[[caption-width-right:350:"Gentlemen...To evil!"]]

->''"[[MeanwhileBackAtThe Meanwhile, at the]] LegionOfDoom..."''

Plot of an episode or StoryArc, wherein one or more villainous characters -- usually made up of some combination of past one-shots, members of the RoguesGallery, and/or a few possible newcomers -- join forces to destroy their common enemies, the protagonists.

Usually, they will initially overpower the heroes, but their own evil selfishness and inability to trust each other undermines their unified front, and the heroes strike at this weakness. Or one dominant personality double-crosses the others. Either way, the team dissolves at the end.

Often saved for a season or series finale. {{Crossover}}s do this a lot, using one villain from each series.

[[TropeNamers Named after]] the nemesis organization to the ''WesternAnimation/{{Superfriends}}'', who came together during the third season and actually managed to stay together, mostly due to relentless use of a DiabolusExMachina ResetButton to escape in the last scene, usually because their Hall of Doom can ''fly'' or ''burrow'' anywhere, and because their opponents, the Superfriends, frequently ''[[ForgotAboutHisPowers forget they have super powers]]''.

Likely to be a BigBadDuumvirate as well. EvilIsOneBigHappyFamily is usually involved. For one-shot team ups that are usually on a smaller scale, see VillainTeamUp.

Contrast SuperTeam, their good equivalent.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* In ''Manga/RanmaOneHalf'' during the Moxibustion StoryArc, Ranma was weakened and Happosai (the guy who weakened him) told every enemy that Ranma had, and they all ganged up on him to give him a beatdown. [[TheOnlyOneAllowedToDefeatYou All but one ...]]
* Parodied with usual relish in ''WebVideo/YuGiOhTheAbridgedSeries'' with the episode "Marik's Evil Council Of Doom".
%%* There was a MonsterOfTheWeek in the first season of ''Anime/SailorMoon'' that did this, with predictable results.
* Before ''Series/KamenRiderDecade'''s Great Shocker below, there was the Badan Empire in ''Manga/KamenRiderSpirits'', which revived every single MonsterOfTheWeek and BigBad from the ''Franchise/KamenRider'' franchise up to ''Series/KamenRiderSuper1'' midway through the plot.
* Even ''Manga/{{Naruto}}'' manages to pull this off, by way of [[spoiler:Kabuto's Edo Tensei, resurrecting ''many'' foes that either Naruto faced himself, or are enemies of the collected Shinobi villages as a whole. Worse, some of the line-up included some ''friends and family'' to the heroes!]]
** Not exactly, since [[spoiler: they are all victims of MindControl, and though some have more problem with whats happening than others, most would gladly rip Kabuto's head off for what he's done to them.]] However, its played straight in-universe with [[spoiler: Kabuto again, allying with Tobi who has allied with Sasuke, and revealed himself as the leader of Akatsuki (though most of them are now dead)]]. Akatsuki also qualifies, since it is an organization hose membership includes the most dangerous criminals in the ninja world, though from an audience perspective most of them are new characters.
* The first part of the Super 17 saga of ''Anime/DragonballGT'', where the gates of HFIL break open, releasing an army of villains from both the original series and Z.
[[/folder]]

[[folder:Comic Books]]
* Alex Ross, a huge ''WesternAnimation/{{Superfriends}}'' fan, did a limited series called ''Comicbook/{{Justice}}'', which was his DarkerAndEdgier version of the series. Check out [[http://upload.wikimedia.org/wikipedia/en/6/64/Legion_Of_Doom_(Justice).jpg his vision of the Legion]].
* Naturally, absurdly common in comic books. There was even a short-lived Creator/{{Marvel|Comics}} series, ''Super-Villain Team-Up''. However it was really a minor example as it mostly came down to SelfDemonstrating/DoctorDoom and [[Comicbook/SubMariner Namor]], though the last couple of issues were about RedSkull and the Hate Monger.
* ''Batman's Gangland Guardians'' featured an assembly of {{Franchise/Batman}}'s foes. Fearing that a new mysterious supervillain might actually succeed in killing Batman, they act to secretly protect him. The rationale being that [[TheOnlyOneAllowedToDefeatYou only they, who have put in the time an effort, deserve to be in the running for Batman's final defeat]].
* Another one from DC was the shortlived ''Secret Society of Super-Villains'', in which a collection of old school villains form a sort of anti-Franchise/JusticeLeagueOfAmerica and fight the newly-arrived {{Darkseid}} and company. In one memorable scene, Gorilla Grodd has a punchout with a giant club wielding member of the ''New Gods'', and defeats him with the aid of a classic wrestling ploy, the {{heel}}ish [[ISurrenderSuckers mock surrender]]. The Society even had their own series.
** Later expanded during and after ''ComicBook/IdentityCrisis''. Witnessing the JLA's much more proactive stance after the murder of Sue Dibny, most of the supervillains band together and form an international organization. This version lasted up until ''Comicbook/{{Flashpoint}}'' and the ''Comicbook/{{New 52}}''.
* The whole premise of the miniseries ''Comicbook/{{Wanted}}'' is that the villains ''don't'' fall to bickering and instead destroy all the heroes and take over the world. (It's only ''after'' the heroes are gone and they are the unequivocal masters of all the world that the infighting starts, mirroring some RealLife political coups by [[StrangeBedfellows politically expedient alliances]].)
* Another Franchise/{{Batman}} example. In an issue of a [[TheGoldenAgeOfComicBooks Golden Age]] Batman comic SelfDemonstrating/TheJoker and Penguin teamed up and were so good with their combined resources that Batman was powerless to stop them. He won only after they had captured him and he turned them against each other by stroking their egos to the point that they got into a competition and then an argument over who was contributing more to their partnership.
* One of the earliest examples has to be the Injustice Society of the World who first fought the JusticeSocietyOfAmerica in ''All Star Comics'' #37 in 1947, when the concept of supervillains was still relatively new. They would return (in different incarnations) to plague the JSA over the decades.
* Media adaptations of the Comicbook/{{X-Men}} have an annoying habit of grouping most X-Villains as members of the Brotherhood of (Evil) Mutants with SelfDemonstrating/{{Magneto}} as the leader, regardless of whether or not said villain ever had anything to do with the group in the comics (Sabretooth, Emma Frost, and the Juggernaut, who's not even a mutant), or if they'd ''ever'' play second fiddle to ''anyone'' (Mystique, who led her own version of the team).
** Funnily enough, Mystique and Sabretooth, the ones most likely to be on Magneto's side in these adaptations despite almost never being so in the (mainstream) comics, are still associated with ''another'' evil ComicBook/{{X-Men}} team- [[MadScientist Mister Sinister]]'s Marauders, who are a lot less picky about who to team up with. Though he [[ChronicBackstabbingDisorder probably won't be in any hurry to rehire Mystique anytime soon.]]
* DC's Injustice Gang pretty much embodies this trope. The antithesis to the Justice League, they're a group of villains who band together to destroy the JLA. The lineup changes with every appearance, since the Gang tends to disband (or all be thrown in jail) at the end of a given story. Its most successful incarnations have all been led by Lex Luthor, perhaps due to his GenreSavvy nature; in one story, he tells his fellow members "let's not fall victim to the cliche of the villains who can't get along." He's also perhaps the only major supervillain who has been able to successfully enforce harmony and cooperation among his gang, with no dissensions, betrayals, or serious infighting -- no small feat when you've got The Joker on your team.
* Speaking of Lex and the Joker (back when he was NeutralEvil rather than ChaoticEvil), they teamed up during TheSilverAgeOfComicBooks to take on Bats and Superman, by robbing Fort Knox with ''nigh-invulnerable robots''. [[CutLexLuthorACheck Why in the nine hells they didn't just sell the robots and retire to a Caribbean island is anyone's guess]].
** As the Joker would say: Where's the fun in that?
* The EvilCounterpart to the Comicbook/{{Legion Of Super-Heroes}}, the Legion of Supervillains, especially the latest incarnation, led by [[Franchise/{{Superman}} Superboy]]-Prime, wherein the roster consists of almost all of the villains the Legion ever faced.
* The UrExample is the Monster Society Of Evil, who fought [[Comicbook/{{Shazam}} the original Captain Marvel]] from 1943 to 1945 in one long, continuous story. It was led by the new villain Mister Mind, but was composed mostly of villains that the good Captain had fought before. And the entire Axis Powers.
* In fact the first example may be from Leading Comics #1 (winter 1941) where the Seven Soldiers Of Victory formed. Master Criminal the Hand, thinking he will die soon, organizes five other criminals to use five unused schemes of his, referring to them as the Hand's Five Fingers. They are stopped by various heroes leading to the formation of the Soldiers. Interestingly enough one member, the Dummy, was a member of the first Monster Society.
* In ''Comicbook/{{Ghost Rider}}s: Heaven's on Fire'', a Legion of Doom has been assembled to kill the Ghost Riders, consisting of Blackout (murderous vampire), the Deacon (musclebound religious zealot with sacred knives), the All-New Orb (LegacyCharacter to the original Ghost Rider archvillain), Big Wheel (baddie-for-hire who pilots a large metal wheel), Madcap (indestructible lunatic with contagious insanity), Vengeance (ex-cop turned Ghost Rider simulacrum), Trull the Inhuman (alien-possessed steamshovel), and Scarecrow ([[Franchise/{{Batman}} No, not that one]], but rather a maniac with a pitchfork who commands crows).
* Marvel has several: [[Comicbook/TheAvengers The Masters of Evil]], [[Franchise/SpiderMan the Sinister Six]], Hood's Gang, [[Comicbook/FantasticFour The Frightful Four]], etc.
** The Masters of Evil are the most successful, with one incarnation taking over the Avengers' base (and beating the living crap out of Hercules and Jarvis). Much of this incarnation later went on to form the {{Thunderbolts}}. (Hercules, amongst others, was ''not'' happy to find out about this...)
** The Lethal Legion in one incarnation was an ArchivedArmy.
** And the Legion of the Unliving, which is made of characters currently dead, and in one incarnation was mostly made up of dead Avengers.
** The Sinister Six has even become the Sinister Twelve.
** The Council of Kangs is made entirely of [[ConquerorFromTheFuture Kang the Conqueror]] and his various iterations created by time travel.
* A particularly enjoyable miniseries example came from Marvel a few years ago: {{MODOK}}'s [[{{Parody}} 11]]. MODOK hires a group of supervillains to help him steal a MacGuffin. 3/4 of the team ends up being traitors, moles and sellouts. In the end, [[spoiler: it was all just a [[GambitRoulette ridiculously circuitous plot]] to get revenge on his ex-girlfriend.]]
* ''TheFlash'' has The Rogues, who started out as a VillainTeamUp in TheSilverAgeOfComicBooks, but after discovering how well they worked together decided to keep working together. These days it's rare to see one of the Rogues commit a crime without some of the others around.
* Comicbook/FallOfTheHulks gave us the Inteligencia, a group of Marvel's smartest villains. Unlike most examples, they've managed to not fall to bickering and work towards a common goal.
* The Superman Revenge Squad, mostly made up of relatively minor or recently created Franchise/{{Superman}} villains, was formed by behind-the-scenes bad guy Morgan Edge to fight Superman. The group ultimately failed due to a lack of cohesion.
* An early Superman story had the Terrible Trio, made up of Lex Luthor, the Toyman, and the Prankster.
* In ''TopTen'', it's established that what would be supervillain teams anywhere else are essentially street gangs in Neopolis, where ''everybody'' is super. There's an ongoing turf war between the Fabulous Five and the League of Evil.
* As part of his plans during ComicBook/DarkReign, NormanOsborn set up a "Cabal" consisting of himself, [[ComicBook/{{X-Men}} Emma Frost]], [[Comicbook/SubMariner Namor]], SelfDemonstrating/DoctorDoom, TheHood, and ComicBook/{{Loki}}. It...uh...[[HumiliationConga worked out about as well as for Osborn as everything else did in that saga]].
** But there was also a DarkAvengers, with villains impersonating heroes.
** Norman tries again when he busts out of jail following ''Comicbook/FearItself'', this time allying his H.A.M.M.E.R. organization with A.I.M., Hydra, and the Hand, and once again uniting multiple villains (independent of those groups) into a new group of Dark Avengers. It doesn't work out for him any better this time.
* Image's ''Guarding the Globe'' series introduced us to the Order, a select group of minor recurring ''ComicBook/{{Invincible}}'' villains, including the Face, Master Liu and his bodyguard, Octoboss, Multi-Paul, Machine Head, Isotope, and Titan -- in addition to new guys like the group's leader Set, his woman Embrace, and international enforcers like Red Eye, Insomniac, Slaying Mantis, the Walking Dread...and [[spoiler:War Woman.]]
* In ''ComicBook/AllFallDown'', the Order of Despots is this to the Pantheon.
* ''ComicBook/LeagueOfExtraordinaryGentlemen'' had two, which were formed by France and Germany in the early 20th century to combat Britain's original League. The French had "Les Hommes Mysterieux" ("The Mysterious Men"), which included Literature/ArseneLupin, [[http://en.wikipedia.org/wiki/Robur_the_Conqueror Jean Robur]], Literature/{{Fantomas}}, [[http://en.wikipedia.org/wiki/Nyctalope the Nyctalope]] and [[http://en.wikipedia.org/wiki/Monsieur_Zenith Monsieur Zenith]]. The Germans had "Die Zwielichthelden" ("The Twilight Heroes"), which included [[Film/TheCabinetOfDrCaligari Dr. Caligari and his assassin Cesare]], [[Film/{{Metropolis}} Dr. Rotwang and his robotic servant Maria]], and Literature/DoctorMabuse. Both groups had a hand in starting the ''League'' universe's version of WorldWarI.

[[folder:Fan Works]]
* The Guild of Super Evil from FanFic/Hottie3TheBestFanFicInTheWorld.
** The Empire of Darkness from the sequel, [[http://alaxr274.deviantart.com/gallery/46993107 Hottie 4: Even Better Sequel]]. Members include the TropeNamers themselves.
* In ''[[FanFic/MyLittleMagesTheNightmaresReturn My Little Mages: The Nightmare's Return]]'', Nightmare Moon assembles a team of [[WesternAnimation/MyLittlePonyFriendshipIsMagic FiM]] antagonists as her mooks, including Chrysalis (a necromancer), the Diamond Dogs (werewolves) and Iron Will (a mercenary).
* ''FanFic/InvaderZimTheSeries'': During the last StoryArc, Tallest Spork assembles most of Zim's RoguesGallery for the combined goals of killing Zim and taking over the Irken Empire.
* Often times in ''Pooh's Adventures'', there's a legion of assorted villains that are after Pooh, and there are times in the Adventures where the good chunk of them are featured as the main villains that team up with the villain of the film.
* ''FanFic/TheBridge'' gives us the currently unnamed [[BiggerBad BiggerBad's]] posse that also works as a [[{{Kaiju}} Genre Crossover]] with evil kaiju from numerous franchises. Gigan, Gaira, Megalon, Hedorah, Monster X, and King Ghidorah from {{Franchise/Godzilla}}, Gyaos (Normal, Super, and an albino Hyper) and Legion from {{Franchise/Gamera}}, and Leatherback, Otachi, Knifehead, and Slattern from ''Film/PacificRim''. Most parties joining him for the sole purpose of getting what they want most, which is not pleasant (feasts, destruction, conquest, etc.)
[[/folder]]

[[folder:Film]]
* The 1966 live-action ''Film/BatmanTheMovie'', featuring the Joker, the Penguin, the Riddler, and Catwoman ("United Underworld") in a cheesy [[spoiler: [[EverythingsBetterWithPenguins penguin-shaped]]]] submarine. They even went through the trouble of making a logo.
** [[EverythingsSquishierWithCephalopods An octopus]] [[GotTheWholeWorldInMyHand strangling a globe?]]
* The Joel Schumacher-directed Batman movies also have this as all the villains within the movie unite to kill Batman. Riddler joins and eventually leads Two-Face's gang in ''Film/BatmanForever'' and Mr. Freeze allies with Poison Ivy and Bane in ''Film/BatmanAndRobin''. More or less subverted in ''Film/BatmanReturns'' where Penguin's two allies have no idea they're both affiliated with Penguin (at least on a criminal level) and none of them can get past the second act without completely and violently falling apart.
* Done in ''WesternAnimation/{{Shrek}} 3'' with fairy tale villains.
* ''Film/ScoobyDooMonstersUnleashed'', reviving many of the {{monster|OfTheWeek}}s that Mystery Inc. has unmasked in the past. However, this time, all of them are ''real''.
* In ''Film/NightAtTheMuseum 2'', Kahmunra recruits NapoleonBonaparte, Ivan The Terrible, and AlCapone as his evil [[ArchivedArmy team]]. [[Franchise/StarWars Darth Vader]] and [[Series/SesameStreet Oscar the Grouch]] also try to join it.
* ''Film/LooneyTunesBackInAction'' had various Looney Tunes antagonists (Elmer Fudd, Yosemite Sam, Marvin the Martian, etc.) working for the BigBad.
* ''Film/TheAmazingSpiderManSeries'' is building up to Spider-Man having to face one.
* In ''Film/KickAss2'', The Motherfucker assembles a bunch of killers and dresses them up as supervillains to counter the rise of superheroes.
[[/folder]]

[[folder:Literature]]
* ''Literature/AnnoDracula'' features a Legion of Doom comprising Franchise/FuManchu, [[Literature/SherlockHolmes Professor Moriarty, Colonel Moran]], Literature/{{Raffles}}, Literature/TheInvisibleMan, [[Theatre/TheBeggarsOpera Macheath]] and [[Literature/OliverTwist Bill Sikes]]. In a twist, they [[EnemyMine join forces with the heroes]] to stop [[JackTheRipper the Silver Knife]], because EvenEvilHasStandards...or at least, good business practices.
* Harry Dresden of ''Literature/TheDresdenFiles'' names the [[TheManBehindTheMan shadowy force]] the Black Council so as to not call it this trope. He also calls it a [[Franchise/StarWars phantom menace]] at one time, but [[ShoutOut asks forgiveness for the phrasing]].
* The Dark Forest in ''Literature/WarriorCats'' is a group of all the evil cats from earlier books, joining their forces to destroy the Clans.
[[/folder]]

[[folder:LiveActionTV]]
* ''Series/{{Smallville}}'' did this at least once.
* The final episode of ''Series/TeamKnightRider'', aptly titled "Legion of Doom", featured all the villains from the series teaming up under the command of the series' BigBad.
* ''Series/DoctorWho'' has toyed with doing this on several occasions, but it never quite works out.
** In [[Recap/DoctorWho20thASTheFiveDoctors "The Five Doctors"]], many of the Doctor's worst foes are brought together to finish him off -- but they are merely pawns of TheManBehindTheCurtain, and apart from the Master and the Cybermen don't even interact.
** [[Recap/DoctorWhoS3E4TheDaleksMasterPlan "The Daleks' Master Plan"]] is nearly an ideal example of the trope -- a colourful array of supervillains is brought together by the Daleks; it includes a dominant, disruptive personality (YellowPeril and DiabolicalMastermind Mavic Chen), and the heroes exploit the infighting. Just one problem -- the Doctor's never met any of these bad guys before.
** The new series episode [[Recap/DoctorWhoS28E13Doomsday "Doomsday"]] bring the Daleks and Cybermen together, however the Daleks, being the Daleks, respond to the Cybermen's offer of an alliance with summary extermination.
** Subverted to hell and back in [[Recap/DoctorWhoS31E12ThePandoricaOpens "The Pandorica Opens"]], in which a couple ''dozen'' races show up, apparently to squabble over whatever is imprisoned in the eponymous device, [[spoiler:only to imprison the Doctor in an effort to ''save'' the universe.]] Seen on screen are the Daleks, the Cybermen, the Sontarans, the Silurians, the Autons, and the Judoons, and many more get name checks or cameos in crowd shots.
* Done at least twice in ''Franchise/PowerRangers''. Once with ''[[Series/PowerRangersInSpace In Space]]'' with [[BigBad Dark Specter]]'s United Alliance Of Evil (rounding up six seasons' worth of villains), and again in the ''[[Series/PowerRangersOperationOverdrive Operation Overdrive]]'' 15th anniversary "Once A Ranger" 2-parter, with the never-seen-before son of [[Series/MightyMorphinPowerRangers Rita Repulsa and Lord Zedd]] uniting the season's BigBadEnsemble (who are usually at each other's throats in any episode involving more than one organization.)
* ''Series/KamenRiderDecade'' introduces a particularly large version in the form of Great Shocker, which is an alliance of every single evil organization from ''Franchise/KamenRider''[='=]s 30-plus-year history united under a single banner and dedicated to conquering the multiverse and destroying all the Kamen Riders. [[spoiler:And their leader is Tsukasa Kadoya, AKA Kamen Rider Decade, one of --- if not --- ''the'' most powerful Rider ever.]] In ''[[GrandFinale Final Chapter]]'', [[spoiler:following Great Shocker's downfall in ''All Riders vs. Great Shocker'', Doctor Shinigami and Narutaki (who reveals himself as Colonel Zol) gather TheRemnant as Super Shocker, hoping to take advantage of the fact that Tsukasa's rampage as Destroyer of Worlds has eliminated all the Kamen Riders. Unfortunately for them, all the Kamen Riders are later brought BackFromTheDead ''because'' Decade destroyed them (it's a complicated story).]] In ''Film/KamenRiderXSuperSentaiSuperHeroTaisen'', Great Shocker has been rebuilt with its leader back into the seat and [[Series/KamenRiderV3 Doctor G]] as his [[TheDragon Dragon]], for a new purpose: the systemic annihilation of all the Super Sentai teams, simply because the Zangyack Empire decided to step on the ''Kamen Rider'' multiverse's toes --- see the ''Series/KaizokuSentaiGokaiger'' section below for their side of the story.
** In a smaller scale, the final episode sees Apollo Geist reviving some of the {{monster|OfTheWeek}}s that Tsukasa and company dealt with while travelling through the AR worlds.
** The [[MilestoneCelebration 40th anniversary movie]] ''[[Film/OOODenOAllRidersLetsGoKamenRiders Let's Go Kamen Rider]]'' has Shocker [[BadFuture persisting into the 21st century]] thanks to [[Series/KamenRiderOOO Ankh]] sneaking into [[Series/KamenRiderDenO Den-O]]'s time-traveling train [[ForWantOfANail for want of medals]]; its membership in 2011 includes villains from all over the franchise like [[Series/KamenRiderBlackRX General Jark]] and [[Series/KamenRiderDouble Ryubee Sonozaki/Terror Dopant]].
* The OnTheNext preview for episode 25 of ''Series/KamenRiderFourze'' teased at this, where three previous Zodiarts that Fourze had already defeated seemed to have regained their powers, and are working together to sabotage the school prom. [[spoiler:However, it turns out that this was just the work of a Zodiarts whose power is to create copies of previous Zodiarts.]]
** In the ''[[Film/KamenRiderXKamenRiderFourzeAndOOOMovieWarMegaMax Movie War]]'' {{crossover}} with ''Series/KamenRiderOOO'', Foundation X uses the research its agents gathered to build an army consisting of various {{monster|OfTheWeek}}s as well as mooks from the three series involved (''Fourze'', ''OOO'' and ''[[Series/KamenRiderDouble W]]''), alongside monsters of the BigBad's own design, called "Mutamids". They are not essentially the same monsters from their original series, but it's an excuse to reuse monster suits.
* In the ''[[Film/KamenRiderXKamenRiderWizardAndFourzeMovieWarUltimatum Movie War]]'' between ''Fourze'' and ''Series/KamenRiderWizard'' there is Monster Army, which consists of revived [[Series/KamenRiderDouble Dopants]], [[Series/KamenRiderOOO Yummy]], [[Series/KamenRiderFourze Zodiarts]], and [[Series/KamenRiderWizard Phantoms]], led by Akumaizer3.
** The final episodes of ''Wizard'' also sees the heroes dealing with an army of monsters from the previous Heisei series.
* The final episodes of ''Series/KamenRiderDenO'' features the BigBad amassing an enormous army of the series' MonsterOfTheWeek in order to outnumber the heroes (two Riders and 5/6 Imagin) and accomplish his plans. This army would later be resurrected in the third movie, ''Final Countdown'', under the movie's BigBad.
* Not wanting to be left out, there is the [[MilestoneCelebration 30th anniversary celebration]] ''Series/GoGoSentaiBoukenger vs. Franchise/SuperSentai'', where High priest Gajah makes an alliance with the movie's BigBad, Chronos, who in turn revives [[Series/HyakujuuSentaiGaoranger Tsue Tsue]], [[Series/MahouSentaiMagiranger Meemy]] and, in the very last minute, [[Series/NinpuuSentaiHurricaneger Furabijo]]. [[spoiler:Last minute, as in the alliance was quickly short-lived, by Chronos betraying everyone and turning the three sorceresses into a staff to power himself up.]]
* The movies for the ''35th'' anniversary series do something similar - ''Series/KaizokuSentaiGokaiger'' is already a Decade-style-celebration, but its villains are the completely original Zangyack Empire. However, the [[Film/GokaigerGoseigerSuperSentai199HeroGreatBattle first movie]] involves said empire making an alliance with the Black Cross King, a revived [[PeopleInRubberSuits rubber suit]] form of the Black Cross [[NoSwastikas Fuhrer]] from ''Series/HimitsuSentaiGoranger'', who in turn revives [[Series/TensouSentaiGoseiger Brajira]] and a number of villains from ''Series/MahouSentaiMagiranger'' and ''Series/EngineSentaiGoOnger''.
** Among the lackeys of the villain of ''Film/KaizokuSentaiGokaigerTheMovieTheFlyingGhostShip'' is a revived [[Series/TokusouSentaiDekaranger Agent Abrella]], who himself leads an army of nearly every {{Mook|s}} that has existed in ''Sentai'' history.
** In ''Film/KamenRiderXSuperSentaiSuperheroTaisen'', Zangyack has been expanded into "Great Zangyack" by the hands of their new emperor, [[spoiler:who appears to be a {{Face Heel Turn}}ed Captain Marvelous, AKA Gokai Red, who launches an invasion of the ''Kamen Rider'' multiverse to claim the Riders' Grand Powers]]; its membership includes a number of high-level villains from all over the ''Super Sentai'' franchise like [[Series/SamuraiSentaiShinkenger Doukoku]] and [[Series/ChoudenshiBioman Bio Hunter Silva]].
* ''Series/{{Angel}}'' Season 5 makes use of this by taking several minor characters that appeared throughout the season and putting them in a group called the Circle of the Black Thorn, which the heroes spend the last episode combating. Sort of an {{inver|tedTrope}}sion--rather being a group of random villains that teamed up, they had ''already'' been working together, though Angel and his friends didn't find out until later.
* In the first season of ''Series/{{Blackadder}}'', Prince Edmund gathers the six most evil men in England to help him take over the kingdom. However since he doesn't really belong among their number, much less [[BigBadWannabe leading them]], they quickly betray him for a more fitting leader.
* Sue's self-described Leg - uh, ''League'' of Doom in ''Series/{{Glee}}'', if you replace "supervillain" with "returning character with a grudge against the local show choir". She even gives them code-names, dubbing herself [[KneelBeforeZod General Zod]].
[[/folder]]

[[folder:Music]]
* ''Chester'', a now-classic William Billings song from the Revolutionary War, devotes a verse to what sure sounds like the British Legion of Doom circa the 18th Century.
-->''Howe and Burgoyne and Clinton, too''
-->''With Prescott and Cornwallis joined,''
-->''Together plot our overthrow''
-->''In one infernal league combined.''
[[/folder]]

[[folder:ProfessionalWrestling]]
* Legendary ProfessionalWrestling stable The Four Horsemen started out as a Legion of Doom-esque gathering of {{heel}}s. Rated RKO was the teaming of two of [[Wrestling/DGenerationX DeGeneration X]]'s biggest rivals, and [=DeGeneration X=] itself was originally formed to fight against The Hart Foundation. There is also was a wrestling group called Wrestling/LegionofDoom, who existed three years before the Horsemen but had been reduced to a tag team when the Horsemen showed up. And we can't let the Pro Wrestling entry go by without a mention of the [[Wrestling/NewWorldOrder nWo]], can we?
* While LOD might have been best known as the tag team of Hawk and Animal, in Georgia Championship Wrestling they were actually an example of this trope and included such other future legends as [[Wrestling/JakeRoberts Jake the Snake]], The Spoiler, Matt Borne (AKA the first Wrestling/DoinkTheClown), Wrestling/KingKongBundy, Wrestling/ArnAnderson, and for perhaps the only time both of the Sheiks, [[Wrestling/TheIronSheik Iron]] and [[Wrestling/EdFarhat Original]]. The two remaining members were made into a tag team and were supposed to be called Wrestling/TheRoadWarriors hence why they are introduced as "Road Warrior Hawk" and "Road Warrior Animal". The two names have been used interchangeably since then.
* In 1995 Wrestling/{{WCW}}, Wrestling/KevinSullivan and his "Father" The Master (Wrestling/KingCurtisIaukea) put together one of the most imposing heel stables of all time called the Wrestling/DungeonOfDoom. The group featured the great [[WrestlingMonster Monster Heels]] Wrestling/{{Kamala}}, [[Wrestling/JohnTenta The Shark (John "Earthquake" Tenta)]] and Haku (now known as Wrestling/{{Meng}}) who is generally considered one of if not the most legitimate tough guys in wrestling also joined the group, with the centerpiece being [[Wrestling/TheBigShow The Giant]]. At Halloween Havoc 95 the group really began to hit its stride with the inclusion of former world champion Wrestling/LexLuger and the legendary Manager Wrestling/JimmyHart. The stable would expand over the next several months to include an odd mix of characters, including Wrestling/TheBarbarian, [[Wrestling/RonReis The Yeti]], Wrestling/TheOneManGang, Wrestling/GiantHaystacks (billed as the Loch Ness Monster) [[Wrestling/BigBossman Big Bubba (Ray "The Big Bossman" Traylor)]], Wrestling/HughMorrus, Wrestling/{{Jacqueline}} and Wrestling/{{Konnan}}. The stable peaked in early 1996 and were ultimately DemotedToExtra due to the rise of the [[Wrestling/NewWorldOrder NWO]] and dissolved after Wrestling/ChrisBenoit d. Sullivan in a "Career vs. Career" match at ''Bash at the Beach'' on July 13th, 1997.
* During ''Uncensored '96'', two of the groups above united to create an even ''bigger'' Legion of Doom when the Four Horsemen and the Dungeon of Doom joined forces to become the Alliance to End Hulkamania along with two random wrestlers The Ultimate Solution (the late Robert "Jeep" Swenson, aka "Bane" from ''Film/BatmanAndRobin'') and Z-Gangsta (Tom Lister, Jr., who played Zeus in Wrestling/HulkHogan's 1989 film ''Film/NoHoldsBarred''). They fought Hogan and Wrestling/RandySavage in the "Doomsday Cage Match", a triple-decker cage. However, at the apex of his InvincibleHero status, Hogan was still too much for the eight members of the Alliance and he and Savage soundly beat them.
* Wrestling/MsChif briefly had one in the form of Amazing Kong (whom she feuded with in the Wrestling/{{N|ational Wrestling Alliance}}WA), Wesna Busic (whom she fell to in the Chick Fight VIII finals) and Wrestling/SaraDelRey (who she beat for the Wrestling/{{SHIMMER}} championship). Wesna backed off after being beaten while Kong came and [=MsChif=] [[WorthyOpponent eventually came to a mutual understanding]] ([=MsChif=] later tried to fight Kong's own legion of doom). Also, Ashley Lane, Nevaeh and Wrestling/CheerleaderMelissa were there to back [=MsChif=] up (back up meaning [[NoHoldsBarredBeatdown sharing the beating]])
* SHINE's founders attempted to curb the chaos pro wrestling often devolves into by giving [[EasilyDistractedReferee ref]][[GlassJawReferee erees]] power to fine and suspend. Most wrestlers were apathetic but repeat offenders Radiant Rain and Made In Sin(Allysin Kay-Taylor Made-April Hunter) took exception to this upstart promotion docking their pay and bookings. So they formed "Valkyrie" with new comer Ivelisse Vélez to subvert SHINE's rulings and [[EvilIsPetty freely target wrestlers on its roster]], starting with [[Wrestling/KiaStevens Amazing Kong]], who broke Rain's wrist after [[Wrestling/CarleneMoore Jazz]] [[NiceJobBreakingItHero lobbied to end the suspensions of Rain]] and Wrestling/MercedesMartinez, [[SeriousBusiness to get them in a tag team match]].
* [[Wrestling/BryanDanielson Daniel Bryan]] had his own personal legion of doom in the form of Triple H, Wrestling/RandyOrton, Stephanie [=McMahon=], Wrestling/TheShield (Wrestling/SethRollins, Wrestling/RomanReigns and Wrestling/DeanAmbrose), The Big Show and former [[Wrestling/TeamHellNo tag team partner]] Wrestling/{{Kane}}. They didn't really want eliminate Daniel Bryan the way most examples of this trope do, they just wanted to keep him from becoming the WWE Champion, which they succeeded in, time and time again until WWE realized just how much people wanted to see Daniel Bryan win and finally threw him a bone, only to see him get injured and [[TheBadGuyWins written off TV via choke slam from Kane]].
* The Flood, an alliance gathered together from across time and space, featuring Milo Schnitzler, Jigsaw, Haack, Slaash, Dr. Cube's (from Wrestling/KaijuBigBattel) Posse ([[ReverseMole just Cube actually, the others were fakes]]), [[CircusOfFear Sinn Bodhi]]'s Odditorium (Bodhi, Qefka the Quiet, Oliver Grimsley), [[EvilForeigner The BDK]] (Ares, Tursas, [[Wrestling/HunterJohnston Delirious]], Nřkken), [[DiscoDan Sidney Bakabella]]'s Wrecking Crew (Bakabella, Max Smashmaster, Blaster [=McMassive=], Oleg The Usurper, Jaka, Flex Rumblecrunch), GEKIDO (The Shard, 17, [=DeviANT=], [=CombANT=], [=AssailANT=]) and Colony: Xtreme Force (Missile Assault Ant, Arctic Rescue Ant, Orbit Adventure Ant) the latter two both being PsychoRangers to the Colony, Jigsaw and Wrestling/MikeQuackenbush(yes, Jigsaw was on the same team as someone setup specfiically to take him down). They were brought to aid Wrestling/JimmyJacobs, who in turn was working for [[TheManBehindTheMan Deucalion, The Titan of Titor]], in his efforts to kill off Wrestling/{{Chikara}}, which they nearly did, for the better part of a year.
[[/folder]]

[[folder:Tabletop Games]]
* There's a sort of example done apparently just for the sake of simplicity in the games ''Hero Quest'' and ''Space Crusade'', roughly based on ''{{TabletopGame/Warhammer}}'' and ''{{TabletopGame/Warhammer 40000}}'', respectively. In both games the bad guys are ostensibly "Chaos", but in fact their units are a combination of Orc, Undead and Chaos / Ork, Tyranid, Chaos Android and Chaos Space Marines characters, all united under the control of the same player to destroy humanity.
* ''TabletopGame/VillainsAndVigilantes'' has an introductory adventure, "Crisis at Crusader Citadel," which has an NPC hero team, the Crusaders, and the Crushers, a villain team made up of their archenemies. Although it only points out who a few of the feuds are between.
[[/folder]]

[[folder:Theatre]]
* The stage play ''Series/DoctorWho: The Ultimate Adventure'' uses this trope, combining Daleks and Cybermen for the first time (outside of "The Five Doctors," when the Dalek basically cameos), although the two sides (not surprisingly) end up feuding.
** Technically, the earlier stage play ''Doctor Who & the Seven Keys to Doomsday'' also uses the trope, combining Daleks with Clawrentulars, but since the latter have not appeared before or sense, they amount more to henchmen and one-off baddies.
[[/folder]]

[[folder:Theme Parks]]
* The Sinister Syndicate in ''Ride/TheAmazingAdventuresOfSpiderMan'', which consists of Doctor Octopus, Hobgoblin, Electro, Hydro-Man, and Scream.
* The ''Theatre/{{Fantasmic}}'' water/light show at [[Ride/DisneyThemeParks Disneyland]] has a (rather tenuous) storyline where Mickey Mouse's dreams are being haunted by a team-up of [[Disney/SnowWhiteAndTheSevenDwarfs Queen Grimhilde]], [[Disney/TheLittleMermaid Ursula]], [[{{Disney/Fantasia}} Chernabog]], and [[Disney/SleepingBeauty Maleficent]]. In the Disney Hollywood Studios (formerly Disney MGM Studios) version, they're joined by [[Disney/OneHundredAndOneDalmatians Cruella de Vil]], [[Disney/{{Aladdin}} Jafar]], [[Disney/TheLionKing Scar]], [[Disney/TheHunchbackOfNotreDame Frollo]], and [[Disney/{{Hercules}} Hades]].
[[/folder]]

[[folder:Video Games]]
* In ''VideoGame/KingdomHeartsI'', various [[Franchise/DisneyAnimatedCanon Disney Villains]] banded together under the command of Maleficent from ''Disney/SleepingBeauty''. As with most of the (relatively rare) video game cases, the villains didn't turn on each other; instead, the heroes [[SortingAlgorithmOfEvil picked them off one by one]]. Though Maleficent was the leader and the last required to fight, Hades was actually the most powerful (being a god and all) and thus, fighting him was left entirely optional until ''VideoGame/KingdomHeartsII''.
** [[spoiler: A few games later, after more and more counterparts of [[BigBad Xehanort]] have shown up, there's an entire council of Xehanorts.]]
* The premise of ''VideoGame/NicktoonsUnite'' is that [[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy Neutron]]'s nemesis Professor Calamitous steals his plans for a dimensional portal to form an "Evil Syndicate" consisting of him, [[WesternAnimation/DannyPhantom Vlad Plasmius]], [[WesternAnimation/SpongebobSquarepants Plankton]], and [[WesternAnimation/TheFairlyOddParents Mr. Crocker]]. Naturally, Jimmy pulls the reverse and just like the first ''Kingdom Hearts'' mentioned above, you pick them off one by one 'till the pseudo-BossRush climax. And despite all four members being captured at the end, the syndicate reappeared three games later in ''Globs of Doom'' but with a different lineup of four (Plankton being the only "veteran" out of them) and ''only serving for a EnemyMine situation'' (Well, until the SnapBack). Nevertheless, both incarnations never got to infighting at all.
* ''VideoGame/DissidiaFinalFantasy'' has a Legion made up of the main bosses from the first 10 ''Franchise/FinalFantasy'' games, headed by the god Chaos, and opposed by the heroes of the same. They're not exactly the most cooperative of groups: They seem to have split between the [[OmnicidalManiac Destroyers]], [[TheChessmaster Schemers]], [[HeelFaceTurn Defectors]], and those who are just plain following their own agenda. But really, that's what you get when you assemble people that are ''this'' unhinged and expect them to get along.
* In ''VideoGame/SuperSmashBros Brawl''[='=]s Subspace Emissary story mode, a group of villains, including playable characters Bowser, Ganondorf, and Wario, and [=NPCs=] Petey Piranha, Porky, and Ridley join under Master Hand, [[spoiler: who is secretly being controlled by Tabuu]], to make the Subspace Army. Bowser, Ganondorf, and Wario all end up eventually betraying the army, joining the heroes [[spoiler: once they realize they were just Tabuu's pawns.]] However, Ganondorf planned on overthrowing Master Hand and becoming the army's leader long [[spoiler:before he learned of Tabuu.]]
* ''VideoGame/MarvelUltimateAlliance'' features a virtual army of supervillains forming a new Masters of Evil, as well as several cutscenes in which Doctor Doom plot his evil schemes along with his flunkies, er, allies, Loki, the Enchantress, Baron Mordo, and Ultron (one assumes Ultron was frequently pinched for forgetting to wear green).
* The Black Cloak Society of ''VideoGame/KingsQuest'' was ''designed'' as a passing mention in an incriminating letter for the sixth game. However, the way the letter's worded implies that at least three of the series' {{Big Bad}}s were part of the society...and possibly ''all of them'' were either members or allied with them. The FanRemake of the second game and the FanSequel have run with the "possibly all of them" theory.
* In ''VideoGame/SuperRobotWars2'', Bian Zoldark created the Divine Crusaders using the combined might of [[Anime/MobileSuitGundam the Principality of Zeon]], [[Manga/GetterRobo the Dinosaur Empire]], and [[Anime/MazingerZ Dr. Hell's Mechanical Monsters]]. When Bian died, the Zabi family took over as the Neue DC and added new forces. However, unlike Bian's DC, the Zabi's version fell apart just as bad as it did with normal Zeon and by the fourth game, the only one of the original three still active was Dr. Hell!
* In ''VideoGame/ViewtifulJoe'', the bad guys are an evil organization of all of Captain Blue's old villains, who have taken over since his defeat and living the life. [[spoiler:Turns out that it was Captain Blue himself who was their boss!]]
** And in the sequel, another evil organization takes their place, whose roster includes [[TheRival Alastor]] from the first game and Fire Leo's brother, Frost Tiger, [[spoiler:and is run by Joe's father, who's been corrupted by the Black Film and the Black V-Watch.]]
* ''VideoGame/MarvelAvengersAlliance'' has most of Marvel's supervillains from Hydra to the Brotherhood of Mutants uniting and forming the Syndicate; their goal is to harness [[GreenRocks Iso-8]] (which is capable of enhancing people's powers) and take over the world.
* In the ''VideoGame/WorldOfWarcraft'' expansion ''Cataclysm'', several previously unrelated factions that were fought many times in the game team up under the rule of [[OmnicidalManiac Deathwing]] and the [[EldritchAbomination Old Gods]] to fight the Alliance and the Horde: the [[TheRemnant Dark Horde]], the [[EvilCounterpartRace Dark Iron Clan]], the [[SnakePeople naga]], the [[{{Cult}} Twilight's Hammer]], the [[AlwaysChaoticEvil black dragonflight]], the [[MakeWrongWhatOnceWentRight infinite dragonflight]], the [[ElementalEmbodiment air and fire elementals]], and the [[{{Cthulhumanoid}} Faceless Ones]].
[[/folder]]

[[folder:Webcomics]]
* The [[http://www.shortpacked.com/d/20081219.html Axis of...Something]] in ''Webcomic/{{Shortpacked}}'', comprising the guy who insists disagreeing with him makes Ethan "arrogant", Walter Mondale (seeking revenge on Reagan) and Faz. Their leader is a character who was fired from the store in her first appearance and has been plotting revenge ever since (ironically, this was what convinced Robin that nothing significant ever happened at Shortpacked, since none of the important characters were fired. Guess she really shouldn't have [[CerebusSyndrome pulled that drama tag]]).
* ''Webcomic/TheCrossoverlord'' assembled one of these by gathering enemies of each story's main characters -- at least one for each hero, two in the case of Webcomic/{{Dasien}}, but none for Webcomic/TheGreenAvenger (maybe because her only enemy at the point was a walking alarm clock, or [[spoiler:because she was brainwashed]]).
* The [[http://www.galactanet.com/comic/view.php?strip=274 League of Recurring Antagonists]] in ''Webcomic/CaseyAndAndy''.
* In ''Webcomic/TheOrderOfTheStick,'' the Inter-Fiend Cooperation Commission is an alliance of the three fiendish races (demons, devils, and daemons), who have traditionally competed against each other. Different from most of the above cases because its three leaders were never actually seen prior to the team-up.
** However, one recurring secondary villain (Sabine) was revealed to be working for them covertly behind her boss/boyfriend's back, and another minor villain introduced during the same arc (Qarr) was recruited to serve them during their initial appearance.
* The Warriors of Darkness in ''Webcomic/EightBitTheater'', four villains assembled to be the opposite number to the Warriors Of Light.
** The Warriors Of Light probably count too, having a kill streak spanning several continents worth of genocide and the [[PhlebotinumKilledTheDinosaurs KT event]].
* The ''Series/DoctorWho'' fancomic ''Webcomic/The10Doctors'', apparently influenced by the lack of this trope in the series (see above), goes nuts with it. [[TheTrickster The Celestial Toymaker]] is working for [[AGodAmI Omega]]. The [[EnemyCivilWar Renegade Daleks]] are taking commands from [[EnemyWithout the Valeyard]]. [[MadScientist The Rani]] is assisting [[EnemyCivilWar Davros and the Imperial Daleks]], who are themselves controlling [[YouWillBeAssimilated the Cybermen]]. [[EvilCounterpart The Master]] is using the War Chief and the [[ProudWarriorRaceGuy Sontarans]] to form a massive fleet of Ice Warriors, Draconians, and many other aliens from the Doctor's past. And that's just for ''starters''.
[[/folder]]

[[folder:Web Original]]
* The [[DepartmentOfRedundancyDepartment Evil League of Evil]] in ''WebVideo/DoctorHorriblesSingAlongBlog'', led by Bad Horse and his terrible death whinny.
* Team Kimba of the Literature/WhateleyUniverse is viewing Elite League as this. They have fought the Young Turks twice before, and a lot of the Alphas, and Gold Stallion's gang. Now they're seeing a team made up some of the best of those groups.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/{{Superfriends}}'' fought the {{Trope Namer|s}} and the TropeCodifier.
* ''WesternAnimation/{{Batfink}}'' had in episode 96 out of 100 a conglomeration of villains brought together by Tough Macduff, Batfink's 'Oldest Foe', though this is his first appearance. They consist of Manhole Manny, Big Ears Ernie, Gluey Louie, Stupidman, Skinny Minnie, Whip Van Winkle, Old King Cruel, Cinderobber, Swami Salami, Party Marty, Beanstalk Jack, Queenie Bee, Sporty Morty, Roz The Schnozz, and, to add insult to injury, Hugo A Go Go, the mad scientist. They tell Batfink to be branded a coward and leave town on a train. However, Batfink caches them all in a fishnet.
* ''WesternAnimation/ThePowerpuffGirls'',
** The episode "Meet the Beat-Alls", which was also [[ShoutOut made almost entirely of]] [[Music/TheBeatles Beatles]] song references and visual idioms.
** Another episode has one brief part near the ending where to get revenge on Buttercup (for repeatedly attacking them all with no provocation to get teeth in a typical tooth fairy story), a bunch of villains get together and beat her down.
* ''WesternAnimation/KimPossible'', "A Sitch In Time" (''sic''), wherein the biggest villains join up in a TimeTravel scheme, and get double-crossed by Drakken's sidekick Shego.
* The last season of ''WesternAnimation/TeenTitans'', assembled by the [[Comicbook/DoomPatrol Brotherhood Of Evil]].
* The last season of ''WesternAnimation/{{Ben 10}}'' with the Negative Ten.
* ''WesternAnimation/JusticeLeague'' featured this thrice: the two versions of the Injustice Gang in the episodes "Fury" and "Injustice For All", and the Secret Society in the episode "Secret Society" (naturally, after the above comic). The sequel series, ''Justice League Unlimited'', had another such group, albeit ''much'' larger and better organized, the focus of its third-season arc; this group was unnamed, but was variously called the Legion of Doom and the Secret Society by fans. (Lex does refer to it as a "society" at one point.) The entire third season was basically a homage to the aforementioned ''WesternAnimation/{{Superfriends}}'', complete with [[spoiler:{{Darkseid}} showing up as the TrueFinalBoss to replace them.]]
** The creators have admitted that they considered the massive villain group in JLU to be the Legion of Doom (complete with "Darth Vader head base in a swamp"), and generally referred to the group as such when discussing it, [[ExecutiveMeddling but had been explicitly told by DC that they could NOT use the Legion of Doom term.]] This is why the group is never actually named in the show, and why Luthor's allusion to the group implies it's related to the prior Secret Society. Note that Grodd corrects Luthor and implies the group ISN'T just a larger Secret Society -- but then fails to provide an alternate term.
*** Interestingly, they ''were'' referred to as The Legion of Doom on the JLU Season 2 DVD box.
** ''Justice League'' also featured the Superman Revenge Squad, though they were not named as such.
** The original Secret Society was something of an inversion of this trope. Grodd uses his mental powers to make the heroes more irritable, causing them to give vent to grievances that they normally kept bottled up. This causes the dissolution of the League, much the same way that a normal Legion Of Doom will fall apart. Grodd even lampshades the common fate of Legions Of Doom, and seeks to avert it using trust-building exercises and training.
** The episode with the Justice Guild has the Injustice Guild, based on the Injustice Society.
** "Epilogue" briefly features the Iniquity Collective, a small collection of the [[WesternAnimation/BatmanBeyond future Batman's]] rogues ([[MyFriendsAndZoidberg and Parasite]]).
* As the name would imply, the Legion of Doom are featured as the main villains of ''WesternAnimation/JusticeLeagueDoom''.
* ''WesternAnimation/AquaTeenHungerForce'' subverts this trope in the episode "The Last One", in which the Mooninites gather all the..."[[SitcomArchNemesis villains]]"...that have appeared in the series to form a Legion of Doom. After the group's decimated because of its members' stupidity and annoyance with each other, the survivors dub themselves "Sunday Monday Tuesday Wednesday Thursday Friday Saturday" and launch an assault on the ATHF's home -- which, of course, [[ShaggyDogStory goes nowhere]].
* The enemies of ''WesternAnimation/DarkwingDuck'' join forces to become the Fearsome Five, ([[EvilCounterpart NegaDuck]], [[ShockAndAwe Megavolt]], [[PlantPerson Bushroot]], [[MonsterClown Quackerjack]], and [[MakingASplash Liquidator]]) forcing Darkwing to create his own team, the Justice Ducks in the episode "Just Us Justice Ducks".
* Used (And made fun of) in the Third Season Premiere Show of ''WesternAnimation/DuckDodgers'', where nearly every minor one-or-two-episode villain was brought together (Sometimes from the dead) to form the Legion of Duck Doom, as the primary antagonists, Mars, were currently at peace with Earth. (Though by the end of the episode, the Legion is defeated, and war breaks out again.)
** There was even a CaptainErsatz of the [[WesternAnimation/SuperFriends Black Manta]] called the Black Eel (who really shouldn't of been there, as he had no quarrel with Dodgers).
* The Council of Doom was the collective name of ''WesternAnimation/SpaceGhost'''s sworn enemies: Brak, Zorak, Moltar, Black Widow, Creature King, and Metallus.
** It should be noted that the Council of Doom appeared over a decade before the TropeNamer.
* In an episode of ''WesternAnimation/CourageTheCowardlyDog'', Eustace organizes a team of former villains into a group in order to kill Courage, ranging from recurring (arguably) nemesis Katz to the giant foot fungus, apparently ignoring/forgetting that they've endangered his own life before. They then proceed to brutalize Courage in a game of Dodgeball before he buries them in an earthquake caused by his own ability to scream.
* ''WesternAnimation/TransformersAnimated'' has a slew of B-list villains, and in one episode they come together to form the Society of Ultimate Villainy, to try and not get beaten up for a change. Hilarity ensues. [[spoiler:Even all together, they ''still'' get upstaged by a Decepticon]].
* ''WesternAnimation/EarthwormJim'' faced a team composed of all the major villains from his cartoon series. The stake? An egg-beater! No, a normal egg-beater, like the kind you have in your kitchen. Don't question the humor!
* An episode of ''WesternAnimation/SpongebobSquarepants'' features a coalition of The Dirty Bubble, Manray, and the recently-turned-evil Barnacle Boy ([[InsistentTerminology "That's Barnacle Man!"]]), calling themselves "Every Villain Is Lemons" (E.V.I.L.). This being ''[=SpongeBob=]'', they accomplish about as much as you'd expect.
* Apex tried to make one in an episode of ''WesternAnimation/SushiPack'' (partly as ThePlan), but due to the villains' lack of respect for each other, they barely got past the planning stages.
* Used in the ''WesternAnimation/LoonaticsUnleashed'' 1st SeasonFinale where four of the season's villains were gathered by [[BigBad Optimatus]].
* ''WesternAnimation/GodzillaTheSeries'' "Monster Wars" episodes had a MonsterOfTheWeek version of this, complete with [[spoiler:a resurrected Zilla, the original American Godzilla, as "Cyber-zilla"]].
* ''WesternAnimation/TheFairlyOddParents'':
** The Crimson Chin webisodes had "The Body of Evil".
** In "Escape from Unwish Island", Timmy's vengeful no-longer-imaginary friend Gary assembles all of Timmy's 'most violent Timmy hating wishes' that Timmy had unwished (as well as a Sphinx that he didn't) to get payback on Timmy for 'abandoning' them. Though they manage to win, Timmy works things out with them.
** In "[[SuperheroEpisode The Big Superhero Wish]]", Timmy makes the world like a comicbook, resulting in superheroes and villains. Taking advantage, the Nega Chin (the Crimson Chin's alternate reality evil self) forms a supervillain group out of the now superpowered Crocker, Vicky, and Francis, complete with a swamp-based 'hall of evil'. While they manage to win and take over the world, they're ultimately defeated by [[spoiler:Timmy and his powerless friends.]]
* In ''WesternAnimation/JohnnyTest'', five of Johnny's past foes form the 'Johnny Stopping Evil Force Five' to take their revenge, complete with a 'swamp lair'. Similar to their counterparts, they actually manage to hold together and reappear in several future episodes.
* LAMOS, [[FunWithAcronyms (League Aiming to Menace and Overthrow Spies)]], for the fourth season of ''WesternAnimation/TotallySpies''.
* ''WesternAnimation/TheBatman's'' done this at least twice: "Team Penguin" in the episode of the same name, and briefly in "The Batman/Superman Story, Part One". However, the latter is sort of subverted as it may be members of Bats's RoguesGallery teaming up, [[spoiler:but they were assembled to fight against ''Superman''.]]
* The ''WesternAnimation/SpiderMan1967'' animated series in one of the last episodes had three foes who had each appeared in two episodes, Electro, Green Goblin, and the Vulture, being broken out of jail by exclusive-show villain who had already appeared, the Invisible Scientist Dr. Noah Boddy. Spider-Man tricks them into fighting each other with a crash course in ventriloquism, then webs up Noah Boddy.
* The 1990s WesternAnimation/{{Spider-Man|TheAnimatedSeries}} animated series had the Sinister Six, though they were called the Insidious Six because of worries over using "sinister" on a kids show.
* The ''WesternAnimation/HouseOfMouse'' video special ''Mickey's House of Villains''.
* ''WesternAnimation/SouthPark''
** The 200th episode did this with Creator/TomCruise gathering celebrities that the show had made fun of, like Rob Reiner, Creator/ParisHilton, Creator/GeorgeLucas, Creator/MelGibson, etc. Trey Parker and Matt Stone even used the term "Legion Of Doom" when referring to this episode in an interview.
** The episode "Krazy Kripples" had Creator/ChristopherReeve create a Legion of Doom consisting of various DC and Marvel villains as well as SaddamHussein, OsamaBinLaden, [[HarmlessVillain Professor Chaos]], and [[HypercompetentSidekick General Disarray]].
* ''WesternAnimation/TheTick'' spoofs this in "The Tick vs. Arthur's Bank Account" with a villain team consisting of villains The Terror, The Human Ton and Handy, The Man-Eating Cow, Joseph Stalin, and the alien Tuun-La.
* ''WesternAnimation/SWATKats'' episode "Katastrophe" begins with a chance meeting between DiabolicalMastermind Dark Kat and MadScientist Dr. Viper. They recruit {{Killer Robot}}s the Metallikats to create an "Alliance of Evil" with only one goal: "Destroy the SWAT Kats!"
* ''WesternAnimation/CodenameKidsNextDoor''
** The very first time it happened in was in "Operation: M.O.V.I.E.", where Numbah Four tries to get into an R-rated movie, only to find that it's a very large gathering of the [=KND=]'s RoguesGallery, summoned by Mr. Boss.
** A larger scale version happened in ''WesternAnimation/OperationZERO'', where Father (and later Grandfather) uses every possible villain against the KND. It is even stated early on that the KND had never faced such a coordinated attack from their adult enemies before.
** Minor example in "Operation: F.L.U.S.H.", where Mr. Boss (again) gathers a FiveBadBand version of this, only for the [[HarmlessVillain Toiletnator]], rejected from the group, to defeat them on his own, since he mistook ''them'' for the KND!
** Another FiveBadBand would be in "Operation: M.I.S.S.I.O.N.", only it's ''Numbuh Four'' who assembles four incarcerated villains... for a bowling match against his father.
* Mirroring the comics it is based off of, ''WesternAnimation/AvengersEarthsMightiestHeroes'' has the Enchantress gathering up various villains to form the Masters of Evil. And then she gives the reigns to Baron Zemo, for some reason.
** "Zemo is but a toy. To be discarded when I tire of him."
* ''WesternAnimation/AvengersAssemble'' features the above-mentioned Cabal from ''DarkReign'' as the principal antagonists. RedSkull even explicitly states that he formed them as the villainous equivalent of the Avengers.
* The Knights of Vengeance from ''WesternAnimation/{{WITCH}}'' could be seen as one, as it was a gathering of various Phobos cronies united by Nerissa.
* The Injustice League and the Light from ''WesternAnimation/YoungJustice''. As an [[MythologyGag Easter Egg]], the Injustice League's hideout is an homage to the Legion of Doom's lair from ''Superfriends''.
* ''WesternAnimation/FamilyGuy'' mentions the Legion of Doom by name, when during Lois's bid for mayor, she claims they've teamed up with [[AdolfHitler Hitler]] to assassinate {{Jesus}}. Cut to the Legion, with Solomon Grundy admitting he "dropped the ball on this one."
* ''WesternAnimation/XiaolinShowdown'''s series finale, after getting its own plotline resolved, ended with our heroes facing a Legion composed of ''every single villain in the series''.
** The second season finale featured a smaller Legion formed by Jack Spicer. They had the heroes on the ropes for a while until [[BigBad Chase Young]] stepped in and went EvilerThanThou on them.
* ''WesternAnimation/TheMask'' episode "Convention of Evil", where most of the RoguesGallery attend a therapy session hosted by recurring character, psychologist Dr. Neumann. [[spoiler:The climax of the episode reveals that The Mask is in the meeting, disguised as Neumann himself.]]
* ''WesternAnimation/BatmanTheBraveAndTheBold''
** The Legion of Doom is featured in the episode "Triumverate of Terror!" The episode sees SelfDemonstrating/TheJoker joining forces with SelfDemonstrating/LexLuthor and the Cheetah to finally do away with Batman, Franchise/{{Superman}}, and Franchise/WonderWoman once and for all.
** The ColdOpening of that episode was a baseball game between the Justice League International and the Legion of Doom, with Joker, Luthor and Cheetah united with Weather Wizard, Clock King, Chronos, Felix Faust, and Amazo.
** "Night of the Batmen!" features an instance of a number of Batman's foes teaming up to take advantage of Gotham City while the Dark Knight is in traction.
* ''WesternAnimation/GeneratorRex'' episode "Enemies Mine".
* ''WesternAnimation/TheSpectacularSpiderman'' uses the Sinister Six twice. The first time has Docter Octopus, Electro, Sandman, Rhino, Shocker, and Vulture. The second team up trades Doc Ock and Shocker for Mysterio and Kraven.
* In ''WesternAnimation/MyLifeAsATeenageRobot'' episode 'Legion of Evil', the titular Legion ''is'' made up of Jenny's enemies. The twist is that its membership consists of her least-threatening enemies; The Hammer Bros, Lancer, Mudslinger, and led by Dr. Wakeman's deranged lab rat Vladimir. Jenny was not impressed.
-->'''Jenny:''' Your name is Mr. Scruffles, your Legion is a bunch of B-list villains, and your secret lair smells like fish.
* In ''WesternAnimation/RegularShow'', the episode "Exit 9B" has a Legion of Doom formed from the bad guys that got killed over the past 3 seasons, [[spoiler:all led by the son of Garrett Bobby Ferguson.]]
* ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' had the League of Villains.
* In ''WesternAnimation/ActionMan'', Dr. X runs a villainous team to further his schemes. In fact, it's ''literally called'' "The Council Of Doom".
* ''WesternAnimation/EvilConCarne'': Hector once decided to unite all villains and form the "League of Destruction". The villains argued among themselves about who'd be the leader. By the time TheHero arrived at the Headquarters to stop them, the League of Destruction had lived up to the name by destroying itself.
* In [[DeconstructiveParody true fashion for the series]], VentureBros has the "Guild of Calamitous Intent," which functions more as a trade guild for organized supervillainy, fitting that the "professional" villains are more PunchClockVillain, who do evil as their day to day and not really out of a will to wreak havoc. The villains outside the guild are the ones you really want to fear, as they don't play by "the rules." The series also brings together "The Revenge Society", including rogue villains such as Baron Underbheit, Phantom Limb, [[spoiler:Professor Richard Impossible]], and Fat Chance, who play this trope straight.
* The end of the season 6 opener of AdventureTime, "Escape from the Citadel," saw an impromptu team-up of escaped Cosmic Criminals coming under the leadership of [[spoiler:Finn's dad, Martin]] to facilitate their escape from the Citadel's dimension.
* Spoofed briefly in the season 15 episode of TheSimpsons "Fraudcast News," where Mr. Burns tells Smithers to "Assemble the League of Evil", a seemingly multi-ethnic team of villains (a samurai warlord, a Nazi SS officer, and an Arab Sheikh, along with a cowboy and a scientist). They were only identifiable by their clothing, as Burns had kept them stored away in a compartment in his office, and they had long since suffocated and died. As Mr. Smithers observed, "even monsters need to breathe."
