The hero is working to stop the EvilPlan of the EvilOverlord, and has, at long last, found an ally. No, wait... perhaps ally is too strong a word. This person is fighting the BigBad, just like the hero, but is doing so on their own terms with their own agenda. This agenda doesn't run contrary to the hero's, but at the same time the other person's agenda doesn't fall seamlessly in line with the hero's goals, either.

This so-called "ally" isn't overly concerned with the hero's welfare, or whether or not the hero succeeds in his mission. He or she isn't actively out to hurt the hero, it's just that they would happily betray the hero to the bad guy if it means that one of ''their'' schemes succeeded. But as long as the hero is of use to them, they'll help out when they can. They aren't necessarily malicious... they just have a mission of their own they are attending to.

Occasionally, the "ally" will actually be another villain, who, for some reason, has decided that helping the hero is beneficial to his own long-term goals. Often, this is part of a XanatosGambit; if they can use the hero to do some dangerous dirty work then why not? They either accomplish a goal or lose a potential enemy. It's win-win.

Expect the phrase "The enemy of my enemy is my friend" to be used, a sentiment that is quite often proven false in such situations.

Compare DividedWeFall where genuine allies fight, and contrast EnemyMine where the above sentiment proves true. Not TheMole, but may as well be. Often involves a ReliableTraitor.

%%* Sailors Uranus and Neptune in the "S" season (season 3) of ''Anime/SailorMoon''.
* ''{{Slayers}}'' The Slayers themselves ''know'' that Xelloss is only using them as part of a scheme to advance Mazoku interests, but between the facts that he's incredibly useful for the period of time where their goals coincide, and that they don't have any practical way of forcing him to leave, they have no choice but to put up with him.

[[folder:Comic Books]]
* In the MarvelUniverse, DoctorDoom once agreed to assist the ComicBook/{{X-Men}} by successfully healing Shadowcat when she was about to die from the effects of a fight with the Marauders, after Reed Richards had tried and failed to do the same. Doom didn't actually give a damn whether Shadowcat lived or died... he just enjoyed the opportunity to show up Reed Richards. This was also Doom's logic when he helped deliver Valeria Richards - her very existence would be a perpetual reminder to Reed that Doom was able to save his family when he wasn't.
* In ''SinCity'', Wallace gains the help of CorruptCop Liebowitcz who had previously been helping the Colonel, the head of an assassin guild. Despite Wallace beating up Liebowitcz's men several times and being a general annoyance, he agrees to help bring down the Colonel only because one of his assassins hurt his son.

* The Northern and Southern Water Tribes in ''FanFic/TheStalkingZukoSeries''. They attempt to present a united front to get better say in the peace conference. Otherwise, they despise each other. The Southern Water Tribe remembers that Northern Water Tribe didn't lift a finger to help them when they were being slowly killed off while the North thinks the South as poor, uneducated yokels.

[[folder:Film]]
* ''PiratesOfTheCaribbean'': Hector Barbossa helped out Elizabeth Swann, Will Turner and Jack Sparrow in the later films, but not because he liked them. More like Hector needed them to advance his own agenda.
* In ''Film/TheLordOfTheRings: The Two Towers'', the Ents help the people of the West by beating down Saruman not because they want to stop Sauron and destroy the ring (they specifically say that it's not their war), but because Saruman destroyed so many trees, and "A wizard should know better!"
* In the first ''AlienVsPredator'' film, Alexa Woods ends up teaming with the lone surviving Predator because she thinks it's the only way for her to get out of the situation alive (and she's right). The Predator's motive? He's still hunting the aliens, and hey, she proved herself useful in a fight and isn't an infected host so he may as well let her tag along if she wants to help him bag some more bugs.
* In the second ''{{Blade}}'' film, the vampire hit squad teams up with Blade to stop the Reapers. They still don't like each other, and each side takes great pains to antagonize the other. And the moment they get the chance, the vampires betray Blade.
* During screenings of ''TheRockyHorrorPictureShow,'' one of the quips audience members have been known to shout out is the malapropism "With friends like Riff Raff, you don't need enemas!"

[[folder:Literature]]
* In HarryTurtledove's ''{{Worldwar}}'' series, the various combatants fighting each other in World War II abruptly stop fighting each other and all turn their attention to fighting the alien invaders. The fact that they are all cooperating (to various levels) to beat back an outside threat does not make them friends (or even, in some cases, allies).
* When Griphook the goblin agrees to help Literature/HarryPotter break into Gringotts, he does so because he wants both to strike back at the human wizards who tortured him and to reclaim a lost goblin treasure and not because of any loyalty to Harry. Indeed, at his first opportunity, Griphook grabs what he wants and leaves Harry to escape on his own. Of course, Harry was ''also'' planing to betray Griphook by using the ExactWords of their bargain to withhold the treasure in question.
* Basically every good faction in the WheelOfTime. Each of them has her agenda, and while all of them oppose the dark ones, some of these consider the other ones to be allies of the BigBad, and everyone of these "know" better than the other how to stop the BigBad. It's not always evident to know what if the most harmful between the BigBad and the resulting struggles.

[[folder:Live Action TV]]
* Marya, the Russian spy from ''HogansHeroes''.
* In the Season Two finale of ''Series/BuffyTheVampireSlayer'', Spike helps Buffy stop Angel because 1) he wants Drusilla to himself, and believes that with Angel out of the picture, he'll have her all to himself again and 2) he rather ''likes'' the world (all his favorite activities and foods are there) and doesn't see much fun in the whole thing, himself included, being sucked into hell. He really couldn't care less if Angel ended up killing Buffy.
** Later, after he'd been implanted with an inhibitor chip that prevented him from harming human beings, Spike helped the Scoobies fight demons simply because he liked to fight, and demons were the only things he could hurt anymore. Eventually, the other demons pick up on this and he's no longer welcome among them so it ''does'' become more like a traditional EnemyMine scenario.
* In the ''Series/StarTrekTheNextGeneration'' episode "Legacy", the Enterprise crew enlists the help of Ishara Yar in order to rescue a lifepod full of space-freighter crewmen from a hostile faction on the DeathWorld Turkana V, only to find out in the end that Ishara Yar was using them as a covering force for her own mission: to blow up the fusion power plant belonging to that faction, so her own faction can gain supremacy.
** In ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'', the Romulans, Gorn, Tholians and Ferengi (all at least antagonistic toward the Federation and in some cases downright hostile) banded together with the Federation and Klingons (already long allied) in opposing the Dominion.
*** The Cardassians (and later the Breen) invert the trope, uniting with the Dominion to oppose the Federation and the Klingons.
**** From the Cardassians' perspective the Dominion fits, they obviously don't really trust or like each other (the Cardassians tried to wipe out the Dominion's homeworld only a year and a half before they allied), but [[LetsYouAndHimFight with Federation and the Klingons getting back together]], they have teamed up to fight the Federation and their allies in order to gain control of the Alpha Quadrant.
*** Garak is this on a more personal level. A true patriot ([[PlanetOfHats like all good Cardassians]]), he was banished from his home but still loves Cardassia with all of his heart, and sees Dominion rule as disastrous. As such, he will do anything to destroy the Dominion, and for most of the series that means working with The Federation. His main differing point with The Federation is one of method, Garak has no qualms against any method that might achieve his ends. He has been willing to start wars, commit genocide, and manipulate, assassinate and be accessory to the creation of chemical weapons in order to destroy the Dominion. Worst of all, he makes a good case for it.
*** Section 31 may also count. While acting in the interest of The Federation, they are willing to violate each and every single one its principles. The main characters of ''Deep Space Nine'' oppose them on the grounds that their methods ([[spoiler: which include an almost perfectly succesful extinction of the Founders]]) are everything they are fighting against.
** This was intended as part of the cast dynamic of ''Series/StarTrekVoyager'', with the Starfleet and Maquis crew united only in getting home. Of course, the crews merge almost flawlessly and immediately, preventing this except for a rare few episodes.
* Jerome in ''Series/HouseOfAnubis''. He's sneaky, manipulative, and uncaring, (at least at first). He does always end up helping Sibuna...but usually for his own benefit, or at least one that's different from the rest of the group's. Three seasons and he's still just an ally...an ally that none of them tend to even trust on a daily basis.

* In ''TabletopGame/{{Warhammer 40000}}'', the [[SpaceElves Eldar]] fight against whoever the current BigBad is, not ''along with'' the Imperium of Man.

[[folder:Web Original]]
* During the "[[AlienInvasion Xorn Invasion]]" storyline, one of the [[GlobalGuardiansPBEMUniverse Global Guardians]]' greatest allies against the alien invaders was Abyss, who normally is one of the team's greatest enemies. He helped them because the aliens were interfering with his own plans for world domination.

[[folder:Video Games]]
* In ''JadeEmpire'', Princess Lian starts out as this, but ends up joining your team and doing your bidding.
* [[LadyOfBlackMagic Morrigan]] of ''VideoGame/DragonAgeOrigins'' wants to stop [[TheEndOfTheWorldAsWeKnowIt the Blight]] just as [[PlayerCharacter the Warden]] does. . .but she also wants to [[spoiler: have a Grey Warden's baby that will serve as the vessel for the soul of an Old God, and will desert you before the final battle if you refuse to help her accomplish this.]]
** The [[VideoGame/DragonAgeII sequel]] has [[spoiler: Anders, who ends up using the PlayerCharacter as an UnwittingPawn in his scheme to blow up the Kirkwall Chantry and start a war between mages and Templars.]]
* Lord Yuan and the Renegades in VideoGame/TalesOfSymphonia, who fall into villainous territory because they feel Lloyd must be killed to guarantee their success, but whose aid is critical at several points in the story.
* Volke from VideoGame/FireEmblemTellius is an assasin, thief and mercenary in every sense of the word. His motives are never explained and he only gives information for a fee. When asked why he always needs money, he asks for 100,000 in pay to answer.
* In ''VideoGame/MassEffect3'', it would be a stretch to say that you can ally yourself to the Batarians in the fight against the Reapers. Its more like you get them to agree that, since you're fighting the Reapers, and they're fighting the Reapers, you might as well all fight them at once, on the same battlefield, at the same time.
** Taken UpToEleven with the eponymous Reaper-killer of ''[[{{DLC}} Leviathan]]''. It[[spoiler:, or rather they, are the [=MEverse's=] ''original'' AbusivePrecursors who used MindControl to rule over the 'lesser races' as gods until one of their creations turned on them, created the Reapers and started the cycles. They fight the Reapers because they are angry at losing their position as the 'apex of life' and care nothing for anyone else beyond the fact Shepard has proven they can no longer hide.]] Shepard may have found more help for the war, but what will happen when there's no longer a common enemy to fight is a pretty worrying question.

[[folder:Webcomics]]
* Anytime [[HeroicComedicSociopath Bun-Bun]] from ''SluggyFreelance'' is "helpful," it's a case of this. Quite often a key part of the MainCharacters' plans is to get Bun-Bun more pissed off at the bad guy than he is at them.
* Indirectly referenced by Maxim 29 from ''[[BigBookOfWar The Seventy Maxims of Maximally Effective Mercenaries]]'', from ''Webcomic/SchlockMercenary'': [[http://www.schlockmercenary.com/2003-03-08 "The enemy of my enemy is my enemy's enemy. Nothing more, nothing less."]]

* In the ''WesternAnimation/YoungJustice'' episode "Drop-Zone", Bane is willing to work with the Young Justice team in order to get his allies back. He winds up betraying them after this.
* On Creator/RalphBakshi's Creator/{{Terrytoons}} creation ''WesternAnimation/TheMightyHeroes'', an apartment tenant and his neighbor see [[DestructiveSavior the destruction the Heroes are causing during a battle with an enemy]] and says "With heroes like these, who needs enemies?"
* ''WesternAnimation/TheHairBearBunch'' episode "No Space Like Home" has Hair saying this about Bubi. Hair is made ruler of the planet Tarulia, but then Bubi--who speaks Tarulian (and any gobbledygook language) tells the natives that Peevly is their Earth leader. Hair is usurped for Peevly.

* The Soviets, the Americans and the British might have been allies against Germany in UsefulNotes/WorldWarII, but that doesn't mean the Soviets were ''friends'' with the British and the Americans. There was [[CommieLand a reason]] for that. What's more, it ultimately [[ColdWar came to a head]] after WWII.
** A similar thing happened with Finland. They fought on the side of the Axis and managed to avoid being turned into a Soviet puppet.
