Some shows love playing genre conventions, a FantasyKitchenSink will have everything in the mythological handbook and then some, TropeOverdosed works will keep adding tropes so long as they run, and then there are even shows [[TropeMaker that make new tropes.]]

These are not those shows. (Or can they be?)

A Sci-Fi Kitchen Sink is for all intents and purposes the playground of Science Fiction Tropes and everything associated with them. Have an ArtificialIntelligence construct able to run the CoolStarship? It makes you coffee in the morning. HumongousMecha? You walked by several on the way to work. FasterThanLightTravel? [[CasualInterstellarTravel Totally mastered to the point where even Joe Penniless can get a ride to the stars.]] [[BeamSpam Laser and particle beams as weapons?]] Everybody and their dog has one. The list of possible areas seems to be endless.

A good way to tell if a work is a Sci-Fi Kitchen Sink, is ask three questions. Is it in the SciFi genre? [[MohsScaleOfSciFiHardness Is it softer than reality by a wide margin according to the scale?]] Does it use all or much of the stuff in the genre of SciFi and not [[LampshadeHanging Hang A Lampshade]] on it? Answer yes to all three and you likely are dealing with a Sci-Fi Kitchen Sink.

Popular in SpaceOpera. Also popular in MegaCrossover fanfic. Naturally compare FantasyKitchenSink; when both sinks are combined, it becomes ScienceFantasy. See also StandardSciFiSetting, a particularly popular instance of Sci-Fi Kitchen Sink.

!!Examples:

[[foldercontrol]]

[[folder:Film]]
* ''Franchise/StarWars'' is a kitchen sink of MilitaryScienceFiction, SpaceOpera and HighFantasy tropes. Thousands of different races, including [[OurVampiresAreDifferent several vampires]], [[RaptorAttack space velociraptors]], insect {{hive mind}}s, {{Energy Being}}s that might as well be ghosts, and three different [[ZombieApocalypse zombie types]]. Everything from massive ship-to-ship battles, to space fighters, to {{Humongous Mecha}}. Hacking (called slicing) is on, AI and robots galore, there's time travel (albeit by accident), FTL, and so on.
* The ''Franchise/{{Godzilla}}'' movies increasingly became this especially into the Heisei series, featuring aliens, space travel, giant robots, androids, time travel, and various other scifi shenanigans.
[[/folder]]

[[folder:Literature]]
* ''Literature/{{Spectral Shadows}}'' could qualify for this. There's a {{Mad Scientist}}, a world in a time that takes place {{After the End}}, there's {{Time Travel}}, {{Funny Animal}}s that evolved from genetic slag due to weaponized acid rain, there's an intergalactic empire of {{Space Pirates}}, android funny animals, a [[{{TheMatrix}} virtual reality rpg where one can learn powers at the expense of feeling any and all pain]], world warping powers, a space ship that can travel time and space, humongous mechas, and more.
* In the universe of [[Creator/IainBanks Iain M. Banks]]'s hyper-advanced people, Literature/TheCulture, there's everything from dystopian ultra-capitalist planets, small debauched backwaters, "Sublimed" civilisations living in entire other dimensions, neglectful precursors, {{Proud Warrior Race}}s, post-singularity communist civs...well, you get the idea. The fact that this is just a very incomplete list of some of the civilisation types should tip you off to the fact that this series mixes-and-matches an awful lot of sci-fi tropes. Tech levels vary right alongside the civilisations, although we rarely see a world a great deal less developed than present day Earth. Expect to see SciFiWritersHaveNoSenseOfScale stunningly averted, in both range and size of ships, drones, space battles, androids, sentient space-suits, conspiracies and counter-conspiracies.
* Literature/PerryRhodan is running for over 50 years now and did start with UsefulNotes/TheSpaceRace and then features things like AncientAstronauts, SufficientlyAdvancedAlien, AscendToAHigherPlaneOfExistence, TheBattlestar, CosmicChessGame, LensmanArmsRace, OrderVersusChaos, and and ... and we have not nearly covered everything in the first one hundred books.
* In ''Literature/DragonsLexiconTriumvirate'', there are cyborg dragons, Technoknights, computers, and nukes, [[Film/TheWizardOfOz oh my!]]
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/DoctorWho'', by virtue of being an extreme LongRunner with a massive [[ExpandedUniverse expanded]] [[Franchise/{{Whoniverse}} universe]], ranges through the entirety of time and space. After 50+ years of stories, that's a lot of sci-fi ideas - you've got high-tech military forces battling witches and ancient astral demons, mixed in with genocidal robots and sentient nanoswarms.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/{{Warhammer 40000}}'' - sometimes it's like each army is there to be a representative of a different sort of science fiction. Your SpaceMarines are your, unsurprisingly, post-[[Creator/RobertAHeinlein Heinleinian]] SpaceMarines infused with knights and religious fervor, the Imperium fields big ''TableTop/BattleTech''-style mechs, the Imperial Guard are essentially ''Franchise/StarWars''' stormtroopers (which are even referenced by name!) with several different flavors, ranging from UsefulNotes/WorldWarI trench warfare (the Death Korps of Krieg) to [[UsefulNotes/TheVietnamWar Vietnam]]-style survivalists (Catachans), Tyranids are books are about BugWar, Tau are {{animesque}} mecha and firepower and TheFederation, Eldar are ClarksThirdLaw SufficientlyAdvancedAliens that lean heavily towards {{ninja}}-style weapons (everything they fire are shurikens), rely on psychic powers, and take the traditional Japanese leaning, spaceship battles feel like they come out of the ''Literature/HonorHarrington'' universe, Necrons are ''Franchise/{{Terminator}}'' and so on. If anybody want to write about or parody a certain type of science fiction, then they can.
* ''TabletopGame/{{Traveller}}'' is the first RPG to truly mix every science fiction trope into one setting. The subgenre can change depending on where your character is located in the galaxy. If they're constantly traveling through space by ship, it's a Space Opera (which is what the game was originally advertised as). If your character is stranded on a primitive world, far away from civilized space, it's a Planetary Romance. If you're on a high-tech planet where everything is connected to the internet, it becomes Cyberpunk. When you go out into the Spinward territories, you're in a Space Western. Even a Post-Apocalyptic setting is possible if it's set between the Second and Third Imperium eras.
* ''TabletopGame/{{Trinity}}'' was launched as one of these as well. You want {{Cyberpunk}}? America's [[OneNationUnderCopyright corporate-owned]] and full of {{technopath}}s. You want wasteland? UsefulNotes/{{Paris}} and a huge chunk of the surrounding land got nuked. You want SpaceOpera? Mankind's made first contact and is currently involved in political dealings with at least three different species. You want PsychicPowers? What flavor do you want them in?
* ''TabletopGame/{{Infinity}}'' is much the same - Cyberpunk tropes happily contained in [=PanOceania=]'s warring hypercorps and corporate troops alongside Space Knights, European troopers in armor heavily inspired by ''Manga/{{Appleseed}}'''s E-SWAT, and soldiers that are heavily based on the [[FilmOfTheBook film version]] of ''Film/StarshipTroopers'' (down to the "Would you like to know more?" CatchPhrase), space Samurai, ninja, and sprawling animeesque and East Asian sci-fi in Yu Jing, a UsedFuture in the Ariadnans (who are mostly military-fiction, unchanged 20th[=/=]21st century units wielding rifles that wouldn't be out of place in a modern setting) and the Nomads (who experiment with bioengineering, giving us Space {{Catgirl}}s and put the punk in cyberpunk with anarchist sci-fi tropes and punk-inspired designs, with futuristic Roller Derby gals as a unit), an America left devastated by a nanoswarm, becoming a ''Franchise/MadMax''-esque [[AfterTheEnd apocalyptic wasteland]], ''Literature/{{Dune}}''-esque Haqqislam units who literally control the Spice flow, ''Franchise/{{Halo}}''-esque Morats hired by an insane conglomerate of [=AI=]s, bio-tech, organic Tohaa - all watched by a TronLines-and-[[EverythingIsAnIpodInTheFuture Apple-esque]] faction, ALEPH, who attempt to bring order to the human factions.
[[/folder]]

[[folder:Video Games]]
* The ''Franchise/{{Halo}}'' series, including its ExpandedUniverse. It has HumongousMecha, FasterThanLightTravel, ArtificialIntelligence, SpaceMarines, {{Precursors}}, etc. While the weirder aspects of SciFi like PsychicPowers or various {{Negative Space Wedgie}}s haven't show up in the games (although the [[TheVirus Flood]] HiveMind, Slipspace anomalies, and the [[spoiler:Ur-Didact's]] [[MagicFromTechnology gravity control powers]] come close), ''Literature/TheForerunnerSaga'' dips into that territory [[spoiler:by going the CosmicHorrorStory route, complete with {{Eldritch Starship}}s, GeniusLoci, and a SentientCosmicForce which allows technology to be made of ''thought'']].
* ''VideoGame/{{Starcraft}}'': Everything can travel faster than light via PsychicPowers, science or biological creatures able to do so on their own! AI exists but is lower key, {{Starfighter}}s abound as do HumongousMecha and [[TankGoodness Tanks]] and more.
* ''VideoGame/{{Stellaris}}'' seems aiming to get every and all Sci-Fi tropes. There are [[FasterThanLightTravel faster-than-light engines]] in HyperspaceLanes, [[AnotherDimension Jump]] and [[OurWormholesAreDifferent Wormhole]] flavour as available means of travel. There are {{Artificial Intelligence}}s, [[AIIsACrapshoot going wild]] and not, [[GalacticSuperpower Ancient Star Empires]], alive [[{{Precursors}} and not]], [[SpaceWhale Space Jellyfish]], [[EldritchAbomination Eldritch Abominations]], [[HordeOfAlienLocusts Hordes Of Alien Locusts]], evil {{Energy Being}}s and the aforementioned AI going wild as crisis super factions, and that's just the core game.
** The expansions really ramp up the ante: ''Leviathans'' gives more [[EldritchAbomination Eldritch Abominations]], including ghost-like things that come straight out of Pulsars, a giant Space Dragon (and with luck you can even hatch your own, smaller, Space Dragon), and a thing called a '''Dimensional Horror'''. You also get NPC {{Space Station}}s that variably act as advisors, artists or traders [[RecycledInSpace in space.]]
** ''Utopia'' adds megastructures, which includes making your own habitats, ring worlds and even {{Dyson Sphere}}s. If that's not your thing, there is always genetic modification, cybernetics and BrainUploading, or researching PsychicPowers.
** ''Synthetic Dawn'' allows you to play as an empire of Machines, either in [[Franchise/MassEffect Geth]], [[Franchise/{{Terminator}} Terminator]], [[Franchise/StarTrek Borg]] or [[Literature/TheCulture Minds]] flavour. You can even find a fallen machine empire, who may help you, or may turn crazy.
** ''Apocalypse'' adds super-ships called Titans and {{Planet Destroyer}}s called Collossi. The latter come in regular EarthShatteringKaboom flavour, but variably also [[FateWorseThanDeath sealed-away shield]], [[EasyEvangelism God Ray]] or [[CyberneticsEatYourSoul forced cyborgisation]].
* ''VideoGame/{{Fallout}}'' could be called either an post-apocalypse kitchen sink or a sink that focuses on sci-fi elements popular in TheFifties. You've got radiation-warped mutants, immortal zombies that gradually turn feral as their minds break down, robots ranging from Robby of ''Film/ForbiddenPlanet'' to ''Terminator''-esque synths, one or two LittleGreenMen, drugs that bestow psychic powers, [[BrainInAJar disembodied living brains]], and even a few people who bring justice to the wasteland by dressing up as ancient superheroes.
[[/folder]]

[[folder:Webcomics]]
* ''Webcomic/AxeCop'' uses a wide variety of sci-fi tropes in creative (and frequently [[CrazyAwesome ridiculous]]) ways.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/{{Futurama}}'': Everything that exists in the Sci Fi Writer's Handbook exists here plus a heaping helping of RuleOfFunny and ItRunsOnNonsensoleum. WordOfGod says in the DVDCommentary that they realized just how far down this rabbit hole they'd gone when they agonized over whether it was okay to feature [[FantasyKitchenSink a wizard]] alongside everything else, they did, and nobody in the audience blinked.
* ''WesternAnimation/PhineasAndFerb'': Given that the show is about boys building impossibly advanced technology, this is a given. It has had evil scientists, spy organizations, aliens, TimeTravel, RidiculouslyHumanRobots, advanced nanotechnology, superheroes and villains (including from the Franchise/MarvelUniverse, which is a SFKS all its own), {{Teleportation}}, holograms, supercomputers, AnotherDimension, and sentient AIs (good and bad), to name a few.
