* Although they're very much one in canon already, it shows with Han and Leia in ''[[https://www.fanfiction.net/s/7034896/1/ The Princess And The Pirate]]''. Han, Leia and Luke have ended up captured. Han's already been dragged off and severely beaten once. He's got assorted fractures, bruises, internal injuries and a high fever. But the moment some of the guards start turning their attention to Leia, Han's on his feet, giving them a DeathGlare and warning them that they're dead if they touch her. They do realize that he means business, even in his condition. Later, when they try dragging Han off again, Leia unleashes on them with Force power, because there's no way she's going to let her husband get tortured some more.

* Asuka and Shinji in ''Fanfic/NeonGenesisEvangelionGenocide'' are a couple and when they're together, they fight better and harder. When [[EldritchAbomination Samael]] fought both, it defeated Asuka, but when it was about to crush Shinji, Asuka went berserker and killed Samael.

* ''Fanfic/TheKingNobodyWanted:'' In an AdaptationalSexuality moment, Tytos recalls that his long-ago opponents Maelys Blackfyre and Derrick Fossoway were lovers, and both men were ''very'' formidable adversaries on the battlefield.
--> '''Tytos:''' They were boon and close companions, who kept a single tent between them. When Ser Derrick was called on to surrender [after Maelys died in battle], he declared, if I remember correctly, that we had slain his heart, and he would not be still until the rest of him followed.

* In the ''ComicBook/{{Supergirl}}'' fanfic ''Fanfic/HellsisterTrilogy'', ComicBook/{{Legion Of Super-Heroes}} members Kara Zor-El and Dev-Em get together during the story as fighting the minions of Mordru and Darkseid.

* In ''Fanfic/AAMLDiamondAndPearlVersion'', Ash and Misty swiftly become this after Misty rejoins Ash during his travels in Sinnoh, with the two developing a comfortable routine working together in double battles; their common team-ups either call on Charizard and Gyarados when facing opponents they need to overwhelm with raw power or Grotle and Vaporeon when they need a less direct approach, the first two being their powerhouses while Grotle and Vaporeon represent ForceAndFinesse.

[[AC:Manga/ToLoveRu]]
* ''[[https://www.fanfiction.net/s/10223400/1/To-Love-DEATH To-Love-Death]]'' has Rito and Yui fighting to survive against a zombie invasion. In its sequel, ''[[https://www.fanfiction.net/s/11591414/1/To-Love-CARNAGE To-Love-Carnage]],'' they get even.

[[AC:WebAnimation/{{RWBY}}]]
* [[WorldOfBadass Pretty much every single romantic relationship]] in ''Fanfic/RubyAndNora''.

[[AC:Anime/NeonGenesisEvangelion]]
* ''Fanfic/AdviceAndTrust'': [[TheHero Shinji]] and [[{{Tsundere}} Asuka]], natch. And given the nature of Evas, they're not merely more competent as a result, but more powerful as well.
* ''Fanfic/TheChildOfLove'': It took a good while for them to open up to each other, but Shinji and Asuka got together and kept fighting giant monsters together. In chapter 3 it is not until Asuka rushes in the battlefield that the team gains the upper hand. In chapter 7 she does not fight directly due to her pregnancy, but she provides tactical support. After giving birth she and Shinji fight in tandem.
* ''Fanfic/ACrownOfStars'': Shinji and Asuka. Their numerous battles together in the past are mentioned. Moreover, Asuka's new HumongousMecha is a two-seater, allowing Shinji and Asuka sitting together in the cockpit.
-->''He smiled at her in the comm window. "You said it, Asuka. You finally said it."\\
She blinked at him. "Said what?"\\
"'I love you.'"\\
Asuka stared blankly at him for a second before it sank in. Her eyes widened. "Well… scheiße…" she said eventually. "So much for talking about it tonight in more romantic surroundings. When I said 'right before a battle isn't exactly how or where I want to talk about this', I did mean it."\\
Shinji's smile got bigger. "Somehow, right before a battle for our lives seems fitting for us."''
* ''Fanfic/DoingItRightThisTime'': After returning to the past Shinji, Asuka and Rei are working towards becoming a battle [[UsefulNotes/{{Polyamory}} triad]].
* ''Manga/{{Evangelion 303}}'':
** Shinji and Asuka (reinforced since their [[spoiler:engagement]]). Misato even commented that both are hyper-aggressive.
** Kaworu and Saburo when they were dating.
* ''Fanfic/GhostsOfEvangelion'': Shinji and Asuka are one during the War. Thirty years after the conflict their experience fighting together still helps them beat games together.
* ''Fanfic/{{HERZ}}'': Shinji and Asuka, although due to Unit 02 getting repaired they are not seen battling in tandem until [[spoiler:the FinalBattle when they sortie together to fight the SEELE forces]].
* ''Fanfic/HigherLearning'': As their relationship strengthens throughout the story, Shinji and Asuka become an efficient fighting duo.
* Asuka and Shinji in ''Fanfic/NeonGenesisEvangelionGenocide'' are a couple and when they're together, they fight better and harder. When [[EldritchAbomination Samael]] fought both, it defeated Asuka, but when it was about to crush Shinji, Asuka went berserker and killed Samael. They also fought [[spoiler:the MP-Evas and the final HumanoidAbomination]] back-to-back.
* In ''Fanfic/NeonMetathesisEvangelion'', that is Asuka ''and Rei''. Not so much Shinji. Shinji never moves past his loathing for piloting and would prefer to just stay the TeamChef and the [[OneTrueThreesome triad's]] moral support.
* ''Fanfic/OnceMoreWithFeeling'': Asuka and Shinji started on the path to becoming one as of battling the Sixth and Seventh Angel. They fought together and performed spectacularly.
-->Not that Shinji could begrudge Asuka her grand entrance. Perhaps she hadn't exactly covered herself in glory today… but by the same token; he couldn't have done it without her. Not for the first time, he smiled slightly at that thought, working side by side with her again; Asuka the burning sword, Asuka the raging, unquenchable firestorm-
* ''Fanfic/TheOneILoveIs'': Shinji and Asuka. Due to living, working and fighting together, they started to like each other and became extremely close. This closeness kicks the plot off when Rei realizes Shinji is falling for Asuka and decides to pursue him actively.
* ''Fanfic/ScarTissue'': Shinji and Asuka. During the Angel War they battled giant alien monsters together despite of their fights and arguments. In chapter 17 Asuka's HumongousMecha is modified so that Shinji and she can pilot in tandem and fight together. Shinji also tells her he will not leave her to fight alone again.
* ''Fanfic/TheSecondTry'': Shinji and Asuka, even more than in the original series now that they are serious about fighting, have gotten over their crippling psychological and emotional problems, and want to support and help each other. It even is noted by [[spoiler:Kaworu]].
** In the [[spoiler:second-to-last]] episode:
-->'''Asuka (to Shinji):''' I'll handle them. These guys aren't the real problem after all. Just take care of my cable, okay?\\
'''Shinji (smiling weakly and nodding):''' Of course.
** And later in the same episode:
-->[[spoiler:'''General:''']] Concentrate all fire on that power cable!\\
[[spoiler:'''Comm-Officer''':]] It's no use, Sir! Purple's guarding it!

[[AC:WesternAnimation/TotalDrama]]
* ''Fanfic/FuzzyMemories'' has [[PintsizedPowerhouse Tempest]] and [[UnluckyEverydude Zetsu]], who have a strong and healthy relationship, but nonetheless are both badasses in their own right, and by the special of the series, the two are now on-par enough that the latter can actually keep up with his girlfriend in terms of hunting and fighting, despite not being nearly as close to her strength.

* The ''Fanfic/PonyPOVSeries'' has the [[BadFuture Dark World versions of]] [[GeniusBruiser Spike]] and [[WarriorTherapist Rarity]], once Rarity finally returns his affections and they become an OfficialCouple. (One of the few good things to come out of Discord's reign was Spike reaching his adult age in Rarity's lifetime.)
** Cadance and Shining Armor are naturally this trope, as in canon.
** Gag and Garnet have their moments, but since they're in a unit, it isn't as noticeable as other examples.
** During the FinalBattle of the Age of Myths (G1), Katrina and Rep (now HappilyMarried) are one of these when GondorCallsForAid. [[spoiler:They kill Ashley, one of Hydia's dangerous family, by [[DisneyVillainDeath sending her falling to her death]] with a FastBallSpecial.]]

In the next chapter Eleya catches them meeting up in Ten Forward, and [=McMillan=] gives K'lak "a peck on the cheek that looks a lot more than just friendly." Eleya alludes to moving [=McMillan=] to a different supervisor.
* Khan and his lover, Victoria, are this in the ''Film/StarTrek2009'' fanfic ''[[https://www.fanfiction.net/s/9694363/1/Safe-and-Sound Safe and Sound]]''. During the Eugenics Wars they apparently marched into the Taj Mahal, and after the ensuing battle (during which Victoria killed thirty armed guards with her bare hands while saving Khan from them; it's not mentioned how many Khan killed) they marched back out again having claimed the building as theirs.

[[AC:Literature/{{Discworld}}]]
* In ''Fanfic/WhyandWere'', Assassin Johanna Smith-Rhodes provides the muscle and fighting ability; wizard Ponder Stibbons is the magical half of the relationship.

[[AC:WesternAnimation/KimPossible]]
* Kim and Shego in ''Fanfic/AtTheCenterfoldOfTheStorm''. Unlike in most [[PortmanteauCoupleName Kigo]] fics that focus on the two settling down and starting a family, Kim and Shego decide to continue in the Secret Agent/Super Hero line of work, such as battling volcanoes, fighting HumongousMecha on foot and taking on the entire criminal underworld.

[[AC:Franchise/SuperSentai/Franchise/PowerRangers]]
* Red Ranger Sean O'Callahan and Yellow Ranger Maria Aparicio of ''FanFic/PowerRangersGPX'' fit this bill once they start dating. They even get the occasional BackToBackBadasses moments.

[[AC:Franchise/StarWars]]
* Although they're very much one in canon already, it shows with Han and Leia in ''[[https://www.fanfiction.net/s/7034896/1/ The Princess And The Pirate]]''. Han, Leia and Luke have ended up captured. Han's already been dragged off and severely beaten once. He's got assorted fractures, bruises, internal injuries and a high fever. But the moment some of the guards start turning their attention to Leia, Han's on his feet, giving them a DeathGlare and warning them that they're dead if they touch her. They do realize that he means business, even in his condition. Later, when they try dragging Han off again, Leia unleashes on them with Force power, because there's no way she's going to let her husband get tortured some more.
* ''Fanfic/BloodAndHonor'': Sanguis and Quinn, though they go back and forth on the "couple" part for about half the story due to Quinn's personal issues. Eventually they end up together on and off the battlefield. Sanguis typically gets in close with her lightsabers to take out the biggest threat while Quinn uses his brains and blaster to wreak havoc from a distance.

[[AC:LightNovel/InfiniteStratos]]
* In ''FanFic/InfiniteStratosToTheOtherEndOfTheWorld'', there are quite some battle couples. Hackers are trained as BashBrothers, but in later chapters, the hackers discover they can work pretty well with Infinite Stratos pilots as well. An example that is most prominent are Kerlongsj and Chifuyu fight [[BackToBackBadass as one]] and they take out an entire army with just the two of them. Due to their history, they're quite good at it, despite the huge difference in style, weapons and special powers.

[[AC:Series/StargateSG1]]
* In ''Fanfic/WhatYouAlreadyKnow'', Daniel Jackson and Sam Carter have no problem fighting alongside each other as their relationship unfolds, with Daniel's psychic powers mixing well with Sam's military experience, although they have to be granted special dispensation to continue their relationship after Sam is promoted to team leader.

[[AC:Franchise/DragonAge]]
* [[VideoGame/DragonAgeII Varric and Bethany]] gradually evolve into one of these in ''Fanfic/BeyondHeroes: Of Sunshine and Red Lyrium''. It becomes [[EveryoneCanSeeIt obvious enough that the companions start remarking on it]].
* Both of the main couples in the ''Fanfic/TwiceUponAnAge'' series do this a couple of times; given that it covers the events of ''VideoGame/DragonAgeInquisition'', it's par for the course. Mahanon and Cassandra get more opportunities, because Cassandra is an active party member, but Cullen and Victoria take a few turns when circumstances permit it. Dorian and the Iron Bull also fall into this occasionally, and it's indicated that so do [[spoiler:Varric and Bethany]] at least once.

[[AC:Franchise/MarvelUniverse]]

[[AC:Manga/{{Naruto}}]]
* Most couples in ''Fanfic/SonOfTheSannin'' are shown fighting side by side at one point or another ([[OfficialCouple Naruto and Hinata]] being the most prominent example), but special mention goes to Shizune and Shisui, who team up with the intent to kill Danzo [[spoiler:after he has their infant children kidnapped.]]

[[AC:WesternAnimation/MiraculousLadybug]]

[[AC:VideoGame/DevilMayCry]]

* Asuka and Shinji in ''Fanfic/NeonGenesisEvangelionGenocide'' are a couple and when they're together, they fight better and harder.

* ''Fanfic/TheBridge'' gives us, after a half dozen RelationshipUpgrade moments to go from enemies to friends to OfficialCouple, [[spoiler: Aria Blaze and Monster X when they have the final confrontation with Enjin]]. Bonus points for the story's first OfficialKiss happening right after they won.

* ''Fanfic/TotalDramaBattleOfTheGenerations'': Shawn and Jasmine. Both are strong competitors on their own, but together they help their team win three challenges in a row.
* [[VideoGame/DragonAgeII Varric and Bethany]] gradually evolve into one of these in ''Fanfic/BeyondHeroes: Of Sunshine and Red Lyrium''. It becomes obvious enough that the companions start remarking on it.

After giving birth she and Shinji fight in tandem.
* ''Fanfic/ChildOfTheStorm'' has several examples:
** Sif and Loki, after the finally get together at the end of the first book, though they don't always fight side by side, given that she's the Goddess of War (especially close-quarters-combat) and Loki's skills tend more towards skulduggery and command-and-control level sorcery.
** Uhtred and Jean-Paul become this once they get together, despite Jean-Paul's distaste for fighting - all it means is that he prefers not to fight, and that when it comes to it, he will end the fight quickly. Which, in an imaginative and exceptionally powerful speedster [[CombatPragmatist with more pragmatism than scruples]] can get ''messy.''
** Harry and Carol function as this even though they're an AnchoredShip for much of the end of the first book and the second book, up to and including a ''ridiculous'' amount of FlirtingUnderFire while fighting anything and everything from superpowered {{Renegade Russian}}s to {{Vampire Monarch}}s and {{Eldritch Abomination}}s. Ironically, at the time of writing, they haven't fought together since [[spoiler: they got together]].

* ''{{Fanfic/FuzzyMemories}}'' has [[PintsizedPowerhouse Tempest]] and [[UnluckyEverydude Zetsu]], who have a strong and healthy relationship, but nonetheless are both badasses in their own right, and by the special of the series, the two are now on-par enough that the latter can actually keep up with girlfriend in terms of hunting and fighting, despite not being nearly as close to her strength.
