-> ''"Suspicion that a character, once thought trustworthy, may not be trustworthy!"''
-->-- '''Wealthy Successful Protagonist (Who Is Handsome)''', ''WebVideo/ATrailerForEveryAcademyAwardWinningMovieEver''

This describes a person, who may be a ManipulativeBastard, a BitchInSheepsClothing, AlphaBitch, etc. who gets close to you and pretends to be your ally, friend, lover, etc. Basically, they earn your trust, and when you least expect it, they betray you and reveal they've merely been playing you this whole time. Another variation on this is that the manipulative character may find himself BecomingTheMask, developing real feelings for the person he betrayed. Sometimes, the betrayer may turn out to be someone you've known pretty much your whole life.

If a character with a FriendlessBackground ''finally'' finds a person who appears to believe in him or her, and then that person turns out to be a False Friend, it's almost certain that the character will then have crossed the DespairEventHorizon.

TheMole is perhaps the best-known practitioner of this brand of betrayal.

Closely related to WasItAllALie and IJustWantToHaveFriends. Can lead to an EtTuBrute situation. If the False Friend turns out to be the guy behind ''everything'', he's a BigBadFriend. Contrast TrueCompanions. The polar opposite of both VitriolicBestBuds and WithFriendsLikeThese if true friends are always mean to each other but still remain friends. If it's about a character revealing their hatred for another during a fall out, then it's HiddenDisdainReveal.

Not to be confused with [[http://en.wikipedia.org/wiki/False_friend the term in linguistics]] for [[InMyLanguageThatSoundsLike words in two languages which look similar but do not mean the same thing]]. ("''Embarazada''? But… I trusted you!")

* ''Manga/ElfenLied'': During Lucy's childhood, she made friends with another girl who promised to keep the fact that Lucy was taking care of a puppy a secret from a group of boys who frequently bullied her. Eventually, the boys found out about the puppy and [[MoralEventHorizon beat it to death in front of Lucy while making her watch]]. It turns out the girl Lucy made friends with had ''deliberately'' told the boys about the puppy, and while she's pretending to cry about it and feel bad about what she did, we see her ''smile'' through her crocodile-tears. Lucy then snaps forever and '''[[DisproportionateRetribution kills]]''' [[KarmicTwistEnding her along with the bullies]]. It is however left somewhat ambiguous if that was the case. It's [[AlternativeCharacterInterpretation possible]] [[UnreliableNarrator Lucy imagined the smile]] and the girl really didn't know the boys were gonna do that to the puppy.
* ''Anime/PeachGirl'':
** Sae to Momo for the first couple of volumes before the two genuinely become friends.
** And Sae gets a taste of her own medicine when she falls for Ryo, who's just as manipulative as her. The betrayal part comes into play when he sets Sae up to do a porn video without her knowledge. Thankfully, Momo saves her.
* ''Anime/{{Gankutsuou}}'':
** In the beginning The Count seems to like Albert when in reality he only views him as a tool for his revenge. [[spoiler:However, as time goes on, he finds himself developing real feelings for Albert which cause him lots of angst and heartbreak, but ultimately save him in the end.]]
** Also, Peppo to Albert. Though [[AmbiguousGender she/he (?)]] eventually develops actual feelings for him.
* ''Manga/{{Naruto}}'':
** Kabuto usually presents himself as this harmless, bumbling oaf with NerdGlasses, but is in fact the subordinate of the BigBad Orochimaru, and Naruto seems clearly angry and upset when he realizes this because he had originally believed Kabuto was on their side since he helped them by giving them information and the like.
** Shiranami to Hotaru in the Six-Tailed Beast arc.
** Also, Yashamaru, Gaara's uncle. At first, Gaara thought that he was the only one that cared about him. Yashamaru taught Gaara about physical pain, emotional pain and love; concepts Gaara was completely unaware of in his childhood. He was commanded by the Fourth Kazekage to assassinate Gaara, but was given the choice in deciding whether he wanted to proceed or not. Yashamaru willingly accepted the command in order to avenge his older sister's premature death. The assassination attempt, however, ended in a desperate suicide mission and ultimately failed. Before he died, he told Gaara that no one had ever really loved him, not even him. This left Gaara even more of an emotional wreck than he already was. His suicide bombing attempt on Gaara's life caused Gaara to become psychotic. Yashamaru's last words, to Gaara, were "This is it. Please die." It's revealed much later that [[spoiler:he ''truly'' did it under the orders of the Fourth Kazekage (Gaara's dad) as part of a SecretTestOfCharacter, and that he had objected to such a move but ultimately had no choice.]]
** In the second ''Shippuden'' movie Shinnou turns out to be one for Amaru. Amaru is quite shocked, but separates the person who taught her medicine and served as an inspiration to save lives and the person who is the BigBad.
** Tobi and Nagato worked as allies as the true powers of Akatsuki. But after Nagato's death, Tobi shows [[HiddenDisdainReveal frank contempt for Nagato]], saying that Nagato just too easily influenced and merely complains about needing another pawn. And later he revealed to Konan that he had been using Nagato's ideals and his quite understandable hatred against the people to control him.
* ''Manga/{{Bleach}}'': Aizen [[spoiler:does this when stabbing Hinamori while hugging and praising her, as well as betraying everyone in Soul Society (who adored him) after revealing the fact that he has always been against them]].
* The first time you properly see Izaya Orihara in the ''LightNovel/{{Durarara}}'' anime, he spends most of the episode having a suicidal and unstable girl named Rio, that he pretended to sympathize with and be friends with online, kidnapped and then orchestrating her rescue, only to hold poor Rio over the side of a building, toy with her desire (or lack thereof) to actually commit suicide, and then wander off to watch from a distance as Rio's despair reaches its peak and she decides to jump anyway. Luckily for her, Celty was a little more worried about her safety and saves her.
* ''Manga/HotGimmick'': Azusa does this to Hatsumi, making her fall in love with him before trying to have his friends gang rape her out of revenge.
* ''Manga/DeathNote'':
** Light Yagami is quite fond of this trope. The most notable victims of his manipulations are Misa Amane and Kiyomi Takada. Each woman was [[{{Yandere}} incredibly in love with him]], but Light, as with all of his allies, [[YouHaveOutLivedYourUsefulness found them disposable]].
** L, as a heroic example, counts as that towards Light and Misa, probably. "So now I've gained yet another friend..."
* Sakurako Sanjou of ''Manga/BoysOverFlowers'', who in all continuities (manga, anime, drama) befriends [[PluckyGirl Tsukushi Makino]] and looks like a kind, shy, cutesy type... at least up until she has Tsukushi drugged, takes pictures of her unconscious in compromising positions and distributes them freely among the school, leading to her assault by other students. This is revealed to be [[EvilPlan her master plan for seducing/revenging herself upon Domyoji]], Tsukushi's SlapSlapKiss-y love interest, which also involved her spending a fortune on plastic surgery, dropping out of school in the past, and hiring professional goons to assault ''various'' characters (not only Tsukushi). The reason for all of this is that ever since she was in kindergarten, Domyoji [[DisproportionateRetribution bullied her and called her ugly]]. She does eventually get some much-needed CharacterDevelopment, however, and becomes more of a GoodIsNotNice JerkWithAHeartOfGold case.
* Griffith of ''Manga/{{Berserk}}'' was ''never'' a nice guy, even before his FaceHeelTurn. A good example of this is how he treats Princess Charlotte, who's genuinely in love with him, as a MealTicket while still pretending to be in love with her. The only person he was remotely honest with was Guts. He has a catastrophic breakdown when Guts leaves the Hawks due to wanting to stand on even ground with him and feeling that he was unable to as his subordinate.
* Kyouko Mogami of ''Manga/SkipBeat'' initially followed her childhood friend Shou to Tokyo to help him to get into a music career. Although Shou didn't help her at all and mistreated her, Kyouko still believed that all her efforts (doing several part-time jobs, paying for his training, being his de-facto unpaid maid) would be eventually repaid with love and gratitude. (Plus, Shou's parents were considering to make ''her'' the heiress of the family business instead of Sho.) Until she learns, from the mouth of Shou himself, that he has no feelings towards her, and the only reason he asked her to come with him was because he knew she would act as his personal maid for nothing. So she snaps, decides not to take it anymore, and makes the resolve to get revenge on him by trying to become as famous as him.
* Otome's "friends" Natsumi, Minami and Kumi do this to her in ''VisualNovel/SchoolDays''. Otome is betrayed by them twice: they first [[spoiler:videotape her having sex with Makoto, the guy she likes, and show the tape ''to the whole school'']], [[note]]This only happens in the anime, in the games it's Nanami's rival Chie who does it[[/note]] and then [[spoiler:they have sex with him behind her back.]][[note]](In the anime it's set on stone, but it's optional in the games)[[/note]] And they do this '''for no reason at all.'''
* ''Manga/BetrayalKnowsMyName'':
** Uzuki to Yuki. As he himself tells Yuki in episode 2 "You're a nuisance. I hate your goody two-shoes, know-it-all act. I'm not your friend. I felt bad for you, so I thought I'd try being nice, but you misunderstood. ''No one needs you.''" But its refreshingly subverted when its revealed Uzuki was just deeply hurting from being abandoned by his parents and lashed out at others. He and Yuki become friends again after Yuki gets rid of the demon that was possessing Uzuki and feeding on his negative emotions.
** And in episode 12 Kanata, Yuki's best friend, does this when he reveals to Yuki that he is actually the BigBad Reiga.
* ''Anime/CodeGeass'':
** Rolo, Lelouch's fake little brother, was actually a teenage assassin charged with the task of keeping an eye on Lelouch in case he regained his old memories. When Lelouch found out, he continued treating Rolo kindly and orchestrated a situation where Lelouch could pretend to risk his life to save Rolo, winning his trust and bringing him over to his side. After Lelouch's real sister died [[spoiler:or so we think]], he admitted to Rolo that he was just using him, actually hated him, and had tried to kill him on several occasions. Nevertheless, without being asked or influenced by Lelouch's Geass, Rolo sacrificed himself to protect Lelouch, since he believed that even when Lelouch lied to him, ''his'' own love for Lelouch was sincere.
** And [[spoiler:Empress Marianne]], [[spoiler:Lelouch]]'s mother, [[spoiler:whom he looked up to and adored]] is revealed to actually be [[spoiler:quite the MagnificentBitch]].
* ''Anime/RevolutionaryGirlUtena'':
** Akio is TheCasanova to the extreme and does this to a lot of people, most notably to Utena. Another example is when Nanami walks in on her beloved brother Touga making out with a member of her old gang, Keiko, and overhears him say he never loved her to begin with, and her ex-friend claims she has no connection to her anymore either.
** Touga is actually very good at this, and his other victim aside of Nanami is Saionji. Yes, Saionji was a JerkAss, but not even ''he'' deserved Touga's horrible treatment.
* In the yaoi manga ''Manga/UnderGrandHotel'' an inmate named Norman is in love with Swordfish, who is in love with Sen, but pretended to be in love/friends with Sen so he could get closer to Swordfish. He tried to persuade Swordfish to kill Sen but that didn't work. So, on one occasion when there was a scuffle going on he tried to get Sen out of the way by stabbing him with a pencil but accidentally ends up stabbing his inmate Walter instead who was trying to protect Sen in the hope of getting protection from Swordfish. When he finds this out, Norman holds a knife to Walter's neck telling him, "If you don't want to die, don't butt in again Walter!"
* In ''Manga/PandoraHearts'', [[spoiler:Jack Vessalius]] turns out to be this to [[spoiler:Arthur Barma in the past and Oz in the present]]. It can be argued that he was also this to [[spoiler:Oswald/Glen]], though it's very possible the two were genuine friends before [[spoiler:Lacie's death drove Jack insane]].
* In ''Manga/SakuraGari'' Sakurako passes herself off as a kind-hearted SatelliteLoveInterest to Masataka (who genuinely starts falling for her). Unfortunately for him, she's a scary [[spoiler:and thoroughly broken]] {{Yandere}} who actually hates him and is [[BrotherSisterIncest incredibly possessive of her brother]].
* Lancia of ''Manga/KatekyoHitmanReborn'' is a young Mafia boss who took Mukuro Rokudo in as a child. However he was betrayed and brainwashed by Mukuro's HypnoticEyes, which forced him to kill his entire family.
* ''Manga/OnePiece'':
** Kuro does this to Kaya as part a lengthy scheme to gain her trust so he can claim her fortune and retire from piracy. When Kaya finds out his true nature, he freely admits that he ''hated'' having to act the kindly butler to her.
** It is again used by the [=CP9=] as they act friendly, become well-loved members of Water 7, befriend many members of Dock 1, including Paulie, but when they reveal themselves, they also reveal that they never had any attachment to the city or to the people inside it. Paulie can't believe it at first, and asks his traitorous good friend Rob Lucci:
--> '''Paulie:''' ...I thought...!! I REALLY THOUGHT WE WERE FRIENDS!!!\\
'''Rob Lucci:''' [[WasItAllALie Only you thought that]].
** It was used during Alabasta by the crime boss and Shichibukai, Crocodile, with him pretending to be aiding the dying sand kingdom by killing any invading bands of pirates and purporting himself as fighting for the people, when in reality he was just goading them so he could use his organization known as Baroque Works to destroy them from the inside and have their king show him the FantasticNuke that their country is hiding.
* When Riff from ''Manga/CountCain'' has his confusing [[spoiler:FaceHeelTurn and "dies," it is revealed that Riff, the manservant ''personality'' was never actually real]]. This is Cain's manservant by the way, the only one who can "see his scars, make his tea, and tie his shoelaces." Epic TearJerker.
* [[spoiler:Haruko]] turns out to have been playing her friend from the start in ''Manga/SchoolMermaid'' as part of a horrific BatmanGambit.
* ''Manga/HighschoolOfTheDead'': The first chapter/episode has two girls, Toshimi and Misuzu, proclaiming their friendship while running hand-in-hand as they attempt to escape the zombies overunning their school. That is, until Toshimi gets caught unexpectedly and is promptly abandoned to die by her "friend" Misuzu, who kicks the other girl to force her to let go of her hand so she could save herself. [[KarmicDeath But Misuzu is immediately caught and killed, as well.]]
* ''Anime/LupinIIIIslandOfAssassins'': [[spoiler: Doc]] literally [[ChronicBackstabbingDisorder made a career]] out of ingratiating himself with various partners, only to stab them in the back [[YouHaveOutlivedYourUsefulness once it was convenient for him.]]
** Years prior to the start of the film, he was Lupin's old partner before meeting Jigen. That ended the day he shot Lupin during one of their escapes, with his own Walther P-38, then left him for dead.
** He also spent years pretending to care about [[BrokenBird Ellen]], despite being responsible for her brother's death (unbeknownst to her). Once he no longer needed her, he conspired with Gordeau to have her [[KillEmAll and the other defectors mass murdered.]]
** Gordeau wasn't exempt either, since [[spoiler: Doc]] knew he was planning to turn on him once everything was in place. So he beat him to the punch by giving him a fake antidote, then shot Gordeau while he was suffering from the toxin.
* Sara to Yuuri in ''LightNovel/KyoKaraMaoh''. However, Sara does save Yuuri after betraying him and they become friends again, subverting the trope.
* In the backstory of ''Manga/SpecialA'', Akira's childhood friend Sayo only hung out with Akira because she was rich. Yahiro, a ''real'' friend to Akira, drove Sayo away to protect Akira but let Akira believe he did it because he was just being a jerk to spare her the truth. In the present she still hates him.
* ''Manga/AttackOnTitan'' uses this as one of the major twists of the series, giving the cast and audience a solid GutPunch in the process. It's made even more [[TearJerker painful]] by the revelation that even though [[spoiler: Reiner, Bertolt, and Annie]] were [[TheMole spies]] and [[BigBadFriend responsible]] for much death and suffering, the bonds of [[TrueCompanions friendship]] were [[BecomingTheMask genuine]]. Eren [[HeroicBSOD reacts]] [[RoaringRampageOfRevenge about]] [[YouMonster as well]] [[ItsPersonal as can]] [[YouKilledMyFather be expected]].
* ''Manga/AkagamiNoShirayukihime'': At thirteen years old prince Zen finally made his first friend after his position had left him isolated from anyone who didn't want to use him for his title. [[spoiler:Unfortunately this friend only befriended him as part of an assassination attempt and Zen couldn't try to kill him even after the plot was revealed and his "friend" was making a legitimate attempt on his life. He was saved by his older brother and the knight Mitsuhide, who became his true first friend even if Zen was unable to ever stop considering the traitor as such]].
* ''Anime/{{Hamatora}}'': [[spoiler: In the new season, it has Art, who used to be Nice's friend, but turned against him and his friends.]]
* This trope was {{conversed|trope}} in Chapter 8 of ''Manga/MonthlyGirlsNozakiKun'', animated as the first half of Episode 4. Nozaki was initially unwilling to consult [[MrExposition Tomoda]] when playing Mikoshiba's DatingSim as he sees anyone who appears to be friendly to the protagonist in fiction to be this--after all, Nozaki is a ShoujoGenre author by trade. After a brief explanation of the trope itself by Nozaki, Mikoshiba complained Nozaki for being WrongGenreSavvy.
* An early chapter of the horror manga ''Presents'' focused on two girls, Rinko and Suzuko. Everyone said the two were great friends, but what they (and Suzuko) didn't know was that Rinko only befriended Suzuko because she thought Suzuko made her look better by comparison. As time went on though, Suzuko slowly started becoming more confident without losing her friendly demeanor, and Rinko became desperate to knock Suzuko down a few pegs. Although in all honesty, it's more that Rinko's inferiority complex coupled with the fact that she was now suffering from an outbreak of zits was making her more paranoid about Suzuko (not helped by Suzuko's naturally flawless skin). She gives Suzuko tainted perfume, which causes Suzuko to develop horrible boils on her face. KarmicTrickster Kurumi appears to help Suzuko, realizing Suzuko really is as innocent as she appears, and helps her deliver a "return gift" to Rinko. Kurumi reveals to Suzuko just how much of a giant bitch Rinko is, and the return gift is Suzuko's despair and feeling of betrayal transferred to Rinko. This restores Suzuko's face to normal, and gives Rinko boils alongside her acne.
* ''Manga/MoonSubaruSolitudeStanding'' has Minmin's friend from acrobat school. He was friendly towards her when she was homesick and showed her how much fun being an acrobat can be, as well as how it helps send money to her poor family. The two even start a romance going on, but Minmin realizes that his friendship was a setup by the school's higher ups. He was supposed to manipulate her into not leaving, no matter how.
* Manami from ''Manga/{{Life}}'' is introduced as a classmate who befriends the introverted and depressed Ayumu. It soon becomes obvious she is simply trying to manipulate and bully Ayumu. She's the closest thing to a BigBad the manga has.
* ''Manga/FrankenFran'': One chapter has Veronica go to a school, where everybody picks on her except for one girl, who invites her to her home. [[spoiler:She actually works for a pedophile ring, attracting young girls to be sold overseas. After Veronica slaughters the men, she spares the girl's life... leaving her to work out how to explain the corpses in her apartment.]]
* In ''Manga/Brave10'', [[spoiler:Anastasia upon her FaceHeelTurn]] reveals the friendliness was all an act to get [[TheMole information]].
* ''Anime/MobileSuitGundam'': Char Aznable spends years pretending to be Garma Zabi's friend, but sets him up for defeat and [[spoiler: a brutal death]] at the hands of the White Base, and [[KickTheDog gleefully admits to the betrayal]] [[spoiler: during Garma's final moments]]. It was all part of his plan to destroy the Zabi family one by one.
* ''Manga/NatsuENoTobira'' has one of Marion's three friends playing the trope to him: [[spoiler: none other than [[EeriePaleSkinnedBrunette Lind]], who was so DrivenByEnvy regarding [[TheAce him]] that, when Marion became the lover of [[YourCheatingHeart a married woman]], he decided to sell him out to the lady's very high-ranked husband, hoping that the cuckolded man would complain to the school and get Marion expelled. It fails big time: not only the old man is more or less [[MyGirlIsASlut indifferent]], but when his and Marion's friend Jacques finds out, he '''[[TheReasonYouSuckSpeech explodes]]''' on Lind himself.]]
* Near the end of ''Anime/MagicalGirlLyricalNanohaReflection'', it's revealed that [[spoiler:Kyrie's ChildhoodFriend Iris has actually been pretending to be her friend since the day they met and was only using her as a pawn to get her revenge on Yuri.]]

* In the final part of ''[[JusticeLeagueOfAmerica Justice League]]'': ''ComicBook/TrinityWar'', [[spoiler:the Atom (Rhonda Pineda) who was first thought to be a sleeper agent for the JLA working on the Justice League, but was revealed to have put a small piece of Kryptonite in Superman's brain, poisoning him. She revealed that she was a sleeper agent from Earth 3.]] before this, [[spoiler:she]] was one actually quite friendly to everyone.
* ''ComicBook/LargoWinch'': Largo finds himself in a Turkish cell framed for a murder with a Swiss safecracker named Simon. When word gets out that he's the heir to an enormous fortune and company, the terrified higher-ups let him out, but the StateSec guy secretly has them shadowed to be murdered. This backfires on him, and with Simon and Largo now FireForgedFriends, they start looking for the person who had Largo framed in the first place. This leads to one of his company's [=CEOs=], who... orders Simon to pull a gun on Largo, before revealing that he'd set up the entire thing, counting on the two becoming friends, to get Largo exactly where he wanted. What the CEO ''hadn't'' counted on was that his hold on Simon was guaranteed by holding Simon's adoptive mother hostage, which made Simon confess as soon as they were out of Turkey. Then Largo found out that the CEO's goons had tortured her to death... The CEO's death at Simon's was neither pretty, soundless or quick.
* In ''ComicBook/TheSmurfs'' comic book story "The Jewel Smurfer", Ganelon is revealed to be this to the duke of Abelagot, having kidnapped the duke's son and held him hostage to extort a ransom from the duke. The Smurfs know about this and put on a ShowWithinAShow to expose Ganelon as a traitor.

[[folder:Films -- Animation]]
* Gothel in ''Disney/{{Tangled}}'' tried to make Rapunzel believe that Flynn was this, that he was only after the crown and never cared for her. She nearly succeeded, until [[spoiler:Rapunzel remembered her true heritage and realized that Gothel had kidnapped her and Flynn was going to be executed]].
* In ''Disney/{{Frozen}}'' Prince Hans eventually reveals that he simply wanted to get close to Anna [[spoiler:in order to marry into the royal family]]. After learning that [[spoiler:Anna is dying and can only be saved by true love]], he has this to say.
--> ''[[spoiler:"Oh Anna... if only there was someone out there who loved you.”]]''
* Lil Lightning the Welsh Corgi from ''Disney/OneHundredAndOneDalmatiansIIPatchsLondonAdventure'',: He informs Thunderbolt that his character is being killed off the show, when in fact, it's soon revealed to be a lie just to trick the German Shepard into getting out of the picture in order so Lightning can have the spotlight for himself having grown tired of being in Thunderbolt's shadow.
-->'''Lil Lightning''': ''[to a Thunderbolt Plush Toy]'' A whole new direction! What do you think of ''that'', Thunderbolt, old pal? Finally, I'll be able to step out of your shadow, you overrated, overacting ham! "''The Lil' Lightning Adventure Hour''". Has a nice ring, doesn't it? What do you think? ''(chuckles)''
** Then upon hearing about Thunderbolt still gaining fame while on a real heroic mission, Lil' Lightning then decides to join forces with him, along with the pup, obviously just to stop them from ''succeeding'' as to prevent Thunderbolt from reclaiming the spotlight. Once they reach the bad guys' hideout, Lightning persuades them to go for an open attack to rescue the puppies instead of a stealth plan, which of course, fails and gets Patch and Thunderbolt locked up in cages along with the other puppies. He even reveals to them his true nature and intentions before leaving them behind in their cages.
-->'''Thunderbolt''': ''[about getting hit in the head with a paint can by Cruella]'' That hurt. That ''really'' hurt!\\
'''Patch''': I ''knew'' you were faking it.\\
'''Lightning''': ''(suddenly, out of nowhere, he appears and chuckles)'' Oh, he's been ''faking'' it, all right.\\
'''Thunderbolt''': Lightning, little buddy.\\
'''Lightning''': ''(angrily in Thunder's face)'' I am NOT your "little buddy!" And YOU are no wonder dog! This kid trusted you, and look where it's got him.\\
'''Patch''': What's he mean?\\
'''Lightning''': He's been lying to you all day, kid. He doesn't care about you, or your family. He was just trying to get his name in the paper, and SAVE his job. Ask him!\\
'''Thunderbolt''': NO! Well, yeah, but - but...\\
'''Lightning''': (''mockingly'') "But - but - but." HEY, GENIUS! You're no hero! You're a '''''FRAUD!''''' And by the way, there ''never'' was a plan to recast you. I just had to get you out of the way. ''[grins evilly at him, then starts to head back toward the exit with a wicked chuckle and a devious look on his face]'' And now, I get to go take your place on the show! ''MY'' SHOW!\\
''([[EvilLaugh laughs evilly]], and exits, just as it is about to storm outside)''


[[folder:Films -- Live-Action]]
* In ''Film/TheAdventuresOfTartu'', it's PlayedForDrama and Averted. Terence admits to Marushuka (part of LaResistance) that he's a British spy sent to sabotage a German gas plant, but she becomes suspicious of him when his actions leads to the deaths of several underground members.

However, he allows himself to be instrumental in the biggest MindScrew the studio pulls on Truman in bringing his "father" back from the grave. He later leads the hunt to capture Truman once he starts escaping.
** Though there is a good scene when he clearly struggles with the lines that the producer is feeding him through his ear piece. He visibly chokes a little when he's instructed to reaffirm his best friend status and that he would never lie to him.
*** Though that could be just good acting.
** There are deleted scenes that indicate that Marlon/Louis does in fact feel guilty about what he's doing to Truman, and the (actual, real-life) actor said that the character has a drug addiction from the stress.
* ''Film/TenThingsIHateAboutYou''. Chastity, who is supposedly the best friend of the second leading lady, Bianca, not only goes out with her original date, Joey, but even rubs her face in it afterwards by revealing that Joey only took her out on a bet with his buddies in the first place.

** [[spoiler:Wormtail]] does this when he betrayed Harry's parents to Voldemort, even though they were his best friends - though he was more of a FairWeatherFriend who [[spoiler:sold out his buddies in order to save his own life]]. When his remaining friend [[spoiler:Sirius,]] chased him down after James and Lily's deaths, [[spoiler:Wormtail shouted that Sirius had been the one to sell out the Potters, caused an explosion that killed a dozen innocent people, and faked his death before escaping, pinning the murders of himself, the Potters, and all the other people on Sirius]].

* [[spoiler:Kij Porter]] in ''Literature/ABrothersPrice'', [[EvilAllAlong the worst kind]].
* [[spoiler:[=ForceFlow=], actually a pseudonym for the BigBad]] to Tash in ''Literature/GalaxyOfFear''. She wasn't the first one, either.

* ''Literature/ASongOfIceAndFire''
** [[spoiler:Ser Dontos]] acts like a friend and confidant to Sansa and promises to help her escape the Lannisters [[spoiler:to repay her for saving his life. In actuality he's working for Littlefinger and is willing to sell her out to whoever will pay him for it]].
** [[spoiler:Shae]] to [[spoiler:Tyrion]], she acts like she cares about him but she's really just a GoldDigger who's more than happy to accuse him of crimes he didn't commit for the promise of riches and status.
** One of the themes of Daenerys' storyline is the constant presence of these and her doubts to tell her real allies from those who seek to use her or will at some point betray her. The appendix section dedicated to her in ''Literature/ADanceWithDragons'' event lists "Her uncertain allies, false friends, and known enemies."
** Lancel Lannister, Falyse Stokeworth, the Kettleblack brothers and poor Sansa (again) should have run the second Cersei smiled at them in either a friendly or seductive fashion. Yup; just using you, suckers. Mind you, Cersei also gets suckered herself: Taena Merryweather and Aurane Waters basically suck up to her primarily to try taking her to the cleaners.
* The first ''Literature/NightHuntress'' book has a classmate cozying up to Cat, only to try to kidnap her for a white slavery ring. Turned out she did this to a lot of girls.
* Poor [[HorribleJudgeOfCharacter Neru]] from ''[[Literature/{{REEL}} REAL]]'' doesn't have much luck when it comes to friends: he manages to befriend his longtime online crush [[AmbiguousGender Likaï]], only to get his heart broken [[spoiler: when Likaï steals his account to enter the Future Tournament in his place.]] When Neru manages to contact his three teammates to ask them for help, they all turn their back on him: as it turns out, they just hung out with him in TheMetaverse for the bonus points and glory that they got thanks to his talent for video games.
* In ''Literature/{{Worm}}'', Taylor tries to become this to the supervillain gang the Undersiders, but finds herself BecomingTheMask.

[[folder:Live-Action TV]]
* In ''Series/{{Oz}}'' Schillinger arranges for [[DepravedBisexual Chris Keller]] to meet [[ButtMonkey Tobias Beecher]], Schillinger's former sex slave, with the intent of gaining his trust and seducing him. A mutual attraction instantly forms between them, and the two eventually exchange confessions of love. Unfortunately for Beecher he finds out that the man he fell in love with was working with his arch enemy all along (and informs him that he never loved him right before breaking Beecher's arms and legs). Keller clearly enjoys the beating, but is briefly seen experiencing a moment of regret when he returns to his empty cell and eventually realizes that he has fallen in love with Beecher.
** Ryan O'Reily and pretty much '''everyone''' he ever purports to be friends with, but probably the biggest example is the way he ingratiates himself with Nino Schibetta while secretly slipping ground glass into the man's food.
* Morgana, with Uther and Arthur, since the beginning of ''Series/{{Merlin}}'' season 3.
* Series/{{Columbo}} ''admits'' to doing this (once) at the end of one of the Creator/{{ABC}} TV movies.
* Nina Myers on ''Series/TwentyFour'' is the show's biggest example of this, being Jack Bauer's primary confidant at CTU in season 1 until she [[spoiler:killed his wife while trying to escape after being outed as a mole working for the bad guys]]. She would then go on to become a recurring villain in seasons 2 and 3.
* In ''Series/RobinHood'', Marian cultivates a "friendship" of sorts with Guy of Gisborne so that she can pass on information to Robin. She even goes so far as to pull off a perfectly executed DecoyDamsel ploy, which Guy falls for hook, line and sinker. Guy was something of a FalseFriend himself considering he seems more than ready to have Marian punished if she disobeys him, and when he learns that she's in love with RobinHood, he [[spoiler:stabs her to death]].
* [[spoiler:HG]] from ''Series/{{Warehouse 13}}'' does this using the other agents to get an artifact so [[spoiler:she]] could destroy the world though she does somewhat [[BecomingTheMask become the mask]], getting talked down from doing this when her friend tells her to shoot her instead of being a coward and killing her with the rest of the world.
--> '''Myka:''' If I am wrong, then kill me. Do it! Kill me now! I mean, we're all gonna die anyway right, so what's the difference? So shoot me! Shoot me now. Kill me. But not like this. Not like a coward. I want you to look me in the eyes and. Take. My. Life.
* In ''Series/KamenRiderFourze'', [[spoiler:Ryusei/Kamen Rider Meteor]] at first[[note]]After Episode 31 he becomes a [[TrueCompanions true companion though]][[/note]].
** JK establishes himself as a "friend" who takes advantage of others, and isn't ashamed to admit this. Gentarou accepts him anyway, and makes AnAesop about how you have to accept a person's worse sides too if you want to befriend them. JK ends up getting better.
* ''Series/GameOfThrones'':
** Ramsay Snow, aka [[spoiler:"The Boy"]], pretends to be [[spoiler:Theon Greyjoy's]] only friend and ally. He helps the latter escape his torture, kills several of their pursuers who are trying to gangrape him...only to lead him back to the torture chamber. Why did he do all of this? Because it was ''fun''. He also razed Winterfell to the ground on his father's orders, despite supposedly being there to save it.
** Locke joins the Night's Watch and pretends to befriend Jon Snow as part of a plan to kill or capture Jon and find Jon's half-brothers Bran and Rickon and do the same to them, fooling Jon into genuinely believing that he is a new Night's Watch recruit. As Locke dies of a broken neck, courtesy of Bran warged into Hodor, his plan to betray Jon and what he planned to do to Jon's brothers is never discovered because his true intentions are never revealed. Locke's dead body is then later ceremonially burned, with Jon, Grenn, Edd and the others all believing that he had died as a loyal brother of the Night's Watch, at the hands of the mutineers.
* An episode of ''Series/{{Monk}}'' sees Andy Richter play a man who pretends to befriend Monk in order to obtain a piece of evidence Monk unknowingly has that could implicate him. Even after discovering that he's a criminal, in the end Monk still considers him a better friend to him than many people he's met in the past.
* In ''Series/{{Roots|1977}}'' and [[Series/Roots2016 its 2016 remake]], Missy is seemingly established as Kizzy’s closest friend from childhood. She even goes as far as protecting Kizzy from racist relatives and teaching her how to read. However, [[spoiler:when Noah was revealed to be carrying papers forged by Kizzy]], she doesn’t bother protecting Kizzy [[spoiler:from being sold to another slave owner. She later has the ''gall'' to feel betrayed for Kizzy helping out some abolitionists]].
* In ''Series/HowToGetAwayWithMurder'', it's eventually revealed that on the day of her death, Lila [[spoiler:admitted that she only hung out with Rebecca because she felt sorry for her and because she wanted a distraction from her stressful life. She ends their friendship by stating that she's too good for Rebecca, a "[[KickTheDog trashed-out druggie whore]]", to hang out with.]]

* "I Was Only Kidding" by Music/WeirdAlYankovic is this.
* "[[http://www.youtube.com/watch?v=WdDoiT7NZKo How Could You Believe Me When I Said I Loved You When You Know I've Been A Liar All My Life?]]" Yes, that's actually the title.
* ''[[http://www.youtube.com/watch?v=yHgohkVWvng I know I'm not so perfect, I know I'm not so cool...but don't try to lie to me, 'cause I know the truth...]]''
* "Your Enemy Cannot Harm You (But Watch Your Close Friend)," originally by Blind Willie Davis, is about how your enemies don't know you well enough to hurt you as deeply as your "friends."
* An early [[Music/JoanJett Joan Jett and the Blackhearts]] song, "Fake Friends" is pretty much about this trope, and why it is better to cut ties with those who are only friendly to you when it is convenient for them.
-->''You got nothin' to lose, you don't lose when you lose fake friends!''

* Podcast/DiceFunk: [[spoiler:Jayne hates Rinaldo so much that she tries to sell him into slavery.]]

[[folder:Professional Wrestling]]
* Wrestling/KevinSteen and [[Wrestling/SamiZayn El Generico]] used to be friends, but not quite as close of friends as Generico thought they were, and Steen slowly but surely drifted apart from him until, well...Steen was this trope.
* After the Bro-mans caused the Wrestling/TheBeautifulPeople's second Wrestling/{{TNA}} disbanding when Robbie got Wrestling/VelvetSky fired, Wrestling/AngelinaLove, who had tried to rejoin the group early into her fourth TNA run, was happy to see Sky go.
* After breaking up Wrestling/TheShield, Wrestling/SethRollins ''claims'' he was this to Wrestling/DeanAmbrose and Wrestling/RomanReigns. Though he tends to slip and show that he may have cared about them more than he'd like to admit.

* ''Theatre/CyranoDeBergerac'': Given the shallow Parisian society at TheCavalierYears, this play is full of them:
** De Guiche [[GirlPosse pays a fine court of obsequious noblemen]], but the nobles really distrust and despise him because he is a Gascon. They only bow to him because he is successful.
-->'''Second Marquis''': Faugh!. . .Another Gascon! \\
'''First Marquis''': Ay, but the cold, supple Gascon—that is the stuff success is made of! \\
Believe me, we had best make our bow to him.
** The poets who frequent Raguenaus company claim to love Raguenau’s poetry, but they only want to leech him off.
** Cyrano defies this trope with all his will, as lampshaded in Act II Scene VII:
--> '''People''' ''(crowding round Cyrano):''
--> My friend!. . .my friend. . .
--> '''Cyrano:''' Meseems that yesterday
--> I had not all these friends!
--> '''Le Bret''' ''(delighted):'' Success!
--> '''A young Marquis''' ''(hurrying up with his hands held out):'' My friend,
--> Didst thou but know. . .
--> '''Cyrano:''' Thou!. . .Marry!. . .thou!. . .Pray when
--> Did we herd swine together, you and I!
* Iago of [[Creator/WilliamShakespeare Shakespeare's]] Theatre/{{Othello}}.

[[folder:Video Games]]
* There's an odd version of this in the ''Franchise/AceAttorney'' series. Dahlia Hawthorne tricks Phoenix into thinking she's in love with him, just so she can get a piece of evidence back that incriminates her for a previous murder. She tries to kill him when it doesn't work. It's subverted when Dahlia has her sister impersonate her for a while, and her sister actually does fall in love with Phoenix.
** [[spoiler:Kristoph Gavin became Phoenix's "friend" only to closely monitor his activities after Kristoph got him disbarred, and ends up framing him for a murder. Phoenix was aware of this, however.]]
* After dominating a player in ''VideoGame/TeamFortress2'', one of the Spy's {{Bond One Liner}}s is "I never really was on your side."
* A variation occurs in Specter's ending in ''VideoGame/TwistedMetalBlack''; [[spoiler:the man of her dreams has been forced to marry her by way of some brain surgery,]] but he's still able to tell her "I... will... ''never'' ...love ...you."
* The Boss in ''VideoGame/MetalGearSolid3SnakeEater'', before defecting, was Snake's mentor and one of his closest friends. She celebrates her FaceHeelTurn by beating him up and stealing his rescued hostage.
** [[spoiler:Subverted ''and'' played straight, however, as The Boss was really a FakeDefector sent in by the U.S. government to play the FalseFriend to BigBad Colonel Volgin. A devastated Snake only learns the truth after he's completed his mission to kill her.]]
* In ''VideoGame/Uncharted2AmongThieves'', Harry Flynn did this to Nathan Drake at the end of the Museum mission, causing poor Drake to rot in prison for 3 months.
* ''VisualNovel/MagicalDiary'': [[spoiler:Damien.]] That ''bastard''.
** If you get his good ending, it turns into BecomingTheMask... maybe. If you believe ''anything'' he says by that point!
*** If you've ground White magic enough to have gotten the spell Empathy, you can use it on him when you next talk to him. [[spoiler:He's telling the truth about how he feels now.]]
* In ''VideoGame/DragonAgeII'', it's possible for Hawke to do this to Fenris when he finally confronts his former master Danarius by handing Fenris back to him. This will devastate him so much that he'll simply submit without a fight. However, this act is considered a MoralEventHorizon by the other companions save for Anders, who hates Fenris.
* ''VideoGame/{{Touhou}}: Mystic Square'' features the [[PlayingWithFire fire]] and [[AnIcePerson ice]] magicians [[RedOniBlueOni Yuki and Mai]] as a DualBoss. If you defeat Mai first, Yuki will be furious and [[TurnsRed crank up the heat]]. But if you defeat Yuki first, Mai will smugly declare that her comrade was nothing more than "dead weight" dragging her down (though ironically Mai's regarded as the easier of the two). Mai's {{leitmotif}} is appropriately named "Treacherous Maiden ~ Judas Kiss."
* ''VisualNovel/HatofulBoyfriend'' sequel ''Holiday Star'' makes it clear this was the case for [[spoiler:Hitori Uzune and the original Nanaki Kazuaki, a quail whose clinical depression was exploited by Hitori to double-cross him in a suicide pact and steal his identity. The betrayal caused Nanaki's spirit to become an EldritchAbomination hell-bent on [[AssimilationPlot eternal companionship]].]]
* Upon his introduction in ''VideoGame/{{Mega Man 7}}'' Bass presented himself as a possible friend and ally to Mega Man. When he was hurt fighting Shade Man, Mega Man allowed him to go to Doctor Light to get repaired. Once all the Robot Masters are defeated he discovered that Bass betrayed him, wrecked the lab, stole his upgrades, and hurt Doctor Light. Wily then brags about how Bass was his creation to get closed to Mega Man and how he was going to use his own upgrades on Bass to destroy him. Needless to say, Mega Man was pissed and probably one of the reasons why he was willing to kill Wily at the end of the game.
* [[spoiler:Ellen to Viola]] in ''VideoGame/TheWitchsHouse''. [[spoiler:Ellen tricked Viola into sympathizing with her by telling her about her illness and the way her parents neglected her. Ellen just wanted to be "friends" with Viola because a bond of genuine trust was required for the demonic spell which would allow Ellen to pull a GrandTheftMe on Viola to work.]]

* ''Webcomic/MegaTokyo''. Miho did this to Piro some time before the start of the series.
* ''Webcomic/TheDreamlandChronicles'': [[http://www.thedreamlandchronicles.com/the-dreamland-chronicles/page-690/ Here]].
* In ''Webcomic/TheOrderOfTheStick'', Nale drives Elan to the DespairEventHorizon by telling him that Haley is this trope, taking advantage of [[NotWhatItLooksLike incriminating evidence]] and Haley's [[TheUnintelligible inability to defend herself]] to [[EvilGloating gloat]] about Haley's supposed betrayal of Elan's friends and Elan's stupidity in not seeing that she was EvilAllAlong. Elan is [[spoiler:briefly]] convinced and goes into a [[UnstoppableRage murderous fury]], telling Haley that he hates her, before Haley finally manages to [[CannotSpitItOut spit it out]].
** Nale also uses a suggestion spell to make Elan angrier, hence the uncharacteristic murderous fury.
* In ''Webcomic/GirlGenius'', Tarvek and Gil's childhood friendship ''was'' real. Sadly, circumstances separated them and they both became convinced that the other was a FalseFriend due to some more unfortunate circumstances. They are currently FireForgedFriends / VitriolicBestBuds.
* Happens quite a bit in the GambitPileup that is ''{{Webcomic/Erfworld}}''. Since Erfworld also features quite a few {{PunnyName}}s from earth, the two untrustworthy allies of one side are actually called Frenemy and [[TheQuisling Quisling]].
* ''Webcomic/TowerOfGod'' has several people like this: [[spoiler:Ho, Nia, and most notably Rachel. Later, Apple, Koon's hacker in the second season, turns out to be a FUG agent.]]

[[folder:Web Original]]
* In ''Roleplay/TheGamersAlliance'', [[ManipulativeBastard Ferron]] befriends [[LoveableRogue Refan]] during the Great War but does so only for two reasons: to avenge his lover who died by Refan's hand and to use Refan to get rid of TheDragon who had also wronged him (hoping that the two weaken each other enough in battle so that he can finish both of them off).
* [[spoiler: Felix]] in the 12th season of ''Machinima/RedVsBlue''. It turns out that [[spoiler: he'd been working with Locus all along, and was hired to wipe out the entire population of Chorus]].
* [[spoiler: Hanson]] in ''WebVideo/EndTimes'' pulls a major one of these.
-->[[spoiler:'''Charlie:''' You needed my help!]]\\
[[spoiler:'''Hanson:''' Or else I never would have been here.]]
* ''WebAnimation/{{RWBY}}'': [[TheDarkChick Emerald Sustrai]] seems friendly and chatty in her conversation with the eponymous heroines in "Round One", but the moment they part ways, Emerald makes very clear to Mercury how much she really despises them and finds their positive NiceGirl attitudes annoying. [[spoiler:She's the one responsible for framing Yang and tricking Pyrrha into killing Penny.]]

[[folder:Western Animation]]
* In ''Disney/{{Hercules}}'' the BigBad Hades is unable to defeat his enemy Hercules because he is unaware of his weakness. So he instructs Megara to get close to Hercules and they both end up falling in love. However, before she can tell Hercules the truth Hades ends up telling Hercules about how Meg was working for him all along in the most [[KickTheDog cruel manner possible]].
* Plankton in ''WesternAnimation/SpongeBobSquarepants'''s "F.U.N." episode.
** "Porous Pockets" involves a large crowd of people leeching off of Spongebob after he earns a small fortune. Once it dries up, they instantly abandon him.
* Terra in ''WesternAnimation/TeenTitans'', though [[BrokenBird sympathetically so]].
** She's much, ''much'' nastier in [[ComicBook/TeenTitans the comics]], as Terra was not a lost girl brainwashed by Slade. She was a pure psychopath that Slade was almost ''scared of'' (You read that right). Worse is that she was also Slade's [[{{Squick}} underage girlfriend]]. What makes it especially hilarious is that at no point in the lead-up of the comic arc does she ever really pretend that she doesn't dislike nearly everyone on the team nor isn't lying constantly to them, so the Titans, in retrospect, were TooDumbToLive.
** Malchior is this to Raven in the "Spellbound" episode.
** And Blackfire, Starfire's sister, who pretended to care for her sister while framing her for the crimes she committed so Starfire would get taken to jail instead. Starfire eventually finds out the truth and engages her in battle which leads to Blackfire rightfully getting captured by the police.
* Done to [[TheSimpsons Bart Simpson by Jessica Lovejoy]]. She pretends to like and befriend him, only so she can act as bad as she wants, knowing that if she gets caught, she can always blame Bart and let him take the fall. If not for Lisa, it would have worked.
* A HeelFaceTurn example occurs in ''WesternAnimation/AvatarTheLastAirbender''. In "The Boiling Rock", [[spoiler:Azula gets this after Mai and Ty Lee turn their backs on her]]. It is possible that [[spoiler:they were never friends with her in the first place, since they were scared of her. It's also possible that she just went too far this time and they weren't willing to put up with her any longer.]]
* Brought up once in the original ''WesternAnimation/ThunderCats''. "Better an honest enemy than a false friend."
* In ''WesternAnimation/ThunderCats2011'', [[spoiler:Pumyra]].
* Tirek plays this role to Discord in the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode ''[[Recap/MyLittlePonyFriendshipIsMagicS4E26TwilightsKingdomPart2 Twilight's Kingdom Part 2]]''.
** Trixie started off as this in ''[[Recap/MyLittlePonyFriendshipIsMagicS6E6NoSecondPrances No Second Prances]]'', where she pretended to be Starlight's friend just to get back at Twilight. But as the episode went on, Trixie started to consider Starlight a friend.
* In one episode of ''WesternAnimation/{{Recess}}'' Gretchen befriends a little girl named Becky while getting ready for the school science fair, only to find out that Becky was pretending to be Gretchen's friend so she can steal her project.
* In an episode of the animated adaptation to ''Literature/TheBerenstainBears'' the new kid, Ferdie, befriends the popular girl, Queenie, not knowing that she's just using him to get the homework answers. It isn't until Ferdie sees Queenie laughing at him after he took a football to the gut that he realizes the truth. Queenie eventually apologizes to Ferdie, both for laughing at him and pretending to be his friend.
* [[BigBad Bill Cipher]] in ''WesternAnimation/GravityFalls'' was this to [[BigGood The Author]] (aka [[spoiler:Stanford "Ford" Pines]]). The Journal's original entry on Bill describes him in glowing terms as the nicest, most trustworthy being in the universe. After he discovers Bill's true nature, he crosses out the whole entry and describes him as the most dangerous and evil being in the universe, to never be summoned at any cost.
* In the ''WesternAnimation/SamuraiJack'' episode "Jack and the Warrior Woman", [[TheHero Jack]] meets and befriends [[ActionGirl Ikra]], who claims to have a similar [[DarkAndTroubledPast tragic backstory]] like he does, and joins him on a quest to find a magic jewel so that Jack could [[TimeTravel return home]]... only for Ikra to betray him by smashing the jewel, and then reveals that "she" was actually [[ArchEnemy Aku]] [[VoluntaryShapeshifting in disguise]] all along; much to Jack's shock, rage, and sorrow.
* In the ''WesternAnimation/JackieChanAdventures'' episode "Tale of the Demon Tail", [[MonsterOfTheWeek Hsi Wu]] the [[WingedHumanoid Sky Demon]] invoked this trope as part of a gambit; [[VoluntaryShapeshifting he changes into the form of]] [[HumanDisguise a human boy named "Seymour"]] and befriends [[KidSidekick Jade Chan]], gaining her trust so that [[MustBeInvited he can be allowed entrance into Uncle's shop]], [[ItMakesSenseInContext and then retrieve his lost severed tail that they seized from him]]. Jade, who's a lonely kid at her school, is very happy to make a new friend, and she even grows a crush on him... too bad that "Seymour" has to inevitably reveal his true identity and [[FauxAffablyEvil not-so-friendly intentions]] in the climax.
* In ''WesternAnimation/SouthPark'', Butters considers Cartman to be a friend that he can hang out and do fun stuff with. Cartman takes advantage of this and frequently manipulates Butters into being a pawn for his latest scheme, uses him as a scapegoat for to pin his actions on, or even outright bullies and embarrasses him at school.
