->'''Silverbolt:''' I know what you're thinking. You don't know whether to kiss me or kill me.\\
'''Blackarachnia:''' I'm a black widow spider, you idiot! I can do both.
-->-- ''Franchise/{{Transformers}}: WesternAnimation/BeastWars''

The primary instincts of all creatures -- sex and death. If you can combine the two they become a bigger selling point. We're not talking about DeathBySex or InterplayOfSexAndViolence but something else.

Though not exactly graphic, the Kiss of Death is still sensual, seductive, and very, very deadly. While a character may be anxious about administering the KissOfLife, nobody is shy about giving the Kiss of Death. This may be because EvilIsSexy or the more practical reason -- once somebody catches onto what the kisser is going to do, they'd run for the hills. This is a favorite weapon of TheVamp.

The Kiss of Death comes in many varieties, including: hypnosis, narcotic effect, and [[YourSoulIsMine sucking out the soul of the victim]], which may or may not result in death, [[OurSoulsAreDifferent depending on the story]].

In addition, the Kiss of Death can also be a symbolic gesture -- the kiss itself does not bring death or harm, but the person who receives it knows that his days are numbered. The trope is named for the kiss from Literature/TheBible with which Judas Iscariot identified Jesus among his apostles and thus betrayed him to the Romans, making this OlderThanFeudalism.

The PG rated form of OutWithABang. Not to be confused with LastKiss, though it ''can'' overlap if the right circumstances are met.

See also KissOfTheVampire, where a vampire's bite is both pleasurable ''and'' deadly. This trope is not to be confused with 1947 film ''Film/KissOfDeath'', which does not even feature this trope.

SisterTrope to the TouchOfDeath.

This is a death trope, so '''Spoilers ahoy'''.



[[folder:Anime & Manga]]
* From ''Manga/{{Basilisk}}'', this is Kagero's primary ability. Whenever she gets aroused, she starts [[PoisonousPerson breathing out a deadly poison]], thus, whoever she kisses, she kills. And in fact this is how she kills [[spoiler:Koushirou Chikuma: since he's blind, Saemon confuses him via imitating Akeginu's voice, then Kagerou slips him a deadly kiss]]. Later, [[spoiler: she tries to use this ability on Tenzen alongside a NeckSnap but it fails since his powers is coming BackFromTheDead]], and at the end [[spoiler:only Oboro's Mystic Eyes could stop her from poisoning Gennosuke after Tenzen [[BreakTheCutie had driven her insane]] through ColdBloodedTorture.]]
* Kyoko Kirisaki from ''Manga/BlackCat'' is able to burn people alive by kissing them. She can do without, but [[CuteAndPsycho enjoys it that way]].
* In ''LightNovel/{{Campione}}'', Athena can do this by breathing the "Winds of Death" into the other person's mouth. She specifically used this method on Godou because the titular warriors are extremely resistant to external magic, but that resistance can be bypassed via the mouth. In the anime, Athena ironically gets this pulled on her by Metis, who drains her life energy and powers with a kiss, though Athena barely manages to survive.
* ''Anime/DarlingInTheFranxx'': this is the title of the opening song for the show, and refers to how riding with Zero Two will kill the male pilot after only three rides.
* In ''Manga/{{Dokuhime}}'' to kiss or come into any contact with a Poison Princess is deadly.
* High school student Ooshima in ''Manga/{{Emerging}}'' throws caution to the wind and shares a first kiss with his girlfriend, who is infected with a [[ThePlague fatal virus]]...making this example a kind of Suicide-by-Kiss.
* Izumi from ''Manga/FullMoonOSagashite'' prefers obtaining souls of dying young girls via kisses, because it's "more pleasant" than a scythe. [[spoiler: When he tries it on Mitsuki, Takuto stops him.]]
* ''Manga/LoveHina'': Naru Narusegawa, when possessed by a demon sealed within a sword, was also implied to have gained the ability to sap people's life force by kissing them.
* Fuka from a ''[[Manga/{{Naruto}} Naruto: Shippuuden]]'' filler arc has a technique that can literally kill the victim with a kiss (she asks if the victim wants French or soft) by sucking out their soul and their life force. She uses this to steal techniques and [[ElementalPowers elemental affinities]] (Fire, Wind, Lightning, Water, Earth).
* Yuufa from ''Anime/RagnarokTheAnimation'' [[spoiler:kissed Roan and slipped a cursed ruby in his mouth, French style]]. [[http://www.youtube.com/watch?v=28_Q1aXIKtc Really. Subverted Sleight of Tongue]].
* Used in ''Anime/ReadOrDie'' against Yomiko by [[spoiler:[[HoYay Nancy]], when it turns out she was TheMole for I-Jin leader Ikkyu (specifically, the lipstick mark it left had something that can affect her when activated by a remote)]]. It doesn't kill her, but she does get knocked out for quite a while.
* In ''Anime/SailorMoon'', one of Minako/Venus's [[LightIsGood light/energy]] attacks is called "Love and Beauty Shock" and she delivers it via first mimicking a kissing gesture and creating a heart-shaped projectile, then shooting the latter on her enemies.
* Kagura "Divine Goddess" Tennouzou's kiss in ''Anime/SpeedGrapher'' is lethal to anyone not infused with the Euphoria virus. And if you ''do'' have it, well, you get tremendous powers...[[BlessedWithSuck that can be also pretty deadly]].
* In ''Anime/UmiMonogatari'', Sedna's soldiers try to kiss Kanon to suck out her evil soul.
* Ran from ''Manga/UruseiYatsura'' has the power to suck the youth from someone by kissing them. She usually tries to use the power on an unsuspecting Ataru, who just thinks she liked him. She can also reverse the process with another kiss. Later in the manga, her "youth-stealing kiss" gets nerfed by the RuleOfFunny, as all it does is essentially making the victims act like stereotypical Japanese senior-citizens.
* In ''Manga/{{Yaiba}}'', we have Princess Kaguya, whose kiss allows her to suck the Youth out of her victims. [[LesYay And it only works on pretty girls.]] [[spoiler: Poor, ''poor'' Sayaka]].
* In ''Anime/YuGiOh5Ds'' Carly (as her SuperPoweredEvilSide) made Jack think that he had lost their duel and that she had done this to him, killing him with her kiss and turning him into a Dark Signer like herself (and that the world had been turned into a Hell that they could [[WeCanRuleTogether rule as king and queen]]). Possibly, she was indeed capable of doing this; however, [[spoiler: it was all an illusion meant to distract him from the actual move she intended to use to finish him off, and he snapped out of it before she managed it.]]
* During the final battle of ''Manga/RaveMaster'', Julia faces off against Jiero, an ice demon queen who can regenerate from any external injury. So when Jiero is paralyzed by an attack, Julia plants a wet one on her and uses her fire-breathing ability to flash fry all of Jiero's internal organs to kill her.

[[folder:Board Games]]
* Kiss of Death is also a move in chess. It means a moment where a Queen is right next to the opposite King, protected by a Mook (or the King) of her own army.

* ComicBook/{{Rogue}}'s power in ''ComicBook/XMen'' is stealing other people's life force [[PowerCopying and abilities]] by touching them. She first discovered her power by kissing her boyfriend for the first time, putting him in a coma. While any skin-to-skin contact will do the trick, for a long time her preferred means of using her power on others was to kiss them (at least men). She hasn't done this in awhile, however. Taking off her gloves has long been a sign that she means business.
* ComicBook/PoisonIvy of ''Franchise/{{Batman}}''. Her powerful floral toxins are often secreted from her lips and administered via a kiss. Like Rogue, she can use her powers through any skin contact, but enjoys doing it by kiss.
* The original ''ComicBook/XFactor'' (which was actually made up of the original roster of the ''ComicBook/XMen'') dealt with a one-shot mutant villain called Infectia who could mutate humans and turn them into monstrous slaves (who eventually died) by kissing them, and it seemed kissing may have been a prerequisite. (She used her power on plants, and tried to use it on their living, sentient Ship, each time using her kiss.) Curiously, trying to use it on the Beast had an unexpected effect (most likely because he was another mutant), restoring his intelligence and furry form that had been stripped of him by Comicbook/{{Apocalypse}}. (Much later, he tended to her as she was dying from the Legacy Virus, seeing as he kind of owed her one.)
* ComicBook/TheMightyThor nearly caught one from Hela, but she was so touched that Thor would have sacrificed himself for his girlfriend, that she let both go scot-free.
* A storyline in ''[[Comicbook/TheAvengers Avengers West Coast]]'' #98-100 (September-November, 1993), features an ArchivedArmy scenario. [[Characters/TheBorgias Lucrezia Borgia]], serves as an agent of the [[DemonLordsAndArchdevils Hell Lord]] Satannish. She is granted the power to kill with a kiss.
* ComicBook/TeenTitans villain Cheshire uses a much more gruesome version of this in an issue of ComicBook/SecretSix. She manages to convince a mercenary who is raiding her home [[MuggingTheMonster to try to rape her]]. She then kisses him, and bites off his lower lip in the process. Since her saliva is poisoned by a false tooth, this lets the toxin into his bloodstream and [[AssholeVictim he dies in horrific pain.]]
* The Creator/MarvelComics character Satana is a succubus who uses this as her preferred method of killing her victims; her kiss sucks out the victim's soul (which emerges from their lips in the form of a butterfly that Satana then collects), leaving the body a shriveled husk.
* A rare male-on-female example: A 1970s Comicbook/ManThing storyline featured a villain named Scavenger, who killed several women by kissing them, draining their life-force and reducing them to skeletons.

[[folder:Fan Works]]
* ''Fanfic/TheBridge'': Jeog's kiss temporarily paralyzes her victims, leaving her open to gut them or tear out their heart. Anguirus is so powerful that he recovers after a few seconds, allowing him to block her attack. Ki Seong manages to break free through sheer willpower.

[[folder:Films -- Live-Action]]
* ''Franchise/{{Batman}}''
** Catwoman from ''Film/BatmanReturns'' stuffs a taser into her mouth (non-shocky end in), grabs the power cables of a generator, and gives a kiss to CorruptCorporateExecutive Max Shreck. This, naturally, does not end well for Shreck.
** Poison Ivy from ''Film/BatmanAndRobin'' uses this as her preferred method for killing. She uses this to kill her former boss Dr. Woodrue as revenge for trying to kill her, two policemen when she breaks Mr. Freeze out of Arkham, and once off-screen to a victim at the Gotham airport. She seduces Batman and Robin through the film to [[BondBreaker break them apart fighting over her]] and eventually planned to kill them by sharing a kiss with each of them. [[spoiler:She eventually gets Robin alone in her lair and after [[JustBetweenYouAndMe explaining what she and Freeze have planned as a sign of trust]] she finally succeeds in kissing Robin, as a way of [[MotivationalKiss wishing him luck]]. But Robin had actually [[OutGambitted been one step ahead of her]] and wore [[CrazyPrepared rubber lips]] to protect himself incase her love for him was a lie, essentially stealing a kiss from her and being the only one in the film to [[NoSell survive a kiss with her]].]]
* In ''Film/BeneathThePlanetOfTheApes'', a mind-controlled Brent tries to suffocate Nova by forcefully kissing her.
* In ''Film/{{Lifeforce}}'', a naked space vampire woman killed (and zombified) a man with a kiss by sucking out his lifeforce...therefore, the name of the movie.
* In ''Film/{{Elektra}}'', Typhoid gives the eponymous character a lesbian Kiss Of Death which infects her with a deadly virus, complete with slow motion falling over and a sickly CG effect moving over her skin. [[spoiler:She gets better]].
* ''Film/KillBill'' has a very graphic version of this in the DudeShesLikeInAComa scene: [[spoiler:the guy who's going to rape the Bride gets his tongue ripped out when he tries to kiss her]].
* In the movie ''Shinobi: Heart Under Blade'', inspired by the same novel that led to the creation of Manga/{{Basilisk}}, Kagerou also has this as her ability but as a result of having been fed poison her entire life. She uses this ability to kill off a wild-man shinobi early in the movie. Later, it is revealed that this poison is apparently powerful enough to [[spoiler: kill another [[NighInvulnerable near-immortal, regenerating ninja who had perfected his art of "being bad at dying" over the course of three hundred years]] (She tried it in the manga/anime and movie, but failed).]]
* In ''Film/{{Species}}'', Sil kills someone while kissing him by sticking her tongue out through the back of his head.
* In the Hong Kong action movie ''Naked Killer'', the lesbian assassin kills her former mentor/lover with the poisoned lipstick trick.
* Subverted rather creepily in ''Film/TheMummy1999'' when Imhotep, who is mostly regenerated at this point, happens upon Evey while she is sleeping and kisses her. While they kiss, his face rots away until his whole mouth is in it's former state. She wakes up while this happens. Sort of like a reverse kiss of undeath.
* ''Film/StarshipTroopers2HeroOfTheFederation''. One of the PuppeteerParasite-like aliens is transferred this way, from a female soldier who was [[FullFrontalAssault walking around stark naked]].
* ''Film/XMenFilmSeries''
** Rogue's powers absorb the life force of anyone she touches. She has no control over this ability, and it first emerged while she was kissing her boyfriend, putting him into a three-week coma. In the second film, trying to kiss Bobby has a similar effect, but they end the kiss before any real harm comes to him.
** In ''Film/TheWolverine'', Viperís venom powers allow this. She uses this to dispose of a Japanese man who mistook her for a prostitute.
* In ''Film/KullTheConqueror'' the Red Witch gives such a kiss to Kull, though taking a liking to him, she does not give him the fatal version. (Apparently she could have if she wished). At the end of the movie, she beckons to him with a promise of a kiss (she's [[OneWingedAngel transformed into a fugly demon]] by that point btw) [[spoiler:and Kull gives her his own kiss of death, forcing the Breath of Valka into her body]].
* In the theme song of the ''Film/JamesBond'' film ''Film/{{Goldfinger}}'', girls are warned to beware of "The Kiss of Death from Mr. Goldfinger".

* Most forms of the "Vampire's Kiss".
* A Polish folksong known as 'The Kiss' tells the story of a young girl who gets kissed thrice by an unknown man (strongly hinted to be some form of a demon). She dies later that day, after relating the event to her mother.

* The Draghkar in ''Literature/TheWheelOfTime'' kiss their victims, consuming their souls the first time and their lives the second.
* The ''Literature/HarryPotter'' series had the Dementor's Kiss, in which the victim's soul is consumed. Unusually for this trope, though, this particular example was never portrayed as being sexy at all. The victim technically lives, but only in a braindead state.
* For as long as she can remember, the female protagonist of ''Literature/TheRavenCycle'' has been told by everyone in her psychic family that if she kisses her true love, he will die. She gets pretty sick of hearing it after a while.
* In the ''Franchise/StarWarsExpandedUniverse'' novel ''Darth Bane: Path of Destruction'', Bane's sometime helper Githany attempts to kill him by means of poisons applied to her lips. Upon kissing him - more than once, which ups the dosage, she gets out of sight to take the required antidotes. [[spoiler:Bane detects and counters the poison with the Force...except there were two poisons, an easier one to lull him into thinking he was now safe, and a harder to detect one that nearly kills him.]]
* Though she doesn't give it, the eponymous villain of ''[[Creator/HansChristianAndersen The Snow Queen]]'' can kill with three kisses; the first two mess up your head.
* After Mina from ''Literature/{{Dragonlance}}'' allies with Chemosh, the god of death, he gives her the power to kiss people and turn them into a [[OurVampiresAreDifferent more good-looking type of zombie]]. They don't look dead, but technically, the kiss does kill them.
* In the Creator/MichaelCrichton novel ''Literature/{{Prey}}'', [[spoiler:Julia kills multiple people with a kiss that transfers the deadly nanobots into them, almost killing her husband, Jack, once. She later begs Jack to "save [her] babies" with [=MRIs=] (the magnets kill the nanobots), telling him she kissed them too. It's not quite sexy, but it does still kill.]]
* In ''Literature/{{Neverwhere}}'', [[spoiler:Richard narrowly escapes having all his body heat siphoned away by the Velvet named Lamia.]]
* In ''Literature/TheJenniferMorgue'', by Charles Stross, Ramona Random, the hero's liason with the American "Black Chamber" has a soul-eating daemon bound to her. The means of operation is more of a bite than a kiss, however.
* ''Literature/TheDresdenFiles'':
** Thomas Raith has stated that Lord Raith, Thomas' father and the current king of the [[HornyDevils White Court]] vampires, is the one who ''invented'' the Kiss of Death. Whether or not any other White Court vampires can do this remains to be seen.
--->'''Thomas:''' That whole kiss-of-death thing in ''Film/TheGodfather''? He was where that phrase originated, only for him it was literal.\\
'''Harry:''' Really?\\
'''Thomas:''' Supposedly. I've never seen him do it myself, but Lara has, plenty of times. Madeline once told me that he liked to open conversations that way, because it made sure he had the complete attention of everyone still breathing.
** The reason Thomas has never seen the ability in action, incidentally, is that [[spoiler: Harry Dresden's mother, Margaret [=LeFay=] [=McCoy=], neutered Lord Raith's ability to feed, preventing him from restoring the power he needed to use this ability.]]
** In addition, the Red Court vampires have a drugged saliva which is addictive and keeps their victims from struggling before they feed. They call it their Kiss, which Harry lampshades as sounding sexier than "narcotic drool."
* In Nathaniel Hawthorne's short story "Rappaccini's Daughter", the titular daughter herself is poisonous, and won't let her suitor kiss her because she knows that would kill him. After spending enough time with her, however, Giovanni also becomes poisonous.
* Friedrich de la Motte Fouqué's Undine, bound by the rules of her mermaid people, has to kill her cheating husband, but since she still loves him, she is happy to oblige as he asks her if she could do it with a kiss.
* In ''Hardwired'' by Creator/WalterJonWilliams, "the Weasel" is a weapon which shoots out of your mouth; it is used to kill with a kiss.
* C.L. Moore's Literature/{{Jirel of Joiry}} is a feudal warrior maiden. In the story "Black God's Kiss" Guillaume the Conqueror besieges and captures Jirel's castle after a prolonged fight, kills her retainers and captures Joiry herself. He tries to force a kiss upon her whereupon she sinks her teeth into his neck, barely missing the jugular, and later she escapes from the dungeon where she was held. Determined to find at all costs a way of destroying Guillaume, Jirel enters a dark underground world, braving countless dangers, monsters and perilous black magic. By kissing the statue of a sinister black god she gains the power of giving Guillaume a Kiss of Death, returns to the castle, kisses Guillaume and has the satisfaction of seeing him immediately die in great agony. Only when seeing him dead does she realize that she had been passionately in love with Guillaume all along and that now he is dead "the light had gone out of her world" - and she bursts out bitterly crying for the beloved enemy she had killed.
* In ''Literature/ThoseThatWake'''s sequel, ''What We Become'', the Old Man kisses Rose to [[spoiler:extract the neuropleth from her, which would doom New York and the world]].
* In the Literature/SimeGen series of novels, humanity has split into two races, the Gens that produce [[LifeEnergy selyn]], and the Simes, who do not make their own and must take it from Gens to live (which is fatal if the Gen is at all afraid of the Sime). Simes draw selyn by wrapping their forearm-tentacles around the victim's own forearms and then making lip contact.
* ''Literature/PleaseDontTellMyParentsIBlewUpTheMoon'' (sequel to ''Literature/PleaseDontTellMyParentsImASupervillain''): After She Who Wots gives a boy a rather chaste kiss on the lips, he is paralyzed and his eyes start bleeding. It's not clear if she did it on purpose or not.
-->'''She Who Wots:''' Andrew Stickler wanted to get to know me better. Now he does.\\
'''Spider:''' I'll see that he gets medical attention.

[[folder:Live-Action TV]]
* ''Series/{{Smallville}}'':
** Lex had a fiancée whose exposure to kryptonite while she and her boyfriend were ''[[DeusSexMachina in coitus]]'' gave her the power to hypnotize men (for the duration of one command) with a kiss.
** Also, Maxima's kiss in this verse is highly toxic. Her main motivation is to find a man who can survive it. It ends up being Clark Kent.
* ''Series/{{TheFlash2014}}'':
** Killer Frost, Caitlin's Earth-2 doppelgänger, demonstrates a kiss that will absorb the body warmth of her victim and freeze them to death. It doesn't work on her husband, [[PlayingWithFire Deathstorm (Ronnie Raymond)]], though.
** In season 3, [[spoiler: Caitlin kisses Barry to cause hypothermia to him.]]
* In ''{{Series/Firefly}}'', [[spoiler: Saffron]] knocked out Mal with a poisonous kiss. Inara was also temporarily paralyzed from the soporific lipstic left on his lips, when she, relieved that he was only unconscious, [[TheyReallyDoLoveEachOther impulsively]] kissed him. Of course, after he wakes up, Mal assumes [[GirlOnGirlIsHot what any guy would assume]] and thinks [[spoiler: Saffron]] also seduced Inara, who is too embarrassed by the whole thing to correct him.
* In "Inca Mummy Girl" from ''Series/BuffyTheVampireSlayer'', the mummy steals the life of various men in order to keep herself alive.
* In ''Series/{{Torchwood}}'', Captain John Hart has "paralyzing lipgloss". It's a kiss of death because if you aren't treated for it within two hours, your major organs shut down.
* In the ''Series/DoctorWho'' episode ''Let's Kill Hitler", [[spoiler:River has one of these for the Doctor. She later has a change of heart and resurrects him. [[KissOfLife With another kiss]].]]
* In ''Series/TheDresdenFiles'', vampire saliva contains a narcotic that's powerfully addictive when absorbed through the skin (or ingested). Preferred delivery method? A kiss.
* In ''Series/TerminatorTheSarahConnorChronicles'', Catharine Weaver, disguised as a different beautiful woman, seduces a victim, then sends a liquid-metal tentacle down his throat to strangle his heart through his esophagus and kill him.
* ''Series/GilligansIsland'' episode "The Invasion". During a dream sequence where Gilligan is a secret agent, Ginger (as an enemy agent) tries to kill him with poison lipstick.
* ''Series/GetSmart'': A KAOS femme fatale uses poisoned lipstick to kill Max, but he's wise to her and uses...fake lips.
* ''Series/BigWolfOnCampus'' takes its usual sober, low-key approach to the subject: Sloane the assassin blows a storm of ''[[ProjectileKiss projectile]]'' Kisses of Death at our heroes.
* ''Series/TheXFiles'': "2Shy"'s MonsterOfTheWeek uses kissing as a pretense to regurgitate acid into his victims, pre-digesting their flesh so he could suck out their fat.
* In ''Series/DarkAngel'', Diamond kissed the man who had her infected with a terminal disease, passing it onto him. Since she's a lesbian, he's also the first man she's ever kissed.
* ''Series/TheNineLivesOfChloeKing'' feature a race called the Mai. The Mai are only allowed to be intimate with other Mai and the results can be deadly for humans. Unfortunately, Chloe doesn't find this out until after she's kissed a human.
* ''Series/H2OJustAddWater'' had a one off. Rikki lost control of her heat powers and nearly boiled Zane alive the first time they kissed. He was knocked unconscious and left with red skin for a few days, but it's implied how dangerous the situation could have been.
* In the ''Series/{{Supernatural}}'' episode [[Recap/SupernaturalS02E22AllHellBreaksLoosePartTwo "All Hell Breaks Loose, Part Two" (S02, Ep22)]], the kiss between Dean and the crossroad demon seals the contract, which will end in Dean's death in one year.

[[folder:Music Videos]]
* Almost a decade before ''Series/TerminatorTheSarahConnorChronicles'' example above, in the music video for "[[http://www.youtube.com/watch?v=FGrYXBwdlPU The World is not Enough]]" by Music/{{Garbage}}, a robotic Shirley Manson (who would go on to play Catharine Weaver) kills a test subject by burning him to death through kissing him. "She" then kills the original Shirley Manson the same way, and then explodes during a packed concert.

[[folder:Myth and Religion]]
* In Jewish tradition, {{God}} honored Moses and his siblings Aaron and Miriam by taking their souls with a kiss rather than by sending the [[GrimReaper Angel of Death]].

[[folder:Tabletop Games]]
* One powerful spell in ''TabletopGame/ArsMagica'' lets a mage deliver these, killing instantly without the usual MagicalIncantation.
* ''TabletopGame/DungeonsAndDragons'':
** Succubi and Incubi in all editions have an energy drain attack delivered though a kiss or another "act of passion." It takes more than one to kill someone (frequently, eight or nine by the time the players are high enough level to encounter one), though. The kiss often has a ''suggestion'' with it, to convince the victim to keep kissing the demon.
** [[OurMermaidsAreDifferent Nereids]] in some editions can drown a man who kisses them, but a nereid usually only does this to someone who has the nerve to [[ForcefulKiss force a kiss from her.]] (Or to possibly to someone who steals the shawl that acts as her SoulJar; a nereid can be MadeASlave by anyone who succeeds in taking it, but that person must be ever vigilant, as she can be cunning in trying to get it back.)
** The darklord Ivana Boritsi of Borca in the ''TabletopGame/{{Ravenloft}}'' campaign setting possesses this ability (due to various types of poisons applied to her lips). She is explicitly so toxic that she can kill even creatures immune to normal poisons. She also employs a team of enforcers called the Ermordenung who are given a lethally poisonous touch via an alchemic process known only to her (the leader of which was [[HeterosexualLifePartners her best friend as a child]]); they only need to touch a victim with bare skin to kill them, but a kiss (their preferred method of killing a victim of the opposite sex, usually through deception and seduction) is the deadliest method of doing so.
* ''TabletopGame/{{GURPS}}: Ultratech'' advises using the Ripsnake (a mechanical weapon that shoots out of your mouth) while kissing.
* ''TabletopGame/{{Pathfinder}}'' has {{Psychopomp}}s in service to the goddess of death; one variety, the Catrina, helps ease people into the afterlife with a painless kiss of death. As festively dressed skeletons, that's quite a feat.
* ''TabletopGame/SirenTheDrowning'' has Sirens most commonly replenishing their [[{{Mana}} Pneuma]] by draining people's soul with a kiss. Downplayed in that it's not required to kill or even durably harm the victim; if they show restrain and stop in time, this will just drain willpower, which the person can then recover over time by resting. When they don't, however, it can result in the man falling in catatonic state.
* ''TabletopGame/{{Warhammer}}'' has the Dogs of War character [[DysfunctionalFamily Lucrezia Bor-]] [[{{Expy}} I mean]] [[CaptainErsatz Lucrezzia Belladonna]], an expert with poisons and toxins, including poisoned lipstick. One story has her kiss the tip of a knight's lance, and his unhorsed opponent dying within seconds. When asked if the lance was poisoned, she replied that she had just kissed it and she didn't feel at all unwell...

* In Kander and Ebb's musical version of Manuel Puig's ''Literature/KissOfTheSpiderWoman'', the titular (imaginary) character kills with a kiss. The hero, a prisoner in a hellish Argentine jail, sees her whenever someone around him is poisoned or tortured, and worries that she will come for him next.
* In the Austrian musical ''Theatre/{{Elisabeth}}'', Death is a major character. He is ''made'' of this trope.
* In the Austrian production of ''Theatre/RomeoEtJulietteDeLaHaineALamour'', Tybalt plants a big kiss on Mercutio in the latter's death scene. Tybalt's actor, Mark Seibert, would go on to play Death in ''Elisabeth'', who [[spoiler:kills Prince Rudolf with a kiss.]] Lukas Perman was Romeo and Rudolf opposite Seibert.

[[folder:Visual Novels]]
* In ''VisualNovel/AnimamundiDarkAlchemist'', [[spoiler:Ruthberg does this to Dashwood]].

[[folder:Video Games]]
* ''VideoGame/PlanescapeTorment'' features a succubus character named Fall-From-Grace, who (as is normal for her species in ''TabletopGame/DungeonsAndDragons'' canon) can drain the life from her victims by kissing them. However, as a ''reformed'' succubus, she is reluctant to do this except in a dire situation (though the definition of a "dire situation" is [[GameplayAndStorySegregation whenever the player directs her to]], considering she has the kiss as one of her attack commands). [[spoiler: Whenever the protagonist speaks to her, you have the option of having him kiss her if his Wisdom score is low enough; due to his ability to come back to life every time he dies, it's only a temporary setback if you choose that option, but you quickly learn not to do it again.]]
* Karim in ''VideoGame/EternalDarkness Sanity's Requiem'' suffers from this fate. Interestingly, it's something he needs to do in order to be able to [[spoiler:protect the artifact]].
* ''Franchise/MortalKombat''
** The franchise is probably the biggest TropeCodifier here, where several characters use this as a Fatality. Sonya Blade blows her kisses and they either burn or eviscerate the enemy, depending on the game. [[http://www.youtube.com/watch?v=mmtDatkm2ag Kitana]] and Tanya directly kiss the enemy on the head or the lips, causing them to either swell up and explode or twist in several painful ways...then explode, though it would have been arguably more gruesome if the opponent just fell to the floor a twisted, screaming mess.
** Likely the grossest example of this Trope is Mileena's execution at D'Vorah's hands in ''X'' -- she forcefully kisses her, vomiting a swarm of insects down Mileena's throat that proceed to tear her apart from the inside. Cassie, who witnesses it, remarks, "Well, thanks for that. I know I'll never eat again."
* This is Tira's Finishing Move in ''[[VideoGame/SoulSeries Soul Calibur IV]]''. [[http://www.youtube.com/watch?v=gPmn9uCwEuY Nope, I'm serious]].
* ''Franchise/{{Pokemon}}'' has the move Draining Kiss, which does damage to the opponent and absorbs said damage to heal the user.
* In ''VideoGame/DevilMayCry 3'', the vampire Nevan does this if you don't run away quick enough, making some fangirls commit suicide in order to see Dante kiss someone. If you have enough Devil Trigger, you don't have to retreat - she can't steal a demon's LifeEnergy, and she's a sitting duck while she's performing the move, so when she gets close enough hit the Devil Trigger and smack the hell out of her.
* Subverted in ''VideoGame/MetalGearSolid3SnakeEater'', when EVA/Tatyana threatens the always-nervous Sokolov with a tube of lipstick, who thinks she's trying to kill him. She then turns the lipstick around, puts it on, and walks away. [[note]] This is because she also carries a lipstick-shaped gun that's often used by the KGB, which, incidentally, is called the Kiss of Death.[[/note]]
* [[MsFanservice Karst's]] "Heat Kiss" attack in ''VideoGame/GoldenSun: The Lost Age'', a powerful debuff in the form of a blown kiss.
** The Ice Queen's "Icy Kiss" in ''[[VideoGame/GoldenSunDarkDawn Dark Dawn]]'' is a more literal example, since it can be a OneHitKill.
* A non-fatal variant occurs in ''VideoGame/TheLegendOfHeroesTrailsInTheSky'', when Joshua kisses Estelle. He has a [[InstantSedation fast-acting]] sedative on his lips, which knocks her out and prevents her from following.
* ''VideoGame/EarthBound'' has an enemy that's actually called the Kiss of Death, which is only a smiling mouth with huge red lips. It has the ability to give the "kiss of death", which poisons the victim. There's [[UndergroundMonkey a similar enemy]] called the French Kiss of Death.
* In ''VideoGame/Disgaea3AbsenceOfJustice'', Marjoly has the ability known as [[http://www.youtube.com/watch?v=NioBWe-Nk_0 "Oh, Marjoly"]] in which she delivers a long and deadly kiss to her target that for some reason deals massive damage. It's Disgaea, so just roll with it.

* In 'Webcomic/{{Pandect}}'', all Servant Aces have a body part which is poisonous to anyone who touches it. For one character, it's his lips.

[[folder:Western Animation]]
* Poison Ivy can not only kill with her kiss, she can occasionally hypnotize people with it. In the ''WesternAnimation/BatmanTheAnimatedSeries'' episode "House and Garden", she did this to get out of Arkham, tricking her psychiatrist into accepting a kiss, making him her slave, and then ordering him to write her a clean bill of health. (Then pretending she married him; she almost had Batman himself fooled and might have gotten away with it completely if the same psychiatrist had not been one of Robin's college professors, and Robin knew that the guy's former wife had custody of the two sons that Ivy claimed he had - and that [[ImposterForgotOneDetail his children were actually daughters]].)
* The ''WesternAnimation/CodenameKidsNextDoor'' MadeForTVMovie: a zombified Kuki gives Wally TheVirus by kissing him. A virus that, mind you, turns people into "Senior Citizombies" -- that's right, zombie old people. Number 362 and the other kids find this as {{Squick}}y as the audience does.
* ''WesternAnimation/TransformersAnimated''. Blackarachnia ''usually'' does a non-deadly version of this -- and it's a spidery kiss, not a kiss on the lips: she stabs her victim with the legs that stick up over her shoulders and temporarily drains whatever special power they have. However, as proved by her attack on Prowl and Bumblebee in "Black Friday", she can give a deadly one by adding an extra dose of venom, giving the victim two hours to have the antidote administered before they die. [[spoiler:Don't worry, while she never actually hands Optimus the antidote, when he goes to [[ConverseWithTheUnconscious see Prowl and Bee and apologize for being unable to save them,]] he finds the antidote on the ground by them and muses that there may still be some good left in her.]]
* {{Subverted}} on ''WesternAnimation/AdventureTime''--[[NonHumanSidekick Jake]] is literally kissed by [[TheGrimReaper Death]] (complete with FootPopping!), but rather than hurt him it fixes the LaserGuidedAmnesia he got from drinking from the [[Myth/ClassicalMythology River Lethe]].
* Played straight in ''WesternAnimation/ThePowerpuffGirls''. The girls kiss their male counterparts, which causes them to explode.
** Completely subverted when the boys come BackFromTheDead and the girls' kisses only make them bigger and stronger.
* In the ''WesternAnimation/SpicyCity'' episode ''Sex Drive" in which the prostitute Virus is kidnapped and implanted with cyber genetic parts, every time she kisses someone she electrocutes them to death because of a device hidden under her tongue.
** The last episode "Raven's Revenge" Raven has been infected with a virus that causes anyone she kisses to slowly die.
* In ''WesternAnimation/TeenageMutantNinjaTurtles2012'', that's how a snake-mutated Karai gives Casey his dose of venom.
* The introduction episode of Morgana in ''WesternAnimation/DarkwingDuck'' is about how Morgana's relatives want her to give one to Darkwing by using a poisoned lipstick.

[[folder:Real Life]]
* An rather depressing example: Some time after being born, a baby suddenly fell ill and, despite weeks of life support, passed away from major organ failure. The cause? A virus contracted from a cold sore... from the baby's father.
* And the man who was allergic to nuts who died after being kissed by his girlfriend who'd just eaten some peanut butter.

!!Symbolic Examples
[[folder:Anime & Manga]]

* The Chinese Amazon kiss of death delivered by Shampoo in ''Manga/RanmaOneHalf'': it's a tribal custom when defeated by an outsider woman to kiss them, which signifies a promise to hunt the recipient down to the ends of the earth and kill them. And they mean "to the ends of the earth" literally: Shampoo chased Ranma through all of China and to Tokyo to kill his female form...
* Mireille Bouquet from ''Anime/{{Noir}}'' receives an excessively long one of these [[LesYay from a woman named Silvana Greone]], aka [[NamesToRunAwayFromReallyFast Intoccabile]]. And she tries to punch her afterwards (episode 9, 11:25), as said woman is a MafiaPrincess so the message behind the gesture is clear, and Intoccabile has scared the wits outta her since they first met as children. It's also clear that Silvana does it both for the fear effect and just to fuck with Mireille's head some more.
* ''Anime/PrincessTutu'': Rue kisses Mytho as she literally yanks his ability to love out of his chest.
* In ''Anime/{{Pretear}}'' episode 11, Takako kisses Mawata after successfully driving her into despair, in order to use her soul as a power source for what turns out to be a huge evil tree and then lock Mawata inside of it.
* In the anime of ''Anime/ChronoCrusade'' and at the culmination of his BreakTheCutie, Aion kisses Rosette. [[BerserkButton Chrono does not approve.]]
* Yoko of ''Anime/TengenToppaGurrenLagann'' shares a kiss with two separate characters, [[spoiler:Kamina and Kittan]], immediately preceding their deaths. To be fair, [[spoiler:Kittan kissed her ''knowing'' that his next mission was suicide]].
* In ''{{Manga/Berserk}}'', it is debatable whether [[spoiler: Femto/Griffith]] doing this to [[spoiler: Casca]] counts; he was just about to brutally rape her, and so a ForcefulKiss is not exactly out of place. However, since [[spoiler: Casca]] had already been marked for death by the demon brand, and did not realise yet that [[spoiler: Griffith]] was the one causing all hell to break loose, the kiss served a similar purpose to this trope by making it clear just how much trouble she was in.
* In ''Manga/FutureDiary'', if you kiss Yukiteru and your name isn't [[{{Yandere}} Yuno Gasai]], you ''will'' be dead by the end of the episode.
* [[SubvertedTrope Subverted]] in ''Anime/FairyTail'': [[spoiler:At first, this is heavily implied to be how the First Guild Master of Fairy Tail, Mavis Vermilion, died. She had the same {{Curse}} as Zeref that rendered her immortal and killed those she loved, whose only CurseEscapeClause is when one forgets the value of life. She suffered a rather ironic death after Zeref expressed love to her through a kiss and seemingly broke the curse for Mavis, leaving her vulnerable to Zeref's curse, thus killing her.]] In reality, [[spoiler:Mavis ''didn't'' die; while her body was, for all intents and purposes, clinically dead, her soul was still tethered to her body, and it wasn't until nearly a century later that she was resurrected. She states that she ''forced'' herself to believe she didn't love Zeref, out of fear that the exact same thing would happen to him. Oh, and it [[SubvertedTrope wasn't]] a KissOfDeath; she just apparently didn't want to tell the rest of the guild that it was actually OutWithABang.]]

[[folder: Comics]]
* ''[[ComicBook/{{Huntress}} Batman/Huntress: Cry for Blood]]'' contains an example of the purely symbolic kind. It also differs from a more typical example of this trope in that it has no erotic character, and the recipient doesn't realize what it means. It is obvious to the reader, however, that when Helena kisses her father on the cheek, that she is going to kill him.

[[folder:Films -- Live-Action]]
* A big joke (almost to the point of RunningGag) in the ''Franchise/PiratesOfTheCaribbean'' sequels is that every guy Elizabeth kisses dies. Jack in ''Film/PiratesOfTheCaribbeanDeadMansChest'', Norrington, Sao Feng, and [[spoiler: Will]] in ''Film/PiratesOfTheCaribbeanAtWorldsEnd''. Even [[spoiler: her father (who she probably kissed a few times, considering how big of a DaddysGirl she is)]] dies. Lampshaded in the third movie by Jack, who tells her that "Once was quite enough" when she runs up to him to embrace him.
* Michael Corleone's kiss of death to the person who betrayed him in ''Film/TheGodfatherPartII'' is one of the most iconic examples of the symbolic version ever. "You broke my heart. You broke my heart." [[spoiler: His ''own brother'' Fredo betrayed him out of jealousy.]]
* ''Film/BladeRunner''. Roy Batty kisses Eldon Tyrell just before squashing Tyrell's eyeballs into their sockets and crushing his skull, killing him.
* Just barely averted in ''Film/AmericanGangster''. When he sees one of his brothers in a flashy suit that might draw the attention of the cops, [[VillainProtagonist Frank Lucas]] sits him down to remind him that potentially drawing attention and notice is a bad thing for major drug dealers. When, during that conversation, the brother also lets it slip that he talked about Frank with one of his rival drug lords (and thus, in his naivete, possibly gave information to this other drug lord), Lucas, who has dealt extensively with the Mafia, gives his brother an enormous kiss and says "You know, if you weren't my brother, I'd have to kill you." They both laugh. Much later in the film, when the brother screws up again, however, Frank [[NoHoldsBarredBeatdown beats him viciously for it]]. And it's all the scarier for coming out of nowhere and with no warning.
* ''Film/BlackWidow'' (1987). The kiss Catherine Petersen (murderess) gives to Alex Barnes (Justice Department investigator). Aside from providing some LesYay, it also shows that Catherine intends to mess Alex over by framing her for Paul's death.
* Averted in the theatrical version of Marvel's ''Film/{{Daredevil}}'' and done in the Director's Cut. After killing Elektra's father, unintentionally framing her boyfriend, beating her while hitting on her, mockingly treating her revenge like a date, and instantly developing an attraction to her, Bullseye cuts her neck and, intending to use her own sai against her, tries to give Elektra her last kiss. In the Director's Cut, he manages to give her the kiss while she is gutted in the air.
* ''Film/ThreeAmigos''. Just before Ned's duel with The German, Jefe approaches him and kisses him on both cheeks, because he's sure the German will kill him.
* ''Film/TerminatorSalvation'': Marcus Wright is about to be executed by lethal injection when he is visited by the terminally ill Dr. Serena Kogan to convince him to volunteer his body to science. He agrees on one condition: a kiss. She obliges, leading him to remark "So that's what death tastes like".
* In ''Film/UnderworldBloodWars'', Semira mockingly kisses Alexia on the lips before slitting her throat.

* Sort of in ''Literature/TheHouseOfTheSpirits'', when Esteban is moving Rosa's body to another tomb and opens up the coffin to have one last look at her. She is completely preserved until he kisses her, after which she degrades very rapidly (keep in mind this is occurring years after she died).
* In ''Literature/{{Holes}},'' a schoolteacher named Kate Barlow angrily refused the local sheriff's offer to [[spoiler:save her black lover from being lynched]] if he kissed her. When she failed to [[spoiler:save her lover]] herself, however, she went back and kissed the sheriff in his sleep, then killed him. After that she left town and became the infamous bandit "Kissin' Kate Barlow," who robbed many (including the protagonist's ancestor) but would only kiss the ones she killed.
* In the ''Franchise/TombRaider'' novel ''The Man of Bronze'', [[Franchise/TombRaider Lara Croft]] mentions that she once killed a man while kissing him.
* ''Film/TheGodfather'''s Kiss of Death is also parodied in ''Literature/TheExecutioner'' series by Don Pendleton: "Nick told me to kiss you first -- I told him you were too damn ugly."

[[folder:Live-Action TV]]
* ''Series/{{Oz}}''. When Chucky Pancamo kisses Peter Schibetta in a prison corridor, the latter realises instantly what it means and starts shouting "No! No!" Chucky kills him seconds later.
* One of the most poignant moments in ''Series/XenaWarriorPrincess'' is when she has to kill her undead lover Marcus (long story). She stabs him with his sword, and then passionately kisses him as he dies in her arms.
* In ''Series/{{Supernatural}}'', when a person sells their soul to a demon, they seal it with a kiss, and then they die ten years later. Note that this applies to ''all'' demons -- Crowley has made himself quite the master of HoYay and FoeYay due to his insistance on following this particular rule.
* On ''Series/That70sShow'', Kelso is breaking off his cheating relationship with Laurie. Laurie sees Jackie, Kelso's cuckolded girlfriend, over Kelso's shoulder and asks for "one last kiss", thus ensuring that Jackie will see them kissing and break up with Kelso. The episode is actually titled "Kiss of Death."
* An episode of ''Series/TheDukesOfHazzard'' dealt with a group of mafiosos who were having a meeting in the Hazzard County Jail (long story). Bo and Luke got caught snooping around and were brought before the mob boss, who kissed both of them. Luke put it together that he just gave them "the kiss of death".

* Music/NewOrder's [[{{Irony}} aptly named]] "[[http://www.youtube.com/watch?v=--pSWLEVGhY Perfect Kiss]]".

[[folder:Myths & Religion]]
* For much of the Western world, [[Literature/TheBible Judas kissing Jesus]] in the Garden of Gethsemane is the TropeCodifier.

[[folder:Pro Wrestling]]
* For a short time, Wrestling/MickieJames had her [[http://www.youtube.com/watch?v=vkSCN7UZyVQ Long Kiss Goodnight finisher]], but it disappeared when WWE went PG. [[GirlOnGirlIsHot Dammit!]]
* It's also been used as a saying when a wrestler gets put with a gimmick that kills his career. An example would be Terry Taylor as The Red Rooster.
* During their feud in late-2004, Wrestling/TrishStratus called Wrestling/{{Lita}} "The Walking Kiss Of Death" and sarcastically asked whose career she'd kill next. Lita responded by kissing Trish.
* Bray Wyatt of Wrestling/TheWyattFamily occasionally kisses his opponent on the forehead before hitting him with his finisher.

* ''TabletopGame/Warhammer40000'': Eldar Harlequins have the Harlequin's Kiss, a monofilament RazorFloss that does horrible things to individual units.

[[folder:Western Animation]]
* ''WesternAnimation/TheSimpsons'':
** ''Film/TheGodfather'''s kiss of death gets parodied with the mobsters. "The kiss of death. That ''can't'' be good."
** Parodied again during Homer's stint as Mayor Quimby's bodyguard. Fat Tony tells Homer to give Quimby this and he obliges. When Quimby tells him, "You moron, that's the kiss of death!" Homer worries that he did it wrong and goes in for another.
** As a non-mafia related example, in one episode, the oldest man in Springfield dies after a model kisses him for winning an award for it After Mr. Burns is called to take the award instead, he avoids the model, calling the trope by name for his reasoning.
* And in ''WesternAnimation/{{Futurama}}'':
-->"I know Big Vinnie said he was giving me the kiss of death, but I still think he was gay."\\
"Did he use his tongue?"\\
"...A little."

[[folder:Real Life]]
* There are instances when an individual [[TemptingFate tempts fate]], such as declaring [[NothingCanStopUsNow failure impossible]] in a sporting event, that is jokingly referred to as the "Kiss of Death", ''especially'' if said person is notorious for bad judgement.
* Lampshaded, then subverted, in [[http://www.youtube.com/watch?v=Djl-4joUyB4 this skit from Anime Boston 2011]].
* When UsefulNotes/JosefStalin kissed a guy in the cheek, he kisses him again in his funeral.
