Best Her to Bed Her

""So, the only man that can have you is one who's already tried to kill you. That's logic.""

- Kalidor, Red Sonja

Defeat Means Friendship with an instant Relationship Upgrade.

A woman that can/will only fall in love with a man that can "conquer" her. This can be either someone who bests her in combat (this obviously only applies to warrior women), or a man who takes charge and shows her that he is the one who is making decisions. Can cross over into Victim Falls For Rapist if she's not consciously aware that this is how she feels. Remember, there must be some rule or custom for this trope to apply. Falling in love with your opponent after he defeats/stands up to you is another trope.

Compare All Amazons Want Hercules. See also Slap Slap Kiss. See also Sex Face Turn and High Heel Face Turn. See also Red Sonja (the character's page). Contrast Love At First Punch, which lacks the explict requirement either by the character themselves or their society.

Anime and Manga

 * Shampoo and the rest of her Amazon tribe in Ranma 1/2.
 * Also indirectly (and to her immense annoyance) Akane, after Kuno proclaimed that only he who could defeat her in combat was worthy of dating her. Cue the morning routine in which half the student body at Furinkan High (the male half) went out to fight her.
 * Amusingly enough, Kuno applies this trope to himself, claiming that if the Pigtailed Girl (Ranma) can defeat him, he shall allow her to date with him. (And if he wins, he gets to date her. Convenient, in a Heads I Win, Tails You Lose sort of way.)
 * Maybe something was lost in translation, because that sounds a bit like a dominance thing-maybe the one who wins the fight gets to wear the pants in the relationship?
 * Another variation is Akari Unryuu, whose grandfather wanted her to only marry a boy strong enough to defeat her giant sumo pig.
 * Miriya in Macross/Robotech is a borderline case. She fell in love with Max after he beat her, but there was never an explicit "rule" about it. (There was to be a female pilot in the never-produced Robotech II: The Sentinels who idolised Miriya and in an in-universe version of Misaimed Fandom vowed only to marry a man who beat her.)
 * Macross 7 arguably subverts this, as Max and Miriya have grown estranged from one another and Miriya is questioning whether marrying him was such a good idea.
 * It's rather un-subverted by the fact that they get back together in the end.
 * It was never subverted: the series strongly hints that Max and Milia grew apart because they couldn't mentally deal with normal married life, not for lack of love. Max and Milia are only good at fighting and sex (the pair had six children together, the second almost killing Milia during childbirth). Living together in harmony outside of those two activities is a major challenge for them.
 * Inverted in Steel Fist Riku: After she beats Chikara Toudou, Riku learns that he is now forbidden from setting foot on his family's property until he either defeats or marries her.
 * A less extreme version of this trope can be found in Bakuman｡, where Iwase, the smartest girl in school, believes that she and Takagi are now a couple when he gets better grades than her. Too bad he thinks she was just making a friendly competition out of it.
 * As of recent chapters.
 * In Mahou Sensei Negima it was recently revealed that Ku Fei has imposed this policy on herself.
 * Note that Ku Fei doesn't require that the combat actually take place, she can tell that Negi could defeat her in an actual match, and that being able to defeat her is a necessary but not sufficient criteria. She's not romantically interested in Negi. Not yet, anyway.
 * Awkward timing there, huh?
 * Kumiko pulls this trope in Gokusen to get out of an attempted arranged marriage. However her tactics only make the prospective groom fall more in love with her and determined to win the fight and her hand.
 * Somewhat for Hinagiku of Hayate the Combat Butler. Hayate has 'conquered' her, in that he's taught her how to defeat her fears (or at least the knowledge how to), but when admitting it to Ayumu, she still wants Hayate to be the one to start the romance.
 * Unfortunately she's already seemingly given up on that, having tried a few times to confess.
 * Less of giving up, more of realizing that Hayate is just that stupid.
 * Subverted in Pokémon Special. It is heavily hinted that the reason why Winona broke it off with Wallace was that having the regional champion as her boyfriend made her insecure of her own abilities.
 * The Gurren Lagann manga Guren Gakuenhen has Nia's split personality showing signs of this.
 * In the Sorcerer Hunters manga, Gateau's younger sister Eclair once vowed that she would never fall in love with any man who couldn't beat her in a fight. Since Eclair is about as strong as her brother, this disqualified most men in the world.
 * In Ne.To.Ge, Yamaji says she'll marry Imamichi if he can best her even one time in the MMORPG they play. Since he's a developer for the game (and because this is a Hentai) he wins by programming in tentacles.

Comic Books

 * The former Trope Namer here is Red Sonja, originally(-ish) from the Conan the Barbarian comics (and later a movie starring Brigitte Nielsen). Red Sonja lived with her family in a humble house in the Western Hyrkanian steppes (modern Ukraine/Russia). When she had just turned 17 years old, a group of mercenaries killed her family and burned down their house. Sonja survived but she had been brutally raped by the leader of the group, leaving her in shame. Answering her cry for revenge, the red goddess Scathach appeared to her, and instilled in her incredible skill in the handling of swords and other weapons on the condition that she would never lie with a man unless he defeated her in fair combat.
 * Peter David commented that this essentially means that the only man she can ever love is one capable of replicating the most traumatic experience of her life.
 * Conan managed to beat her in the last story of Roy Thomas's original run. He could tell she was reluctant and he had just lost Belit recently, so he didn't do anything with her.
 * At the end of the same issue, Sonja confessed her feelings for Conan and her fears of what might happen if she didn't put some distance between them.
 * Interestingly enough, in a What If? story where Wolverine became lost in time and wound up in Hyboria at the same time this story took place, Wolverine was able to beat Sonja in battle and went on to become King of Aquilonia instead of Conan, with Sonja as his queen.
 * Though Wolverine's not thrilled with the initial situation. After he beats Sonja, she basically gives up and waits to be raped. Wolverine walks away, telling her "Sorry, darlin', that ain't my style." She's both perplexed and slightly insulted so she follows him. It's only after their next meeting that he warms up to her.
 * In the movie, she and Kalidor fight to a standstill. At the end, Kalidor inverts this by saying he makes it a rule never to marry a woman unless she can beat him in a fair fight. The pair exchange a couple of sword strokes before kissing.
 * In issue 15 of the current series, she and two friends take on a god--a weakened god, but still a quasi-deity at least. He quite naturally trounces them. Whether that counts as a fair fight, which is what has to be waged for it to work, is somewhat moot:
 * This was further spelled out in issue #31, where it is revealed that Sonja did share a romantic, but non-physical relationship with a king who hired her as his bodyguard and grew to want her as his queen. Sonja refused, fearful of killing the man she loved if he pressed the issue of being able to consummate their love and challenged her to single combat. Seeking guidance from her goddess, Sonja was told that she could abandon her oath but that she would lose the superior skills she had been blessed with. Deciding this was acceptable, Sonja went to the King's bed chamber to tell him her decision, just as a group of assassins with magical weapons showed up. Sonja was able to repel the assassins but knew the only reason she was able to do so was because of her blessed skills. Her sense of responsibility to hold to her oath to fight evil at the expense of a normal life held and she resigned her post the next day.
 * It's worth noting that the traditional interpretation of Sonja's blessing/curse may have missed the mark. The reality appears to be that Goddess granted Sonja powers that she could only lose by voluntarily lying with a man, like the traditional oath of chastity. The "unless he defeats you in combat" may simply be a rape exception, so that Sonja doesn't lose her powers if she is defeated and taken advantage of. After all, she was given her powers in the first place to kill a rapist, so it would be a good idea to make sure she wouldn't be depowered & could get revenge again if it happened again. Of course, Scathach asking for an oath of chastity in the first place is a case of Did Not Do the Research, since the goddess in question is an aspect of the Morrigan, a war goddess known for, among other forms of Karmic Justice and Kick the Dog, raping male heroes and villains (with or without offering a Sadistic Choice between sex or death first) as punishment or a symbol of the horrors of war.
 * Parodied by the character Blue Opal in the Phil Foglio comic XXXenophile, for whom this was more a curse than an oath. After the sexually-frustrated warrior out-drinks and out-fights every man in the bar, the only one left is a meek man who invites her to play a strategy game with him. The curse is lifted after he beats her at the game--which, as they realize later, has a name that translates as "Battle". Joyful sex ensues.
 * Subverted in furry parody comic series, Red Shetland. At one point, the titular character and a chivalrous and handsome stag knight end sharing blankets on a wintry night in a cave. The setting created too much temptation for Red to resist and she has passionate sex with her new lover. Later, Red is convinced that her goddess has removed her boons because of this and is despondent, until the Stag proves to her that she has lost nothing once she regains her confidence.
 * Viciously parodied in Wonder Woman vol.3 #24, where the producers of a Wonder Woman movie have her make this vow, and get defeated by Hercules. The real Wonder Woman is not impressed. Not least because in the DCU, Hercules raped Wonder Woman's mother.
 * Earlier, Power of Shazam had an inversion: Billy Batson has a dream about arm-wrestling Wonder Woman in which he throws the match because the Wisdom of Solomon tells him she needs to defeat him before they can "get together".
 * Frank Miller's The Dark Knight Strikes Again had Wonder Woman imply that she hooked up with Superman, after he threw her on the ground and made her his own. Miller takes it up a notch in All Star Batman and Robin with Superman knocking Wonder Woman on to the ground, Wonder Woman calling him a bastard, and then the two start making out.
 * She-Beard from Seaguy.
 * Parodied in Cerebus as Red Sophia. Her father hires Cerebus to torture the man who besmirched her honor. During the journey her logorrhea is too much, they fight, he wins, she pledges service. The eventual torture is forcing the blackguard (who saw her naked) to marry Sophia. Years later she marries Cerebus.

Folk Lore

 * According to Marco Polo, Aiyaruk, the daughter of a nephew of Kublai Khan, said that she'd only marry a man who could defeat her in a wrestling match. She never did find a husband. Demanding that every suitor bring her one hundred horses that would be forfeit if he lost, Aiyaruk came to own ten thousand steeds. Eventually, a handsome and especially strong prince came and offered a thousand horses instead of a hundred, to show his confidence. Aiyaruk's parents begged her to let him win, but she refused. In the Hollywood version, he'd probably have been the one to get the girl -- but according to Polo's account, after an especially long and difficult match, she was able to defeat him, too. Aiyaruk never did find her match, and instead became a skilled warrior (which was not unheard of amongst Mongolian women, regardless of the accuracy of Polo's specific account).
 * Nearly inverted by the Scythians, a nomadic civilization whose women were warriors. Greek accounts would have it that before they could get married, Scythian women had to defeat three men in combat. (However, not full inversion as they married others of their tribe rather than the defeated men, who were often dead.)

Film

 * In Curse Of The Ring, Queen Brunhilde wears a magical belt that makes her stronger than just about any man. She will only wed the man who can outpower her or best her in combat. There is one such man, but he is not interested in her due to a spell put on him. But he is the only one she wants, and is after his love.

Literature

 * In the Nibelungenlied, a 12th-13th century German verse epic, the Icelandic queen Brunhilde declared that she would only marry the man who could defeat her in three contests of strength, one of them direct combat with her. Only one man alive was capable of this, the protagonist Siegfried; however, Siegfried had his eye on Kriemhild, sister of King Gunther, and so he agreed to aid Gunther using his incredible strength and magical artifacts, one of which let him become invisible so he could create the illusion that Gunther won the contests while Siegfried did the hard work.
 * Chaucer's Wife of Bath describes having several husbands whom she doesn't seem to care for in the slightest; that is, until she marries Jankyn, the first man who seems to have an ounce of power over her.
 * Of course, given the content of the Wife of Bath's tale and the fact that  this may be more of a desire for a challenge than a desire to be "conquered."
 * Bradamante, the daughter of Duke Aymon in Ariosto's epic Orlando Furioso, escapes the specter of arranged marriage by getting Emperor Charlemagne to promise that she won't have to marry any man who can't endure a duel with her from dawn to dusk. Her motivation for this is that she's fallen for a Saracen knight named Ruggiero and been tasked by Merlin's ghost with converting him and founding a lineage of great Italians.
 * Britomart (an Expy of Bradamante) in Edmund Spenser's poem The Faerie Queene is another example, with pretty much the same vow as Red Sonja's if for completely different reasons. She is an allegorical figure of the virgin Knight of Chastity.
 * The wildling women of A Song of Ice and Fire won't accept husbands who aren't tough enough to kidnap them.
 * The Marat in the Codex Alera are a subversion. Marat women do give potential suitors a challenge that they must complete to win their affection. However, the challenge isn't necessarily against the woman herself, and either way the woman chooses the challenge. This means, as Tavi notes, if the woman doesn't fancy that particular suitor, she need only choose a contest he's likely to fail at. Kitai's challenge to Tavi: Defeat the Big Bad.
 * The ancient chinese tale Hua Guan Suo Zhuan speaks of a Bao Sanniang, a young girl who was both immensely beautiful, and immensely strong. With countless suitors, she declared that she'd only marry the one who could beat her in a duel, and proceeded to beat up every last man who came for her hand. Eventually, Guan Suo - third son of the incomparable Guan 'The God Of War' Yu - heard of this, and went to challenge her. He beat her, and she instantly fell in love with him. (By all accounts, he was quite the Bishonen, and known to wear flowers in his hair even upon the battlefield, so that probably helped too...) From then on, she followed him everywhere, and even fought alongside him in his remaining campaigns.
 * There is some debate as to whether Bao Sanniang is a wholly fictional character, or a romantization/dramatization of a historical individual, mind.

Live Action TV

 * Saffron from Firefly tried to con Mal at the end of the episode "Our Mrs. Reynolds" by pretending to be this type, but Mal didn't fall for it and responded with a Dramatic Gun Cock instead.
 * The Quantum Leap episode "How the Tess Was Won".
 * In Dark Kingdom The Dragon King (a.k.a. The Ring of the Nibelungs) Kristanna Loken plays Brunhilde the Queen who will lose all her strength if she marries a man who has not defeated her in battle.

Myth and Legend

 * Older Than Feudalism: This happens at least a few times in Greek Mythology:
 * Amazon Queen Hippolyta and Heracles. All Amazons Want Hercules, after all.
 * Atalanta, who would only marry a man who could defeat her in a foot race. The losers were executed. Eventually, Aphrodite got sick of Atalanta's attitude and gave the next competitor three golden apples with which to cheat. Every time Atalanta got ahead, he threw one out in front of her and broke for the lead while she was distracted, giving him the win.
 * The idea for Red Sonja herself was taken from Aoife of Irish mythology via a William Butler Yeats play, though as noted there are examples considerably older with this.

Tabletop Games

 * A set of Dungeons and Dragons trading cards from the mid-90s included a variation, with a Lawful Good priestess who was prophecised to leave the sisterhood in order to wed a great hero, and vowed only to marry a man whose virtues exceeded her own.

Theatre

 * Shakespeare's A Midsummer Night's Dream had the Amazon Queen Hippolyta marrying Theseus, the Duke of Athens, after he defeated her forces.

Video Games

 * The first Discworld game has a Red Sonja Expy, who had the standard oath regarding laying with a man who could defeat her.
 * Later on in the game, she notes that she was finally defeated by a man who challenged her to a game of tiddlywinks. It seems her goddess didn't stipulate that she had to be defeated in armed combat. Rincewind learns of this, much to his regret, as he is REALLY good at tiddlywinks.
 * Curiously, completing the Handmaiden's romance sidequest in Knights of the Old Republic 2 requires defeating her in three unarmed duels. Where both participants are wearing underwear (the player's covers more than the Handmaiden's does, though).
 * Ditto for the sidequest with Visas, though hers is more of a Defeat Means Friendship blossoming into something more.
 * Jeanne, of World Heroes seems to be of this type, as her endings usually have her lamenting her victories as a still-single woman.
 * Uthgerd the Unbroken in Skyrim will only marry you if you can defeat her in a brawl.
 * Non-canon sidequests in Dynasty Warriors games often involve male characters needing to prove they are worthy of their love interests by defeating them.

Web Comics
"Inferno: Hey, Grimlock, ya didn't win the lottery last week.
 * In the webcomic Captain SNES, the wife of Cid from Final Fantasy IV is said to be this.
 * The unnamed Mongol warrior from Get Medieval falls hard for the alien gladiatrix Rylede after she defeats him.
 * Yatta-Ta is convinced that the title character of The Challenges of Zona is this and so far, no amount of evidence to the contrary will convince him otherwise.
 * Parodied in Insecticomics: after being beaten by Flamewar, Grimlock assumes he has to marry her. Flamewar questions the logic of this, asking if she has to marry Jazz because he once shot her in the back. Being Grimlock, he agrees, and it only gets better from there. Jazz even refers to it as a "Red Sonja-kick".

Grimlock: Then me Grimlock must marry...the LOTTERY!

Prowl: Don't encourage him, Inferno."

Web Original

 * Previous stage decoration Tardboy and his "sub" Torako from Yukari Is Free might be considered of this type.
 * A character by furry artist, Linno, falls under this trope (at least at one point). His Kangaroo babe, named "K.O." is a professional boxer, who uses both her fists and her tail to box with. Of course, this would seemingly make her quite tough to beat in an actual match; so for anyone who does beat her in a one-on-one challenge gets a very special prize. Believe it or not, there was even an adult flash game made out of it (no, this isn't made up).
 * The If I Am Ever The Heroine list (similar to the Evil Overlord List) strongly warns against agreeing to this practice.

Western Animation

 * Maxima in Superman: The Animated Series dragged Superman off to her home planet to be her mate after he defeated her in a fight. Of course, when Lobo shows up, it's "Superman who?" Note that in the comics, Maxima merely wanted Supes because his genes went well with her royal bloodline of warriors.
