->''"I stand for truth, justice, and... other stuff."''

A series, airing on Creator/TheWB and later Creator/TheCW (from 2001 to 2011), that chronicles Clark Kent's adolescence as he comes into his powers and eventually takes on the mantle of Franchise/{{Superman}}.

The show started out as more of a TeenDrama, focusing largely on Clark's interactions with his friends, family, and LoveInterests, and how this leads to his [[CharacterDevelopment development]] as a SuperHero. It initially took a MonsterOfTheWeek approach to most episodes, introducing "[[AliensAndMonsters meteor freaks]]" who gain various [[WithGreatPowerComesGreatInsanity powers]] thanks to exposure to [[GreenRocks Kryptonite]] deposited in Smallville during the meteor shower which heralded Clark's arrival. As the years went by, a more diverse array of adversaries were gradually introduced, and the TeenDrama elements fell away in favor of a somewhat darker tone, and a much deeper connection to DC Comics lore.

Whereas ''Series/LoisAndClark'' shifted gears toward a Comicbook/PostCrisis vision of Superman, Creator/JephLoeb led the way in bringing many [[UsefulNotes/TheSilverAgeOfComicBooks Silver Age]] ideas back into prominence on ''Smallville''. Most notable among these is the origin tale of Clark and ComicBook/LexLuthor knowing each other in high school, and Comicbook/LoisLane being introduced to Clark long before their partnership at the ''Daily Planet''.[[note]]Interestingly enough, one 1940's comic featured a young Clark/Superboy winning a high school journalism contest, with the prize being a day as a cub reporter on the ''Daily Planet''. Guess who the other winner was?[[/note]]

The first half of the show (Seasons 1-5) dealt strictly with Clark figuring out who he was, while the second half was more about Clark finding his place in the larger [[Franchise/TheDCU DC Universe]], frequently butting heads with recurring guests such as Comicbook/GreenArrow, the rest of the Junior Lifeguard Associ-- er...Franchise/JusticeLeagueOfAmerica, the Comicbook/{{Justice Society|OfAmerica}}, the ComicBook/LegionOfSuperHeroes, and even the Comicbook/NewGods.

The show managed to survive for a decade, arguably[[note]]''Series/StargateSG1'', while three episodes shorter, has two additional MadeForTVMovies and is undeniably straight sci-fi, while ''Smallville'' has explicit magic in the form of Zatanna[[/note]] beating ''Series/StargateSG1'''s record as the longest running American SciFi show (''Franchise/PowerRangers'' doesn't count, because it uses Japanese-made footage). The show concluded its tenth and [[FinaleSeason final season]] in May 2011, and given that Smallville (the town) had barely appeared since Season 8, the show could have quite reasonably been renamed ''Metropolis'' for the final stretch.

A "Season 11" has been made in comic book form, featuring the adventures of Clark in the ''Smallville'' universe, now as Tom Welling's likeness in a new Superman costume. It's [[ArtifactTitle still called "Smallville" though]], to signify that it's a continuation of the series.

!!This Series Provides Examples Of:


[[folder: A to B]]
* AbsurdlyPowerfulStudentCouncil: Chloe seems to believe that Smallville High has one. When Clark decides to run for StudentCouncilPresident, she grills him on his positions on issues ranging from the menu prices in the cafeteria to the administration's habit of searching student lockers for drugs, in a manner that suggests she thinks he'll have some influence over those policies.
%%* AccidentalAthlete: "[[Recap/SmallvilleS01E03Hothead Hothead]]"
%%* AccidentalHero: "[[Recap/SmallvilleS07E13Hero Hero]]"
* AdaptationDyeJob: Lana Lang was a [[HeroesWantRedheads redhead]] in the comics, and Lois Lane had [[BrainyBrunette jet-black hair]]. In this version, Lana is a brunette and Lois starts out with light-brown hair.
* AdaptationPersonalityChange: Like ''Film/ManOfSteel'' would do later, Zod is given a new personality and motivation for his actions. Depicted as more of a strategic planner due to being de-powered for the most part, he actually seeks out to befriend Clark, believing he can help their people gain their powers like him, and actually strikes up a friendship with Lois (mostly to manipulate her). His motivation is also changed; instead of wishing to rule ForTheEvulz, he was originally a noble, charismatic military leader [[WoobieDestroyerOfWorlds whose family died in the battle of Kandor, and was denied the chance to clone his beloved son, resulting in his]] StartOfDarkness. He's a literal WoobieDestroyerOfWorlds in this case too, as he's responsible for the destruction of Krypton in this continuity.
* AdaptationalEarlyAppearance: A lot of characters (specifically ComicBook/LexLuthor, ComicBook/LoisLane and various superheroes and supervillains) in the show showed up years '''before''' Clark Kent even became Franchise/{{Superman}}.
* AdaptationalVillainy: Zor-El was a good guy in the comics, but a villainous would-be conqueror in the series.
* AIIsACrapshoot: Brainiac (it's implied that Zod corrupted his programming).
* AlasPoorVillain: Lex in Season 8 attracts this reaction in-universe.
* AlreadyMetEveryone: Almost everyone ''except'' Franchise/{{Batman}} and Franchise/WonderWoman.
%%* AlternateUniverse: "[[FilmNoir Noir]]," "[[ItsAWonderfulPlot Apocalypse]]," "[[ForWantOfANail Luthor]]."
* AmnesiacLiar: When Chloe tells Clark he's a meteor freak in "Blank," though she didn't know that she was lying since she really did think he was meteor-infected.
** CriminalAmnesiac: [[spoiler:Lex, on the other hand, immediately exploits the situation to learn something important about the Kawatche Caves]].
%%* AmnesiaDanger: "[[Recap/SmallvilleS04E19Blank Blank]]"
* AndThenWhat: One could deconstruct Zod's motivation as failing to take this into account, since he doesn't appear to have ''any'' long-term goal other than to take over Earth to turn it into a New Krypton. In fact, the BadFuture seen in "Pandora" shows that the Kandorians don't seem to be doing more than spinning their wheels, rounding up humans in slave camps, all while letting the planet fall into a state of disrepair. Behold the ''[[SarcasmMode glorious]]'' New Krypton, folks?!
* ApocalypseAnarchy: Riots break out all over the world when Brainiac unleashes a computer virus which starts shutting down all technology on Earth during the episodes "Vessel" and "Zod."
* ApologisesALot: Clark and Lana.
* ArbitrarySkepticism: All over the place.
** A good example is "Legion," where despite having spent the last eight years dealing with meteor-infected humans, naturally occurring superheroes, and aliens visitors from other worlds...apparently {{time travel}} is considered to be ''too'' ridiculous?!
*** Clark himself had actually time traveled at least twice ("Reckoning" and "Apocalypse") before "Legion".
** Jonathan and Martha, the foster parents of a [[HumanAliens human-looking alien]] with physics-defying superpowers, balk at the idea that magic exists.
** Glaringly subverted in "Spirit" where a case of BodySurf is {{handwave}}d by Chloe saying "We ''are'' in Smallville."
* ArtifactAlias: Oliver Queen continues using his ComicBook/GreenArrow alias and costume, right down to the voice-changer that gives him a BadassBaritone, even after revealing his identity on national TV at the end of the "[[Recap/SmallvilleS10E03Supergirl Supergirl]]" episode.
* ArtifactTitle: By Season 8, Clark had left Smallville to join the ''Daily Planet'' in Metropolis (as he obviously had to, sooner or later), though an argument could be made that "Smallville" is now more a reference to Clark himself, via Lois' nickname for him. Also, Clark doesn't think of himself as Franchise/{{Superman}} at this point; Seasons 8-10 are about him letting go of his Smallville life to become the man he needs to be. "Smallville" was how he hid in the shadows; "Superman" is when he steps into the light.
* ArtisticLicenseLaw: In "Nemesis" Lana threatened Lionel with the fact that she has power of attorney and is in charge of making his medical decisions. The problem is that not only is Lionel recovering but he is conscious so not only can’t Lana do anything besides create mild inconveniences but he can revoke the power of attorney.
* ArtisticLicenseMedicine: In "Action" Lionel was stuck in a trap for at least a day that should for all intents and purposes had caused him to lose his hand due to how long he was trapped and how sharp the trap was.
* AsideGlance: Halfway into the tenth and final season, Clark returns from the dystopian Earth-2, but not without someone tagging along for the ride: [[spoiler:Earth-2's Lionel]], still alive and well, takes in the sights while a newspaper man tries to fix him in his memory. [[spoiler:Creator/JohnGlover]] buys a paper, looks straight in the camera, and basically says he's pumped for the series finale.
* AwesomeMomentOfCrowning: Clark ''finally'' putting on the iconic Superman suit in "[[ExactlyWhatItSaysOnTheTin Finale]]."
* AxesAtSchool: The {{Trope Namer|s}}, from the Season 3 episode "Delete." In Season 4's "Spirit," the trope comes up again.
* BabyDollBaby: In the episode "Memoria," Lex is sitting on a high balcony, in the rain, apparently hallucinating that he is rocking his baby brother Julian to sleep. He's singing to the blanket and tells his father to be quiet or he'll wake the baby. He thinks he found the baby inside of his dorm, crying, and told Julian that he'd never let anyone hurt him again.
* BackForTheFinale:
** [[spoiler:Creator/MichaelRosenbaum as...[[ComicBook/LexLuthor take a wild guess]].]]
** [[spoiler:Chloe Sullivan, who left in "Fortune".]]
** [[spoiler:Lionel (Creator/JohnGlover) also came back ([[AlternateUniverse sort of]]) for the final season, and Zod returned for the episode "Dominion."]]
** Aaron Ashmore reappeared as Jimmy Olsen...the ''real'' Jimmy Olsen. [[spoiler:Also, Jonathan Kent reappears multiple times in the finale, most notably appearing as a ghost to hand Clark his iconic suit in the Fortress of Solitude.]]
* BadassArmy: [[spoiler:Zod and the Kandorians in Season 9]].
* BadassBoast: Amusingly, we get one from ''the surgeon'' [[spoiler:about to undo life-threatening AND crippling shots to Lex Luthor]] on Christmas Eve no less, in "Lexmas".
--> "Somebody kill the carols. I'm about to perform a miracle."[[note]]And StatusQuoIsGod ''demands'' that he pull it off![[/note]]
* BadassFamily:
** The Kents/The Els. You've got [[Franchise/{{Superman}} Clark]] himself, [[BadassNormal Jonathan]], [[ComicBook/{{Supergirl}} Kara]], Jor-El (who MinoredInAssKicking), and his [[CainAndAbel evil]] brother and MadScientist Zor-El. In Season 9, [[spoiler:Martha became TheChessmaster]], making the family complete.
** The Luthors are a villainous example. Between Lionel, [[BadassLongcoat Lex]], and [[spoiler:[[DarkActionGirl Tess]]]], they definitely count.
** There is also [[spoiler:[[ComicBook/{{Superboy}} Conner Kent]], who is the clone of Lex and Clark.]]
* BadassLongcoat: Clark's costume in Season 9; Lionel and Lex all the time.
%%* BadFuture: "[[Recap/SmallvilleS07E18Apocalypse Apocalypse]]", "[[Recap/SmallvilleS09E09Pandora Pandora]]"
* BadGuysDoTheDirtyWork:
** The end of "[[Recap/SmallvilleS02E01Vortex Vortex]]." [[spoiler:Nixon threatens to expose Clark to the world and there's nothing Jonathan can do about it...until Lex shoots Nixon dead.]]
** "[[Recap/SmallvilleS09E17Checkmate Checkmate]]" Both the Justice League and Zod have a bone to pick with [[GovernmentConspiracy Checkmate]]. [[spoiler:Oliver and John get captured at different points, although they managed to escape. Chloe is also kidnapped and almost killed in an attempt to blackmail Clark into revealing more about their team.]] Zod simply comes over to visit and burns down their entire castle base with [[EyeBeams heat vision]].
* BatmanGambit: Clark and Oliver pull one off in [[spoiler:"Dominion." They knew Zod wouldn't be able to resist killing Clark himself.]]
%%* BattleInTheRain: [[spoiler:Clark vs. Zod]] in "[[Recap/SmallvilleS09E22Salvation Salvation]]."
* BecauseDestinySaysSo: Jor-El's favorite trope, apparently. We already know the ending; this show's about the journey.
* BehindTheBlack: Apparently [[GreenRocks Kryptonite]] only affects Clark when he can see it.
* BeneficialDisease: In "Ryan," the titular character has a brain tumor that gives him telepathy. It's revealed to be fatal, however, and they are unable to reach an expert who could possibly save him before it's too late.
* BetrayalInsurance: Chloe has (or had) caches of Kryptonite stashed around the world. It is not clearly stated if it is for [[spoiler:the Kandorians]] or Clark, but Clark is understandably upset when he finds out.
* BigBad:
** Lionel; later [[spoiler:Brainiac, Lex, Davis/Doomsday, a younger clone of Zod with an army of Kryptonian clones at his command, and Comicbook/{{Darkseid}}]].
** The [[spoiler:parallel-universe Lionel Luthor will seem to be even more evil and dangerous than his counterpart in the "original" universe was before he was changed by Jor-El]].
** And while it was brief, Michael Rosenbaum showed up in the finale [[spoiler:as Lex Luthor]].
* BigBadEnsemble: After Lionel started turning around, most seasons would feature at least two antagonists who would frequently get in one another's way.
** Season 4 had [[EvilMatriarch Genevieve Teague]] and [[WickedWitch Isobel]].
** Season 7 had [[ManipulativeBastard Lex]] and [[RoboticPsychopath Brainiac]].
** Season 8 had [[CorruptCorporateExecutive Tess]] and [[PersonOfMassDestruction Doomsday]] (with Faora as TheManBehindTheMan).
** Season 9 had Zod and [[GovernmentConspiracy Checkmate]].
** Season 10 is really complicated with Comicbook/{{Darkseid}}, Rick Flag, Alexander, Earth-2 Lionel, and [[spoiler:the real Lex]] all competing for the title.
* BlackBestFriend: Pete Ross, Seasons 1 to 3.
* BlackDudeDiesFirst: The first person to die of chronic kryptonite exposure was a black guy. So was the second, for that matter.
* BlingOfWar: In "Rogue," Lex shows Clark a breastplate that once belonged to Alexander the Great. In addition to [[MythologyGag looking strikingly like Superman's costume]], it's made out of gold and crusted all over with sapphires and rubies.
* BlondeBrunetteRedhead: Chloe, Lois, and Tess, respectively. Also, the Kent family, with Jonathan, Clark, and Martha.
* BloodSplatteredWeddingDress: [[spoiler:Chloe in "Bride" and "Legion."]]
* BodySurf: The Phantoms, Zod, numerous meteor freaks, the witches in "Spell," Darkseid.
* BookEnds:
** An almost perfect example--in the pilot episode, Lex rescues Clark from a prank of being strung up on a scarecrow post in the middle of a field. In the first episode of the last season, the Old Lex clone ties Lois up on the same post as bait for his and Clark's TheLastDance. The clone actually [[LampshadeHanging comments]] on this to both of them.
** Also both the Season 1 premiere and finale feature a school dance and a natural disaster (though how natural the meteor shower was depends on how you look at it).
** The GrandFinale. [[spoiler:It starts with Chloe reading a ''Smallville'' comic book to her son, and not counting the obligatory final scene of Superman going off the save the world, it ended with her finishing the story and tucking him into bed.]]
* BoundAndGagged: Lana, most of the time. Though Clark had a few notable examples. [[spoiler:Chloe in "Checkmate."]]
%%* {{Brainwashed}}: "[[Recap/SmallvilleS03E07Magnetic Magnetic]]," "[[Recap/SmallvilleS03E11Delete Delete]]," "[[AppliedPhlebotinum Odyssey]]," "[[Recap/SmallvilleS09E14Persuasion Persuasion]]."
* BoysLikeCreepyCritters: In the first episode after the pilot, the MonsterOfTheWeek boy who was into bugs. His mother didn't know what he could do with such a hobby; apparently she's never heard of entomology.
* BrainwashedAndCrazy: "[[Recap/SmallvilleS05E16Hypnotic Hypnotic]]". If it's not Clark cheating on Lana, it's Martha Kent wielding a shotgun and acting like she's confiscating a child's video games.
* BrainwashedAndCrazy: Inverted. Brainiac 5 is quite sane and nice after he is reprogrammed.
* BreakingTheFourthWall: Season 10's "[[spoiler:Luthor]]" gives us this:
-->''"I'm from [[AlternateUniverse out of town]]. Unexpected visit. But I guess I'm back in the nick of time. Wouldn't want to miss how it all turns out."''
* BrickJoke:
** In "Fragile", Clark hopes to relate to the young budding artist [[spoiler:and meteor freak of the week]] Maddie through her art - but he's a HorribleArtist. At the end of the episode, it's revealed that Maddie took Clark's drawing and did her best to improve on it.
* BrokenAesop:
** At the end of "Unsafe," Martha lectures Clark on using better judgment about something he did ''while he was on red kryptonite'', which impairs his judgment. Characters in the show are pretty consistently forgiven for things they did while they weren't themselves, including at the beginning of Season 3 when Clark comes home after a much longer bout with red kryptonite in Metropolis ''during which he was committing serious crimes''. And for all of that he was on red Kryptonite voluntarily, whereas in "Unsafe," Alicia gives it to him without his knowledge.
** The moral of "Bound" seems to be that if you use women like a paper towel, it will come back to haunt you, even if you're rich. Problem is, it's not what plays out in the show; the woman were shown to be perfectly willing parties, with the victim being the one who initiated the relationship. The episode seems to completely ignore that given Lex’s past relationships with woman it is perfectly understandable why he would opt for meaningless flings, but the only two women who had a problem with this the murderer and her victim both proved to be completely insane. The victim coming across as a stalker and the murderer trying to invoke NeverMyFault.
* BroughtDownToNormal: Used often; never sticks. To be fair, at least once with Clark, it stuck for two episodes (longer than it's ever stuck in a Superman series outside of the comics). And with [[spoiler:Comicbook/MartianManhunter]], it stuck till Comicbook/DoctorFate restored his abilities.
* BulletTime: The "Clark time" when Clark goes into SuperSpeed mode.
* BullyingADragon: In the episode "[[Recap/SmallvilleS01E09Rogue Rogue]]", a DirtyCop who sees Clark using his powers uses that knowledge to blackmail him. Sure, Clark's ThouShaltNotKill philosophy prevents him from easily killing the guy with said powers, but he doesn't know that. All he knows is that Clark is tough enough to stop an out-of-control bus by stepping in front of it and strong enough to toss a generator across a room like a wad of paper. And yet, he keeps on provoking him and even threatening his family. [[spoiler:KarmicDeath took care of him.]]
* BuffySpeak: "Bug bites boy, and boy becomes bug boy!"
* TheBusCameBack: Pete Ross returned for one episode in Season 7, and Lana returned partway through Season 8 for a small story arc. [[spoiler:Kara]] in Season 8's "Bloodline" and Season 10's "Supergirl." Season 10 had practically ''every'' major character who had departed the show [[ContinuityPorn return in some capacity]] during the season. Notably, Pete and Lana were the only living characters not to return during the season, whilst any other characters who didn't come back had been KilledOffForReal. [[spoiler:Not that being dead managed to stop Jonathan, Lionel, and Lex returning in some capacity.]]
* BusmansHoliday: Clark, Lois, Oliver, and Chloe all choose the Bed & Breakfast [[AllMythsAreTrue with the legend about a woman who felt so betrayed that she made a deal with the underworld and was allowed to walk among the living again to kill any man who crosses her path]].
* ButNowIMustGo:
** "Justice" (in an awesome closing scene), "Requiem."
** Episodes that introduce a SuperHero from Franchise/TheDCU end with this--"Run", "Aqua," and "Cyborg."
** And in Season 10, [[spoiler:Chloe in "Fortune."]]

[[folder: C to D]]
* CainAndAbel: In Season 7, Lex ends up creating his own CainAndAbel, [[spoiler:when it's revealed he made Grant Gabriel as a clone of his dead baby brother. When Grant discovers this, he becomes very angry and hateful of Lex. Grant tries to form a familial relationship with their father Lionel against Lex's wishes. So Lex hires a hitman to gun him down.]] Then Lex [[{{Narm}} goes outside to scream in the rain]].
** ''Smallville'' also has Zor-El, Kara's father, who is antagonistic towards his brother Jor-El because of his love for Jor-El's wife Lara.
** Lex and Clark have been billed as being in a Cain-and-Abel relationship since the very first episode, it seems. On Earth-2, Clark was adopted by Lionel Luthor and it didn't end well for Lex. And Lionel is OK with that because he believes in social Darwinism. However, Lionel was furious that his adoptive son hadn't killed him yet, as should be expected. After coming to "our" universe, he soon began to miss his son and planned to revive "our" Lex. [[spoiler:Which he did.]]
** Jor-El and Zod were also similar to Clark and Lex.
** Lex ultimately ends up the Cain to yet another sibling: [[spoiler:younger half-sister [[WellIntentionedExtremist Tess]] [[BrokenAce Mercer]], who he murders in the GrandFinale. His reasoning is that it's a version of a MercyKill so that she doesn't end up [[CardCarryingVillain like]] [[TheSociopath him]], but few people buy that; he almost definitely killed her so that she was out of his way, since at the time she had control of [=LuthorCorp=]]].
* CaliforniaDoubling: Vancouver variant.
* CallBack: "Asylum" has several past villains reappear when the action enters Belle Reve.
* CallForward: As mentioned elsewhere, this happens constantly and in spades. Though it comes up rather [[{{Prequel}} naturally]]. Properly the most notable one is Clark becoming Superman, Lois and Clark hooking up, and Lex becoming the villain. However, there were twists that did come out of nowhere, [[spoiler:such as [[ComicBook/{{Superboy}} Connor Kent]] in ''Season 10'' and Jonathan Kent dying in ''Season 5'']] but do occur if you have seen the right clue.
* CanonCharacterAllAlong: ZigZaggingTrope with Chloe Sullivan who, when she writes her first piece for the ''Daily Planet'', uses her cousin's Lois Lane's name as her ''nom de plume'' - setting up that Chloe is the ''Smallville''-verse Lois. But later in the series Lois proper shows up. Chloe does become that universe's analogue of Oracle.
* CanonImmigrant:
** At Comic Con 2010, [[http://www.digitalspy.co.uk/comics/news/a250561/chloe-sullivan-comes-to-comics.html it was announced]] that Chloe Sullivan had become part of the [[Franchise/{{Superman}} official DC Superman comics]].
** Played straight with Lionel Luthor, who is now canonically Lex's father. Lionel, and Creator/JohnGlover's portrayal of him, resonated so well that he was written into the comics as Lex's canonical (and deceased) father. While Lex had obviously always had a (deceased by the time of the "present day") father, this character had never had a consistent name or physical appearance and usually had no importance. But ever since ''Smallville'', Lex's father is explicitly named "Lionel Luthor" and flashback scenes have depicted him as looking very similar to actor Creator/JohnGlover. A zombiefied, Black Lantern version of Lionel even showed up for revenge against Lex in Comicbook/BlackestNight.
** Besides characters, various elements from ''Smallville'' that have made their way into the comics include the ''Smallville'' version of Comicbook/GreenArrow's costume which--as of the Comicbook/{{New 52}}--is now Ollie's official costume. Also, Oliver's clean-shaven appearance from ''Smallville'' has made its way into the comics as of the Comicbook/{{New 52}} (these last two changes can be attributed to the fact that ''Smallville'''s version of Ollie is probably the best-known version to the general public). Also the idea of ComicBook/LexLuthor spending time in Smallville during Clark's teenage years--though originally an idea from the Silver Age ''Superboy'' comic books that was retconned away at the start of the Post-Crisis era--was brought back into continuity largely thanks to ''Smallville''. And more, Ma and Pa Kent in the comics have started to look like older versions of Annette O'Toole and John Schneider, even though it often [[DependingOnTheArtist depends on the artist]].
** As of Creator/GeoffJohns's SupermanSecretOrigins miniseries, ''Smallville'''s idea of a young Clark learning how to use his powers while secretly defending the citizens of Smallville from meteor freaks is now officially part of Superman's backstory in the comics.
* CaptainObvious: Chloe, sometimes.
* CassandraTruth:
** Several people who know Clark's secret have been committed to a mental hospital, and so their claims aren't believed. Pete also once tried to expose Clark but predictably failed.
** Lex's story of being possessed by an alien warlord is also ridiculed.
* CataclysmClimax:
** "Tempest": [[spoiler:a tornado hits Smallville]].
** "Commencement": [[spoiler:Another meteor shower hits the town]].
** "Vessel": [[spoiler:Brainiac unleashes a computer virus that causes all technology on Earth to shut down, causing mass hysteria]].
* CharacterDevelopment:
** Clark and Lex start as friends, but fall apart as Clark grows into a superhero and Lex into a supervillain.
** Likewise, Clark and Lois, who initially found each other's company difficult, grow closer as they both discover their journalistic callings and shared passion for justice.
** Lana changes from DamselInDistress to ActionGirl in the very later seasons. Of course, it's not always consistent.
** Chloe is an outstanding example of CharacterDevelopment. In the early seasons, she was rash, impulsive, and always eager to expose the truth about everything. When she got [[ClingyJealousGirl extremely jealous of Clark and Lana's relationship]], she [[spoiler:made an ill-advised deal with Lionel to spy on him as {{revenge}}, though she quickly regretted it]]. A year-long BreakTheCutie StoryArc and a ton of character growth in Season 3 made Chloe become more mature as time went on. Season 4 opened with Chloe and her father living in hiding as part of the fallout of her actions a year earlier. Eventually, they were able to come out of hiding. By the time Chloe learned Clark's secret in mid-Season 4, she had matured to the point where she told no one, not even telling Clark himself that she knew, choosing to allow him to tell her when he was ready. In Season 5, once Clark knew she had discovered his secret, she became a valuable sidekick and helped him save the day on many occasions.
** Lionel, too. At the beginning of the series, he was TheChessMaster and Season 3 featured him as the show's true villain, while Lex during these seasons was a somewhat dark but generally good man. By the time both Luthors exited the show in Season 7, Lex had transitioned all the way to TheDarkSide, while Lionel had been redeemed by Clark.
** Cat Grant (the one introduced in Season 10, not Season 9) went through this as well, as she comes to appreciate The Blur in "Booster."
* CharacterShilling: LANA! It began all the way back in Season 1, when everybody in the town kept gushing about how amazing and strong and wonderful Lana was...despite the fact that [[ShowDontTell there was very little on screen to actually confirm this]], and most fans found her to be kind of underwhelming. So the writers decided to emphasize Lana's talents to an unrealistic extent, having her start up a coffee shop at the age of 15, while apparently engaging in equestrian competitions and maintaining a high grade point average; fans found this unrealistic and quickly noticed the character shilling, and began to be annoyed. Then the writers apparently decided that the best way to address this was to...shill her ''even more''. All the fan favorite characters--including Chloe and Lex--began gushing about how amazing Lana supposedly was. It still didn't work. So the writers began shoving her into every storyline they could think of, but all it did was make fans despise her even more. The pattern kept on going and became a vicious cycle: fans would dislike Lana, and the writers would attempt to change this by ramming her down the audience's throats even more, which in turn just made people dislike Lana to an even greater extent. It got to the point where Lana's send-off involved her [[spoiler:essentially becoming a GodModeSue]]. Naturally, many fans threw up their hands in disgust at this development, but at least she left the show (finally).
* ChekhovsGun: Plenty throughout the series run; for example in "Icarus," Lois escapes from Slade's soldiers in the ''Daily Planet'' building by using the escape tube in Tess' office, which was established as existing a season earlier.
* CheshireCatGrin: Tess is REALLY good at doing this. Whenever she's plotting something, or something she plotted has come through, she'll pull one of these. Subverted, as what she's planning usually isn't exactly evil; it's just morally ambiguous.
* ChessMotifs: Checkmate, an agency introduced in Season 9 that attempts to weaponize superpowered beings, uses chess terms and puns. Their leaders are codenamed "White Queen" and "Black King," {{Mooks}} are called pawns, etc. Their base even has black and white squares all over the place.
* ChildhoodFriendRomance: Chloe seems to be the unlucky childhood friend, especially since we all know that Clark marries her cousin.
* ChristmasEpisode: "[[Recap/SmallvilleS05E09Lexmas Lexmas]]" centered on Lex's "prefect" dream in which he is married with Lana, with a young boy and expecting a girl, and Clark is with Chloe. He gives up the senator race but wins the Humanitarian award of the year, and is on excellent terms with everyone except Lionel, but who cares? [[spoiler:[[TearJerker/{{Smallville}} At least, not until the dreaded]] DreamApocalypse...]]
* TheCityNarrows: Called [[NamesToRunAwayFromReallyFast Suicide Slums]] here.
* ClarkKenting: Not so much Clark himself, but Oliver Queen. He dresses up like Myth/RobinHood for a party in "Wither," then in the ''next'' episode, the Green Arrow (Oliver in disguise) steals a necklace at a party. Lois, of course, [[LovesMyAlterEgo doesn't see a connection]].
%%* ClearTheirName: "Suspect," "Infamous," "[[Recap/SmallvilleS04E09Bound Bound]]."
* {{Cliffhanger}}: Every season finale up until the series finale ends with one. Usually with major characters in mortal peril.
* CloningBlues:
** The Lara and Zor-El clones in Season 7's "Blue."
** [[spoiler:Zod and the Kandorian soldiers in Season 9]], [[spoiler:Jor-El in "Kandor."]]
** The [[spoiler:Lana clone]] created just to be killed, so [[spoiler:she could [[FakingTheDead fake her death]]]]. Lex would [[spoiler:do practically the same exact thing]] to [[spoiler:[[FakingTheDead fake his death]]]].
** Grant Gabriel and Adrian Cross, aka [[spoiler:Julian Luthor]]. Season 7 in general could have reasonably been given the tagline "Attack of the Clones," given that this season features all the clones mentioned above (except for [[spoiler:the Zod clone from Season 9 and his army, of course]]), plus Bizarro for three episodes.
** Season 10's "Lazarus" features more clones intended for organ transplants for Lex. One was in a tank, another was a child, and a third, more aged clone, oddly similar to [[Literature/HarryPotter Voldemort]]. The child clone survived and [[spoiler:turned very, very [[EnfantTerrible evil]]...except after going through the CloningBlues, the clone was revealed to be Conner Kent/Superboy (who had gone through his own share of CloningBlues).]]
* ColonyDrop: [[spoiler:Apokolips comes within a few miles of impacting Earth before Clark, as Superman, pushes it away.]]
* ColorMotif: Early episodes also liked to use primary colors for anything related to Clark Kent, hinting at his future as Superman. It was also done for environments. The town of Smallville--and the Kent Farm, in particular--were given very warm tones, while Metropolis was portrayed for many seasons through a bluish filter to give the sense that pre-Superman Metropolis was a much more cold and uncaring place.
--> '''Jessie (About Clark)''': Who's the hottie in the primary colors?
--> '''Chloe (About Kara)''': I should have known you were Clark's cousin, what with all the primary colors.
* ColourCodedForYourConvenience:
** Clark's (and Kara's) primary colors, against Lex's more muted or darker colors.
** Clark (Red Jacket/Blue Top) and Bizarro (Blue Jacket/Red Top).
*** Though something of a subversion, since Clark has been shown in the blue jacket/red shirt combo on several previous occasions. The actual episode with both Clark and Bizarro play it straight, once we know that they're both active.
** [[GreenRocks Kryptonite]] affects Clark differently depending on what color it is.
** In Season 8, Clark only wore red and blue when operating as a hero. In Season 9, [[spoiler:after [[HeroicBSOD declaring himself "dead" after the death of Henry "Jimmy" Olsen and disappearance of Lois]], he wears black, the color he wore as Kal-El in the Season 4 opener]].
** Lana wore baby pink and baby blue for the first three seasons of the show. Then she switched to black the season she gets possessed by an evil witch. Then she started wearing either all black or all white as her character got more morally ambiguous in the later seasons.
** The proto-Justice League that forms about halfway through the series. Clark (obviously) in red and blue, Green Arrow (again, obviously) in green, Cyborg in silver, Aquaman in orange, Flash in red.
* CombatPragmatist: Clark, especially when he fights without powers. To elaborate, Clark often uses his SuperSpeed to sneak up on people to attack them. [[JustifiedTrope Often justified in that he DOES have to keep his identity secret]]. In episodes where his powers are removed, Clark turns out to be quite the battle strategist, actually.
* ComicBookAdaptation: Creator/DCComics, not surprisingly, published about a dozen issues of its own ''Smallville'' comic book. After the series ended, it began publishing ''Smallville Season 11'', following on from the events of the TV series.
* CompositeCharacter: The comic book continuation introduces a version of Batman's archenemy the Joker, who in this continuity is an evil version of Bruce Wayne from another reality, which makes him similar to Batman's Crime Syndicate counterpart Owlman.
* CompressedVice: Pete’s sudden interest in building and racing cars in "Velocity" despite never talking about it before.
* ConsultingAConvictedKiller: After someone frames Lex for the murder of his ex-girlfriend, Clark visits Lex's father in prison, wondering if he somehow managed to orchestrate this from behind bars. Lionel denies involvement, but he does help Clark figure out the killer's identity, [[spoiler:another one of Lex's exes]].
* ContagiousPowers: Everyone--'''EVERYONE'''--on the show has at one point or another gotten (and lost!) powers from: [[GreenRocks Kryptonite]], {{genetic engineering|IsTheNewNuke}}, holding onto Clark and Kryptonite simultaneously during a [[LightningCanDoAnything lightning strike]], Jor-El, Kryptonian technology, [[GrandTheftMe possession]] by someone with powers or mystically. In fact, it happens to Chloe FOUR times and three times to Lana.
* ContinuityNod: The show generally has made nods to virtually every major era/incarnation of Franchise/{{Superman}}. Ideas from the Byrne reboot, the Silver Age, the Donnerverse, ''WesternAnimation/SupermanTheAnimatedSeries'', the current comics era, and several new ideas have been blended together and all manage to co-exist on ''Smallville''.
* ContrivedCoincidence: Except some of them turn out [[ThereAreNoCoincidences not to be the coincidences]] they first appeared.
* ConvectionSchmonvection: In "Metamorphosis," Clark saves Whitney from a fireball by covering his back with his body. We actually see the fireball engulfing Whitney's uncovered front, and we are shown that the blast super-heats Clark's body to the point that his father is burned just by touching him, but Whitney is fine...somehow. Actually, the same kind of "fireball rescue" happens often enough that the show might as well be saying that Clark can extend his invulnerability to someone else by hugging them.
* CoolCar: Lex Luthor, naturally. He is always driving a car that is fast, pricey and, most of all, cool.
* CoolLoser: [[ThreeAmigos Clark, Chloe, and Pete]] are shown this way at first. They grow out of it. Chloe even becomes Prom Queen in Season 4, and Clark becomes the star quarterback. In Season 1, when Clark is running for Class President, Pete even points out that Clark is actually well-liked and has looks and charm. Pete himself is shown to have friends and respect outside of the group, likely due to being on the football team.
* CorruptCorporateExecutive: The Luthors and Tess Mercer. Oliver Queen is very much a subversion, though.
* CPRCleanPrettyReliable: in "Pilot," "Hourglass," "Accelerate," and "Hereafter."
* CrashIntoHello: A rather twisted version. For starters, Lex is driving a car when he crashes into [[MadeOfIron Clark]]. This not only is the start of their friendship, but increasingly contributes to Lex's obsession with Clark.
* CrapsackWorld: "[[ForWantOfANail Luthor]]" has an establishing shot of Earth-2, home of Clark...''[[ExactlyWhatItSaysOnTheTin Luthor]]'' ([[EvilCounterpart Ultraman]]). [[WhatCouldPossiblyGoWrong What would be the results of]] [[TemptingFate the Luthors adopting Clark]]? Well, you can [[OhCrap crap]] [[ThisIsGonnaSuck your]] [[BringMyBrownPants pants]] [[BewareTheSuperman accordingly]] [[http://smallville.wikia.com/wiki/File:Sv10x10luthorhdmkv_000659658-1-.jpg with this shot]].
* CreateYourOwnVillain: Lionel eventually becomes a better person...only to realize (too late) that his horrible parenting and the amoral value system he instilled in Lex over the years have finally borne fruit, and while Lionel is on his way to redemption, Lex is on his way to becoming an even more terrifying person than Lionel ever was. Ultimately, this comes back to bite Lionel.
%%* CreepyChild: "[[Recap/SmallvilleS02E21Accelerate Accelerate]]"
* CrucifiedHeroShot: Clark gets this trope on occasion. It starts in the pilot when he's strung up as the Scarecrow in a very literal crucifixion, he gets another in "Hidden" after being shot by Gabriel, and in [[spoiler:"Salvation" after being stabbed by Zod with blue kryptonite]]. As Superman can be seen as [[EveryoneIsJesusInPurgatory a Jesus allegory]], this makes sense.
-->'''Lex''': Clark, they left you tied to a stake in the middle of a field. Even the Romans saved that for special occasions.
%%* CuckooNest: "[[Recap/SmallvilleS06E12Labyrinth Labyrinth]]"
* DamselInDistress: Lana, Chloe, and Lois. Clark himself gets into easily as much distress as any other character. He has a more dedicated nemesis than anybody else on the show, a crippling weakness, and any number of people who want to capture him to exploit his powers/study the alien.
* DarkerAndEdgier:
** Compared to the light-hearted Season Two, Season Three ''definitely'' counts. Only in certain spots though. There are still a lot of episodes in Season Three that focus on one episode story lines that drove the first two seasons with the same mix of humour and actual peril. However, it is also the first season to focus more on big-picture elements, and it deals with the main characters going though a lot more turmoil. Clark starts off the season dealing with his dark side and living a very rough and rebellious lifestyle in Metropolis, Lex has a psychotic break (well, partly) and ends up institutionalized at Belle Reve, Chloe life's is turned into a living nightmare at times, and Pete starts to occasionally feel the bad effects of keeping Clark's secret under wraps.
** The second half of Season eight, compared to the first half. Season nine features it as well, largely as a result of the S8 finale's fallout. In general, from Season 5 onwards, the show was darker than the earlier seasons.
* DeadlyDisc: "Savior", during the fight between the Kandorian woman and Clark.
* DeadpanSnarker: Lois, Chloe, Oliver, Lex, Lionel, Tess, and on a good day, Clark.
* DeathByOriginStory: There was a comic book about Lex's childhood hero, the Avenging Angel, whose love interest became a victim of this trope. When the producers of a movie based on the comic decided to use the SparedByTheAdaptation trope on her, it motivated the [[MonsterOfTheWeek villain of the week]] to kill her actress while recording the scene where the character should die. When said villain learned of Clark's powers and how he uses them for good, the villain decided to kill ''Clark's'' love interest out of the belief a hero needs this element and a living girlfriend would be a weakness.
* DeathIsCheap: Practically everyone. Special mentions to Chloe Sullivan, who managed to die for no less than '''eleven''' times.
* DecompositeCharacter:
** The show had two different, completely unrelated versions of Dr. Hamilton from the comics.
** [[spoiler: After they killed off Jimmy, they revealed that his real name was Henry James Olsen (with Jimmy as a nickname). This gave them an excuse to then establish a [[LegacyCharacter second]] Jimmy Olsen; the younger brother of the original]].
* DenserAndWackier:
** Season Four's Lois episodes. In fact, that entire year is almost a retelling of ''Superman's Girlfriend Lois Lane'' -- right down to [[BizarroEpisode Lois becoming a witch.]]
** Season 10, much like ''Lois & Clark'', seemed to be channeling Adam West's ''{{Series/Batman}}'' in spots.
--->'''[[http://comicsalliance.com/recap-smallville-episode-10-11-icarus/ David Uzumeri]]''': My favorite part of the episode comes with [[Comicbook/{{Deathstroke}} Slade]] and Comicbook/{{Hawkman}}, actually, when Slade is like 'Look, when I named this project Icarus, I never expected an actual dude with flaming wings falling from the sky. [[RuleOfCool This is totally awesome. I love life.]]'
* DeusExMachina: Comicbook/LoisLane's "military connections" sure solve a lot of problems.
* DiabolicalMastermind: Lionel, Lex, Morgan Edge, Earth-2 Lionel, and Alexander all show aspects of this.
* DifferentlyPoweredIndividual: Called "meteor freaks", because most of them get their powers from the [[GreenRocks meteor rocks]] that came with Clark from Krypton. Chloe coined this phrase; ironically, [[spoiler:she later discovers that she herself is a "meteor freak" and rails against use of the term]], much to Jimmy's bewilderment (he wasn't in on this secret yet).
%%* DisneyDeath: "[[Recap/SmallvilleS05E03Hidden Hidden]]", "[[Recap/SmallvilleS05E17Void Void]]."
* DisneyVillainDeath: [[spoiler:Given rather unceremoniously to Lionel in the ColdOpen of "Descent".]]
%%* TheDogBitesBack: "[[Recap/SmallvilleS02E19Precipice Precipice]]"
* TheDogWasTheMastermind: In "[[Recap/SmallvilleS09E05Roulette Roulette]]" Oliver is put through a series of life and death games. Who could be responsible? [[spoiler: Chloe Sullivan,]] of course.
* DoingResearch
* DoomedByCanon: If you weren't in the comics and your name isn't [[spoiler:Chloe Sullivan]], you're probably going to die before all's said and done.
** Lex in the first couple of seasons makes sincere efforts not to be the CorruptCorporateExecutive his father is, or if he must be one of those, to at least work towards noble goals and help his friend Clark. It reached the point where they had to forcibly change his obsession from I want to be special which he had let go of, to control freak. Everything quickly spiraled down hill from there.
*** It should be pointed out that a significant one is any type of romantic relationship with Lana Lang or Chloe Sullivan. Because all fans know that [[spoiler:Lois Lane is in Clark's future.]]
%%* DoomMagnet%%
* DownerEnding: There are a LOT of them...
** "[[Recap/SmallvilleS02E08Ryan Ryan]]": [[spoiler:The specialist Clark used his powers to get fails to save Ryan, and he still dies. The final scene shows Clark leaving Ryan's hospital room, looking back on the now empty bed, and he stands in the corridor, the hospital staff walking around Clark, oblivious to his grief]].
** "[[Recap/SmallvilleS02E23Exodus Exodus]]": [[spoiler:Clark destroys his ship and the shock wave from the explosion kills Martha's unborn baby. [[WhatTheHellHero Jonathan rails at Clark for this]], and Clark leaves his parents in their grief. Chloe, jealous of Clark and Lana's growing romance, agrees to spy on Clark for Lionel. Lex wakes up midair in his private jet to find his bride gone, the pilot gone, the control consoles smashed, and his jet crashing into the ocean. Overcome with grief and guilt, Clark deliberately puts on a Red Kryptonite ring, reverting to his {{Jerkass}} Kal persona to avoid feeling any more pain. As Kal, he leaves Smallville, Lana, and his adoptive parents, seemingly for good]].
** "[[Recap/SmallvilleS03E08Shattered Shattered]]": [[spoiler:Lex is committed to a mental asylum despite Clark's best efforts to help him, and Lana's in the hospital]].
** "[[Recap/SmallvilleS03E18Truth Truth]]": [[spoiler:Chloe, after being inflicted with a truth gas made from meteor rocks, goes to retrieve her voicemail which has Lionel's confession over how he killed his parents. However, it is not Lionel's confession, but a recording of Lionel saying that he has erased the voicemail, leaving Chloe heartbroken]].
** "[[Recap/SmallvilleS03E19Memoria Memoria]]": [[spoiler:Lex recalling the truth of what happened to his brother Julian and confronting Lionel with it after an episode of flashbacks showing how their relationship began to break down from bad to terrible and increasingly destructive]].
** "[[Recap/SmallvilleS03E22Covenant Covenant"]]: [[spoiler:Kara, the Kryptonian girl Clark met, is really Lindsay Harrison, a pawn of Jor-El. Jor-El takes Clark away, Jonathan goes into a coma, Lex is poisoned, and Chloe's safehouse blows up]].
** "[[Recap/SmallvilleS04E12Pariah Pariah]]": [[spoiler:Alicia Baker, who had done a HeelFaceTurn, is murdered]].
** "[[Recap/SmallvilleS04E17Onyx Onyx]]": [[spoiler:Lex's good and evil selves are merged, but not before Evil!Lex goads his father Lionel into giving up his conversion to good. The smirk on Lex's face at the end as Lionel announces the end of the charity he founded suggests that Lex's halves merged with his evil side dominant which suggests Lex's FaceHeelTurn began here]].
** "[[Recap/SmallvilleS04E20Ageless Ageless]]": [[spoiler:Evan, the rapidly aging boy Clark and Lana grew to love, ages to the point of being an old man and dies. Lex's final line, just a few episodes after "Onyx," indicates he's now well and truly become evil]].
** "[[Recap/SmallvilleS05E12Reckoning Reckoning]]": [[spoiler:Jonathan dies]].
** "[[Recap/SmallvilleS05E22Vessel Vessel]]": [[spoiler:Lex is [[GrandTheftMe possessed by General Zod]], Clark is trapped in the PhantomZone, Lionel and Chloe are being attacked by a mob, and Martha and Lois' plane crashes]].
** "[[Recap/SmallvilleS07E10Persona Persona]]": [[spoiler:Lana is forced to admit she's been far happier in the past month with Bizarro than she's ever been with Clark...just before she kills Bizarro. Even as he knows he's dying, Bizarro tells Lana he loves her. Brainiac drains the mind of (and most likely murders) his kindly creator Dax-Ur, giving himself the information he needs to become more powerful. Lex has Grant Gabriel, the clone of his dead brother Julian, murdered before Lionel's eyes just as Lionel and Grant were starting to bond]].
** "[[Recap/SmallvilleS07E20Arctic Arctic]]": [[spoiler:Lex finally discovers Clark's secret and uses the Kryptonian Orb to bring down the Fortress of Solitude]].
** "[[Recap/SmallvilleS08E10Bride Bride]]": [[spoiler:Doomsday literally crashes Jimmy and Chloe's wedding, killing at least one person, brutally beating Jimmy into a coma, and abducting Chloe. Lois is left grief-stricken and confused, wondering why these horrible things keep happening to all of them, and left crushed when Clark, her date for the wedding who is at this point over Lana enough that this evening could be considered their first REAL date, ends up rushing right back to Lana when she shows up. Chloe is possessed by Brainiac (again). And the whole thing's being monitored by Lex Luthor]].
** "[[Recap/SmallvilleS08E14Requiem Requiem]]": [[spoiler:Lana leaves Smallville forever due to being irradiated with kryptonite and being near Clark could kill him]].
** "[[Recap/SmallvilleS08E22Doomsday Doomsday]]": [[spoiler:Jimmy dies, Davis dies, Clark [[HeroicBSOD declares himself dead]], and Zod returns as a younger, previously cloned version of the original. Not to mention Lois is accidentally transported one year into the future after a violent tussle with Tess and ''nobody'' knows what happened to her]].
** "Salvation": [[spoiler:Clark is able to send Zod and all the Kandorians away, saving Earth. However, Clark has a dagger made of [[PowerNullifier blue kryptonite]] stabbed into him and is falling to his death off the building. He gets better, though]].
* DrivenToVillainy: Several of the "meteor freaks".
* DroppedABridgeOnHim: Margot Kidder had a falling out with the producers over the writers' idea to have her character announce the death of Christopher Reeve's character. [[DisproportionateRetribution Her character was killed off.]]

[[folder: E to F]]
* EarlyInstallmentWeirdness: Several early episodes make it sound like the Luthors have been the royal family of Metropolis for generations. Later seasons would establish that Lionel Luthor was the son of Scottish immigrants and that he was born into poverty and went from RagsToRiches.
* EasyAmnesia: Occurs more often on this show than most people have hot dinners.
** The real test is when Clark does become Superman and how that will square with a substantial number of people knowing he is Clark Kent. Nearly no one knows what "The Blur" looks like, but everyone will know Superman's face.
** Used to a ridiculous grade in "Finale", when Tess simply [[spoiler: smudges a neurotoxin in Lex's face]] making him forget everything, not just Clark-related stuff; every single thing that ever happened in his life is completely and instantly erased. So much for a FreudianExcuse now.
* EcoTerrorist: Aquaman first appears as an eco-terrorist trying to stop a sonic weapon created by Lex Luthor from going into production.
* EldritchAbomination: This is [[spoiler: Darkseid]]'s natural form.
* ElectionDayEpisode: The class president election is the main focus in "Drone", and several episodes in season five revolving around the senatorial election, coming to a conclusion in "[[WhamEpisode Reckoning]]".
* ElectrifiedBathtub: At the beginning of "Red", a rogue federal agent murders new girl Jessie's ex-boyfriend this way.
* EmpathicHealer:
** [[spoiler:Chloe.]] She lost the ability later, due to a bizarre encounter with Brainiac.
** And Freak of the Week Cyrus Krupp in Season Two.
%%* EnemyMine: "[[Recap/SmallvilleS06E19Nemesis Nemesis]]"
* EngineeredHeroics: "Obscura" featured a policeman who kidnapped Chloe in an attempt to get credit for finding her. When that failed due to him and Lana having a telepathic connection, he decided he'd rather get the credit for solving the latter's murder...
* EngineeredPublicConfession: In the Season 9 finale. [[spoiler: Zod, did you forget that your followers have super hearing?]]
* EnhanceButton: Chloe pull this one in "Void". And the pic came from one of her "sources" so it's quality is pretty questionable.
* EverybodyHatesHades: In episode 10X05, Lois got possessed by Isis and tried to bring Osiris back into the world -- which, despite him being the just ruler of the dead, was treated as a very bad thing. Though it wasn't treated as a bad thing because Osiris himself was bad, but because calling him up would bring the Underworld into the real world.
* EverybodyLives: A semi-regular trope of the show, actually, thanks in part to Clark's ThouShaltNotKill policy. While a majority of episodes feature deaths, there's a substantial minority of episodes (on average, about 7 per season) where no one dies and EverybodyLives.
* EvilIsHammy: Yes. Dear god, yes. Lionel, Lex, and Zor-El all run with this trope. It's Callum Blue's performance however, as the [[ChewingTheScenery scenery chewing]] Major Zod that really proves it.
* EvilOrphanageLady: Granny Goodness uses her cover as an orphanage manager to brainwash and train girls for a future assault on Earth by Darkseid.
* EvilTwin: Bizarro and Ultraman to Clark, Earth-2 Lionel to the real one.
* {{Expy}}:
** Chloe Sullivan originally started as an Expy for Lois Lane (the actual Lois was introduced later), [[CompositeCharacter as well as the Silver Age version of Lana Lang]]. As she began to grow apart from Lois, her journalism career was downplayed and her computer skills evolved to their current levels -- making her an expy for [[ComicBook/BirdsOfPrey Oracle]].
** Tess Mercer, in her first two appearances, was referred to as both "an obscure regional VP" (unfit for her job of taking over for Lex Luthor) and a "pitbull in Prada." The first was said to her while they were up in the Arctic. The second, after she had firmly assumed control of her bald boss's former position. That's right, it's Sarah Palin. Of course, she's intended as a fusion of Mercy Graves and Miss Teschmacher (tending ''much'' more toward Mercy.)
** The episode "Warrior", turned the in-universe fictional Warrior Angel into a [[Comicbook/{{Shazam}} Captain Marvel]] Expy.
** This version of Comicbook/BoosterGold has quite a significant [[Film/MysteryMen Captain Amazing]] [[CorporateSponsoredSuperhero vibe]].
** There are some sharp similarities between Comicbook/GreenArrow's characterization and relationship with Clark, and that of Franchise/{{Batman}}. Throw in the fact that ''Film/TheDarkKnightSaga'' likely meant the writers couldn't use Bruce, and that makes a lot of sense all of a sudden. Appropriate, given that initially Comicbook/GreenArrow was very much [[PoorMansSubstitute the poor man's Batman]] in the comics, with his earliest stories featuring Speedy as a blatant {{Expy}} of Robin, as well as an Arrow-Mobile and even an "Arrow Cave."
* ExpositionOfImmortality: "Dr. Curtis Knox" is never implicitly referred to as Comicbook/VandalSavage, but that's pretty much who he is. A Civil-War era photo of a bearded Knox which Lex shows Clark confirms he's immortal, or at least older than he looks. He also tells Chloe that he was once Jack the Ripper himself. According to ''Smallville: The Official Season 7 Companion'', Dr. Knox was indeed created as the creative team couldn't get the rights to Vandal Savage.
* FailureIsTheOnlyOption: For Lex; for Clark/Lana's relationship; for Clark's desire for a normal life; for Chloe's unrequited love for Clark; for a great many things.
* FakeShemp: Michael Rosenbaum left the show after Season 7, so Lex's brief appearances in Season 8 were actually played by a body double named Kevin Miller.
* FanDisservice:
** Metallo. He's a WalkingShirtlessScene...with [[BodyHorror hideous tubing]] protruding from his ribs.
** The fangirl from "Fanatic" sneaks into Lex's place [[GoingCommando in just a trench coat]], [[spoiler:head shaved like Music/BritneySpears to resemble Lex. Yep. She's ''batshit crazy'']].
* {{Fanservice}}:
** Lois in swimsuit and {{Female Gaze}}s up Curry's torso in "Aqua" are sure to serve everyone's interests.
*** Really, any time Lois has to go "undercover" for a story, it's a pretty good bet that sooner or later she'll wind up "undercovered."
** Vala being held hostage in her underwear in the episode "Conspiracy". In broader terms, Lana and Lois did their fair share (the latter gets tons in later seasons), although not so much for Chloe.
** Also, as noted above: [[http://27.media.tumblr.com/rcSEczBP9kzlg2qq0qXyDHgVo1_500.jpg Tom Welling]], [[http://lh3.ggpht.com/_lLsdaCVk3Kk/SU1d_Ndx31I/AAAAAAAAqik/NXMAZNnhk7k/ShawnAshmore12.jpg Aaron Ashmore]], [[http://www.kryptonsite.com/bloodline103.jpg Sam Witwer]], [[http://i1.ytimg.com/vi/EPY_3CcuNmk/maxresdefault.jpg Justin Hartley]], and [[http://1.bp.blogspot.com/_RWOnrKFYUwQ/SKXB4cDIyJI/AAAAAAAAbLs/kw7XMF95xSk/s400/alan+ritchson+65.jpg Alan Ritchson]].
* FantasticRacism: Kara Zor-El dropped a few rungs on the likeability ladder when she called Comicbook/MartianManhunter "Red-Eyes." As seen [[http://www.supermanhomepage.com/tv/tv.php?topic=reviews/smallville7-ep04 here]].
%%* FantasyForbiddingFather%%
* FauxActionGirl: Played with. While many of the main female characters like Lana and Tess are repeatedly shown to be {{Action Girl}}s, their fights are generally reserved for the DesignatedGirlFight or only on men when it is convenient to the plot. Otherwise, all of their skill instantly disappears. In "Power", Tess is suddenly attacked, and instead of using her martial arts, she resorts to the typical girl-in-distress montage. She grabs a statue and plugs the guy, potentially killing him despite ([[InformedAttribute if she knows aikido]]) knowing a way to incapacitate him with pressure points and uncomfortable postures once the gun is gone. Then she gang initiation kicks him until her face is covered in blood, and the show takes pains to romanticize her rubbing it from her lips in slow motion.
* FemalesAreMoreInnocent: The show has a problem with this from time to time. However it was taken to absurd levels in "Bound", where Lex, a man who every woman he was ever in a relationship with had betrayed, being portrayed as less sympathetic than a crazy suicidal stalker and a woman who cheated on her fiancé for a one night stand. It reaches the point that the main characters were so disgusted by Lex’s actions that they were more willing to trust ''Lionel'' over Lex.
* FemmeFatale:
** Lana in "Noir".
** Tess Mercer from Season Eight onwards. She's mostly a WellIntentionedExtremist, but she still has a lot of ulterior motives.
* FetalPositionRebirth:
** The final shot of Season Three.
** Davis in "Plastique", after [[spoiler: his transformation back into a human]].
%%* TheFinalTemptation: "[[LotusEaterMachine Labyrinth]]"
* FinaleSeason: The words "The Final Season" appear above the title in the commercials for season 10. In fact, the PreviouslyOn segment at the beginning of the season premiere ends with Tom Welling's voice saying "And now, the final season of Smallville".* TheFinalTemptation: "[[LotusEaterMachine Labyrinth]]"
* FirstGirlWins: Averted; [[spoiler:despite Lana being hyped as the designated love interest, she and Clark ultimately separate]].
* FirstGrayHair: Spoofed in "Spell". The Wicked Witch, Isobel, has taken over Lana's body and needs the hair of a virgin for a potion she's brewing. When Lois has her back turned, Isobel plucks one of Lois' hairs out, but frowns upon realizing that Lois isn't a virgin. Lois, who is unaware that Lana is being possessed by Isobel, angrily asks Isobel why she would pluck one of her hairs out. Isobel lies and says "It was gray", to which Lois insists "I don't have any gray hair". Isobel shrugs and looks innocent. Lois gets a nervous expression on her face and says "I'll... be in the bathroom using your mirror," and hurries off.
* {{Flanderization}}: Chloe went from someone who was okay with computers to being able to [[ReversePolarity trace a bug's point of origin]], discover [[OmniscientDatabase anything about anyone]], and she even had a shot at decoding a Kryptonian virus on her PC... when all the power on Earth had been shut off. Basically she filled in any {{plot hole}}s where the writers couldn't think of a way to get Clark to the place he needed to be. Brainiac downloads its intellect into her, pretty much super-Flanderizing her computer skills; it turns out he was responsible for her intelligence going out of control and she was losing more and more of herself as time went on.
%%* FlatlinePlotline: "Void"
* ForcedPrizeFight: The Live or Die Fight Club in "[[Recap/SmallvilleS06E17Combat Combat]]" posts these fights on the Internet.
* ForegoneConclusion: [[spoiler:[[CaptainObvious Clark is going to become Superman]]]].
* TheForeignSubtitle: In Brazil, the series is known as ''Smallville - As Aventuras do Superboy''. That title means "Smallville - The Adventures of Superboy".
* {{Foreshadowing}}: Ironic references to the Superman mythos. ''So God damned many''.
** On a separate note, in the prologue of the pilot episode, we see a newspaper headline mentioning that the head of Queen Industries is missing presumed dead. This foreshadows [[Comicbook/GreenArrow Oliver's]] eventual appearance on the show.
** When Lex proposes to his girlfriend, the song playing in the background becomes recognizable as an acoustic cover of Blue Öyster Cult's "Don't Fear The Reaper"....needless to say, things don't end well.
** One of the biggest long term foreshadowing, apart from Clark's destiny, comes from the season 1 episode "Hourglass" when [[http://www.youtube.com/watch?v=yYRr67advsY Cassandra sees Lex's future]]: [[spoiler:He is in the White House, with white clothes and a black glove on his right hand]]. This foreshadows stuff that we only find out in the finale, almost ten years later: [[spoiler:the glove is to cover his imperfect [[CloningGambit cloned hand]], in 2018 he is elected U.S. president and he wears the same white clothes in the presidential inauguration]].
** After finding Infant!Clark in the Pilot, Martha says that she and Johnathan didn't find Clark, he found them. She's speaking poetically, but Season 3's "Relic" would reveal that [[spoiler: Jor-El did indeed send his son to the Kents on purpose, having known Johnathan's father.]]
* ForgottenFallenFriend: ''Smallville'' has always been very bad about this. In the earliest episodes, the "[[MonsterOfTheWeek Freak of the Week]]" would often be a [[RememberTheNewGuy a longtime friend the main cast would've known]] for ''years'' prior to [[WithGreatPowerComesGreatInsanity Kryptonite radiation turning them evil.]] More often than not, [[KarmicDeath they'd die.]] The main cast would spend absolutely no time mourning their loss or [[FaceHeelTurn what they had become]] even in the episode where they died.
** In later years, this would extend to {{recurring character}}s and several cases of ''series regulars'' [[spoiler: Whitney Fordman, Jason Teague, Davis Bloome]], who'd be KilledOffForReal, might be mourned in the episode they died, and then either never mentioned again or mentioned in only the briefest most casual way for plot purposes. Some particularly JustForFun/{{egregious}} examples:
*** Ryan James.
*** [[ILetGwenStacyDie Alicia Baker]]. In a two parter she and Clark fall deeply in love, she is 'the one' but thanks partly to Clark not believing she was innocent of attacking his friends she is killed by the actual baddie. The very next episode opens with Clark excited about getting a football scholarship.
*** Grant Gabriel. Lionel does mourn him. For one episode. Which is one more episode than Lois ever mourned for him, [[RomanticFalseLead even though she knew him longer.]]
*** Gina. Granted the only one who'd care would be Lex, and it's ''[[ItsAllAboutMe Lex]]'' were talking about here. Still, you'd think he'd spend at least a moment wondering who in the hell murdered his most loyal and devoted assistant?
*** Season two, Clark had a [[GirlOfTheWeek passionately romantic attachment]] to this [[MagicalNativeAmerican Native American]] [[OurWerewolvesAreDifferent shapeshifter]] with a meaningful bracelet and prophecy saying she was his soul mate, and in the end, she tragically dies. Next episode, it was like it never happened, except she had been the device for the 'caves' setting to be introduced, and ''those'' stuck around. What was her name, anyway? [[spoiler:[[ComicallyMissingThePoint Kyla Willowbrook]].]]
** Partially averted with [[spoiler: Lionel Luthor]], who's mentioned quite a bit after his death. However most of his mentions are of the [[spoiler: evil bastard]] he was at the start of the series and not as the [[spoiler:ally]] he became in the show's second half.
** Averted in the best way when it comes to [[spoiler:Jonathan Kent]].
** Also averted, somewhat with [[spoiler: Jimmy Olsen]]. His death sends Clark into a dark spiral, and Chloe isn't much better off, if at all, and Clark refusing to go back to save him, citing the example of what happened when he averted [[spoiler: Lana's death and lost his father instead]], is a key point of tension between the two of them for much of the first third of the Ninth Season.
%%* ForWantOfANail: "Reckoning," "[[Recap/SmallvilleS08E15Infamous Infamous]]," "Pandora," "Luthor."
* FourTemperamentEnsemble: The four-member ''Franchise/{{Justice League|OfAmerica}}'' team up in the episode "[[Recap/SmallvilleS06E11Justice Justice]]": Oliver [[spoiler:aka Green Arrow]] (choleric), Victor [[spoiler:aka Cyborg]] (melancholic), Clark (phlegmatic), and Bart [[spoiler:aka Impulse]] (sanguine).
* FreakyFridayFlip: Clark and Lionel swap bodies in "[[Recap/SmallvilleS04E06Transference Transference]]."
* FriendlessBackground: Lex Luthor as a child.
* FreudianExcuse: Lex's [[http://en.wikipedia.org/wiki/Narcissistic_personality_disorder hyper-manipulative, borderline-sociopathic, power-obsessed dad]] really did a number on him. Then again, in the finale [[spoiler: absolutely all his memory is erased, up to and including all his childhood memories, rendering this pretty much pointless]]. Well, presumably, his personality is still intact, so he is still the bitter, angry, cynical bastard we've all come to know, [[spoiler:even if he doesn't remember ''why'']].

[[folder: G to H]]
* GRatedDrug: "[[Recap/SmallvilleS02E14Rush Rush]]" unintentionally (victims get stung by an alien parasite), but "[[Recap/SmallvilleS02E20Witness Witness]]" is one of several cases of meteor rocks being used as such. "Void" comes with the overdue LampshadeHanging.
* GambitRoulette: Quite early in the series, in Season 1, there was a Roulette involving Lex Luthor, his father, and an old lover named Victoria. Victoria came to the Luthor mansion and led Lex to believe that she was playing on Lex's dislike for his father so that her own father could buy out [=LuthorCorp=]. Lex convinced her that they should play their fathers against each other and bring them both down. Lex cultivated a romantic relationship with Victoria and when they went into business talks with Victoria's father, he said that he was poised to buy out [=LuthorCorp=] thanks to Victoria's intelligence she gathered from Lex's computer. However, Lex had already made sure that Victoria's father's endeavors would be useless and unfruitful. Lex and his father bought out Victoria's father's corporation, but in a surprising twist, [[spoiler: it was revealed that Victoria was a lover of Lex's father and working for him the whole time]].
* {{Gaslighting}}: Happens to Lex after he was lost on an island and during "Shattered".
* GaussianGirl:
** The first appearance of Kara -alias Comicbook/{{Supergirl}}- shows her blurred and in a flowing white dress. Under water. When she saves Lex Luthor and flies away, he is convinced she is an angel who is there to make him repent his sins.
** The sequences within the Fortress of Solitude in all get a bit Gaussian...
* AGlassOfChianti: The Luthors, constantly. Major Zod too.
* GlowingEyesOfDoom:
** [[spoiler:Davis Bloome]]
** And [[spoiler:Martian Manhunter]]. Although he's one of the good guys, so it's not really "of doom".
** Clark also gets these on occasion when he's on red kryptonite.
* GodTest: Tess orchestrates one in "Turbulence".
* GovernmentConspiracy: Checkmate is one; the Comicbook/SuicideSquad is the remnants of one. The government went above board with the Vigilante Registration Act and General Slade Wilson spearheading it, [[spoiler: although the public is still in the dark about the government constructing concentration camps for the superheroes]].
* GrandFinale: "[[ExactlyWhatItSaysOnTheTin Finale]]".

* GreaterScopeVillain: [[spoiler:[[SealedEvilInACan General Zod]]]] to Brainiac in Season 5.
* GreenRocks: {{Trope Namer|s}}. The kryptonite fragments left all over Smallville have had dozens of different effects, ''not including'' individual powers bestowed, depending on what else is present in the immediate area when an individual is exposed. Which is how the human "freak of the week" in the first two seasons got their powers, usually them having to be at the point of death when exposed.
* GroundhogDayLoop: "Reckoning." Subverted in that the loop only repeats once and the only thing Clark's able to change is [[spoiler:which person he loves dies that day. Originally it was Lana. In the loop, it's Jonathan.]]
* HappilyAdopted: Clark has boatloads of angst over his Kryptonian heritage, but he loves his parents and considers them his real family. He even explicitly says in "Rosetta" that no matter what he finds out about his people, the Kents will still be his mom and dad. He has also told Jor-El that Jonathan is his real father and never calls Jor-El "father". [[spoiler:Except in "Abyss".]]
* HappilyMarried: The Kents.
* HardHead: ''Smallville'' is the ''king'' of this trope. Lex and Lana have each been knocked out almost ''50 times''.
* HeWhoMustNotBeSeen: Despite numerous allusions to his famous alter ego, we never see Clark in full Superman regalia. [[spoiler: Except right at the end of "Finale". Quite appropriately really. Although given that it is entirely CGI other than his face...]]
** Even in ''Finale'', we only see Clark in the Superman suit in ''extreme'' long shots (where he's probably a CGI double), or ''extreme'' closeups where it's just his face with some blue and red barely visible at the shoulders. Even the final shot ends with Clark just ripping open his shirt to show the S emblem underneath. Tom Welling wearing an actual Superman costume is never shown at any point in the entire series.
* HealingFactor: The Kryptonians, Curtis Knox and Lex possess it. Certain drugs can temporarily give anyone this power, [[PsychoSerum with side effects]]. For a while, [[spoiler:Chloe]] had not only the power to heal herself but to heal others, even resurrect them. She saved Lois' life once. She later lost that power because of Brainiac.
* HeelFaceDoorSlam: Lex Luther has actually attempted to perform a HeelFaceTurn numerous times throughout the series but has always been trusted back into the world of villainy. Usually through the actions of the heroes though mainly Lana.
* HeelFaceTurn:
** [[spoiler:Lionel]], who eventually becomes a [[spoiler:[[ParentalSubstitute father figure]]]] for Clark. It was mostly a case of Clark redeeming him. While Lionel still had ulterior motives, for the most part by Season 7, he was genuinely concerned with making sure the world didn't end as a result of Lex's various insane quests, and Clark was naturally the best means to accomplish this.
** In "Homecoming", [[spoiler: both Brainiac (5) and Greg Arkin (the villain of the second episode of the series who returned to his high school reunion to thank Clark for helping him overcome his madness)]].
** [[spoiler: "Alexander Luthor"/LX-15, one of the Lex clones,]] in "Beacon".
** [[spoiler: Tess]] does one in the finale of season 9, eventually joining the team in season 10.
* HeroicBSOD: [[spoiler:Clark]], at the end of "Doomsday".
* HeroicSacrifice: Thanks to Jor-El, Clark is able to do this several times. It's practically one of his powers in the series.
* HesAFriend: Clark tries to do this between his cousin Kara and ComicBook/MartianManhunter. [[spoiler:It didn't end well.]]
%%* HighSchoolDance: "Spirit"
* HollywoodNerd: Clark, Chloe, Jimmy, Emil.
* HorrorHunger: Season One's "Craving" most definitely.
* HotScoop: Lois. Chloe was this at first, but she arguably fits NerdsAreSexy better now that she's all but ditched her journalism career.[[spoiler:..except she returned to it later.]]
* HugeGuyTinyGirl: Clark is a tall strapping guy and most of the women in his life are fairly petite but of course Clark and Chloe are the exemplars.
* HumanAliens: Clark. In fact, ''all'' of the aliens shown either look human, are [[VoluntaryShapeshifting shapeshifters]] posing as human, or disembodied beings [[BodySurf possessing human bodies]].
* HumansAreTheRealMonsters: Episodes like "[[Recap/SmallvilleS02E12Insurgence Insurgence]]," "[[Recap/SmallvilleS02E13Suspect Suspect]]," and "Precipice" are completely meteor-freak-less. Also, "[[Recap/SmallvilleS05E14Tomb Tomb]]" [[spoiler:has a girl raised from the dead by a meteor rock bracelet ([[LightningCanDoAnything and a bolt of lightning]]) to go after an AxCrazy but otherwise ''human'' psych ward orderly. Who, y'know, ''put her there in the first place'']].
* HurricaneOfPuns: Often happens in discussions of the freak of the week.
* {{Hypocrite}}: Pretty much everybody from [[TheHero Clark]] and [[LoveInterests Lana]] to [[BigBad Lionel Luthor]].
** The worst example, however, has to be Lex, who constantly bitches about Clark keeping his secret from him, while simultaneously keeping an army of skeletons (all of them far, far darker than Clark's) in his own closet.
** Lana complains constantly about Clark and Lex hiding things from her, but the minute she has a secret (the black spaceship, the fact that Lex is still alive, etc.), she goes out of her way to hide it from Clark. Which also makes her TooDumbToLive, since in those situations Clark is probably the ''first'' person she should be talking to, as he actually has a proven track record of saving her from these situations.
** Clark is perhaps the biggest example: he expects everyone else to be completely honest with him about everything, but builds his relationships around lies and deceit, insisting on keeping his "secret" even among his closest friends. That's probably why he's so touchy about lies; he knows people keep secrets and that somebody can be deceiving you even when it doesn't seem like it--he does so himself. Lampshaded in "Zero," where he chews out Chloe for snooping around in his past, then ''immediately'' invites her to join him in snooping into Lex's. Chloe does a double-take.\\
*** He admits that his reactions to things are what keep people from telling him things in "Luthor." He starts the episode off by telling [[spoiler:([[DramaticIrony secret]]) Luthor Tess]] that all Luthors are dangerous and evil. He then is furious and offended when he finds out that she hid Lex's clone from him. He then disappears [[AlternateUniverse into the plot]] before [[spoiler:Tess can admit to her heritage]], so we don't know how he would've taken that. At the end of the episode, however, he's realized that blaming the entire Luthor bloodline for Lionel's influence is the exact reason why [[spoiler:Tess didn't tell him the truth]], so he stops being a jerk about it.
** In "Nocturne," he peevishly comments that Lana's [[ObsessiveLoveLetter Secret Admirer]] sounds like a stalker. This, from Mr. Peeping Telescope.
** Clark gets a lot of heat in the start of season 3, acting like a totally different person under the influence of red Kryptonite. The thing is, ''the same thing happened'' to Chloe in "Devoted", Lana in "Spell" and Lex in "Onyx" later in season 4. Either Clark can't bring himself to call them out on it, or it never occurred to him.

[[folder: I to J]]
* IJustWantToBeNormal: Yeah, good luck with that. Clark has gotten a lot better about this. In fact, by Season Eight it's fully gone, though [[spoiler:in "Hex", when Zatanna granted his deepest wish he lost his powers and his memory of them, (Chloe was able to snap him out of it.)]] In Season Nine, it's even less likely he wants to be normal, as he has accepted his destiny to help humanity with his powers. This could be considered as part of the character growth as a virtual human raised by humans who is on the cusp of fully accepting who and what he is and thus becoming Superman. Even the "incident" with [[spoiler: Zatanna]] is treated less like Clark wanting to give up his abilities completely, and more like just wanting to take a vacation in the land of the ordinary human for a day or two.
* IJustWantToBeSpecial: Pete, Lana.
* IWantYouToMeetAnOldFriendOfMine: Played straight when Jonathan Kent (John Schneider) is the one introducing us to Senator Jennings (Tom Wopat), both from ''Series/TheDukesOfHazzard.''
* IllKillYou:
-->'''[[EvilTwin Clark Luthor]]''': Give me the box.
-->'''Tess''': And if I don't?
-->'''Clark Luthor''': I'll kill you.
* IdenticalGrandson: In "Relic", Clark's father and Lana's great-aunt are portrayed by Clark and Lana's respective actors. Lana's distant ancestor Countess Isobel also looks just like her.
* IdentityImpersonator: Clark, on behalf of Oliver. Oliver later repays the favor.
* IdiosyncraticEpisodeNaming: They always use one-word titles.
** Surprisingly {{averted|Trope}} with "Absolute Justice", the two-hour special. But then again, it ''was'' a double length episode. It also forced them coming up with more and more elaborate synonyms for [[NotHimself "Red"]]. Like "Crimson".
*** Played straight when you consider that the two individual episodes "Absolute Justice" is comprised of are named "Society" and "Legends", and thus stick to using one-word titles.
* IdiotBall: This also has the UnfortunateImplications to often be combined with HystericalWoman. In "Nemesis", a military officer who is able to conduct CIA style informational espionage kidnaps Lex and rigs 5 miles of explosives because she knows her husband is alive.
* IfYouKillHimYouWillBeJustLikeHim: Or so Lana tells Clark (regarding Lex) in Season Eight's "Requiem".
%%* ImYourBiggestFan: "[[Recap/SmallvilleS05E10Fanatic Fanatic]]"
* ImmuneToFate: In "Hereafter" a boy named Jordan can foresee the death of anyone he touches but is powerless to change it. When he touches Clark he doesn't see a death, however, just Clark going on "forever". Then Clark proceeds to save someone from the death that Jordan has foreseen. This leads them to conclude that Clark has the power to change predestined events.
* ImportantHaircut: Lana in Season Eight's "Power". Lionel, in prison, as classical music plays in the background.
* ImprobableAimingSkills: Green Arrow, [[EvilCounterpart Dark Archer]], Clark (watch whenever he throws an object), Deadshot. Justified with Clark as that is one of Superman's powers. A basic comic book trope [[CharlesAtlasSuperpower even with superheroes without superpowers, just extraordinarily skilled athletes.]]
* ImStandingRightHere: In "Kara", ''[[Comicbook/{{Supergirl}} Kara]]'' insults Chloe by saying she is "[[PunyEarthling just a human]]" condescendingly when she is standing right there; Clark defends her by saying [[TheSmartGirl Chloe is smarter than both of them put together]].
%%* InAnotherMansShoes: "[[Recap/SmallvilleS03E06Relic Relic]]"
* InNameOnly:
** While Smallville is full of different takes on the featured comic book characters, Cat Grant is absolutely nothing like her comic book counterpart. In the comics, she started out as a promiscuous gossip columnist and later became a cougar with breast implants and low cut blouses where the TV version actually spells the word "sex" at one point because she's too uptight to say it and is actually kind of pudgy and conservatively dressed. All this to turn her into a [[StrawCharacter Straw Conservative]] where the comic book version couldn't care less about politics.
** Slade bears very little resemblance to his comic book counterpart, ComicBook/{{Deathstroke}}. He's actually much closer personality-wise to [[GeneralRipper Wade Eiling]] or Marvel's [[ComicBook/XMen Senator Kelly]].
* InformedAttribute: Throughout Season 9, Zod frequently claims that Kryptonians have superior intelligence to humans, despite the fact that they juggle the IdiotBall and VillainBall nearly all series long and make a symphony of blunders and bad decisions.
* InsaneTrollLogic:
** Albeit not as strong of an example as others have been, one episode has Jimmy figuring out Clark's secret as a vigilante. The general train of logic goes something like this. Jimmy takes picture of blurred red figure (Clark saving both him and Lois from a mugger using superspeed in his typical red jacket), Smallville has people being saved from various "accidents" (past episode kinds of things), then after seeing a picture of Clark in his red jacket, thinks Clark is the vigilante. While the end conclusion is correct, the train of logic/actions taken to figure this out is wildly weird. It's reasonable to start looking in Smallville first, seeing that most of the incidents occurred over in that area. But the real head turner is how he managed to pinpoint Clark of all people as the Blur. [[SarcasmMode Because he's clearly the only person on the planet who wears a freaking red jacket.]]
** Lana’s notion in "Power" that she had finally become Clark's equal after gaining power through selfishness, money, lies, and near suicide.
** Pete in "Nicodemus". Just watch his thought process when he came to the conclusion that if he killed Lex Luthor Chloe would like him.
* InSeriesNickname:
** Lois usually calls Clark "Smallville", but "[[EmbarrassingNickname Clarky]]" on rare occasions. Lois almost always just call Chloe "cous" (as in, "cousin") or "Chlo,"[[note]]Many FanFic writers picked this up to use as an AffectionateNickname from whoever they are pairing Chloe with[[/note]] or more rarely "Goldilocks". She once calls Jimmy "Baby Bear", and he is not happy.
** Chloe sometimes call Lois "Lo".
** Jimmy sometimes call Chloe "[[AffectionateNickname Brighteyes]]". And yes, she has eyes that you can't stop staring at.
** Chloe's boss at the Daily Planet used to call her "Chloster". Jimmy picked it up. She is not amused.
-->'''Chloe''': How much blunt trauma do you think a stapler to the back of the head would cause?
** The names ComicBook/MartianManhunter and Comicbook/{{Supergirl}} starts out as Chloe's nickname for them in ''Smallville''. She is also known for calling Clark the Man of Steel.
** Oliver started the tradition of calling Clark "Boy Scout" and Bart "Impulse". Bizarrely, Brainiac sometimes also call him that, but he always refer to him as Kal-El face to face.
* InstantExpert: Lana's martial arts skills. She was trained by Lex in the early seasons and worked out much like Tess did later, including wearing boxing gloves and hitting the heavy bag. The episode we see Lana being trained by Lex has her facing a guy who'd been threatening her, and kicking him so hard he's knocked into a table and ends up unconscious. She couldn't have had more than a few days practice with Lex until that point. Basically anything Lana tries, she becomes this. Even when she gains Clark's abilities she knows how to use them instantly; it took Clark years to master his powers. This is especially jarring since Eric Summer didn't instantly master those abilities.
* InstantSedation: Has happened multiple times to almost every female regular, but the hands-down winners are Chloe, Lana, and Lois. Basically, if you're a female character who's attracted to Clark, chances are it'll happen to you. Combines naturally with DamselInDistress for maximum effect.
* InterchangeableAsianCultures: Isobel finds ''a sai'' in a Chinese temple in "Sacred".
* InterspeciesRomance: Clark and any of his girlfriends, as well as Bizarro/Lana. Other Kryptonian-human relationships also apply.
* IntrepidReporter: The show is saturated with these. Chloe and later Lois and Clark are the most prominent examples.
* InvoluntaryShapeshifting:
** [[spoiler:Davis is actually Doomsday in disguise, and gradually loses control over his alter ego.]]
** This also happens to Bizarro as well whenever he's exposed to sunlight, revealing his true nature as [[spoiler: a Phantom who stole some of Clark's DNA in order to gain his appearance]].
* {{IronicEcho}}:
** Listen to Clark's explanation to Lana in seasons 1-3 about why he can’t be truthful. Then listen to Lana’s explanation to Adam about why she left Paris.
** After Lionel puts Lex in Belle Reeve for electrotherapy, watching him in a straitjacket from behind two-way glass, it's Lex's turn to watch Lionel in a straitjacket from behind two-way glass after having one of the season's {{MacGuffin}}s on his person when it activates causes him to go catatonic. [[CallBack They even keep the camera angles and everything.]]
** After all the grief Clark gets for not telling Lana the truth about himself, the end of season 5 has Lex developing similar powers from a syringe [[spoiler:by Brainiac, to prepare him to be Zod's vessel]]. He then goes on to [[spoiler:rub it in everyone's faces by reusing Clark's reasons when he tells Lana]].
* IsNothingSacred: In the episode "Hero".
-->'''Clark Kent:''' I found the source of Pete's powers. Kryptonite-enhanced gum. I found a whole stockpile.
-->'''Chloe Sullivan:''' Chewing gum? Is nothing sacred anymore?
* ItAlwaysRainsAtFunerals: It rained heavily during the funeral of Whitney's father, but for everyone else, it was a subversion. It snowed at Jonathan Kent's funeral; It was a bright sunny day at Henry James "Jimmy" Olsen's funeral; and it was also sunny at [[spoiler: Carter Hall]]'s funeral in Egypt in "Luthor", albeit was held indoors.
%%* ItsAWonderfulPlot: "Apocalypse"
* IvyLeagueForEveryone: Clark has a scout from freakin Princeton come to see him in a season 4 episode...for football, even though Princeton isn't known for its football program. Thankfully the show actually subverts this.
%%* JourneyToTheCenterOfTheMind: "Labyrinth," "[[Recap/SmallvilleS07E12Fracture Fracture]]," "Pandora."
%%* JumpingOffTheSlipperySlope: "Requiem", "Doomsday."

[[folder: K to L]]
* KarmaHoudini:
** Lex and Oliver after it was revealed in season 6 episode "Reunion" that he indirectly causes the death of one of the classmates that he bullied though no one calls him out on it, not even Clark.
** Lana Lang is probably the ultimate example of this. She has kidnapped and tortured an old man, ran a shadow organization, spied on an old lover, beat him senseless, knocked out people at a major press [[DisproportionateRetribution who will not run one of her stories]], released Brainiac into the world, and got away with it all as she did it to help the person she loved.
* KeepingSecretsSucks: Lana's motto, which she repeated to Clark over and over from Seasons 2 though 6… not that it stopped ''her'' from keeping her own big secrets during that time period. Chloe in particular gets a lot of pressure from Lana when the latter (finally) figures out Chloe is protecting Clark.
* KickTheDog: Lex does this more and more as the years go by: he begins lying, cheating, and stealing to get his hands on the Kryptonian artifacts, and the following season begins kidnapping and torturing superpowered characters. He also sends a band of superpowered murderers to kidnap the Kents and Lana in a selfish (and dangerous) attempt to force Clark to reveal his powers against his will (this ends up destroying his friendship with Clark once Clark finds out it was Lex who orchestrated the whole thing), and eventually Lex begins murdering people to get what he wants.
** Going up to someone who’s HappilyAdopted with a picture and telling them that their real father was a murderer then getting mad when they don’t want to hear it.
* KilledOffForReal:
** Main/recurring characters who died include Whitney Fordman, Dr. Virgil Swann, Jason and Genevieve Teague, Sheriff Nancy Adams, Jonathan Kent, Lionel Luthor, Henry James "Jimmy" Olsen, and Davis Bloome.
** Lex was thought to likely be a case of NotQuiteDead or NeverFoundTheBody. It turns out that Lex really ''was'' dead after Oliver killed him; Earth-2 Lionel Luthor, however, brought him back through a [[DealWithTheDevil deal with Darkseid]], at the cost of his ''own'' life and soul.
* KlingonPromotion: By Season 7, Lex really, really wants to be evil. But he just can't pull it off convincingly. The solution? Kill the [[BigBad biggest baddie]] around, [[spoiler:Lionel Luthor]]. Also a case of DyingToBeReplaced.
* KneelBeforeZod: Naturally. In the case of the season six premiere, Clark responds with an instance of ISurrenderSuckers. And in the Season 9 finale, the {{Trope Namer|s}} himself turns it into a BadassBoast:
--> '''Zod''': Unlike you, I would rule from a throne, not the shadows. Every human on this planet, including the woman you love, will kneel before Zod!
** Flipped in Season 9, when Major Zod commands his troops to "Kneel before Kal-El."
* KryptoniteFactor
* KryptoniteIsEverywhere: [[UpToEleven Brought up to ridiculous levels.]]
* KungFuSonicBoom: Whenever Kryptonians battle.
* LargeHam: Lionel (and the Earth-2 version even ''moreso''), both Zods, Rick Flag, Zor-El.
* LaserGuidedAmnesia: All the time: a convenient cop out whenever ''anyone'' discovers Clark's powers.
** To the point where whenever somebody doesn't forget Clark's secret, it's a surprising subversion.
* LastGirlWins
* LeaningOnTheFourthWall: The Legion of Super-Heroes episode did this a lot. For example, surprised at Clark not being Superman, Lightning Lad expresses dislike at the "No tights, no flights!", and they mention [[spoiler:that they've never heard of [[CanonImmigrant Chloe]]]]. Possibly also a MythologyGag in reference to the Legion visiting Comicbook/PostCrisis Superman for the first time and being surprised at how he was not the Superman they were expecting. That story was a pivotal attempt at explaining how the Legion could remain non-retconned after the retconning of Superman removed his Superboy adventures. It didn't work.
%%* LegionOfDoom: "[[Recap/SmallvilleS08E21Injustice Injustice]]"

* LetsSplitUpGang: Clark and Kara in the S&M club in "Supergirl".
* LetsYouAndHimFight: How the first meeting between Clark and another superhero usually goes.
* LightningCanDoAnything:
** In "Leech", "Asylum" and "Wrath", GreenRocks and lightning team up for PowersAsPrograms.
** "Crisis". Lightning, GreenRocks and a telephone line lets you ''call back in time''.
** "Tomb". Substitute the telephone line for [[spoiler:a dead body hidden in the Talon bathroom wall, [[OurGhostsAreDifferent and poof, instant ghost]].]]
* LikeParentLikeSpouse: Isn't it a little peculiar how much Lex's mother looked a lot like, and sounded a lot like, Lana?
* LimbSensationFascination: One episode has Lionel and Clark switch bodies; Lionel then admires his new body in a mirror.
* LimitedWardrobe: A side-effect of ColourCodedForYourConvenience -- Clark's blue shirt and red jacket combo. Every time he wears something else, he's probably at work, it's a special occasion, or he is evil/"dead". [[LampshadeHanging It got to the point]] where, in one episode, Jimmy, seeing a red/blue blur caught on camera, came to the conclusion that it was Clark going around saving people, just based on the colors.
** That episode also included a scene where Clark gets all his clothes out to sort the red and blue ones from the rest and dispose of them, only to discover that they are all red and blue.
** By Season 9, Clark doesn't wear any red and blue on his uniform, though sometimes in his everyday clothes.
*** Perhaps made fun of in the Season Nine episode "Warrior", where Clark goes to the ''Smallville'' universe's version of Comic Con. We see somebody wearing what looks like Clark's red and blue. This would mark the first time Clark has worn red and blue since "Doomsday" (the Season Eight finale, which was over eleven episodes ago)... if it weren't for the fact we see Clark bump into the guy wearing what looks like his old outfit, and is wearing his ''Daily Planet'' suit.
*** Clark was in a major funk after the episode "Doomsday", feeling responsible for the death of Henry Olsen and regretting his humanity, so he took on an all black motif until early in season 10 where he is wearing at least maroon and blue.
* LiteralChangeOfHeart:
** In "Cure", Knox tries to do this to [[spoiler:Chloe.]]
** Darkseid takes [[spoiler:Lionel]]'s heart out and plants it in [[spoiler:the Lex clone's body]].
* LonersAreFreaks: Subverted in "Hug," with Lana and Whitney automatically assuming that the local hermit is responsible for Lana falling off her horse simply because he happened to be around at the time (Lana so strongly believes in his guilt that she turns on Clark when he isn't prepared to judge as quickly). As it turns out, it really was just an accident and the episode's true villain is a FauxAffablyEvil CorruptCorporateExecutive who prides himself on (pretending to) being everyone's buddy.
* {{Long Runner|s}}: After running for ten years, ''Smallville'' beat ''Series/StargateSG1'' as the longest running American Sci-Fi show[[note]] It surpassed it on May 6, 2011, and the series finale aired a week later on the 13th[[/note]] . The difference in length is only ''three'' episodes, however, and the ''SG-1'' movies ''[[Film/StargateContinuum Continuum]]'' and ''Film/TheArkOfTruth'' put it over the top if counted.
* LoveAtFirstSight: In "Fierce", Kara has an immediate crush on Jimmy Olsen that triggers her heat vision, which is caused by sexual thoughts.
* LoveIsInTheAir: "Heat"
* LoveMakesYouCrazy[=/=]LoveMakesYouEvil: Many of Lana's UnwantedHarem of stalkers.
* LoveMakesYouDumb: Clark towards Lana. Chloe towards Jimmy. [[RuleOfCautiousEditingJudgment Let's just leave it at that.]]
* LovePotion: "[[Recap/SmallvilleS04E04Devoted Devoted]]" has a slight twist on the usual formula, as anyone who already has a true love grows even more devoted to the person they're infatuated with.

[[folder: M to N]]
* MagicFromTechnology: Kryptonian technology was mistaken for magic on medieval Earth, and can boost Countess Isobel's real magic somehow.
* MagicMeteor: Superman himself may not count, but the MonsterOfTheWeek was often a "meteor freak", i.e. got their power from exposure to Kryptonite.
* MagicalComputer: Much to the heroes' delight, Chloe is a hacking pro.
* MagicalDefibrillator: In "Fever", doctors defibrillate a flatlined patient.
* MakeWayForThePrincess:
** Invoked in "Spell". Apparently this trope goes back to [[OlderThanSteam Margaret Isobel Thoreaux's time.]]
** We get the more traditional version in "Spirit". Yeah, you heard me, a ValleyGirl in ''Kansas''.
* MalfunctionMalady: How Clark discovers his super breath. And superhearing too, if you think about it.
* MarkedChange: Clark branded by Jor-El, Lana getting her ancestor's witch-mark.
* MassSuperEmpoweringEvent: Kryptonite -- it's not just for killing superheroes anymore!
* MaybeMagicMaybeMundane: "Void" is about a serum that brings a person near death, giving them visions of their loved ones that have passed on. Which could merely be drug-induced hallucination and nothing more, [[spoiler:but then the "vision" of Jonathan Kent tells Clark something that ''Jonathan didn't live to tell anyone'']].
* [[ProphetEyes Milky White Eyes]]: Both Lana and Chloe get it when they are [[spoiler:put into painful comas by Brainiac]].
* MindManipulation: Several Meteor Freaks have this power, or [[MoreThanMindControl something similar]].
* MinorCrimeRevealsMajorPlot: "Blank" starts off with the [[MonsterOfTheWeek freak of the week]] using his LaserGuidedAmnesia powers to steal money. Then Clark is wiped, and the boy's powers are revealed to be the result of a botched procedure to alter his memories after his brother was killed by a shot from his own gun. Which later turns out to be implanted memories by his father, ''who created the procedure at Summerholt''. At least there's some positive fallout, as the law finally clamps down on Summerholt in the end.
* AMinorKidroduction: The first episode's prologue is this to [[Franchise/{{Superman}} Clark Kent]] and Comicbook/LexLuthor.
* MonsterOfTheWeek:
** The show has [[GreenRocks Meteor Freak of the Week]], mutants created by kryptonite. Season 6 also gave us the Phantom Zone escapees-of-the-week. As the series has progressed, it has much more of a StoryArc, but often keeps the Monster of the Week format.
** It also had an interesting variation starting in Season 4: ''Hero'' of the Week. Every season would have about two or three episodes where a superhero or two from the comics would guest star, run amuck, get on Clark's bad side, then ultimately they'd make their peace and help each other out before leaving in a manner that some could interpret as a PoorlyDisguisedPilot.
* MorallyAmbiguousDoctorate: Metropolis University must be the world's leading college for obtaining a MorallyAmbiguousDoctorate, because almost every single doctor appearing on the show is either evil or a WellIntentionedExtremist doing unethical experiments ForScience (or, y'know, in return for Luthor money). Even a regular medical doctor [[spoiler: Helen Bryce]] turned out to be evil in Season 3.
* MoralMyopia: In Hero Chloe goes to Lex's office and yells at him about stealing her files despite the fact that she has repeatedly stole information in the past.
* {{Mordor}}: The Phantom Zone is a desolate wasteland populated by Krypton's worst criminals, many of whom are Phantoms, seeking new bodies. Nothing grows, the wind always blows at gale force, and the terrain is treacherous. It actually gets worse in Season 10, when General Zod seizes control of it in the name of ComicBook/{{Darkseid}} and carves out a hollow empire from it ruins, forces many of the residents into his army, and institutes a brutal series of gladiatorial games that prune out those who nature and their fellow criminals have missed.
* MotiveDecay:
** Jason Teague. [[spoiler:He goes from refusing to help his mother after learning she may be manipulating him and Lana, to being a fully clued-in accomplice to her plan and treated as though he always was. It smacks of rushing him out of the show.]]
** Similarly, Davis Bloome's transition from good-hearted paramedic to completely-unstable killer that [[spoiler:murders Jimmy when he realises Chloe doesn't love him]] reeks of contrivance, simply to make Clark leave at the end of Season 8 because HumansAreTheRealMonsters. Many people were upset, including Bloome's actor.
* MrFanservice: [[http://27.media.tumblr.com/rcSEczBP9kzlg2qq0qXyDHgVo1_500.jpg Tom Welling]] (he actually has lots of shirtless scenes...), [[http://lh3.ggpht.com/_lLsdaCVk3Kk/SU1d_Ndx31I/AAAAAAAAqik/NXMAZNnhk7k/ShawnAshmore12.jpg Aaron Ashmore]], [[http://www.kryptonsite.com/bloodline103.jpg Sam Witwer]], [[http://hunkforo.com/wp-content/uploads/2011/04/Justin_Hartley06.jpg Justin Hartley]], and [[http://1.bp.blogspot.com/_RWOnrKFYUwQ/SKXB4cDIyJI/AAAAAAAAbLs/kw7XMF95xSk/s400/alan+ritchson+65.jpg Alan Ritchson]], to name a few.
* MsFanservice: Erica Durance, Kristen Kruek, Allison Mack, Cassidy Freeman. . .
* MundaneUtility: Clark has been known to use his heat vision to make toast, heat up coffee, and light candles. He also uses his super strength to drive nails with his bare hands, plant fence posts, and lift cars and tractors instead of using a jack. In "Lexmas", Chloe recruits Clark for an emergency... using his super speed to deliver Christmas presents to thousands of children in Metropolis.
** Clark, during one of his more JerkAss moments, actually accused Jonathan and Martha of exploiting his abilities to keep the farm running more cheaply and efficiently than hiring extra hands or buying new farm equipment. JerkAssHasAPoint is ZigZagged, as the chores his parents give are typical farm labor, and could be done perfectly well with the tools on hand, Clark's abilities just let him do them faster and more efficiently.
* MythologyGag:
** Countless references to the comic book continuity, such as Clark considering naming his dog Krypto.
*** Another possible name is Skip. In the Silver Age Superboy comics, Krypto goes by the name "Skipper" as an ordinary Earth dog.
** Annette O'Toole cast as Martha Kent after playing Lana Lang in [[Film/{{Superman}} the movie series]]; Christopher Reeve, Helen Slater, and Margot Kidder guest spots. Terence Stamp voicing Jor-El.
*** [[spoiler:[[MusicalNod And John Williams' theme playing during the final scene of the]] GrandFinale.]]
** Dean Cain of ''Series/LoisAndClark'' has made a guest appearance, and Teri Hatcher appeared as Lois' mom in Season 10.
** ''Series/WonderWoman'''s Lynda Carter showing up as Chloe's mom.
** Several references are made to [[Franchise/{{Batman}} Gotham City]].
*** Carter Bickson from the Deletion Force mentioned that there was a Level Three facility in Gotham City. (''Chronicle'')
*** Oliver Queen's friend Geoffrey says he has to return to Gotham right before he gets in his limo. It then explodes. (''Reunion'')
*** Linda Lake taunts Chloe by saying she can see Gotham from her new office. (''Hydro'')
** Bart Allen, the Smallville-verse Flash, has fake [=IDs=] in the names of all the other [[Franchise/TheDCU DC Universe]] Flashes (Wally West, Barry Allen and Jay Garrick) in his first appearance. Now flash forward to The JSA in Season 9 and Jay Garrick...
** Chloe mentioned a "[[Franchise/WonderWoman wondrous woman]]" and "[[Franchise/{{Batman}} a billionaire with lots of neat toys]]".
** The Season 3 ep "Crisis", which actually references a teen crisis hotline, while nodding at how Creator/DCComics really likes the word 'ComicBook/{{crisis|OnInfiniteEarths}}'.
** A Brainiac-infected Chloe is a lot like the Brainiac-13-infected Lena Luthor and [[ComicBook/KingdomCome Brainiac's Daughter]].
* {{Nanomachines}}: Brainiac's physical form is composed of millions, possibly billions, of these.
* NetworkRedheadedStepChild: Smallville became this after Creator/TheWB was replaced by Creator/TheCW; network president Dawn Ostroff seemed to utterly despise sci-fi shows, and only kept ''Smallville'' and ''Series/{{Supernatural}}'' around because they were the two highest-rated shows on her network, not out of any affection. During her tenure, half the show's budget was cut and given to her favorite shows instead, writers were often fired between seasons, and ''Smallville'' and ''Supernatural'' often received zero promotion from the network, which was way more interested in pushing shows like ''Literature/GossipGirl'' and the ''Series/BeverlyHills90210'' and ''Series/MelrosePlace'' remakes. On one occasion, the network president was questioned about this, to which she retorted "''Gossip Girl'' is the phenomenon"...despite ''Smallville'' still being the network's ratings leader.
* NeverGetsDrunk: In "Turbulence", we learn that Clark is either physically incapable, or needs astronomically ''huge'' quantities to get there. Or when the alcohol is magically charmed, as in "Fortune". Also an allusion to Superman's weakness to magic.
* NeverMyFault:
** Pete blames everyone else for his problems from Lex for what his father did to Clark for having powers and not using them to help him lie cheat and steal.
** The main villain in "Bound" for her ruined relationship despite the fact that she cheated on her fiancé in a one night stand with some random man she met in a bar.
* NewNeighboursAsThePlotDemands: Season Three's "Slumber", among others.
%%* NewSuperPower: "[[Recap/SmallvilleS01E04XRay X-Ray]]" (x-ray vision), "[[Recap/SmallvilleS02E02Heat Heat]]" (heat vision), "[[Recap/SmallvilleS03E10Whisper Whisper]]" (super-hearing), "[[Recap/SmallvilleS06E02Sneeze Sneeze]]" (super-breath), "[[Recap/SmallvilleS10E21E22Finale Finale]]" (flight).
* NiceGuy:
** Clark Kent.
** Also Pete Ross.
** Jimmy starts off this way, until Davis Bloome enters the picture.
* NiceJobBreakingItHero:
--> [[spoiler: '''Fine/Brainiac''': You've opened the portal for Zod!]]
** At the end of "Onyx", [[spoiler:Lionel had originally started a charity after being given a second chance in life after getting out of prison, but one encounter with Lex's EvilTwin convinced him to go back to his old ways by the time the real Lex could reach him]].
** In "Descent" Clark breaks and enters into Lionel's office, tampering with evidence that could potentially link Lex.
* NinetiesAntiHero: ConversationalTroping in "Warrior":
--> '''Alec/Devilicus''': (''threatening to push Chloe off a building'') Lethal enforcers are way more interesting. They were big in the nineties.
* NoirEpisode: "[[Recap/SmallvilleS06E20Noir Noir]]''; black and white, period costumes, references to noir-era "Superman", a noir-ish storyline...
* NoMoreForMe: Perry White does this when the Kent family tractor plummets out of the clear blue sky to smash to pieces in front of him in "Perry".
* NoPlansNoPrototypeNoBackup: The designs for the Prometheus suit seemed to have only been written down on paper. So when Lana burned them there was no way to make another.
* NotHimself: Clark gets reprogrammed into Kal-El, complete with [[TheUnfettered full access to all his powers]] including flight; Lex, when he gets possessed by Zod; Lois when she is possessed by Faora in "Bloodline"; Lana when the Definitely Not Good Witch takes her over; countless other examples. In fact, Clark whenever he's infected by [[GRatedDrug Red Kryptonite]].
%%* NothingIsTheSameAnymore: "[[Recap/SmallvilleS05E01Arrival Arrival]]," "[[Recap/SmallvilleS06E22Phantom Phantom]]," "Arctic," "[[Recap/SmallvilleS08E07Identity Identity]]," "Requiem," "[[Recap/SmallvilleS09E01Savior Savior]]."
* NotQuiteFlight: Clark still can't fly. He can, however, leap tall buildings InASingleBound. [[MythologyGag Just like the Golden Age Superman.]]
* NotWhatItLooksLike: Smallville loves this trope:
** In "Rush", Clark and Chloe are making out in the Talon when Lana walks in on them. Clark is affected by red kryptonite and Chloe an adrenaline-inducing parasite.
--->'''Clark''': It's not what it looks like.
--->'''Chloe''': Yeah it is, Lana. It's exactly what it looks like.
** In "Gone", Martha Kent finds Clark and Lois in the bathroom together, Lois wearing Clark's shirt.
--->'''Lois''': I don't understand what the big deal is. We were just taking a shower—
--->'''Clark''': Showers, we were taking separate showers.
** In the episode "Crossfire", Oliver decides to help Mia and let her train at his home. His ex-girlfriend Lois visits just as Mia walks out of the shower.
** In the episode "Fierce", Clark offers to let Lana stay in his house and hopefully salvage their relationship.
--->'''Clark''': I have to warn you that my life has gotten a little more… [Kara walks into the room wearing a bikini] complicated.
--->'''Lana''': [gasps and looks at Clark worriedly] That might be an understatement.
--->'''Clark''': This is my ''cousin'', Kara.
** In "Escape", Lois caught Clark in the shower with a naked Chloe.
* NothingPersonal
-->'''Lana''': And then he had the nerve to say "It's nothing personal, only business."
* NowOrNeverKiss: It takes until the end of season 5 to get one with [[spoiler:Clark and Chloe]].
* TheNthDoctor: Morgan Edge played by Rutger Hauer and then Patrick Bergin, due to Hauer being unavailable; explained through [[MagicPlasticSurgery plastic surgery]]. [[JustifiedTrope Actually justified, given the fact that the character was on the run from Lionel.]]
%%* NurtureOverNature

[[folder: O to P]]
* ObfuscatingDisability: Lionel Luthor. In the beginning of Season 2, a life-saving surgery left him temporarily blind. [[ThrowingOffTheDisability He eventually regained his sight]], but neglected to mention it and faked being blind for a few more weeks because people let their guard down around someone they thought couldn't see. Street-wise Lucas Luthor, however, sees through the ruse immediately upon first meeting him; Lionel pours himself some water and doesn't put his finger inside the glass to know when it's full. Lucas tests his theory later by signing "BITE ME" on an important contract instead of his name, and when Lionel can't hide his reaction, Lucas forcibly throws a billiards ball at his head. Lionel reflexively dodges and is fully exposed.
* OffscreenMomentOfAwesome: In "Luthor," Tess and Lois somehow manage to stay alive against [[EvilTwin Earth-2 Clark]] until Oliver shows up with Kryptonite weapons, and even then, judging by the state of the three of them and the Watchtower, it must have been one hell of a fight. Arguably done on purpose to create a CrowningMomentOfFunny at the end, when Earth-1 Clark is transported back to Watchtower and is taken by surprise to see the place wrecked and Lois, Tess, and Ollie all aiming kryptonite arrows at him. Clark's facial expression says it all.
* OhCrap: Let's just say that whenever a hostile Kryptonian arrives, this is the default expression of [[MassOhCrap everyone]].
** [[spoiler:Earth2-Lionel's face says it all at the end of "Scion" when standing next to Lex's grave, he is surrounded by black smoke that transforms into Darkseid and towers over him. Oh crap, indeed.]]
** Lionel Luthor gets one in "Transference" as he sees Clark coming after him in the midst of a prison riot. [[spoiler: Even more so knowing that Lionel and Clark have switched bodies.]]
** An epic one from Zod at the end of "Salvation" when he realizes that he's just [[EngineeredPublicConfession accidentally confessed]] to killing [[spoiler: Faora]] in front of his troops and later when he realises that [[spoiler: Clark fatally stabbed himself with the blue kryptonite dagger, so nothing could prevent Zod from being transported to New Krypton to face ''[[FateWorseThanDeath justice]]'' from his former comrades]].
* OnceASeason: Starting off with SuperStrength, SuperSpeed and NighInvulnerability, Clark develops and eventually masters a new superpower once a season, although some seasons skip it, since they are running out of powers to showcase. The show's promise was that {{Flight}} would not come in until the end.
* OnePersonBirthdayParty: A flashback shows that as a kid, Lex Luthor had a birthday all alone. It gave context to his [[DarkAndTroubledPast miserable childhood]] and how he developed into the adult he eventually became.
* OpenSecret: While you can debate who and when, in some points before the move to Metropolis Clarks powers are used obviously enough that it seems to be implied that many people (those he saves especially) assume he's just a Meteor Freak who wants to keep his privacy, and so they leave him alone, despite knowing that he has powers. The fact that he's an alien, however, remains a secret.
* OrphanageOfFear: Where Granny Goodness is involved, there's always one involved and St Louise's Orphanage fits the bill.
* OurGhostsAreDifferent: "Tomb". [[spoiler:A bolt of lightning and a meteor rock bracelet raises one from a dead body that's implied to be ''in the Talon walls since before the series started.'']]
* OurVampiresAreDifferent: Kryptonite + bats + mutated rabies = fanged {{Psycho Lesbian}}s who like blood and [[HellBentForLeather black leather]] and have SuperStrength.
* OurZombiesAreDifferent: "Rabid", Type PF.
** Thanks to a serum derived from Clark's blood we get Type A ([[spoiler:Adam Knight and potentially several others.]])
** (''Smallville'''s [[OurMonstersAreDifferent everything is different]], really).
* ParentsForADay: Clark and Lana in "Ageless" with the odd twist that it only lasts a day because the child in question has a kryptonite-induced mutation that causes him to age by several years every few hours.
* PassingTheTorch: A heartwarming meta-example; Clark learns the whole truth about who he is from scientist Dr. Virgil Swann, played by none other than Christopher Reeve.
* PatrickStewartSpeech:
** For a while, ComicBook/{{Brainiac}} masqueraded as Clark's history professor (and another displaced Kryptonian). In ''Splinter'' he goes into a spiel in class about how humans have a long tradition of betraying one another (two examples given were Caesar and Brutus, and Jesus and Judas). Clark delivers a textbook Patrick Stewart Speech to Brainiac at the end of the episode.
--->'''Clark''': You don't know anything about this race. Yeah, they can be petty and dishonest and betray each other over nothing. But they can also be honest and loyal. And they would give up everything to protect someone they love... even if they were from another planet.\\
'''Professor Fine''': Kal-El...\\
'''Clark''': My name is Clark. And I'll always believe in my friends and my family.
** In ''Solitude'', the following episode, Fine betrays him but Chloe comes to his rescue.
--->'''Clark''': You know, Professor Fine said that human beings were insignificant and couldn't be depended on. He obviously don't know you very well.
** Clark spent a decent amount of time defending [[PlatonicLifePartners Chloe]] from superpowered beings. In "Kara":
--->'''[[Comicbook/{{Supergirl}} Kara]]''': [[PunyEarthlings She is just a human.]] (''[[ImStandingRightHere Chloe was standing right there]]'')\\
'''Clark''': [[TheSmartGirl A human who is smarter than both of us put together.]]
** ''Blue'', Kara tries to convince her father Zor-El not to destroy the human race, but he's completely unmoved and just beats her up and continues his rampage, forcing Clark to save the day. She surely learned quickly.
--->'''Kara''': I might have not been here long but I learned one thing: everything you told me about humans is wrong. They're good people and they're worth defending.
* PedestrianCrushesCar: A recurring bit when young Clark Kent saves a pedestrian from being hit by a car or bus, which crumples around Clark.
%%* PensieveFlashback: "Memoria," "Fracture," "[[Recap/SmallvilleS08E09Abyss Abyss]]."
* PersonalityPowers: Most of the Meteor Freaks get these.
* PhantomZone
* PhantomZonePicture
* PhlebotinumBattery: Clark is fighting against his Bizarro clone, who has all of his powers inverted. Kryptonite strengthens him and the sunlight weakens him; this is when Clark learns that the yellow sun fuels his powers. In an earlier episode, solar flares/sun spots cause his powers to go [[PowerIncontinence haywire]] and he doesn't have the same precision control.
* PlotParallel: Often between Clark and Lex, but sometimes played with. "Delete" does this with the introduction of Adam, who basically ''guilts'' Lana into backing off about his past, while at same time Chloe and Clark come to a mutual agreement about ''his'' secrets.
* PoliceAreUseless: Played with in Turbulence when Jimmy caught Davis killing someone in the hospital all of the lights are off, and people sleep through everything. It's quite literally impossible to get caught doing anything, and there are no security people anywhere. Yet later, Jimmy is getting ticked at Chloe for not believing in him or whatever shippy crap it was intimated to be, and he slightly raises his voice in anger, and some security guard comes up and says, "Sir, you're going to have to leave!"
* PoorlyDisguisedPilot: The "Comicbook/{{Aquaman}}" episode, although apparently not originally intended as such since it was going to be in a different continuity from the show.
* PowerCreepPowerSeep: Clark is suddenly powerful enough to shove a planet back into space in the finale, this was a planet capable of traveling under its own power too. This is more than a little out of synch with the power level he's shown to have during the rest of the series.
* PowerLossMakesYouStrong: As often as Clark loses his powers, this happens quite a bit, most notable being taking a bullet for Lois while weakened by kryptonite.
* PragmaticAdaptation: It takes elements from all versions of Superman from the Silver Age to Post-Crisis to The Superman Films and kind of puts it together while adapting it for a modern day audience.
* ProphecyPileup: Involving Clark, the Traveller, Naman, the destruction of Krypton...
* ProtagonistCenteredMorality:
** The heroes have balked at villains spying more than once (even legitimate government operations) and promptly headed back to their own watchtower full of spy equipment.
** Milder example in season one with Clark's telescope. Chloe likes to make fun of him for that.
** When Lana started the Isis Foundation she began experimenting on meteor freaks in the same way as Lex but while Lex’s action were treated as a MoralEventHorizon since she was searching for a cure it’s ultimately treated as a good thing. She once found a sick freak instead of calling a doctor or taking him to a hospital she locked him in a room and waited for him to die. This is treated as a noble gesture.
* PsychoExGirlfriend:
** Lex's girlfriend in season 2 has a psycho ex.
** [[spoiler:Alicia to Clark]] in "Obsession".
** [[spoiler:Lana to Lex]] after their messy break up sometime in season six.
* PsychoLesbian: Tina Greer.
* PubertySuperpower: XRayVision, heat vision and super hearing. His invulnerability and super speed also had notable increases. Most notably, Clark's heat vision starts kicking in as he gets, er, "excited."

[[folder: Q to R]]
* TheQuarterback: As Clark was the quarterback, the occasional episode has him dealing with the team. He is proficient enough to get a college scholarship offer, as well as translating some of Superman's bravado to leading in high school.
* RaceLift: Pete is white in the comics. The Martian Manhunter's "John Jones" identity is African-American on the show, but Caucasian in the comics. In an interview, Phil Morris (the actor who portrays Martian Manhunter) said that he once asked the producers if it was intentional that J'onn would take on the appearance of a racial minority as a reaction to the sensation of being an outcast since he's the only surviving member of his race. The producer's response was basically "[[AscendedFanon Not originally, but it is now.]]"
%%* RashomonStyle: "Suspect"
* RealityEnsues: Done cleverly with a HopeSpot. [[spoiler:After finding a photo that showed that Lionel's death was not suicide]], Lois and Jimmy are trapped by a shooter [[spoiler:under Lex's orders]]. The shooter shoots Lois in the shoulder after she locked them inside and went to attack.
* ReallyGetsAround: Oliver Queen is portrayed as being quite fond of female company. [[spoiler:He has slept with all three of the main female characters as of season nine.]] The Luthors are also all over this trope.
%%* RedemptionEqualsDeath%%
* RedemptionInTheRain: Of a kind, [[spoiler:in the episode "Rabid" when the people who have been turned into zombies, Lois included, are cured]].
* ResetButton: Used multiple times, but referenced by name in Season Eight's "Infamous".
* RestrainedRevenge: In "Action" after Lionel revealed that he was aware that it was Lana who kidnapped and tortured instead of doing something proportionate or even disproportionate as revenge he warned her that she was on a slippery slope.
* {{Retcon}}:
** The Veritas icon being retconned onto the Luthor mansion window.
** A very blatant and awkward one at the end of season eight. [[spoiler:This Jimmy Olsen turns out to be the older brother of ''the'' Jimmy Olsen. Named Henry James Olsen, while his younger brother is the James Bartholomew Olsen from the comics.]] That being said, the showrunners did make it up to [[spoiler: Aaron Ashmore by having him return as Jimmy--this time the real one--in the DistantFinale]]. Although, the writers knew from the start of Jimmy's run that [[spoiler:he would not be the real Jimmy Olsen.]] Although this was more down to ExecutiveMeddling than anything. They decided that either when Smallville ends, or they had "taken Jimmy as far as he could go" they would reveal the truth.
** In Season 10, Tess is revealed as Lionel's illegitimate daughter and Lex's half sister. This is despite several Season 8 episodes implying that Lex and Tess had a romantic involvement, such as in "Bulletproof" where she admits to having loved him. However, Tess definitely doesn't know she is his half sister and no one really knows what is going on in Lex's head.
* {{Retool}}: The series' creators left before Season Eight began, and the show has shifted focus with far greater ties to pre-existing DC characters. Only two original cast members remained (Clark and Chloe), and Oliver was added to the main cast. Chloe (Allison Mack) only came back for a few episodes in Season 10. Lionel Luthor (John Glover) returned for the rest of the series, albeit [[spoiler:he is not the "original" Lionel Luthor but from a parallel universe]].
* ReunionRevenge: Linda Lake in "Infamous".
* ReusableLighterToss: In season 3 episode "Slumber" (averted), and same season "Hereafter" (played straight)
* RevivalLoophole: Tess is being pursued by Checkmate, who implanted her with a tracking device powered by her body. Chloe stops her heart with a defibrillator to deactivate the device and (eventually) injects her with something to start it again.
* RewatchBonus: In "Splinter" when Clark starts driving home his seatbelt suddenly disappears.
* RousseauWasRight: Both Martha Kent and Lex Luthor's clone espouse the idea that people are taught to hate and that Clark is so noble because nobody ever taught him that.
* RunningGag: Lois' very [[TheEighties Eighties]]-Hair-Band taste in music. Also her poor spelling, which started way back in the ''movie'' (admittedly, it was incorporated as canon in the comic, even before the series started). Whitney's inability to drive a truck without totaling it. Clark and Chloe's ship-tease moments. People inadvertently exposing Clark to kryptonite (Andrea's locket, Lex, Bart and Chloe have all opened the lead box with the meteor rock in it, Lana's necklace, etc.) Also, Lex gets pistol whipped a surprising amount.

[[folder: S to T]]
* SadisticChoice: [[spoiler: Checkmate tries to force Clark to serve them by showing a TV screen with a guy pointing a gun at Chloe's head. Fortunately, when the gunman talks, [[TakeAThirdOption Clark hears him, allowing him to locate them and save her]].]] [[spoiler: Done again in "Lazarus" which is a MythologyGag to the first Superman movie, as Lex says "you can't save them both."]]
** Done again and again and again, just look at the Quotes sub-page on the trope page.
* SanitySlippage: As Lex's paranoia, selfishness, and NeverMyFault complex take over his personality, he arguably experiences this.
* SarcasticClapping: Jonathan does this in "Jitters" after Clark tries and fails to clean up after a WildTeenParty before his parents get home.
* SarcasticConfession: Clark, asked how he knew which cabinet to look in to find a dead body: "Because I can see right through the door, Pete."
* SchoolNewspaperNewshound: Chloe. In the early seasons, she is seen putting out a new, full edition of the Smallville High Torch ''every week'', which is pretty remarkable for a high school newspaper.
* SealedCastInAMultipack: The HalfArcSeason for season 6 was assorted Kryptonian baddies being accidentally released from the PhantomZone and Clark having to round them up.
* SealedEvilInACan: In the fifth season, Brainiac's primary goal is to release Zod from the Phantom Zone. He eventually succeeds in the season finale and Zod's first action upon being freed is to [[SealedGoodInACan put Clark Kent into the same can that he just escaped from]]. Clark manages to escape on his own, without help from the outside, and subsequently reimprisons Zod in the season six premiere. He then spends the rest of season six hunting down the other Phantom Zone prisoners who escaped at the same time he did one by one and either killing or preferably reimprisoning them.
* SecondSuperIdentity: Clark Kent/Superman takes on a secondary superhero persona as "The Blur", when Jimmy Olsen captures him on camera as a red-blue blur.
* SecretKeeper: There's no main character on the show who's ''not'' one. Lois was the last one who didn't know Clark's secret (a fact not lost on her in ''Lazarus''). It's implied that [[spoiler:Sam Lane figured out Clark's secret at the end of "Ambush", which has been suggested in #3 of the ''Smallville Season 11'' comic book]].
** Lex's knowledge of the secret and his other memories was removed by a neurotoxin used by Tess in the Finale.
** Most of the people who have learned Clark's secret are dead, their memories wiped, or incommunicado (in the Phantom Zone, inside some super science device, in a coma etc). Some good "Meteor Freaks" have learned and kept the secret.
** Lex sorta but not quite figured it out early on, but Clark refused to fully entrust him with it. Up until season 7, he's constantly finding some strong evidence but gets rejected or disproved by either Clark temporarily being BroughtDownToNormal, or as in ''Justice'', Lionel covering for him. Every time Lex 'finds out' he'll always state proudly 'I knew you were different, Clark', [[EasyAmnesia only to have his memory of the event removed.]]
** Tess figures it out by reading Lionel's journal, and spends a season not-so-subtly telling Clark she knows and wants him to trust her, but Clark refuses. [[spoiler: He finally caves, while confronting her and holding her up by her throat.]]
* SelfDisposingVillain
* SelfDuplication:
** Brainiac, being as he was a Terminator 2-like living liquid metal produced by a spaceship, could do this [[SuperpowerLottery on top of so many other things.]] Mostly used so he could be in several places at once to throw people off his scent while plotting.
** A season two MonsterOfTheWeek, Ian Randall, was much more limited: one extra person would climb out of his back and he used one to study [[MesACrowd in two places at once so he could achieve the best grades]] since when they recombined, so would their memories.
* SelfMadeOrphan:
** [[spoiler:ComicBook/LexLuthor murders his ArchnemesisDad Lionel as his [[MoralEventHorizon final step]] into true villainy. Lionel himself was revealed to be one of these earlier in series, having had his friend Morgan Edge kill his [[TheAlcoholic Alcoholic]] AbusiveParents in a gas fire. One can only wonder what Lex's children will do, should he have any...]]
** [[spoiler:Technically Tess kills Lionel as well, though it's his AlternateUniverse counterpart. Regardless, he is still considered her father even by Tess herself, and she kills him [[OffingTheOffspring in self defense]].]]
* SeriousBusiness: In "Drone," one of Clark's classmates uses her GreenRocks powers to assassinate her rivals for the post of StudentCouncilPresident, because she's convinced herself that the course of her entire adult life rides on the outcome.
%%* SexDressed%%
* SexIsEvil: See "Bound".
* SheIsNotMyGirlfriend:
** Although the specific phrase is never used, Clark said something to this effect about Lois all the time from Seasons 4 through 7. However in Season 8, he starts to reevaluate his feelings on that matter...
** Clark and Chloe, every now and then. Davis once mistook her as his [[spoiler:fiancée when he sees her engagement ring from Jimmy.]]
* ShipSinking:
** Lana's storyline during her return in Season 8, though not until her last episode ([[spoiler:"Requiem"]]). [[spoiler:Clark can never go near Lana again because the suit that is grafted to her skin is irreversibly contaminated with massive amounts of Kryptonite.]]
** The writers have gone to great lengths to explain to fans that Clark and Chloe will never be anything more than friends, pointing out that Clark doesn't reciprocate her feelings, and that Chloe herself eventually gets over it.
* ShipperOnDeck: Lex for Clark/Lana early in the show. He continually tells Lana that she's with the wrong guy and sets Clark up with her on several occasions.
** Ironically, Lex would later marry Lana and it would be a large factor in the break up of Lex and Clark's friendship in addition to Lex's evil deeds. In addition, a few years after Lana and Lex divorce, Lex finds a way to prevent Clark and Lana from ever being together again.
** Lois is encouraging towards Chloe's affection towards Clark in the middle seasons.
** In a reversal, after [[spoiler:Lois accidentally and unknowingly kisses Clark and says he's a better kisser than her current boyfriend Oliver]], the look of utter glee on Chloe's face can't be mistaken as anything but this.
* ShootingSuperman: The most idiotic example of this happening is in "Infamous". After being accused of Lex's murder in an alternate timeline where he revealed his powers, a SWAT team attempt to shoot Clark. Despite knowing that he is ''bulletproof''.
* ShopClass: Brainy kid Ian Randall couldn't get anything better than a '''C''' in that class and [[DisproportionateRetribution killed the teacher]] to cover it up.
* ShotToTheHeart: Clark does this to Chloe in "Truth" and Lana in "Thirst". Chloe does it to Tess in Season 9.
* ShoutOut:
** Jonathan Kent (played by John Schneider) is heard playing the theme to ''Series/TheDukesOfHazzard'' in his car. In one episode, Tom Wopat (who played the other Duke cousin) shows up as an old friend of Jonathan. Thanks to a stuck door Jack (Wopat) has to get in his car (a [[CoolCar Dodge Charger]]!) through the window.
** Chloe and Lois get a few per episode. There is also an occasional shout out to Clark's later career and eventual marriage.
** In season 3, Clark [[spoiler:hopped up on red Kryptonite]] has a FunTShirt that has the symbol of Series/TheGreatestAmericanHero.
** In an episode where Lana joins a sorority of krypto-made vampires, Clark and Professor Fine (Creator/JamesMarsters) have this exchange:
---> '''Clark''': This is gonna sound crazy, but she was bitten by.. a vampire.
---> '''Prof. Fine''': There's no such thing as vampires.
*** The lead vampire in that episode is a blonde valley-girl named Buffy Saunders, a reference to [[Series/BuffyTheVampireSlayer Buffy Summers]].
** Also from the above ep, Milton Fine claims that Luthorcorp is working on a Project [[{{Film/THX1138}} 1138]].
** The constant usage of PersonAsVerb, usually from Chloe.
** The origin of Greg Arkin is an intentional dark echo of Franchise/SpiderMan.
** Lex says that the process to turn Victor Stone into Cyborg cost "[[Series/TheSixMillionDollarMan a lot steeper than six million dollars".]]
** Season 5 has a VillainOfTheWeek PlayingWithSyringes [[Film/ReAnimator and a glowing serum that brings people back from the dead.]]
** All of "Mercy" to ''{{Franchise/Saw}}''.
** Crossing over with ActorAllusion, Michael Shanks' Hawkman wryly remarks that he's 'an expert at dying'. Shanks' previous (and most famous) role was as Doctor Daniel Jackson in the ''Franchise/StargateVerse'', put ComicBook/JeanGrey to shame, dying a grand total of ''12'' times in 10 seasons, not counting the four times he was mistaken for dead and various robots and virtual reality counterparts.
** In the Season 10 episode "Harvest", when Clark rescues Lois from being sacrificed by a village of religious zealots, Lois tells the village that Clark was sent by God to punish them, [[Film/PulpFiction "With great vengeance and furious anger"]]
** Cross DC/Marvel examples include:
*** Season 5 has a hitman called [[Franchise/SpiderMan The Chameleon]], [[spoiler:but with invisibility instead of disguises.]] Worth noting is that he's able to carry on committing evil after Clark saves him from a car crash, which sounds like a rip on the traditional Spider-Man origin story.
*** In a season 9 episode, when Chloe and Clark are [[spoiler: searching for Ollie after he'd been kidnapped,]] they use a computer generated map of the world that shows where all the [[spoiler: Kandorians]] are and in the process, ending up looking like a suspiciously similar version of [[ComicBook/XMen Cerebro.]]
*** In Season ten, to calm people's mistrust of superheroes, [[spoiler: Oliver unmasks himself, [[Film/IronMan by calling a press conference, announcing that 'I am [hero identity], as an ex girlfriend who's a reporter watches on, resulting in the crowd of reporters suddenly getting louder and ask a ton of questions]]]].
* ShowDontTell: A lot of {{Informed Attribute}}s and CharacterShilling for Lana.
* SignOfTheApocalypse: Clark Kent and Karaoke.
* SkewedPriorities: In "Requiem" instead of trying to find the bomb Clark decided it was more important to find Lex. Even Chloe called him out on this.
* SkywardScream: Lex at the end of "Persona".
* SlapSlapKiss:
** Jimmy and Chloe indulge in this from time to time. Often due to TheMasqueradeWillKillYourDatingLife on Chloe's part. Or mutual flirting between [[Comicbook/{{Supergirl}} Kara]] and Jimmy. Or Jimmy having an inferiority complex towards Clark, who Chloe is fiercely loyal to. They really do have quite a few issues.
** A more violent version in season nine, shown in ''Escape''. [[spoiler:Tess and Zod had a passionate kiss after Tess shoots at Zod, who returns a NeckLift only to be subdued with kryptonite.]]
** In Season 8 episode "Committed" when Oliver and Tess are fighting with sticks before their date, they wind up kissing each other.
* TheSmurfettePrinciple: The earliest version of the Justice League includes [[Franchise/{{Superman}} Clark]], ComicBook/{{Aquaman}}[=/=]Author, Cyborg/Victor, [[Franchise/TheFlash Impulse]]/Bart, ComicBook/GreenArrow[=/=]Oliver, and Chloe. This defies some common expectations however, as she is {{The Smart G|uy}}irl and is, at that time, romantically involved with someone outside the group.
* SomethingElseAlsoRises: In "Crush," when Chloe makes out with a telekinetic, all of the small, heft-able objects in the room float up into the air.
* SoulJar: Jor-El's recorded mind in the Fortress computer (sort of); the Phantoms.
* SpiritualSuccessor: To ''Series/BuffyTheVampireSlayer'', due to the fact that both combine teen drama with the superhero genre. Both series have similar CharacterDevelopment and even episodes.
** In turn, ''Smallville'' was succeeded by ''Series/{{Arrow}}'', another reimagining of the DC mythos and the flagship DC show of WB/The CW.
* SpotTheImpostor:
** Happens several times; Clark and [[ShapeShifting Tina posing as Clark]], Clark and Bizzaro, for example.
** An averted example appears in the episode "Onyx"; Lex has inadvertently (and at first unknowingly) created an evil clone of himself (Black Kryptonite separated the Good and Evil personas of him). In order to be sure he's talking to the real Lex, Clark asks about the Lex he's talking to (the evil one) about an encounter he knows he had with the real Lex. Little does Clark know however, the evil version was listening in on the conversation, and manages to fool Clark at first.
* StalkerWithACrush: Too many to count.
** Including, going by the Season 1 DVD commentary, the show's creators. It's kind of creepy the way they ''gush'' over then-teenage Lana/Kristin, calling her "[[CreatorsPet the true magic of the show]]."
** Lana isn't the only one who gets them. Clark had Alicia stalking him, and Maxima even traveled to Earth from Almerac just to hunt him down to be her mate.
* TheStarscream: Some fans accuse Oliver of wanting to "steal" the position of leader from Clark, and lambaste him for [[FelonyMisdemeanor daring to question Clark's decisions]]...even though Oliver has technically been the leader of the superhero community from the very beginning of it's collaboration, and in fact is the one who actually put the community together in the first place (Clark is TheHeart, but he arguably doesn't become the undisputed leader until Season 10).
* StarterMarriage: [[spoiler:Jimmy and Chloe]]. They were very sweet together at first but gets increasingly rocky due to the involvement of first Clark, then Davis. Ends with a huge TearJerker when [[spoiler:Jimmy [[BreakTheCutie shouts at Chloe and declares marrying her is the biggest mistake of his life]]]].
* StartMyOwn: Lex's response to Lionel hindering his progress at [=LuthorCorp=] was starting Lexcorp.
%%* StartOfDarkness: "Commencement" (for Lex), "Lexmas" (for Lex, again), "[[Recap/SmallvilleS09E07Kandor Kandor]]" (for [[spoiler:Zod]]).
* StealthHiBye:
** Clark's favorite way to enter or exit any scene. Usually the special effects crew are kind enough to at least give us his distinctive superspeed whoosh sound, but occasionally not, such as in "Splinter" where Clark has been infected with silver kryptonite (which gives him paranoia and hallucinations) and breaks into Lex's castle. Lex walks down a darkened hallway, looking everywhere for Clark, and when he turns around, Clark is standing where he'd just looked with no apparent way of entering the room.
** [[Comicbook/{{Supergirl}} Kara]] picked up the family business and arguably did a better job (read:more off-screen Stealth Byes due to budget cuts).
** Blink and you'll miss it, but in an episode where Clark is depowered ([[spoiler:actually inside a virtual world]]), he leaves the room without Lois or anyone else present noticing his disappearance for a few minutes, showing that he can actually do this without using super speed.
* StockEpisodeTitles: Lots. From least to most common on the list: "Vortex", "Red", "Salvation", "Odyssey", "Zero", "Apocalypse", "Phantom", "Blue", "Truth" ("The Truth" on the list) "Forever", "Sleeper", "Prey", "Lockdown", "Whisper", "Descent", "Abandoned", "Doomsday", "Shattered", "Quest" ("The Quest" on the list), "Crossfire", "Asylum", "Suspect", "Metamorphosis", "Exodus", "Prodigal" ("Prodigal Son"/"Prodigy" on the list; the episode ''is'' about a wayward son), "Conspiracy", "Nemisis", "Fever", "Cure" ("The Cure" on the list) "Power", "Bloodline" ("Bloodlines" in the list), "Phoenix", "Justice", "Fallout", "Reckoning", "Vengeance", "Requiem", "Sacrifice", "Checkmate", "Obsession", "Resurrection", "Crush", "Masquerade", "Arrival", "Escape", "Hero", "Witness", "Legacy", "Homecoming", "Reunion" and the obligatory "Finale", many of which are rather…literal. With over 50 such episodes, there are over 1 in 5 episodes which have stock names. There are also "Identity" and "Crisis" which makes up "Identity Crisis" from the list.
%%* StoryArc%%
* StrangeMindsThinkAlike: Both Lex and Lana tried to get Clark to reveal his secrets when he lost his memory in "Blank". While Lex succeeded Clark regained his memory before Lana could.
* StrawCharacter: Cat Grant, a major departure from the freewheeling comic book version. When Lois is performing rituals under possession of Isis, Cat actually says "I will never understand liberals." Gordon Godfrey is a caricature of conservative talk show hosts, though that at least is true to his comic book roots. Although in "Icarus", [[spoiler:Cat [[CharacterDevelopment agreed to at least be more objective when it comes to superheroes]]]].
* StrawFan: Ben Meyers in "Action" is essentially a proxy of overzealous fanboys who threaten actors and crew members when movies or TV shows make changes to the source material.
* StuffBlowingUp: The show probably has the most serious usage of StuffBlowingUp then anything. Sometimes it is difficult to find an episode ''without'' an epic explosion. Just in season one, we have a classroom combustion ("[[PlayingWithFire Hothead]]"), greenhouse explosion ("Craving"), car explosion ("Metamorphosis"), bus near-explosion ("Rogue"), gas canister explosion ("Drone") and a gas-line explosion ("Obscura").
* StupidGood: In "Hero", Chloe threatened Lex the owner of the Daily Planet with an expose in the Daily Planet. This seems to be a regular occurrence; the heroes regularly use InsaneTrollLogic to accuse the villain of something and are only justified because the villain later uses it for evil ends.
* StupidEvil: Red kryptonite turns Clark into this.
* {{Sufficiently Advanced Alien}}s: Kryptonian [[PowerCrystal crystalline]] technology borders on the magical.
* SugarAndIcePersonality: Dr. Emil Hamilton.
* {{Superhero}}
* SupernaturalSoapOpera
* SupernormalBindings: Handcuffs with kryptonite in them which are used to restrain Kara.
* SuperSenses: Take your pick.
* SuperWeight:
** Type 0: Lois, Chloe, The Kents, Lex, Lionel, Tess, Lana [[spoiler:before she gains Lex's super suit]]
** Type 1: Green Arrow, Rick Flag, Deadshot, Slade Wilson,[[spoiler: or is he?]]
** Type 2: Most meteor freaks/metahumans, Impulse, Aquaman, Cyborg, Black Canary, Hawkman, Stargirl
** Type 3: Most aliens, Kryptonians under the yellow sun, Clark, Kara, Martian Manhunter, Zatanna, [[spoiler:Lana after gaining Lex's super suit]], Zod, Brainiac, Doomsday, Darkseid
** Type 4: Doctor Fate
* TakeThat:
** The episode "Hex" in Season 8 was meant as a spoof of the infamous Chlois Theory. For those unfamiliar with it, the Chlois Theory was basically an idea created by some Chloe/Clark shippers and hardcore Chloe fans who wanted Chloe Sullivan to "become" Lois Lane, stating that at some point, she would assume this identity. Oddly enough, the theory didn't die when the actual Lois Lane was ''brought into the show in Season 4''. Many Chlois theorists were rather aggressive in their hatred for the Lois Lane character when she was introduced, and there were massive {{Flame War}}s between fans of Erica Durance's Lois and the Chlois theorists who still clung to the idea that Chloe would one day "replace" Erica Durance's character as the one true "iconic Lois Lane" (a phrase thrown around a lot during these debates). This occurred ''despite'' the fact that the show's creators, producers, and actors all repeatedly stated that the Chlois theory would ''not'' come true. One can only imagine that the showrunners finally got fed up and decided to write this episode to spoof it. To make the point more obvious, after spending a day as a duplicate of Lois Lane, Chloe (after being restored to her usual self) says aloud that she will never be Lois Lane, and finally chooses a new career path: working for the Justice League full-time, declaring "Watchtower (her codename) is officially online."
** The Vigilante Registration Act, headed by one General Slade Wilson, is a subtle one aimed at Marvel's ''Comicbook/CivilWar'' and ''Comicbook/DarkReign'' storylines. The VRA is less of a take that and more of a Homage.
* SwissCheeseSecurity: Lex Luthor used to be the {{Trope Namer|s}}.
* TapOnTheHead: Clark has been known to employ this rather literally, on occasion. The first such example is in "Nicodemus" when he lightly tapped Pete on the forehead and knocks him cold. Other characters also sometimes employ this trope in the traditional manner of smashing objects over someone's head. Note that since Clark has [[NotTheFallThatKillsYou caught people and objects without any damage to the person or obstacle even if they were moving/falling at a very high velocity]], it makes "sense" that his taps on the head would not have the same damage that smashing an object over someone's head would.
* TattooedCrook: In "Kinetic," Smallville is terrorized by a gang of burglars who can phase through walls because of their kryptonite-ink tattoos.
* {{Technobabble}}: Any effort (particularly by Chloe) to give a scientific explanation for how a superpower works.
* {{Telepathy}}: "[[Recap/SmallvilleS01E16Stray Stray]]," "Ryan"; Season 9's "[[Recap/SmallvilleS09E04Echo Echo]]" centers around Clark gaining this as a temporary ability courtesy of Jor-El.
* TellMeAboutMyFather: Clark asks The Fortress AI (a recording of Dear Old Dad), Comicbook/{{Brainiac}}, Raya, and Comicbook/{{Supergirl}} about his parents, but mainly Jor-El. He also gets to interact with a simulation of his mom Lara (played by Helen Slater, who played Supergirl in the 1984 film ''Film/{{Supergirl}}'').
* TemporaryLoveInterest:
** 1: Kyla Willowbrook, a Native American who can shapeshift. When she found out the truth of his nature, her attraction to him peaked and they began an instant romantic relationship with their first kiss; died in one episode
** 2: Alicia Baker, a superpowered girl whom Clark dated between Lana and Lois; think Lori Lemaris from the Silver Age, only evil. Went Fatal Attraction and imprisoned and then brought back reformed 1 season later; died in two episodes.
** 3: Jessica "Jessie" Brooks, a new student at Smallville High School who dressed provocatively and liked to party, so consequently, she got along well with Clark Kent when he was affected by Red kryptonite. Jessie and Clark dated briefly. Clark told Lex that Jessie was his new girl. By the end of the episode she and her father were on the run.
* ThatCameOutWrong: In "Crusade", Lois meets Martha after finding Clark in the field, amnesiac and naked:
-->'''Lois:''' Guess I'm a sucker for stray dogs and naked guys. (beat after seeing Martha's expression) Okay, [[LampshadeHanging that didn't come out right]].
* ThemedAliases: The Flash is a punk kid possibly named Bart Allen who has a bunch of different [=IDs=] which have different names of the Comic Book versions of the Flash: Jay Garrick, Barry Allen, and Wally West. In "Absolute Justice", [[CelebrityParadox Jay Garrick is confirmed as existing as the original Flash.]]
* ThemeMusicWithholding: John Williams' Superman Theme plays in the final scene of the final episode.
%%* ThereIsAnother: "[[Recap/SmallvilleS02E18Visitor Visitor]]" [[spoiler:subverts this eventually]].
* TheyKilledKennyAgain: [[spoiler:In a dramatic use of the trope, Clark's fathers, or [[ParentalSubstitute anyone who treats Clark as a father would]], all end up dead, usually protecting him. Before the series starts, Jor-El died on Krypton to save him. Come Season 5, Jonathan dies after succumbing to his heart problems, which came about from him getting the power to save Clark in Season 3. Following this, off-screen at some point before Season 6, Virgil Swann is dead. Lionel, who is subsequently an avatar of Jor-El, is killed in Season 7 by Lex while covering up Clark's secret. Then in Season 9, the Kandorian clone of Jor-El is killed by another Kandorian. Plus, if the voice in the Fortress counts, the many times it's shut off, destroyed, taken over, or apparently destroyed pushes this number up quite a bit more.]]
* ThreeAmigos: Clark, Pete, and Chloe in the early seasons.
%%* TimeTravel: "Reckoning," "Apocalypse," "[[Recap/SmallvilleS08E11Legion Legion]]," "Infamous," "Pandora."
* TokenMinority: No, not the Kryptonian, smart-ass.
* TooDumbToLive: Basically everyone at one point or another, but especially Comicbook/LanaLang. (Honestly; going swimming, after dark, in the school pool, in Smallville?) One of Robert Anson Heinlein's sayings by way of his longest-lived character fits her perfectly: "Live and Learn. Or you won't live long." (The interested can look it up in ''The Notebooks of Lazarus Long''.
** In "Onyx" Clark fully aware of exactly what Lex regularly experiments on decides to follow Lex to his latest experiment.
* TookALevelInBadass: The premise of the whole series is Clark going from mild-mannered farmboy to the world's greatest hero. Arguably Clark's greatest leveling took place between Seasons Eight and Nine, as evidenced by his ability to take on trained [[spoiler: Kryptonian]] soldiers without his powers during Season Nine. He fares better in his first fight than his last, but he "won" both of them.
* TornadoMove: In "Homecoming", [[spoiler:future Superman puts out a nuclear plant fire by flying around it really fast]].
* TrappedInASinkingCar: Kicks off the plot in the first episode. Lex Luthor isn't watching as he's driving and runs Clark over, shooting off a bridge and into the lake. Clark rips the roof off of Lex's car to rescue him. Much of the rest of the series has a subplot of Lex trying to figure out how Clark did that.
* TrashTheSet: Halfway through the final season, Luthor mansion (which had been a feature of the show since episode 1) is burned to the ground by [[CloningBlues Alexander Luthor]]. And earlier in the season, the Talon coffee shop/upstairs apartment is blown up by a missile launched by the Comicbook/SuicideSquad.
* TraumaticHaircut: Lionel, in the Season 3 finale.
* TraumaCongaLine: Chloe, Chloe, oh dear god Chloe. She may cross to an IronWoobie but good god, the stuff that happens to her, it's amazing she didn't snap.
%%* TrialBalloonQuestion: "Visitor"
* TropeTrigger: Several episodes required Clark Kent to become BrainwashedAndCrazy. The writers handled this by retooling red kryptonite from the Superman canon, so that instead of having some bizarre random effect on Clark it always turned him into a sociopath. It got so whenever fans saw a red [[GreenRocks glowing rock]] they knew what trope would be in force for the episode.
* TuckAndCover: Clark's default mode of rescue, mostly when it comes to explosions. First example was in the second episode, "Metamorphosis".

[[folder: U to V]]
* UltimateUniverse: Essentially this, being a re-interpretation of the Superman mythos. Not to mention that there are some DC Comics characters making guest appearances, sometimes heavily modified.
* UnConfession: Used several times throughout the series. The eighth season alone features Lois 'admitting' to [[spoiler:being in love with Clark]] under lie detector and then claiming to have fooled the machine, and (in a separate episode) Clark [[spoiler:revealing his identity to the world]]. In a past episode, Clark also told Lana the truth about him before resetting time after she died, and, in a strange inversion, he once [[LaserGuidedAmnesia erased the knowledge of his alien heritage from Chloe's mind]] -- which ''also'' didn't stick (i.e. she remembered).
* UnclePennybags: Clark and his friends benefited vastly from a series of sugar daddies. First, from Seasons 1-4, ComicBook/LexLuthor often bailed Clark & friends out of their money troubles, as he was still essentially [[LonelyRichKid trying to buy Clark's friendship.]] After Lex gets caught using armed and superpowered thugs to hold Clark's parents hostage (and thus force him to reveal his secret if it had gone as he'd planned) in Season 5, Clark distances himself from Lex. However, for most of Season 5, Lionel steps in and starts eagerly playing the role of UnclePennybags in a desperate attempt to impress Martha with his generosity. Lex occasionally still chips in money, but only in odd circumstances when he and Clark are thrown into a position where their interests coincide. Then from Season 6 onwards till the end, [[ComicBook/GreenArrow Oliver Queen]] steps in as Team Clark's big financier, as he is the major backer of the Franchise/{{Justice League|OfAmerica}}, eventually being joined in this role by former DarkActionGirl Tess Mercer in the later seasons.
* TheUnfairSex: Lana’s great aunt is portrayed very sympathetically even though she cheated on her husband with a man she just met and admitted she never loved him. To make matters worse Dexter blamed himself for not letting her go and him spending the rest of his life in jail after being framed for her murder was just punishment. It runs in the family Lana repeatedly falls in love while she’s dating someone else. Yet the fact that Lex likes to sleep around makes him a horrible person who treats woman like crap. This is especially jarring when you remember that in every committed relationship Lex has had before that episode the woman betrayed him. So it is very understandable why he would prefer meaningless flings. The woman who tried to kill him cheated on her fiancée. The only one to blame for her ruined relationship was her.
* UnfinishedBusiness: Chloe is possessed by the ghost of a girl to find and take revenge on her murderer.
* UngratefulBastard:
** Clark saves Lana's life on a weekly basis, but she continually acts as if he's this horrible person who can't be trusted, just because he likes his privacy.
** Lionel Luthor, as revealed in the Season 2 episode ''Lineage''. It turns out that Jonathan helped save Lex's life in the aftermath of the meteor shower. Lionel says if there's anything he can do for Jonathan, to let him know. He calls this favor in to ask for help faking Clark's adoption papers (since they couldn't just say he fell out of the sky in a spaceship), and Lional complies. But then he proceeds to use this favor as an opportunity to ''blackmail'' Jonathan into convincing the Ross brothers to sell their creamed corn factory to him.
* UnwantedHarem: Several. Lana used to get a StalkerWithACrush on an almost-weekly basis in the earliest seasons. Clark himself has had a few. Alicia started out as a welcome suitor, who quickly became unwanted when she turned into a StalkerWithACrush. Maxima from Season 8 would definitely count as one too. Chloe in the first few seasons also had a huge crush on Clark, but this apparently faded.
%%* UtopiaJustifiesTheMeans: "Pandora"
* VaguenessIsComing: Jor-El's warning about Darkseid's coming is so pointlessly vague that Clark actually thinks he's talking about something else and ends up doing nothing to stop him.
* VanHelsingHateCrimes:
** Happens a ''lot'' to Meteor-Freaks, who are routinely experimented on.
** The Kandorians perform this on ''Humans'' in Season 9. With the added hypocrisy to then beg for ''mercy'' from a former test subject who decided to return the favour in kind.
* VehicleVanish: In a Season 9 episode, Major Zod realizes that Tess has played him. He looks across the street, and sees Tess raising her coffee cup in a sarcastic salute to him. A truck passes and in that split second, Tess is somehow gone. Unless she managed to make a highly-improbable jump onto the side of the truck and ride away with it, one wonders exactly how Tess did this, considering the fact that she has no superpowers.
* VerySpecialEpisode: Any episode with Dr. Swann ended with a PSA about donating to the Creator/ChristopherReeve Paralysis Foundation.
* VictimOfTheWeek: Played with at times by crossing with MonsterOfTheWeek. Also played straight, of course.
** "Lexmas" has Clark coming across a suicidal binge-drinking "Santa", and helps him straighten out his life [[spoiler:by catching him when he does fall from the top floor, and then roping him in to help out Chloe.]]
* VillainBall:
** In "Sneeze", Lex threatens to test the Super Soldier Serum on Lana. So yeah, you give your hostage a serum that turns them into a super-fast God that can overpower you, and trust they won't do it because you're pointing a gun at their lover. Powers that can, to quote the guy administering the serum, make you swat away bullets like bugs.
** In "Bound", despite the fact that she has Lex tied to a chair, he knows who she is, and she's got her vengeance in hand, instead of killing him with the gun she had, the killer decides to kill him by lighting brandy on fire.
* VillainHasAPoint:
** In "Descent" Lex blames Clark for stressing Jonathan into death after the later says that Lex could have had his father's approval if he'd only tried. However Clark was warned that saving Lana would have consequences, and he chose to, leading to the death of his own father. Meaning that Lex was absolutely right.
*** And Lex did try to gain his father's approval. How was it met?
*** Although I admit that this might not be valid, Jonathan died from a heart attack, due to overexerting himself while fighting Lionel Luthor and stress like Lex said, but the main cause was because of his health issues. In Season 3, when Jonathan made a deal with Jor-El to gain powers in order to bring back Clark from Metropolis when he (Clark) was on Red Kryptonite, the experience started to ruin his health due to ocerexertion of his body. So if Clark hadn't used the Red Kryptonite, then Jonathan would never have had to make a deal with Jor-El and gotten the health problems that were the main cause of his death along with the stress like Lex said. So Lex is completely right that Clark caused Jonathan's death.
** Due to the Anvilicious overuse of HumansAreTheRealMonsters to the point where nearly a single episode can’t go by without a single character even the title character themselves mentioning how flawed humans are. So it is perfectly understandable why the Human Supremacist Movement wouldn’t want their planet to be overrun with god-like beings of similar mentalities.
* VillainTeamUp: "Asylum." Two meteor freaks, Eric Summers and Ian Randall, get assistance from [[TheHunter Van McNulty]] because he knows Clark's weakness. They plan to escape from Belle Reve by having Eric take Clark's powers. [[spoiler:Leads to ChronicBackstabbingDisorder.]]
* VisionsOfAnotherSelf: Done a few times in order to explore otherwise forbidden character pairings.

[[folder: W to X]]
* WeirdnessCensor: The people of Smallville seem to have a pretty strong one. In one episode, Chloe is suspended from the school paper for writing about meteor freaks...by the same principal who, a few episodes before, was set on fire by a pyrokinetic (who later immolated himself in the football team's locker room without anyone finding anything amiss about the circumstances).
* WeirdnessMagnet: How else would one describe the town of Smallville, Kansas? And Clark himself.
* WellDoneSonGuy: Lex Luthor. ''Dear God'' Lex Luthor. Results in a TearJerker when Chloe--who received TemporaryPowers to compel everyone around her to tell the unfiltered truth--questions Lex about why he can't just walk away from Lionel after all he's done to him, and Lex replies "Because he has the one thing that I want...I want him to love me." As if that wasn't enough, it results in an even ''bigger'' TearJerker at the end of the episode when an annoyed Lionel hatefully sneers that Lex is really starting to annoy him and demands to know "What do you want from me?!" and a dejected Lex quietly replies "It doesn't matter, Dad. Because [[TheWoobie I'm never going to get it]]." It gets to the point that, for the first couple of seasons, he was even trying to get a "Well done, son" from Clark's father. He ain't picky.
** Lex actually ''does'' get a minor "Well done, son" from Jonathan. In an episode where Lionel froze all of Lex's assets, and Lex crashed at the Kent farm rather than submit to Lionel, Jonathan foisted a bunch of farm chores off on Lex to earn his keep. Jonathan later compliments Lex that he did every filthy, backbreaking job Jonathan could think of, did them without complaining, and did them ''well''.
* WhamEpisode:
%%** "Reckoning"
%%** "[[Recap/SmallvilleS07E16Descent Descent]]"
%%** "[[Recap/SmallvilleS10E11Icarus Icarus]]"
** Season 10's [[spoiler:"Fortune" was--based on the fact that Allison Mack was only going to be in five episodes in the FinaleSeason--Chloe's probably-final appearance, so her leaving in this episode was not a surprise. The fact that Oliver goes with her for an undetermined length of time is the surprise. Oh, [[ArsonMurderAndJaywalking and Tess and Emil might just be]] [[PairTheSpares hooking up now]]...]]
* WhatCouldPossiblyGoWrong: Spoken verbatim by Chloe in "Masquerade." Naturally, [[TemptingFate quite a bit does.]]
* WhatHappenedToTheMouse:
** Lucas, Lex's brother, vanishes after his first episode. Initially justified as he was in hiding from Lionel. However, when both Lionel and Lex die, their is no reason for him not to step forward and claim a huge inheritance. One could argue that Lex's will left everything to Tess, so there was nothing for Lucas to claim. Still, it's a bit odd he was never mentioned, either after Lex's death, in Earth-2 (unless he never existed there), or after [[spoiler: it's revealed Tess is ''also'' a Luthor]]. It's also possible that Lex had Lucas killed to avoid the inheritance problem after Lionel's death. [[spoiler: Tess]] didn't know about the Luthor-blood thing yet, so she was no threat.
** Averted with Pete, who vanishes for several seasons, but [[TheBusCameBack eventually does resurface]] and Clark and him get closure.
** Conner Kent shows up partway through Season Ten. Clark invites him to live on the farm and he enrolls in Smallville High. A couple of episodes later he's 'visiting Martha in Washington' and he never shows up or is mentioned again. Not even, y'know, when the world is ending and having another person around with Clark's powers could be useful.
* WhoWantsToLiveForever:
** It's strongly implied by both more knowledgeable aliens and characters with PsychicPowers that Clark will outlive his loved ones. This was a recurring theme especially during Season 7, where it was used to create tension in Clark and Lana's relationship.
** [[spoiler:Lionel himself never intended to live forever, as he gave his own heart to resurrect Lex in exchange for having Darkseid claim his soul.]]
* WhyAreWeWhispering: In the pilot, between Pete Ross and Chloe Sullivan (Chloe Sullivan doesn't know why they're whispering and doesn't whisper herself.
* WickedCultured: Lionel and Lex Luthor. Tess too. [[spoiler:It runs in the family.]]
* WildTeenParty: Clark hosts one in "Jitters." It just about wrecks the house.
* WillTheyOrWontThey: Clark & Lois.
* WithFriendsLikeThese: Clark and Pete the former repeatedly forced Clark to lie, cheat, steal, threatened expose his secret then act like nothing happened. This is especially seen in "Velocity" and "Hero".
** This is a major thing with Clark and Lex before they become enemies. Even while claiming to be the best of friends, they are always heavily distrustful of one another.
* WithGreatPowerComesGreatInsanity: All over the place, especially in the earlier seasons. Kryptonite infection usually results in violent obsession in those who gain powers, and the early seasons are littered full of "freak of the week" encounters with previously normal (if often a bit self-centered or jerkish) people who gain powers and soon embark on insane rampages.
* WorldOfMuscleMen: Maybe because it's based on the ''Franchise/{{Superman}}'' comics but the series has not just Clark but all the males muscular.
* WritersCannotDoMath: The recon done in "Power" where instead of Lana leaving Clark of her own free will she was kidnapped by Lex. This means that Lex was building the Prometheus suit to fight Clark and save his battered body long before he was even aware of Clark's secret and was wounded in the Fortress. Sure he had deals going on like Aries that led to it but Lana seemed to be on to it way sooner than she should have. That was cool but everything about it here just fell totally flat. There is no way Lex would have let it get out to Lana like that, especially after the Fortress when he needed it the most.
* WroteTheBook:
** Lex claims the Luthors wrote the book on uncomfortable silences.
** Chloe also says she wrote the book on pining over Clark.
* XanatosGambit:
** "Absolute Justice" has [[spoiler:Amanda Waller and Checkmate. She uses her Suicide Squad (or a member of it) to go after the JSA, not really caring that he kills a couple but killing him when he tried to kill everyone. Why? She wanted to bring them out of hiding to join the budding JLA and prepare for the coming Apocalypse (or is it Apokolips?)]].
** Both Clark and Bizarro were searching for Dax-Ur for different reasons. Brainiac separately told both of them to find Dax-Ur's shield, a device which would transport the user to Dax-Ur himself. Clark manages to find it and locates Dax-Ur. It didn't matter to Brainiac who reached Dax-Ur. What's important was that the activation of the shield emitted a beacon which allowed Brainiac to reach Dax-Ur, who had created him. Brainiac wanted to download information from Dax-Ur's brain to upgrade himself and become more powerful.
** In Season 5, Brainiac had wanted to use Clark as Zod's vessel. When that didn't work, he simply used Lex as Zod's vessel.

* YetAnotherChristmasCarol:
** "Lexmas," actually subverted when [[spoiler:Lex decides to pursue money and power in order to save the life of his potential future wife Lana, who would have died if he had become a NiceGuy, setting up his future status as the antithesis of Franchise/{{Superman}}]]. Really more of an ItsAWonderfulPlot.
** Despite not happening at Christmas, "[[Recap/SmallvilleS10E04Homecoming Homecoming]]" fits the mold better, with [[spoiler:Brainiac 5 showing Clark his past, present, and future to get him back on track]].
