Bob's a villain. He's an evil, cruel, sadistic bastard. But no matter how many [[KickTheDog puppies he kicks]], nuns he throws into open wells, or orphans he starves to death, Bob always has a girlfriend. Funny, huh?

The villain's paramour is almost always defined [[SatelliteCharacter in terms of]] [[SatelliteLoveInterest her (or his) relationship to the villain]]. The role she plays in the plot, however, depends a great deal on how her character is defined. She may be [[LadyMacbeth just as evil as he is and actually share his goals]]. She could be [[TheDitz a ditz]] who doesn't really like evil things but just isn't bright enough to realize she's in a relationship with a very bad person. In stories where the villain is allowed to be sympathetic on some levels (GreyAndGrayMorality, PunchClockVillain, etc.), she might love him for his better qualities.

Depending on her skill set she might actually be a valued member of the villain's criminal organization, in which she might overlap with TheBaroness or DarkChick. If not, expect much grumbling from [[EvilMinions his underlings]] about why the boss even bothers to keep her around.

See Also: PerkyFemaleMinion for a similar character (usually) without an explicit relationship and UnholyMatrimony for a couple that are each villains in their own right. A LadyMacbeth is generally older and goads her partner into committing evil acts. Sometimes subject to a HighHeelFaceTurn.

[[folder:Anime and Manga]]
* C.C. in ''CodeGeass'' is ''seen'' as this InUniverse. Her role is somewhat muddled by the fact that while she is directly behind Zero's actions, none of the Black Knights actually know what her real role is, and assume she's Zero's mistress. Zero doesn't care, but C.C. at least attempts to correct Tamaki about this, though he doesn't believe her. In reality, [[SubvertedTrope she doesn't really fit this trope]], having a definite character and ulterior motives beyond helping Lelouch.
* Misa Amane from ''Manga/DeathNote'' would be a clearer example. [[KnightTemplar Light]] definitely isn't a [[VillainProtagonist Hero]]. Then again its debatable whether or not she actually counts as his [[MadLove girlfriend]].
* ''Manga/{{One Piece}}'': Depending on your subber or dub, Nico Robin is either explicitly or implied to be Crocodile's bedroom buddy. Considering she still acts similarly, and she seemed far from that close with any of the Straw Hat crew (Until the Enies Lobby arc, at least), it seems like it's more of an act she learned to put on without actually having any meaning.
* Gyokumen Koushu from ''Manga/{{Saiyuki}}'' is the diabolical mistress of the human devouring Gyu-Maoh. Also posing as a main villain throughout the plot for attempts to revive him and bring him back to power.
* Kanae from ''Anime/RevolutionaryGirlUtena''. ''Heavily'' deconstructed: her parents barely cares about her [[spoiler: and her mom cavorts with her fiance]], it's clear that Akio is only engaged to her to gain control of Ohtori, she's shown as incredibly nervous about their relationship and her dealings with his ''very'' odd younger sister Anthy, [[spoiler: she cracks BADLY once given enough prodding by [[ManipulativeBastard Mikage]] and [[CreepyChild Mamiya]]]], and ultimately [[spoiler: it's implied that Akio and Anthy are slowly poisoning her.]]
* [[PrincessClassic Princess Charlotte]] from ''{{Manga/Berserk}}'' is [[SatelliteLoveInterest head over heels]] [[LoveAtFirstSight in love]] with Griffith, who turns into the series BigBad in an [[MoralEventHorizon EPIC WAY]]. Yet [[NaiveEverygirl she still remains in the dark]] about all of the [[HorribleJudgeOfCharacter horrific actions he has done]] as well as his true nature. While she's not a big plot device in the story, Charlotte is still of importance to Griffith - not so much as a love interest, but as a MealTicket to the throne of Midland. And holy shit, [[BreakTheCutie does the story break her]].
* Kriem is this for Jake Martinez in ''Anime/TigerAndBunny''. She believes in his cause (that is, [[DifferentlyPoweredIndividuals NEXT]] supremacy) and has a power that allows her to help him actively. Bonus points for having a similar visual motif to [[WesternAnimation/BatmanTheAnimatedSeries Harley Quinn]].

[[folder:Comic Books]]
* Harley Quinn from ''Franchise/{{Batman}}'' is in an [[MadLove abusive relationship]] with the Joker. It's a connection she can never quite shake off even when Poison Ivy shows her she can be a supervillain without him, and Batman shows her she doesn't have to be a supervillain at all. In fact, it seems that every time Harley isn't Joker's Dark Mistress, [[LesYay she's Ivy's]]. In the {{DCAU}} it's only after [[spoiler:Joker dies]] that she's finally able to get out of it.
* ''Franchise/SpiderMan''
** Shriek from Spidey's RoguesGallery is this to her AxeCrazy lover Carnage, even though she has more depth than the usual type.
** Another example comes from Doc Ock and his lover Stunner.
** And Norman Osborn and Lily Hollister0
* In ''ComicBook/CaptainAmerica'', there was the relationship between Mother Night and the ComicBook/RedSkull. The Skull being who he is, was horribly abusive to her even though she was completely loyal to him.
* SelfDemonstrating/{{Thanos}}'s love interest is the AnthropomorphicPersonification of [[TheGrimReaper Death]], though [[AboveGoodAndEvil she isn't a villain]].

* Miss Tessmacher and Kitty Kowalski from the ''Film/{{Superman}}'' movies.
** To Lex Luthor, not each other.
* Viper from ''Film/{{Doomsday}}'', her death making Sol even more AxCrazy.
* Mirage from ''WesternAnimation/TheIncredibles''. Does a HeelFaceTurn.
* In ''Film/GIJoeTheRiseOfCobra'' it's clear Destro wants or even sees {{The Baroness}} as this, but she's having none of it.
* Vulnavia in the ''[[Film/TheAbominableDrPhibes Doctor Phibes]]'' movies. Although Phibes (Creator/VincentPrice) isn't really in love with her (he's [[{{Necromantic}} pining for his dead wife]]), she clearly fills this role.
* In ''Film/{{Madhouse}}'', film star Paul Toombes (VincentPrice) plays a character named Dr. Death. Paul is annoyed when the producer insists on giving Dr. Death a pretty assistant, and even more annoyed at how unprofessional the actress (who happens to be sleeping with producer) is.
* In ''Film/TheBigHeat'', TheDragon's girlfriend starts out as the ditzy type, ignoring her boyfriend's vicious tendencies. Until he turns on her, that is.
* Cara Carozza from ''Film/DrMabuseTheGambler'', but she isn't just a mistress for eponymous Dr. Mabuse, but also is his henchwoman, and resident [[TheVamp vamp]].

* Bellatrix Lestrange from ''Literature/HarryPotter'' very clearly wishes she was Voldemort's mistress, but Voldemort really doesn't have time for that kind of nonsense. Bellatrix is married, with her husband [[SatelliteCharacter being mentioned only briefly]] and [[Film/HarryPotter the movies]] cutting him out entirely, but she probably wouldn't mind cheating on him, being evil and all, especially since WordOfGod is that it's a loveless marriage.
* Irma in ''Literature/BulldogDrummond'' is probably this, although she doesn't seem to actually do anything except lounge about on the villain's sofa being glamorous.
* ''LeftBehind'': When Hattie Durham is introduced to BigBad Carpathia, she's extremely enamored of him. She kind of sours on him when he has her put in a women's prison after she gets pregnant (with his child).

* In ''Series/DoctorWho'', Lucy Saxon is an unusual example. She's not just The Master's companion and girlfriend. She's his ''wife''. She insists that she's to stand by him for better or for worse at first, even though he's evil. Later, their relationship becomes more empty. Eventually it becomes clear that the Master doesn't care about her, and even becomes emotionally, physically, and even (it is strongly implied) sexually abusive. By the end, she's well past blind, doe-eyed admiration. In fact, sometimes it seems she ''loathes'' him for how he's broken her spirit. So it's not suprising when [[spoiler: she fatally shoots him, while giving a vacant look.]]
* ''Series/{{Heroes}}'' featured Danko's mistress, who didn't seem to know but who broke it off with him when she found out what a complete psycho he is.
* Harmony in ''Series/BuffyTheVampireSlayer'' took a turn as this after becoming a vampire, dating Spike. She was pretty much TheLoad to his group, and she eventually broke up with him for treating her as an annoying nuisance, but got back together with him several times. Her attempts to go [[BigBadWannabe solo as a villain]] were feeble enough that she eventually got an office job instead.
* Stefan and Damon were the male versions of this for Katherine when they were human in ''Series/TheVampireDiaries''
* Reverend Steve Newlin becomes this to EvilOverlord Russell Edgington in Season 5 of ''TrueBlood''
* GenderFlipped on ''Series/{{Merlin}}'', in which Morgana was calling the shots, and Agravaine was her thoroughly whipped gofer.

* Polly Peachum in ''Theatre/TheThreepennyOpera''. Interestingly, she's the main character, and spends much of the play (and the novel) wondering how she got into this situation. It's essentially Marxist commentary on the inability of young women to realize they can live independently of men, and to realize that there's other ways of being financially secure than (a) a criminal life or (b) a life as a sex object. (Later on in the play, Lucy is a straighter example of the trope. She's replaced by Fanny in the novel.)

* Sarevok in ''Videogame/BaldursGate'' has Tamoko, who shows up as the penultimate battle in the game. She can be talked out of it, but canonically she dies during the fight.
* A ''very'' rare gender-flipped version of the trope is seen in ''VideoGame/FinalFantasyVIII'': Seifer's entire goal in life is to be a sorceress' Knight (protector/henchman/plaything). He ends up being lured in by the villainness almost instantly, being reduced to her lackey for the rest of the plot. Whether or not there's a sexual element to it is left unexplored. Said sorceress is also his [[spoiler: [[WifeHusbandry foster mother]]. [[BrainwashedAndCrazy Or so it seems.]]]]
* Both ''VideoGame/{{Overlord}}'' games play this trope very straight, with the evil player character getting the chance to actually choose between several mistresses who pledge themselves to you, ranging from relatively normal women with inexplicable crushes on you, to extremely narcissistic yet beautiful women who enjoy the power and attention.
* ''Franchise/FireEmblem''
** In ''[[VideoGame/FireEmblemTellius Radiant Dawn]]'', Almedha is revealed as the Dark Mistress to the deceased BigBad of ''Path of Radiance'', Ashnard. Fits perfectly in that they were never married, though really she wasn't "together" with him long, as after their child was born and [[spoiler: she lost her powers, he claimed to hold that child hostage to keep her contained, despite the fact that he dumped the child as an orphan long ago. Her son's identity factors heavily into the plot.]]
** Princess Ishtar of the [[VideoGame/FireEmblemJugdral Jugdral series]]. As the fiancee of the evil Prince Julius, she fights the protagonists despite a case of [[MyMasterRightORWrong My Lover Right or Wrong]] and partially knowing Julius, despite caring for her in his {{yandere}} ways, is using her.
* ''VideoGame/{{Borderlands 2}}'' has Nisha, the girlfriend of Handsome Jack and a tyrant who rules Lynchwood with an iron fist.
* ''VideoGame/{{BioshockInfinite}}'': Lady Comstock, at first. She took on a new philosophy based on Comstock's religion, where sins are basically raw divinity and must be tempered into virtues. Despite her insane husband planning a campaign of city-razing. It took a while, but eventually the hypocrisy got to her and she called her husband out; BIG mistake.
* ''VideoGame/TalesOfTheAbyss'' plays this straight in one case and subverts it in another. The straight example is a teenage version in the game's backstory, where [[spoiler:the original Ion]] had Arietta. She was utterly devoted to him, even though he was a NietzscheWannabe with a complete LackOfEmpathy. The subversion is in the main game, where it seems like Legretta is this (specifically the LadyMacbeth kind, since she truly believes in her love's ideals and does whatever she can to further them) but the BigBad is ObliviousToLove.
** More to the point, Legretta only loves the BigBad BecauseDestinySaysSo. The Score determined she would fall in love with him; she knows this (and also that he's incapable of loving her back), and hates that she has no control over whom she loves.
* Excella Gionne, from ''VideoGame/ResidentEvil5''. The CEO of a major multinational corporation, she is a valid threat in her own right and overlaps with TheBaroness. Unfortunately for her, she made the mistake of attaching herself to [[BigBad Wesker]] and believes that they will rule the world together. The moment she's no longer useful to him, he deals with her [[ChronicBackstabbingDisorder in his usual fashion]].

* Alice Evanson in ''Webcomic/EvilPlan''. As the number two to supervillain Dr. Kinesis, their relationship seemed pretty platonic [[spoiler: until he literally took her home to meet the parents]].
* In ''TheDreamer'', Betsy Loring is Gen. Howe's mistress.

* In the Literature/WhateleyUniverse, Gizmatic's wife, the mother of Jobe Wilkins. Whenever Jobe meets a particularly ditzy girl, he may tell her she reminds him of his mother.

* Although prominent in many Batman comics today, it was in ''WesternAnimation/BatmanTheAnimatedSeries'' that Harley Quinn was introduced as Joker's girlfriend/henchman in an abusive relationship.
* Doctor Girlfriend from ''WesternAnimation/TheVentureBrothers'' is a supervillain in her own right, but because she doesn't have any gimmick to theme herself around, she wear a ritzy Jackie Kennedy wardrobe and defines her acts of villainy in relation to her romantic partner, The Monarch. Toward the end of the first season, she dumps him for Phantom Limb, and we see how ineffectual The Monarch is without Doctor Girlfriend around as the voice of reason. Dr. Girlfriend doesn't fare much better either, as Phantom Limb reminds her of why she left him in the first place: Limb is a high-class bore who simply wishes to have her prance around his mansion in skimpy outfits, as opposed to the Monarch, who treasures her intelligence as well as her being "heat incarnate". With the Monarch, she's second-in-command; with Phantom Limb, she serves drinks to house guests.
* On ''WesternAnimation/{{Gargoyles}},'' Fox starts out as this to Xanatos, but their relationship quickly evolves into more of an UnholyMatrimony. Their love for each other (and eventually their new baby, Alexander) is a major aspect of their eventual [[HeelFaceTurn Heel Face]] ''[[HeelFaceTurn Half]]'' [[HeelFaceTurn Turn]] into an AntiVillain couple.
* Perhaps meant to be parodied on ''WesternAnimation/PhineasAndFerb,'' where MadScientist Dr. Doofenshmirtz ''tries'' to get a girlfriend, but it never works out, even when he once met a girl [[UnholyMatrimony as evil as he is]]. He's also divorced [[MadScientistsBeautifulDaughter with a child]], though his ex-wife apparently never found out what he did for a living.
* ''WesternAnimation/TheFairlyOddparents'': [[EvilTwin Anti-Cosmo]] has Anti-Wanda. It's a slight variation, as the two ''are'' explicitly married.
* In ''WesternAnimation/SpongebobSquarepants'', [[DesignatedEvil Plankton]] has a computerized wife named Karen, who serves primarily as a voice of sense he never listens to.
* Averted in ''WesternAnimation/AvatarTheLastAirbender''. Azula may be a brilliant [[TheChessmaster chessmaster]] and a highly skilled {{Manipulative B|astard}}itch, but she is too unfamiliar with ''everyday'' social skills to form a relationship, so much that the one guy who could have been closer to her was driven away by her loud declaration of WeCanRuleTogether.
** Toyed with in the relationship between Zuko and Mai though. He's former main antagonist (on the cusp of a HeelFaceTurn), and she's the DarkActionGirl who came along on the villainous ride because she was bored and had nothing else to do. In the end though, she is one of the few positive things Zuko has to turn his back on when he leaves the Fire Nation. They even share a cheesy scene where they both agree how they hate just about everything...except each other.
* ''WesternAnimation/CaptainPlanetAndThePlaneteers'' has a {{Gender Flip}}ped example, sort of--female MadScientist Dr. Blight, whose seems to be positively flirting with her computerized [[TheDragon Dragon]], MAL, in many episodes. (They often call each other "MAL baby" and "Doctor Dearest"...)
* ''WesternAnimation/TheLegendOfKorra'':
** [[BombThrowingAnarchists The Red Lotus]] is led by [[WarriorPoet Zaheer]], while [[HavingABlast P'Li]] is his girlfriend. The two clearly care about each other, especially since [[spoiler:her death was enough to eliminate his last earthly tether and activate his ability to fly]].
** GenderFlipped in the final season: [[TheConqueror Kuvira]] is the BigBad, while [[AntagonisticOffspring Bataar Jr.]] is her fiancÚ and devoted second-in-command.
