear as a sign of respect]].
* 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 happened, and he spends the rest of the film acting as if he didn't know about the Alien inside of him.]]
** [[FridgeBrilliance Justifed, as Kane from the original Alien only remembers "some horrible dream about smothering,"]] [[ShownTheirWork hinting that being facehugged messes with short-term memory, leaving the event itself a blank.]] A useful trait for a species that breeds by parasitic reproduction with often sapient hosts.
** An alternate interpretation is that Scar likely knew exactly what happened to him (as he would have no doubt done his homework on the prey he was there to hunt); and was simply gambling that he would be able to have the xenomorph removed when his people picked him up. Apparently a scene was planned but never filmed of the mortally wounded Scar stabbing himself with his dagger to kill the xenomorph gestating inside.
