* In the first ''WesternAnimation/ToyStory'', Woody and Buzz are initially bitter enemies due to Woody's jealously over Andy's affection, but when the two toys end up separated from the rest of the group, they must work together in order to get back home. [[spoiler:They then become [[FireForgedFriends good friends]] for the rest of the franchise.]]

* This trope is the whole point of ''WesternAnimation/MonstersVsAliens'', though the monsters [[AntiVillain are pretty good-natured]].

* In ''WesternAnimation/{{Shrek}}'', [[spoiler:the titular ogre (and rather unconventional hero) teams up with the dragon who was guarding the DamselInDistress, whom he had to recover (normally he'd have to slay the dragon, but this time he just outwits her). Which he lives to be grateful about, as she comes to help because Donkey, who she loves, asks her to.]]
* In ''[[WesternAnimation/TheSpongebobMovieSpongeOutOfWater The SpongeBob Movie: Sponge Out of Water]]'', [=SpongeBob=] and Plankton team up to retrieve the Krabby Patty formula after its theft by someone other than the latter turns Bikini Bottom into a post-apocalyptic wasteland.

* In ''WesternAnimation/{{Shrek}}'', [[spoiler:the titular ogre (and rather unconventional hero) teams up with the [[InstantAwesomeJustAddDragons dragon]] who was guarding the DamselInDistress, whom he had to recover (normally he'd have to slay the dragon, but this time he just outwits her). Which he lives to be grateful about, as she comes to help because Donkey, who she loves, asks her to.]]

* This trope is the whole point of ''WesternAnimation/MonstersVsAliens'', though the monsters [[AntiVillain are pretty good-natured]].
* In ''WesternAnimation/TheBossBaby'', Tim agrees to help Boss Baby "just to get rid of [him]". Neither really likes each other, at least at first. Boss Baby agrees because he wants to leave just as much as Tim wants him gone so that he can get promoted.
* At the climax of ''WesternAnimation/TheLEGOBatmanMovie'', the Batfamily and the entire Batman RoguesGallery (except ComicBook/TheJoker) join forces to save Gotham City from the Army of Evil.
* The animated ''[[WesternAnimation/TheHobbit Hobbit]]'' exaggerates it for laughs. Thorin and the elf king go from charging each other spitting curses to "your people are as brothers unto mine" in less than a minute when the goblin army shows up. Only [[OnlySaneMan Bilbo]] thinks there's anything odd about this.

* In ''WesternAnimation/{{Shrek}}'', [[spoiler:the ogre teams up with the [[InstantAwesomeJustAddDragons dragon]] he was sent to slay to save the DamselInDistress from the KnightInShiningArmor, because HumansAreTheRealMonsters.]]
** Though slaying the dragon was never part of the bargain; he just had to recover the princess (normally he'd have to slay the dragon, but this time he just outwits her).
** Also, [[spoiler:she comes to help because Donkey, who she loves, asks her to.]]

* This trope is the whole point of ''WesternAnimation/MonstersVsAliens'', though the monsters [[AntiVillain are pretty good-natured]].
* In the ''WesternAnimation/{{Futurama}}'' movie "Bender's Big Score", not only is the Robot Devil providing music at [[spoiler:Leela's abortive wedding]], but they later team up with the robot mafia and evil robotic Santa to take Earth back from the scammer aliens.
* When Prince Achmed from ''WesternAnimation/TheAdventuresOfPrinceAchmed'' stumbles into the volcano home of a powerful witch, she tries to strangle him. When Achmed finally manages to tell her that he was marooned there by the evil wizard, she says "He is my greatest enemy! And we are friends!" She then helps Achmed defeat the wizard.

* The example from WildMassGuessing for ''WMG/TheXFiles'', suggesting that as soon as the aliens arrive on Earth, they'll promptly be beaten back by ''every single MonsterOfTheWeek'', who tend to favor continuing to live on their planet.
* In ''FanFic/AeonNatumEngel'', during the Herald fight, the Migou recall some of their forces so that the NEG Military, with the newly freed-up forces, can assist in defeating the Herald. Humanity doesn't return the favor.
* One issue of ''[[FanFic/UltimateSpiderWoman Ultimate Spider-Woman: Change With the Light]]'' has petty criminal Blizzard teaming up with Spider-Woman to help her protect the innocent people in danger during an invasion of New York City by an army of BrainwashedAndCrazy super villains. Taking inspiration from the ''WesternAnimation/DarkwingDuck'' episode where DW teamed up with Megavolt (see below), Blizzard points out that if New York is destroyed, there'll be nothing left for him to rob.
* ''ADarkKnightOverSinCity'' features Franchise/{{Batman}} and the [[AntiHero anti-heroes]] from SinCity teaming up together and with other criminals in order to achieve their goals.
* In ''FanFic/HogyokuExMachina'', Yoruichi is surprised when she finds out that the Vizards fought alongside Soul Society against [[BigBad Aizen]] in the [[TimeTravel original timeline]], since they have no reason to like them. [[TheSmartGuy Ishida]] suggests it was because of this trope.
* Villain example: Although [[spoiler: Brox and Co.]] and the Raleka in ''Fanfic/WithStringsAttached'' aren't exactly mortal enemies, they dislike each other considerably. [[spoiler: Brox and Co.]] are contemptuous of Ketafans in general, and the Raleka hate that the skahs want to use the sacred Vasyn for stupid purposes. However, they work together against the four because the Raleka cannot do certain things without [[spoiler: Brox's help]]. We find out later that [[spoiler: Brox and Co.]] were planning to betray the Raleka, but Paul and George inadvertently screwed this up for them.
* ''FanFic/TheImmortalGame'': In a plan born of desperation to defeat [[BigBad Titan]] during the FinalBattle, the Mane Six end up allying with [[spoiler: Discord]]. As [[spoiler: Celestia]] puts it, they know the latter will probably betray them after they're done with Titan, but they can handle that, and besides, "[[LesserOfTwoEvils better the devil you know]]".
* ''FanFic/QueenOfAllOni'': When Valmont uses the power of Kaito's mask to steal the Ninja tribe away from Jade, she and Jackie briefly (and reluctantly, in her case) team up to defeat him.
** Subverted in one of the scenes set in [[GhostInTheMachine Jade's mindscape]] -- Hero tries to form an alliance against [[SuperpoweredEvilSide The Queen]] with his apparent rival Father, but is rejected.
** In a similar subversion, the J-Team refuses to ally with [[FutureBadass Karasu]] against Drago, as they don't see any good coming from working with a Shadowkhan.
* [[CardCarryingVillain Dr. Brainstorm]] tries to {{def|iedTrope}}y this twice in ''Fanfic/CalvinAndHobbesTheSeries''. Both times, he ends up playing it straight.
* This happens in the Naruto/Justice League crossover Fanfic/ConnectingTheDots when Naruto and Sasuke team up against a REALLY big threat.
* ''FanFic/ABriefHistoryOfEquestria'': When Wind Whistler led a coup against [[TheCaligula Commander Sullamander]], she recruited help from Star-Swirl the Bearded and the few unicorns loyal to him. True, Star-Swirl was open-minded and friendly with the other tribes, but that's still members of one nation asking help from members of a rival nation to overthrow their leader.
* ''FanFic/EnemyOfMyEnemy'': ExactlyWhatItSaysOnTheTin, and awesome. Take a UNSC colony and add one shipload of Elites being chased by one carrier full of Brutes..
