History EnemyMine / MarvelUniverse

** The Autobots and Decepticons were forced to team up ''again'' against the Cybertronian Empire, a faction of hyperevolved Decepticons who had abandoned Cybertron eons ago to create a star-spanning empire of their own. They consider the Autobots and the original Decepticons to be disgusting savages, and eventually returned to destroy their "lesser" brethren.

* ''ComicBook/SecretInvasion'': [[spoiler: the villain mastermind ComicBook/TheHood sends his forces into battle to save the Earth from the Skrulls]]. He has his own reasons for this: [[spoiler:it helps ComicBook/NormanOsborn in his ploy to take over SHIELD and instigate the Comicbook/DarkReign]]. (It's also implied that [[spoiler:The Hood had no idea of Osborn's plan, until he called together the Cabal for the first time. The Hood would have let the assembled forces fight the Skrulls, if not for the simple fact that if the Skrulls destroy the Earth, ''they destroy his business''.]])

* Caleb Hammer and Gunhawk, both of whom were hunting Kid Colt, temporarily join forces with him to defend the town of Wonderment in ''ComicBook/BlazeOfGlory''.

** One story-arc has Cap teaming up with the ''Red Skull'' of all people in order to stop a resurrected Hitler from taking control of the [[AppliedPhlebotinum Cosmic Cube]]. Incidentally, this would lead Cap to [[NoGoodDeedGoesUnpunished being briefly exiled from the United States]], since the U.S. government assumed he had turned his back on America by aligning with the Skull.

* The ComicBook/{{Daken}} and ComicBook/{{X 23}} crossover involved this. Daken was initially working with Malcolm Colcord, while playing all the other parties against one another in pursuit of his own goals. However once Colcord's intent to recreate Weapon X is revealed, Daken and Laura throw in together to bring him down. Unlike Daken's relationship with their [[ComicBook/{{Wolverine}} father]], the team-up results in them becoming FriendlyEnemies when they [[NotSoDIfferentRemark realize they're not so different]].
* In ''ComicBook/DoctorDoom'', Doom and Kang cooperate briefly. They insult each other constantly, but respect each other's intent to kill the other at some point.

** [[spoiler:After the death of the Human Torch]], ComicBook/DoctorDoom and Reed Richards have ''very'' reluctantly agreed to work together in the Future Foundation. This arrangement was brokered by Reed's genius daughter Valeria who convinced Reed that the FF needed someone as ruthlessly pragmatic as Doom if they were going to save the world. She got Doom on board by [[spoiler:promising to help undo the brain damage the Intelligensia inflicted on him in ''ComicBook/FallOfTheHulks'']].

** One ''What If?'' comic had Wolverine, Spider-Man, Hulk and Ghost Rider take up the mantle when the original FF were killed. When a villain nearly kills them too, Doom shows up and saves them, declaring that no one, save Doom, may defeat the Fantastic Four... Apparently including their replacements.

* Circumstances have forced [[ComicBook/TheMightyThor Thor]] to team up with members of his RoguesGallery, including [[MagnificentBastard Loki]], [[MoreExpendableThanYou the Executioner]], and [[DatingCatwoman the Enchantress]].

* In Marvel's ''ComicBook/SecretInvasion'' mega-event, [[spoiler: the villain mastermind ComicBook/TheHood sends his forces into battle to save the Earth from the Skrulls]]. He has his own reasons for this: [[spoiler:it helps ComicBook/NormanOsborn in his ploy to take over SHIELD and instigate the Comicbook/DarkReign]]. (It's also implied that [[spoiler:The Hood had no idea of Osborn's plan, until he called together the Cabal for the first time. The Hood would have let the assembled forces fight the Skrulls, if not for the simple fact that if the Skrulls destroy the Earth, ''they destroy his business''.]])

* ComicBook/SpiderWoman called a truce with several former enemies to escape the clutches of the Locksmith in the 50th issue of her series, and even invited a few of them to her apartment later! (Unfortunately, said party was interrupted [[HalfwayPlotSwitch by the darker threat of the story.)]]

** When Nimrod the Super Sentinel started attacking everybody, the X-Men and the Hellfire Club had to work together to defeat him.

* Franchise/SpiderMan examples.

** In the one shot comic ''Spider-Man Dead Man's Hand'', Spidey and his old enemy the Tinkerer cooperated for mutual benefit after the third Carrion infected New Yorkers with a disease that made them zombie-like minions. (The Tinker was working on a teleportation device for the Enclave that Spidey needed to get to Wungadore quickly, as he knew the High Evolutionary might have inside information on the plague, and the Tinkerer was willing to help, seeing as his son was one of the victims of said plague.)

** In one of the most memorable stories of ''ComicBook/Inferno1988'' that didn't involve the [[ComicBook/XMen mutant teams]] in the main storyline, Spidey fought alongside J. Jonah Jameson to defend the ''Daily Bugle'' against the invading demon horde. It was little wonder that the writers named the story [[ExcitedShowTitle "When the Bugle Blows!"]]

** Particularly in the [[WesternAnimation/XMen 90s cartoon]], most notably in a season-long storyline in which he and Professor Xavier are stranded together in the [[LostWorld Savage Land]].

* Examples from the Marvel ''[[ComicBook/TheTransformers Transformers]]'' comic:

* In ''ComicBook/DoctorDoom2019'', Doom and Kang cooperate briefly. They insult each other constantly, but respect each other's intent to kill the other at some point.

** ComicBook/{{Venom}} and ComicBook/{{Carnage}} hate each other far more than they hate Spider-Man. Any time Carnage pops up, Venom will call a truce with Spider-Man to go whale on Carnage. This most famously occurred in the storyline ComicBook/MaximumCarnage, which was adapted into a Sega Genesis and Super Nintendo game. Also, In the oddly-named "Venom vs Carnage" comic, after Carnage produces a new symbiote, he and Venom decide that, in the end, they hate the ''new'' symbiote even more than they hate each other (it's implied in Carnage's case that this is part of symbiote biology). The result? Their only teamup. Venom calls it "Temporary. VERY temporary."
