Our hero is in a duel with a crafty {{Shapeshifter}} villain. It looks like the shapeshifter is going to lose, until he busts out the most underhanded trick of all -- suddenly impersonating one of the hero's loved ones or TrueCompanions, trying to cause him to lose his will to fight.

Usually, the hero ends up struggling to find the willpower to continue beating up someone who looks just like his mom/girlfriend/little sister. Bonus points if the form the shape shifter takes on is that of a dead little sister, for extra guilt.

Also covers [[CloningBlues clones]] and other doppelgangers who [[ThisWasHisTrueForm suddenly reveal]] that they happen to resemble the hero's mom/girlfriend/dead little sister/[[DeathByNewberyMedal Dead Pet]]/whatever.

If the protagonist is an AntiHero, there's the possibility that they won't care at all about what face they are kicking in as long as they know whose face it ''actually'' is - the bad guy's.

There's also an increasingly common [[WrongGenreSavvy subversion]]: because of personal issues between the hero and the character the shape shifter takes the form of, the hero actually becomes ''more'' willing to attack. Also, all the shape shifter may do is succeed in pushing the RelativeButton.

[[folder: Anime and Manga ]]
* ''Anime/InuYashaTheMovieFireOnTheMysticIsland'': Inuyasha manages to get the better of [[CloningBlues the Kikyo clone]] during their fight, but can't bring himself to finish her off; the real Kikyo proceeds to show up and kill the clone herself before berating Inuyasha for letting himself be tricked by the fake.
* Envy of ''Manga/FullmetalAlchemist'' positively ''loves'' this. In a pivotal moment, [[NoBiologicalSex it]] uses this to [[spoiler:kill Hughes by transforming into a replica of the wife he adores, which makes poor old Hughes hesitate just long enough to get shot]]. And given Envy's regenerative powers, it wasn't really necessary either, it was just ForTheEvulz.
** In one encounter, Envy is about to be stabbed by [[spoiler:Ling Yao, so it alters its appearance to that of Lan Fan, who has just been driven away to get medical attention for a severe injury she attained while protecting Ling, causing him to freeze up and enable Gluttony to swallow him. ''Brotherhood'' takes this a step further than the manga, having Envy appear as Lan Fan in her current vulnerable state; bandaged and without her left arm, her mask gone revealing a hurt expression.]]
*** Which makes no sense whatsoever, as Lan Fan was gone by the time Envy showed up, and it had only ever seen her with her mask on. And, unless it had met up with Wrath before going after Gluttony, it had no way of knowing that [[spoiler:she had lost an arm, especially as Brotherhood skipped over Envy's role in it and Gluttony's fight against Ling and Lan Fan]].
** In Envy's fight against [[spoiler:Mustang]] near the end of the manga: [[spoiler:Mustang finally gets to confront Envy about who murdered Hughes. Envy responds by shape-shifting into Hughes' wife, and laughing at how easily he was tricked. Mustang is not amused. During the fight, they end up in some narrow corridors, and Envy take the opportunity to appear in Hughes's form. It does make Mustang momentarily flinch, but unfortunately for Envy, the whole reason Mustang was after it was because it had murdered Hughes, and the reminder only served to piss him off even '''more'''. It was a CurbstompBattle to begin with, and that stunt only made things ''worse'' for Envy.]]
** Hilariously, Envy is something of a {{Hypocrite}} regarding its use of this trope, referring to it as a cheap trick and taunting opponents when they fall for it, but then turns around and tries to invoke WhatTheHellHero on the ones that ''don't''.
--->'''Envy'''[[spoiler: (To Mustang, while disguised as Hughes)]]: What's the matter with you!? You didn't even hesitate to incinerate your best friend!?
** During his climactic fight with Ed at the end of [[Anime/FullmetalAlchemist the 2003 anime version]], Envy cycles through the forms of everyone who's been either hurt or killed as result of Ed's actions. He tries to psyche him out by turning into Dr. Marcoh, his mom/[[spoiler:Sloth]], Hughes, and Mustang (which only makes Ed attack him ''harder''). For the most part it only makes Ed angrier (pointing out he [[spoiler:killed Sloth when ''she'' tried it]]), and he even goads Envy into showing his original (human) form. [[spoiler:Let's just say it was one [[LongLostSibling family reunion]] Ed was ''not'' expecting, and the shock allows Envy to line up a fatal blow.]]
* In ''Manga/OnePiece'', Mr. 2 Bon Clay uses this as a desperation attack against Sanji. Sanji heartlessly beats up all of the doppelgangers of the male Straw Hat pirates, and Bon Clay is about to give up till he carelessly switches to Nami, [[WouldntHitAGirl which paralyzes Sanji with lust]]. Bon Clay comments, "It can't really be that easy, can it?" He toggles his face-switching power on and off to cure his disbelief, and then uses the form of Nami against Sanji because Nami looks just too cute for him to hit. ''Until'' Bon Clay learns he can't use his Okama Kenpo properly because he's not used to her physique.
* In ''SaintSeiya'' Lyumnades Kaza did this thrice on-screen (plus a couple off-screen times). First in a battle against Cygnus Hyoga, taking the form of Aquarius. Then against Pegasus. Then in battle against Shun by transforming into his brother; it didn't work at first. He did it again when Shun was getting the upper hand, and it made Shun doubt enough for Kaza to beat him. Finally he did it against Shun's brother Ikki by transforming into Shun. But as Ikki was a GenreSavvy AntiHero, it didn't work.
** Better yet, Ikki beats Kaza by transforming into ''him'', and Kaza whines that he's unable to hit his own image. This shows how cowardly he is,because this wouldn't have worked on any of the heroes.
* In ''Manga/{{Bleach}}'', the hollow Grand Fisher has a lure on his head. By reading his target's psyche, he can transform that lure into the person the target cares about the most. He impersonates Ichigo's dead mother early on in the series.
** [[spoiler:Later on, an Arrancar also impersonates Kaien Shiba, Rukia's mentor, to great effect. This particular one happened to be the 9th Espada, Aaroniero Arruruerie]]. In both cases, the impersonator had eaten the impersonate-ee.
* The ''SorcererHunters'' manga had a variation: We eventually learn that [[BodySurf Body Surfing]] demon Almond Rassel had been trapped in the body of Apricot, the MissingMom of Carrot and Marron. In the final battle, Almond has to fight Onion Glace (Carrot's [[CrouchingMoronHiddenBadass Crouching Moron Hidden]] RetiredBadass father), and plays his current body for all it's worth. Onion has no problem attacking [[DoppelgangerSpin Almond's clones]], but can't bring himself to attack the real body of his wife. His solution: grab on to Almond and [[TakingYouWithMe stab them both]] with his [[PrecisionGuidedBoomerang boomeranging]] [[{{BFS}} Big Freaking Axe]], which he aimed at ''himself''.
* Parodied in ''RanmaOneHalf'', when the Cat Demon possessed [[spoiler: Genma]], thinking that Ranma wouldn't attack [[spoiler: him]]. Ranma's response: IT'S EXORCISM TIME!
** To explain further, it really didn't help that [[spoiler:Genma forced Ramna to fight [[WhyDidItHaveToBeSnakes a giant cat]] since, no matter how weak a demon it was, Ranma is utterly ''terrified'' of cats. Right before booting his son towards said terror, Genma says that it's a martial artist's job to defeat demons, no matter what. Ranma repeats that right before beating up his old man.]]
* ''DanceInTheVampireBund'': One of the assassins sent after Akira in vol 4 pulled this. [[spoiler:It worked perfectly when he took the form of Graham, a colleague whom Akira killed under as yet unknown circumstances, but then she(?) twisted the knife and tried to extract information by taking the form of Mina. Big. Mistake.]]
* In ''ProjectARMS'', one of the cyborgs that Hayato fights tries to trick him by impersonating Ryo. In this case, it was done to trick Hayato and not guilt him. After Hayato figures out the truth and impales him, the cyborg takes the form of Hayato's dead mother before dying.
* [[BigBad Dougan]] in the ''{{Saiyuki}}'' Requiem Movie absolutely adores doing this; so much so that it becomes pretty much the premise of the entire movie. For Sanzo he changes into his mentor Koumyou as well as his teammates Sha Gojyo, and Son Goku. For Goku he changes into Genjo Sanzo. For Sha Gojyo he changes into Hakkai and induces stabby death onto him. And for Cho Hakkai he shapeshifts into both his dear [[http://www.youtube.com/watch?v=wNlWH1DtjRM sister/lover Kanan]] as well as his [[http://www.youtube.com/watch?v=1qp5jvDFQuw&feature=related friend Goku]].
** Various enemies try this in the Saiyuki manga as well. Usually to not much effect since the main characters can be positively gleeful about beating up doppelgangers of one another. On one memorable occasion they start beating up a doppelganger of Gojyo ''before'' realising it's not him (they did have reason to be angry with him at the time, though).
* ''Manga/FairyTail'': A variation of this is used by [[DishingOutDirt Monsieur Sol]] against [[BoisterousBruiser Elfman]] in the anime. He used his earth powers to create clones of his dead little sister. Borders with horror.
* ''NabariNoOu'': PlayedForLaughs in an omake where Tobari is unable to attack Fuuma when he takes Raimei and Miharu's forms. [[CrowningMomentOfFunny It fails when Fuuma takes Kouichi's form, though]].
* Variation in ''LightNovel/ACertainMagicalIndex'': [[NoNameGiven The girl in the dress]] can make people feel in their hearts that she is someone else, usually a loved one. Shiage Hamazura is unable to attack her when she makes him feel that she is Rikou Takitsubo, his girlfriend. The girl in the dress notes that some people will attack her ''harder'' if she tries this, because by perceiving her as a loved one, they believe they have been betrayed and become enraged. When faced against Accelerator, she retreats, reasoning that the AxCrazy psycho would react that way.
** This happens twice in the series' New Testament Vol 6:
*** Shizuri Mugino gets confronted by what seems to be Frenda Seivelun, who she had killed back when she was a bad guy and had been feeling guilty about ever since. "Frenda" orders her to atone for her sin by dying, then moves to attack her. At the last second, Mugino snaps out of it and fights back. Her hunch that it wasn't actually Frenda was right, it was a shapeshifting man who wanted to play on Mugino's guilt to weaken and then kill her.
*** Kakine Teitoku makes an army with his Dark Matter that looks, sounds, and acts like the Misaka Sisters and turns them on Accelerator. Accelerator, who had sworn to protect the Misaka Sisters and is eternally guilty about killing some back when he was a bad guy, falls into despair and almost lets them kill him. Mugino steps in and saves him. Drawing on her experience with the fake Frenda, she reminds Accelerator that they're just Kakine's puppets, not the actual Misaka Sisters, which restores his will to fight.
* Variation in ''GetterRobo Armageddon,'' where an Invader (who can infect humans and [[TheVirus turn them into more Invaders]]) attempt to guilt-trip the Shin Getter team by coating itself in the reformed bodies of [[BodyHorror not-quite-dead]] victims. This successfully prevents the Shin Getter team from attacking it - but its not quite so useful defending against [[AxCrazy Ryoma and the Black Getter]], who simply do not give a fuck.
* In ''Manga/HeavensLostProperty'', Chaos shifts in and out of the forms of Nymph's friends while beating her up and berating her. Nymph objectively knows that the being before her is Chaos and not her friends, but it doesn't matter, she's too traumatized to fight back. When Ikaros tries to attack Chaos, she shifts into Tomoki, and Ikaros is fooled even though she saw her transform before her eyes and obeys Chaos until Astraea intervenes. Later, when Ikaros is about to throw Chaos into the sea, Chaos turns into Tomoki again and begs her to stop, but this time, Ikaros points out that Tomoki is an excellent swimmer and wouldn't be worried about the sea.

[[folder: Comic Books ]]
* In NeilGaiman's ''ComicBook/TheSandman'', Loki attempts to pull this on the second Corinthian, cycling through a series of forms (starting with Dream, followed by a dragon, the Corinthian himself[[labelnote:*]]Corinthian's reaction: "Oh, please. Credit me with at least the wit to know which one of us I am."[[/labelnote]], the toddler who the Corinthian is supposed to be rescuing, a flame, and finally his true form) trying to find one the Corinthian ''won't'' strangle. The Corinthian, needless to say, is not impressed.
* When the [[ComicBook/TeenTitans Titans]] and the [[ComicBook/JusticeLeagueOfAmerica Justice League]] collided, the Titan Mirage went up against the MartianManhunter by posing as his dead wife.
* ''ComicBook/TheElementals'' by Bill Willingham did an elaborate variant which [[TheReveal revealed]] that a {{Shapeshifter}} that the Elementals had fought before had, over the course of a StoryArc gotten one of the team, Morningstar, to fall in love with him/her.
* A rare heroic example comes from ''ComicBook/WildCATS''. When team was fighting Lord Entropy, an impossibly powerful madman who wanted revenge against Lord Emp for killing his wife, Voodo used her illusion to look like her. Entropy was so confused that Emp ha enough time to prepare to wipe the floor with him.
* Another heroic example in ''Comicbook/{{Runaways}}'', when Xavin shifts into the late wife of a [[BalefulPolymorph man-turned-monster]] to talk him down from his destructive rampage.
* During ''ComicBook/SecretInvasion'', several Skrulls shapeshift into corpses and claim to be victims of [[Comicbook/CivilWar the Stamford Incident]]. Although it works on Penance at first, [[{{Wangst}} he remembers the faces of everyone who really perished]] and attacks.
* ''[[ComicBook/{{X-Men}} Astonishing X-Men]]'': Subverted (and inverted?) in JossWhedon's run. Kitty Pryde is confronted with Colossus (the genuine article); not believing it's really Colossus, back from the dead, she tells him that if he's a robot or a clone, she'll understand, but if he's a shapeshifter or illusionist, he's in for a new meaning of pain.
* In ''{{Nodwick}}'', the party encounters an undead monstrosity that uses magic to make whoever is looking at it see a dead mentor or parental figure they would trust implicitly (Nodwick sees his former guildmaster, Arthax sees the man who trained him to be a wizard, Piffany sees the head priest who raised her, and Rowan sees her adventurer father). All of them can only stare dead-eyed at it and mumble "I thought you were dead". Fortunately, while the magic also affected [[OurDragonsAreDifferent Orville]], his species of dragon instinctively try to [[SelfMadeOrphan fight and kill their own parents for dominance]]...
* [[Franchise/GreenLantern Red Lantern]] Rankorr used his power ring to make constructs resembling Abysmus' victims, paralyzing him with guilt and allowing Atrocitus to defeat him.
* Early on in ''ComicBook/AvengersTheInitiative'', Trauma had difficulty controlling his fear-based transformation powers, causing him to freak out Cloud 9 by transforming into a zombified version of MVP, who was killed while protecting Cloud 9 from an errant rifle blast. When Hank Pym tried to intervene, Trauma transformed into an extremely battered version of Janet Van Dyne, reminding Hank of his [[NeverLiveItDown domestic abuse incident]], which sent poor Hank scrambling for his anti-anxiety meds.
* An inadvertent version occurred when the Runaways visited ComicBook/AvengersAcademy. Reptil tried to entertain the guests by showing off his dinosaur-transformation abilities. He made the mistake of turning into a deinonychus in front of Klara who, up to that point, still believed that she was responsible for Old Lace's apparent death, resulting in Karolina having to rush over and calm the poor girl down before her powers started kicking in.

[[folder: Fan Fiction ]]
* In the ''KingdomHearts'' fanfic, ''A Match made in Hell'', the BigBad tried this separately on Sora, Roxas, and Pete, transforming into everyone they knew, including Organization XIII.
* In the ''FanFic/PonyPOVSeries'', [[spoiler: when Twilight [[JourneyToTheCenterOfTheMind travels into Trixie's mind]] in order to undo her discording, [[EnemyWithin Loneliness]] creates an illusion of a mental hospital and takes the form of a doctor, and tries to convince Twilight that she killed Trixie and has been institutionalized. Fortunately, Twilight notices the [[AGlitchInTheMatrix mistakes in the illusion]] and breaks free.]]
* In the ''[[Fanfic/PonyPOVSeriesChaosVerse Chaos Verse]]'' (an official spin-off of the ''POV Series''), the BigBad [[spoiler: Nightmare Phobia]] infiltrates Fluttershy's dreams and takes the form of her friends to try and [[DrivenToSuicide drive her to suicide]]. [[spoiler: It almost works, but thankfully, Fluttercruel is able to intervene and save her.]]
* In ''FanFic/GettingBackOnYourHooves'': [[BigBad Checker]] does this to most of the Mane Six during the FinalBattle, taking the form of their loved ones and giving them each a BreakingLecture based around their personal faults and saying those faults have in some way harmed said loved ones. Special mention goes to Rainbow Dash's, which involves her how she handled Discord's SadisticChoice, something she feels genuine guilt for.
[[/folder]]

[[folder:Film]]
* In the ''[[Film/TheSpiderwickChronicles Spiderwick]]'' books and FilmOfTheBook, [[spoiler:[[BigBad Mulgarath]] attempts to do this to the main character by transforming into his dad. Much like in the FMA example, the main character has ParentalIssues and this ends up being a bad choice.]]
* In the ''Film/MortalKombat'' movie, the villain Shang Tsung tries to pull this gambit with Liu Kang by assuming the form of his dead brother Chan, whom Shang Tsung had killed at the start of the movie. It doesn't work.
* The monster in ''{{Phantoms}}'' turns itself into a little boy who looks like the kid Creator/BenAffleck's character accidentally killed in his former life in the FBI.
* The T-1000 from ''Terminator2JudgmentDay'' made use of this trope, shape shifting into Sarah Connor in an attempt to lure and terminate her son John. [[spoiler: The attempt fails when the real Sarah appears behind the T-1000, and John trusts her characteristic approach ("Get out of the way, John") over the duplicate's attitude of slumped defeat. The film's special edition, disappointingly, replaces this subtle indicator with an obvious shape shifting flaw (warped and misshapen feet).]]
* Inverted in ''Film/{{Dreamscape}}''. Assassin Tommy Ray murdered his father as a teenager. While fighting him in a dream, the [[{{Heroes}} heroic]] Alex distracts him by changing his appearance to that of the father and asking Tommy Ray why he killed him.
* In ''Film/TheExorcist'', the demon takes on the voice of Father Karras' recently deceased elderly mother.
* In ''Film/EventHorizon'', the title ship has taken over Dr. Weir. In an effort to get to Captain Miller, Weir takes the form of a flaming Edward Corrick, the man in Miller's back story whom he had to [[NoOneGetsLeftBehind leave behind]] in [[MyGreatestFailure his greatest failure]]. Miller doesn't buy the attempt to guilt-trip him for a minute though: "No. You're not Edward Corrick. I watched him die."
* Mystique tries this on her captors in ''Film/XMenTheLastStand''. She transforms into the President and threatens to have them all court martialed if they do not release her, and then a little girl who begs and cries to be let out. She finally turns mockingly back into herself when one of the guards threatens to empty a can of pepper spray in her face if she doesn't knock it off.
* In ''Film/HanselAndGretelWitchHunters'', when Hansel is beating up the evil witch Muriel, she takes on her beautiful form (FamkeJanssen) and begs for mercy. Hansel says, "Nice try." and continues the attack.
* In ''[[Film/ClashOfTheTitans Wrath of the Titans]]'', Perseus fights and defeats a minotaur. As he's about to finish it off, the minotaur suddenly starts talking in his son's voice, begging his "father" not to hurt him. Perseus kills it anyway.

[[folder:Literature]]
* OlderThanPrint: In ''Literature/ArabianNights'', one story involves a hero being told that he must kill a demon that is taking the shape of his mother. He refuses, is sent back where he started, and has to undertake all the other challenges of the quest again, as well as kill the copy of his mother.
* In the novel ''[[Literature/MythAdventures Myth-Taken Identity]]'', a group of shape shifters are running around disguised as the protagonist of the series, and their chief uses it against the protagonist's mentor in the climactic fight.
* A very neat example takes place in Creator/RogerZelazny's ''Literature/LordOfLight'' during, well, calling it fight would charitable, between Yama, the God of Death and Mara, the God of Trickery. The first of many CrowningMomentOfAwesome for Yama.
* The Franchise/StarWarsExpandedUniverse plays this one straight in ''Sacrifice''. [[spoiler: Jacen disguises himself as Ben when dueling Mara.]]
* ''Literature/MagicTime'': There's a whole swarm of these towards the end of the final book, divided into groups targeting each main character. (For instance, a doctor who survived Chernobyl fights animated radiation corpses. What, the title made you think it was a kids' book?)
* In Juliet Marillier's ''Literature/ChildOfTheProphesy'', the EvilMatriarch Oonagh does this during the middle of the climactic showdown: [[spoiler:while facing off her son and granddaughter, she takes on the appearance of the son's dead wife. Made worse by the fact that she killed the wife in the first place. This throws her son off-balance long enough that she would have killed him, had his half-brother not intervened.]]
* ''Literature/HarryPotter''
** A spell in ''Literature/HarryPotterAndTheDeathlyHallows'' gives [[spoiler: Ron Weasley]] a double-dosage of this trope - the ''two'' people closest and dearest to the victim manifest and give thorough counterpoint arguments for why YouSuck.
** A Boggart does this to Mrs. Weasley in ''[[Literature/HarryPotterAndTheOrderOfThePhoenix Order of the Phoenix]]'', tormenting her by transforming into an image of her children, dead. [[spoiler: Comes true in ''Deathly Hallows.'']]
* In ''[[Literature/TheSpaceTrilogy Perelandra]]'', Ransom is fighting the Un-man (the demon-possessed undead corpse of Weston, the previous book's villain) when it suddenly reverts to Weston's actual personality and begs for mercy. Ransom ignores it, and the narration points out that Weston's actual soul had most likely been completely subsumed long before.
* In a non-villainous example, Bartimaeus of ''Literature/TheBartimaeusTrilogy'' regularly appears in the form of Kitty Jones in the beginning of ''Ptolemy's Gate'', purely because he knows how much guilt his master still feels over Kitty's [[spoiler:apparent]] death in the previous book. He sometimes exaggerates the curves, though.
* Literature/CiaphasCain ('''HERO OF THE IMPERIUM!''') experiences this in one book: while on a raid on a Slaaneshi cult, he's quite surprised to see Amberley Veil (his boss with benefits), and can't bring himself to shoot her. In fact, hearing the soldier next to him comment in the same love-struck tones though with a different name, he is consumed by jealousy and about to shoot him. Fortunately Jurgen moves closer and dispels the effect, revealing her as the old brothel owner. "Impersonating an Inquisitor is a capital crime" indeed.
[[/folder]]

[[folder: Live Action TV ]]
* An episode of ''Series/RedDwarf'' features a genetic mutant which uses its shape shifting ability to drive its victims to extremes of some emotion, which it then feeds on/sucks out. So at one point Kryton becomes the victim of a ''literal'' Shape shifter Guilt Trip.
* The ''Series/{{Supernatural}}'' Season 1 episode "Skin" does this when Sam fights a shape shifter disguised as Dean. Sam can't kill him, so Dean does.
** Averted in Episode 5.05 "Fallen Idols" [[spoiler:in which a pagan god is about to take the form of John Winchester and gets killed before that happens.]]
** It happens again in Season six. When the boys prove unwilling to listen to her, The Mother Of All takes on the form of none other than Mary Winchester. [[spoiler: Still doesn't stop the Winchesters from ganking her.]]
* Subverted in an episode of ''Series/{{Angel}}'', when the MonsterOfTheWeek appears as [[spoiler:Wesley's]] distant father [[spoiler:[[KilledMidSentence and is unceremoniously shot]]]]. Notably this only happens after he threatens [[spoiler:Wesley's]] love interest, and since [[spoiler:Wesley]] did ''think'' it was his real father at the time he spends the next episode absent, apparently dealing with the revelation that he would have been willing to kill his own father. Made more humorous with all the other characters saying how they killed "their" fathers or mothers and haven't looked back since.
** Although not done intentionally, the demon Illyria [[spoiler: who has "hollowed out" and taken over the body of Fred]] notes that [[BloodKnight Spike]] has no problem punching her in the face.
-->'''Illyria''': This shell... you had affection for it.
-->'''Spike''': Tons. Loved the bird.
-->'''Illyria''': Yet you strike at her form without sentiment.
-->'''Spike''': You ain't her. I can see it. ''Lord'' knows I can smell it. And I got no problem hitting it.
* Also done in the ''Series/DoctorWho'' story "Planet of Fire".
* On ''Series/{{Heroes}}'', Candace (who can actually cast illusions, but used it in a way equivalent to shapeshifting) as Simone to Isaac.
* Notably averted on ''Series/{{Alias}}''. The heroes want to kill her ''extra''.
* The Worm creatures in ''Series/KamenRiderKabuto'' occasionally do this by showing the image of the person they'd replaced. One early episode has a Worm guilt tripping Kagami with the form of [[spoiler:his brother]], noting that since the Worm has all the memories of his victim, if the Worm dies the victim will be killed "a second time".
** It happens again in ''Series/KamenRiderDouble'''s movie, ''[[TheMovie Begins Night]]'', in which [[spoiler: a dopant poses as Shotaro's mentor and in turn, Kamen Rider Skull. When it is revealed that it's the Dummy Dopant doing the imitating, this pisses off Shotaro.]]
* On ''Series/BuffyTheVampireSlayer,'' this was [[BigBad The First]]'s main tactic. Creepily, its [[TheDragon Dragon]] [[SinisterMinister Caleb]] [[InvertedTrope inverted]] this---the First would turn into [[StrawMisogynist girls]] [[SerialKiller he had murdered]] so he could reenact killing them ''again.''
** The First even tells Caleb that most people dislike seeing people they've killed and that he is a rare exception. Caleb really likes [[ReminiscingAboutYourVictims Reminiscing About His Victims]].
* The ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS1E1TheManTrap The Man Trap]]" features an alien {{Shapeshifter}} who impersonates [=McCoy's=] old flame, causing him to hesitate to shoot it.
* ''Series/{{Lost}}'': The Smoke Monster [[spoiler:aka The Man in Black]] did this a lot to the main characters, though he was usually impersonating their beloved ones: [[spoiler:he appears to Jack as his late father, to Eko as his late brother, to Ben as his late daughter, to Richard as his late wife...]] you get the idea.
* The TARDIS inadvertently does this to the Doctor in ''Let's Kill Hitler'', turning into each of the Tenth Doctor's companions in turn:
-->''TARDIS turns into the Eleventh Doctor.''
-->'''Doctor''': Oh no no no no, give me someone I ''like''.
-->''TARDIS turns into Rose.''
-->'''Doctor''': Thanks! Give me guilt.
-->''TARDIS turns into Martha.''
-->'''Doctor''': Also guilt.
-->''TARDIS turns into Donna.''
-->'''Doctor''': More guilt.
* ''YoungDracula'' has a variant in which [[spoiler: Elizabeta]] turns into everyone Vlad cares about who he's disappointed or failed. Rather than doing it to gain an advantage, though, she's already beaten him and is just [[EvilGloating throwing his failures in his face before she kills him.]]

[[folder: Video Games ]]
* In the FinalBoss fight of ''VideoGame/BeyondGoodAndEvil,'' the BigBad's shape shifting {{Mooks}} mimic the forms of Jade's {{sidekick}}s. They accuse her in a CreepyMonotone of causing their suffering, and beg her to join the villain to take the pain away. Considering their [[LargeHam natural tendencies,]] this is especially unnerving.
** Worse, they do this right after the BigBad apparently absorbs them both, leaving you to wonder just how fake it is.
* Used a few times in a section of the first boss battle in ''MetalGearSolid4'', with Laughing Octopus, who uses her [=OctoCamo=] and [=FaceCamo=] to disguise herself as Naomi, then as Metal Gear Mk. II, with Otacon's voice. When you approach it, it attacks you, with Otacon's voice (although obviously not him speaking) making fun of you. Of course you can spot the flaws easily (she never changes out of her suit when in the face cameo and MK II is much bigger then its normal size. Plus Otacan doesn't flag you down with it in regular play.)
** You can briefly pull this off in ''MetalGearSolid3'' thanks to LatexPerfection. Put on the Raikov mask and uniform when fighting his gay lover to distract him for a moment. "Ivan is that you?"
* In ''VideoGame/StarFox Assault'', the final boss tries to pull this, although only with voices from the various people that died (or are presumed dead) during the storyline.
** Including James. Which is the clincher, since Fox knows that "[[OutOfCharacterAlert my father would ''never'' tell me to give up!]]"
* You can attempt one in ''MajorasMask'' against Igos Du Ikana with his knight captain's mask. Then fail completely.
-->"Ohhh! Keeta! Is it not Captain Keeta?!?... But you're so... T-Tiny!!!"
** Also done with the Gorman brothers of the same game while wearing their brother's mask, they get so upset looking at it they can't fight.
* The ''BaldursGate'' series features dopplegangers and other shapeshifters who like to impersonate other characters, but all of them shift into their normal forms when attacking, thus disqualifying some interesting scenes from quite exemplifying this trope. The closest to actually qualifying are the random dopplegangers that attack you in the Candlekeep catacombs that appear in the form of familiar minor characters and speak lines that don't actually make sense for those characters but are still related to what they might actually say; the greater dopplegangers near the end of the level try to convince you that it's all been an illusion and you've actually been killing the people that the dopplegangers looked like, but they stop pretending immediately if you choose to fight them. ''Throne of Bhaal'' also has a similar scene where some wraiths have a go at [[BreakThemByTalking Breaking You by Talking]] in the form of lost loved ones, but they too do it only ''before'' the battle is joined, not during it.
* Not quite an exact use, but referenced: In ''PaperMarioTheThousandYearDoor'', when [[spoiler: the Shadow Queen takes over Peach's body]], Goombella tells you that no matter how much it looks like your friend, you can't think of it that way and just have to fight it.
* The Holoprojection droid PROXY in ''StarWars VideoGame/TheForceUnleashed'' uses it to his advantage several times. Going against Vader as Obi-Wan Kenobi or against Boba Fett as his father Jango does not guarantee him victory, but ''does'' confuse his opponent for a few precious seconds.
** In the Wii[=/=]PS2[=/=]PSP version of the first game, Darth Phobos briefly adopts the appearance of Juno Eclipse to lure Galen into letting his guard down at the start of the fight. After you defeat her, she tries it again to stop you from killing her. It doesn't work.
** In the beginning of the sequel, Darth Vader orders Starkiller to destroy a droid that looks like Juno Eclipse, but he can't. The game's novelization includes a scene where Starkiller is confronted by a Juno droid again, as well as droids of his friends and father, but this time he declares that dreams and memories have no power over him anymore and destroys them all. [[spoiler: [[EvilKnockoff The Dark Apprentice]] destroyed his Juno droid and declared that he felt ''nothing.'']]
* Completely averted in ''VideoGame/{{Prototype}}''. If Alex is discovered by the military, while shape shifted, the military will not hesitate to fire on him -- even if you're in the guise of a respected commander, unarmed woman, or someone they wouldn't dare think about hurting otherwise. [[HilarityEnsues Hilariously]], if you use the Patsy ability to accuse someone of being Alex, the poor sod gets gunned down with an equal lack of restraint.
* In ''{{Metroid}}'' [[spoiler: Gandrayda]] pulls one of these once you [[ShapeshifterSwanSong defeat]] [[spoiler: her]]. First, [[spoiler: she changes into Ghor, then into Rundas, then into Samus. The whole thing takes less than a minute, and the only sound that comes out of her mouth is a scream, but the message to Samus is clear: You couldn't save them from TheCorruption, you couldn't save me from it, and you're not going to be able to save yourself. YourDaysAreNumbered, Samus.]]
* ''VideoGame/DantesInferno'': Lucifer takes the shape of Dante, along with his form massacring innocent people in his grand illusions, to break the will of Dante's wife's soul, Beatrice.
* In ''VideoGame/FinalFantasyTacticsAdvance'', the final totema attempts this in a cut scene. It changes from Ritz, to Doned, to Mewt (all characters with a close relation to the main character), and then finally to the main character himself, each one trying a different tactic to try to get him to [[spoiler: stay in the world and not destroy the final crystal]]. None of it works, though it does succeed in briefly mind fucking the main character.
** Similar to the above, in ''TacticsOgre The Knight of Lodis'', when you enter the VeryDefinitelyFinalDungeon, the first battle has [[BigBad Shaher]] attempt this on Alphonse and Eleanor, and who he takes the illusion of depends on the route you take. If you take Path A, he becomes [[spoiler: Rictor, Alphonse's commander who was possessed by Shaher and subsequently killed by Alphonse.]] If you take Path B, [[spoiler: he takes the form of Cybil, who felt she could no longer trust Alphonse and was later possessed by Shaher in a similar manner of Rictor in Path A]]. However, Alphonse doesn't buy it one bit, and simply lashes out at them and causes the illusion to break. Then again though, [[GenreBlind Shaher did actually say he would take their form to their face]], but to be fair, even before he said this, Alphonse wasn't buying it.
* In ''VideoGame/FableIII'', after having to leave behind your mentor Walter in the deserts of Aurora, the demonic Crawler taunts you with illusions of Walter begging for help and being brutally killed by the Crawler's shadow monster minions.
* In the FullMotionVideo game ''VideoGame/DraculaUnleashed'', Alexander, Helsing and Harker confront a friend turned vampire Juliet. They chase her back to her crypt where in a last ditch effort to save herself, changes into Harker and Alexander's wife and fiancee respectively. Harker sees through the guise but Alexander, apparently forgetting that that they're dealing with a supernatural force, nearly falls for it before Helsing stops him.
* In VideoGame/StarcraftIIHeartOfTheSwarm, AntiHero Kerrigan faces-off against ShapeShifter [[spoiler:Narud/Duran]]. The first tactic [[spoiler:he]] uses is to shapeshift into Jim Raynor, which causes Kerrigan to hesitate for a quick moment, before having her BerserkButton pushed and beats up [[spoiler:Narud]] mercilessly. Near the end of the fight, [[spoiler:Narud]] shapeshifts into Kerrigan before she was infested, which causes her to [[HeroicBSOD hesitate]] long enough for [[spoiler:him]] to stab her.
* In ''VideoGame/GodOfWarAscension'', Kratos starts strangling Tisiphone and then she transforms into Lysandra, his wife. He hesitates for a moment, then continues.
* In ''SpecOpsTheLine'', [[spoiler:a heavy trooper with an automatic shotgun "transforms" into Lugo, who was killed about an hour prior. Keep in mind nobody in this game has supernatural powers; the whole scene is Captain Walker's hallucination. He's guilt-tripping ''himself''.]]

* In ''{{Drowtales}}'' [[EldritchAbomination Khaless]] does this to Lulianne [[http://www.drowtales.com/mainarchive.php?order=chapters&id=1286 using the face of her niece Sael]], who Khaless may have killed and/or absorbed.
* A downplayed example appeared in everybody's favorite TropeOverdosed work, ''Webcomic/TheOrderOfTheStick'', when [[SpoonyBard Elan]]'s EvilTwin, [[SdrawkcabName Nale]], faces off against [[TheLeader Roy]]. If he was hoping that Roy would be reluctant to attack someone who looks identical to one of his party-members, he was [[BerserkButton DEAD WRONG]].
-->'''Roy''': I've been suppressing the urge to beat the crap out of someone who looks EXACTLY like you for a long, long time.

-->''Question 13: Shape Changers You're in a fight against a group of super villains, and one of them is a shape-changer. Suddenly, your dead girlfriend shows up in her underwear. Do you: A: Ignore her. It's possible that your girlfriend climbed out of her grave, changed into her panties, and got on a plane to see you during a fight, but it's probably the shape-changer, genius.''
* In a fan-made [[http://www.youtube.com/watch?v=GwP2vnQCoho battle between Darth Vader and Gandalf]], Gandalf takes on Anakin Skywalker's form to briefly shock Vader.

[[folder: Western Animation ]]
* ''WesternAnimation/AdventuresOfTheGalaxyRangers'': One of Mogul the Sorcerer's illusions is that of Zachary's wife. Mogul learns the hard way that this is Zach's fastest-acting BerserkButton. The Queen also pulls this trick on Zach during the DreamSequence in "Psychocrypt."
* In the {{Ben10}} episode "Permanent Retirement", Ben is beating the tar out of one of the evil aliens (already posing as Grandpa Max) as Wildmutt when it shapeshifts to close up its revealing wounds and says in Max's voice, "Now, you wouldn't want to hurt old Grandpa Max, would ya?" Ben-as-Wildmutt hesitates, allowing the alien to start wallopping him and forcing Gwen to have to remind him of reality.
* ''WesternAnimation/{{Gargoyles}}'': In "The New Olympians," Proteus irritates the prison warden Taurus by taking the form of his father (whom Proteus murdered) and begging to be released from jail.
* Used by [[FanNickname Brainithor]]'s drones in ''WesternAnimation/JusticeLeague Unlimited''. First he turns them into the Justice Lords, an alternate version of the League who [[KnightTemplar turned evil]] after their Franchise/{{Superman}} killed LexLuthor. It has different reactions on each member.
** When the Superman copy is about to be destroyed by Superman, it turns into Lex and says "ThisIsThePartWhere you kill me, right?" causing Superman to hesitate long enough for it to (almost) turn the tables.
** TheFlash and Franchise/{{Batman}} aren't affected: the Flash drone's attempt to HannibalLecture him fails miserably, and Batman defeats his double before it could open its mouth.
*** Flash's is particularly amusing, as him being aware of his [[TheHeart heart of the team]] status and playing it up is what allows him to ignore his double's words.
** Franchise/GreenLantern and Hawkgirl are at first hounded by their doubles, but, having gone through a nasty break-up, decide to switch partners and take the opportunity to "let out some steam".
** Franchise/WonderWoman's copy doesn't even speak, but she and Superman take a cue from the ex-couple and trade sparring partners, ending with them smashing their doubles into each other.
** [[FightUnscene And we never got to know how]] ([[WildMassGuessing or if]]) [[OffscreenMomentOfAwesome Martian]] [[MartianManhunter Manhunter]] actually beat his own clone during his ShapeshifterShowdown.
* ''WesternAnimation/LegionOfSuperheroes'': The MonsterOfTheWeek tries to save itself by turning into Ma Kent, but Superman roars, "You are not my mother!" and smashes it.
* During "Endgame" of ''WesternAnimation/TransformersAnimated'', Shockwave tries this on Bulkhead and Bumblebee, asking if they're really willing to take out their old friend Longarm by changing to his form. (In this case, he's only sort of playing head games, as Longarm and Shockwave were always the same person. [[spoiler: The Autobots feign sympathy for a minute before smacking him up.]]
* ''WesternAnimation/{{X-Men}}'':
** An inversion appears during a StoryArc of the animated series; a BrainwashedAndCrazy Morph shapeshifts into {{Wolverine}}'s most hated foes (including Sabretooth and Omega Red), trying to take advantage of Wolvie's fractured and tormented memories of said foes to drive him to insanity. Unfortunately for him, Wolvie's got plenty of experience with repressing those memories, and he only escapes by taking advantage of the one memory Wolvie ''can't'' repress: being forced to leave Morph to die after a semi-botched mission.
*** Prior to that, he shapeshifted into Wolverine's unrequited love interest Jean, and mocked him about how she'll never love him.
** Similarly, Mystique shape shifts into Ms. Marvel to dredge up a bad memory in Rogue of her past to try and guilt her into abandoning the X-Men and hook back up with her; the memory was of Mystique ordering Rogue to fully absorb Marvel's powers and personality, an action that caused Marvel to pop up on occasion as accusatory hallucinations. Rogue eventually had to ditch Mystique as a result, joining the X-Men and having Professor X block her mind of Marvel and the incident to keep the hallucinations at bay, but since he was at this time MIA and unable to keep the block in place, Mystique was trying to convince Rogue that she was the only one in the world who could help her with it.
* In ''{{Sym-Bionic Titan}}'', the main trio fights a chameleon monster that tries to do this, notably impersonating Octus' girlfriend Kimmy. Octus is fortunately, reminded that it's not really her (especially as the mutraddi's eyes are pretty much its own).
* ''GravityFalls'' has a variant in the episode "Into the Bunker"--after being shoved in a CryoPrison, the {{Shapeshifting}} monster tells [[SeekerArchetype Dipper]] that he will never find the Author, and that if he keeps trying, "''this'' will be the last form you'll ever take." It then transforms into a copy of Dipper, screaming in pain, as the freezing takes effect.
