''Alien Nation'' (1988) is a [[BuddyCopShow Buddy Cop movie]] with a {{Sitcom}} twist: the minority partner is a space alien, part of a ship of "Newcomers" who ended up on Earth when the slave ship they were being transported on crash-landed. After Det. Matthew Sykes' partner is killed in a shootout, he is partnered with Sam Francisco (whom he insists on calling "George"), the first Newcomer detective. While investigating the death of Sykes' partner, they uncover a dangerous Newcomer drug.

The film was adapted into the 1989 TV series ''Series/AlienNation'', which lasted for one season and five TV movies.

As of 2015, a planned reboot of the film has been [[http://ca.ign.com/articles/2015/03/26/alien-nation-movie-reboot-in-the-works announced]], but few details are known.

!!Provides examples of:

* AdaptiveAbility: The Newcomers were a slave race bred to adapt to ''any'' environment; Earth is a tough one for them, though...
* AlienAmongUs: The Tenctonese[=/=]Newcomers are refugees and slaves. In this case it was over 250,000 aliens, who form their own community in Los Angeles. Therefore the cultural misunderstandings went both ways, as humans learned to deal with odd newcomer traditions.
* AlienLunch
* AppliedPhlebotinum
* BallsOfSteel: Sykes groin-kicks an alien, who laughs it off. Later, George tells him that he'll get the result he was looking for by hitting an alien in the side of the torso. Sykes tries this out later, and it proves as effective as a groin shot.
* BizarreAlienBiology: Saltwater burns Newcomers, they also require any meats they consume to be raw, can get drunk on sour milk, require a member of their third sex to catalyze pregnancy, and have a nerve cluster under their arm that has the same effect on them as a GroinAttack
* BlackDudeDiesFirst: Sykes's black partner dies in the opening.
* BrakeAngrily
* BuddyCopShow
* BulletProofVest: Worn by Sykes' partner during the armed robbery. It doesn't help at all.
* CoolGuns: One of the first film appearances of the Freedom Arms .454 Casull Magnum, at that time, the world's most powerful handgun.
* ConcealmentEqualsCover: Played with: Bullets pierce all the way through a car (and the guy hiding behind it), but are revealed to be special, industrial-strength {{Dakka}}.
* DeadPartner: Bill Tuggle.
* DrugsAreBad: The Newcomers' former alien overlords kept them under control by feeding them a blue substance. Sam/George Francisco keeps this a secret from his human buddy-cop partner because he fears what humanity would do to the Newcomers if we ever found out they were a bunch of drug addicts. Near the end of the movie, a rogue Newcomer consumes an entire giant tube full of the concentrated drug and [[spoiler:turns into a mutated rampaging monster.]]
* DrunkOnMilk: The Newcomers.
* ExploitedImmunity: A Newcomer drug lord has his human henchmen pull another Newcomer into the ocean to kill him.
* FantasticDrug: The drug that was used to pacify Newcomers, and an overdose causes them to turn into a monster. The BigBad tells Sykes that even though it's "more powerful than any human drug", it's still just an ''alien'' drug, and legally, it might as well be grape jelly.
* FantasticRacism
** Obviously, some humans resent the Tentonese. Some of them are called Purists and untertake militant actions and political subterfuge against the aliens. But the Tenctonese also harbor FantasticRacism against the Eenos, a caste of waste extraction workers whom they consider a subspecies. Even on Earth, the Eenos continue to work in sewage processing.
* FantasticSlur: Human bigots refer to Newcomers as "slags" or "spongeheads".
* ForeignCussWord: Inverted, in that in the Tenctonese language, "Sykes" roughly translates as "excrement cranium" ("shithead"). However, it's pronounced differently ("see-ikes") than his name is normally pronounced ("sikes").
* GRatedDrug: Newcomers get intoxicated on sour milk. The yeast-fermented stuff that we humans prefer has no effect on them.
* HandCannon: Sykes upgrades from his police-issue sidearm to a Freedom Arms Model 83, a 5-round .454 Casull revolver, in order to combat the Newcomer gang that killed his partner. At the time the film was made, this was the most powerful handgun/cartridge commercially available.
* HumanOutsideAlienInside: Although they look moderately similar to humans, Tenctonese cannot metabolize cooked protein, so most of their diet consists of raw animals, they also have two "hearts" (not really hearts, but as close as they get to one).
* HumansAreSpecial: Many of the Tectonese, especially George, believe this because they welcomed The Newcomers into their world, gave total freedom to a species bred to be perfect slaves, and asked no more of them then they would themselves. Racism aside that's pretty damn impressive.
* HumansAreTheRealMonsters: A lot of them are racist towards the Newcomers, however the movie runs with NotSoDifferent.
* ICantBelieveItsNotHeroin: The Newcomer heroin is a blue substance that tastes like detergent to humans, but has the (nearly) same or a stronger effect on Tenctonese than heroin would on humans, including deadly side effects. This dope was used to keep them docile as slaves, more work equaled more dope, to the bitter end, literally. Overdosing on it turns Newcomers into nigh-unstoppable rage monsters. George is terrified if the substance coming back and is prepared to [[TakingYouWithMe kill himself]] to wipe it out again.
* InsectoidAliens: [[PlayingWithATrope Played with.]] In the pilot for the TV series, the Purists pull a hoax involving an insectoid alien in order to provoke fear and mistrust among the general population toward the Tenctonese. Later, a Tentonese fetus has insectoid characteristics, and it's remarked that "Ontogeny recapitulates phylogeny," implying an insectoid ancestry for the Tenctonese. Finally, Tenctonese mutants in one of the movies have an insect-like appearance and lifestyle.
* InsufficientlyAdvancedAlien: As a slave race, that wasn't their ship or their tech. Thus, they end up no more advanced than humanity.
* MinorCrimeRevealsMajorPlot: Murder of a cop during a robbery -> re-introducing a devastating alien drug.
* NicknamingTheEnemy: Bigots refer to the Newcomers as "Slags". There's also "Spongeheads."
** Some Tentonese refer to humans as "Terts."
* NoBiochemicalBarriers: The Newcomers may eat weird stuff, like raw beaver, but it's all Earth-originated.
* OminousFloatingSpaceship: The Newcomers' spaceship for its first appearance.
* PoliceProcedural: With a twist.
* ProductPlacement: Pepsi, Bartles and James, Tic Tacs - a lot of placement in the store robbery early in the movie.
* PunBasedTitle: Alien nation; alienation.[[note]]The original title was ''Alien Heat'', which was fairly uninspired.[[/note]]
* PunnyName: Most of the Newcomers, including George (whose human name officially was "[[SanFrancisco Sam Francisco]]"). Explained as the immigration authorities getting burned out assigning names to the Newcomers and resorting to a form of sarcastic humor.
* PunyEarthlings: The Newcomers have great strength, stamina, durability, ability to survive in environments humans can't, extra hearts, and if they overdose on an [[FantasticDrug extraterrestrial]] [[PsychoSerum narcotic]], they transform into [[AxCrazy murderous, supercharged berserkers]]. But they do have a [[WeaksauceWeakness strange weakness]] or two: [[KillItWithWater water with high salinity burns them like sulphuric acid burns naked mole rats]] and they get [[AlienLunch stinking drunk from sour milk]].
* RevolversAreJustBetter: After nearly being killed when his 9 mm Beretta proves inadequate at stopping a drugged up Newcomer, Det. Sykes switches to a .454 Casul HandCannon.
* RubberForeheadAliens
* StarfishLanguage: Tenctonese.
* SuperStrength: The Newcomers were bred for it.
* TwentyMinutesIntoTheFuture: Released in 1988, it represents the 1990's.
* WeaksauceWeakness: Newcomer flesh dissolves on contact with ''[[KillItWithWater salt water]].''
* WhateverHappenedToTheMouse: The Newcomer coroner's assistant recognizes the signs of the drug and after dropping off the report for George goes home early. He has no bearing on the rest of the film.
* WunzaPlot: Wunza human, wunza former alien slave. TheyFightCrime.
* YourMom: A really nasty Tenctonese insult: "Your mother mates out of season," which is probably akin to, "Your mother's a whore."
