"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 Big Bad is the one who turns out to be behind several other seemingly independent threats.
----
* While the ''[[WesternAnimation/AdventuresOfTheGalaxyRangers Galaxy Rangers]]'' had an extensive RoguesGallery for a cartoon of TheEighties, the one who ruled them all was [[GodSaveUsFromTheQueen The Queen of the Crown]]. Mass genocide? Check. Enslaving a planet and putting the inhabitants under concentration camp conditions? Check. [[DefaceOfTheMoon blowing a chunk out of Earth's Moon]] just to prove a point and demand 5000 human lives as tribute? Check. Mash her prisoners down for LifeEnergy, and use the resulting SoulJar [[PoweredByAForsakenChild to power a high-end mook?]] Check. Sends the wife of the one of the heroes to a FateWorseThanDeath? Check. Casual MindRape of TheHero? Oh, check. With a side of really squicky FoeYay.
* Duke Igthorn is the ''[[WesternAnimation/AdventuresOfTheGummiBears Gummi Bears]]''' greatest enemy.
* The Ice King in ''WesternAnimation/AdventureTime,'' although he is eventually replaced by the [[OmnicidalManiac The Lich]].
* Poodle from ''WesternAnimation/AlmostNakedAnimals''.
* [[EvilPoacher The Huntsman]] and later [[SealedEvilInACan the Dark Dragon]] from ''WesternAnimation/AmericanDragonJakeLong''.
* [[spoiler:Barry Dylan]] from ''WesternAnimation/{{Archer}}''.
** Usurped by [[spoiler:Katya]] in "Viscous Coupling".
* Maximus I.Q. from ''WesternAnimation/AtomicBetty''.
* ''WesternAnimation/AvatarTheLastAirbender'' settled this on Fire Lord Ozai, who usurped the throne from his older brother, manipulated his wife into killing his father, psychologically forced his daughter to become a perfectionist and abandoned her when she served her purpose, [[AbusiveParents viciously disfigured and disowned his thirteen-year old son for speaking out of turn]], and is the lead suspect in his wife's mysterious disappearance. A real piece of work, all right, and that's just his ''personal life'' in the ''{{backstory}}''. Professionally, he's an EvilOverlord, who ''gleefully burned half of a continent'' just to '''quell a few uprisings'''.
* ''WesternAnimation/AvengerPenguins'' - Caractacus P. Doom. As if life could hold anything else in store for a chap with a name like that.
* ''WesternAnimation/AvengersEarthsMightiestHeroes'' had [[spoiler: Loki]] as the ultimate Big Bad of its first season, and Baron Strucker, Baron Zemo, the Leader, Kang the Conqueror, and Ultron as Big Bads of smaller arcs within the season.
** In the second season, the Skrulls, lead by Queen Veranke, were the main villains for the first half (the second half, being more episodic, didn't really have one, though it was all leading up to a showdown with [[spoiler: Galactus]]).
* Todd Ianuzzi from ''WesternAnimation/BeavisAndButtHead'', also an example of BigBadFriend.
* Vilgax, from ''WesternAnimation/{{Ben 10}}'', is a textbook example. He's wounded grievously in the pilot, drives the plot of most of season 1 from behind the scenes, and finally shows up in person in the season 1 finale, bigger, meaner, smarter, and tougher than anything Ben's faced before. From there on out, he's usually put somewhere between appearances that keeps him from getting involved... He's also an ImplacableMan and a {{Determinator}}, so he HAS to be kept out of the picture for other plot arcs to happen. Here are the other Big Bads for the following seasons:
** Season 2: Kevin 11
** Season 3: Ghostfreak
** Season 4: The Forever King
** For ''WesternAnimation/Ben10AlienForce'':
*** Season 1: The [=DNAliens=]
*** Season 2: The Highbreed
*** Season 3: Vilgax
** ''WesternAnimation/Ben10UltimateAlien''
*** Season 1: Aggregor [[spoiler:and then Kevin]]
*** Season 2: Diagon [[spoiler:but usurped by Vilgax]]
** ''WesternAnimation/Ben10Omniverse''
*** Arc 1: Khyber [[spoiler:who was working for Malware, the ''real'' Big Bad]]
*** Arc 2: Malware
*** Arc 3: The Incurseans
*** Arc 4: Albedo
* [[TheRival Jimmy Pesto]] and [[ObstructiveBureaucrat Hugo Habercore]] from ''WesternAnimation/BobsBurgers''.
* [[ReptilesAreAbhorrent Gaspar le Gecko]] from ''WesternAnimation/BrandyAndMrWhiskers''.
* Agnes Tapili from ''WesternAnimation/BroTown''.
* ''WesternAnimation/BuzzLightyearOfStarCommand'' has Emperor Zurg.
* Jordan Buttsquat from ''WesternAnimation/CampLakebottom''.
* Rancid Rabbit from ''WesternAnimation/CatDog'', sometimes in a BigBadEnsemble with [[SadistTeacher Sally O'Neil]].
* Skrawl on ''WesternAnimation/ChalkZone''.
* Endive from ''WesternAnimation/{{Chowder}}''.
* XANA from ''WesternAnimation/CodeLyoko''. An artificial intelligence villain [[HeWhoMustNotBeSeen who's never seen]], but whose influence is certainly felt.
* On ''WesternAnimation/CodenameKidsNextDoor'', Father was undeniably the top of the villain hierarchy.
** Though, TheMovie revealed an [[OhCrap even more dangerous foe]]: [[SealedEvilInACan Grandfather]].
** [[CorruptCorporateExecutive Mr. Boss]] plays Big Bad a couple times, too, and if there's a LegionOfDoom to be had, he's usually the leader (though Father rarely participates in these).
* Katz from ''WesternAnimation/CourageTheCowardlyDog''.
** Although in the series GrandFinale's "Remembrance of Courage Past"/"Perfect", this is occupied by the Cruel Vet/the Teacher.
* The Red Guy in ''WesternAnimation/CowAndChicken'' and ''WesternAnimation/IAmWeasel.''
* ''WesternAnimation/DannyPhantom''
** Vlad [=Masters/Plasmius=]. He's introduced in episode seven, but his influence is felt as early as ''the opening scenes''. Until his VillainousBreakdown, only two people could claim to lay an effective hand on him: Pariah Dark and Jack Fenton, the latter aided with anti-ghost technology. Some have compared him to Slade in deviousness.
** Pariah Dark himself, despite only appearing twice, one of those being a cameo during a GondorCallsForAid situation, probably counts as well. He's essentially Ghost Darkseid, and is one of the strongest characters, if not the strongest seen in the series.
** Each of the double-length movie episodes has one. First is Pariah, as mentioned above. Next is [[FutureMeScaresMe Dark Danny]], who is somewhat less powerful but a more personal (and psychotic) threat. Then is the ordinary {{Muggle|s}} [[OvershadowedByAwesome Freakshow]], who spends the movie trying to get his hands on an ArtifactOfDoom that will give him [[RealityWarper reality warping]] powers. The final Big Bad is not a person, but rather the ecto-asteroid. As Vlad is still the series-spanning Big Bad, he was active in all of these storylines as well (except for the third).
* Ms. Angela Li from ''WesternAnimation/{{Daria}}''.
* Syrrus becomes this in ''WesternAnimation/DexHamiltonAlienEntomologist''.
* Mandark from ''WesternAnimation/DextersLaboratory''.
* Swiper in ''WesternAnimation/DoraTheExplorer'' can be seen as this.
* Alvin the Treacherous from ''WesternAnimation/DragonsRidersOfBerk''. Later becomes a BigBadEnsemble of Alvin, [[EgomaniacHunter Dagur]], and the [[OurDragonsAreDifferent Screaming Death]] in ''Defenders of Berk'' until [[spoiler:Dagur (nearly) kills Alvin in "A View to a Skrill, Part 2" by using the Skrill to electrocute him to death]], then it's just Dagur and the Screaming Death.
* The Jew Producer from ''WesternAnimation/DrawnTogether''.
* ''WesternAnimation/DungeonsAndDragons'' cartoon series: The ''[[http://www.youtube.com/watch?v=n1-8bEnqtZ4 Evil Incarnate]]'' summoned by the Box of Balefire, which Venger attempts to welcome, calling it "master", until it accuses him of failure and reduces his (most recent) castle to a lava-filled crater. Then it goes after the main characters.
-->'''Bobby:''' C'mon, Dungeon Master, who is it? Or what is it?\\
'''Dungeon Master:''' His name is not for your ears, Barbarian! He is not life as we know it. He has many identities, on many different worlds! But all know him as... Evil!\\
''(Dungeon Master teleports himself and the children to the other side of the world)''\\
'''Dungeon Master:''' The ruler of many universes! But his goal is to rule the entire cosmos with evil.
** Arguably, Tiamat was the more commonly-encountered form. Even ''Venger'' hauled ass when she showed up.
* ''WesternAnimation/EdEddNEddy'': The Kanker sisters are the closest thing this show ever had to one. By [[WesternAnimation/EdEddNEddysBigPictureShow the movie]], they get usurped by [[spoiler: Eddy's Brother]].
** Kevin plays this role frequently throughout the series as well.
* Thanks to the SortingAlgorithmOfEvil, the Big Bad of ''WesternAnimation/TheFairlyOddparents'' has changed a few times. In the first three seasons, [[EvilTeacher Mr. Crocker]] was Timmy's worst enemy, appearing as the bad guy in every special that had a true villain. "The Big Superhero Wish" was the first special where he was not the main bad guy, and "Channel Chasers" reduced him to a cameo. After that, [[EvilTwin Anti-Cosmo]] of the anti-fairies and [[CorruptCorporateExecutive HP]] of the pixies took over for the next three seasons as a BigBadDuumvirate, especially in season six, where the characters never appear separate. Then The Darkness for the "Wishology" trilogy. With the birth of [[EnfanteTerrible Foop]], he took over for season seven (appearing as the villain in that season's finale). The movies are a good example of this.
** Abra-Catastrophe: Crocker
** Channel Chasers: Vicky
** School's Out! The Musical: HP and the Pixies
** Fairy Idol: Norm the Genie
** Fairly Oddbaby: Anti-Fairies and Pixies
** Wishology: The Darkness and the Destructinator
** There's also the ''[[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy]]/Timmy Power Hour'' crossovers:
*** Part 1: Crocker and a malfunctioning Goddard
*** Part 2: Professor Calamitous and Anti-Cosmo
*** Part 3: The Villain Whose Name Isn't Shirley
* Stewie Griffin from ''WesternAnimation/FamilyGuy'' was the Big Bad in the early seasons, although this role has been occupied by Carter Pewterschmidt in later seasons.
* ''WesternAnimation/{{Futurama}}'' doesn't always call for a Big Bad, but when it does, it's almost always RichardNixon's Head or [[CorruptCorporateExecutive Mom]]. Each of [[TheMovie the movies]] have had one.
** Bender's Big Score: Nudar.
** The Beast With A Billion Backs: Act 1: Dr. Ogden Wernstrom. Act 2: Zapp Brannigan. Act 3: Yivo. Act 4: Bender.
** Bender's Game: Mom/Momon.
** Into The Wild Green Yonder: The Dark One/[[spoiler: The desert muck leech]].
* There are two main villains whose overarching schemes [[VillainsActHeroesReact drive the plot]] of ''WesternAnimation/{{Gargoyles}}'': [[MagnificentBastard Xanatos]] and [[WoobieDestroyerOfWorlds Demona]]. As the show progresses, however, [[spoiler:Xanatos]] gets character development leading to a HeelFaceTurn (kind of), leaving [[spoiler:Demona]] the unchallenged Big Bad by the time of the GrandFinale. In [[CanonDiscontinuity season 3]] [[KnightTemplar Castaway]] and his Quarrymen took on the role, while the (canon) comic continuation has [[spoiler:Thailog]] stepping in to fill the empty shoes of main bad guy.
* Van Kleiss from ''WesternAnimation/GeneratorRex'', though it might end up being a bit more complicated than that seeing as White Knight, nominally the BigGood, [[BlackAndGreyMorality isn't the nicest guy himself]]...
* Turk from ''WesternAnimation/GoodVibes''.
* Gideon Gleeful from season 1 of ''WesternAnimation/GravityFalls''.
* ''WesternAnimation/GreenLanternTheAnimatedSeries'':
** Season 1: Atrocitus, leader of the Red Lanterns
** Season 2: The Anti-Monitor, later [[AIIsACrapshoot Aya]] after she destroys it and takes control of its body
* [[AlphaBitch Trina Riffin]] from ''WesternAnimation/{{Grojband}}'', especially in "Ahead of Our Own Tone".
* Horde Prime is the guy giving orders to the much more famous [[WesternAnimation/HeManAndTheMastersOfTheUniverse1983 Skeletor]] and [[WesternAnimation/SheRaPrincessOfPower Hordak]]. He's also a prime example of why NothingIsScarier, as when he finally came out of [[http://www.frankshemanpage.net/micah00.JPG the shadows]] in the comics, [[http://www.bustatoons.com/blog_images/blog_horde_prime_uk.jpg this]] [[{{Narm}} was the result]].
* The Professor in ''WesternAnimation/HuntikSecretsAndSeekers''.
* Stavros Garkos from ''WesternAnimation/{{Hurricanes}}''.
* The Almighty Tallests in ''WesternAnimation/InvaderZim''.
** Depends more on how you look at it: Are they stupid? Yes. But, all Irkens are very materialistic and wasteful, and they are willing to kill everyone on a planet just to they can use them as silly things like parking garages and package shipping.
** Depending on whose side you're on, Zim, Dib, or Tak can also qualify.
** Looking at it from Dib's POV as the HeroAntagonist, you could say that Zim is the Big Bad trying to take over the world, Tak is the Big Bad's more competent [[TheRival rival]], and the Tallest are the BiggerBad trying to take over the whole universe.
* ''WesternAnimation/JackieChanAdventures'':
** Season 1: Shendu, who is consistently treated as the J-Team's most dangerous individual enemy
** Season 2: The Demon Sorcerers (Shendu's brothers and sisters, with Shendu's spirit doing their legwork)
** Season 3: Daolon Wong, [[HijackedByGanon usurped by Shendu]] in the season finale
** Season 4: Tarakudo
** Season 5: Drago, who eventually forces the heroes to unseal Shendu in a SummonBiggerFish moment.
* [[NamesToRunAwayFromReallyFast Lucius Heinous VII]] on ''WesternAnimation/JimmyTwoShoes''
** Some episodes have Lucius as the Big Bad while others have him as a VillainProtagonist.
* The Big Bad of the Cadmus [[StoryArc Arc]] of ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'' was constantly being teased. At first it seemed Amanda Waller was the mastermind, then Lex Luthor, until it was finally revealed in the next-to-last episode as [[spoiler:Brainiac, who enters into a BigBadDuumvirate with Luthor]].
** This was far from the only example in the Franchise/{{DCAU}}. ''WesternAnimation/BatmanBeyond'' had Derek Powers, a CorruptCorporateExecutive who soon became known as the supervillain Blight, as its Big Bad for the first season.
** ''WesternAnimation/SupermanTheAnimatedSeries'' featured an ongoing arc of Superman's struggle with the GalacticConqueror {{Darkseid}}, and his increasingly daring designs on Earth. (By contrast, Lex Luthor's schemes were almost purely episodic in nature.) Darkseid only first appeared in the second season, however: in the first, Braniac was the overarching Big Bad.
** Even Ra's al Ghul in ''WesternAnimation/BatmanTheAnimatedSeries'' arguably qualified, being introduced in the final moments of one episode, and following up on it later with a cataclysmic two-parter.
** There were several contenders for the title in the final season of JLU. At first it looked like Grodd, until he was deposed by [[spoiler:Lex Luthor]] leading to an apparent BigBadDuumvirate between [[spoiler: Lex and the remnants of Brainiac's consciousness]]. In the end, though, the real threat turned out to be [[spoiler:Darkseid. Again]].
* Dr. Drakken and Shego from ''WesternAnimation/KimPossible'' are the primary antagonists and the ones that get closest to their goals.
** Monkey Fist served as the Big Bad of the Yamanouchi arc, but was treated like a MonsterOfTheWeek in the overall series.
* ''WesternAnimation/TheLegendOfKorra'', set seventy years after ''Airbender'', shifts this role to [[FantasticRacism Amon]], RebelLeader of an [[AntiMagicalFaction anti-bending faction]] known as Equalists in Season 1. However, it ended up being more complicated than that seeing as Tarrlok, who at first appeared to be the nominal BigGood, [[BlackAndGrayMorality wasn't really the nicest guy himself]]. [[spoiler:It turned out that he was another Big Bad all along, as he ultimately betrays everyone by staging a FalseFlagOperation that would lead him to arrest innocent non-benders before turning on the Avatar and her comrades. Eventually, he was [[HijackedByGanon put in his place]] by Amon. Then it turned out the two of them were brothers, and had been raised by a villain Aang fought and de-powered during the timeskip. Basically, bad parents are responsible for nearly everything in this universe.]]
** Book 2 has Korra's uncle Unalaq, who is the leader of the Northern Water Tribe that is at war with the Southern Water Tribe led by Korra's father Tonraq. [[spoiler:However, the real threat is revealed to be [[SealedEvilInACan Vaatu]], the spirit of darkness and the Avatar's ancient enemy, who Unalaq merges with in the season finale to become the Dark Avatar]]. There's also a BigBadEnsemble with [[spoiler:Varrick.]]
* ''WesternAnimation/LegionOfSuperheroes'' had a FiveBadBand led by The Emerald Empress as the most common villain in the first season, in the second season the Big Bad was definately [[GalacticConqueror Imperiex]], even though Imperiex was upstaged by Braniac 1.0.
* [[ReptilesAreAbhorrent Delilah]] from ''WesternAnimation/LittlestPetShop1995''.
* [[AlphaBitch Whittany and Brittany Biskit]] from ''WesternAnimation/LittlestPetShop2012''.
* Marvin the Martian and Yosemite Sam from the ''WesternAnimation/LooneyTunes''.
** Marvin himself is the Big Bad in the 2003 series ''WesternAnimation/DuckDodgers''.
* ''WesternAnimation/{{MASK}}'' has [[TerroristsWithoutACause Miles Mayhem]], the leader of VENOM.
* Mary Gibbons and Anton St. Germain from ''WesternAnimation/TheMightyB''. However in the episode "Grumpy Old Bees", this is occupied by [[TerribleTrio Portia, Gwen and Penny]].
* ''WesternAnimation/MonsterAllergy'' had CorruptCorporateExecutive Magnacat in season 1, EvilOverlord Moog Magister and Hector Sinestro, a [[FallenHero dark Tamer]], in season 2.
* Ms. Censordoll in ''WesternAnimation/MoralOrel''.
** Ms. Censordoll was set-up to be the Big Bad but the show ended before anything could come of it. Instead, Clay Puppington becomes the Big Bad.
* Abraham Kane, the leader of Detroit Deluxe in ''{{WesternAnimation/Motorcity}}''.
* In ''WesternAnimation/MuchaLucha: The Return of El Malefico'', the titular character is the Big Bad.
* [[ThreateningShark Bull Sharkowski]] from ''WesternAnimation/MyGymPartnersAMonkey''.
* Vexus from ''WesternAnimation/MyLifeAsATeenageRobot''.
* [[AscendedExtra Sunset]] [[AlphaBitch Shimmer]] from ''WesternAnimation/MyLittlePonyEquestriaGirls'', who steals the crown and antagonizes Twilight throughout her high school experience.
* ''Franchise/{{Ninjago}}'': Pythor in season 1, Lord Garmadon in season 2 up until [[UltimateEvil The Overlord]] takes the position, The Overlord Virus in season 3.
* Joey, Marky & Dee Dee in ''WesternAnimation/OggyAndTheCockroaches''.
* Copernicus from ''WesternAnimation/PackagesFromPlanetX''.
* Betrayus from ''WesternAnimation/PacManAndTheGhostlyAdventures''.
* Gobsmack and Saphira from ''WesternAnimation/{{Pearlie}}''.
* Mojo Jojo from ''WesternAnimation/ThePowerpuffGirls''.
* The Sorcerer from ''WesternAnimation/RandyCunninghamNinthGradeNinja''.
* ''WesternAnimation/ReBoot'' has Megabyte. He is the main villain in this show and never suffered from VillainDecay. He even strands Bob in the Web for 10 episodes. Even after the Daemon arc, which threatened the entire net, Megabyte's return invokes a lot more fear in the heroes. This fear is well founded, as Megabyte takes over the Principal office in less than 2 episodes since returning.
* Citrocet from ''WesternAnimation/TheRippingFriends''.
* Gart [=DeFault=] from ''WesternAnimation/RobotAndMonster''.
* Dr. Kamikazi from ''WesternAnimation/{{Robotboy}}''.
* [[MadScientist Fritz Huhnmorder]] in ''WesternAnimation/RobotChicken'', since he forces the chicken to watch the crossovers on the television.
* Lord Peel from ''WesternAnimation/RocketMonkeys''. He's an IneffectualSympatheticVillain who became a shell of a man (or rather [[{{Pun}} a peel of a banana]]) after Wally and Gus tried to eat him, leading to him making his life goal to destroy them. On rare occasions will the two actually acknowledge him as a threat.
* Aku on ''WesternAnimation/SamuraiJack''. His destruction is one of Jack's two big goals, the other being getting back home.
* Leslie Noodman from ''WesternAnimation/SanjayAndCraig''.
* ''WesternAnimation/ScoobyDooMysteryIncorporated'': The end of season 1 revealed that [[spoiler: Mayor Jones]] was the one behind the whole plot, and he actively confronted the gang in the finale. However, it could also be argued that he [[BigBadEnsemble shared]] the role with [[KnightOfCerebus Professor]] [[FeatheredFiend Pericles]] who is much more active a villain throughout the season. And in any case, at the end of the season [[spoiler: the Mayor]] is arrested, leaving Pericles to take on the role fully.
** In the second season, Pericles has formed a BigBadDuumvirate with Mr. E / [[spoiler: Ricky Owens]], and clearly holds the more dominant position of the two. Basically, Pericles has secured his place as ''the'' Big Bad of this show.
*** Though in the final episodes, [[spoiler: it turns out Pericles has been serving the [[SealedEvilInACan Nibiru]] [[BiggerBad entity]], which in turn has been manipulating events since long before the series started. And in the GrandFinale, it escapes and [[GrandTheftMe steals Pericles' body]], thus becoming the FinalBoss.]]
* V. V. Argost's schemes drive the plot of ''WesternAnimation/TheSecretSaturdays''.
* Vladmire, Kotona School and Bratty Rich Kid from ''WesternAnimation/ShurikenSchool''.
* [[ClassicVillain Master XOX]] from ''WesternAnimation/{{Sidekick}}''.
* Mr. Burns from ''WesternAnimation/TheSimpsons''.
* Dragon, from ''WesternAnimation/SkunkFu'' Ironically, he is not TheDragon.
* Saddam Hussein from ''WesternAnimation/SouthPark'', especially in the early seasons (although in TheMovie, he is more of a BiggerBad).
** Sheila Broflovski is the co-Big Bad in the same movie, with Satan.
** Cartman himself is this, more specifically in the recent seasons and the trilogy "Coon & Friends".
* While the ''WesternAnimation/TheSpectacularSpiderMan'' had several characters vying for the title of boss of the New York underworld, the title belongs to Tombstone, who serves as the Big Bad for the series until he is deposed by [[spoiler: Green Goblin]].
** In ''WesternAnimation/SpiderManTheAnimatedSeries'', the Kingpin and [=Norman Osborn/Green Goblin=] took turns vying for this title, though much moreso the Kingpin than Osborn.
* Plankton from ''WesternAnimation/SpongebobSquarepants'', but he is now in BigBadEnsemble territory with Mr. Krabs.
* Kyle and Salty Mike from ''WesternAnimation/SquirrelBoy''.
* The Big Bad of both ''WesternAnimation/StarWarsCloneWars'' and ''WesternAnimation/StarWarsTheCloneWars'' is, surprising probably nobody, Palpatine/Darth Sidious.
* General Modula in ''WesternAnimation/SymBionicTitan''.
* Chief and Lok from the ''VideoGame/TakAndThePowerOfJuju'' TV series.
* ''Franchise/TeenageMutantNinjaTurtles'' usually has Shredder as the Big Bad, but in the cartoons he is often [[EvilerThanThou topped by some alien threat]]. In the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003]] version of the cartoon, he usually [[HijackedByGanon comes out on top,]] since he took [[NotSoHarmlessVillain about a hundred levels in badass.]]
** In the 2003 cartoon, he cements his position as the Big Bad even further by making plenty of Xanatos Gambits.
** [[EldritchAbomination The Tengu]] (the demon whose legend inspired the Shredder) for season four and five and [[EvilUncle Darius]] [[CorruptCorporateExecutive Dun]] in season six. The 'original' Shredder made his triumphant return in season seven as a digital program and in the flesh in the [[WesternAnimation/TurtlesForever concluding film.]]
** The 2012 cartoon currently features a BigBadEnsemble between the Shredder and The Kraang.
* ''WesternAnimation/TeenTitans'' followed a Big Bad per season formula:
** Seasons 1 and 2: [[ManipulativeBastard Slade]]
** Season 3: [[EvilMentor Brother Blood]]
** Season 4: [[GodOfEvil Trigon]]
** Season 5: [[BrainInAJar The Brain]].
* Creator/{{Disney}}'s Zeke, the Big Bad Wolf from ''Three Little Pigs'' (1933) and its sequels, was originally the Big Bad of his forest world -- as befits his name.
* ''WesternAnimation/ThunderCats''
** In the original series and ''WesternAnimation/ThunderCats2011'', there's SorcerousOverlord {{Mummy}}[=/=]{{Lich}} Mumm-Ra, foe of the title Cats as they foil his attempts to TakeOverTheWorld.
** There were, however, four {{Bigger Bad}}s behind Mumm-Ra, who are never confronted directly and only appear in statue form. Mumm-Ra isn't even their strongest follower; that honor goes to Pyron, who [[DiabolusExNihilo appeared out of nowhere]] to be the FinalBoss of the original series.
* Joy Peters from ''WesternAnimation/TomGoesToTheMayor''.
* In each season of ''WesternAnimation/TotalDrama'', there's a contestant that's causing the most trouble.
** ''Island'': [[RichBitch Heather]]
** ''Action'': [[{{Bishonen}} Justin]] [[DiscOneFinalBoss then]] [[AntiVillain Courtney]].
** ''World Tour'': [[DashingHispanic Alejandro]], with [[BlondesAreEvil Blaineley]] as the antagonist for the Aftermath Specials.
** ''Revenge of the Island'': [[FarmBoy Scott]], then [[JerkJock Lightning]] in the finale.
** ''All Stars'': [[TheMentallyDisturbed Mike]] as [[SuperPoweredEvilSide Mal]], with [[TheChewToy Ezekiel]] as the antagonist for "Zeke and Ye Shall Find", the 100th episode of ''Total Drama''.
* Quint in ''WesternAnimation/TimonAndPumbaa''.
* Megatron in almost every incarnation of ''Franchise/{{Transformers}}'', only to usually force an EnemyMine when Unicron appears.
** ''Generation 1'': Led the Decepticons on Cybertron and constantly tried all sorts of evil schemes to steal energy from Earth. Since these plans tended to fail, the writers eventually resorted to an EnemyMine plot every other episode to avoid Villain Decay.
** In ''WesternAnimation/BeastWars'', he was the Big Bad twice. Firstly he's the standard ruler of the Predacons, fighting against the Maximals. During TheReveal, it is shown that the G1 Megatron had orchestrated the plan, ordering the Beast Megatron to [[TimeyWimeyBall go back in time]] and kill the G1 Autobots while they were in stasis. Only for that plan to be ignored. ''WesternAnimation/BeastWars'' Megatron only followed this plan as a last ditch effort, in only one plot, which failed. (Thankfully so, or they all would have been killed by Unicron at some point). Other plots include successfully killing both Optimuses (Optimi?), inventing new classes of Transformers (Transmetal 2, Vehicons) and introducing [[LargeHam ham]] to prehistoric Earth.
** ''WesternAnimation/BeastMachines'': succeeds in conquering Cybertron and ruling over a planet of mindless, sparkless drones. All this happens ''before the series begins''. During the series, he absorbs every spark on the planet and comes within a millimetre of [[AGodAmI godhood]]. Yes, godhood.
** ''[[Anime/TransformersArmada Armada]]'': Leads the Decepticons and gets his servos on the three most powerful minicons in the universe and would probably have destroyed the Autobots if Unicron hadn't forced them into an [[EnemyMine alliance]].
** ''[[Anime/TransformersEnergon Energon]]'': Rallies the Decepticons into once again fighting against the Autobots, then hijacks Alpha Q's plan to restore his home planet and instead manages to successfully revive and, for a time, control Unicron. Oh, and he reformats Scorponok's and Demolishor's sparks to make them less moral and more loyal to himself.
** ''[[Anime/TransformersCybertron Cybertron]]'': Goes after the Omega Lock and the four Cyber Planet Keys to steal the power of Primus and become a god. He intends to use the Unicron Singularity to destroy the universe and then recreate it as he pleases. Starscream successfully betrays him and nearly usurps this spot, but Galvatron beats him [[Awesome/{{Transformers}} in an epic showdown]]. [[spoiler: Luckily for the universe, he is beaten on the verge of success and is slain by Optimus Prime in [[Awesome/{{Transformers}} another epic battle]].]]
** ''WesternAnimation/TransformersAnimated'': His body was destroyed in the pilot, leaving him a head in a scientist's lab. Hooked into the lab's computers, and with the right words to Professor Sumdac, he spends the first season working on getting a new body and taking shots at the Autobots through intermediaries. When he gains a new body and comes bursting out of Sumdac Tower in the first season finale, the 'bots know ''exactly'' how screwed they are. Circumstances still force him to spend most of his time plotting, but it's still a step up from "Decepticons, RETREAT!"
** ''WesternAnimation/TransformersPrime'': Arrives on Earth via space bridge during the FiveEpisodePilot, armed with "Dark Energon", which has the power to revive Cybertronian corpses as mindless berserkers. [[spoiler: The mini-series ends with him and an undead army disappearing in a space bridge explosion. Starscream promptly becomes the DragonAscendant and takes over as Big Bad for the next several episodes, but Megatron is ultimately revived and retakes the top spot. In the last few episodes of Season 1, though, he's overshadowed by Unicron as the premier threat, only to retake the position in Season 2. ]]. This series so far as a pattern of alternating between Megatron and someone else for chunks of episodes, going Megatron-> Starscream-> Megatron-> [[spoiler: Unicron]]-> Megatron.
*** [[spoiler:Unicron will be the Big Bad of "Predacons Rising".]]
** The Japanese series have added some other Big Bads, such as Scorponok, Devil Z, Overlord, Deathsaurus, Violen Jiger, and Dark Nova.
** The Japanese sequels to ''WesternAnimation/BeastWars'' also had their own. ''Beast Wars II'' had brothers Galvatron and Megastorm, and ''Beast Wars Neo'' had Magmatron.
** The comics also added a few of their own, including Shockwave, Thunderwing, Ratbat, Bludgeon, Soundwave, Straxus, Scrash, Trannis, Clench, and Jhiaxus. The finale of the ''Generation II'' comic revealed that ALL of the ''G1''-era Big Bads were unknowingly reporting to [[spoiler:Liege Maximo, the very first Decepticon.]] Unfortunately, the comic was canceled immediately after this revelation, so that storyline never went anywhere.
* Simon the gremlin in ''WesternAnimation/{{Trollz}}''.
* Verminious Snaptrap, The Chameleon, and Bird Brain from ''WesternAnimation/TUFFPuppy'' form either a BigBadEnsemble or in some episodes a BigBadDuumvirate.
* ''WesternAnimation/TheVentureBrothers'' has a BigBadEnsemble between The Monarch and Phantom Limb. Between the two, Phantom Limb is the better candidate as The Monarch is seen as BigBadWannabe and VillainProtagonist, whereas Phantom Limb was a straight out KnightOfCerebus and tried to pull a [[TheStarscream Starscream]] on the Guild of Calamitous Intent.
* ''WesternAnimation/{{Wakfu}}'' has [[JerkassWoobie Nox]] for the first season, and [[GodOfEvil Rushu]] for the second.
** Actually Rushu ended up just being used by the real Big Bad: [[spoiler:[[PsychopathicManchild Qilby]]]]
* Lord Hater from ''WesternAnimation/WanderOverYonder''.
* ''WesternAnimation/WinxClub'':
** Season 1: The Trix
** Season 2: Lord Darkar
** Season 3: Valtor

** Season 5: Tritannus
* ''WesternAnimation/{{WITCH}}'' had EvilOverlord Phobos in season 1, who was succeeded by Nerissa, a {{Chessmaster}} and [[FallenHero former Guardian]], in season 2. Nerissa was manipulating from behind the scenes even during season 1. Pretty impressive, considering she was [[SealedEvilInACan trapped in a coffin for quite a while.]]
* ''WesternAnimation/XMen'' has Apocalypse in a more series-wide capacity, since Magneto's HeelFaceRevolvingDoor was played up. Mister Sinister clearly holds this status in Season 2, though.
** In ''WesternAnimation/XMenEvolution'', Magneto is the Big Bad for the first two seasons, and Apocalypse takes the role in the last two.
** And in ''WesternAnimation/WolverineAndTheXMen'', [[AIIsACrapshoot Mastermold]] is the Big Bad of the BadFuture Xavier is stuck in, while [[WellIntentionedExtremist Magneto]] and Senator Robert Kelly largely takes the role among several long-term villains [[spoiler: Though the Inner Circle also has a pretty good claim on driving a lot of the plot]]. The SequelHook set up [[spoiler: Apocalypse]] as the Big Bad for an aborted second season.
* Rondo Jr. from ''WesternAnimation/YakkityYak''.
* [[OmniscientCouncilOfVagueness The Light]], which consists of VandalSavage, [[Really700YearsOld Ra's al Ghul]], SelfDemonstrating/LexLuthor, [[GodSaveUsFromTheQueen Queen Bee]], [[ComicBook/{{Aquaman}} Ocean Master]], [[BrainInAJar The Brain]], and [[HumanoidAbomination Klarion the Witch Boy]] in season 1 of ''WesternAnimation/YoungJustice''. In season 2, the Light replaces Ocean Master with Black Manta.
** In Season 2, the Light shares the role of Big Bad with their mysterious "partner", later revealed to be [[AlienInvasion the Reach]], who are led by [[ManipulativeBastard the Ambassador]], [[MadScientist the Scientist]], and [[SmugSuper Black Beetle]]. Of course, both groups are also using and plotting against the other [[spoiler: and at the end of the season, Black Beetle takes full command of the Reach and sets in motion the doomsday threat the heroes must deal with in the GrandFinale]].
** However, the very last scene of the final episode revealed that [[spoiler: the Light (or at least Vandal Savage) had been working with Darkseid the entire time, implying that the Lord of Apokolips would have stepped up to fill this role had the series continued]].
