"The ultimate villain of the story, who's causing the problem the heroes must solve."

Note that Big Bad is not a catch-all trope for the biggest and ugliest villain of any given story. The BigBad is the one who turns out to be behind several other seemingly independent threats.


[[folder:Channels / TV Series in general]]
* Creator/DisneyChannel shows often have Big Bads
** Dr. Ronald Olsen in the movie for ''[[Series/TheSuiteLifeOfZackAndCody The Suite Life On Deck]]''.
** ''Series/SonnyWithAChance'' had [[spoiler: Penelope]] as the Big Bad of the ''Sonny With a Secret'' story arc.
** ''Series/WizardsOfWaverlyPlace'' had [[spoiler:Stevie Nichols]] in season 3 and Gorog in season 4. By extension, Gorog is the BiggerBad of the entire DisneyChannelLiveActionUniverse. Gissele is this in the first movie and Domminic in the second.
** Lanny in ''Series/PairOfKings'', [[spoiler: eventually has a HeelFaceTurn and the role is usurped by Kaita]].
** Sensei Ty in ''Series/KickinIt''.
** ''Series/ANTFarm'' has a BigBadEnsemble of Lexi Reed and Principal Susan Skidmore. Out of the two, Skidmore is the best candidate for Big Bad, as Lexi is softened into more of a LovableAlphaBitch overtime. Season 3 had [[Series/SuiteLifeOnDeck Hashimoto]].
** ''Series/{{Jessie}}'' also has a BigBadEnsemble, this one with Rhoda Chesterfield and Nanny Agatha.
** ''Series/MyBabysittersAVampire'' has Jesse for the movie, [[spoiler:and FinalBoss of season one]]. [[spoiler: Vice Principal Stern]] for season two.
** Principal Perry and Marcus Davenport were in the running for this in ''Series/LabRats'', but the real threat in Season 2 turned out to be Douglas Davenport. In Season 3, [[spoiler:Douglas [[HeelFaceTurn turns good]]]] and the role shifts to Victor Krane, Douglas Davenport's benefactor.
** ''Series/MightyMed'' has The Annihilator.
* Creator/{{Nickelodeon}} shows often have Big Bads.
** The movie ''Drake and Josh Go Hollywood'' has Milo [=McCary=]. The next movie ''Really Big Shrimp'' has Alan Krim. The third one has parole officer Perry J. Gilbert, the only one who does a HeelFaceTurn in the end. Doesn't make the movie any less terrible though.
*** The show itself had Megan Parker.
** Nevel Papperman in ''Series/{{iCarly}}''
** Augustus in ''Series/TheTroop''.
** Molly Garfunkel in ''Series/HowToRock''.
** George Hawk and then Jett Stetson in ''Series/BigTimeRush''.
** ''Series/{{Victorious}}'', [[SitcomArchNemesis Jade West]] as TheHeavy, but she has a constant HeelFaceRevolvingDoor. Of course, the special "Freak the Freak Out" gives Hayley Ferguson as its main antagonist, putting her in an EvilVersusEvil situation with Jade. The special "Locked Up" has the Yerbian Chancellor as its BigBad. Then there is Mason Thornsmith in the special "Tori Goes Platnium".
** ''Series/EveryWitchWay'' has Principal Torres in the first season. Season two has [[spoiler: a BigBadEnsemble between Desdemona, Jax Nova and Evil!Emma. It turns out that Jax is working as TheHeavy for his father who is set up for season three.]]
** Danielle Atron in ''Series/TheSecretWorldOfAlexMack''


* ''Series/{{The 100}}'' has two {{Big Bad}}s in its first season, one for the Ark storyline and one for the Ground storyline. On the Ground, the Big Bad is the Commander of the Grounders who orders them to attack the 100 (though she doesn't appear in person until Season 2). On the Ark, the Big Bad isn't a character, but the space station's failing life support systems and overall lack of resources, which force the characters into a desperate struggle for survival, though the person responsible for the attempted murder of Jaha may count as well. In Season 2,
Cage Wallace emerges as the Big Bad in the latter half of the season after he usurps the role from his father, Dante.
* ''Series/TwentyFour'':
** Season 1: [[spoiler: Victor Drazen]]
** Season 2: [[spoiler:Peter Kingsley, although he's under the employ of [[BiggerBad Max and Alexander Trepkos]]]].
*** The Game: [[spoiler: Max]]
** Season 3: [[spoiler: Stephen Saunders]]
** Season 4: [[spoiler: Habib Marwan]]
** Season 5: [[spoiler: [[PresidentEvil President Charles Logan]].]]
** Season 6: Abu Fayed for the majority of the season, then [[spoiler: [[ArchnemesisDad Phillip Bauer]] [[BigBadDuumvirate and Cheng Zhi]].]]
** Season 7: [[spoiler: Alan Wilson, although Jonas Hodges got more screen time, and much of the last quarter equally focuses on [[EvilFormerFriend Tony Almeida's]] attempt to kill Wilson while also threatening everyone else to do so.]]
*** [[spoiler: Alan Wilson and Jonas Hodges were both in the same OmniscientCouncilOfVagueness behind the season's events, Wilson was "first among equals" so to speak.]]
** Season 8: [[spoiler: [[BigBadDuumvirate Charles Logan and equally corrupt Russian President Yuri Suvarov]].]]
*** [[spoiler:[[FallenHero Jack Bauer]] becomes this in the final 6 episodes though makes a HeelFaceTurn in the last episode.]]
** Season 9: Margot Al-Harazi, then [[spoiler: [[HijackedByGanon Cheng Zhi]].]]

* ''Series/TheAdventuresOfBriscoCountyJr'': The main Big Bad is John Bly, who is eventually revealed to be an even bigger threat than previously thought when it is discovered that [[spoiler:he's actually a time traveler from Earth's far future who will institute a 1,000-year reign of terror.]]
* Season One of ''Series/AgentsOfSHIELD'' has the [[TheGhost mysterious and unseen]] individual known only as The Clairvoyant, who is behind [[NebulousEvilOrganization Project Centipede]] and [[ArcWelding much else]] of what's happened so far in the series. [[spoiler: "Turn, Turn, Turn" reveals that he's [[BigBadFriend Agent John Garrett]], who is actually a [[TheMole top HYDRA agent]]]].
** Season Two has begun to set up [[BigBadEnsemble several Big Bads]] all working against SHIELD and each other: [[InspectorJavert General Talbot]], with the US Military; [[MadScientist Daniel Whitehall]], real name [[ThoseWackyNazis Werner Reinhardt]], a major player in ComicBook/{{HYDRA}}; and Skye's father, "[[MadDoctor the Doctor]]". However, by the midpoint of the season, Talbot and the military have [[EnemyMine called a truce]] with ComicBook/{{SHIELD}}, while Whitehall and the Doctor have [[VillainTeamUp allied]]. And then it gets even more complicated when [[spoiler: they're joined by Ward (Garrett's former Dragon), who's running his own agenda, while the audience discovers that the Doctor is just trying to get close enough to kill Whitehall in revenge for him killing the Doctor's wife years earlier.]]
* ''Series/{{Alphas}}'': The main villains are the Red Flag organization, the collective EvilCounterpart to Rosen's Alpha team. Specifically, the BigBad would be Red Flag's leader, [[ImmortalityImmorality Stanton Parish]], who so far has only been on screen for about five minutes total in season 1 finale, but has still managed to show himself as a master [[TheChessmaster Chessmaster]], and a ''very'' dangerous opponent.
%% * ''Series/AmericanHorrorStory'' has several.
* ''Series/{{Angel}}'':
** The show has the Senior Partners at Wolfram and Hart as the main antagonist for the entire series, who were never properly seen and worked through their various lawyers and other agents like Lindsey, Lilah and Hamilton. On occasion their plans are disrupted by other evil forces but they represent the overriding evil Angel has to face.
** Season 3 has a massive BigBadEnsemble with Daniel Holtz, Liah Morgan, and Sajjhan. Out of those three, Daniel comes up as the domminate threat and Sajjhan is the OutsideContextVillain.
** Season 4 has Jasmine, ostensibly one of ThePowersThatBe who manipulated events across the series in order to gain a physical form. She had her own [[TheDragon Dragon]], The Beast, who massacred the LA Wolfram & Hart branch. Angelus also took over the role for a short while in in the fourth season after killing The Beast, until he was re-ensouled again by Willow.
** Season 5 returned to the Senior Partners, but with a twist in that Angel and his team were given Wolfram and Hart resources to do whatever they wanted with, making it an EnemyMine situation. They kept their presence known through their Dragons, Marcus Hamilton and the Circle of the Black Thorn led by Archduke Sebassis.
** Gunn was this in ''After the Fall''.
* ''Series/ArrestedDevelopment'':
** Seasons 1-3 have [[spoiler: Lucille Bluth]], who, as revealed in (what was originally) the show's GrandFinale, is behind all of the corruption in the Bluth company.
** The story arc started by Season 4 seems to have [[spoiler: Sally Sitwell]] (for [=GOB's=] story at the very least), and possibly [[spoiler: whoever killed Lucille 2 (every member of the family has a motive)]].
* Since ''Series/{{Arrow}}'' runs two storylines simultaneously (one in the present, the other flashbacks to Oliver's time on the island), it naturally has two {{Big Bad}}s per season.
** Season One: The present has [[spoiler: [[VisionaryVillain Malcolm Merlyn]]]]/[[EvilCounterpart The Dark Archer]], while the island has [[PrivateMilitaryContractor Edward Fyers]] [[spoiler: (until it turns out that he's working for a mystery woman, revealed retroactively to be Amanda Waller)]].
** Season Two: The present has [[spoiler: [[EvilFormerFriend Slade Wilson]][=/=]ComicBook/{{Deathstroke}}]], TheManBehindTheMan to initial-seeming BigBad [[DarkMessiah Sebastian "Brother" Blood]], and the island has [[MadScientist Dr. Anthony Ivo]]. [[spoiler: Then we see Slade's FaceHeelTurn occur in the flashbacks, where he usurps Ivo's resources, making him the overall BigBad of the whole season.]]
** Season Three: [[BigBadEnsemble Duties are split]] between [[spoiler: [[NotQuiteDead Malcolm Merlyn]]]] and [[spoiler: [[TheDreaded Ra's Al-Ghul]]]], [[spoiler: although recently Oliver has been forced to [[EnemyMine ally himself]] with Malcolm just to stand a chance against Ra's]]. The flashbacks set in Hong Kong also split duties, this time between [[KnightTemplar Amanda]] [[IceQueen Waller]] and [[TheTriadsAndTheTongs China White]].

* ''Series/BabylonFive'' always had the [[AbusivePrecursors Shadows]] as the biggest threat, with their influence still being felt even after their defeat, but not always the obvious BigBad.
** Season 1 has the [[SpacePirates Raiders]] and [[ANaziByAnyOtherName Home Guard]] as the primary villains, though later in the season the groundwork for the Shadows started to be laid.
** Seasons 2, 3, and the first part of 4 all have the Shadows as BigBad directly, [[MouthOfSauron represented]] (but not led) by [[ManipulativeBastard Mr. Morden]].
** The remainder of Season 4 had [[PresidentEvil President Clark]].
** Season 5 had more of a BigBadEnsemble, with [[PsychicPowers Bester]] and [[ScaryDogmaticAliens the Drakh]] (former servants of the Shadows) as the major players.
* ''Series/BatesMotel'': Season 1 has Jake Abernathy.
* ''Series/BattlestarGalacticaReimagined'': (John) Cavil aka Number One.
* ''Series/BigWolfOnCampus'': The Werewolf Syndicate, which was led by legitimate BigBad, but [[spoiler: they are eventually killed off, so the leaders [[BigBadWannabe incompetent son]] takes over.]]
* ''Series/BlakesSeven'': Had Servalan, especially in Season 3 when she's risen to [[PresidentEvil President]] of the [[EvilEmpire Federation]] and is answerable to no-one. Despite her reduced status in Season 4, she's still ultimately behind most of the problems the Seven face.
** The Andromedans are the ultimate Big Bad of Season 2, joining the search for Star One in order to use it to wipe out humanity, and forcing Blake and his crew into an EnemyMine situation with Servalan and the Federation to stop them.
* ''Series/BoardwalkEmpire'':
** Season 1: The D'Alessio Brothers and Arnold Rothstein
** Season 2: [[spoiler: Jimmy Darmody]]
** Season 3: Gyp Rossetti
** Season 4: [[BigBadEnsemble Dr. Valentin Narcisse and Agent James Tolliver]]
** Season 5: [[spoiler:[[BigBadDuumvirate Lucky Luciano and Meyer Lansky]]]]
* ''Series/BreakingBad'':
** Tuco Salamanca became this towards the end of Season 1, but died shortly into the second season [[spoiler:after Hank Schrader shot him in the head]].
** The Cousins are this for the first half of Season 3. [[spoiler:They later get killed by Gus' machinations]].
** The end of Season 3 and all of Season 4 had Gustavo 'Gus' Fring, with the Cartel briefly entering as the BigBadEnsemble. The first half of Season 5 had [[spoiler:[[VillainProtagonist Walter White.]]]] The second half of Season 5 has [[spoiler:[[ChekhovsGunman Jack Welker]].]]
** For a while, it looked as though Fring might be a lesser threat than the brutal Mexican drug cartel to which he paid tribute in return for jurisdiction over his meth market. He put those doubts to rest [[spoiler: when he successfully assassinated the cartel's leadership]].
** Lydia Rodarte-Quayle is the series' big bad; Crazy 8, Tuco and Fring are lesser predecessors to Lydia, who can expand the cartel into an intercontinental empire. But her meek style and relative inexperience avert the big bad cliches and enable [[spoiler: Jack]] to act as DragonInChief. Lydia's descent into crime in the final season mirrors Walter White's in Season 1.
* ''Series/BuffyTheVampireSlayer'' is the TropeNamer, and would occasionally introduce "decoy" Big Bads to set up a surprising revelation:
** [[Film/BuffyTheVampireSlayer The Movie]] / The Origin Comic: [[AristocratsAreEvil Count Lothos]]
** Season 1: TheMaster
** Season 2: First the [[DarkMessiah Anointed One]] was a decoy big bad. Spike and Drusilla are the Big Bads of the first half of the season, and Angelus is the big bad of the second half after his FaceHeelTurn.
** Season 3: [[AffablyEvil Mayor Richard Wilkins]]
*** Subverted twice with Mr. Trick, initially played off as the Big Bad himself, then as TheDragon when the true Big Bad shows. Then the real [[TheDragon Dragon]] shows...
** Season 4: Most of the season has no Big Bad, although Spike returns early on as a decoy Big Bad and [[MadScientist Professor Walsh]] is shaping up to be a good candidate before she is killed mid-season. Late in the season, [[HalfHumanHybrid Adam]] first appears as TheDragon and becomes the [[DragonAscendant Big Bad]] and FinalBoss.
** Season 5: [[PhysicalGod Glory, a.k.a Glorificus]]
** Season 6: Appears to have a [[BigBadDuumvirate Big Bad Triumvirate]] in the form of The Trio of Warren, Johnathan, and Andrew. It quickly becomes clear that Warren is the dominant personality of the three, and he becomes the BigBad of the season, with his murder of Tara ultimately causing [[BreakTheCutie Willow]] to [[WoobieDestroyerOfWorlds snap]] and become the FinalBoss after killing him. [[WordOfGod Joss Whedon has claimed]] that "life itself" was the Big Bad of Season 6.
** Season 7: [[MadeOfEvil The First Evil]] thought some people see it as "The Big Bad" and BiggerBad for the series.
** Season 8 Comic: Twilight, [[spoiler:the sentient dimension, not Angel.]]
** Season 9 Comic: Has a BigBadDuumvirate of rogue Slayer Simone Doffler and [[DragonInChief Severin]] in Buffy's series, and [[spoiler:Whistler]], with CoDragons Peral and Nash, in ''Angel & Faith''.

* ''Series/{{Charmed}}'', after it partially abandoned its MonsterOfTheWeek premise in season 3:
** Season 1: To some extent, Rex Buckland and Hannah Webster in the first half of the season.
** Season 2: No Big Bads.
** Season 3: The Triad & Cole Turner, although by the end of the season BiggerBad the Source has become more of a direct threat.
** Season 4: The Source. (Both the original and Cole) and ultimately the Seer in the end.
** Season 5: Cole eventually becomes this for the first half.
** Season 6: Gideon.
** Season 7: The Avatars (sort of), Zankou from the demons and Inspector Sheridan in the "real world".
** Season 8: The Triad and Christy Jenkins.
* ''Series/ChoujinkiMetalder'': [[EvilOverlord God Neros]].
* ''Series/{{Chuck}}'': None present in Season One, but subsequent seasons had them:
** Season Two: Ted Roark.
** Season Three: [[spoiler: Daniel Shaw]]
** Season Four: Alexei Volkoff
*** [[spoiler:Supplanted by his daughter Vivian Volkoff in the second half of the season.]]
** Season Five: Decker
*** [[spoiler:Seeing as he's been blown up, he's been supplanted by Daniel Shaw, the real person behind the conspiracy to bring down Chuck.]]
*** [[spoiler: With Shaw depowered and imprisoned, he's been supplanted by Nicholas Quinn, who will be the series's final Big Bad.]]
** Ted Roark and many season one villains were part of Fulcrum, which in turn was part of The Ring, which was run by The Director and The Elders in season three, and was responsible for [[spoiler: Daniel Shaw]]'s [[FaceHeelTurn fall to evil.]]
* In the second half of ''CityHomicide'' Season 2, Billy Pierce fills this role as he frames Superintendant Waverley for corruption, before kidnapping and murdering her teenaged son.
* ''Series/{{Community}}'' did without for two seasons, but as in season 3 Chang steadily rose to power after the previous season's HumiliationConga, taking over the school in the four-part finale and kicking out the Greendale Seven.
** Though you could argue that Pierce fulfills this role in season 2, [[TookALevelInJerkAss considering]] [[ManipulativeBastard his actions]].
* ''Series/{{CSI}}'': Despite being a science-themed series heavily grounded in reality aside from a few ThroughTheEyesOfMadness scenes, there were several:
** Season 1 and 2: EvilGenius serial killer Paul Millander
** Season 7: The Miniature Killer aka Natalie Davis
** Season 7 Keppler mini-arc: CorruptCop Frank [=McCarty=]
** Season 8: Crime boss Lou Gedda, usurped by [[spoiler:Undersheriff [=McKeen=]]]
** Season 10: "Dr. Jekyll" aka Charlie Dimasa
** Season 11: Nate Haskell, after serving as a secondary villain in several earlier season episodes.
** Season 12: [[spoiler:[[BigBadFriend Laura Gabriel]]]] for Catherine's departure arc and [[spoiler:[=McKeen=] again]] in the finale
* ''CSIMiami'': Clavo Cruz and the Mala Noche.
* ''CSINewYork'': Shane Casey, the 333 caller, the Cabbie Killer, and the Compass Killer.

* ''Series/{{Danger 5}}'' has a rather traditional BigBad - Hitler.
* ''DarkAngel'':
** Season 1: Manticore, at first personified by Colonel Donald Lydecker, who was later ousted by the EvilerThanThou Madame X/Renfro.
** Season 2: Ames White, who is secretly a government agent assigned to cover up Manticore by hunting down transgenics, and more secretly a leader in the [[AncientConspiracy Familiar Breeding Cult]].
* Season 1 of ''DarkOracle'' has EvilSorcerer [[SmugSnake Omen]], who is revealed to be the one who saddled Lance and Cally with the DarkWorld comic in the first place. In Season 2, [[LonersAreFreaks Vern]] makes a [[BigBadWannabe valiant attempt]] at becoming the new main villain, before being upstaged by Omen's return. Omen himself has [[CreepyTwins Blaze and Violet]] in back of him, while [[spoiler: [[TheManBehindTheMan The Puppet-Master]]]] is in back of them.
* ''Series/{{Deadwood}}'': [[CorruptCorporateExecutive George Hearst]] in season 3.
* ''Series/DesperateHousewives'' has a major mystery for each season, thus who committed said crime can be considered as the BigBad.
** Season 1: [[spoiler: Mary Alice Young]], since she was the one who killed Deirdre.
** Season 2: Matthew Applewhite
** Season 3: Gloria Hodge
** Season 4: Wayne Davis
** Season 5: Dave Williams
** Season 6: Patrick Logan
** Season 7: Felicia Tilman
* In ''Series/{{Dexter}}'', the hero is also the villain, in a version of the VillainProtagonist and Heroic Sociopath tropes, so in one sense Dexter is always his own Big Bad. Each season has its own exterior Big Bad as well.
** Season 1: The Ice Truck Killer, who is actually [[spoiler:Dexter's brother, Brian, who is a doctor working on the case with the police]].
** Season 2: Dexter is clearly his own big bad, as he's trying to avoid being caught. There are superficial decoy Big Bads: Lundy, the would-be HeroAntagonist, Doakes, [[spoiler:and finally Lila]].
** Season 3: [[spoiler:Miguel Prado.]]
** Season 4: Trinity.
** Season 5: [[spoiler:Jordan Chase.]]
** Season 6: Professor Gellar and Travis Marshall. [[spoiler:But it turns out it's just Travis. Gellar was DeadAllAlong.]]
** Season 7: Isaak Sirko, [[spoiler: Hannah [=McKay=], and Maria [=LaGuerta=], although [=LaGuerta=] is a HeroAntagonist.]]
** Season 8: The Brain Surgeon [[spoiler:(aka Oliver Saxon/Daniel Vogel)]]
* ''Series/{{Dollhouse}}'' had Alpha causing every problem the Dollhouse crew faced in Season 1. Season 2 has the Rossum Corporation as a whole set up this way, but only as of "Getting Closer" (2x11) do we know who the MagnificentBastard in charge of it is: [[spoiler: Boyd Langton]].
* ''Series/DoubleTheFist'' has no main antagonist, but Mephisto has entered a similar situation at least twice.
** In "Bush Bash", he is possessed by a Demi God and tries to destroy the forest (And the Fist Team) using an army of cloned... lumberjack pandas...
** In Series Two, he almost plays the trope straight by secretly joining the Medieval Recreationists as their leader, and formulated a EvilPlan against the team.
* Several seasons of ''Series/DoctorWho'' have a BigBad:
** Seasons 2 to 4: The Daleks, the main villains of practically every story longer than four episodes. The Meddling Monk serves as a temporary boss of Seasons 2 and 3 but is too much of an IneffectualSympatheticVillain to really qualify. Mavic Chen and the [[LegionOfDoom Galactic Council]] could be partially considered this for Season 3 as well, working with the Daleks even though the Daleks ultimately betray them.
** Season 5: The Cybermen [[RoguesGallery and]] the Great Intelligence
** Season 8 and 9: The Master; he was the villain of literally every episode of Season 8 and although he appears less in Season 9 he is still regarded as the biggest threat to Earth by UNIT. The Master basically played this role for the Third Doctor's era (although he doesn't appear in Seasons 7 or 11).
** Season 10: The Daleks, who act as the TrueFinalBoss above the Master, employing him to start an interplanetary war to destabilise the region while preparing a giant invasion force to take over in the aftermath.
** Season 15: The Sontarans, who are indirectly responsible for the events of the season opener before turning out to be [[TheManBehindTheMan behind]] the Vardans in the finale.
** Season 16: The Black Guardian, but he doesn't show up until the final episode.
** Seasons 18 and 19: The new form of the Master.
** Season 20: The Black Guardian
** Season 23: The Valeyard and the [[spoiler:Time Lord High Council]].
** Season 26 reveals that [[spoiler:Fenric]] was manipulating events in this and the previous two seasons.
** Series 1: The Dalek Emperor and his faction of half-human Daleks.
** Series 2: Started off with John Lumic and his version of the Cybermen. They return for the finale, now led by a generic Cyber-Leader, but they're usurped by the Cult of Skaro (led by Dalek Sec); both factions spent more time [[EvilVersusEvil fighting each other]] than the heroes.
** Series 3: TheMaster, [[ArchEnemy naturally]].
** Series 4: Featured the resurgent Dalek Empire, represented by Davros, but he's technically a "pet" for the Supreme Dalek.
** Year of Specials / The End of Time: Rassilon, founder of Time Lord society, brought back during the Time War so he could save his people - even if it means destroying the rest of the universe.
** Series 5 / 6: "The Silence", a movement determined to kill the Doctor in order to avert a prophecy that he will reveal his most terrible secret. Indirectly caused most of series 5 despite not appearing until the series 6 opening.
*** Though it later turns out that they were an [[KnightTemplar extreme]] RenegadeSplinterFaction. The main Papal Mainframe that they used to work for are fairly decent people. And it is still questionable how deliberate the events of Series 5 were.
** Series 7 has the [[EldritchAbomination Great Intelligence]]. While it doesn't show up until the latter half of the season, its indirect involvement [[spoiler: through Clara]] stretches back to the start of the season.
*** Considering the events of that episode, the Great Intelligence could be considered the BigBad for all Doctors before the 12th.
** Anniversary Specials/The Time of the Doctor: The Daleks. The specials have something of a BigBadEnsemble but the Daleks are the most dangerous and the [[FinalBoss last ones standing]].
** In the 50th anniversary OfficialParody sketch ''Recap/TheFiveishDoctorsReboot'', the Big Bad is Doctor Who showrunner Creator/StevenMoffat.
** Series 8 has the enigmatic Missy, who turns out to be [[spoiler: [[GenderBender a female form of the Master]]]] and [[VillainTeamUp allied with]] the Cybermen.
* ''Series/{{Dominion}}'' has the ArchangelGabriel as the primary threat, though [[spoiler: [[ArchangelUriel Uriel]] is [[PlayingBothSides playing him and Michael against each other]] for her own ends]]. [[CorruptPolitician David Whele]] and [[LadyMacbeth Arika]] are also both taking advantage of the situation for their own agendas as well [[spoiler: though Arika is working with Uriel.]]

* ''Series/{{Elementary}}'': Season 1 has [[ArchEnemy Moriarty]] [[spoiler: [[CompositeCharacter aka]] [[SamusIsAGirl Irene Adler]]]].

* ''Series/{{Farscape}}'': A succession of {{Big Bad}}s. First it's Crais, then Scorpius, then Grayza, who eventually [[BigBadEnsemble shares the limelight]] with the Scarran Emperor. Each of these get progressively more epic and ambitious.
* It is strongly implied in ''Series/{{Firefly}}'' that the Big Bad was the Blue Sun Corporation, which apparently worked with the Academy.
* ''Series/TheFlash2014'' has the Reverse-Flash [[spoiler: who turns out to be Harrison Wells... aka Eobard Thawne.]]
* ''Series/TheFollowing'' has [[SerialKiller Joe Carroll]], though Season 2 expands it into a BigBadEnsemble between him and fellow cult leader [[spoiler: [[BitchInSheepsClothing Lily Gray]]]].
* ''Series/{{Fringe}}''
** Season 1: ZFT, led by David Robert Jones.
** Seasons 2 & 3: [[spoiler: The alternate universe, led by Walternate.]]
** Season 4: [[spoiler: Appears to be Jones again, but it turns out he was working for William Bell.]]
** Season 5: [[spoiler: The Observers]]

* ''Series/GameOfThrones'':
** Season 1: Cersei and Jaime Lannister
** Season 2: Joffrey Baratheon
** Season 3: Tywin Lannister
** Season 4: Tywin Lannister
* ''Series/{{Garo}}'': [[FallenHero Barago]].
** ''Series/GAROTheOneWhoShinesInTheDarkness'': [[HumansAreTheRealMonsters Tousei Kaneshiro]].

* ''Series/GossipGirl'':
** Season 1: Georgina Sparks
** Season 2: Poppy Lifton
** Season 3: William Van der Woodsen
** Season 4: Juliet Sharp (part I) and Russell Thorpe (part II)
** Season 5: BigBadEnsemble of Tripp Van der Bilt, Louis Grimaldi and Diana Payne.


* In both the original and [[Series/HawaiiFive0 remake]] of ''Series/HawaiiFiveO'' the Big Bad is Wo Fat. Almost every criminal activity is controlled by him.
* ''Series/{{Heroes}}'': Sylar is the overall BigBad, but each season has [[BigBadEnsemble another.]]
** Volume 1: [[spoiler:Mr. Linderman]]
** Volume 2: [[spoiler:Takezo Kensei/Adam Monroe]]
** Volume 3: [[spoiler:Arthur Petrelli]]
** Volume 4: [[spoiler:Initially Nathan, then [[TheStarscream usurped]] by [[TheDragon Danko]], who is in turn usurped by Sylar in the season finale.]]
** Volume 5: [[spoiler: Samuel Sullivan]]
* ''[[Series/{{Highlander}} Highlander: The Series]]'' after it partially abandoned its VillainOfTheWeek format.
** Season 1: No Big Bad.
** Season 2: James Horton.
** Season 3: Antonin Kalas.
** Season 4: Jack Shapiro.
** Season 5: Kronos.
** Season 6: Ahrimin for the opening arc, Liam O'Rourke for the finale (with [[BackForTheFinale James Horton]] as the Big Bad of the alternate timeline).
* ''HomeAndAway'' had the Summer Bay Stalker, AKA Zoe [=MacCalister=], AKA Eve Jacobsen, during 2005 and 2006.
** Angie Russell was this in late 2002, early 2003.
** Sarah Lewis was responsible for the armed siege that formed the mid-season cliffhanger in 2004.
** Johnny Cooper in late 2006/early 2007, later making a BackForTheDead return in the first half of 2008.
** Suzy Sudiro and Derrick Quaid ran the human trafficking operation that took up the 2009 season.
** Criminal gang leader and drug supplier Darryl Braxton seemed to fill this role for the first half of the 2011 season, although the SortingAlgorithmOfEvil saw rival gang leader Jake Pirovic move above him for the latter half of the season.
** Adam Sharpe filled this role in late 2012/early 2013.
** The latter half of 2013 had something of a BigBadEnsemble between the Sanctuary Lodge cult, led by Murray Granger and Ethan [=MacGuire=], and SadistTeacher Jade Montgomery, until the two storylines [[CollidingCriminalConspiracies collide]] in the finale.
** Jake Pirovic returns in 2014 just long enough to kill another main character and then die himself. By the finale, unscrupulous music and [[spoiler: sex tape]] producer Neive Devlin has become the Big Bad.

* ''Series/JaneTheVirgin'': Season 1 Has drug lord Sin Rostro "The Man With No Face" [[spoiler: aka Rose Solano]]
* ''Series/{{Justified}}'': Boyd Crowder tends to be the series' default BigBad, but each season also has a contender.
** Season 1: [[{{Archnemesis Dad}} Bo Crowder]], whose attempt at rebuilding his criminal empire becomes the main focus of the season's last half. There's also Gio Reyes, who is behind various other threats over the course of the season, and becomes Bo's partner just before the finale.
** Season 2: [[EvilMatriarch Mags Bennett]], whose plan to ripoff Black Pike Mining drives most of the season's action, while her sons Doyle, Dickie, and Coover plot against Raylan and Boyd alike.
** Season 3: [[PsychoForHire Robert]] [[OutsideContextVillain Quarles]] of the Detroit Mob, who tries to take control of Harlan County's drug trade in the aftermath of Mags' fall, running afoul of Raylan and Boyd in the process.
** Season 4: Quarles' adopted father, Theo Tonin takes over. His desire to see Drew Thompson dead drives the storyline, while the investigation into Drew is in and of itself aimed at bringing Theo down. In the last episode, Nicky Augustine, who has been acting as Theo's DragonInChief, attempts to launch a coup d'etat, and becomes the focus of Raylan's ire.
** Season 5: There's a few contenders, including [[ArcVillain Johnny Crowder]], Mr. Yoon & Alberto Ruiz of the Mexican cartel, longrunners Wynn Duffy & Mr. Picker, and Boyd himself, but in the end [[CorruptHick Daryl Crowe Jr.]] emerges as the main threat, with Raylan's attempt to arrest him, and Boyd's attempt at getting rid of him, taking up the final part of the season.
* ''Series/JuukouBFighter'': [[BadBoss Emperor Gaohm]].

* The textbook BigBad for the various Showa-period ''Franchise/KamenRider'' series was Great Leader. Although we never learn ''precisely'' what it is, it's claimed to be everything from a (relatively) mundane mutant terrorist to a [[EldritchAbomination living embodiment of hate and suffering]] who will exist AsLongAsThereIsEvil. Typically, if there was a series where it ''wasn't'' the BigBad, it'd pop up in the next series and claim to have been [[HijackedByGanon the one bossing around the previous show's villains]]. Other, more recent series have had the following as main villains:
** ''Black'' had the Creation King.
** ''Black RX'' had [[GalacticConqueror Grand Lord Crisis]], who... may be Great Leader, it's not entirely clear, but they have the same voice actor, whose distinctive voice was Great Leader's calling card.
** ''Shin'' had [[TheMafia the Syndicate]] as well as [[TheGovernment the CIA]].
** ''ZO'' had the Neo Organism.
** ''J'' had [[HiveQueen the Fog Mother]].
** ''Kuuga'' had N Daguva Zeba, the Grongi Lord.
** ''Agito'' had [[AbusivePrecursors the Overlord of Darkness]].
** ''Ryuki'' had [[WellIntentionedExtremist Shiro Kanzaki]].
** ''555'' had the Smart Brain heads and the Orphnoch King.
** ''Blade'' had [[CorruptCorporateExecutive Hiroshi Tennoji]], though at the end of the series [[spoiler:he was usurped by Giraffe Undead, the last member of the Royal Club, who was ticked at being used by Tennoji. Ultimately however, the real Big Bad may just have been the Sealing Stone, since it was what created the Undead in the first place.]]
*** TheMovie has [[EvilCounterpart the Albino Joker]] as the BigBad.
** ''Hibiki'' had The Man and The Woman and all their myriad clones. [[spoiler:We don't even meet the actual originals until the finale. And its even possible that they aren't the originals after all...]]
** ''Kabuto'' had Negishi.
** ''Den-O'' had Kai the Singularity Point.
** ''Kiva'' had [[EvilCounterpart the Bat Fangire]].
** ''Decade'' had Apollo Geist at first, then [[spoiler:Eijiro Hikari/Dr. Death and Narutaki/Colonel Zol in the film]], who are in turn usurped by [[spoiler:[[GoneHorriblyRight the Neo Organism]]. Again.]]
** ''Double'' had [[TheDon Ryubee Sonozaki]][==]/the Terror Dopant. He was the first big bad in a while to be revealed as one in the first episode. Most of the heisei Kamen Rider Big Bads are revealed after the halfway point or in the final arc.
** ''OOO'' had [[MadScientist Dr. Maki]]. Interestingly, he was supposed to just be the big bad for the second arc, and that Ankh was going to be the final villain, but things changed and he became a fully fledged big bad.
** ''Fourze'' had [[EvilTeacher Gamou Mitsuaki]][[spoiler:/Sagittarius]], who heads Amanogawa High School. It is obvious that he has [[RedEyesTakeWarning red eyes]] whenever he wants to.
** ''Wizard'' had Wiseman[[spoiler:, who is really an alter ego of none other than the White Wizard]].
** ''Gaim'' has the Helheim Forest, an invasive species threatening to overtake Earth. There are [[BigBadEnsemble a lot of other villains on the show]] who often take the lead for a time, but everyone on the show is simply trying to either fight against Helheim or take advantage of it.

* ''Series/TheLegendOfDickAndDom'': [[spoiler: The Beastmaster]] is a mysterious entity behind many of the protagonists' setbacks in season two (showing up- without his identity being revealwed- at the end of each episode to punish the villains who failed to stop them). He is revealed as the antagonist for season three.
* ''Series/LegendOfTheSeeker''
** Season 1 has Darken Rahl
** Season 2 has The Keeper
* ''Series/{{Leverage}}'' typically lacks one of these, but in Season 4 we have Victor Dubenich, a former mark out for revenge, who manipulates the events of the season from behind the scenes before stepping into the spotlight in the last two episodes.
* ''Series/{{Lost}}'' had an interesting succession, with the scope of the show panning out to reveal a Bigger Bad.
** Season 1: Didn't seem to have a BigBad originally. The most reoccuring antagonist that season was The Smoke Monster, who seemed more like a rampaging beast, with Ethan being a runner-up, though it's clear he was just a spy [[spoiler:and he's killed by Charlie a few episodes before the finale]], and it's only in the finale that we see other, well, Others, including Tom Friendly, but they only appear in one scene [[spoiler: to kidnap Walt]]. [[spoiler:Though it turns out this season DID have a BigBad, as the Smoke Monster was the BigBad of the entire series]]
** Season 2: The survivors originally assume Mr. Friendly is this, but this is confirmed false and instead an unnamed and unseen leader is hinted at. It isn't until the finale when the leader of the Others is revealed to be Benjamin Linus, aka the man who posed as Henry Gale for much of the season.
** Season 3: Benjamin Linus. [[spoiler: Though hints are thrown at Jacob, the mysterious being the Others worship. Though he is revealed to actually be the BigGood seasons later and never approved of Ben's actions]]
** Season 4: Charles Widmore, though his PsychoForHire Martin Keamy gets more screentime.
** Most of Season 5 skips around with lots of smaller villains, and switching back and forth between Ben and Widmore, until it reveals the true BigBad of Lost: [[spoiler:The Man in Black/The Smoke Monster.]], who finally plays the primary antagonist role in the sixth and final season directly.

* ''Series/TheMentalist'': [[ArchEnemy Red John]] ([[spoiler:Sheriff Thomas [=McAllister=]]]).
* ''Series/{{Merlin}}'' has had several, but notably King Uther Pendragon, and then Morgana, [[spoiler: following Uther's death]]. However, each season had a back-up BigBad for Merlin to face when Uther and Morgana were busy, and because of the show's GreyAndGreyMorality, it could be surprisingly difficult at times (especially in the early seasons) to pin-point who exactly posed the greatest threat.
** Season 1: Nimueh, who is indeed the overall BigBad of the season, being behind most of the problems in Camelot. Uther is also at his most threatening here, though in later seasons he was more of an [[TheAntagonist Antagonist]] than an overt villain.
** Season 2: The most complex season in terms of villainy. Uther mellowed out a bit and Morgause is initially quite justified in most of her actions and beliefs. Morgana goes through her FaceHeelTurn but is still mostly sympathetic and Kilgharrah's RevengeBeforeReason arc is resolved in the finale and never brought up again.[[note]] This complexity is the reason why season two is often cited as the best season.[[/note]]
** Season 3: Morgause, with Morgana as her DragonInChief.
** Season 4: Morgana, with Agravaine de Bois as her [[TheDragon Dragon]] who also served as TheMole in Camelot.
** Season 5: Morgana, and eventually Mordred. Interestingly, Mordred spends the majority of his appearances not evil, but his prophesied betrayal is the series main arc and biggest threat.
** King Odin was also a major threat in the series, [[spoiler: until he and Camelot made peace in the final season]].
* ''Series/MythQuest'': Gorgos is a trickster god who tries to change any myth he's trapped in. He was released by Matt Bellows, and his children Alex and Cleo try to rescue their father while preventing Gorgos from changing mythology.
* ''Series/Monster High'': The antagonists change at various times throughout the webseries.
** Cleo de Nile was the main antagonist for season 1.
** Spectra Vondergeist and Toralei Stripe were the main antagonists for season 2.
** Season 3 had no direct antagonist as most episodes usually contain a new plot.

* ''{{Neighbours}}'':
** Charles Durham in the 1985 season, a VillainWithGoodPublicity who made repeated attempts to obtain an incriminating casette tape from Terri, threatening her and those around her. He was shot dead in a confrontation with Terri in the final week of the season.
** In late 2005 and for the first half of 2006, Robert Robinson filled this role, making several attempts on the lives of his father and sister while disguised as his triplet brother.
* ''Series/{{Nikita}}'' had Percy in season 1. For the first half of season 2 he was imprisoned inside Division and replaced as BigBad by his {{Dragon|Ascendant}}, Amanda, but he eventually turned the tables on her and reclaimed the BigBad mantle. [[spoiler:He gets killed at the end of season.]]
** Amanda retakes the BigBad mantle in season 3, undergoing a campaign of revenge against Nikita [[spoiler: and the reformed Division]].

* ''Series/OnceUponATime'':
** Season 1: Regina Mills, the Evil Queen
** Season 2a: Cora Mills, the Queen of Hearts
** Season 2b: A BigBadDuumvirate of Tamara and Greg
** Season 3a: Peter Pan[[spoiler:, who was the BiggerBad to Tamara and Greg all along]]
** Season 3b: Zelena Mills, the Wicked Witch of the West
** Season 4a: Ingrid, the Snow Queen
** Season 4b: Mr. Gold, along with Cruella, Ursula and Maleficent
* ''Series/OnceUponATimeInWonderland'' has a BigBadDuumvirate of Jafar and the Red Queen, Anastasia Tremaine. Though it's a [[TeethClenchedTeamwork tenuous]] alliance, especially what with Jafar seeing himself as superior. It's ultimately broken when [[spoiler: the Red Queen pulls a HeelFaceTurn while Jafar destroys all her assets, leaving him as the sole BigBad.]]
* ''Series/OneTreeHill'' usually doesn't have a straightforward big bad after the first few seasons. However, certain villains impact the show more than others, such as Katie, whose [[spoiler:shooting]] of Clay and Quinn impacted them even in the following season.
** Season 1: Dan Scott
** Season 2: Dan Scott
** Season 3: Dan Scott and Rachel Gatina
** Season 4: Dan Scott
** Season 5: Carrie
** Season 6: Carrie
** Season 7A: Rachel Gatina
** Season 7B: Katie Ryan
** Season 8: Katie Ryan
* ''Series/OobiAtWork'': Sue Worrellman, a red-eyed villain, is the cause of all misery for Oobi and his co-workers.
* ''Series/OrangeIsTheNewBlack'':
** Season 1: Tiffany "Pensatucky" Doggett
** Season 2: Vee
* ''Series/TheOriginals'': The first season has a major [[BigBadEnsemble mess]] of it. Initially it appears to be Marcel or Klaus, [[spoiler: and then [[StarterVillain Sophie Deveraux]] is revealed to be playing them both, then Sophie is killed and Celeste seems to take the role, but she proves to be DiscOneFinalBoss. In the last episodes of the season the BigBadEnsemble is in full effect with Genevieve, who becomes the leader of the witches after Celeste's death, Monique, who acts as her DragonInChief, Franesca Correa, who pretending to lead the humans but is in fact setting up the werewolves to take over New Orlens, and Mikael, who spends his time up until the season finale preparing for his resurrection. Ultimately Esther is revealed to be behind everything the witches where up to, leading to her own resurrection at the end of the season.]]

* ''Series/{{Passions}}'': [[DiabolicalMastermind Alistair Crane]].
* ''Franchise/PowerRangers''. This might take a while:
** ''Series/MightyMorphinPowerRangers'': Rita Repulsa, then Lord Zedd, then Rita and Zedd combined, then Rita's dad Master Vile, then Rita and Zedd combined again.
** ''Film/MightyMorphinPowerRangersTheMovie'': Ivan Ooze.
** ''Series/PowerRangersZeo'': King Mondo, even during a time when he [[spoiler:was dead, but everyone knew he would get better.]] During that time, the role of BigBad went to Louie Kaboom, who was later replaced by Prince Gasket and Archerina, before King Mondo came back to resume command for the remainder of the series.
** ''Series/PowerRangersTurbo'': Divatox.
** ''Series/PowerRangersInSpace'': Dark Specter, who was revealed to be in control of all of the above. Intended to be the final villain, and remains the biggest bad seen on the show to this day. Alternately, Dark Specter is the BiggerBad while the regular BigBad position goes to Astronema, the one in charge of the forces that harassed the Space Rangers on a regular basis.
** ''Series/PowerRangersLostGalaxy'': Scorpius, later succeeded by his daughter Trakeena. Captain Mutiny takes over the role for an arc, but Trakeena proves to be EvilerThanThou when she kills Mutiny.
** ''Series/PowerRangersLightspeedRescue'': Queen Bansheera.
** ''Series/PowerRangersTimeForce'': Ransik (redeemed, a rarity for these villains).
** ''Series/PowerRangersWildForce'': Master Org, usurped by Mandilok, then Master Org again.
** ''Series/PowerRangersNinjaStorm'': Lothor.
** ''Series/PowerRangersDinoThunder'': Mesogog.
** ''Series/PowerRangersSPD'': Emperor Gruumm.
** ''Series/PowerRangersMysticForce'': TheMaster was the big one, but there was a series of villains under him that took command in his stead: Morticon, Imperious, and Sculpin. Like ''In Space,'' it may be that the SealedEvilInACan Master is the BiggerBad while each arc's DragonInChief is the BigBad.
** ''Series/PowerRangersOperationOverdrive'': a BigBadEnsemble with Flurious, Moltor, Kamdor, and the Fearcats; opposed not only to the Rangers but also to one another. [[spoiler: Flurious outlives them all and eventually gains the crown and jewels right before the final battle.]]
** ''Series/PowerRangersJungleFury'': Dai Shi.
** ''Series/PowerRangersRPM'': The Venjix computer virus.
** ''Series/PowerRangersSamurai'': Master Xandred, lord of the Nighloks.
** ''Series/PowerRangersMegaforce'': Admiral Malkor of the Warstar Armada in the first season, though Vrak got more screentime as the highly competent DragonInChief. In the second season, Malkor's boss (and ''Prince'' Vrak's brother) Prince Vekar shows up with the ''rest'' of the Armada. When he's defeated Vrak briefly returns, then Emperor Mavro becomes the final villain.
** ''Series/PowerRangersDinoCharge:'' Sledge.
* ''Series/PrettyLittleLiars'' has [[TheGhost "A"]] as the overall main enemy on all season so far, but there are sometimes other characters who also take on the role of the BigBad.
** Season 1: Ian Thomas
** Season 2: Mona Vanderwaal
** Season 3: Red Coat
** Season 4: Jessica Dilaurentis
** Season 5: Charles Dilaurentis
** The series also usually has "Little Bads" aka BigBad's during the first half of the season. The first season has Mona. The second arguably has Jenna and Garrett, but Mona's here, too. The third season has Nate St. Germain. The fourth season has Red Coat and there's also Ezra Fitz, who becomes the BigBad in episode 12 and remains so until episode 20. The fifth season has Mona for the first part and Alison for the rest.
* ''{{Series/Primeval}}''
** Season 1: The Future Predator.
** Season 2: Oliver Leek.
** Season 3: Helen Cutter.
** Season 4: Ethan Dobrowski/[[spoiler: Patrick Quinn]]
** Season 5: Philip Burton.
* ''Series/PrisonBreak'':
** Vice-President Caroline Reynolds served as the main antagonist for the first and second seasons. Then, she [[spoiler: quits her position and exits the story completely]] in order to reveal [[TheManBehindTheMan the true Big Bad]]: General Krantz.
** Season 4, however, has a BigBadDuumvirate between General Krantz and Christina [[spoiler: Scofield.]]

* ''Series/{{Revenge}}'': For most of season 1, [[CorruptCorporateExecutive Conrad]] and [[EvilMatriarch Victoria]] Grayson, being at the center of the conspiracy to frame David Clarke for their own crimes, hold this position by default. However, by the end of the season it's clear they were ultimately just pawns of the EvilerThanThou [[NebulousEvilOrganization Americon Initiative]], who now serve as the BiggerBad of the series. As of a few episodes into season 2, the Initiative seems to be taking more active steps and moving down into the actual BigBad role. Then the season finale reveals that [[spoiler: the Initiative is just a cover for a group of {{Corrupt Corporate Executive}}s making money from their acts of terror... and Conrad is now in their inner circle]]. This definitely puts Conrad right back into the role of BigBad, pushing out even the [[EvenEvilHasStandards horrified]] Victoria.
** As of Season 4, Victoria splits the role with Malcolm Black for the first half. The second half seems to be building up with a scorned and mourning Margaux preparing to take on Emily.
* ''Series/{{Revolution}}'': General Sebastian "Bass" Monroe, initially. However, it gets more complicated as the first season goes on. First, it becomes a BigBadEnsemble when [[WellIntentionedExtremist Randall Flynn]] is introduced running his own scheme in [[Recap/RevolutionS1E7TheChildrensCrusade episode 7]]. In [[Recap/RevolutionS1E11TheStand episode 11]], it becomes a loose BigBadDuumvirate when they team up halfway through the season (with it clear they're only using each other). Finally, it goes back to being an Ensemble in the [[Recap/RevolutionS1E20TheDarkTower season finale]] as [[spoiler: [[TheStarscream Major Neville]] starts a coup against Monroe, while Randall commits suicide...only to turn out to have been [[TheManBehindTheMan working for]] the [[GovernmentInExile in-exile]] US President.]]
** The Ensemble gets streamlined in Season 2, as the Patriots and their leader [[PresidentEvil President Davis]] prove to be EvilerThanThou on a massive scale, leading to them becoming the dominant threat. Though that said, Monroe and Neville are both running their own schemes, and then there's the ultimate WildCard that is [[spoiler: the now-sentient [[AIIsACrapshoot nanotech]]]].

* ''Series/TheSarahJaneAdventures''
** Series 1: The Slitheen, but most notably in a surprise twist, [[spoiler: Mr Smith]].
** Series 2: Mrs Wormwood.
** Series 3 and 4: No real Big Bad: the Blathereen and Ruby White function as the [[FinalBoss villains]] of the respective season finales.
** Series 5: [[WhatCouldHaveBeen Intended]] to be the Trickster, slowly possessing Sky in order to become corporeal, but the [[CharacterOutlivesActor death of Elisabeth Sladen]] meant the show was cancelled before this could be revealed.
* ''Series/SaulOfTheMoleMen'': Otnip.
* ''Series/TheSavageEye'': The British Empire and the Catholic Church, as this is a series about Irish culture and why it is like it is.
* ''Series/{{Scandal}}'': The first season didn't seem to have one, but [[spoiler: Billy Chambers]] like qualifies. The second season, however, establishes [[spoiler: Hollis]] as this, due to him having 7 people killed and framing someone for it to cover up vote tampering, and having the President himself shot and framing Huck for it! [[spoiler: However, it turns out that he didn't have the President shot, Judge Verna did that]].
* ''Series/SeaPatrol''
** Season 1: Rick Gallagher
** Season 2: Ray Walsman
** Seaaon 3: Campbell Fulton
* ''Series/TheSecretCircle'': BigBadDuumvirate of [[ScaryBlackMan Eben]] and [[ArchnemesisDad John Blackwell]].
* ''Series/{{Sherlock}}''
** Seasons 1 and 2: Jim Moriarty.
** Season 3: Charles Augustum Magnussen.
* ''Series/TheShield'' had one in most of it's seasons:
** Season 1: Ben Gilroy
** Season 2: Armadillo [[spoiler: for the first half of the season or so.]]
** Season 3: The Armenian mob and Margos
** Season 4: Antwon Mitchell
** Season 5: This season plays around with this a bit with Jon Kavanaugh who is more of an AntiVillain [[spoiler: until his desire to take down Vic drives him to become a FallenHero.]]
** Season 6: There isn't really one this season but it does set up some Big Bads in waiting in the form of Pezuela, the Armenians and [[spoiler: Shane.]]
** Season 7: Has a BigBadEnsemble with Pezuela, the Cartel, the Armenians, Lloyd and [[spoiler: Shane]].
* ''Series/SleepyHollow'' has [[DemonLordsAndArchdevils Moloch]], the demon who's attempting to begin the Apocalypse for his own ends.
* ''Series/{{Sliders}}'' after its premise was changed:
** Seasons 1 & 2: Original premise, no Big Bads.
** Season 3: Colonel Angus Rickman.
** Season 4: The Kromaggs.
** Season 5: Doctor Oberon Geiger.
* ''Series/{{Smallville}}'' initially has [[MagnificentBastard Lionel Luthor]] as the main antagonist of Seasons 1-3, although other secondary antagonists, like reporter [[{{Paparazzi}} Roger Nixon]], [[SuperPoweredEvilSide Kal]] and [[GoodIsNotNice Jor-El]] also took a stab at this role in each season respectively. Following Lionel's defeat and subsequent HeelFaceTurn, the situation got a lot more complicated, but played out more or less as follows:
** Season 4: [[EvilMatriarch Genevieve Teague]], with [[spoiler: [[MommasBoy her son]] [[MadeOfIron Jason]] as TheDragon]] and [[WickedWitch Margaret Isobel Thoreaux]] as her [[BigBadEnsemble archrival]].
** Season 5: [[RoboticPsychopath Brainiac]] with [[spoiler: [[SealedEvilInACan General Zod]]]] as the BiggerBad he was seeking to unleash.
** Season 6: LexLuthor. Yeah. the [[MonsterOfTheWeek Zoners]] are out there, and [[EvilTwin Bizzarro]]'s waiting in the wings, but Lex is TheHeavy for the season, and is behind almost every problem in series.
** Season 7: [[ManipulativeBastard Lex]] and Brainiac form a BigBadDuumvirate.
** Season 8: The most complicated season, with a huge BigBadEnsemble, including [[TheBaroness Tess Mercer]], [[TheManBehindTheMan Faora]], [[spoiler:[[EvilCripple Lex]]]], and DiscOneFinalBoss [[OmnicidalManiac Brainiac]] all vying for the role. All of them have their own agendas, and the [[{{Chessmaster}} complicated plans]] to back it up. Yet when [[EvilerThanThou the smoke clears]] it's SerialKiller and {{Antihero}} [[DrivenToVillainy Davis Bloome]] and his SuperpoweredEvilSide [[PersonOfMassDestruction Doomsday]] who step up to the plate as TheHeavy, providing most of the drama in the season's latter half, and serving as the FinalBoss to boot.
** Season 9: [[MajorlyAwesome Major Zod]] and his cloned Kandorian army, with [[MisanthropeSupreme Tess]] as a sometimes ally, and [[GovernmentConspiracy Checkmate]] trying to stop him.
** Season 10: {{Darkseid}}, with [[CoDragons Granny Goodness, Desaad, and Glorious Godfrey]] doing his dirty work. Lots of others [[BigBadWannabe try for this role]], but compared to [[UltimateEvil Darkseid]]'s ominous presence they just don't cut it. See BigBadEnsemble for the breakdown though.
** The Season 11 continuation comics have Lex back and causing trouble again on a mostly regular basis, but also have a story arc dealing with the larger threat of [[spoiler: [[CountdownToFinalCrisis the]] [[FinalCrisis Monitors]]]], who seek to impose order by [[OmnicidalManiac destroying all life]] [[spoiler: and have already succeeded with Earth-2.]]
* Season 1 of ''Series/SonsOfAnarchy'' doesn't really have one.
** Season 2: Ethan Zobelle
** Season 3: James "Jimmy O" O'Phelan and Agent Stahl
** Season 4: The Cartel [[spoiler: is a subversion, the real BigBad is Clay Morrow]]
** Season 5: Damon Pope [[spoiler: is set up as this initially, but takes a back seat for much of the season while Clay tries to plot against Jax again before Pope returns to prominence again at the end of the season. So... BigBadEnsemble?]]
** Season 6: Lee Toric is introduced at the end of season 5 and set up to be the big bad of season 6 [[spoiler: until Otto kills him four episodes in. After that it's sort of a toss up between the Irish and Tyne Patterson.]]
** Season 7: [[spoiler: Gemma.]]
* ''Series/TheSopranos'':
** Season 1: Uncle Junior [[spoiler: and Livia Soprano]]
** Season 2: Richie Aprile [[spoiler: is a subversion and ends up being a DiscOneFinalBoss.]]
** Seasons 3 and 4: Ralph Cifaretto
** Season 6: Phil Leotardo
* ''Series/SpartacusBloodAndSand'':
** Blood and Sand: Batiatus
** Gods of the Arena: Tullius
** Vengeance: Glaber
** War of the Damned: Crassus
* ''Series/StargateAtlantis'': Although the general premise of the series is the battle against the Wraith, even after four and a half seasons no individual character seems to have emerged as a specific Big Bad. There are currently several prominent ''candidates'', including: [[TheStarscream Rogue Wraith]] and EvilGenius Michael; Oberoth (the leader of the EvilerThanThou Replicators); and AffablyEvil AntiVillain Todd, who seems to be making a power play for Supreme Wraith Leader. Had the series continued, it looks as though the [[spoiler:Vanyir]] would have been the next adversary.
* ''Series/StargateSG1'' has a series of Big Bads, although there are often long stretches in the middle seasons where they becomes fairly uninvolved with the plot.
** Season 1 to 4: Apophis / Sokar / [[BackFromTheDead Apophis again]]
** Seasons 5 to 8: Anubis
*** Late Season 8: Replicator Carter (in addition to Anubis)
** Season 9 to 10 and ''The Ark Of Truth'': The Ori / Adria
** ''Stargate: Continuum'': Ba'al, the final(?) villain, ascending to Big Bad status after 6 seasons as TheStarscream.
* ''Series/StarTrekEnterprise'':
** Silik is almost the Big Bad of the first two seasons, but since he's being controlled by [[FanNickname Future-Guy]], he fell short. The whole story is never really concluded because the [[StoryArc Temporal Cold War]] doesn't really go anywhere and wasn't very popular.
** The Xindi story of season 3 spent most of the time trying to figure out who among the Xindi Council was reasonable and who wanted to blow up Earth no matter what, or the Big Bad. Eventually [[spoiler:every Xindi species but the Reptilians started to side with the ''Enterprise'' instead of the [[ScaryDogmaticAliens Sphere-Builders]].]]
** The Romulans begin to take on this role in season 4, working to undermine the alliances that would lead to the formation of the Federation. If the series had continued, the storyline would eventually have led to the Romulan War mentioned in the original series.
* ''Series/StarTrekDeepSpaceNine'' actually manages a couple:
** Gul Dukat is ''Deep Space Nine'''s premier Big Bad. He starts out as a fairly bog-standard antagonist, becomes a sympathetic character (an AntiVillain if not AntiHero), before crossing the MoralEventHorizon and [[spoiler: becoming, effectively, the antichrist.]] He's also the only recurring villain in Star Trek history to [[spoiler: kill off a main character.]]
** The Female Changeling serves as the face of the Founders (the leaders of The Dominion), although [[TheDragon Weyoun]] has a fair amount of face time representing The Dominion as well.
* ''Series/StarTrekTheNextGeneration'' has Q, although he becomes [[VillainDecay less and less bad]] as the series goes on and ends up as more of a [[TheTrickster Trickster]] figure. Commander Sela seems to be behind everything the Romulans are doing in late Season 4/early Season 5, and Lore [[BigBadWannabe has a go]] by setting himself up as the leader of the Borg.
* ''Series/StarTrekVoyager'' has two {{Big Bad}}s over the course of the series:
** For the first two seasons, the ship is hounded by a sect of the Kazon, although the exact Big Bad is debatable: their leader is First Maje Jal Culluh, but TheMole, [[spoiler:Seska]], has center stage much more often, even going on to menace the heroes a couple more times post-mortem.
** A few seasons later, when the Borg take over as Voyager's main adversaries, the role of Big Bad goes to the one controlling them (or the one personifying them, or whatever is going on there), the Borg Queen.
* ''Series/{{Suits}}'':
** Season 1: No real big bads, although most fans consider Trevor this due to him [[spoiler: telling Jessica Mike's DarkSecret in the finale]] and due to being overall [[PoisonousFriend a really terrible best friend]].
** Season 2: Daniel Hardman.
** Season 3: Cameron Dennis and [[spoiler: Stephen Huntley.]]
* ''Series/{{Supernatural}}'''s overall Big Bad has actually always been [[spoiler: Lucifer]], who takes the stage in Season Five. The character who did nearly every action for the entire plan was The Yellow-Eyed Demon aka Azazel, who served as Big Bad in Seasons One and Two. Lilith served the role in Seasons Three and Four.
** In [[PostScriptSeason season 6]], the position of new BigBad was up in the air for most of the season, with the best contenders being either Crowley, the new King of Hell, or Raphael, the leader of the angels who want [[spoiler: to restart the Apocalypse]]. Midway through the season, however, Crowley [[spoiler: [[FakingTheDead faked his death]]]] and we were introduced to an [[EldritchAbomination entity]] known as the "Mother of All", who seemed set to take up the role. But then, [[spoiler: Dean killed her]], and soon after it was revealed that Crowley was working with [[spoiler: ''Castiel'']] of all people in order to take over Purgatory. So, it looked like they were going to [[BigBadDuumvirate jointly]] be the BigBad of the season. But then in the season finale, [[spoiler: Castiel]] tried to cut Crowley out of the deal, so he retaliated by [[VillainTeamUp teaming up]] with Raphael, making it look like they'd be the {{Big Bad}}s together after all, only for [[spoiler: Castiel to OutGambit them at the last minute, absorb the souls of Purgatory and [[AGodAmI declare himself the new God]].]] Guess he was the true BigBad of the season after all.
** In the very first episode of season 7, [[spoiler: Castiel gives up his new godlike powers, having realized his mistake -- but before he can truly redeem himself]], he is [[BaitAndSwitchBoss replaced by]] the ''true'' BigBad -- [[spoiler: the Leviathans]]. Thus, for most of the season, our heroes are on the run from [[spoiler: a species of monsters who are older than angels with no known weaknesses or vulnerabilities]] -- until [[spoiler: Castiel [[BackFromTheDead turns out to be alive]], heals Sam's mental trauma by taking it onto himself, and recovers enough to help them decode the Word of God, which reveals how to kill the bastards for good]].
** For Season 8 it's a BigBadEnsemble between Crowley and Naomi, the leader of Heaven's [[TheMenInBlack Men In Black]]. Though the last couple of episodes bring in Abaddon (the last [[EliteMooks Knight of Hell]]) as a potential [[TheStarscream Starscream]] to Crowley [[spoiler: while the season finale has Naomi have a HeelRealization, only to be [[RedemptionEqualsDeath killed]] by [[EvilAllAlong Metatron]], who casts a spell to banish ''all'' angels from Heaven.]]
** Season 9 builds on the previous season's Ensemble as it stood at the end of the season: [[KnightTemplar Bartholomew]] and [[TheSociopath Malachi]] emerge as the leaders of the civil war amongst the [[spoiler: fallen]] angels, with [[spoiler: Metatron]] -- now in full AGodAmI mode -- also recruiting in order to secure his own position [[spoiler: as sole ruler of Heaven]]. Meanwhile, Abbadon is continuing to try and usurp Crowley's position, while Crowley himself now a WildCard.

** ''Series/ChoujuuSentaiLiveman'': Great Professor Bias
** ''Series/KousokuSentaiTurboranger'': Great Violent Demon Emperor Lagorn
** ''Series/ChikyuuSentaiFiveman'': Galactic Empress Meadow. [[spoiler: But she was dead the whole time and never evil. The real villain is the ship, Vulgyre, who transforms into Galactic Super Beast Vulgyre.]]
** ''Series/ChoujinSentaiJetman'': Technically didn't have one since the four major villains were competing to see who could kill the Jetmen first for the position, but Count Radiguet is the closest.
*** Jetman actually subverts this in that the BigBad is actually Empress Juza, though she just lasts 2 episodes and Radiguet takes over being the show's technical BigBad (he was formerly the closest for Juza's [[TheDragon Dragon]])
*** Tranza also manages to usurp the BigBad position for several episodes, until Radiguet reclaims that position.
** ''Series/KyoryuSentaiZyuranger'': Bandora, until BiggerBad Dai Satan takes over at the end.
** ''Series/GoseiSentaiDairanger'': Emperor Gorma XV [[spoiler:or so it would seem. Turns out he and all the Gorma Tribe higher-ups are actually golems created by Colonel Shadam, apparently TheDragon, who eventually just takes over for real and becomes Emperor Gorma ''XVI'']]
** ''Series/NinjaSentaiKakuranger'': Daimaou
** ''Series/ChourikiSentaiOhranger'': Emperor Bacchus Wrath, later he is killed off and replaced by his son, Kaiser Buldont

** ''Series/SeijuuSentaiGingaman'': Captain Zahab
** ''Series/RescueSentaiGoGoFive'': Grand Witch Grandiene (also an EvilMatriarch)
** ''Series/MiraiSentaiTimeranger'': At first seems to be Don Dolnero, later revealed to actually be [[spoiler:Captain Ryuya.]]
** ''Series/HyakujuuSentaiGaoranger'': The Org Master, with the Highness Duke Orgs Shuten, Ura, and Rasetsu being the [[DragonInChief Dragons in Chief]] so much that they pretty much count as the Big Bads for an arc each. [[spoiler:Unsurprisingly, the Org Master is revealed to be an unsentient figurehead with the Highness Dukes as the actual Big Bads. They soon merge into the final Big Bad: Ultimate Org Senki.]] For the MilestoneCelebration movie, Lost Org Rakushaasa fills the role.
** ''Series/NinpuuSentaiHurricaneger'': Boss Tau Zanto
** ''Series/BakuryuuSentaiAbaranger'': Dezmosauria
** ''Series/TokusouSentaiDekaranger'': None. All the villains are independent. The closest would be the sole recurring baddie Agent Abrella, who sells them their weapons. [[spoiler: Though he does seem to take that role well when he executes the AllYourBaseAreBelongToUs plan.]]
** ''Series/MahouSentaiMagiranger'': [[EldritchAbomination Absolute God N Ma.]]
*** Though N Ma acts like a BiggerBad until the very end, so his three [[DragonInChief Dragons In Chief]], Braken, Meemy, and Dagon, would also qualify as the BigBad of one arc.
** ''Series/GoGoSentaiBoukenger'': High Priest Gaja of the Godom Civilization; Creator King Ryuuwon of the Jaryuu Clan; Gekkou of Illusions of the Dark Shadow ninja clan; and Gai and Rei, the last remaining members of the Ashu Tribe. These four are not only against the Boukenger, but also each other, in the quest for [[MacGuffin the Precious]]. [[spoiler:Gaja is the final Big Bad, in case you were curious.]] For this MilestoneCelebration movie, Time Demon Chaos is the Big Bad.
** ''Series/JukenSentaiGekiranger'': Rio. [[spoiler: Who was manipulated by Long, the Infernal Dragon. Upon learning this, Rio and his Dragon, Mele, perform Heel Face Turns to help fight Long.]]
** ''Series/EngineSentaiGoOnger'': The three Gaiark Ministers, then [[spoiler:Kirezky]], and finally their boss shows up near the end: [[spoiler: Prime Minister Yogoshimacritein.]]
** ''Series/SamuraiSentaiShinkenger'': Chimatsuri Doukoku
** ''Series/TensouSentaiGoseiger'': Great King Mons Drake, Makuin of the Blob, and Emperor Robogog the 10th in succession. [[spoiler: But in the end it turns out the biggest threat is Bladerun/Buredoran, a.k.a. Brajira of the Messiah, a fallen angel]].
** ''Series/KaizokuSentaiGokaiger'': Prince Warz Gill, then [[spoiler:Emperor Akdos Gill]]. For the main MilestoneCelebration movie, which doubles as the ''Goseiger'' crossover, the Black Cross Fuhrer returns as the Black Cross King.
** ''Series/TokumeiSentaiGobusters'': Messiah. [[spoiler: He is destroyed in Episode 30, but Enter survived and is acting as the Big Bad while trying to recreate Messiah. Then Escape tries to kill him, succeeds in recreating Messiah, and is [[YouHaveOutlivedYourUsefulness reintegrated into him]]... only for Messiah to die again and Enter to have survived.]]
** ''Series/ZyudenSentaiKyoryuger'': Despite serving a larger evil, Many Faced High Priest Chaos initially stood out as the greater threat, due to Deboss being incapacitated. [[spoiler:Until they succeeded in fully resurrecting Deboss, who took over as the Big Bad for the remainder of the season.]]
** ''Series/HikoninSentaiAkibaranger'': Malshina was set up to be this at first, but behind her there is [[spoiler: Dr. Z, the Professor's father, and creator of the Rangers' tech, which was ''created'' as a way to cause the simulated monsters and such to leak into reality.]] Except ''then'' the MindScrew takes over and by the end of the series the ''true'' BigBad is [[spoiler:''an AuthorAvatar of the Toei executive staff''.]]
*** In season two, season one is canon only in BroadStrokes and Malshina has a ManBehindTheMan, General Pain, but he can hardly be arsed to do any real villainy and she has to keep bugging him to make monsters [[spoiler: until episode 7. However, it's later revealed that Malshina is the real Big Bad this time and steals the abilities of both General Pain and Saburo Hatte, and the Bigger Bad this time is Prism Ace, an Ultraman Expy.]]

** Season 4: Kate Argent and Peter Hale.
* ''Series/{{Torchwood}}'':
** Season 1: [[SealedEvilInACan Abaddon]], though he might qualify more as a FinalBoss, with the majority of the work done by his DragonInChief [[ManipulativeBastard Billis Manger]].
** Series 2: [[CainAndAbel Gray]]
** [[Series/TorchwoodChildrenOfEarth Series 3]]: [[StarfishAliens The 456]]
** [[Series/TorchwoodMiracleDay Series 4]]: [[AncientConspiracy The Three Families]]

** Seasons 9-12: Rose occasionally filled the role, but it was actually revealed in the finale to be an InVerse [[spoiler: Chuck Lorre]].

* Within the ''Franchise/UltraSeries'', any opponent that's much stronger than usual typically qualifies as this.
* ''Series/{{Underbelly}}''
** Carl Williams and Mick Gatto.
* ''Series/UnderbellyATaleOfTwoCities'': Terry Clark and Bob Trimbole
* ''Series/UnderTheDome'': While the overall BigBad is the [[BiggerBad Dome]] and [[TheHeavy Big Jim Rennie]], each season also has other BigBads. Especially seeing as how both Big Jim and the Dome continue being an on/off villain.
** Season 1: Maxine Seagrave
** Season 2: The first half has a BigBadDuumvirate between Big Jim Rennie and Rebecca Pine, who devise a plan to release a virus, along with Sam Verdreaux, who kills [[spoiler: Angie]] and attempts to kill others. But in the second half, Sam and Rebecca redeem themselves and Big Jim continues being an on/off villain, while the Dome takes the role of the seasons true BigBad.
* The ''Series/UpstairsDownstairs'' 2010 revival has one, rather unusually for a non-speculative FamilyDrama: [[spoiler: Persie, a Fascist and Nazi spy who wrecks her sister's marriage, nearly destroys her brother-in-law's career, nearly kills Beryl, and otherwise causes most of the trouble on the show. She's more pathetic than menacing, and the chaos she leaves in her wake is haphazard rather than planned, but she's a thoroughly destructive presence.]]

* ''Series/TheVampireDiaries'' has [[AxCrazy Klaus]] [[ImmortalityImmorality Mikaelson]] as either a BigBad or TheHeavy. Although most of the enemies they faced were his enemies as well, they had ideas of how to go about opposing him that were incompatible with the interests of the main cast.
** Season One has the Founders' Council, led by Mayor Richard Lockwood. However, the more direct threat is John Gilbert, who acts as the DragonInChief and TheHeavy to both the Council and [[TheManBehindTheMan Katherine Pierce]], respectively.
** Season Two starts with [[FemmeFatale Katherine]], but halfway through it, Klaus officially steps up to the BigBad title.
** Season Three has [[spoiler: Klaus' mother [[EvilMatriarch Esther]]]] and [[spoiler: [[FallenHero Alaric]], who developed a psychotic alter ego]].
** Season Four has [[ShroudedInMyth Silas]], who [[CurbStompBattle pwns]] ''Klaus'' of all people and uses Atticus Shane as TheDragon before that.
** Season Five has a BigBadEnsemble of [[MirrorSelf Silas]], [[PsychoExGirlfriend Qetsiyah]], [[MadScientist Wes Maxfield]], and [[ItsAllAboutMe Katherine]]. However, as of Episode Fifteen, [[spoiler: all four of them are dead]], leaving [[NoNonsenseNemesis Markos]] to step up as the BigBad and FinalBoss.
** Season Six has [[TheSociopath Malachai]] [[FauxAffablyEvil "Kai"]] [[BlackSheep Parker]], with the Gemini Coven who opposed Markos and the Travelers serving as the BiggerBad due to their twin-merging ritual that led to Kai's birth and subsequent murderous resentment of his siblings.
* ''Series/VeronicaMars'' uses the BigBad in its first two seasons where there is a overarching mystery plotline throughout the entire season. Usually, the BigBad is the person who performs the corresponding crime.
** Season one has a few decoys, such as Jake Kane, Celeste Kane, Abel Koontz and Clarence Wiedman, but later it is revealed that Lily Kane's killer was actually [[spoiler: Aaron Echolls]].
** Season two has a decoy BigBad, [[spoiler: Woody Goodman]], but later it is revealed that the bus crush killer was [[spoiler: Cassidy Casablancas]].
*** [[spoiler: Cassidy should probably be considered the biggest Big Bad of the show. While Aaron's murder of Lily was changing Veronica's life, Cassidy's raping Veronica was the event that changed ''her'' forever and has [[KarmaHoudini gotten off scott free]] until his last appearance. Plus, he's the only villain to outsmart Veronica]].

* ''Series/TheWalkingDead'':
** Season 1: [[TheUndead The walkers]]
** Season 2: [[spoiler: [[FaceHeelTurn Shane Walsh]]]], eventually, after SlowlySlippingIntoEvil over the course of series.
** Season 3: [[EvilOverlord Philip Blake aka The Governor]].
** Season 4: The first half has [[ThePlague The Flu]] and [[spoiler: [[HesBack The Governor]]]].
* ''Series/{{Warehouse 13}}'':
** Season 1: [[MagnificentBastard James McPhearson]], who wants to steal Artifacts and sell them to the highest bidder, and also [[spoiler: invoke a StartOfDarkness in his former friend Artie]].
** Season 2: [[WoobieDestroyerOfWorlds H.G. Wells]], of all people, who spends the whole season trying to convince the Warehouse agents otherwise, before stabbing them in the back in order to [[spoiler: use an Artifact WMD to begin a new ice age]].
** Season 3: [[EvilCripple Walter Sykes]], who wants to kill the Regents and destroy the Warehouse as revenge for [[spoiler: the Regents stealing an Artifact from him that let him walk]].
** Season 4.0: [[KnightTemplar Brother Adrian]], who wants Artie to undo the [[ResetButton using of the Astrolabe]] at the beginning of the season. [[spoiler: Then it turns out that the "Adrian" he's been dealing with is actually his own EnemyWithin, which eventually performs a SplitPersonalityTakeover.]]
** Season 4.5: At first, it appears to be [[TheAgeless Charlotte/the Countess de St. Germain]], who seems to be manipulating the Warehouse in a revenge scheme against her husband. However, a few episodes before the finale, her backstory is revealed, making her [[JerkassWoobie sympathetic]], before she mistakenly [[SealedEvilInACan releases]] [[spoiler: [[MadScientist Paracelsus]]]], who proves to be EvilerThanThou.
** Season 5: Technically has [[spoiler: the version of Benedict Valda from the AlternateTimeline [[MakeWrongWhatOnceWentRight created by Paracelsus]]]], but due to the [[WrapItUp shortened nature of the season]], he's only in two episodes, and is only the [[DragonAscendant main threat]] in the second appearance.
* ''Series/WhiteCollar'':
** Season 1: Garrett Fowler.
** Season 2: Vincent Adler.
** Season 3: Matthew Keller (first half) and Philip Kramer (second half).
** Season 4: Senator Terrence Pratt
** Season 5: Curtis Hagen was this for the majority of the season, until [[spoiler: Rebecca Lowe]] steps up as the man behind the mask and the real big bad.
* ''Series/TheWildWildWest'': DiabolicalMastermind Dr. Miguelito Loveless.

** Season One: [[BloodKnight Avon Barksdale.]]

** Season Three: [[MagnificentBastard Stringer Bell.]]
** Seasons Four and Five: [[TheSociopath Marlo Stanfield.]]
* Wrestling/{{WWE}} has owner/chairman VinceMcMahon as it's BigBad. It started when he pulled a FaceHeelTurn as a result of the MontrealScrewjob, in which he became the "Mr. [=McMahon=]" character, an evil dictator-like boss. Like everyone else he's goes through the HeelFaceRevolvingDoor.

* ''Series/XenaWarriorPrincess'' had Ares, Callisto, Caesar, Alti, Dahak and the Olympian gods. Xena may not follow the Seasonal Big Bad formula, but the major villains in the series are all recurring, and (with the exception of Ares and Alti) all follow some form of a linear character arc.
* ''Series/TheXFiles'' generally had a large amorphous government conspiracy as the Big Bad, and the ambiguously described hostile alien race planning to colonize Earth. The former was largely represented by the Syndicate (its most notable member being the Smoking Man), and the latter by the shapeshifting bounty hunter (seasons 2-8) and by the metallic super soldiers (season 9).
