"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.
* ''Roleplay/AGameOfGods'' originally had Omega as the Big Bad, who was behind all the disappearing Champions and was possessing a doomsday device. However, after he kicked the bucket, Lambda came in and some FridgeHorror came up, resulting in them going back for Echidna and confronting the true Big Bad, Digamma.
* Later seasons of ''Machinima/ArbyNTheChief'' have Big Bads.
** Scott in Endgame.
** Trent Donnovich in Season 5. The CEO of video game company Bad Games, he's to be wed to Arbiter's friend Claire. It's eventually revealed though that [[spoiler:Trent is cheating on her, prompting Arbiter and Chief to crash the wedding.]]
** Clyde, leader of Chaos Theosis, in Season 6. His gang of hackers seeks to get rid of TOSERS via fragbanning all of the organization's members and shut down the Online Multiplayer Network. It's revealed later on though that the clan was actually being employed by [[spoiler:[[HijackedByGanon Trent Donnovich]].]]
** Season 7 has [[spoiler:Eugene and his trolling clan. At first, they seem like a band of harmless, annoying trolls whom the duo befriend. This changes once the resident SmartGuy, Colin, acquires an upgraded version of Fragban, and the clan goes on a fragbanning spree throughout the OMN.]]
* ''WebVideo/AtopTheFourthWall'' is noted for having a central antagonist for each storyline:
** "The Dr. Insano Saga": [[ExactlyWhatItSaysOnTheTin Dr.]] [[MadScientist Insano]];
** "His Heart is Steel": [[EvilTwin Mecha]][[KnightOfCerebus kara]];
** "The Other Insano": [[IneffectualSympatheticVillain Dr. Linksano]];
** "Linkara Lost": [[MultiversalConqueror Lord Vyce]];
** "A Story of Magic": Technically, Lord Vyce is still the [[GreaterScopeVillain main antagonist]], but [[spoiler: [[BigBadWannabe Whatley]], [[BackFromTheDead Mechakara]] and [[LiteralSplitPersonality the Magic Gun's dark side]]]] all play the role of TheHeavy / BigBadEnsemble;
** "All That He Sees, He Conquers": [[FinalBoss Lord Vyce]];
** "A Piece of the World is Missing": [[EldritchAbomination The Entity]] / [[spoiler: [[VideoGame/PokemonRedAndBlue Missingno.]]]];
** "His Blue Soul": Initially, we're led to believe that it's Mechakara, but it's revealed that the true villain of the arc is [[spoiler: Lord Vyce]];
** "Guns and Sorcery": [[AntiVillain Jaeris, the Gunslinger]], with [[EvilCounterpart Holokara]] serving as TheHeavy [[DiscOneFinalBoss for the first half of the story]] and [[spoiler: [[TheBusCameBack Dr.]] [[HijackedByGanon In]][[TookALevelInBadass sano]]]] [[FinalBoss for the climax]];
** "Ghost in the Machine": Just like in "His Blue Soul", we're led to believe that it's a different villain than it actually is; in this case, we're led to think it's The King of Worms, but once again, it's [[spoiler: Lord Vyce]];
** "The Machinations of Worms": [[HumanoidAbomination The King]] [[TheCracker of Worms]].
** "The Movie": Mechakara, revived after the events of ''WebVideo/ToBoldlyFlee''.
** "The Sleepwalker": [[spoiler: An EvilVsEvil BigBadEnsemble of the Entity fragment, which possessed Linkara after the main Entity's death, and Lord Vyce, who winds up being the FinalBoss]].
* ''WebAnimation/BunnyKill'' had a different Big Bad for each installment. (each takes place in an {{alternate continuity}}, you see.)
** Smoke in ''Bunny Kill 1''.
** Dust in ''Bunny Kill 2''.
** Professor Sludge in ''Bunny Kill 3''.
** Flint in ''Bunny Kill 4''.
** Smoke again in ''Bunny Kill 5''.
* [[spoiler:Oswald Sherzikien]] in ''WebVideo/TheCartoonMan'' series, who remains HeWhoMustNotBeSeen for the duration of the first two movies.
* The big bad of ''Literature/ChaosFighters main series'' is the demon lord while ''Literature/ChaosFighters II'' is [[spoiler:Thanic Snader]].
* ''Literature/TheCityOfNever'' has [[spoiler:Draynak, the deity who is trying to destroy all of the Teraverse]].
* [[spoiler:Vecna]] is this in ''WebVideo/CriticalRole'', his return [[spoiler:and later ascension]] being the motivation behind the Briarwood's plans.
* The Medic who leads oWn in ''Machinima/CultOfPersonality''. The series begins with [[StartOfDarkness him being fired from the BLU team and forging his own organization.]] He's personally leading a campaign to destroy RED and BLU.
* ''Literature/DisAcedia'' has Lazarus, a malevolent and sadistic god of magic abducting people to the titular maze.
* The Big Bad of the ''WebVideo/DontHugMeImScared'' series is [[spoiler:Roy, who is implied to have created the DHMIS universe to punish Yellow Guy via a console used to summon and control the teachers.]] Each installment has its own Big Bad, and they are collectively known as "the Teachers":
** The original Don't Hug Me, I'm Scared/"Creativity": Sketchbook... [[AmbiguouslyEvil kinda; it's unclear if they were actually evil or if things just spiraled out of their control.]]
** 2/"Time": Tony the Talking Clock. While at first appearing to be affable and somewhat goofy, he shows himself to be evil when he [[spoiler:speeds up time to rot the puppets alive]] for questioning time.
** The "HELP" videos: The Money Man (not a teacher).
** 3/"Love": Shrignold the Butterfly, head of a Love Cult who worship a giant stone face named [[TomTheDarkLord Malcolm]].
** 4/"Computers": Colin, a talking computer who traps the puppet trio in {{Cyberspace}}.
** 5/"Health": The Healthy Band, who tell the puppets contradicting things on what and what isn't healthy, with the steak being the most prominent. They're laughable as ever, but horrifically, [[spoiler:they go as far as to ''kill'' Duck Guy by having his friend eat him.]]
** 6/"Dreams": The Lamp is set up as a decoy Big Bad, while the Big Bad of the whole series is revealed: [[spoiler:Roy, the father of one of the protagonists.]]
* Bad Horse from "WebVideo/DoctorHorriblesSingAlongBlog."
** Or Dr. Horrible himself, since he's a VillainProtagonist. Captain Hammer could also count.
* [[WesternAnimation/MyLittlePonyFriendshipIsMagic Celestia]] takes this role in ''Roleplay/EquestriaChronicles''. [[GreaterScopeVillain Possibly.]]
* The Executive is shaping up to be this in ''WebOriginal/FalloutIsDragons''.
* ''Literature/FineStructure'' has Oul, an OmnicidalManiac and all-around EldritchAbomination.
* In Creator/FrancisEDec's rants, the Worldwide Mad Deadly Communist Gangster Computer God, whose name tells you all you need to know about it.
* In Roleplay/TheGamersAlliance, several villains have had this role in different story arcs:
** War of the Andain: [[WellIntentionedExtremist Kagetsu Aurelac de Maar Sul (Kagetsu I)]], the Dark Andain.
** Chaos War: [[GodOfEvil Mardük]], the God of Chaos.
** Cardian War: [[TheChessmaster Jemuel]], usurper of the Cardian throne.
** Sydney Losstarot War: Initially [[EvilOverlord Sydney Losstarot]] the warlord, then his [[DragonAscendant demonic lieutenant]] [[OmnicidalManiac Yurius]].
** Ofuchi Usurpation: [[EvilSorcerer Taro Ofuchi]], the shaman.
** Manster Rebellion: [[SmugSnake Kheldar]] and [[HijackedByGanon Yurius]].
** Arawn Losstarot War: [[AntiVillain Kagetsu I]] the Dark Andain and Arawn Losstarot the warlock.
** The Great War: At first it looks like [[FourStarBadass Shogun Masamori Hyuga]] is the Big Bad, then the dark cleric [[SorcerousOverlord Distreyd Thanadar XII]] becomes one, and finally the revived god [[SealedEvilInACan Mardük]] takes the mantle.
* [[TheChessmaster The Emperor]], leader of [[NebulousEvilOrganization TAROT]], has his fingers in nearly every criminal enterprise on Earth in the ''Roleplay/GlobalGuardiansPBEMUniverse''. He's also got his fingers in nearly every major legitimate business enterprise on Earth as well. But then, what do you expect of a villain who is secretly an immortal Creator/NiccoloMachiavelli?
* The mysterious phantom thief Deus serves as this for GrandmasterOfTheft.
* In ''Literature/GreekNinja'', it turns out that the no-match-for-any-human-being force that was so strong it could destroy the whole world, was in fact nothing more than a bitter human being himself, [[spoiler: who was purposefully reincarnated simply to get revenge and restore the reign of the Olympians.]]
* Michelle Clore from ''WebVideo/{{KateModern}}'' is responsible, either directly or indirectly, for nearly everything that goes wrong over the course of the series.
* Dr. Josh Sherman serves as the Big Bad in the pilot story of ''Literature/LightningDust''.
* ''WebAnimation/MadnessCombat'' had the Sheriff as its first Big Bad, who got killed relatively quickly, followed by Jebus and eventually the Clown. Then the Auditor showed up and things ''really'' hit the fan.
* ''WebVideo/MarbleHornets'': Alex Kralie.
* In ''WebAnimation/MarioBrothers'', King Koopa is this with his army of troops. He personally kills Luigi and plans to kill the Princess and Mario.
* ''WebVideo/MindMyGap'' has the Devil himself, Virgil S. Horn, who narrates the entire ordeal from behind the scenes before finally making his reveal at around the half way point.
* In the WebAnimation/MyLittlePonyMeets, in The Joker Meets My Little Pony, Zod and Chrysalis in Superman Meets My Little Pony, Slenderman in ??? Meets My Little Pony.
* Deathstroke is the main villain for Season 1 of ''WebVideo/NightwingTheSeries''.
* ''Literature/ThePiratesCoveredInFur'': Captain Lyle Krinkor, the wolf pirate who's trying to destroy Diamond City and doesn't care how many innocents are caught in the crossfire.
* The Mysterious Somebody, Bracket Fungus and League of Mary-Sue Factories take this role for the ''WebOriginal/ProtectorsOfThePlotContinuum''. Despite being long dead, the Mysterious Somebody could be said to be the most influential Big Bad, as his actions more or less shaped the PPC's identity in-story; the League is a series of offshoots from his original Mary-Sue Factory, and the organisation of the PPC itself is a reaction to his actions as its head.
* Originally it was implied that Ozzie Arcane was the Big Bad of ''WebVideo/TheQuestForGeekdom'', but it was eventually revealed to be [[spoiler: Eric Rosethorn]].
* Plenty of Big Bads in ''Literature/TheQuestportChronicles'': [[EvilSorcerer The Master of Darkness]], [[EldritchAbomination The Prince of Shadows and Illusions]], and [[spoiler:[[NoNameGiven the mage]]]].
* Machinima/RedVsBlue has a couple, actually.
** Machinima/RedVsBlueTheBloodGulchChronicles has O'Malley, though he's LaughablyEvil and comes across as a complete parody of a Big Bad.
** Machinima/RedVsBlueTheRecollection has the Meta, though he alternatively shares the spotlight with [[BigBadEnsemble C.T.]] in Recreation and [[spoiler:[[BigBadDuumvirate Washington]]]] in Revelation.
** Machinima/RedVsBlueTheProjectFreelancerSaga is setting up [[spoiler:the Director]] as the villain, particularly for the flashback episodes. Season 10 also reveals [[spoiler:Sigma as the true Big Bad of ''Reconstruction'' and the GreaterScopeVillain of ''Recreation'' and ''Revelation'']].
** Machinima/RedVsBlueTheChorusTrilogy has [[spoiler:Control, Locus' mysterious boss. It's eventually revealed that Control is part of a third party and behind the CivilWar on Chorus as a whole, and that Felix is also working for him. The revelation that he's the Chairman of the Oversight Sub-Committee and that he funded the Insurrection makes him the GreaterScopeVillain for possibly the entire series]].
** Season 15 looks to have [[spoiler:Temple, leader of the rogue Simulation Troopers who are carrying out attacks against the UNSC and the one behind the disappearances of the Freelancers.]]
* ''A Scooby Story'' has ''Barney,'' of all characters, as the villain.
* ''Literature/SmirvlaksStone'' has [[spoiler:Gnekvizz Corveel, who secretly manipulated Stilyk and Nick into delivering the eponymous stone to his group of villains]].
* The "dark, unidentifiable figure" from [[http://strangerstories.yolasite.com/ The Stranger]]
* Danya commands the terrorist organization in charge of ''Roleplay/{{Survival of the Fittest}}'', and is therefore primarily responsible for the students being abducted and forced to kill one another, even though as of yet it is unknown if he has ever directly killed anyone. This makes his status as Big Bad inarguable. [[spoiler:At least until he's killed by [[TheDogBitesBack Dorian Pello]].]]
** Each ''Survival of the Fittest'' Endgame tends to have one major villain from the students too. V1 had [[spoiler: Cody Jenson, the killer of [[TheHero Adam Dodd's]] girlfriend and best friend]], V2 had [[spoiler: Mariavel Varella, the biggest killer on the island, who further cemented her status when she killed [[TheHero Bryan Calvert's]] girlfriend,]] and V3 had [[spoiler: J.R. Rizzolo, who [[TheBadGuyWins actually ended up winning]]]].
%%* The Shadows from ''Literature/{{The Tale of Gaven Morren}}''.
* Taco Man, in "Taco Man: The Game Master," has certain villians. In "Taco Man Plays A Video Game," however, when he got tired of playing VideoGame/{{Bubsy}}, Taco Man had a dream of a evil Bubsy forcing Taco Man to play Bubsy 3D, and then, Taco Man realized it wasn't a dream, because the Bubsy 3D title screen was on Taco Man's TV, and the evil Bubsy forced Taco Man to play Bubsy 3D, and then, after Taco Man was treated to a death animation in Bubsy 3D, the evil Bubsy said that there was Bubsy II and Bubsy for the Jaugar, and the evil Bubsy disappears.
* Doctor Insano certainly fits this for the Website/ThatGuyWithTheGlasses team, being the ArchEnemy of [[WebVideo/AtopTheFourthWall Linkara]] and [[WebVideo/TheSpoonyExperiment The Spoony One]], as well as an enemy of many others such as [[WebVideo/TheAngryJoeShow Angry Joe]], WebVideo/TheNostalgiaCritic and WebVideo/PawDugan.
** For the anniversaries, WebVideo/{{Kickassia}} has [[VillainProtagonist NC himself]], WebVideo/SuburbanKnights has [[KnightOfCerebus Malachite]], and WebVideo/ToBoldlyFlee is arguable, with either [[TheChessmaster The Executor]] or [[spoiler:[[UltimateEvil Ma]]-[[WesternAnimation/CaptainPlanetAndThePlaneteers Ti.]]]]
* Garret Meyer in this ''WebVideo/DoorMonster'''s [[https://www.youtube.com/watch?v=Uam0KMyZh2E&index=3&list=PL0u5ZHidq4X4QhFAX9FzSiYJLRen74sLF The Guards Themselves]], imprisoning most of The Anarchists and trying to take control of the entire city.
* ''WebVideo/ThereWillBeBrawl'' has [[spoiler:the Butchers, Lucas and Ness, which are the Dragons to Kirby, the real Big Bad. Ganondorf is the BigBadWannabe, right up until he's executed.]] Add in the {{Cosmic Horror}}s and End of Days cult and we practically have a BigBadEnsemble.
* ''Literature/ToWelcomeOblivion'' has [[spoiler:Noah T. Trepaly, who is the true mastermind of the entire plot. He's also secretly [[Franchise/CthulhuMythos Nyarlathotep]].]]
* This role is occupied by whoever currently controls Team Noir in ''Roleplay/{{Toro League}}''. This was originally Shadow X, though later the role was taken over by the since-defeated-but-not-yet-replaced Reaper Z.
* ''Literature/{{TOT}}'' has Maximus Slade, the malevolent werewolf who constantly torments the main characters and slaughters dozens of innocents on Halloween in a twisted form of entertainment.
* LetsPlay/TwitchPlaysPokemon. Yes, the entire "canon" is made up of AscendedFanon, but surprisingly each instalment so far has had one character whom the Mob basically all agrees to blame for anything bad (Pokémon getting [[KilledOffForReal released]], countdown [[TimedMission timers]], etc).
** LetsPlay/TwitchPlaysPokemonRed had the Dome Fossil, a SatanicArchetype God of [[LawfulEvil Order]] and [[DemocracyIsBad Democracy]] said to be served by Bill (and therefore, by extension, the PC).
** LetsPlay/TwitchPlaysPokemonCrystal had Lord Helix, [[RogueProtagonist Big Good of the previous game]], God of [[ChaoticEvil Chaos]] and [[AnarchyIsChaos Anarchy]].
** LetsPlay/TwitchPlaysPokemonEmerald had Bill [[DragonAscendant ascend]] into this role himself as a NeutralEvil mastermind.
* ''Podcast/WelcomeToNightVale'': Strex Corp in Year Two, with the Smiling God as the BiggerBad.
* There are lots of Big Bads in the ''Literature/WhateleyUniverse''
** The unseen supervillain Nimbus seems to be behind everything. The superweapons at Halloween, the deviser drug used on Merry and maybe also G-Force, and so on. Even some of the Christmas holiday adventures had Nimbus lurking somewhere behind the scenes. We still don't know what he's up to.
** That said, [[spoiler: "Señor X"]] seems to be responsible for everything that Nimbus ''isn't''. Among other things, he's indirectly responsible for [[spoiler: everything Hecate did, and by connection, half the bad stuff the Alphas were up to early on]]. More importantly though, a recent story revealed that [[spoiler: There was a very powerful and very subtle spell active on campus designed to increase tension and conflict]], and he's implied to be the one responsible -- making him [[spoiler: indirectly responsible for the actions of more or less every on-campus bad-guy to date]]. Oh and it's practically been confirmed by this point that [[spoiler: he's masquerading as a student]].
** In the recent story "Razzle Dazzle", Thomas Townsend, alias Mephisto the Mentalist, alias Cerebrex the Super-Brain, claims to have been scheming against many different heros for over eighty years. Under the alias Dominus, he's the current boss of the Syndicate. We don't know for such how much of this is true, since Thomas Townsend admits that he's an UnreliableNarrator.
** Considering how little we know about these Whateley Big Bads, it's possible that two or more of them are the same person.
* ''Literature/{{Worm}}'' at first appears to have a BigBadEnsemble, between the multitudes of supervillains, the three [[OmnicidalManiac Endbringers]], the [[PsychoForHire Slaughterhouse 9]], and [[NebulousEvilOrganization Cauldron,]] but the best contender for the role is the Simurgh, the third of the Endbringers, a malevolent, massively powerful telepath and precognitive with a fondness for DisasterDominoes and [[ManchurianAgent brainwashed pawns]], who is essentially responsible for the world being in the state that it is by sabotaging any attempts to improve the world almost before they start, and who may be TheManBehindTheMan for any of the above.
** [[spoiler: However, the real Big Bad turns out to be [[PhysicalGod Scion]], who spends most of the story looking like the BigGood.]]
* Serias fills this role in ''WebVideo/WormtoothNation''.
* ''WebAnimation/{{Xionic Madness}}'' has [[EldritchAbomination XV]] in episodes 1, 1.5 and 2, [[NonActionBigBad The Overseer]] in episode 3, and [[spoiler:Kary-08]] in episode 4.
* In ''WebVideo/YandereHighSchool,'' Yuki. She killed the first main teacher, Gareth's wife, leading to [[DrivenToSuicide his haunting of the school,]] because Taurtis jokingly had an interest in her. She also framed Chan-Yandere for running over Salex, Taurtis' girlfriend, and led her father's [[YakuZa yakuza]] against Sam and Taurtis in the first season's finale. The showdown resulted in Sam, Taurtis, Grian, and Dom having to go into the witness protection program and move.
* Israphel is this in ''[[Machinima/YogscastMinecraftSeries Shadow of]] [[Machinima/ShadowOfIsraphel Israphel]]'', having antagonized Knight_Peculier all his life, and is currently trying to destroy the world, and we ''still'' don't know who he actually is. [[spoiler:Then it turns out he may have actually been working for [[GreaterScopeVillain the Sand God/Jade Sentinel]]]], but [[LeftHanging we may never know]].
