->"''What if you could find brand new worlds, right here on Earth, where anything is possible? Same planet, different dimension. I've found the gateway.''"

''Sliders'' (1995-2000) is a ScienceFiction show about four people who try out a device for traveling to {{Alternate Universe}}s, then get lost and spend the remainder of the series trying to get back to their world of origin. It started out as an extremely fun AdventureSeries revolving around the "What If...?, scenarios offered by alternate worlds (''"What if the US lost World War II? What if dinosaurs didn't go extinct? What if you were born the opposite sex?"'' etc.), but when Creator/{{Fox}} executives took over, putting in their own man and reducing the original producers to "executive consultant" level (and apparently not ''consulting'' them much), the series steadily self-destructed, most of its episodes being ripoffs of movies that were popular at the time, and becoming dark and mean-spirited, dumping most of the characters (via death or worse) and developing a MythArc about a race of killer-ape-descended villains called 'Kromaggs' which eventually took over the show. The first and second seasons are generally considered the series' best, with the mid third season marking the start of the ExecutiveMeddling described above, which led to the series' decline.

The surprisingly competent final episode ended with a CliffHanger meant to try and push the SciFiChannel into giving them a 6th season; it had been clear from the start of production on Season 5 that Sci Fi intended to cancel it, having picked it up to get its viewers to watch their new shows. The attempt failed; Season 5's ratings actually were good enough that it normally would've been renewed, but Sci Fi had committed to other shows already.

Over the years, the series has been slowly released on DVD. Season 5 was finally released January 2012. Reruns can currently be seen on TheHub, and all 5 seasons are currently on Netflix.

!!Trope-based episodes:

* AboveTheInfluence: In "Love Gods," a man is hiding from a country of beautiful women wanting him to fertilize them because he wants only his not-pretty-enough, not-young-enough partner. Awww.
* ApocalypseAnarchy: This is the story of several episodes, particularly "Last Days" and "The Exodus, Part 1," in which the end is near and society has degenerated in this way.
* AdventureTowns: Actually, it's (almost) always the same city (''UseFulNotes/{{San Francisco}}''), but due to our heroes travelling from one reality to another, they find themselves in a different situation each episode.
* AlternateHistoryWank: Several episodes dealt with other countries becoming major world powers.
** The first episode had Russia as the dominant world power, after capitalism fell.
** Another episode had Saddam Hussein using a bioweapon that attacked the Y chromosome, wiping out much of the male population of the Earth. Because they were furthest from the epicenter and least affected, Australia became the dominant world power on that Earth.
** Still another had the American Revolution fail, and America wound up as a part of the VERY large British Empire.
* ANaziByAnyOtherName: Kromagg military culture resembles this right down to their uniforms.

* BrassBalls: "The Exodus, Part 1." Quinn said to Maggie that he could hear her "brass balls" clink.
* ByTheEyesOfTheBlind: "Gillian of the Spirits"
* ChemicalMessiah:
** "Fever"--The crew visit an alternate Earth decimated by plague. Eventually they realize that antibiotics were never discovered in this timeline, so Arturo creates penicillin, which becomes the Chemical Messiah for this world.

* DrivenToSuicide: "The Chasm"
* ETGaveUsWiFi: "The Return of Maggie Beckett" -- The Roswell crash did happen, but instead of being covered up, a trade agreement was struck. TheGreys gave Earth new technologies, allowing for significant advances. This included DNA advances, allowing for a HalfHumanHybrid to appear.
* FakeShemp: The shots from above during the first episode of the last season, after Jerry O'Connell left the show.
* FinalSolution: "Prophets and Loss"
* FindTheCure: "Fever"
* FlatlinePlotline: "Slide Like an Egyptian"
* FloatingContinent: "Season's Greedings"
* FutureImperfect: "Dust"
* {{Gendercide}}: "Love Gods"
* GenderRarityValue: "Love Gods" again.
* GrandTheftMe: "Dragonslide"
* HauntedHouse: "The Alternateville Horror"
* IHatePastMe / MyFutureSelfAndMe: "The Guardian" -- While not outright [[TimeTravel time traveling]], the Sliders travel to a world over a decade behind theirs. Quinn encounters his past self shortly after the death of his father, and struggles to help his younger double learn [[SetRightWhatOnceWentWrong to defend himself against a bully rather than lash out in anger like he himself did]].
* InvadedStatesOfAmerica: The second episode showed a Soviet-occupied United States.
* InvisibleMainCharacter: "Gillian of the Spirits"
* JourneyToTheCenterOfTheMind: "The Dream Masters" (which, incidentally, is the only episode with no sliding).
* JustBeforeTheEnd / ScrewTheRulesItsTheApocalypse: "Last Days," "The Exodus, Part 1."
* KangarooCourt: "Dead Man Sliding" -- The Sliders end up in a world where the justice system has become a GameShow and lawyers are banned. When Arturo tries to object to this attitude that Quinn may as well be convicted, the host warns him not to try any other "lawyer tricks."
** In "The Young and the Relentless," Arturo uses the expression "kangaroo court" to describe his treatment on an Earth where everyone over 30 is subject to a nightly curfew.
* KissMeImVirtual: "Virtual Slide"
* LadyLand: "The Weaker Sex," "Love Gods"
* LightningCanDoAnything: "Gillian of the Spirits"
* LotteryOfDoom: "Luck of the Draw"
* LotusEaterMachine: "Virtual Slide," "The Chasm."
* LovePotion: "Dragonslide" -- Rembrandt attempts to use this on a world of magic to make a double of an old love fall for him. Instead, it makes him fall in love with [[spoiler:Wade]].
* LotteryOfDoom: "Luck of the Draw"
* {{Nanomachines}}: "New Gods for Old"
* NeverSleepAgain: "The Dream Masters" depicts a world ruled by a sinister cabal that can kill people in their dreams.
* NewOldWest: "The Good, the Bad and the Wealthy"
* [[ElvisLives Rembrandt Lives]]: In an episode where that world's Rembrandt Brown was a hugely successful singer who died young, Rembrandt Prime decides to "come out of hiding" and take over where he left off. But then the "real" Rembrandt decides to really come out of his self-imposed exile, taking over from Rembrandt Prime at his comeback concert and declaring Rembrandt Prime "the greatest [[ElvisImpersonator Rembrandt Brown impersonator]] in the world."
* RichardNixonTheUsedCarSalesman: In "Stoker," which takes place in a world where vampires are real, Nixon is said to be the worst vampire of them all, equivalent to the legend of Dracula on Earth Prime, only real.
* SandWorm: "Paradise Lost"
* ScienceIsBad: The world in "Gillian of the Spirits" came to that conclusion after Hiroshima, resulting in government-enforced stagnation. That universe's Quinn died of polio as a result of this.
* TyrannosaurusRex: "In Dino Veritas," "Dinoslide."
* VideoGameCrueltyPotential: In "A Thousand Deaths," the team arrives on a world with very advanced, holodeck-like video games. Rembrandt and Mallory play to win, but lose interest when they find all the other players are just interested in killing the VR characters. It gets worse when they discover that the video designers replicated human reaction by integrating (unwilling) human hosts like Maggie and Diana into the games. Each VR death is very real and a host can be used a thousand times.
* WholeEpisodeFlashback: "Post Traumatic Slide Syndrome," "The Last of Eden."
** The latter wasn't intended as a flashback episode. [[spoiler:Because Fox mistakenly scheduled it ''after'' "The Exodus, Part 2" in which Arturo is killed, they had Universal film a brief prologue with Wade and Rembrandt in which it's established that Wade's bothered by memories of the events of "The Last of Eden."]]

----
!!This series provides examples of:

* AbortedArc: With maybe one or two exceptions, none of the multi-episode arcs this show started were ever resolved.
* ActionGirl: Maggie, former soldier.
* AdventureTowns
* AgentScully: Arturo
* AlienSky
* AlliterativeName: Wade Wells.
* AlternateHistory: Most of the worlds visited fall into this category.
* AlternateUniverse: To both its fans and its critics, the series is the most extensive exploration of this trope on American TV.
* AlwaysChaoticEvil: The Kromaggs.
** There were a few exceptions, like that disgraced Kromagg leader who was in charge of the human atomizer thing in "Common Ground."
* AmazingFreakingGrace: The end of the pilot, sung by Rembrandt.
* AndIMustScream: The altered "Eddies" in the fourth season episode "California Reich."
** In "A Thousand Deaths," the human hosts used to drive the simulations. They can die up to a thousand times in the games, and they're fully aware of what is happening to them.
* AndStarring: John Rhys-Davies as Arturo.
* ArbitrarySkepticism: In "The Alternateville Horror," Colin claims to have seen a ghost, but is laughed off by the others for even thinking such a thing. [[spoiler:They are no ghosts; just doubles of the Sliders trapped on another plane as a result of a sliding mishap.]] Aside from the many strange things they've seen in their journeys, this is particularly ridiculous when you consider that Quinn himself was rendered ghost-like in Season 2's "Gillian of the Spirits" and could only be seen by one person. [[spoiler:Considering that, Quinn and Rembrandt should've been more receptive to what Colin was talking about.]]
** Arturo seemed to run on this trope. Being a college professor, he was always intent on suggesting a simple, logical explanation to strange incidents.
** Played with in "The Other Slide of Darkness," where both Rembrandt and Maggie express disbelief in the superstitious beliefs expressed by the locals. Rembrandt's disbelief stems from a personal tragedy; Maggie's, however, is played straight, which gets her snapped at by the more experienced Wade.
** {{Lampshaded}} by Rembrandt in Season 5's "Please Press One":
--->"Sliders Rule #11: Never rule out the obvious no matter how weird."
* BabyFactory: On some worlds women (or men) are forced into this trope due to population problems.
* BetterThanSex: In the first episode, Wade claimed that sliding is better than sex.
--> '''Arturo:''' Well, I wouldn't go ''that'' far.
* BigBad: Rickman in Season 3, the Kromaggs in the fourth and fifth seasons.
* BigNo
* BlatantLies: "We're from Canada."
* BrilliantButLazy: Quinn. Hence the reason why Arturo is initially so ''[[GreenEyedMonster pissed]]'' to discover the genius who invented wormhole travel, is the same slacker who never bothers to hand his homework assignments in on time!
* CaliforniaCollapse: In the Season 3 finale "This Slide of Darkness," they slide into a world where California has broken up into islands.
* CanonDiscontinuity: Season 3's "The Other Slide of Darkness" stated that Quinn's double from the first episode gave the Kromaggs the sliding equation and is responsible for the Dynasty's activities. Season 4 onward ignored this development, which some felt didn't fit into established continuity in the first place.
* CaptainsLog: Wade's diary, Quinn's videotapes.
* TheCastShowoff: Cleavant Derricks has a beautiful singing voice, showcased in several episodes. Justified, in that Rembrandt was a professional musician on Earth Prime.
** This was used to expose Rembrandt as a fraud in one world; that world's version was royalty and tone-deaf.
* CelebrityParadox: On the episode "Data World," Rembrandt said "What is this, ''Scream 3''?" Guess which one of his co-stars got killed (in character) in ''Scream 2''?
* ChangelingFantasy
* CharacterDevelopment: Rembrandt. He goes from a DirtyCoward concerned only with himself to an [[TheEveryman everyman]] who cares for [[TrueCompanions his surrogate family]] to TeamDad over the course of five seasons. (Being the only cast member to stay for all five seasons certainly helps.)
* ChronicHeroSyndrome: Quinn
* CrapsackWorld: As the Sliders visit many worlds, they encountered quite a few of these, beginning with the [[DeathWorld Ice Age world]] in the pilot episode.
* CityOfAdventure: For the first two seasons, UsefulNotes/SanFrancisco, in nearly all of the worlds, is somehow majorly relevant to the world at large.
* ComicBookAdaptation: Circa Season 3, Acclaim Comics produced ten issues with various creative teams (with the eighth, ''Narcotica'', being written by Jerry O'Connell). A script for an eleventh issue (plus several pages of artwork) was completed and several future ideas (including a ''QuantumLeap'' {{Crossover}}) were being developed, but declining sales led to cancellation.
* ContaminationSituation: In "Fever," Wade becomes infected with a plague.
* CutShort
* DeadGuyJunior: If dialogue that implies Maggie Beckett is [[QuantumLeap Sam Beckett]]'s niece is taken seriously, this makes her a DeadGuyJunior. Maggie was the name of a news reporter who died on a mission in Vietnam while working with Sam's brother Tom.
* DeadlyEuphemism
* DisneyVillainDeath: [[spoiler:Rickman dove head-first off a cliff in a failed attempt to follow Rembrandt and Wade through a wormhole.]]
* DownerEnding: "The Breeder," which [[spoiler:has the doctor being overtaken by the symbiote creature. As they have no time, the Sliders choose to slide out with a weakened Maggie rather than try to help. With the Sliders gone and the doctor overtaken, the symbiote is free to continue its goals unimpeded.]]
** "The Dying Fields": [[spoiler:The sympathetic Humagg soldier is murdered by her lover for betraying the Kromaggs. Worse, the Sliders aren't able to save the remaining human captives and the camp stays open, meaning business will continue as usual.]]
** "Applied Physics": [[spoiler:Diana attempts to make her double's life better with Geiger's help but, among other changes, she winds up erasing her double's daughter from existence. The team has to slide before she can set things right.]]
** "Strangers and Comrades": [[spoiler:Rembrandt learns the quest to find Michael Mallory's anti-Kromagg weapon was all for nothing. Turns out the weapon trashed Kromagg Prime's environment a month after it was used, and it would do the same to Earth Prime. Rembrandt is left lamenting that he's run out of chances.]]
* DramaticShattering
* TheDrifter
* DroppedABridgeOnHim: Almost everybody, eventually. See also PutOnABus.
* {{Dystopia}}
* ElectricTorture
* TheEmpire: The Kromagg Dynasty
* EruditeStoner: Conrad Bennish, Jr.
* EveryoneMeetsEveryone
* EvilCounterpart: Rickman
* EvilTwin: Numerous evil doubles. For some reason, Arturo's doubles were almost always bad news.
** OppositeSexClone: Logan St. Clair is a [[spoiler:female double of Quinn]] in "Double Cross."
* EyeScream: [[spoiler:Kromaggs really love human eyeballs.]]
* FailureIsTheOnlyOption
* FakeoutEscape: Attempted unsuccessfully in the Western-themed episode "Way Out West." It turns out that [[spoiler:Kromaggs have their own westerns]].
* {{Fanservice}}: Quinn. Season 3's "Electric Twister Acid Test" features an interrogation in which Quinn has his shirt off for no reason.
* FinalSeasonCasting: While the show had already substituted two characters by that point, it lost ''half of its main cast including the main protagonist'' between Seasons 4 and 5.
* FollowTheLeader
* ForWantOfANail
* FourTemperamentEnsemble: Quinn is sanguine, Arturo is choleric, Rembrandt is melancholic and Wade is phlegmatic.
* GaveUpTooSoon: In the episode "Into the Mystic," the characters only have a few seconds to decide whether or not to stay on the latest parallel Earth they've landed on. To see if it's their home or not, Quinn tries a fence, knowing it is always squeaky ([[CallBack something he does in the pilot]]), and it doesn't squeak. After they leave, a gardener with an oil can comes into view.
** In their defense, didn't they also see a newspaper headline about a sports team winning a championship; a team which in reality had moved to a new city since the start of the series or was that a different episode.
*** And since they had been gone, O.J. Simpson had been arrested and was still on trial, they had trouble believing that the world could have changed so much in just two years.
* GiantSpider: In the episode "Summer of Love," the Sliders first land on a world where the United States has been mostly devastated by these. A mix of a spider and wasp (yes, [[NightmareFuel flying spiders the size of your head]]), they were genetically engineered for pest control--namely the actual killer bees... And ironically enough, a few queens escaped from the labs and suddenly the cure became a lot worse than the plague.
** In "Rules of the Game," one of the death traps sees Rembrandt stuck to a metal web and being threatened by three robotic spiders.
* GirlOfTheWeek
* GirlsWithMoustaches: In one episode, the characters travel to a world where women have mustaches. Rembrandt complains about how it feels to kiss a woman with a mustache and Wade comments that now he knows how women feel.
* GloryDays: Rembrandt used to be a singer in a Motown band, who dumped him once they got famous. He's in the middle of staging his "big comeback" when he gets accidentally sucked into a wormhole along with the rest of the team. For the first season, he refers to himself as "[[ManlyTears The Crying Man]]," a nickname he acquired from his one hit song, though this becomes less and less as the show goes on due to CharacterDevelopment.
* GovernmentDrugEnforcement: In "Just Say Yes," in one of the PlanetOfHats worlds they visit, UsefulNotes/SigmundFreud accidentally discovered the pharmaceutical properties of lithium, which he so enjoyed that [[ForWantOfANail he became a biochemist instead of a psychologist]]. As a result, the government mandates psychotropic drug use by everyone, and the alternate Quinn is a leader of an [[LaResistance anti-drug resistance]].
* HalfHumanHybrids: The Humaggs in "The Dying Fields."
* HeroicSacrifice: [[spoiler:Arturo in "The Exodus, Part 2" (a very debatable one given the circumstances), Wade in "Requiem."]]
* HiddenDepths: Arturo, Rembrandt, Conrad Bennish Jr., Maggie.
* HollywoodNerd: Quinn
* HomemadeInventions
* TheHomewardJourney: The show's premise.
* HumansAreUgly: Or so the Kromaggs think.
* IdiotBall:
** In "The Exodus," the conflict over [[spoiler:using that world's timer to reach their home coordinates at the expense of that world]] is quite silly. At the very least, [[spoiler:Quinn could have sent everyone but himself home with a literal push of a button]], yet they keep acting like it's an all-or-none deal. Note that Quinn would end up doing exactly this in the season finale.
** Every time Quinn gets access to his double's workshop or even a full laboratory. Quinn built the original timer in his basement out of a cell phone and over-the-counter equipment, so there is no reason he couldn't build a functional duplicate given just a few days (and has had several such opportunities). This would not only allow them to choose their slide window instead of the RaceAgainstTheClock necessitated by the broke one, but in later episodes would have allowed them to slide home immediately. And to top it off, they leave their original timer (with their ''definite'' home coordinates) when it runs out.
*** Especially bad at the start of Season 2, where they meet Quinn's double who actually ''has'' created sliding technology and has quite a great deal of experience with it, but they leave almost immediately after meeting him. Worse in the fact that he actually ''did'' get them home if they hadn't decided to [[GaveUpTooSoon give up so quickly]].
** Stemming from the above, the notion that missing the slide-window renders them stuck for 29 years is ridiculous (except in Season 5, when they definitely cannot reproduce the tech). Quinn made the original timer. As long as they wound up on a world that progressed at the same relative pace as theirs, Quinn should have no trouble making a new timer and continuing on. One episode used this as a plot point to get Maggie to divulge the secret to sliding, and "Slide Like An Egyptian" has them use the Egyptian Timer once their original one fails.
* IWantYouToMeetAnOldFriendOfMine: Jason Gaffney (Bennish) is a good friend of Tracy Tormé's.
** Jerry's ''Film/StandByMe'' co-star Corey Feldman appears as Reed in "Electric Twister Acid Test." In a ShoutOut, Quinn and Reed even perform a handshake from the movie, apparently at the actors' suggestion.
* InSpiteOfANail
* InterdimensionalTravelDevice: The Timer, several of which were actually used by the main characters (the original, the one from Egyptian World and Colonel Rickman's Timer).
* JerkWithAHeartOfGold: Arturo
* KidFromTheFuture: Thomas Mallory in "Roads Taken."
* KillingForATissueSample: Colonel Rickman, who killed for brain tissue to combat a brain fungus he picked up in one of his alternate universes' wars.
* KirksRock: Featured in the episode "Electric Twister Acid Test."
* LaResistance: Whenever they're on a PlanetOfHats, there's usually a heroic LaResistance that's opposed to wearing the hat.
** This is {{Lampshaded}} in an early Season 4 episode, as characters ask and acknowledge that "there's always a resistance."
* LargeHam: Arturo, Rickman
* LeadIn
* LeftHanging: In addition to the main plot, many of the episodes use this intentionally--episodes tend to end with the group taking the next slide without the situation on the world they left being resolved. A great deal of the time the idea is that the future is uncertain...but hopefully better.
* MakingUseOfTheTwin: In real-life, Clevant's brother Clinton was used in "The King is Back," "Greatfellas" and "The Prince of Slides" to play an alternate Rembrandt.
* ManchurianAgent: [[spoiler:Rembrandt]] in "Slidecage."
* ManlyTears: Rembrandt takes pride in his ability to cry on command.
* MarsNeedsWomen: The Kromaggs.
* {{Matriarchy}}: One Universe, as a Patriarchy Flip.
* {{Misblamed}}: While there's a lot to blame producer David Peckinpah for, the trend of movie rip-offs in Season 3 isn't one of them. The real culprits were the FOX executives that he answered to.
* MisterSeahorse: Rembrandt in "The Prince of Slides."
* MotorcycleJousting: An episode features this as part of a parallel universe that seems heavily inspired by ''MadMax''.
* MouthfulOfPi
* TheMultiverse
* MythArc: Pursuing Rickman in the latter part of Season 3, and the fight against the Kromaggs in Seasons 4 and 5.
* NoodleIncident: The characters frequently mention worlds they've slid to that are never shown (for example, the world where everyone was naked, which we only saw their arrival: "So do you think that we're home?" "Ah, I don't think so, Rembrandt. I'm pretty sure on our Earth, the mailmen wear clothes.")
* NotEvenBotheringWithTheAccent: Rickman, the highest-ranking Englishman in the US army.
* NoOneCouldHaveSurvivedThat: "Summer of Love" ends with them arriving a world, only to notice the 100ft tsunami rapidly approaching San Francisco. The next (intended) episode is "The Prince of Wails," which began with the group stranded on top of a large skyscraper surrounded by flood waters and giant sharks, with little explanation how they managed to get there in time.
* NotSoDifferent: In "The Other Slide of Darkness," Quinn encounters his double from the first episode. A much more bitter and amoral person than before, Quinn's double invokes this trope.
-->"Strip your friends away, slide alone like I have--you'd be just like me. Here I am, the undeniably horrible, the unimaginably disgusting proof that I'm you without your friends."
* TheNthDoctor: Mallory replacing Quinn.
* OmnidisciplinaryScientist
* OnceAnEpisode
* OpeningNarration: The network agreed that explaining the [[MindScrew weird concept]] of {{Alternate Universe}}s to new viewers at the beginning of each show was pretty important.
* OurWormholesAreDifferent: In order to generate a wormhole, you would have to convert the entire mass of the planet Jupiter into energy. It's hard to do that with a TV remote[[note]]Egyptian timer[[/note]], a cell phone [[note]]original timer[[/note]], or a SegaGenesis controller[[note]]Rickman's Timer[[/note]].
** But it's a really ''small'' wormhole. And maybe he [[Film/BackToTheFuture stole plutonium from the Libyans]].
*** Good news! The same theorists that came up with the "mass of Jupiter" equation have also postulated how much power it would take if you used Dark Energy as the source of negative pressure. Being a much more abundant energy source, you would now require the "mere" output of several megaton nuclear warheads to get a decent-size hole in the universe going.
* OutOfOrder: The first few episodes were clearly linked, with "Summer of Love" meant to follow the premiere and then "Prince of Wails" up next. Despite the linking scenes remaining intact, the order was altered to bump up "Fever" and "Last Days." Tormé has stated that he agreed with this, however, feeling the latter episodes were better offerings. (Note that reruns tend to air in production order, making this rather moot.)
* PetsHomageName: In the first episode, Quinn mentions his cat named Schrödinger
* PickyPeopleEater: [[spoiler:Rickman]]
* PlanetOfHats: Many of the universes visited have some schtick that sets them apart from the Prime universe, either culturally or technologically.
* PlatonicLifePartners: Rembrandt with first Wade and later Maggie.
* PlotTumor
* PoliticiansKissBabies: In an episode where Professor Arturo runs for Mayor of San Francisco, he screws this up by chasing after a woman shouting "Madam, I need to kiss your baby!"
* PortalSlam
* PrecrimeArrest: During episode "Obsession", the main characters travel to a world where ten percent of the population have psychic powers. Amoung the various powers, is precognition.
** A bit of research into the history of this world reveals that psychics became popular when one warned UsefulNotes/AbrahamLincoln about his impending assassination, allowing Booth to be captured before the attempt.
** The Police Oracle identifies Arturo and Rembrandt as people who ''will'' kill Wade Wells, so the police make a Preventative Arrest. A BewilderingPunishment to all four at first. Basically, they're taken to the station, booked, and then released. If someone were to actually ''commit'' the crime, the police would have to chase them down, but otherwise the two are free to do whatever they want. [[spoiler: This is all a Batman Gambit by the old Prime Oracle to make sure his successor is a compassionate man in addition to already being a powerful one.]]
* PutOnABusToHell: According to [[WordOfGod Tracy Torme]], this was what happened to [[spoiler:Arturo, rather than being McLeaned]]. In "Post Traumatic Slide Syndrome", on a world almost exactly like Earth Prime, [[spoiler:Arturo]] and his less-ethical double have a fight as the wormhole opens and only one makes it through. Fans debated heavily over which [[spoiler:Arturo]] slid, until Torme finally confirmed in 2009 that [[spoiler:it was the alt who managed to slide out]]. This means the real [[spoiler:Arturo]] is trapped on a world not his own and separated from his friends [[spoiler:but likely still alive, unlike the alt who ended up taking a bullet for Quinn]].
** Later, Colin became "unstuck," meaning that he would involuntarily travel from one dimension to the next for the rest of his life. Dr. Geiger (a character who has experienced this before but found an "anchor") has compared this experience to being caught in a violent storm.
** Finally, [[spoiler:Logan St. Clair, Quinn's Evil HalfIdenticalTwin from another world, who was pushed into an unstable portal and never seen again.]] This is actually a DoubleSubversion, as she was intended to become a recurring villain, but like so many other story ideas, it was [[AbortedArc simply dropped]] and we never heard from her again.
* RandomTransportation: The Sliders have no control over where the Timer takes them. It gets upgraded to let them revisit worlds and track other sliders, but also gets downgraded to increase the working radius and widen the range of places they can slide to.
* RecurringExtra: Alternates of various folks would sometimes crop on different worlds.
* RecycledInSpace: One of the most persistent complaints of Season 3. The vast majority of the episodes ripped off a number of movies, including ''Film/{{Tremors}}'', ''Film/{{Twister}}'', ''Franchise/ANightmareOnElmStreet'', ''Film/{{Species}}'', ''Film/{{Anaconda}}'' and ''Film/TheIslandOfDoctorMoreau''.
* RecycledSet:
** A common complaint of later seasons, as diminishing budgets meant heavily re-using the standing sets (such as the Chandler Hotel).
** "Slidecage" re-uses the futuristic standing sets from the short-lived ''{{Timecop}}'' TV series, which had been cancelled shortly into Season 4's filming. Writer Marc Scott Zicree has stated he wrote the episode to make use of the great sets that were going to be torn down.
* RetroUniverse
* RubberForeheadAliens: [[JustifiedTrope Justified]] this time, as the Kromaggs are supposed to share recent common ancestors with [[HumanAliens normal human beings]].
** Don't forget the Humaggs in Season Four's "The Dying Fields."
* ScrewTheRulesIHaveSupernaturalPowers: This is pretty much the Sliders' philosophy when it comes to running afoul of a bizarre rule or circumstance they had no way of knowing about. After all, it's hard for police or debt collectors to pursue you when you can jump from one Earth to another.
** Episodes featuring worlds where some of the inhabitants have supernatural powers will invariably have at least one person who thinks this way.
* ShoutOut: In "Gillian of the Spirits," Quinn [[spoiler:is stuck in an astral plane, making him invisible and intangible. In one scene, he is talking to the only person who can see him (the titular Gillian) in the back of a taxi, and]] the driver, confused, asks twice "Are you talkin' to me?" then, after Quinn gets out, he says [[TaxiDriver "There's no one else here, so you must be talkin' to me!"]]
* SingleEpisodeHandicap
* SkywardScream
* SlowMotionDrop
* TheSmartGuy: Arturo. Quinn has his moments as well. Not surprising, considering the former is a lecturer in advanced physics and the latter is his grad student.
* SmartPeopleKnowLatin: In one Season 1 episode, the protagonists end up in a world where being smart and well-educated is cool (they pass a punk on the street with a boombox blasting classical music). The episode's BigBad is a mobster who constantly likes to quote phrases in Latin and gets annoyed when the others have no idea what he said. At the end of the episode, right before sliding, Quinn turns around and spouts a phrase in Latin, which turns out to be an insult.
* SorryILeftTheBGMOn
* SoWhatDoWeDoNow: [[spoiler:The last line of the series.]]
* SpiritualSuccessor: ''Sliders'' is this to ''QuantumLeap''. The shows share a similar episode formula, ''Sliders'' was advertised at least once as "''Quantum Leap'' with an edge," and dialogue in a later episode implies that Maggie Beckett may be Sam Beckett's niece.
* SpotTheImpostor
* SpringtimeForHitler: In "The Weaker Sex," Arturo tries to throw an election by weeping in front of the camera, but it backfires and his approval ratings go up.
* StargateCity: Seasons 1 and 2 are filmed in Vancouver. Standing in for UsefulNotes/SanFrancisco.
* TeenGenius: Quinn
* ThisIsReality: During "To Catch a Slider," as Rembrandt points out the dangers of robbing a jewelry store.
-->'''Rembrandt:''' This is not a movie. As strange as it is, this is our lives.
* ThisWasHisTrueForm
* TimTaylorTechnology: "MORE POWER, MR. MALLORY!"
* TimeParadox: In one universe, time flows backwards. The Sliders still go forwards in time, however, and Quinn ends up stopping something that put him in jail, after he started out there. The result is...[[NightmareFuel not pretty.]]
* UnlimitedWardrobe
* TheUnreveal: At the end of "Post Traumatic Slide Syndrome," it's never made clear ''which'' Arturo actually slid with them.
** [[spoiler:[[WordOfGod Tracy Tormé]] finally revealed in 2009 that it was the ''wrong'' Arturo.]]
* UnpredictableResults: Their own "sliding" device, about the only thing consistent is that it drops them in a location somewhere close to the entrance point between the two dimensions they travel between. Later seasons gave them the ability to at least control when they are going to travel and which dimension they are going to. But since they don't know their home destination, they still have to travel to different dimensions sequentially to find it.
* UnsettlingGenderReveal: Happens in [[spoiler:"To Catch a Slider," where Mallory expresses interest in an actress who turns out to be a man. It's somewhat subverted in that this was public knowledge. It's just that none of the Sliders could've possibly known because they had just recently arrived.]]
* {{Utopia}}
* ViewersAreMorons: Suffice to say, with all the ExecutiveMeddling this show suffered, this trope cropped up. In "Slither," for example, snakes somehow knock down a door. This was so idiotic that Cleavant Derricks said he interrupted a script reading to ask how such an action was even remotely possible and a producer responded that the snakes possessed some kind of force, much to Derricks' irritation.
* WalkingTheEarth: Plural, in this case.
* WastelandElder: They ran into quite a few, and every so often an alternate of the main cast would be a local leader.
* WeHaveForgottenThePhlebotinum
* WhamEpisode: "Genesis." The Kromaggs have conquered Earth Prime, Rembrandt has been their prisoner for months, Wade is missing, Quinn learns of his secret past (including a [[LongLostRelative long lost brother]]) and the Sliders have a new goal of searching for an anti-Kromagg weapon.
* WhamLine:
** From "Invasion":
-->'''Quinn:''' Wade, the Kromaggs - they're Sliders!
** "Double Cross":
--->'''Logan:''' ''(to Quinn)'' [[spoiler:You're ''my'' double]].
* WhatHappenedToTheMouse : They slid with a dog in a first-season episode, and no mention what happened to it.
* WhatIf
* WhiteDwarfStarlet: Rembrandt
* WholePlotReference: "The Good, the Bad and the Wealthy" is a mix of ''{{Shane}}'' and ''TheManWhoShotLibertyValance''.
** "Into the Mystic" owes a lot to ''TheWizardOfOz'', which is referenced during the episode.
** Season 3 was rife with these: "The Dream Masters" (''Franchise/ANightmareOnElmStreet''), "The Fire Within" (''Film/{{Backdraft}}'' with sentient fire), "The Prince of Slides" (''Film/{{Junior}}''), "Paradise Lost" (''Film/{{Tremors}}''), "The Breeder" (''Film/{{Species}}''), "The Last of Eden" (the Morlocks aspect of ''TheTimeMachine''), "The Other Slide of Darkness" (''Film/ApocalypseNow''), "Slither" (''Film/{{Anaconda}}'') and "This Slide of Paradise" (''TheIslandOfDoctorMoreau'').
* YankTheDogsChain: In "Into the Mystic," the Sliders have a chance to go home, think they failed and leave[[spoiler:--only for viewers to then see they actually were home]]. "Post Traumatic Slide Syndrome" also involves a great deal of this trope, with the Sliders landing on a near-perfect copy of Earth Prime.
* YouCantGoHomeAgain: Subverted when [[spoiler:they actually make it back to their home Earth, but only have a few seconds to decide to stay or not. They leave after Quinn tries a fence, knowing it is always squeaky, and it doesn't squeak. After they leave, you see a gardener with an oil can]].
** They make it home again in "Genesis," but with the world conquered by the Kromaggs, they leave to find a weapon to defeat them.
* YourMindMakesItReal: "The Dream Masters." Said group is able to enter other people's dreams and twist them into whatever horrifying nightmares they can think of. After Wade falls victim to them, the other Sliders manage to find a way to enter the dream and pull similar tricks to their advantage. After all, it's just a dream.
-->'''Rembrandt:''' I wish I had my gun right now. ''(shotgun suddenly appears in his hand)''
