Storm Shadow: So why do you keep [the mask]?In any war, there are those that will benefit from the fighting and destruction that it causes. This trope is about when somebody realises this and dupes or manipulates a couple of different groups into fighting each other so that they can turn the chaotic scenario to their advantage. They could be plotting to take over one of the factions once the war's finished. They could be trying to get one side to change from being a neutral party into an ally or perhaps they are trying to use the situation to look good, making the outsider seem like the reasonable party for their involvement in the conflict. Maybe they just want to use the war as a diversion so they can carry out their own plans. There are many ways to benefit, but the crux of the trope is that there is a conflict and somebody has plotted to make that conflict for their own benefit. Supertrope to Divide and Conquer, which is specifically getting groups to fight to wear each other down so that the plotter can conquer them more easily, and War for Fun and Profit, when someone plans to make money and/or gain amusement from the conflict. Related to the Batman Gambit, since this trope will often rely on some behaviour predictions and Flaw Exploitation and the Kansas City Shuffle because such a plan is very dependent on misdirection. If the planner can still benefit by the misdirection failing, then it could be a Xanatos Gambit. This is a risky Evil Plan to attempt, but not without backup perks. Should one side realize they're being played, they could turn against the manipulator, who in turn could "ally" himself with the remaining side for safety purposes. It would also continue to perpetuate the conflict while the manipulator prepares to reap the rewards (best-case scenario) or get out of dodge (bad scenario). An even rarer collapse involves both sides catching on and deciding that life would be better without the manipulator. This worst-case scenario is usually solved with the manipulator getting as far away from the now-incensed ex-pawns as possible, if such a possibility is available. If not, the manipulator will likely succumb to the temptation to cancel their own subscription to life. If a leadership of both sides is Playing Both Sides, that's Running Both Sides. Overlaps with False Flag Operation.

Anime and Manga
- Ghost in the Shell: Stand Alone Complex: Kazudo Gouda plays both sides to incite rebellion in the refugee population of Japan and overthrow the Japanese Government. People would be brainwashed into suicide terrorist attacks on the refugee, then the phenomenon of "Blame the victim" would be stirred up in the main population to bring up resentment against the refugees. Eventually the refugees would be tricked into making an attack to cause the government to hit back and shift to an isolationist and militaristic policy.
- The plot of the Digimon Frontier movie was this. The villain started a race war to get humanoid Digimon to fight animalistic Digimon to unseal an evil in a can. Notably, the villain was able to pose as the leaders of both military factions.
- Transformers Armada: Sideways, working for Unicron, who is manipulating the conflict between the Autobots and Decepticons in order to encourage the hatred and anger of both parties so that Unicron can feed on it and become reborn. The Mini-Cons themselves, supposedly the all-powerful MacGuffins of the series, were specifically created so that the Transformers would fight over them.
- In One Piece, Crocodile manipulates Alabasta into a civil war.
- Bahbem was playing both sides of the Human/Mulian conflict in RahXephon. He helped the Mu develop their Dolems and find ways to work around the dimensional barrier, whilst also setting up TERRA to fight off any Mulian incursions. He didn't really care which side won, as long as it created an environment that would get the RahXephon to activate.
- Gundam: Anaheim Electronics from the Universal Century timeline is a milder example; they don't try to start wars, but they're more than willing to sell their mobile suits to both sides in a conflict, regardless of any sort of moral complication (like say, the fact that the people they're selling to want to kill half the human population). A prime example of this comes in Gundam 0083: Anaheim builds three Gundams for the Earth Federation, then gladly sells the fourth (modified to look like a Zeon MS) to the Delaz Fleet after the Federation passes on buying it. A partial justification comes in the background info, which says Anaheim absorbed Zeon's old MS development firms after the One Year War, and thus has many members who are still loyal. This attitude of theirs is a major reason the Federation eventually creates SNRI, their own in-house Mobile Suit production company, so they don't have to rely on Anaheim exclusively.
- Haman Karn near the end of Zeta Gundam. When Axis Zeon makes a surprise return in the midst of the Gryps Conflict, both the AEUG and Titans try to get her to join their side.

Then Doom gave Slovakia weapons to attack the other country but then used this as a pretext for his country, Latvaria which neighboured the other two, to intervene (i.e. invade) since the Avengers could not do so unbiasedly.
- One of Batman's Gambit Roulettes blew up in his face when Stephanie Brown tried to implement it to prove herself after he fired her as Robin.

The Grey Spy would often sucker White Spy and Black Spy into fighting each other, sometimes over her affections, and usually profit from it by either offing both of them, stealing the MacGuffin out from under their noses, or swindling them both with shoddy war materials.
- Transformers fiction features the aptly named Doubledealer, a mercenary who hires himself out (discreetly) to both sides of the war so as to benefit himself.

Orlov points out that Weisz sold to both sides in the Iran-Iraq War, prompting the latter to reply that he wanted "both sides to lose".

- Genestealer cults too: They usually infiltrate and manipulate both the government and dissident groups to cause a continuous world-wide civil war until the hive-fleet arrives.
- The Followers of Set do this a lot in Vampire: The Masquerade. Because of a mix of ideology and pragmatism, Setites prefer to stay out of the fighting between the Camarilla and the Sabbat, except when it comes to making backroom deals for supplies and secrets.

- In Grand Theft Auto III, Donald Love has the player incite a gang war between the Colombian Cartel and the Yakuza in order to bring down real estate prices.

In Mr. House's case, he also wants to make sure that the NCR's defeat is mitigated, as he needs their tourism for his own economy.
- The Doom series has monsters that are programmed to fight one another if you can get them to either blast/wallop each other or if you splash them and trick them into fighting other demons. This allows a player to clear seemingly impossible scenarios, like the room with the Cyberdemon and 18 Barons of Hell. Additionally, some monsters just plain don't like each other, such as the Baron of Hell and the Cacodaemon, a feud lampshaded in the original Doom.

Though the Obligatory Pirates remain out of sight during the war you incite, it's possible to get them to strike the finishing blow, bombing them all back to the stone age.
- Deus Ex: Invisible War allows the player to do this between the WTO and The Order. Turns out to be subverted, because the Illuminati is actually running both sides. Later, the player can play this straight with the Illuminati, the Templars, and Apostle Corp.

However this plan gets snuffed when Altaïr addresses King Richard directly at Arsuf and calls out de Sable's plan, to which Richard actually acknowledges Altaïr's claims and allows God to sort out whose position is correct by pitting de Sable against Altaïr in armed combat, to which Altaïr obviously wins.

- Buck Godot: Buck does it in multiple arcs. A great one is at the end of the Psmith arc, where he starts off with playing two sides while both of them are standing right next to him. The Psmiths believe him, Der Rock the Destroyer doesn't. Which turns out to be a mistake, since he was being truthful to Der Rock. But that was exactly what Godot was counting on. It ends with him getting paid by Der Rock (since he had done the job he was supposed to) getting paid for the job the Psmiths were supposed to do (but failed to because of Godot trickery) and getting paid for aiding in the capture of Der Rock (without actually betraying him, he got himself captured by not believing Godot.)

- Numerous countries took aid from both the United States and the Soviet Union during the Cold War.
- In a related example from the same time period, Ho Chi Minh took advantage of aid and equipment from both the People's Republic of China and the Soviet Union during the Vietnam War. He was able to get away with it because the PRC and USSR had been at each other's throat for some time by the mid 1960s, but the US and NATO had not yet discovered the 'Sino-Soviet split', and both countries wanted to project an image of unified world communism to the West. Being the master manipulator that he was, it is likely that Ho knew this and the whole scheme was a deliberate Batman Gambit.
- A few wars in Ancient Greece (e.g. The Corinthians during the Peloponnesian War) began with a such a plot. Typically, side A would deviously provoke a proxy of side B to invade one of their own proxies. Side A thus gained a pretext to invade the proxy of side B, prompting side B to declare all-out war on side A. The advantage was that, in the heavily morally charged political climate of Classical Greece, side B would appear to have been the aggressor.
- Zeno, Emperor of Byzantium, pulled off one of these in A.D. 488 when he induced Theodoric the Great, King of the Ostrogoths, to invade Italy, which was then held by King Odoacer. Both men were nominally servants of the Emperor but actually independent rulers who were constantly causing trouble; by getting them to go to war with each other, Zeno ensured that the Empire would be rid of at least one set of troublemakers, no matter which side won.
Could be considered an instance of Divide and Conquer, except that the Emperor didn't follow up his successful gambit (Theodoric won) with a conquest of the Ostrogoths. Although, a few decades later, Justinian did manage to conquer the Ostrogoths and much more.
- During the Spanish Civil War, Polish government sold (mostly obsolete) arms and equipment to both sides of the conflict. Although one could expect a right-wing military dictatorship to support Franco only, more weapons were actually delivered to the Republican side. This is understandable considering how dire was Poland's geopolitical situation at the time and how desperately it needed funds to modernize its own army.
