The opposite of Locked in a Room: the ensemble of diverse characters starts to argue and turn against each other during intense situations. E.g. being boarded up in a house/building/store when there are rampaging viruses / zombies / aliens / vampires / werewolves or what have you looming outside (or inside) trying to get to you. Which leads to paranoia, frustration, and disagreement among the group when it comes to fixing the dilemma. Patience starts to run short, the ensemble is starting to get on each other's nerves, and things quickly get out of hand and possibly implode.
When this occurs against something threatening to wipe out humanity as a whole (such as the ever-popular Zombie Apocalypse), this usually leads to An Aesop for the survivors (or the audience) about how we need to look beyond our differences and focus on the big picture, or a scathing indictment of humanity's self-destructiveness and how we can sometimes be even worse than the monsters we're fighting. This trope is also a good way to showcase the darker side of characters under stressful situations who are otherwise good people. This also can be caused by clashing egos, but mostly it's due to conflicting personalities.
This trope is named for a famous Biblical quote that Lincoln later borrowed about how "a house divided against itself cannot stand," though it is also referred to in writing circles as "Scorpions in a Box" (not to be confused with Rats in a Box, which is when this trope is invoked for the purposes of Perp Sweating).
This is frequently combined with an Ontological Mystery.
Subtrope of Divided We Fall. May be caused by an Artifact of Attraction or other Apple of Discord. Compare Gold Fever (greed may cause infighting) or No Honor Among Thieves (lack of loyalty may sink villains' plan because they can't work together). When this erupts into a full-scale war, particularly within a country, you have a Civil War.
Occasionally, a villain will try to set this up deliberately. This rarely works, at least not over the long term (though it can and often does work splendidly over the short term). See also: We ARE Struggling Together making this Truth in Television... unfortunately.
Typical character types that are found in this trope are:
- Action Girl, who may resent the Damsel characters listed below.
- Agent Mulder
- Agent Scully
- Bald Black Leader Guy
- Crazy Survivalist, who on occasion fights with both the Jerkass and the Marty Stu.
- Damsel in Distress
- Damsel Scrappy
- Jerkass... obviously.
- Marty Stu, who's always at war with the Jerkass.
- Similarly, an Ideal Hero.
- Depending on how cynical the writers are, these characters are sometimes the first ones to bite the dust.
- Similarly, an Ideal Hero.
- The Millstone
- Straw Nihilist
- Ignored Expert, Only Sane Man and Cassandra Truth
- The Load
- Psycho Party Member
- Token Black Friend (or just the token black)
- Token Evil Teammate/Token Good Teammate
- Zombie Infectee, who's sometimes the main cause of the division.
- Assassination Classroom: After learning about Koro-sensei's past, the class gets divided into two factions; those who want to save Koro-sensei's life, and those who want to continue killing him, with Nagisa and Karma leading the respective factions. Koro-sensei declares that it should be settled with a paintball game to prevent this trope from getting too far.
- Baccano!: The alchemists aboard the Advenna Avis were already divided in conflict before they received their elixir of life. Immortality should've resolved most of their disputes and rendered the rest futile to continue. But the gifting demon left an escape clause in case they tired of eternal life; they could absorb each other to take all their knowledge and experience. They quickly figured how this might be used against each other.
- Happens to the girls holed up in the lighthouse in the Battle Royale manga.
- And they all wind up dead, especially the instigator. Oh so much.
- In Gate, it seems that the Empire isn't in complete control of their lands, as seen in episode 2 when the Emperor orders his allied nations to get slaughtered by the new enemy forces occupying their gate. He later orders the surrounding regions to undergo a Salt the Earth policy, officially to deny the JSDF from obtaining local resources. But secretly it's meant to further quell any rebellious mood against the Empire.
- Infinite Ryvius. After the adults die, it takes all of two episodes for the children to start turning on one another. The vicious infighting continues even in the middle of battles.
- The Lost Village: As early as Episode 2, the 30 people that get to the village together start the infighting and looking for people to blame about the strange occurrences. About halfway through the show, things get violent enough to warrant a witch hunt against Masaki some of which want to kill her, some want to save her and some are trying to figure out what the hell is going on.
- In Naruto, there's a hardlined military faction called Root that works against the members of Konoha that follow the teachings of the Third Hokage, which includes, among others, the main character and the Fifth Hokage. There are also other factions in the Land of Fire who want the Fifth gone. None of these groups particularly liked the Third Hokage, either.
- In the RS arc of Pokémon Adventures, the Gym leaders realize that there's a terrorist group out there planning to screw over Hoenn. Since Aqua and Magma work against each other, the Gym Leaders argue about which group are the real bad guys, not realizing that though the two teams have opposing goals, both groups are terrorists. The Gym Leaders probably would have duked it out between themselves if not for the fact that Groudon and Kyogre start destroying the region. Made worse by the fact that Tate and Liza weren't there due to their duty to guard the Red and Blue Orbs, and Norman knew better and refused to take sides. Shame Sapphire wasn't at this particular meeting, or she could have vouched against them both, being a witness to the heinous deeds of both groups.
- Schwarzesmarken: This is practically the theme of the entire series. Taking place in an alternate timeline where Asia acquired an army of alien bioweapons (with no context as to whether or not Asia survived), the armies of East and West Germany are still at civil war with each other by the division made from their factions, and are willing to greatly decrease humanity's chances of survival (and even their own) if it means that they can send their rivals' entire armies into a meat grinder of Eldritch Aliens.
- In Sword Art Online, the party that Diabel attempted to put together in Episode 2 nearly falls apart due to his friend Kibaou being very mistrustful of beta testers. After they defeat the first floor boss, the hard-earned celebration is cut short by Kibaou, who accuses Kirito of indirectly causing Diabel's death and again calls for a witch hunt of beta testers. Realizing the rift that Kibaou was causing, Kirito attempts to have them channel their hatred towards him instead and acts as the Token Evil Teammate so as to not have the players start fighting amongst themselves.
- World Trigger: The story's central organization Border is split into at least 3 factions.
Kido's faction want the destruction of all neighbors.
Shinoda's faction wants to protect the town and people only, but will protect any neighbor in need just as much.
Rindō's faction wants to work with the good neighbors.
- Used in a strip in Doctor Who Magazine in which a group of minor villains that the Doctor has previously defeated gather together in a deserted space-station to plan a final attack that will finish him once and for all. One of them dies horribly, and as the others begin dying one by one afterward, it seems (to them, anyway) as if the Doctor has infiltrated their midst in disguise and is picking them off one by one. Finally, the last couple paranoid that either one of them could be the Doctor in disguise kill each other... and at that point, the Doctor arrives, not recognising any of them. Turns out the first death was just an accident with a faulty machine and the other deaths were just everyone picking each other off out of sheer paranoia.
- The Pocket God story arc "A Tale of Two Pygmies" revolves around this. Klik doesn't like how Ooga treats the tribe like a joke and is jealous at him for meeting the gods. When their hut burns down, he accuses Ooga of doing it and exiles him. However, Nooby and Booga go with Ooga; splitting the tribe of six into two tribes of three. When their sacred Gem of Life is missing, Klik accuses Ooga's tribe of stealing it and the tribes go to war. Turns out the culprit was a female pygmy named Sun, who manipulated the tribe into fighting amongst each other so she can steal their Gem of Life.
- This was pretty much the plot of the "Home Schooling" arc of Runaways. Victor Mancha inadvertently causes a drone to crash into the Runaways' house, resulting in Klara and Old Lace getting buried beneath rubble. The rubble gets sorted out relatively quickly, but Old Lace dies and Klara loses control of her powers, burying the house in vines. The team then becomes divided over how to deal with the vines, with Chase and Victor preferring to force Klara to retract them while Karolina, Nico and Molly prefer to wait until she's calmed down enough to retract them of her own free will (eventually, Nico uses a magic spell that tranquilizes Klara, but this angers Molly, who considers forcing someone to sleep against their will to be abusive.) Further complications arise when a paramilitary unit arrives to investigate the attack, causing the Runaways to flee the house while Chase abandons the team. Apparently, the arc was supposed to end with them being reunited by a suddenly-revived Gert Yorkes, but the series was cancelled halfway through the arc...
- The entire point of Schism was to break up the X-Men into those siding with Wolverine and those siding with Cyclops.
- So far the group in The Walking Dead comic manages to avoid this...for the most part.
- The core members have learned to trust each other over the constant fear that the other people aren't making the best decisions. EVERY time someone new comes into the fold, the tension surfaces. Time, and sometimes a death or two, will put things back to 'normal'.
- Wonder Woman (1942): In "Who Killed Col. South?" all the cousins are antagonistic and cruel to each other even though they know there's a murderer in the house, save for the twin brothers. In the end it turns out the twins have actually been reduced to one as the killer offed his brother and has been using "caring for his brother" to hide his actions.
- Rosario Vampire: Brightest Darkness Act III: Throughout the first few chapters, the ghoul inside Tsukune causes a schism within Tsukune's posse, with some (Moka, Kurumu, and Rason, for example) trusting Tsukune to keep the ghoul contained with the Holy Lock and others (Dark, Mizore, and Felucia, for example) firmly convinced that the ghoul is too dangerous. They all get over it pretty quickly, however.
- A New World: Weakened as the Gensokyo forces might be after centuries of isolation, had they the political will to do so, if pooled together they could deliver a lethal Zerg Rush / Curb-Stomp Battle to the invading Lunarians. However, to Kanako's ire, the two strongest armies (the oni and the tengu) are staying out, the oni because they don't see it as their problem, and the tengu because of potential succession issues, and the most technologically advanced, the kappa, are too cowardly to enter the fray without the tengu. Gensokyo's remaining forces have to make do with the remaining warriors until the Lunarians seal their doom by unwittingly helping the tengu out, allowing them and the kappa to enter the battle.
- Flawed Crystals:
- This kicks off the plot of . Steven decides at literally the last minute that now is a good time to push for Thou Shalt Not Kill against the other gems, who have all agreed the diamonds need to die and whose plan will only work if they do so without hesitation. As they are about to descend into bickering, Pearl pre-empts the fallout by choosing to drop Steven from the mission; however, this leads to them being corrupted without his shield to protect them from the diamonds' attack.
- The tie-in short Dissonant Harmony reveals this was the case among the gems themselves; their plan to dupe Steven was such a poorly-coordinated mess it's a miracle they pulled it off. They kept Amethyst in the dark until it was too late for her to back out, knowing that she would also argue; they kept Bismuth in the dark about keeping Amethyst in the dark; and they appear to forget to consult Lapis Lazuli at all.
- In The LEGO Movie, the Master Builders are at a huge disadvantage thanks to Lord Business's massively more organized robot troops.
Abraham Lincoln: A house divided against itself... would be better than this! *flies away on a rocket chair*
- As the examples above and many below can showcase, it probably would be easier to count the times when this Trope doesn't happen in a Zombie Apocalypse film.
- The latter portion of 28 Days Later, where the cast are at odds with surviving military members.
- Alien is definitely a member of this trope. Although in this particular example what divides the house (most of the time) is that some of the people work for Weyland-Yutani or similar interests and wish to study the Xenomorph to make them weapons... and everybody else is expendable.
- Happens to a small group of teenagers on a plane in the film Altitude.
- Await Further Instructions follows this course as the commands from the television — assumed to be from the government — become more and more sinister. As Nick puts it near the climax — "We've done this to ourselves."
- The Beast of War is a forgotten war movie from 1988, depicting the struggle between a Soviet tank crew and their mujahadeen opponents. Not all the conflict takes place outside the tank. The commander shoots his Afghan translator, convinced he's working with the enemy, and when another soldier threatens to report the killing he's tied to a rock and booby-trapped for the mujahadeen to find.
- Body: After they think they have killed Arthur, Cali is able to persuade Holly and Mel to go along with her plan of claiming Arthur tried to rape one of them and that they killed him in self-defence (albeit reluctantly in Holly's case). However, when Arthur turns out to be Not Quite Dead, the girls' unity starts to fray rapidly. By the time Cali proposes murdering him, Holly is in open revolt and Mel is caught in the middle.
- Captain America: Civil War is about this, with great rammifications for the Marvel Cinematic Universe thanks to Helmut Zemo's actions: friendships are torn asunder and half of the Avengers are in hiding. This is the primary reason why they lose in Avengers: Infinity War: the band is brought back together far too late to be effective against Thanos, and half of all life is wiped out as a result. It isn't until Avengers: Endgame that they're properly reformed again, resulting in a victory.
- Cube. Although the eponymous Cube is filled with lethal booby traps, they only kill two of the seven characters.
- In Dead Birds, a gang holes up in an abandoned farmhouse to lay low and divide the loot. Tensions in the gang are already running high, and when inexplicable events push the outlaws deeper into paranoia, it becomes a question of whether they will kill each other before the other horrors in the house come for them.
- The Descent. Mostly between Sarah and Juno, especially after the former found out the latter took the group caving/spelunking in a dangerous uncharted cave that's filled with flesh eating subterranean mutants, in a misguided effort to reunite the group. Not to mention the fact that Juno also slept with Sarah's deceased baby daddy. Juno's Good Intentions not only contributed to her friend Sarah's breakdown . But also led her friends to their doom.
- Juno also accidentally mortally wounded one of her friends (Beth) in the cave thinking she was one of the cave dwelling monsters. And left her there to die and tried to cover it up. When Sarah comes across the injured Beth, Beth explains what happened (including info about the affair Juno had). And tells Sarah not to trust Juno, essentially putting the proverbial nail in the coffin of Sarah and Juno's friendship.. Of course karma is a bitch, as Juno sufferers the consequences (unfairly or not).
- M. Night Shyamalan's Devil takes this beyond the average person's tolerance with an elevator full of people slowly being killed off.
- The post-apocalyptic film The Divide is fueled by this trope.
- The Stephen King story and movie, The Mist. A military project codenamed 'Operation Arrowhead' has gone awry and a quaint Maine town is shrouded in mist that happens to be filled with flesh-eating monsters from another dimension. A lucky few residents are able to barricade themselves in the local supermarket. The Fundamentalist Mrs. Carmody preaches that this is all an act of God for landing people on the moon and homosexuality. Yes, really. Yet as people start getting picked off by the monsters, most of the people in the store let their fear get the better of them and start listening to Mrs. Carmody's sermons, save for a level-headed group that find themselves outcast and fearing for their lives after Mrs. Carmody has her followers sacrifice one of the townspeople to the monsters. When they decide that they would rather face the monsters then face a religious nut, Mrs. Carmody tries to stop them and utters her final words, 'Kill them all!' before she is finally put in her place with a Boom, Headshot!.
- In Night at the Museum: Battle of the Smithsonian, Larry remembers some advice the (animated) Lincoln Memorial gave him, and begins taunting the villains and playing them against each other. Ultimately, their inability to work together proves to be the ultimate reason for their defeat.
Lincoln Memorial: A house divided cannot stand.
- In Night of the Living Dead (1968), Ben and the Mr. Cooper fight over the use of the cellar. Ben believes it should just be a last option, with Mr. Cooper thinking it's their only option and threatens to close everybody else out of the cellar if they don't make up their mind. Eventually things come to a boil in both versions of the film. Unfortunately, it turns out that Cooper may have been right. In the underrated remake Ben and Cooper get into a shoot out within the besieged house over the fact that Cooper wouldn't let anyone kill his daughter.
- Lampshaded in Pirates of the Caribbean: At World's End, and referred to as "Cuttlefish in a barrel".
- A literal example (well actually an apartment complex) in the films [REC], and Quarantine. The inhabitants never fully reach this level seeing as how the infection happens so fast people rarely get the chance to argue with one another. Although they came DANGEROUSLY close to this trope during the initial panic.
- Revenge of the Virgins: As the prospecting party is picked off one by one by the Indians, relationships become more and more strained, until the final two surviving members attempt to kill each other.
- In Saw II, this happens with the victims of the Nerve Gas House game, although not between all of them at once.
- Everyone turns against Obi once they find out that he assisted Jigsaw in kidnapping most of them. Likewise, all of them except Amanda turn against Daniel when they realize that he's the son of Eric Matthews, a corrupt detective who arrested them for numerous crimes they weren't responsible for.
- Xavier gets progressively angrier with the other victims until he decides to leave them after the antidote in his game (which he had Amanda do for him) ends up locked. Once he finds out that each digit of the code to unlock the safe at the starting room is written on the back of each victim's neck (including himself), he tries to kill everyone in order to get the antidote for himself.
- Inverted with the Fatal Five's Trial in Saw V, in which Jigsaw meant for the victims to work together through the hints he gave them as a lesson for their selfishness. Too bad the victims were so determined to act the trope out straight...
- In Saw II, this happens with the victims of the Nerve Gas House game, although not between all of them at once.
- Shaun of the Dead: Shaun tries, but what divides the house is everybody else being The Millstone (Ed) or a Jerkass (such as David, though probably an example of Jerkass Has a Point in the case of Peter pointing out that going to the Winchester was a bad idea, and yet he still comes across as jumping the Moral Event Horizon when he tries to shoot Shaun's mom when she's still (barely) alive, Zombie Infectee or not).
Shaun: As Bertrand Russell once said, "The only thing that will redeem mankind is cooperation." I think we can all appreciate the relevance of that now.
- "You read that on a beer mat, didn't you?"
- Stag: Initially the ten men are agreed that they will be unanimous I'm whatever action they decide to take regarding the two dead bodies in the living room, and the live stripper they have imprisoned in the bedroom. However, as the night wears own, relationships become strained and cracks start to show in the united façade, especially as some of the plans suggested become more...'drastic'.
- Survival of the Dead. Only it's more like an island divided. The O'Flynns and the Muldoons have such a sharp family rivalry that they don't even pay attention to the zombies killing everyone around them during the final showdown at the end. And they don't let up, either. Not even when they become infected themselves. Tsk, tsk.
- In John Carpenter's version of The Thing (1982), The researchers at Outpost 31 turn on each other when they realize the alien could imitate anyone. Paranoia and intense tension build up, resulting in one of the most bone chilling endings ever made.
- The 1951 version, The Thing from Another World, centers on a conflict between the scientists and the military over how to best deal with the alien creature (which is a more conventional monster rather than a shape-shifter).
- Welcome to the Jungle is essentially Lord of the Flies with corporate executives instead of children.
- Machiavelli in Discourses on Livy believes that this is one of the reasons for a republic's strength, since it allows the right leader to come to the fore at the right time.
- In Terry Pratchett's Discworld, wizards have a weird, formalized version of this. Wizards get along about as well as a sackful of soggy cats, something apparently programmed into them at a genetic level (or at least the level that passes for genetics on the Disc). Unseen University was created to redirect that murderous energy into a strict hierarchy where a cutting note could do nearly as much damage to one's opponent as a hurled fireball, but with a much smaller risk of bystanders being turned into charcoal (or possibly haddocks). They still cheerfully murder one another with creative booby traps, but things have settled somewhat now, since the current head of the University has proven himself more or less unkillable (and he sleeps with two loaded crossbows, although he's a kind man and probably won't shoot you in both ears).
- In The Heroes of Olympus by Rick Riordan, the Greeks and Romans need to ally themselves so they can defeat Gaea. Otherwise, they are SCREWED.
- Will Navidson and his significant other Karen move into the house because they are trying to avert this trope, but the strange happenings in House of Leaves don't allow for that sort of healing.
- In the first Hunger Games novel, it's mentioned that this usually happens to the Career tributes. The Careers typically work together in the beginning of the games to set camp, protect each other and kill as many of the non-Career tributes as possible early on. However, since there can only be one survivor in the end, as soon as there are so few non-Careers left that the Careers don't really have a common enemy anymore, distrust and disapproval starts spreading among the group, until they inevitably turn on each other.
- The good guys in J. R. R. Tolkien's works are all too prone to this. The elven factions in Beleriand are one example. Another would be the mistrust between Arnor and Gondor, and the various succession crises, secession, and outright civil wars within the realms, which give Sauron opportunities to weaken and (in the case of Arnor) eventually destroy an enemy he couldn't take on all at once. It looks like the Ring-war is going the same way (Rohan occupied with internal problems, and the southern fiefs of Gondor reserving most of their manpower to defend their coastlines) until Gandalf and Aragorn shake things up.
- It happens to the orcs, too. Merry and Pippin are able to escape when Saruman's orcs fight Sauron's orcs over who gets the captives; then the Riders of Rohan wipe out the remaining orcs. Similarly, the Minas Morgul orcs fight the Barad-dûr orcs over Frodo, and all but one are killed, whereupon Sam, coming to the rescue, kills the last one.
- In the Stephen King short story "The Mist", this happens to around 80 people stuck in a supermarket. The main threat is a deeply religious woman who urges the others to make a blood sacrifice to stop the monsters outside.
- The lighthugger Nostalgia For Infinity in Revelation Space. Despite having a crew of six (seven if you're generous), almost the entire crew hate each other's guts and are willing to murder each other. The only two characters that get along are Hegazi and Volyova, or Volyova and Khouri
- Much of Tanya Huff's Smoke and Mirrors—in which a television crew gets locked in a Haunted House—consists of this trope; they don't descend to killing each other, but... not by much.
- A Song of Ice and Fire has this as a recurring theme played straight, subverted and deconstructed in many flavours, both in the backstory (the split between the Targaryens and Blackfyres is a classic example) and the main (the three-way Baratheon split couldn't play it straighter). Of course it happens depressingly often: with bells on. It's safe to say that any House or institution is at risk when they all play the Game of Thrones. No exceptions. Moving one stage further and hitting Divided We Fall occurs, too (the Freys, Karstarks, Greyjoys, and even the Lannisters face this as an increasingly likely outcome of their inner rivalries). Some manage to pull through, however battered: the rarer cases, these (the Night's Watch has a long, chequered history of falling apart at the seams, patching it as required and soldiering on kind of as a unit... to then repeat the process all over again down the line).
- Seen in Star Trek: Gemworld during a crisis, when the six races of Gemworld, and their leaders, fail to work together successfully. Barclay calls them out on it, by appealing to the Good Old Ways:
"This is not how your ancestors survived, by ignoring a problem...The inhabitants of Gemworld have gotten soft. You prefer to bicker and fix blame instead of finding a solution. I'm sorry... that's not how the Ancients would have faced this ...The question is — will you act like your ancestors? Will you do what it takes to survive? Or would you prefer to hide in this room and bicker?
- In Undead on Arrival the rival gangs that control Devon seem more concerned with killing each other than the hordes of zombies.
- The story Who Goes There? by John W. Campbell, which provided the inspiration for the movie The Thing (1982). A Face Stealer alien is thawed out, and proceeds to start killing people in an isolated Antarctic research station. Everybody is understandably paranoid and scared to death. Besides being eaten to death of course.
- The 4400 episode "No Exit" features most of the major characters being Locked in a Room... that's trying to kill them. Their bickering and political differences lead to Shawn and Meghan's deaths, and in the end Jordan and Tom need to work past their personal differences to save the others. Interestingly, the whole situation had been caused by a 4400 with the power to create a Holodeck Malfunction mass illusion in people's heads that was sick and tired of Jordan's and Tom's fighting (and him being one of the people caught in the middle) and wanted it to stop. They (especially Jordan) made it perfectly clear that once the situation was resolved they would just go back to fighting as usual.
- In the Angel episode "Spin the Bottle" when the cast were regressed to their 17-year-old versions and trapped in the hotel. They all belong to the types listed in the header: Angel (Marty Stu), Gunn (Bald Black Leader Guy), Fred (Distressed Damsel), Cordelia (Damsel Scrappy by that time), and Wesley (Jerkass).
- In Babylon 5, the alliance against the Shadows turned in against itself when it was left leaderless by Sheridan's death. Order was only restored when the Messianic Archetype returned from the dead.
- Also happens in the Buffy the Vampire Slayer episode "The Yoko Factor" when Spike turns the Scoobies against one another.
- Doctor Who:
- Game of Thrones:
- The whole realm is at war with one another over the iron throne, while a greater threat of the White Walkers with a horde of wights mobilizes in the north.
- There has always been tension within House Lannister and they manage Teeth-Clenched Teamwork throughout the war, but as the war winds down they turn on each other with the events of the Purple Wedding being the spark that sets them off against each other.
- House Baratheon has two civil wars at the same time. Robert's brothers fight their "nephews" (who they know are not real Baratheons, but claim to be), and they also fight each other.
- In the Haven episode "Real Estate", the house is a malevolent Genius Loci that uses the characters' pre-existing tensions against them, culminating in a three-way Mexican Standoff.
- Happens from time to time on Lost. Often a main character will stop the fighting and remind everyone that there are other threats to their survival without them turning on each other. Jack, Locke, and Hurley have delivered such speeches, beginning with Jack's "live together, die alone" speech in an early episode.
- The YouTube series "Origin" hits this trope head first as early as the second half of the first episode.
- In The Outer Limits (1995) episode "Abduction", an alien kidnaps five high-school students, and tells them that one must be killed. They must decide which of them it will be. And of course they're from completely different social groups. Ray, a typical jock, Danielle, the hottest girl in school, Jason, a stereotypical geek, Brianna, a devout religious girl, and Cody, a social outcast. So needless to say they don't get along. But then again it was a test. And the ensemble was picked for that very reason.
- Star Trek: Deep Space Nine: This came up in "The Ship", when Captain Sisko and crew have to take shelter in a crashed Jem'Hadar fighter while more Jem'Hadar are shelling their position. Most of the tension is between O'Brien and Worf over how to deal with a dying Red Shirt (O'Brien wants him to keep fighting for life, while Worf implies killing him to spare his suffering), though everyone gets into the act.
Sisko: I know it's hot. We're filthy, tired, and we've got ten isontons of explosives going off outside. But we will never get out of this if we don't pull it together and start to act like professionals!
- The Twilight Zone episode "The Monsters Are Due on Maple Street".
- This is an underlying theme of the first season of The Umbrella Academy. By the end of the first episode, the siblings are already accusing each other of murdering their father, and tensions only escalate from there. Ultimately, by bullying Vanya and then trying to lock her up when she comes to them asking for help with her new powers, the Hargreeves siblings end up causing the apocalypse they were trying to prevent.
- This is a big part of the collapse of the Barksdale Organization in Season 3 of The Wire. Avon Barksdale and his longtime Consigliere and Blood Brother Stringer Bell had turned the group into the most powerful drug empire in Baltimore prior to the start of the show. However, when Avon goes to jail at the end of Season 1 and when Stringer has to guide the group, he comes to believe that Avon's brutal methods of controlling the drug trade by force will no longer work, and turns the organization to more legitimate business and cooperating with other gangs. When Avon gets out of prison he disdains Stringer's goal of going legit and has a Just a Gangster attitude, and this conflict of leadership and a Mob War with new, Darker and Edgier gang that is more ruthless than Avon ever was results in the most of the organization being arrested or killed.
- Fittingly enough, this happens in 1865. Lincolns former cabinet picking sides between President Andrew Johnson and Secretary of War Edwin Stanton. Later, Congress also picks sides, largely along partisan lines, after Johnson is impeached.
- This was offered as the main reason the nWo was so successful against WCW; the WCW wrestlers were a bunch of gloryhounds with a ton of unsettled issues against each other and a desire for the spotlight, while the nWo operated like a well-oiled machine.
- This trope almost cost Ring of Honor the CZW feud when Bryan Danielson deemed eliminating his challenger in Samoa Joe more important than eliminating the invading promotion. Of course the CZW side wasn't completely on the same page either and initially wasn't a threat because it.
- A subversion of the villainous version happens in Survival of the Fittest — Burton Harris/Ken Lawson plays off the paranoia and reservations of a group of students hanging out in a cottage in order to get the entire uneasy alliance to dissolve. Burton/Ken wasn't exactly a villain though, just a dick who thought that the place was too crowded.
- Happens regularly in BattleTech. House Marik, given its realm's disputes between the provinces and federal government, is stereotyped as this, but the other four Great Houses have all had civil strife of some kind in their history, and regional lords or military generals in all states are often at odds with the national leader.
- The Clans - both collectively and within each Clan - also have this a lot. In addition to historical rivalries conflicting views on Kerensky's intentions for them led to the Crusader-Warden ideological divide, with individual Clans either supporting one vision or hosting adherents to both within their ranks.
- Then there's the Realm in Exalted, now that the Scarlet Empress has vanished. The Anathema are on the loose, new and sinister forms have emerged, one Realm outpost has been conquered by a Deathlord, the Bull of the North is on the rampage, and the most likely outcome within the Realm itself is all-out civil war over the Scarlet Throne.
- Warhammer 40,000's Imperium intentionally invokes this trope with every institution, organization and military unit mistrusting everyone else. This does leave them with a bureaucratic nightmare where military or humanitary aid for worlds may arrive a century after it was needed, but it also keeps the human race comparably safe from the danger of a high-ranking defector. This lesson was learned after two bloody civil wars, one of them tearing humanity out of its early golden age.
- This also happens to foster an environment where different parts of the military occasionally go to war with each other, however...
- Warhammer Fantasy, this happens occasionally in The Empire, when an Emperor dies or retires the Elector Counts tend to disagree who would be the next. There was once the time of the Three Emperors, where three Counts decree themselves as Emperor of the Empire that it's a miracle that the provinces didn't fall into all-out civil war over who is the rightful Emperor.
- Not uncommon in Among Us, where the presence of impostors slowly killing members of the crew makes the good guys extremely suspicious of each other. Innocents may be executed by the crew via majority vote, which directly helps the impostors accomplish their goal of killing them all.
- Darkest Dungeon 2 replaces the affliction mechanic of the first game with relationships. Should two characters form a bad relationship, they will constantly bicker and pettily try to sabotage one another. This ranges from dealing stress, preventing skills, and debuffing one another. Amusingly, sometimes one of them recovers stress when the other is attacked because they hate them that much.
- A persistant theme in the Mass Effect Trilogy, but especially the third game when the war finally comes. The Asari, Turian and Salarian Councillers prefer to board up rather than try and help Earth (who are building a weapon that could stop the Reapers), so Shepard gets around it by performing favours for their military leaders instead. By the end of the game the war has turned so sour that everyone who turned away from Shepard comes crawling back to them after their homeworlds have been sacked.
- Directly referenced in Mass Effect 2 in "A House Divided" Mission, which is Legion's Loyalty Mission. It references how the Geth software comes to a consensus before making any decisions: normally this is quick, but the Geth who worship the Reapers are causing a schism in the race.
- Mortal Kombat
- In the Story Mode of Mortal Kombat 9, the Earthrealm warriors get into arguments and outright fights between each other a lot, either through misunderstandings or because they are genuinely angry at each other. (Of course, this is done so the player can have a diverse range of opponents.)
- This happens in Mortal Kombat X too, but the bad guys are worse, the outland being in a Civil War between the factions of Mileena and Kotal Kahn. This means two Outworld factions fighting Earthrealm and each other for most of the game.
- This drives the plot of The Answer episode of Persona 3 where the main cast argue on how to use the Keys in the Abyss of Time. Yukari wants to go back in time to prevent the protagonist's death, and Mitsuru ends up supporting her. Akihiko and Ken believe that they should return to the present. Junpei (as well as Koromaru) leans more toward Akihiko's side, but believes that they should only make a decision they agree on as a group. The rest of the group is undecided. The issue is ultimately resolved by Aigis and Metis, supported by Fuuka, defeating the other three pairs, forming the combined key and deciding to confront Erebus before returning to the present.
- In Red Dead Redemption 2, by the time the gang reaches Beaver Hollow, everyone is at each other's throats. Dutch, Bill and Javier are highly mistrustful and hostile to Arthur and John in particular. Micah is quick to spread rumors that they are the traitors. Any friendly banter, festivities or general civility is gone and replaced with arguments and bitterness. Those who aren't outwardly aggressive are either spending their time crying, suffering silently or giving into whatever addictions they have.
- In Danganronpa: Trigger Happy Havoc, the villainous headmaster Monokuma informs his students that the only way to escape Despair Academy is to murder one of the others without getting caught. On top of this, he gradually introduces extra motivation, leading to more paranoia as nobody can be sure who's going to try and get out.
- This came out particularly strongly in the first arc of Umineko: When They Cry because the characters are stuck in a Closed Circle where Everyone Is a Suspect.
- This quickly sets in during Virtue's Last Reward due to the way the Nonary Game is set up. If someone opens the "9" door before everyone else can get 9 points, then no one else will be able to escape. Furthermore, if someone is betrayed and drops to 0 points, they die. And finally, it's fairly certain that one of the participants in the game is Zero, the mastermind behind the whole thing.
- The Trolls from Homestuck eventually become this, as shown by this update and the ones following it. They start off with twelve. Currently, they're down to four (five and a half if you include Aradia and Sollux), and Kanaya expresses an interest in making it three.
- Unsounded: At Litrya Shrine Quigley runs off after kidnapping the artificer who has Vienne's work, she tells Matty that Quigley is the one who sold out Vienne so Matty steals Uaid, grabs Jivi and flees, Duane is in denial and lets Aldish soldiers into the Shrine thinking they'll only go after the empty military installation and not attack any of the kids or travelers in the Shrine, Sette is trying to recruit Sara to her "gang", and then Jivi asks Matty to let him leave because he feels guilty leaving the shrine under attack. This means that of the seven main characters—who were all working together at the Shrine before Duane started pontificating and Quigley ran off—only Emil and Elka are still working together.
- One Hundred Yard Stare: Episode four sees the girls turning into this trope.
- Mahu: The "Noble Democracy" of the Polish Commonwealth makes ruling the kingdom nearly impossible, to the point where generals have to ask for favours and use their own coin to pay for the armies which will fight the kingdom's wars. This chaos and inefficiency, coupled with corruption and economic pressure, cause the revolution which will bring the first Commonwealth Republic.
- Escape the Night features a version of this every season, sometimes even twice a season. Usually before a voting ceremony takes place and after the challenge. In Season 3, almost every episode begins and ends with a conflict splitting the group apart into the 'Boy Scouts' and 'Mean Girls'. And Joey.
- The driving conflict of The Night the Animals Talked
