History Main / DoubleAgent

* ''Manga/DeathNote'': Halle works for Near, but passes information to Mello. Near begins using her to feed Mello select information, since most of his deductions to that point are based on information generated by Mello's actions, and he assumes he'll find a way to take advantage of it if Mello works the same leads from different angles.
* ''Manga/MyHeroAcademia'': [[spoiler:Hawks, the #2 hero]], was secretly converted into the League of Villains by Dabi... except he's actually a Double Agent trying to infiltrate the League and gain information on them.
* Ryouji Kaji of ''Anime/NeonGenesisEvangelion'' is employed by NERV, SEELE, and the Japanese government to spy on and steal information from one another, while at same time pursuing his own goal: discovering the truth about TheConspiracy for himself. While none of the organisations are aware of his personal quest, NERV knows he's a double agent, SEELE suspects it, and the National Security Agency is relatively clueless. Eventually, one of the factions [[spoiler:(either SEELE or NERV, per [[WordOfGod Word of Anno]])]] gets sick of his backstabbing [[spoiler:and calls in a hit on him. He knew that they would do it, so [[FaceDeathWithDignity he just greets the killer and asks them what took them so long before he's shot dead]].]]

* In ''Manga/{{Bleach}}'', [[spoiler:Gin was working with Aizen to kill him-- Gin wanted to avenge the way Aizen had abused his OnlyFriend Rangiku. It took him [[BestServedCold a century]] to obtain both the information needed, and the actual opportunity itself, to make the assassination attempt.]]

* Taizou Kirihara in ''Anime/CodeGeass'', the head of one of the "Six Houses of Kyoto", a group of Japanese noble families that still retain power after Japan has been conquered, by supporting Britannian rule. However, Lelouch figures out that he's secretly the head of the Kyoto Group, which gives funds and supplies to resistance groups and offers to help the Black Knights. "A double agent... how cliche." [[spoiler: Kirihara also was behind the coverup of Prime Minister Genbu Kururugi's death at the hands of his 10-year-old son Suzaku, helping make everyone believe Genbu had commited {{seppuku}}.]]

--> '''Elizabeth:''' Whose side is Jack on?
--> '''Will:''' ...At the moment?
* In the film ''[[Film/EdgeOfDarkness2010 Edge of Darkness]]'', Jedburgh is a british national and "consultant" for the CIA who serves to clean-up politically damaging messes. Throughout the film, however, a seeming crisis of conscience and a liking for the protagonist makes it hard to pin down just where his loyalties truly lie.

* Taken to ridiculous extremes in ''Film/{{Cypher}}''. Almost every character is a double agent, to the extent you'll be sure that even the cleaners had a hidden agenda. And the protagonist [[spoiler:is.. well, let's see.. He starts as a spy for Digicorp, they brainwash him into a double agent to be planted at Sunways, but Sunways had the brainwashing sabotaged so he could be a triple spy, then he contacts Foster to become a spy for Rooks, then gets tempted into betraying Rooks for Digicorp as Rooks mole in Digicorp had planned all along, and then turns out to be Rooks himself playing all the others. So that's 6 times, a [[DoubleReverseQuadrupleAgent Sextuple spy]]. Yeah.]]
* ''Film/OperationDumboDrop'': Goddard, a Frenchman who keeps portraits of UsefulNotes/LyndonJohnson and Ho Chi Minh in a double-sided pictureframe.

* ''Film/TripleThreat2019'': Jaka pretends to align himself with Collins and his mercenary crew in order to gain their trust and destroy them, while assisting the defectors Payu and Long Fei.

* ''Literature/HarryPotter'': Severus Snape. His true allegiance is one of the Big Mysteries of the first six books, and, after frantic EpilepticTrees regarding the sixth book's ending, in the seventh it at last turns out [[spoiler: that he was GoodAllAlong, and that he helped Dumbledore because he was in love with Lily and felt guilty that she died because he was a Death Eater and was the one who related the prophecy to Voldemort]].

* In ''Literature/MaraDaughterOfTheNile'', the title character finds herself going from unimportant slave girl to one of these in a battle for the crown in about a day's time. It takes her most of the book to figure out who's side she's really one. Then, it's revealed that [[VillainousHarlequin Sahure]] is one as well.

** ''Literature/ShadowsOfTheEmpire'': Xizor calls together his Vigos (lieutenants) knowing one of them has been spying on Black Sun, then has Guri kill the spy, who's revealed to be the Human Vigo Green, once they all deliver the reports of their areas' earnings, after letting Durga the Hutt sweat to warn him against making any similar disloyal moves. He sternly lectures them first about how ungrateful it is to be betraying Black Sun, given how each of them enjoys significant power, status and wealth.

* ''Series/BurnNotice'': During the first half of season 1, Michael's friend and teammate Sam Axe got blackmailed into informing on him to the FBI with threats to his Navy pension. Michael figured it out almost immediately and, when he revealed he knew to Sam, he said it was better this way, because this means he can control the amount of information Sam feeds them to keep them from getting too deep in his business. Sam was relieved and happily agreed to this.
* ''Series/LeBureauDesLegendes'': Not suprisingly in an espionage thriller, there are several who qualify:

** Later, the Doctor engineers her escape from 1943 Paris by framing [[spoiler:the Master's German officer disguise]] for being a double agent, leaving him in a sticky situation being held at gunpoint while [[spoiler:she, Ada Lovelace and Noor Inayat Khan steal his TARDIS, forcing him to take TheSlowPath back to 2020]].
* In ''Series/EarthFinalConflict'', William Boone does this in season 1, becoming Protector to Da'an, whose loyalty is supposedly ensured by his brain implant. Except the implant was modified by LaResistance to remove that functionality. But while Boone works with the Resistance, he does not follow Jonathan Doors's orders blindly and he also enjoys a close relationship with Da'an, trying to understand Taelon culture. In seasons 2-4, the same role is taken by his ReplacementGoldfish Liam Kincaid, even more because Liam eventually becomes the RebelLeader.

* In ''VideoGame/{{Infernal}}'', there's some uncertainty for a while as to whose side Barbara Mitchell is on. She's part of [=EtherLight=], but friends with Lennox (who's now working for the opposition), and gives both of them the impression that she's on their side. She appears to be feeding Lennox information, but then is (unsuccessfully) insistent that Lennox should hand an electronic whatsit over to her without waiting for questions, and when Lennox is later captured, she is congratulated for tricking him. Then she helps him escape... but declines to join him, claiming that she can be of more use pretending to be loyal to [=EtherLight=]. It's only when a soldier catches her transmitting to Lennox, and Lennox subsequently rescues her, that she makes her allegiance (with Lennox) clear to everyone.
* Ada Wong in the ''Franchise/ResidentEvil'' games plays both sides so many times that nobody's even sure what side she is on. Starting in ''VideoGame/ResidentEvil2'' (which is her debut appearance), she pretends to be a civilian looking for her boyfriend in the ZombieApocalypse, only to be revealed as a spy sent to recover the G-Virus. Because Leon kept going out of his way to protect her and even taking a bullet for her, she warms up to him a bit and tosses him a rocket launcher at the end of the game to take out the recurring monster that's been stalking him the whole game (Claire gets the same help if she's the player character in the "B" scenario). ''VideoGame/ResidentEvil4'' has her working for [[BigBad Wesker]] to obtain a sample of the Las Plagas and is ordered to kill Leon. She still does her job, but she discreetly helps Leon out without him knowing and in the end, she tosses down a rocket launcher to him so he can finally take out the cult's leader. Ada forces Leon to give him the sample at gunpoint, but she gives him keys to a jet ski so that he can escape the island. By ''VideoGame/ResidentEvil6'', she appears again working for a new organization involving the C-Virus and helps Leon and the other main characters out when she can. Her cloudy alliance gets lampshaded when Helena asks if Ada can be trusted, only for Leon to respond that it's not an easy question to answer.

* Gaea from the ''Franchise/{{Noob}}'' franchise, while a self-serving ManipulativeBastard, is still nominally part of the Empire and the Noob guild thanks to game mechanics. She also works with the hacker who wants to drive players out of the game for in-game currency and other perks. Then, thanks to a FrameUp, a bunch of Coalition players get convinced that she's a double agent loyal to the Coalition. Gaea never sets them right because extra players that can take the bullet for her are always a good thing from her point a view. This situation gets an extra level of complexity when [[spoiler:Gaea eventually joins the Coalition, but her second gaming avatar remains an Empire and Noob guild member]], but the closest she ever gets to actual spying is getting paid to give the Empire top guild information about the hacker.

* In the last 3 special episodes of season 3 of ''WesternAnimation/TotallySpies'', Dean, a fellow WOOHP agent and one of the few hot guys that all of the three girls fall for is revealed in the second episode to be a double agent working for Terrence, Jerry's twin brother who changed his face in resentment of him, to revenge on Jerry and destroy WOOHP, only to be revealed to be a "quadruple agent" (as said by Alex) in the third episode. He says he had to switch side to keep the girls safe, which makes no sense whatsoever (other than being a ridiculous plot twist) because he literally left them to die earlier, not to mention that he backpedals immediately and says "I knew you'd find a way out somehow," not to mention again even Terrence himself also somehow manages to get a Jerry mask under his face mask and over his real face, which fools a guard to let him out of custody at the end of the episode. Not as absurd as a Main/DoubleReverseQuadrupleAgent, but still absurd.

* In one of the greatest intelligence success stories of all time, the British managed to turn literally every German spy in Britain to their service early in UsefulNotes/WorldWarII, then used the German intelligence network in England as a massive puppet show to deceive Germany about Allied strength, strategy, and goals. And since they had all the current German infiltrators turned, they always knew when new ones would be snuck in, and captured them immediately. The captured spies would be given the option to join in the sending of false info, or be executed. Some would be kept out of circulation anyway, because the Germans obviously would have gotten suspicious if ''none'' of their spies were ever caught. Admittedly, at least in the case of the UsefulNotes/{{Abwehr}} agents, a lot of them probably switched sides willingly with the hope of bringing down the Nazis.
** One in particular, Juan Pujol Garcia, a.k.a. "[[http://mentalfloss.com/article/58468/most-amazing-lie-history GARBO]]," set out very early on to become a Double agent; he conned his way into Nazi Intelligence, and used that to get into British Intelligence (his real goal). He played a critical role in ensuring that D-Day was a success. He fed the Germans such a wealth of false information that they actually ''[[https://en.wikipedia.org/wiki/Juan_Pujol_Garcia#Honours awarded him the Iron Cross for his efforts]]'', and four months later King George VI awarded him an [[UsefulNotes/KnightFever MBE]], meaning he may be the only person to have received honors from both the Axis ''and'' Allied sides of World War II.

The guy who's TheMole on both sides of a conflict. He works for both sides and plays them off against each other. Although often shown as a villain, he can also be a likeable rogue who just happens to have flexible loyalties, or who has problems with both sides and enjoys setting them on each other. He can even be loyal to one side, and willing to engage in the DirtyBusiness of faking being an agent for the other; TheMole who engages in BecomingTheMask may turn into this.

* In WebVideo/ShortsWars, cdotkom "Charlie" is friends with the Shorts creators, until later they find out that he has been secretly working with The Boss the whole time and actually betrayed them. Little did they know, that cdot was actually working *against* The Boss the whole time, and [[spoiler: was actually the one who saved [=RoyalMelon=] from the explosion, leaked the logs that would later reveal The Boss' true identity and backstory]] and even helped the other creators destroy the second facility in the end.

-->-- ''Series/BurnNotice'', "Hard Bargain"

[[caption-width-right:213:The whole cult is like this...]]

%%* Sam Axe did this for a while in ''Series/BurnNotice'', though not by choice.

* In ''WebAnimation/HowItShouldHaveEnded'', [[Literature/HarryPotter Snape]] explains that he's actually a double agent who helped Voldemort until he was at an opportunity to be killed, then goes back in time stop Voldemort from ever existing.

* ''WesternAnimation/CarmenSandiego'': Near the end of Season 2, we're introduced to Roundabout, a [[NebulousEvilOrganization V.I.L.E.]] operative planted high-up in British intelligence, a position he uses to keep V.I.L.E. one step ahead of law enforcement. He proves efficient enough at his job that [[spoiler: he's chosen to fill the [[EvilPowerVacuum empty seat]] on the [[BigBadDuumvirate V.I.L.E. Faculty]]]].

* Taken to ridiculous extremes in ''Film/{{Cypher}}''. Almost every character is a double agent, to the extent you'll be sure that even the cleaners had a hidden agenda. And the protagonist [[spoiler:is.. well, let's see.. He starts as a spy for Digicorp, they brainwash him into a double agent to be planted at Sunways, but Sunways had the brainwashing sabotaged so he could be a triple spy, then he contacts Foster to become a spy for Rooks, then gets tempted into betraying Rooks for Digicorp as Rooks mole in Digicorp had planned all along, and then turns out to be Rooks himself playing all the others. So that's 6 times, a Sextuple spy. Yeah.]]

* In ''WesternAnimation/CodenameKidsNextDoor'', KND operatives are sent for [[LaserGuidedAmnesia decommissioning]] once they reached [[ThirteenIsUnlucky thirteen]]. In one episode, Number 5's former teammate Maurice, explains that the best and trusted operatives are exempt from decommissioning, allowing them to continue helping the KND from opposing sides.
