Legion of Doom



""Meanwhile, at the Legion of Doom...""

Plot of an episode or Story Arc, wherein one or more villainous characters—usually made up of some combination of past one-shots, members of the Rogues Gallery, 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. Crossovers do this a lot, using one villain from each series.

Named after the nemesis organization to the Superfriends, who actually managed to stay together, mostly due to relentless use of a Deus Ex Machina Reset Button to escape in the last scene, usually because their Hall of Doom can fly or burrow anywhere.

Likely to be a Big Bad Duumvirate as well. Evil Is One Big Happy Family is usually involved. For one-shot team ups that are usually on a smaller scale, see Villain Team-Up.

Anime and Manga

 * In Ranma ½ during the Moxibustion Story Arc, 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. All but one ...
 * Parodied with usual relish in Yu-Gi-Oh the Abridged Series with the episode "Marik's Evil Council Of Doom".
 * There was a Monster of the Week in the first season of Sailor Moon that did this, with predictable results.
 * Before Kamen Rider Decade's Great Shocker below, there was the Badan Empire in Kamen Rider Spirits, which revived every single Monster of the Week and Big Bad from the Kamen Rider franchise up to Kamen Rider Super-1 midway through the plot.
 * Even Naruto manages to pull this off, by way of
 * Not exactly, since  However, its played straight in-universe with  . 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 Dragon Ball GT, where the gates of HFIL break open, releasing an army of villains from both the original series and Z.

Comic Books

 * Alex Ross, a huge Superfriends fan, did a limited series called Justice, which was his Darker and Edgier version of the series. Check out his vision of the Legion.
 * Naturally, absurdly common in comic books. There was even a short-lived Marvel series, Super-Villain Team-Up.
 * Comic book example: Batman's Gangland Guardians featured an assembly of 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 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-Justice League of America 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 heelish mock surrender. The Society even had their own series.
 * Later expanded during and after Identity Crisis. 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 Flashpoint and the New 52.
 * The whole premise of the miniseries 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 Real Life political coups by politically expedient alliances.)
 * Another Batman example. In an issue of a Golden Age Batman comic The Joker 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 them 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 Justice Society of America 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 X-Men have an annoying habit of grouping most X-Villains as members of the Brotherhood of (Evil) Mutants with 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 X-Men team- Mister Sinister's Marauders, who are a lot less picky about who to team up with. Though he 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 Genre Savvy 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 Neutral Evil rather than Chaotic Evil), they teamed up during The Silver Age of Comic Books to take on Bats and Superman, by robbing Fort Knox with nigh-invulnerable robots. 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 Evil Counterpart to the Legion of Super-Heroes, the Legion of Supervillains, especially the latest incarnation, led by Superboy-Prime, wherein the roster consists of almost all of the villains the Legion ever faced.
 * The Ur Example is the Monster Society Of Evil, who fought 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.
 * Recently, in Ghost Riders: 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 (Legacy Character 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 (No, not that one, but rather a maniac with a pitchfork who commands crows).
 * Marvel has several: The Masters of Evil, the Sinister Six, Hood's Gang, 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 History's Crime Wave.
 * 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.
 * Thor in early stories had Mr Hyde and Cobra teamed up to deal with. Later they were given help by Loki. They continued causing trouble for other heroes until Cobra split up from Hyde, causing Hyde to want revenge.
 * A particularly enjoyable miniseries example came from Marvel a few years ago: MODOK's 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,
 * The Rogues started out as a Villain Team-Up in The Silver Age of Comic Books, 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.
 * Fall of the Hulks gave us the Inteligencia, a group of Marvel's smartest villains. Unlike most examples, they've managed to not fall to bickering and work torwards a common goal.
 * There was the Superman Revenge Squad, which fell apart because they couldn't cooperate.
 * An early Superman story had the Terrible Trio, made up of Lex Luthor, the Toyman, and the Prankster.
 * In Top Ten, 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 the Dark Reign thing, Norman Osborn set up a "Cabal" consisting of himself, Emma Frost, Namor, Dr. Doom, The Hood, and Loki. It... uh... worked out about as well as for Osborn as everything else did in that saga.
 * But there was also a Dark Avengers, with villains impersonating heroes.
 * Image's Guarding the Globe series introduced us to the Order, a select group of minor recurring 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
 * In All Fall Down, the Order of Despots is this to the Pantheon.

Film

 * The 1966 live-action Batman: The Movie, featuring the Joker, the Penguin, the Riddler, and Catwoman ("United Underworld") in a cheesy  submarine. They even went through the trouble of making a logo.
 * An octopus strangling a globe? What Do You Mean It's Not Awesome??
 * 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 Batman Forever and Mr. Freeze allies with Poison Ivy and Bane in Batman and Robin. More or less subverted in Batman Returns 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 Shrek 3 with fairy tale villains.
 * All of the System Lords band together under  in Stargate: Continuum. This is particularly noteworthy, considering that they usually fought most of the time during the series, which was their main weakness.
 * Scooby Doo Monsters Unleashed film, reviving many of the Monsters of the Week that Mystery Inc. has unmasked in the past. However, this time, all of them are real.
 * In Night at the Museum 2, Kahmunra recruits Napoleon, Ivan the Terrible and Al Capone as his evil team. Darth Vader and Oscar the Grouch also try to join it.

Literature

 * Anno Dracula features a Legion of Doom comprising Fu Manchu, Professor Moriarty, Colonel Moran, Raffles, The Invisible Man, Macheath and Bill Sikes. In a twist, they join forces with the heroes to stop the Silver Knife, because Even Evil Has Standards ... or at least, good business practices.
 * Harry Dresden of the Dresden Files names the shadowy force the Black Council so as to not call it this trope. He also calls it a phantom menace at one time, but asks forgiveness for the phrasing.

Live Action TV

 * Smallville did this at least once.
 * The final episode of Team Knight Rider, aptly titled "Legion of Doom", featured all the villains from the series teaming up under the command of the series' Big Bad.
 * Doctor Who has toyed with doing this on several occasions, but it never quite works out. In "The Five Doctors", many of the Doctor's worst foes are brought together to finish him off - but they are merely pawns of The Man Behind the Curtain, and apart from the Master and the Cybermen don't even interact. "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 (Yellow Peril and Diabolical Mastermind 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 "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 "The Pandorica Opens", in which a couple dozen races show up, apparently to squabble over whatever is imprisoned in the eponymous device, Seen on screen are the Daleks, the Cybermen, the Sontarans, the Silurians, Nestene duplicates and the Judoon, and many more get name checks or cameos in crowd shots.
 * Done at least twice in Power Rangers. Once with In Space with Dark Specter's United Alliance Of Evil (rounding up six seasons' worth of villains), and again in the Operation Overdrive 15th anniversary "Once A Ranger" 2-parter, with the never-seen-before son of Rita Repulsa and Lord Zedd uniting the season's Big Bad Ensemble.
 * Kamen Rider Decade introduces a particularly large version in the form of Great Shocker, which is an alliance of every single evil organization from Kamen Rider's 30-plus-year history united under a single banner and dedicated to conquering the multiverse and destroying all the Kamen Riders. In Final Chapter,  In Kamen Rider X Super Sentai: Super Hero Taisen, Great Shocker has been rebuilt with its leader back into the seat and Doctor G as his 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 Kaizoku Sentai Gokaiger section below for their side of the story.
 * In a smaller scale, the final episode sees Apollo Geist reviving some of the Monsters of the Week that Tsukasa and company dealt with while travelling through the AR worlds.
 * The 40th anniversary movie Let's Go Kamen Rider has Shocker persisting into the 21st century thanks to Ankh sneaking into Den-O's time-traveling train for want of medals; its membership in 2011 includes villains from all over the franchise like General Jark and Ryubee Sonozaki/Terror Dopant.
 * The "On the Next..." preview for episode 25 of Kamen Rider Fourze 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.
 * In the Reunion Show with Kamen Rider OOO, Foundation X uses the research its agents gathered to build an army consisting of various Monsters of the Week as well as mooks from the three series involved (Fourze, OOO and W), alongside monsters of the Big Bad'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.
 * The final episodes of Kamen Rider Den-O features the Big Bad amassing an enormous army of the series' Monster of the Week in order to outnumber the heroes (two Riders and 5/6 Imagin) and accomplish his plans. This army would later be ressurected in the third movie, Final Countdown, under the movie's Big Bad.
 * Not wanting to be left out, there is the 30th anniversary celebration Go Go Sentai Boukenger vs. Super Sentai, where High priest Gajah makes an alliance with the movie's Big Bad, Chronos, who in turn revives Tsue Tsue, Meemy and, in the very last minute, Furabijo.
 * The movies for the 35th anniversary series do something similar - Kaizoku Sentai Gokaiger is already a Decade-style-celebration, but its villains are the completely original Zangyack Empire. However, the first movie involves said empire making an alliance with the Black Cross King, a revived rubber suit form of the Black Cross Fuhrer from Himitsu Sentai Goranger, who in turn revives Brajira and a number of villains from Mahou Sentai Magiranger and Engine Sentai Go-onger.
 * Among the lackeys of the villain of Kaizoku Sentai Gokaiger the Movie The Flying Ghost Ship is a revived Agent Abrella, who himself leads an army of nearly every Mook that has existed in Sentai history.
 * In Kamen Rider x Super Sentai: The Great Superhero War, Zangyack has been expanded into "Great Zangyack" by the hands of their new emeperor, ; its membership includes a number of high-level villains from all over the Super Sentai franchise like Doukoku and Bio Hunter Silva.
 * 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 inversion—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 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 leading them they quickly betray him for a more fitting leader.
 * Sue's self-described Leg - uh, League of Doom in Glee, if you replace "supervillain" with "returning character with a grudge against the local show choir". She even gives them code-names, dubbing herself General Zod.

Music
"Howe and Burgoyne and Clinton, too With Prescott and Cornwallis joined, Together plot our overthrow In one infernal league combined."
 * 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.

Professional Wrestling

 * Legendary Professional Wrestling stable The Four Horsemen started out as a Legion of Doom-esque gathering of heels. More recently, Rated RKO is the teaming of two of D-Generation X's biggest rivals, and D-Generation X itself was originally formed to fight against The Hart Foundation. There is also a tag-team called the Legion of Doom, but they're not an example of this trope. And we can't let the Pro Wrestling entry go by without a mention of the nWo, can we?
 * By the time they entered the WWF the LOD might have been a tag team but in GCW they were actualy an example of this trope and included such other legends as Jake the Snake, The Spoiler, Matt Borne (AKA the first Doink), King Kong Bundy, Arn Anderson, and for perhaps the only time both of the Sheiks Iron and Original.The two remaining members were made into a tag team and were supposed to be called the Road Warriors hence why they are introduced as "Road Warrior Hawk" and "Road Warrior Animal". The two names have been used interchangeably since then.
 * In 1995 Kevin Sullivan and his “Father” The Master (King Curtis Iaukea) put together one of the most imposing heel stables of all time called the Dungeon of Doom in WCW. Originally Vader was supposed to be the center piece assisted by legendary monster Heels like Earthquake (now called The Shark) Kamala and Bruits Beefcake (now called Zodiac). Vader left soon after it was formed and the stable got a new centerpiece in the form of The Big Show (then call The Giant). Haku (then known as Meng)who is generally considered one of if not the most legitimate tough guys in wrestling also joined the group. At Halloween Havoc 95 the group really began to hit its stride with the inclusion of former world champion Lex Luger and the legendary Mangier Jimmy Hart. The stable would expand over the next several month to include such legends as the Barbarian One Man Gang, Giant Haystacks (billed as the Loch Ness Monster) Big Bossman (called Big Bubba for legal reasons) Jacqueline and Konan. While the stable may have peaked during the spring of 96 they continued to be force in WCW until they were disbanded in August 97.
 * 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 and Ze Gangsta. They fought Hulk Hogan and Randy Savage in the "Tower of Doom", a triple-decker cage. However, at the apex of his Boring Invincible Hero status, Hogan was still two much for the eight memebers of the Alliance and he and Savage soundly beat them.

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 Warhammer Fantasy Battle and Warhammer 40,000, 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.

Theatre

 * The stage play Doctor Who: 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.

Video Games

 * In the first Kingdom Hearts, the villains from various theatrical Disney movies banded together under the command of Maleficent from Sleeping Beauty. As with most of the (relatively rare) video game cases, the villains didn't turn on each other; instead, the heroes 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 Kingdom Hearts II.
 * The premise of Nicktoons Unite! is that Jimmy Neutron's nemesis Professor Calamitous steals his plans for a dimensional portal to form an "Evil Syndicate" consisting of him, Vlad Plasmius, Plankton, and 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-Boss Rush 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 Enemy Mine situation (Well, until the Snap Back). Nevertheless, both incarnations never got to infighting at all.
 * Dissidia Final Fantasy has a Legion made up of the main bosses from the first 10 Final Fantasy 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 Destroyers, Schemers, 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 Super Smash Bros. 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,, to make the Subspace Army. Bowser, Ganondorf, and Wario all end up eventually betraying the army, joining the heroes   However, Ganondorf planned on overthrowing Master Hand and becoming the army's leader long
 * Marvel Ultimate Alliance 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 King's Quest 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 Bads were part of the society...and possibly all of them were either members or allied with them. The Fan Remake of the second game and the Fan Sequel have run with the "possibly all of them" theory.
 * In Super Robot Wars 2, Bian Zoldark created the Divine Crusaders using the combined might of the Principality of Zeon, the Dinosaur Empire, and 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 Viewtiful Joe, 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.

Web Comics

 * The Axis of ... Something in 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 pulled that drama tag).
 * The Crossoverlord gathered enemies of story's main characters, creating this. At last one for each hero, two in the case of Dasien, but none for The Green Avenger (maybye because her only enemy at the point was walking alarm clock.
 * The League of Recurring Antagonists in Casey and Andy.
 * In The Order of the Stick, 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 Eight Bit Theater, four villains assembled to be the opposite number to the Warriors Of Light.
 * The Doctor Who fancomic The 10 Doctors, apparently influenced by the lack of this trope in the series (see above), goes nuts with it. The Celestial Toymaker is working for Omega. The Renegade Daleks are taking commands from the Valeyard. The Rani is assisting Davros and the Imperial Daleks, who are themselves controlling the Cybermen. The Master is using the War Chief and the 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.

Web Original

 * The Evil League of Evil in Doctor Horribles Sing Along Blog, led by Bad Horse and his terrible death whinny.

Western Animation

 * Superfriends is the Trope Namer and the Trope Codifier.
 * In the DuckTales (2017) episode GlomTales! Flintheart Glomgold tries to form a group of Psycho Rangers out of the show's already existing Rogues Gallery. When trying to match up people to mirror Scrouge's family, he left out Della Duck.
 * 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.
 * The Powerpuff Girls, episode "Meet the Beat-Alls", which was also made almost entirely of 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 provacation to get teeth - long story ) a bunch of villains including all of those from the Beat-Alls get together and beat her down.
 * Kim Possible, "A Sitch In Time" (sic), wherein the biggest villains join up in a Time Travel scheme, and get double-crossed by Drakken's sidekick Shego.
 * The last season of Teen Titans, assembled by the Brotherhood Of Evil.
 * The last season of Ben 10 with the Negative Ten.
 * Justice League 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, made 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 Superfriends, complete with
 * 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, 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 excercises and training.
 * The episode with the Justice Guild has the Injustice Guild, based on the Injustice Society.
 * Aqua Teen Hunger Force subverts this trope in the episode "The Last One", in which the Mooninites gather all the... "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, goes nowhere.
 * The enemies of Darkwing Duck join forces to become the Fearsome Five, 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 Duck Dodgers, 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.)
 * The Council of Doom was the collective name of Space Ghost's sworn enemies: Brak, Zorak, Moltar, Black Widow, Creature King and Metallus.
 * In an episode of Courage the Cowardly Dog, 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.
 * Transformers Animated has a slew of B-list villains, and in one episode they come together to form the Society of Ultimate Villany, to try and not get beaten up for a change. Hilarity ensues..
 * Earthworm Jim 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 SpongeBob SquarePants features a coalition of The Dirty Bubble, Manray, and the recently-turned-evil Barnacle Boy ("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.
 * Erm, but E.V.I.L. WINS in that episode. It's only the fact that Barnacle Boy/Man's demands are so modest that scuppers his allies' plans. "C'mon - WORLD DOMINATION!..."
 * But during the Everybody Laughs ending, Man-Ray and the Dirty Bubble are revealed to be in jail. Sure, they might have won the physical fight against the heroes, but they still make no progress at all due to Barnacle "Man"'s meager demands.
 * Apex tried to make one in an episode of Sushi Pack (partly as The Plan), but due to the villains' lack of respect for each other, they barely got past the planning stages.
 * Used in the Loonatics Unleashed 1st Season Finale where four of the season's villains were gathered by Optimatus.
