Fire-Forged Friends

"There are some things you can't share without ending up liking each other, and knocking out a twelve-foot mountain troll is one of them."

"We few...we happy few. We band of brothers. For he that sheds his blood today with mine shall be my brother."

Whether hostile to each other, indifferent, or strangers, different groups must fight on the same side. All the way up to an Enemy Mine situation. Afterwards, they are no longer hostile and perhaps even actual friends. If they continue as enemies, they are Friendly Enemy.

Bonus points if:

The Power of Trust often comes into play, since they often must trust the other not to stab them In the Back.

Borderline cases when Redemption Equals Death, since the friendship could have broken up after the fighting ended. Still, expect the survivor to refuse to let the other die alone, and often a Meaningful Funeral or To Absent Friends follows, especially if it involved a long period of time and hiatuses in the actual fighting—a campaign or a war rather than a battle. May occur after Let's You and Him Fight, and lead to Lighthearted Rematch. May also lead to exchanging plot-significant objects, or just an Odd Friendship. In a military situation, when this occurs between a superior and his juniors, may lead to their speaking With Due Respect. When mistrust is manifested after this trope, Remember That You Trust Me often ensues.

Other hazardous or even mere strenuous activities that require mutual assistance, such as The Chase, can also develop a kind of this; the closer it comes to as dangerous as war, like an attempt to escape through a jungle full of man-eating beasts and other dangers, the more it will resemble it.

Overlap with Band of Brothers is considerable, but in this trope, they need never to work together again, and that one, they do not have to be friendly, just reliable.

When these fire-forged friends belong to opposite genders, expect them to take it to the next level.

Truth in Television to a very large extent, as many people who served in any military force can testify, even more so if they are war veterans. Note that if they did not actually fight in the same battles, it's Commonality Connection to learn they were both soldiers.

    Anime and Manga 
  • Bleach:
    • After being forced to team up, Ichigo Kurosaki and Uryu Ishida quickly became best friends...though Uryu refuses to admit it. He tries to insist that Ichigo is still his sworn enemy, except that his actions (and words) prove he's full of it.
    • In a flashback, Ichigo and Chad seem to be this to a degree. Ichigo was initially hostile towards Chad (questioning his Technical Pacifism and passively accusing him of lying) but turned up to save him when he was attacked (and of course refused to defend himself).
  • Nearly every hero besides Goku in Dragon Ball and Dragon Ball Z became one this way: getting defeated by Goku, spending some time getting used to his cheerful good nature, and then having to fight alongside him against a new threat. Krillin spells out this trope partway through Dragon Ball Z, arguing that despite having foreknowledge of their next threat, they should merely prepare to battle rather than make a preemptive strike, as nobody was sure whether or not Vegeta wouldn't just kill them all if he didn't have something other than "defeat Goku" on his to-do list.
  • Joseph and Caesar in JoJo's Bizarre Adventure both hated each other when they first met, and couldn't stand the idea of working together. After their first confrontation with the Pillar Men, they became close friends to the point where Caesar's final action before he dies is to retrieve the antidote to the poison inside Joseph.
  • Negi and Kotaro go through this in Mahou Sensei Negima!: they start out as enemies, have to join forces to defeat a demon, and are good friends after that.
    • Ditto Yue and Emily Sevensheep: Emily starts off as the Alpha Bitch, but opens up to Yue after Yue saves her from a Griffin Dragon.
  • One Piece: Pretty much the formula for adding onto Luffy's True Companions. He makes an offer, which they usually refuse at first. He then fights the current Big Bad by their side and afterward they usually make the decision to join his crew. Zoro, Nami, Sanji, Chopper, and Brook all joined this way, while Usopp was invited after the Big Bad was defeated and did not hesitate, and Robin invited herself.
    • Franky may be the best example of this among the Straw Hats. Initially, the dislike was mutual; Luffy (and the rest of his crew) hated Franky for beating up Usopp, and Franky wanted revenge on Luffy for blowing up the Franky House and beating up his family (in retaliation). The two put aside their differences when CP9 came into the picture, and Franky's reluctance to join the crew after the whole thing was over was mainly due to having attachments to Water 7 and his family.
    • Surprisingly, Gold Roger invokes the trope as he speaks to Vice-Admiral Garp right before he's executed. He says that they are as good as friends, given how long they've known each other, and, on this principle, trusts Garp to protect his soon-to-be-born child from the Marines. Despite the other person's initial disbelief, it works: Garp locates Roger's girlfriend Rouge, stays with her as she entrusts him with the baby before dying, and ultimately raises Roger and Rouge's child Ace alongside his own grandson Luffy.
    • A pair of slightly lesser examples are Smoker and his protégé Tashigi of the Marines. They pursued the Straw Hats to the Grand Line after they escaped Loguetown, and didn't think of them any differently than other pirates (aside from considering them more threatening than most). Then comes the Alabasta arc, where the Big Bad, Crocodile, imprisons some of the Straw Hats and Smoker in a cage and explains his Evil Plan to them. Smoker shows the first sign of this trope when they escape—he only escaping with his life because Luffy had him saved—by letting the Straw Hats go free, though it would be fair to say that that's because of his Lawful Good nature. After that, Smoker passes command to Tashigi while he informs his superiors, and she allies with the Straw Hats in order to bring Crocodile down. At the end of it all, Smoker and Tashigi still hold a grudge against the Straw Hats as pirates, but they respect them a lot more.
      • Then, after the Time Skip, we have the Punk Hazard Arc. Vice-Admiral Smoker and Captain Tashigi, now the commanders of a base filled with Ax-Crazy Marines, are waiting to intercept the Straw Hats in the New World, but when they take an unexpected detour to an island that is supposed to be deserted, they head there. They soon find out that something very fishy is going on, and are caught in the middle of it, undergoing a "Freaky Friday" Flip as one of the first fragments of trouble. Eventually, both of them end up trapped in a cage with the Straw Hats againp, (and Robin, who was The Dragon when it happened last time, lampshades it) along with the Big Bad's subordinate, Shichibukai Trafalgar Law, who had revealed himself to be a Wild Card, and watching the Evil Plan play out in front of them. When they escape, the Marines are forced into a full-blown Enemy Mine with the Straw Hats and Law, including such things as Sanji taking command of the Marine underlings and Tashigi and Zoro teaming up against The Dragon. At the end of it all, Smoker and Tashigi seem to be almost friendly with the Straw Hats, while their subordinates flat-out state that they admire them.
    • The Dressrosa arc. The number of Fire-Forged Friends forged against Donquixote Doflamingo gives rise to the Straw Hat Grand Fleet.
  • Naruto:
    • Pretty much the background of Kakashi Hatake. Back then a Drill Sergeant Nasty who isn't really in the best terms with his teammates Obito Uchiha and Rin, his strict by-the-rules persona was changed by Obito's choice to save Rin when she was kidnapped, even calling out Kakashi on his callousness. As a result, Kakashi intervenes to save Obito, and helps Obito activate his Sharingan. Unfortunately, the rescue mission ends with Obito having to protect them in a cave-in, crushing him in the process and giving his Sharingan to Kakashi. This tragic ordeal made Kakashi more lax and understanding of others, even adopting Obito's lackluster work ethic.
    • Initially, Team 7 starts out as a jumbled mess of dysfunctional relationships: Naruto hates Sasuke and has a one-sided shallow crush on Sakura, Sasuke finds both Naruto and Sakura annoying, Sakura loves Sasuke and can barely stand Naruto. Once Kakashi puts them into a situation where they're forced to work together, they start to get along and become friends, although Sasuke and Sakura still found Naruto too annoying to actually care about his problems. However, Sasuke pulls a Face–Heel Turn at the end of Part I and from then on goes through quite the Heel–Face Revolving Door. Not that it ends up mattering much, since Naruto "How can I be Hokage if I can't save one friend"/"I'll take all your hatred" Uzumaki and Sasuke "My body moved on its own"/"I've come to accept you" Uchiha exemplify this trope.
    • At times, even the bitter relationship between Naruto and the Kyuubi is like this. When Naruto is on the brink of death, the Kyuubi would willingly lend chakra to him to protect himself. However, during the War, when the real Madara appeared and attempted to summon the Kyuubi, he gave as much chakra as he could to Naruto, saying that he would rather help Naruto than be controlled by Madara.
  • Nanoha and Vita in Magical Girl Lyrical Nanoha A's, with Vita's hostility towards Nanoha decreasing drastically after they worked together to beat up the self-defense program. Fate and Signum might also count but both were shown from the start to be perfectly willing to be friends if they weren't on opposing sides.
    • During the time between A's and StrikerS, Vita became much less distant to Nanoha after she failied to protect her in the mission involving the Type IV Gadget Drones who nearly killed Nanoha.
    • Similarly, Nanoha and Arf in Season 1; Arf initially dislikes Nanoha, thinking of her as far weaker than Fate and being suspicious of her motives for reaching out to Fate. After Arf gets thrown out of the Garden of Time, she reluctantly decides to accept Nanoha's help in saving Fate. By the time Nanoha becomes friends with Fate, Arf has also come to like her.
  • In YuYu Hakusho, Kuwabara goes from being an Unknown Rival to Yuusuke to being his best friend this way after they find themselves on the same side by coincidence more than once.
    • In general the whole Urameshi Team of Yusuke, Kuwabara, Kurama and Hiei is this, especially after the Dark Tournament.
  • This is a recurring trope in Studio Ghibli works due to the rarity of actually evil antagonists:
  • Berserk: All around hardass Guts starts off hostile and cold towards the rest of the mercenary group Band of Hawk due to his extremely Dark and Troubled Past. Most of the Band of Hawk hate him and barely accept him as Raid Leader, but after fighting numerous battles alongside them (ending a hundred year war in process) and even celebrating victory together, the Band come to adore him. When Guts leaves, things go From Bad to Worse as not only are the Band distraught but their leader Griffith can't cope with losing his man crush and sleeps with the princess of the kingdom, earning him a year of being tortured. Guts returns in timely fashion to save the Band from assassins in a Big Damn Heroes moment, earning the trust of the Band again and helping them free Griffith from captivity.
    • Things do not go well for the Band of Hawk in the end however, as Griffith pulls a brutal Face–Heel Turn and sacrifices all of them to a horde of demons, so he can have the power of the God Hand. The unjust deaths of most of his friends puts Guts on an Unstoppable Rage for two years where he straight-up kills every demon he sees, and plans to avenge his companions by killing Griffith as slowly and painfully as possible. However, Guts eventually attracts a new group of allies, a Ragtag Bunch of Misfits who develop into True Companions as they fight alongside each other.
  • In Ranma ˝, this is Ranma and Ryoga's friendship to the core. Ryoga may have spent half his life obsessed with exacting vengeance against Ranma, and Ranma may hate the whole P-chan situation, but by the end of the series they've had so many Enemy Mine team-ups that they're probably the most trustworthy ally either one has. After Mousse joins them to help defeat Prince Herb, he too falls under this category.
  • From Tengen Toppa Gurren Lagann: Yoko to Kamina and Simon. Later on, Viral becomes this towards Simon.
  • Haruhi Suzumiya: Sure, Mikuru Asahina, Itsuki Koizumi, and Yuki Nagato may have competing objectives and ideals, but when Kyon tells them that, for example, he needs Yuki and Mikuru to help him fix an alternate universe, they will move mountains to achieve the goals. This has reached the point where the three of them have sworn allegiance with the SOS Brigade, and are willing to go against their vastly more powerful superiors if they end up with a conflict. Kyon and Koizumi are particularly noteworthy given Kyon's initial dislike and distrust of him. By the ninth light novel, Kyon has come to trust Koizumi and begun to include him on the list of people he cares about whereas earlier novels he only lists Haruhi, Mikuru, and Yuki. Kyon and Koizumi are still definitely VitriolicBestBuds, but they know they have each other's backs. Koizumi and Asahina also stand out given that they were the two who were most philosophically opposed regarding Haruhi's power, and both separately tried to convince Kyon to distrust the other one. But Koizumi is the first person Asahina goes to in Endless Eight when she finds out she is stranded in time, Koizumi and his Organization work to rescue Asahina when she is kidnapped in the seventh light novel, and by the eleventh book Koizumi tells her older self that he considers present-day Asahina to be a loyal friend even though he doesn't trust the older one.
  • Pokémon Special give us Gold and Silver. They first meet after Silver steals one of Prof. Elm's Pokemon, and Gold sets out to beat Silver and retrieve said Pokemon. They meet up a few more times, and Silver tells Gold to stay out of his way each time. They don't start to act like friends until the Lake of Rage, when Gold finds out Silver's backstory, Silver sees Gold stand up for him, and they realize they have a common enemy in The Mask of Ice. At the end of the saga, Gold sacrifices himself to so that Silver (and Crys) won't have to, and Silver almost cries because of it. Gold gets better.
  • Pokémon gives us an odd example in Ash's Charizard. It started perfectly happy and loyal as a Charmander, but after evolving into Charmeleon, became defiant and disobedient. This trend continued for quite some time after it evolved into Charizard, though its disobedience was more a result of pride and overconfidence than simple spite. When Charizard came close to death when hit by a Poliwrath's ice beam, though, it watched as Ash worked hard to keep its tail flame lit, even though he was hurting himself in the process. Thereafter, it became steadfastly loyal.
    • This is the case for almost every Pokemon Ash has ever caught. He wouldn't even have the trust of his starter Pikachu if the two hadn't been attacked by Spearows. Combine that with how many Pokemon he befriends specifically because of a Team Rocket attack...
  • Persona 4: The Animation deconstructs this trope. The Protagonist Yu is forced to live out his nightmare in which the murders stop in his town. With no more murders, all of his friends drift apart, because the only thing keeping them together was solving the murders, and without them, they had nothing in common. In the end, it was just that, a nightmare induced by Mitsuo's Shadow. In reality, they had already developed into True Companions.
  • Higurashi Rei shows that, if the tragedies in everyone's life never happened, they wouldn't be friends. On top of that, Rika's closest friend Satoko would be bullying her and Keiichi wouldn't even be in Hinamizawa.
  • In Mai-HiME, Natsuki and Mai initially dislike each other, but by the end of the series, consider each other close friends.
  • In Fullmetal Alchemist, Ed and Ling start out with a rough (very rough) alliance based upon mutual goals. After finally escaping a pocket dimension, in which they had to fight a giant hellbeast, they immediately fistbump, and have a better understanding of each other in the continuing crises. Not that they ever stop bickering.
    • In a more general sense, almost everyone in the series got closer to their friends facing adversity together (and everyone fights less while fighting other stuff).
  • The members of the 104th Trainee Squad become this, in Attack on Titan. Those that weren't already this after three years of brutal training become it in the aftermath of the battle for Trost.
  • Akina and Hibari of Don't Become an Otaku, Shinozaki-san! dislike each other immediately upon meeting, however their experience winning a Tabletop RPG, and Akina's realization that Hibari is wrapped around Ayu's finger much like she is Kaede's, help them start to bond. In a later chapter, they bond further when Akina learns that, like herself, Hibari keeps her being an otaku secret and they have to work together to protect each others' secret from their non-otaku friends. They eventually develop into a pair of Vitriolic Best Buds.
  • Ushio and Tora: Ushio often whacks Tora with the Beast Spear to keep him in line, and Tora always makes the excuse that no bakemono but him is allowed to eat Ushio, but as the story progresses the two become fast friends and watch each other's back - even while still giving the same excuses as ever.
  • Usagi and Rei in the 90's Sailor Moon. Rei was outright mean to her at times and they always teased or mocked each other, then the whole love triangle between them and Mamoru/Tuxedo Mask started. By the end of the first season they become really close in senshi-related issues. When Rei dies in the second to final episode of the first arc, Sailor Moon goes Heroic B.S.O.D., after everyone's revived and they go through more adventures, Rei is almost always the first one to shout Usagi's name and stand up for her when she needs it, and Usagi returns the favor as much as she can.
  • In Endride, it is an understatement to say Emilio and Shun don't get along, but from jailbreaking to running off to join revolutionaries to fighting off the Truculent, they begin to rely on each other out of necessity, and keep coming to each other's rescue even when they can't explain it to themselves.
  • In Brave10, most of the Braves are weirdos who come to appreciate each other through tense combat situations rather than the usual avenues.

    Comic Books 
  • Angela and Gamora from Guardians of the Galaxy. When Angela was pulled from Heven due to the events in Age of Ultron, she charges toward the Earth from outer space, only to be intercepted by Gamora who attacked her. She was captured when the rest of Guardians arrived and managed to defeat her. After an interrogation, Angela claimed she was only heading to Earth because she wanted to see it by herself. The Guardians realized they actually incited the fight, freed Angela and accompanied her to explore Earth. While Angela's with the team, she eventually became close to Gamora and as teammates, they are qualified enough to be Smash Sisters.
  • Dunstan and Enna in The Autumnlands: Tooth & Claw are fast friends and they bond over the tragic fall of Keneil. To the point of Dunstan actually clutching Enna in mid-air.
  • In Thunderbolts, when they were sent after Spider-Man, MACH-1 was delighted with the prospect of bringing down his old enemy, even suggesting at one point they could kill him and claim it was an accident. After they fight as Back-to-Back Badasses against the rest of the Thunderbolts under mindcontrol, and Spider-Man saves his life, MACH-1 gives him the evidence he needs to clear his name, because he couldn't betray him after fighting next to him like that. (Also, realizing that he was Becoming the Mask.)
  • Dick Grayson (the first Robin) had this with Jason Todd (the second Robin). Dick resented Jason for taking his place, and Jason didn't like Dick for assuming he knew better than Jason did (which, after all, he did). After an evening together saving Alfred's life, they got close enough that Dick offered to be there when Bruce inevitably turned dickish again.
  • Hulk and his Warbound became friends after experiencing great challenges together as gladiators, and their first moments of cohesion are in the volcanic gladiator training camp, thus being almost literally fire forged. Newer members of the Warbound (such as Caiera and Kate) join the Warbound after similar trying circumstances. In-universe, the term "Warbound" explicitly invokes this trope, having fought side-by-side they have bonded and become bound together.
  • In an issue of X-Factor, Scott smashed up the house where he had lived with Madelyne, and found the baby's rattle. A cop finds him in the ruins and is belligerent, addressing him as "mister", threatening arrest. A Sentinel attacks, and they must join forces against it. After its defeat, Scott speaks of the arrest, and the cop says "son", he didn't remember it like that at all; the Sentinel had smashed up the house.
  • In an issue of X-Men, Wolverine was enraged by Rogue joining the team. After the rest of the team was taken out by poison, they go after the enemies responsible together. It culminates in Rogue taking an attack meant for Wolverine and Mariko — and Wolverine forcing her to absorb his healing factor to save her life despite his own injuries.
    • Although most other adaptations like to play up their conflicts, Cyclops and Wolverine actually develop a begrudging respect for one another in the comics. This was most pronounced after Jean died in the 2000s, when the two actually got a long extremely well until Schism, though their relationship was still a bit rocky.
    Cyclops: I've dated two psychics. My father is an emotionally distant space pirate. My time-traveling son from the future is older than me. My younger self hates me... and yet still... somehow... you were the most complicated relationship in my life.
    • Wolverine and Angel have also become this after stubbornly hating each others guts for several decades.
  • Punisher: War Journal: Frank and the Rhino make peace as they face Alyosha Kravinoff, the new Kraven, in his sadistic game of hunting supervillains with animal motifs. Over the course of the incident, it's revealed that the murder that set Frank on the Rhino's tail was an accident (and that Rhino sends money to the man's widow), and when Frank saves Rhino's life they decide to call it even. They then develop a Sam the Sheepdog/Ralph the Wolf sort of relationship, except they've cut out the "antagonize one another" part entirely.
  • Played with in Anti-Venom between Eddie Brock and Frank Castle: after taking down a drug lord together, Eddie Brock thinks they've got this when Frank Castle appears to let him live. Frank Castle, on the other hand, knows he just ran out of bullets.
  • Victor Von Piro and the Frank's gang in Mini Monsters. At first, Victor doesn't get along with them and the Frank's gang dislike him completely (Except Piruja who is obsessively in love with him). However, Frank only admitted him because he was so socially awkward that he would not make friends of his own. However, despite his strong dislike for them, he prefers being with them than his biological family (A very embarrasing one).
    • Piruja can also count, but she's liked a lot more than Victor, as she's accepted when she's not in her Abhorrent Admirer mode.
  • Zayne Carrick, Marn Hierogryph, and Jarael in the Knights of the Old Republic comic. Attempting to clear Zayne's name all while being on the run from five muderous Jedi Masters may have something to do with that.
  • In H'el on Earth, when Superboy meets Superman for the first time, he's untrusting of him; only teaming up with Superman because he saved his life. Over time, Superboy warms up to him, impressed by how well he handles situations. He even offers to call in his friends, the Teen Titans to help battle H'el.
  • When Xavin first showed up, he/she was not particularly well-liked by the Runaways, who suspected that he/she was just taking advantage of Karolina's low self-esteem, and who found his/her arrogance annoying. However, Xavin earned his/her place on the team after risking his/her life to distract the Gibborim while the rest of the team tried to talk Chase out making a deal with them to restore Gert to life.
    Molly Hayes: I don't care what shape you are... you're totally my sister now.
  • Whirl and Cyclonus in Transformers: More than Meets the Eye. At the start of the series the two despise each other to unbelievable degrees, to the point that they keep attempting to murder each other whenever they get the chance. However after they're forced to work together and actually talk during the season finale, they realize that they're actually Not So Different and develop a sort of respect/kinship for one another. This leads them to agree to drop their rivalry. By season 2, they've become so amicable that Whirl defends Cyclonus whenever someone insults him.
    • This happens quite a few times in the original Transformers comics but one of the most unusual examples is Springer and Carnivac. The leaders of the respective Autobot and Decepticon elite groups, when forced into an Enemy Mine situation against Galvatron and Megatron during "Time Wars" they save each other's lives (despite Carnivac being under orders to kill any Autobots left standing) and are firm friends from then on, repeatedly coming to each other's rescue until Carnivac effectively ends up defecting to the Autobots.
  • Red Sonja's The Art of Blood and Fire sees her collect six artisans for her patron. As they adventure alongside her they withstand Lizard Folk attack, a Beastly Bloodsports arena, an army of pimps... When Sonja is captured near the end of the arc they all contribute to her escape (except for the one who was recruited last, who is distracted by his own artistry).
  • While the deadpan and calculating Tim Drake, hot blooded egotistical totally radical Kon-El, impulsive ditzy genius Bart Allen, and socially awkward but morally outspoken ascended fangirl Cassie Sandsmark have some trouble meshing at first with their opposing personalities and interests often leading them to fight and mistrust each other it does't take long for them to become True Companions while fighting alongside each other as Young Justice.

    Fan Works 
  • Axis Powers Hetalia fanfic Gankona, Unnachgiebig, Unità: Believe it or not, the former Axis Trio was not always close. Like in canon, Germany was borderline abusive towards Italy while Japan was aloof. However, through Italy's refusal to be put down by them and continued kindness towards them, they warmed up to him. That, and having to work together through WWII and the Cold War also helped in cementing their bonds. Probably.
  • Cenotaph features the Skitter and the Undersiders. Not as close as in canon yet, but still on good terms, and friendly... And also Purity, who joined up while Taylor was fighting the ABB. Both helped each other, Taylor giving Purity hope that her attempts to clean up Brockton Bay would bear fruit, and Purity giving Skitter an ally in a time when she felt very alone.
  • Remaining consistent with the original series, A:TLAR's Team Avatar never leaves a member behind, (except for that one time...) and every one of them will fight and die alongside the others, proud to have known such great warriors. However, they can be considered closer to Fire-Forged Friends than the original, due to the general hostilities between members. As time goes by, they will surpass numerous conflicts, including Katara and Aang's feud, Sokka and Suki's brief falling out, and Zuko and Iroh's temporary split from the team during Books Two and Three.
  • Blind: While already on good terms, 3 years as missing-nin turns Naruto and Gaara as this.
  • The members of Hakumei fall under this.
  • In Origins, a Mass Effect/Star Wars/Borderlands/Halo Massive Multiplayer Crossover, Aria's assault squads end up fighting alongside geth who by their own words had never interacted with organics before.
  • This happens with Vale and Obsidian in the Hunger Games fanfic Some Semblance of Meaning. Initially, she distrusts him completely and hates him even past the point of rationality, while he views her as a nice person, but a rival nevertheless. However, after the two meet again in the arena while fighting a mutt that killed people that they both cared about, they become allies and friends... and even more than that.
  • Fate Zero Sanity: This happens between Saber and Berserker. While they were certainly on friendlier terms than most of the other Servants at the beginning of the fic, they were still enemies. Fast-forward three battles, with an official alliance and several emotional moments thrown in there, and they have the most positive relationship of all the Servants, proudly considering the other friend. So much so that Saber actually forgives the later (in her thoughts) when she stabs her in the chest to try and stop her from destroying the Grail, spending her last moments reflecting on their time together and thanking the Servant for that.
  • Mortality: Holmes and Watson, are, like counterparts are genuinely close to each other, but the events make them even more closer than they already were. D'aww.
  • Sailor Moon: Legends of Lightstorm: Sailors Jupiter and Mars appear to have become this, going so far that they begin laughing after beating each other senseless during an unsupervised training match.
  • The Diva Army from the WWE fic, The Return-Remixed. At the beginning of the story, many of them were enemies, but united purely by their desire to vanquish DEAR. By the end of the story, just before the climactic battle royal, Natalya points out how she didn't particularly care for some of them a few months earlier, but now considers them friends and the ones she wants fighting by her side.
  • Their Journey: All of the protagonists become this over the course of the story, most notably expressing itself at the end of Chapter 8.
  • This Bites!: Cross and Tashigi end up as this, or at least Fire-Forged Friendly Enemies. Anyway, the aftermath of the encounter with Mr. 3 results in Tashigi developing respect for Cross.
  • Corrin Reacts: Flora and Corrin's relationship begins like this. Back when they were younger, Flora, out of hatred for Garon and wanting to return home after being kidnapped, attempted to flee the Northern Fortress and nearly dies after falling into a canyon. Corrin saving her life and nearly dying himself in the attempt due to a blizzard instantly earns him her respect and both become fast friends after they recover.
  • Zootopia 2 The Movie: Because of his strong dislike of cops, Bart doesn't necessarily get along with Judy and Nick at first, especially not Bogo, and makes two attempts to escape from them while the mammals view Bart as trouble making nuisance with the potential to cause a panic and want nothing more then to be rid of him. But after having some fun at a hotel they are hiding out in and saving Judy's life Bart starts to become friends with Judy and Nick and vice versa. He also gains a grudging respect for Bogo after he comes to their aid during the Final Battle.
  • A few sidestories of Pokémon Reset Bloodlines have this dynamic:
    • In the Gardenia Interlude, the title character ventures into the Eterna Forest to find Cheryl, who has gone missing for a week. A challenger named Sho shows up as soon as she exits her Gym, and ends up following her to the forest and eventually to the Old Chateau to find Cheryl.
    • In the Laramie Gaiden, Leeroy Laramie, a Trainer, and Jenkins Jackrum, a Ranger, have to set aside their differences to survive when they end up stranded on a Deserted Island (their respective nations are at war with each other over conflicting philosophies about Pokémon).
    • The Agatha & Sam Gaiden shows an adventure of Elite Four Agatha and Professor Samuel Oak when they were young trainers and rivals. They are forced to venture into the depths of Drowning Woods when Agatha's younger brother goes missing.

  • Toy Story: Woody and Buzz Lightyear forged this out of their initial rivalry and their ordeal in Sid's house.
  • In Tangled, the Bar Brawl and escaping down the tunnel together gets Flynn friendly enough to ask why she didn't go before; The Chase, culminating in their nearly drowning, and their final escape, cements it so that Flynn no longer sulks over guiding her, and they confide in each other.
  • Monsters University, Mike and Sully finally become true friends after their competitive rivalry when the two have to escape a human summer camp by teaming up to scare a group of adults to power the door from their side.
  • In Ice Age, Manny, Diego and Sid become this during the events of the first movie.
  • Zootopia: Judy and Nick. At first they are stuck working together on a case because he's her only lead and she blackmailed him into helping her with the threat of a tax evasion arrest, but as the case progresses they have many harrowing experiences, including Judy saving Nick's life twice, and they become best friends.
  • In The Emperor's New Groove, Kuzco and Pacha initially don't like each other because of Kuzco's It's All About Me attitude. During their adventure, they are forced to work together to get home, saving each other's necks along the way, and by the end of the movie, they seem to somewhat be friends.

    Films — Live-Action 
  • The Mad Max franchise loves the trope. Justified in that in a post-apocalyptic society, trust is hard to come by.
    • Mad Max 2: The Road Warrior has Max and Papagallo. The Gyrocaptain tries to invoke this between himself and Max but fails although between himself and the great north tribe it seems to work just fine, since the epilogue states that he became their leader for a time.

  • In Alfred Hitchcock's The Lady Vanishes, Iris Henderson (Margaret Lockwood) and Gilbert Redman (Michael Redgrave) start off on the wrong foot when Iris has Gilbert thrown out of his hotel room for his noisy music-making and Gilbert blackmails Iris into reinstating him. However, when a fellow passenger on the train in which they are travelling mysteriously vanishes, the two join forces to try and find out where she's gone and why so many people are lying about her disappearance. There is a Relationship Upgrade at the very end of the film.
  • A really great example of this in My Fellow Americans.
  • At the beginning of Korean table-tennis movie As One, the North Korean and South Korean ping-pong teams have been thrown together as one because their governments think it's a neat idea.

  • Dan and Occam in The Patriot: Dan constantly talks smack about former slave Occam, right up until the latter runs back to rescue the former in the heat of battle. From then on, Dan is honored to have Occam at his side.
  • In the Dawn of the Dead (2004) remake, the security guards at the mall are initially hostile towards the new arrivals, but eventually their common purpose against the zombies makes them allies. Not all of the survivors manage to work together, though, and indeed this trope is rare in the zombie movies made by or remade from George A. Romero. Usually the conflicts between survivors escalate to become their undoing.
  • Lord of the Rings:
    • Gandalf and Pippin come to mind. While the Fellowship were True Companions, Gandalf never seemed to like Pippin very much. Once they had fought together in Minas Tirith, lived through the siege and saved Faramir's life, Pippin seemed to have become Gandalf's favorite among the Fellowship members (especially in the movie).
    • Also, Gimli and Legolas:
      Gimli: I never thought I'd die fighting side-by-side with an Elf!
      Legolas: What about side-by-side with a friend?
      Gimli: Aye... I could do that.
    • Continuing the trend; in The Hobbit: An Unexpected Journey, Thorin regarded Bilbo as The Load for most of the film. In the final battle, Bilbo fought off Azog's Mook before he could kill Thorin. After the company was rescued by the eagles, Thorin embraced Bilbo as a brother and friend.
  • In the newest Star Trek movie, Kirk and Spock.
  • Stargate: Jack O'Neil and Daniel Jackson in the original movie.

Perseus eventually comes to say he trusts the surviving men, woman Io, and whatever the hell the Djinn is.
  • Lethal Weapon: Riggs and Murtaugh don't particularly like each other when they first meet. But by the end of the film, Murtaugh is inviting Riggs to spend Christmas dinner with his family. And after a while, Riggs is family.
  • Flight of the Intruder: The hero and his CO

  • Sucker Punch has a girl named Baby Doll gets together this team of women after befriending Rocket. Initially a few of the women are questioning over her plans...

  • A famous example of this trope happens in A New Hope. When Luke Skywalker and Han Solo first meet they don't like each other at all, it is only after saving Leia together that their friendship begins.
  • The Avengers (2012):
    • When the Avengers first assemble, they don't get along at all. The main arc of the film is this motley collection of alpha dogs going from "we're six guys who all happen to want the same thing" to becoming the motherflippin' Avengers.
    • Special mention has to go to both Captain America and Iron Man. At first, the two really can't stand one another, with Cap even wanting to punch Tony's lights out at one point, but with the fate of the world at stake, they're more than happy to drop all grudges and get their act together to save humanity from Loki and the Chitauri.
  • Nonhuman examples: Godzilla, Rodan, Anguirus, and Mothra. A strange group, to be sure. But each of these four became fire forged friends in different films in the Showa Era. Actually, Godzilla, Rodan, and Mothra are pretty much Toho's Power Trio. Anguirus is something like Godzilla's sidekick. Godzilla and Anguirus are adversaries during the second Godzilla film, but somehow or other ended up as great friends from that point after. How Anguirus manages to forgive Godzilla for— in essence—killing him is unknown, but even the Trendmaster's toy line roster calls Anguirus one of Godzilla's staunchest allies, and most films in which they appear together as allies make it clear that if Rodan is Godzilla's Right Hand, Anguirus is the Left. Rodan and Mothra become fire forged friends with Godzilla when they team up to defeat King Ghidorah, and remain friends, or at least Friendly Rivals from that film forward.
  • Ah Jong and Inspector Li from The Killer, who went from being somewhat amicable adversaries to something akin to Blood Brothers when the two joined forces at the beach house to defend themselves and Jenny against the assassins after Ah Jong.
  • The Karate Kid: John Kreese and Terry Silver.
  • Jack the Giant Slayer: At their first meeting, Elmont is not impressed by this bumpkin Jack. After Jack rescues him and Isabelle from being cooked by a giant and they subsequently send another giant plummeting to his death, Elmont gives Jack a King's Guard badge, saying, "You've earned it."
  • Guardians of the Galaxy has an Earth-born outlaw, the adopted daughter of a galactic overlord, a Literal-Minded Blood Knight on a Roaring Rampage of Revenge, a genetically-modified cybernetically-enhanced raccoon, and a Cloud Cuckoolander tree monster banding together, initially for a big pay-off, then later to stop the destruction of a civilized planet. Before heading off to the final battle, they all even concede that they would be happy to die by their comrades' sides. We are Groot, indeed.
  • Stu Miley starts out hating the titular character of Monkey Bone. Then they sneak into the Land of the Dead together to steal an Exit Pass, learn to rely on one other, and Stu even admits that he's come to like him. Then it gets averted all to hell when Monkey Bone betrays him, steals his exit pass, and leaves Stu in limbo.
  • At the end of Terminator 2: Judgment Day, while Sarah isn't moved to tears by what the T-800 intends to do like John is, she still shakes his hand in respect. It's quite a thing too, considering her previous encounter with one of those things.
  • King George starts with a mild dislike for Churchill and his methods in Into the Storm (2009), but as the war rages on, they grow closer. A similar series of events happens with Roosevelt and Churchill.

  • In the climax of Jurassic World Rexie, the same T-rex from Jurassic Park and Blue join forces to bring down the film's Big Bad the Idonimus Rex. Despite Rexie having a history of battling and killing raptors, even bearing scars to prove it, she and Blue appear to have a mutual respect after the battle, and go their separate ways peacefully.
  • Katniss Everdeen with Johanna Mason in The Hunger Games: Mockingjay Part 1 and The Hunger Games: Mockingjay Part 2.
  • The biggest example in The Hateful 8 is the unlikely friendship between Warren and Mannix. Mannix idolizes a racist Confederate General, and Warren, who is black, kills that General after goading him into reaching for his gun. A little later in the film, the two are the only remaining people in the lodge who aren't part of the Domergue gang. Warren trusts Mannix with a gun on the basis that he was very close to drinking poisoned coffee, and Mannix returns the favour by sticking to his principles instead of conspiring with Daisy to kill Warren. Even after dealing with the gang, the two bond as they bleed out.
  • We're the Millers: Or better yet Fire-Forged Family. The Miller family (except Kenny, who just happens to be a Nice Guy) initially despised each other when they were paired together for the drug delivery, but they grew to care and love each other the course of the film.
  • The Force Awakens: Finn bonds with both Poe and Rey like this, in similar situations. Finn acts as the Guy in Back to both Ace Pilots shortly after meeting them and the post-combat high cements the friendship.

  • Invoked in Nineteen Days. When a senior KGB official makes a back channel piece offer allegedly from Khrushchev, the Americans have to decide if it's genuine. They decide it is on finding evidence that the two served together during WW2.
  • In Wild Wild West, when Jim West and Artemis Gordon are first assigned to work together, they keep arguing with and undermining each other. By the end of the film, they've learned how to work together to save President Grant.
  • Josh and Dylan in Geek Charming. They even become a couple at the end of the film.
  • Dragonheart: Bowen and Draco start off as enemies, but after their fight ends in a stalemate and as they con villagers together, they become best friends willing to put their lives on the line for each other.
  • I Shot Jesse James: Robert Ford and Jesse James become these, having fought their way through numerous bank robberies with zeal.
  • Beauty and the Beast (2017): LeFou becomes this with Mrs. Potts in the climax after his Heel–Face Turn. When he saves her life, they work together to defeat the villagers, befriending each other in the process.
    LeFou: I used to be on Gaston's side, but we are so in a bad place right now.
    Mrs. Potts: (kindly) You're too good for him anyway.
    LeFou: Yeah.
    Mrs. Potts: (smiles) Should we get back to it then?
    (LeFou nods enthusiastically and runs off with her to join the servants in driving off the villagers.)
  • Only the Brave: Literally. The Granite Mountain crew go from a team to being brothers through facing deadly wildfires head on.

  • How the Animorphs became friends. Before the meeting with Elfangor, they weren't close - Marco and Jake were best friends, Cassie and Rachel were best friends, but Rachel and Jake weren't close cousins, Cassie and Jake only barely knew each other, and Rachel and Marco only knew of each other. Nobody knew or liked Tobias much, and, of course, they had never met Ax. But as Marco notes, after someone saves your life a couple times, you tend to cut them a little slack.
  • Roland Deschain's second ka-tet in The Dark Tower, very much so. Eddie comes close to murdering Roland in cold blood while in the throes of heroin withdrawal and Susannah, while controlled by her Detta Walker persona, tries to kill both of them in cold blood several times.
  • From the Deryni works by Katherine Kurtz:
    • Mátyás Furstán becomes such a friend with Kelson, Morgan and Dhugal as a result of their success in foiling Mahael's coup d'etat and Teymuraz's attempt to murder Mátyás in King Kelson's Bride. The process may have begun years earlier when Nigel Haldane protected himself and Mátyás' nephew Liam from assassins in The King's Justice.
    • Also in King Kelson's Bride, the existing alliance between the Hort of Orsal and Gwynedd is strengthened, and the formerly tense relations between Tralia (the Orsal's principality) and Torenth moves in this direction. This is in reaction to both an assassination attempt against Kelson and Liam at the Orsal's summer palace of Horthánthy and the need to pool resources against the threat of an escaped Teymuraz. Létald says, "It seems we must all trust one another far more than we had planned or dreamed."
  • The Gone series:
    • "Brittney had no romantic feelings for Edilio, but what she had went a lot deeper. She would rather burn for eternity in the hottest fires of hell than let Edilio down. "
    • Dekka and Sam:
    Sam: "I don't want to sound weird, but you know I love you, right?"
    Dekka: " Love you too, Sam."
    • Diana has become this with Astrid and Sam at the end of Light.
  • Harry Potter: Harry and Ron's friendship with Hermione stems from a fight with a troll.

    • The battle in the Department of Mysteries in Order of the Phoenix pulls Luna, Neville and Ginny into the group, as well.
  • In Darkness Visible Lewis and Marsh don't become friends until after the disaster at Wandsworth Prison, the first time they save each other's lives (but not the last).
  • Temeraire: John Granby is initially extremely hostile to Laurence out of friendship to another officer who lost his chance at promotion because Temeraire wanted Laurence for a captain instead. But after being faced with Laurence's heroism and concern for his dragon in Temeraire's first combat action, Granby realizes he was being a Jerk Ass, apologises to Laurence, and becomes his friend.
  • Part of the main plot of Honored Enemy, of The Riftwar Cycle by Raymond E. Feist. During the war between Midkemia and the empire of Tsuranuanni, Dennis Hartraft and his company of Midkemian soldiers find themselves pitted against Asayaga, commander of a Tsurani platoon. The plot hook? Both companies find themselves in the territory of the vicious moredhel (dark elves), who are at war with both nations. These circumstances force the Midkemians and the Tsurani to work together to survive. Eventually, despite many fallings-out due to cultural differences and Dennis' pre-existing hatred of Tsurani for personal reasons, the two become loyal friends.
  • Common in Warhammer 40,000 literature:
    • In Dan Abnett's Gaunt's Ghosts novels, while Rawne's hostility to Gaunt lasted through many battles, their work together in the Gereon resistance makes friends of them. (In His Last Command, Gaunt reflects on the strangeness of this.)
    • In Dan Abnett's Brothers of the Snake Antoni and Princeps become rather close after saving each others lives while accompanying Priad on a Dark Eldar hunt.
    • In Blood Pact, Kolea and Baskevyl talk, random chit-chat, in the lock-down when they can't act; they know it means nothing, it just expresses their friendship.
    • In William King's Space Wolf, after desiring Revenge the entire novel, Ragnar sees Strybjorn save his life, and then go down before a Chaos-tainted force. He realizes that he does not, and should not, desire revenge, which is petty in face of their common foes. When Strybjorn lives, Ragaor sends the others, over their objections, to Bring News Back, so that he can treat Strybjorn's injuries and bring him out.
    • In Graham McNeill's Storm of Iron, Captain Eshara speaks of how war brings out the best and the worst in men, and explains that the bond of brotherhood among the soldiers is not to be found in any other way.
    • In Graham McNeill's Ultramarines novel Dead Sky Black Sun, when Leonid saves the Lord of the Unfleshed from being attacked In the Back, the Lord salutes him as "Now you Tribe!" Minutes later, when the Lord saves his life, Leonid thanks him, and the Lord says, "You Tribe."
    • In Graham McNeill's Horus Heresy novel False Gods, the reunion of Torgaddon and Tarvitz makes their friendship from the heat of battle clear to everyone.
    • In Graham McNeill's Horus Heresy novel Fulgrim, the parting of the Iron Hands and the Emperor's Children is sad because their fighting side-by-side had made new friendship and renewed old ones. Fulgrim, the Primarch of the Emperor's Children, and Ferrus Manus, Primarch of the Iron Hands, were good friends (and brothers). They met under Mount Narodnya, where they forged weapons for three months without pause. Fulgrim forged the hammer Forgebreaker, that could level a mountain with a single blow, and Ferrus Manus had forged the sword Fireblade, that forever burned with the fire of the forge.
    • In Ben Counter's Horus Heresy novel Galaxy In Flames, when Tarvitz is trying to warn the betrayed Marines on Isstavan III, he invokes The Power of Friendship to get Garro to believe his word. It is their Fire Forged Friendship that wins him.
      As my honor brother I ask you to trust me like you have never trusted me before. On my life I swear that I do not lie to you, Nathaniel.
      • Later in the same book, Tarvitz tries to join the Emperor's Children partly so he will die with his brothers in defiance of the treachery that separated them from other battle brothers. In the end, he realizes that he knows the names of all the men who are dying with him, even those who were not in his legion. In the face of certain death, he consoles them with the thought that they hurt Horus.
      • In Matt Farrer's "After Desh'ea" (in Tales of the Heresy), Angron laments his dead comrades from the Gladiator Revolt; his War Hounds/World Eaters crave it from him so desperately that Kharn feels envy listening to his account.
    • In Sandy Mitchell's first Ciaphas Cain (HERO OF THE IMPERIUM) novel For the Emperor, the Valhallan 296th/301st is an amalgamation of two regiments that were both depleted by a Tyranid attack... and each regiment collectively hates the other one. One of the first things the titular commissar has to do when he's reassigned there is put down a riot between the two factions through sheer force of will. Afterward, however, thanks to both reforms on Cain's part (including a regimental redesignation to the 597th) and success in its first campaign, the regiment pulls together to become a top-notch fighting force.
      • Amberley also says that Cain has an unusually tight bond with the officers of the regiment, and they come as a comfort to his court marshal at the end of The Traitor's Hand.
    • In James Swallow's Horus Heresy novel The Flight of the Eisenstein, while waiting on a crippled ship to see who the Imperial forces that found them were, Garro, a Space Marine, feels a kinship with the common soldiers also waiting that he had never felt before. When the ship's captain checks what he is saying, Garro urges him to speak: their experiences together should permit candor.
    • In James Swallow's Blood Angels novel Deus Sanguinius, Solus laments having fired on his battle-brothers. (Indeed, in this novel, Rafen must make it clear whenever he refers to Arkio as his brother that he is speaking of a blood relationship on top of their being Blood Angels; everyone's first thought is of this trope.)
      • In Red Fury, after disputes between the Blood Angels and the Flesh Tearers — including a duel between Rafen and Noxx — they are sent on a mission. When frantically trying to escape they are last to get on the shuttle, and Noxx gives Rafen a hand up; in the take-off, Turcio sees Rafen help Noxx keep on his feet. Turcio notes what a change it is — and keeps it to himself. At the end, Noxx admits that he dislikes Rafen a little less.
      • Also in Red Fury, the Flesh Tearer Chapter Master Seth fiercely opposed the request of the Blood Angels Chapter Master Dante and proposed dissolving the Blood Angels, but while they are fighting the Bloodfiends, Seth is knocked so that he is falling in a pit. Shouting "Brother!", rather than "Cousin," Dante grabs him and drags him back. Seth asks if he's worthy of such an address, and Dante asks if he is. At the end, Dante asks the other chapters, again, if they will give him members of their Chapters for the Blood Angels, and Seth declares that they will. He cites the page quote and says that these events have come to pass so that they are reminded that they are not cousins but brothers.
    • In Dan Abnett's Titanicus, when Mechanicus units plug off to fight Chaos despite a schism, one conspirator who engineered the split complains that this trope means they will continue to follow the man leading them into battle.
    • In Lee Lightner's Warhammer 40,000 Space Wolf novel Sons of Fenris, Jeremiah and Ragnar have won each other's respect by the end.
    • In Ben Counter's Soul Drinkers novel Chapter War, Gresk and Pallas are veterans; they join Eumenes's revolt but find it hard to fight battle brothers. Gresk talks to Sarpedon in battle, telling him there is no need to fight, and letting him guess about the orbital attack, and is executed. When Pallas goes to fight Lygris, Lygris thinks he as much wants to be kill as to kill.
    • In C. S. Goto's Blood Ravens trilogy, Rhamah has his doubts about Ahriman, but wavers because they had, after all, fought side by side against the Harlequins.
    • In Andy Hoare's White Scars novel Hunt for Voldorius, we are assured in the epilogue that the events of the novel formed this between the White Scars and the Raven Guard. Although the last actual scene shows that the Raven Guard vanished, leaving the White Scars with plenty of questions, taking the woman who had been prisoner, and the White Scars were rather annoyed.
    • In Nick Kyme's Space Marine Battles novel Fall of Damnos, this happens gradually between the Ultramarines and Damnosian PDF as the Necron threat slowly turns them from defending and defended into friends, and sometimes even battle-brothers.
  • In Jim Butcher's The Dresden Files, the relationship between Harry and Marcone constantly teeters on the brink of this. Harry has to constantly remind himself that Marcone is the leader of the mob (though a nicer mob boss you couldn't hope to find) and his constant, unwavering assistance in battle is a matter of practicality, not any kind of amicable feeling.
    • In Dead Beat, this happens to Harry and Ramirez, as witness Ramirez's saying:
      "Everyone else who lets me ride on their dinosaur calls me Carlos".
    • One of the short stories is about how Harry met Murphy. He had been hired to track down a runaway child, who had wandered onto a bridge which happened to have a troll living under it. Murphy was nearby to help take it down. In Cold Days, Harry says they've been friends since that moment.
  • In The Fellowship of the Ring, Legolas and Gimli get along rather better after spending time together in Lothlórien after the Battle of Moria.
  • A few adventures together helped Mara Jade get over her hatred of Luke Skywalker. Especially in The Last Command when she killed his clone, freeing her from the Emperor's dying compulsion.
  • John Carter of Mars: In Edgar Rice Burroughs's A Princess Of Mars, John Carter and Kantos Kan forge this during their trials at the Gladiator Games and rescuing Dejah Thoris. In The Gods of Mars, John Carter observes:
    My old friend had won to the highest place in the navy of Helium, but he was still to me the same brave comrade who had shared with me the privations of a Warhoon dungeon, the terrible atrocities of the Great Games, and later the dangers of our search for Dejah Thoris within the hostile city of Zodanga.
  • In Andre Norton's Witch World, Koris and Simon Tregarth, starting with their first meeting. Later the men admit that despite the Falconers' hostility to women and so to the witches, the men of Estcarp have a relationship of less than total hostility, because they're all fighters together.
  • In Wen Spencer's Endless Blue, Turk, knowing that nothing unites better than a common enemy, intends to keep the new Reds away from his veterans until they have a common enemy to unite them. (It goes awry, but that's his intention.)
  • A Song of Ice and Fire: A lot of the Night Watch end up becoming this, but there are quite a few deconstructions of This Trope as well. Brienne and Jaime might count, although it's not so much forged in battle as being captured and tortured by the Bloody Mummers and it ends up becoming more of a Rescue Romance later on.
  • Maxie, Rosie, and Earl—Partners in Grime. Three kids who don't initially know each other, and are not inclined to get along (especially since one of them is a huge tattletale), end up ditching school together. They argue and get annoyed at each other, but come out of it as friends in the end.
  • Good Omens. Crowley, a demon, and Aziraphale, an angel, are quite obviously going to be enemies. However, after an indeterminate amount of time being Enemies, they came to realize that they had more in common with each other than their actual superiors. Thus, they came to an Agreement. They went from thwarting each other's actions to just going about their own business, with little acts of evil and little acts of good here and there, and occasionally holding down the fort for each other, as well as going out for lunch and drinks now and then over the past few millennia. Their part of the plot of the book is siding with each other again Heaven and Hell with the intent of averting the apocalypse. They also get the bonus points for Back-to-Back Badasses and It Has Been an Honor.
  • Suzanne Collins' The Hunger Games:
    • Katniss is terrified of this because she knows that in the end, she'll have to kill the other to stay alive. She still teams up with Rue, however.
    • To say nothing of the lead boy, who she purposely avoids for most of the games, hoping one of the other characters will do the dirty work for her.
    • Many of the victors in Catching Fire. Which makes the "game" much worse, as the victors have to fight against each other. Then again, many of them are more than ready to kill the others.
    • In Mockingjay there's Katniss and Johanna Mason.
    • It's implied that this also goes for Johanna, Peeta and perhaps Annie Cresta after the three of them were held captive and tortured in the Capitol.
      Johanna: We're old friends. We're very familiar with each other's screams.
  • In Flood, the main characters spent four years together as terrorist hostages. After they get out of their captivity, they maintain lifelong connections due to their shared hell.
  • The Three Musketeers:
    • On d'Artagnan's first day in Paris, he is challenged to duels by Athos, Porthos, and Aramis. Just as the first duel is about to start the group is challenged by four of the Cardinal's guards. D'Artagnan chooses to fight with the Musketeers, and the quarrels are forgotten when he is instrumental to their victory.
    • D'Artagnan and Rochefort spend the first book as nemeses. In an epilogue, it's explained that they fight several duels before ultimately becoming close friends.
  • In Rick Riordan's The Lost Hero, Leo assures Piper that even if Jason regains his memory, their adventures together will assure that they are still friends.
    • All of the Seven grow into this over the course of the series, by the end of The House of Hades even those of them who were the most unwilling in the beginning are True Companions.
  • In Lois McMaster Bujold's Cryoburn, Miles explains their connection to Raven as this, through his and Roic's being kidnapped and escaping together — covering up their older connection.
  • Conan the Barbarian: In "The Scarlet Citadel" Conan muses at the end that while Pelias unquestionably saved his life, his freedom, and his kingdom (both keeping him on the throne and preventing it from falling under an oppressor), he nevertheless never wants to lay eyes on him again. (Then, Pelias is unquestionably a Necromancer.)
    • In "The Shadow Kingdom", Kull feels this toward Brule. (No doubt aided by Brule's being the only one he can know is a real man.)
  • In Dennis McKiernan's novel Dragondoom the two main characters, a female human and a male dwarf, become this. Humans and dwarves hate each other at this point in time and they immediately take a dislike to each other. However, it turns out they are both after the same thing and quickly have to team up to survive attacks from the baddies trying to stop them. Eventually they develop romantic feelings for each other, but never get a chance to say so. Biggest Tear Jerker ending.
  • In Lewis Carroll's nonsense epic The Hunting of the Snark, the Beaver (a valuable crew member, although no one is quite certain why) and the Butcher (who specializes in killing beavers) bond over an arithmetic lesson and their mutual fear of the Jubjub bird.
  • A variant occurs in Fablehaven—the two protagonists, Kendra and Seth, are actually a pair of bickering siblings who never truly seem to get along. However, the trials they endure in Fablehaven bring them closer together, and help them to truly understand one another and become a true Brother-Sister Team. (It helps that Character Development occurs on both sides.)
  • Similarly, The Beyonders by the same author has Jason and Rachel. Although they do connect due to both being "Beyonders" from Earth, Jason is stubbon and Rachel is argumentative, which ends up pretty much like you'd expect. However, they do begin to connect, and Jason gains a great deal of respect for Rachel once she proves just how badly she wants to avert being a Neutral Female.
  • In Jasper Fforde's The Eyre Affair, Joffy muses how at first the war was pleasant, and the camaderie found nowhere else was a big part of it.
  • Elfsong by Elaine Cunningham had Danilo Thann and Elaith "The Serpent" Craulnober fighting together. While they did sort of lend each other weapons, the first time Danilo gave no-nonsense Elaith a sword loudly singing "Elminster's Jest" and the second time he grabbed the elf's inactive Moonblade (the reason of most pain in his life). Elaith had a foul temper in better situations, and both times was close to killing him after the action. So they eventually became Vitriolic Best Buds.
  • In John Hemry's Fearless, after Geary's ship and two others stay to control a hyperspace jump about to be destroyed, there are rumors that Geary had destroyed it, and the captain of the Diamond, one of the other ships, explodes with rage on hearing — he admits to not having thought well of Geary before, but that's a lie, and he would be proud to fight by Geary.
  • Bail Organa and Obi-Wan Kenobi in Star Wars: The Clone Wars: Wild Space. They eventually become close friends after driving each other crazy for weeks while cooped up on a starship, surviving the crash of said spaceship at the hands of the Sith, trekking through hostile wilderness, coping with Obi-Wan's reliving of his most horrific memories and keeping each other going despite considerable injuries. The two men end up trusting each other implicitly, despite their considerable differences.
    • Gavin Darklighter and Asyr Sei'lar. The first meeting between the two nearly results in Gavin getting executed for (perceived) bigotry despite the arguments of former attorney Nawara Ven, but a raid by Imperial stormtroopers intervenes. Gavin instinctively pulls Asyr out of the way just as the raid begins, allowing Asyr to realize she was wrong about Gavin being a bigot. They stick together until they escape the raid, and maintain a strong relationship afterward.
  • In the Dale Brown novel Shadows of Steel, this happens between Tony Jamieson and Patrick McLanahan. The former is most displeased by having to fly with who he sees as a disgraced now-civilian, while the latter is aloof and mission-focused. They eventually bond during their mission.
  • In War Maid's Choice the Sothoii who fought beside the hradani infantry against three devils and a horde of ghouls don't take kindly to insults against their former enemies, and those who fought beside Leanna and the other war-maids in an apparently hopeless defense of the king, including the king no longer find disparaging remarks about them all that funny either.
  • In Michael Flynn's The January Dancer, at one point Hugh remembers this forming during the civil war.
  • In the Artemis Fowl series, Artemis and Holly's relationship goes from kidnapper and victim (1st book) to reluctant allies (2nd and 3rd books) to friendship (4th book onwards).
  • In Robin McKinley's Sunshine, Sunshine and Constantine.
  • In Sarah A. Hoyt's Draw One in the Dark, after Tom's rescue, he, Rafiel, and Keith have a strange camaraderie that he reflects on.
  • In Andre Norton's Storm Over Warlock, Thorvald's manner toward Shann during the course of the novel is often brusque, despite a couple of After Action Patchups, but he is obviously friendly at the end when he explains Shann's Field Promotion.
    • In Forerunner Foray, when Ziantha escaped the mental Time Travel but Turan did not, she mourns and reflects on how for the first time, she had known an equal, and thought it was like the bond between crewmen or Patrol who had faced a common danger.
  • In Bernard Cornwell's Sharpe's Triumph, Sharpe reflects on how he and McCandless are as close to friendship as is possible between a sergeant and a colonel — not because of a battle, but because they had been prisoners together.
  • Brotherband has the Heron brotherband, a Ragtag Bunch of Misfits who band together in the goal of succeeding at brotherband training.
  • Rose Hathaway and Mia Rinaldi from Vampire Academy, were enemies until their captivity in Spokane in Frostbite. After saving each other's lives they became good friends.
  • The Stranger Beside Me: Ann speculates that she and Ted became friends because they worked together at the crisis hotline so often.
  • Averted in Steel Dragons of a Luminous Sky by Brian Trent. The protagonist gets shot In the Back by a compatriot during World War II. When he mentions this trope she just sneers, "We've known each other a goddam week. You set a low bar for friendship."
  • The Silerian Trilogy: Tansen and Josarian. Also blood brothers.
  • In Transitions the dwarves Arthogate and Thibbledorf Pwent bond over killing undead minions. Pwent was initially hostile to Arthogate, not knowing what to make of him, but fighting their way through hordes of undead on the way to Spirit Soaring does wonders for a blooming friendship between the two.
  • The kids in Mindwarp very much count, after being hunted by aliens. In fact, the end of the series has them all promising to remain friends, whether or not they have powers and whatever else may have changed.
  • Warrior Cats: In The New Prophecy, most of the characters didn't know each other very well and in some cases were openly hostile to each other before their journey - Squirrelpaw and Brambleclaw didn't get along, and Crowpaw was aggressive to everyone (but particularly Brambleclaw due to a border conflict) - but in the end they become true friends due to everything they'd faced together.
  • The Machineries of Empire: Jedao and Cheris slowly come to like each other, even if he's still scheming and she's still unsure whether she should trust him.
  • Wander has Wander and Dagger. When they first meet, Wander saves him from the smilers against her better instincts, and they grow closer and closer over the course of the book until she's willing to risk her life to save him, and vice versa. By the end of the book they've grown into full-fledged Platonic Life-Partners territory, Wander, who's only known by her nickname and insists that Dagger is, too, willingly trades names with him, showing that she trusts him absolutely.
  • In Wolfheart, King Varian Wrynn of Stormwind and Lord Genn Greymane of Gilneas are at odds, although it's mostly Varian disliking Gilneans for abandoning the Alliance during the Third War. Eventually, the two go on a hunt together and end up fighting a bear. The mutual struggle results in them bonding, and Varian ends up leading the Worgen reinforcements in a counterattack against the Horde.

  • Game of Thrones:
    • Jaime and Brienne after their ordeal in the Riverlands, when they are both captured by enemies and find that they are each other's only allies.
    • Jon, Pyp, and Grenn had a very rough start, but they eventually become True Companions along with Sam.
    • Arya with Hot Pie and Gendry, as their experiences being hunted by Lannisters, imprisoned at Harrenhal and travelling through the wartorn countryside together quickly bond them.
    • Deconstructed with Arya and Sandor Clegane in Season 4, as she fights alongside him and even binds up his wounds indicating they're heading toward this trope. However, Arya claims his name is still on her death list and she's is still technically his prisoner so, despite a temporary alliance, their relationship remains uneasy and lacks the genuine trust of this trope. Notably when it comes down to it, Sandor doesn't trust her to Mercy Kill him instead trying to goad her into doing it out of anger and Arya leaves him to die alone despite his pleading.
    • Brienne with Sansa, who becomes friendly with Brienne after she rescues her.
    • Maester Luwin bonds with Osha — who was introduced threatening the life of Bran Stark — during the Sack of Winterfell while both are trying to keep Bran and Rickon alive. Before granting him a Mercy Kill, she promises him that she will keep the boys safe.
    • House Umber became close with the Starks thanks to fighting Wildlings together for centuries. Unfortunately this friendship is permanently destroyed by Smalljon Umber who betrays Rickon and gives him to Ramsay Bolton. Even though he is dead, the rest of his family will most likely be viewed as traitors.
  • Power Rangers:
    • Mighty Morphin' Power Rangers: Subverted. The main 5 rangers hadn't met prior to becoming rangers and wouldn't have met if they weren't, but all of them become friends because of it.
    • Power Rangers Dino Thunder: The three main rangers, high school seniors Kira, Ethan, and Connor are not friends to begin with. The three end up in detention together then become Dino Rangers becoming friends in the process. Cassidy Cornell mentions how weird it is that they are suddenly friends.
    • Power Rangers Megaforce has Gia and Emma who are best friends, Jake and Noah too, and then there's the new kid Troy. Them becoming rangers makes the five of them friends.
  • In Buffy the Vampire Slayer, this is how the Scoobies became friends. It is also the most common solution to any major strife among the Scoobies. A notable example is Xander and Spike in the final season. Despite openly hating each other until this point, they manage to work together to save the girls from the influence of RJ's magic jacket in 'Him'. After Spike goes back to save Xander from Caleb in 'Dirty Girls' their previous animosity is almost completely set aside. Perhaps the most prominent example is in "Dead Man's Party" during season 3. After just about everyone spends most of the episode trashing Buffy for running away to the point that she nearly runs away again, all is forgiven and they're all best buds again right after they stop a magic mask-induced Zombie Apocalypse.
  • Pretty standard for the heroes in Angel but Wesley and Gunn deserve special mention.
    Gunn: Come on, English! You know you my man!
    Angel: So, ah, I see you guys have bonded.
    Gunn: Happens when you fight shoulder to shoulder.
    Wesley: Or rather hip to shoulder these days.
    Gunn: This man took a bullet for me!
    Wesley: Ah, it was nothing!
  • Rome: Lucius Vorenus and Titus Pullo start out as enemies, but their various adventures together quickly turn them into the best of friends. The characters were based on two real life Roman centurions noted in Julius Caesar's journal for sharing a bitter rivalry and yet each saving the other's life in a single battle, making this trope Older Than Feudalism.
  • In the very first episode of Doctor Who, the Doctor doesn't really seem to like Ian and Barbara very much (the feeling is quite obviously mutual), but he's forced to work with them when the three of them (along with the Doctor's granddaughter, Susan) are captured by cavemen. They manage to win their freedom by showing the cavemen how to make fire. They go on to become very close friends. Their friendship was therefore, quite literally, forged by fire.
  • Firefly
    • Mal and Zoe, to a Platonic Life-Partners level. We don't see the exact moment of forging; rather, the war they were in together seems to have been a protracted forging process.
    • Mal and Simon. They rubbed each other the wrong way because of culture clash, suspicion, and the clash of their highly evolved Papa Wolf and Big Brother Instincts. But they learned to respect each other as the show progressed.
    • Jayne is a tougher nut to crack, but he and Simon also seem to have reached this point by the end of Serenity.
  • On Chuck, the members of Team Bartowski started out suspicious and paranoid of each other, but have grown into fast friends, saved each others' lives multiple times, and committed treason (and the occasional thoughtful felony) for each others' sakes.
  • Heroes: Peter and Sylar have some sort of bond in the realm of friendishness, after having spent five years together in an otherwise empty replica of New York City. Matt protests profusely, going as far as pushing a thought in Sylar's head to prevent him from leaving. Peter proceeds to defend him, although whether this was because he wanted to help Sylar or so that Sylar could save his friend Emma from helping destroy half of New York City (or maybe just Central Park — it was never very clear just how much of the city would be destroyed).
  • The West Wing: While the main cast were already like family before the assassination attempt at Rosslyn, the crisis, and the vigil over Josh can be seen as the moment where any loose ends locked into place. Most notable was Mandy's getting Brother Chucked without sharing the characters' ordeal.
    • In the fifth season Leo's commitment to this trope is put to the test when an old war buddy who saved Leo's life is brought up on corruption charges and Leo is faced with standing by his Fire-Forged Friend or doing the right thing.
  • Farscape — John Crichton and Ka D'argo. In the first season, D'argo tries to kill Crichton several times, and in episode 11 Crichton even says, "We're never going to be friends... We can be allies." After fighting side by side for a couple seasons, they end up being each other's BFF. To a lesser extent this became true of the rest of the crew on Moya over the years. Literally forced together through circumstance and picking up strays alongthe way, the group started out barely tolerating one another and seeking to advance themselves at the cost of the others. By the end, with the things they had suffered through together, even the most selfish like Rygel had gone through fire and blood for their friends.
  • Secret Diary of a Call Girl: Belle curses out Bambi when she finds out Bambi was stealing clients (and had found her generally annoying besides). After rescuing each other from punters who turned out to be psychopaths, they become good friends; Belle writes Bambi into her book, and later acts as her maid of honor.
  • Misfits is pretty much made of this trope. Although you could argue that even after being lumped together on community service, getting caught in a freak electrical storm and imbued with godawful superpowers, and then accidentally killing their probation worker and having to dispose of the body, the gang still don't particularly like each other, despite having formed a strange kind of bond.
  • Also defines Blake's 7 (not that any of them would ever admit it).
    Dorian: That's why I came for you. You care for each other. After what you've been through together, you couldn't fail to care for each other. Even you, Avon.
  • The Big Bang Theory: Sheldon and Leonard became friends when Sheldon saved Leonard from being blown up by rocket fuel that the latter had mixed incorrectly when trying to convert it to use in Howard's model rocket.
  • Babylon 5 provides an excellent example in the shape of Ambassador Londo Mollari of the Centauri Republic and G'Kar of the Narn Regime. Hating one another at first for reasons political (the Centauri had previously ruled Narn with an iron fist) and personal, the Centauri invasion of Narn space led at first to a bizarre convergence of interest and eventually a truly Odd Friendship as the series progressed. In the end, a prophecy Mollari had of G'Kar killing him came true in the oddest way imaginable: Londo, by now Emperor, trapped by a Drakh Keeper, has his trusted friend G'Kar kill him as part of a Thanatos Gambit to set the Centauri people to freedom and a bright future under Emperor Vir Cotto.
    • The Minbari and the humans culminating in an actual marriage between a Satai who voted for the Earth-Minbari war and Starkiller. Not to mention a human going back in time and becoming Valen, and the implication that the humans and Minbari would eventually take the place of the Shadows and Vorlons in guarding the still-younger races—although they would presumably they cooperate, seeing how bad of a job the Shadows and Vorlons did. Joining to fight off Ultimate Evil does that.
  • Air Crash Investigation: The passengers and crew of British Airways Flight 9 started their own club after their strange and nightmarish ordeal.
  • In Burn Notice, 2x13, Michael and Bly are dancing toward mutual destruction, when they end up caught in the midst of a bank heist. A few hijinks and a bullet wound later, they decide instead to do each other some favors and leave each other alone.
  • In Fi, Özge and Furkan become this over the course of the first season. She initially views him as a nuisance and treats him poorly, but he grows into her most trustworthy ally. His death and the circumstances surrounding it lead to her breakdown at the start of season two.
  • Star Trek:
  • In Sherlock, Sherlock Holmes and John Watson's relationship develops gradually over the first episode, and the familiar Holmesian friendship dynamic is fully established when John shoots the serial killer to save Sherlock's life.
  • At the start of Whitechapel, the detectives are a team but almost universally hate their new boss, DI Chandler, who thinks they're unprofessional slobs. Over the course of several stressful but revealing days together, he grows to respect them as real detectives and they decide he's not a such an asshole after all. That doesn't stop the insults, especially between Chandler and Miles.
  • The Vampire Diaries starts off with Damon and Stefan hating each others' guts, Elena's ex-boyfriend Matt disliking both of them, ... By the end of the second season they are one tight knit group, even the ones that should be mortal enemies like the werewolves and vampires. Each time they get closer, it is because of a stronger enemy. Even season 3s Big Bad seemed like this.
  • In Hell on Wheels Cullen and Elam have, as might be expected between an ex-slave and a former slave owner, a rocky relationship at the best of times. After Cullen saves Elam from a lynch mob and later on they fight and kill said mob when it pursues them they seem headed towards this.
  • Andromeda. Tyr and Seamus, complete with a Give Me a Sword moment during their Last Stand against the Magog.
  • Once Upon a Time: Red Riding Hood and Snow White become friends while hunting for The Big Bad Wolf. Snow finds out from Granny that Red herself is the wolf, and helps her stop Red before she unintentionally killed more people. In the fairy tale timeline, the next time we see them Red knows Snow's actual name (after Snow had given her an alias until she knew Red could be trusted) and is clearly helping Snow stay in hiding from the Queen. While we have yet to see what happened after Snow drags a confused, human Red away to protect her from hunters, they end up good enough friends that, during Snow's fight to save Prince Charming, Red (along with Grumpy) seems like she's practically Snow's Number Two.
  • Lost: The plane crash survivors don't always get along, but thanks to their circumstances (and hostility from the Others,) they realize they're in it together. The background characters are wholly apathetic, but the regulars are always going off to rescue each other despite the many dangers. Jack and Sawyer, in particular, hate each other, but still look out for each other against common threats. This is exemplified by their Survival Mantra; "Live together. Die alone." The Grand Finale really makes it explicit how the group had came to relate to each other as true companions, to the extent that none of them would "move on" from the flash-sideways universe until all of them were ready.
    Christian: [to Jack] The most important part of your life was the time that you spent with these people. [...] You needed all of them and they needed you.
  • Stargate Universe starts out far from this, with expedition members distrusting, framing, marooning and betraying each other (okay, so that's mostly two of them), and gradually develops into this. Young finally states this explicitly in the last episode, referring to the crew as a family.
  • The "seven stranded castaways" on Gilligan's Island. If one of them is in danger, the other 6 will rush forward to rescue them. If one of them is (always wrongly) believed to be dead, the other 6 will be beside themselves with grief. And while they may not be able to get off the island, they are adept at working together to survive whatever life-threatening obstacles are thrown their way. In the end, the answer to the often-repeated question, "Why don't they Just Eat Gilligan?" is obvious. Because they love him.
  • Smallville: Pretty much all of Clark's friends and loved ones (with the obvious exception of Lex, who goes dark) become this as the seasons go along. Pete becomes Clark's first Secret Keeper besides his parents, Chloe becomes Mission Control and an even bigger confidant than Pete, Lois goes from being Vitriolic Best Buds with Clark to being an integral member of Team Clark and the other half of a Battle Couple with Clark himself by the end, and Clark's superhero friends all end up interacting with Clark's non-powered friends and becoming their friends as well (even one-off character Andrea becomes Fire-Forged Friends with Chloe during the web/DVD extra "The Vengeance Chronicles"). It's no surprise that by Season 10, Team Clark basically feels like one big happy (though still occasionally dysfunctional) family.
  • NCIS saw Ziva's relationship with Team Gibbs unfold this way. Especially with Tony.
  • NCIS: Los Angeles Since Deeks was introduced Sam has at best tolerated his presence and Deeks doesn't like him much better. After the events of "Descent" in which both Deeks and Sam were tortured over stolen nukes, Sam has a much higher opinion of Deeks, given that Deeks didn't crack and give up Sam's wife as the undercover operative the Big Bad was seeking.
  • The original Battlestar Galactica: Sheba doesn't seem to very much like Cassiopeia, who was dating the former's father at the time. The two women then developed a newfound respect and friendship for one another after the attack on Gamoray that left Bojay wounded.
  • Friendships that transcend all social classes, between people who would do anything for each other, who share hardship as well as happiness and would be ready to die for each other is one of the major themes of Princess Returning Pearl.
  • On Marvel's Agents of S.H.I.E.L.D., May and Ward both are affected by an Asgardian berserker staff; the kind that brings up the worst memory of your life and turns it into Berserker Rage power. The power leaves after the fight is over, but the memories fade in time, approximately a decade. Since they are the only ones who can deal with it, they become FFF with benefits. Later, May thinks Ward is protecting her during a fight when he really knew she could take out the bad guy if he took the hit. He corrects her attitude by saying he isn't the kind of guy who "can't separate church and state."
  • Supernatural: Dean and Benny become this after fighting their way through Purgatory together. Originally starts off as Teeth-Clenched Teamwork on Dean's end, since he's not too happy about having to accept a vampire's help. It's only after Benny saves Castiel that Dean genuinely begins to like him.
  • In Person of Interest Root and Reese start off as enemies, as a result of the fact that Root had played him and kidnapped Finch. On her part she thought of Reese as Dumb Muscle and wanted to replace him as Finch's partner. After she joins the team, as an agent of The Machine they become allies. The friendship part doesn't happen until Shaw apparently dies while they are saving the Stock exchange. They two of them go on a crusade across five states, even picking a fight with government operatives just on a hunch that they could save her.
  • Considering the core team of Leverage is made up of loner consummate criminals (except Nate), none of them exactly trust each other even when brought together by an Enemy Mine situation. But after that first addictive job and discovering that Good Feels Good, they decide to stay a team, trusting and relying on each other to balance out their own flaws. It takes a lot of fire and explosions, but through their work they grow as close as family.

    Multiple Media 
  • Most BIONICLE characters who become Toa are strangers at the start but become friends or at least trustworthy allies during their adventures and fights. Most notably, Tahu and Kopaka practically couldn't have been more different, and a lot of time was dedicated to their petty disputes, but at the end, Kopaka came to regard Tahu as a leader worthy of respect. The close friendship between Takua/Takanuva and Jaller is also this, as they only got so close during their exploits in the Bohrok Wars. Matoro might be the saddest example — not long after he came to regard his teammates a friends, he had to perform a Heroic Sacrifice.

  • Officer Eiffel and Commander Minkowski from Wolf 359 grow into this. Especially impressive when you consider how flagrantly antagonistic their relationship was during the first episodes of the series.

    Professional Wrestling 
  • The Nexus. Originally, they were rookies on WWE's NXT show, and were thus, competing against each other for a WWE contract. However, they all came to loathe WWE management as they forced the rookies to do humiliating challenges like obstacle courses and keg carrying contests, as well as constant rule changes and unchecked abuse from certain WWE pros that were supposed to be mentoring the rookies. This led to the Season 1 winner Wade Barrett uniting all the Season 1 rookies and leading an assault on Monday Night RAW until all eight seven rookies ended up with contracts.

    Tabletop Games 
  • One possible backstory for Chaos warbands in Black Crusade: the warriors have survived this long by sticking to each other, and would do anything to keep each other alive. Of course, this being 40K, an equally likely one is each warrior viewing the rest of the warband as walking meatshields until they can be sacrificed to obtain power from the Dark Gods.
  • Magic The Gathering: The original four members of the Gatewatch were four planeswalkers with very different personalities who came together to fight the Eldrazi, only to discover that they made a surprisingly good team. Since the Eldrazi are far from the only threat in the multiverse they decided to form The Team.

  • William Shakespeare has Henry V claim this in his Rousing Speech — but he doesn't actually manifest such friendship toward his soldiers after the battle.
    • The quote at the top of the page is exactly the same as alludes to this bit from the St. Crispin's Day speech:
      Henry V: We few, we happy few, we band of brothers;
      For he to-day that sheds his blood with me
      Shall be my brother; be he ne'er so vile,
  • Cyrano de Bergerac wonderfully subverts this: Cyrano and Christian’s friendship is not born because they fight against the same enemy, but because they are courting The Ace Roxane, from whose rejection both of them are terribly afraid and must gather all their courage only to face her.

    Video Games 
  • Dom and Marcus of Gears of War were already good friends at the start of the Pendulum Wars, and it escalated to the point that they consider themselves brothers by Gears of War 3. However, this pales in comparison to their friendship with, Anya, Baird, Cole, then Sam, then... it's a lot of people. Surviving a war against Absolute Xenophobes will do that to you.
  • In Jak II: Renegade, the original group of four was expanded to eleven when they meet Torn, Ashelin, Sig, Tess, Pecker, Onin and Brutter throughout the course of their stop-the-Baron fight.
  • The Survivors of Left 4 Dead are a group of strangers that happen to be immune to The Virus that produced the Infected and caused the Zombie Apocalypse. In order for them to survive and reach safety, they must work together as a team, fighting through the zombie hordes and sharing their limited medical supplies.
    • In the Tie-in Comics, Louis even admits "I love you guys" when it looks like they aren't going to make it.
    • By the second game, you can actually watch their friendship unfold through the journey.
  • Marisa and Reimu of Touhou, who have fought together (and each other) since the second game, consequently forging one of the series closest, most persistent friendships. They later form similar friendships with Sakuya in Perfect Cherry Blossom, several youkai in Imperishable Night and most recently Sanae in Undefined Fantastic Object.
  • Part of Khelgar's loyalty quest in Neverwinter Nights 2 revolves around getting him, Neeshka, and Elanee to become this.
  • The second Tales of Fandom game seems to indicate this kind of backstory for Tales of Symphonia characters Kratos and Yuan, who started out as opposing knights of two warring countries.
  • The main cast of Tales of the Abyss definitely counts. Contrast the first third of the game, when Luke destroys Akzeriuth, to the last third of the game, when Anise betrays the party and directly causes Ion's death. In the first case, the party condemns Luke's immaturity and irresponsibility, abandons Luke in Yulia Citynote  and only rejoins with him once they're absolutely forced to. Then, twenty hours of gameplay later, Anise is almost instantly forgiven for her crime, and the entire party agrees to stand by her side for her duel with Arietta. Considering how much betrayal, murder, crisis and conspiracy they've all had to deal with, it's no wonder they've come to rely on each other. It says a lot that one of the party members is a borderline sociopath, and yet he still manages to learn of the Power of Friendship after all is said and done. In fact, he puts their situation best:
    Jade: I don't know about "friends," but we do have an awkward bond of sorts.
  • Tales of Vesperia implies that Yuri and Flynn are Childhood Friends, but the prequel movie sets them more under this trope. They're butting heads constantly until they save each other's lives a few times and watch their beloved captain die.. In the game itself, Brave Vesperia falls under this trope - they go through a lot, but by the end, the guild is as tight as any family.
  • Tears to Tiara 2. As Elissa and Daphnis blows their own cover and rise up, about to fight the slavers to the death, Hamil and the Party blows their own cover and join in the fight. The latter is the leader of La Résistance and the former are trying to from an alliance with them to resist The Empire. So it's this on two levels.
  • In Super Smash Bros. Brawl, Marth and Meta Knight are both standing near the same giant blob of Subspace. Meta Knight assumes the worst and attacks Marth, who defends himself, until some Primids attack, at which point they both turn on the Primids and realize they're on the same side. They work together for the next leg of the game.
  • A number of characters have been enemies or opponents of Sonic the Hedgehog, but are now friends/allies to him.
    • Sonic and Knuckles start off as enemies due to Eggman's manipulations, but after Knuckles realized Eggman's lies, the two became close friends, despite the two still clashing on occasions.
    • At the beginning of Sonic Adventure 2, Sonic and Shadow were both bitter rivals. By the end, however, they become allies. Much like Knuckles, though, the two still go at it from time to time.
      • Shadow also plays this with Omega in Sonic Heroes. Even though both became teammates after Rouge encouraged them to team up with her to find Eggman, the two didn't get along well since their brief fight. As time goes on, the two have become reliable allies.
      • Shadow does this with Rouge as well, to a degree. They were on the same side in Sonic Adventure 2, but Shadow then found out that Rouge wanted to find the Chaos Emeralds for herself and to get more jewels from G.U.N. after she finishes her research on Project Shadow. They don't really interact after that because of Shadow's supposed death, but Rouge holds onto one of Shadow's limiter rings, until she finds him again in Sonic Heroes. Since then however, Rouge and Shadow have become very close to True Companions, with a little Ship Teasing involved.
    • This happens again in Sonic Rush with Sonic and Blaze. Blaze was so determined to find the Sol Emeralds alone, she didn't want Sonic's help (and by extension his other friends). By the end however, Blaze realised that friendship is what it took to make the Sol Emeralds work, and she and Sonic defeat Eggman and Eggman Nega together. This friendship isn't without some little ship teasing either.
    • Sonic and Silver in Sonic the Hedgehog (2006). Silver wanted to kill Sonic because he believed him to be the Iblis Trigger, but realizing Mephiles' lies, the two begin to work together in saving Princess Elise from Dr. Eggman. Then this trope is played again due to the events of Sonic '06 being erased and Silver clashed with Sonic again in the Sonic Rivals series. It wasn't until Sonic Colors DS that the two got along again.
      • To a lesser extent, this happens with Shadow and Silver too. Shadow rescues Sonic from Silver about to kill him, and fights Silver in Sonic's place. Then, after a mishap with Chaos Control and some other confusions, Shadow and Silver team up to stop Mephlies and Iblis in the past, thus getting along after that. Like with Sonic however, Shadow clashes with Silver again in Sonic Rivals due to the Retcon, and it takes longer for them to get along.
      • There's also Silver and Espio in Sonic Rivals 2. Initially, their first meeting was iffy, then they teamed up, and at the end of their story, they become respectful towards each other.
  • In Class Of Heroes, The more your team fights and preforms gambits together, the higher their affinity (bond) becomes.
  • In the beginning of most Final Fantasy games, the team are people thrust together but eventually become this over the course of their hardships.
    • In Final Fantasy VI the first time Cyan mets Celes he has to be talked out of killing her. After a number of things happen he is glad to see her after they have been parted for a while.
    • Final Fantasy VII has a cold hearted mercenary, an eco terrorist, a buxom bartender, a flower seller, an animal who acompanies the team because they're going the same way, a fortune-telling robot riding a stuffed teddy, a pilot who joins because he has nothing better to do, (possibly) an immortal gunman and a perky ninja chick (...What a crew). The sequel even has Cloud call them nakama (Japanese word for "friends").
    • Final Fantasy VIII has the cold team leader, the cheerful guy he can't stand, their former teacher, the unpopular transfer student, a freedom fighting-princess like girl and a cocky gunman. In the end Squall falls for Rinoa, warms up to the others and shows signs of trusting Zell as a completely competent second, regardless of difficulty.
    • Final Fantasy IX has one of these moments with General Beatrix after she defeats you for the third time. She then realizes she was being used and buys the party time to escape. General Steiner and Freya remain behind with her to cover the parties escape. These were two of the characters in your party when she stomped you not five minutes ago. Freya had both of her hometowns destroyed by her in the last 48 hours.
      • Zidane says that they're "more than friends - we're a team"), even though most of the characters (namely Zidane & Steiner) don't get along with each other at first. When Zidane discovers his disturbing origin, he tries to leave the gang. Garnet/Dagger, however, convinces him that they'll stay with him no matter what.
      • Hell, at that time, even Steiner flat-out declares that he will not abandon Zidane, no matter what.
    • Final Fantasy XIII has everyone at each other's throats from the start. Hope wants Snow dead because Snow caused his mother's death, Sazh tries to shoot Vanille (at her own request) before turning the gun on himself, Lightning hates Snow for threatening to take Serah away from her, and Fang demonstrates that so long as it would guarantee Vanille's safety, she'd set the world on fire and watch it burn.
  • Garlot and Leon in Blaze Union, a pair of knights who have both been screwed over by the corrupt political system—Garlot growing up as one of the country's much-abused peasants, and Leon having his face scarred and losing his job and standing as an Imperial guard after his parents were executed as scapegoats to prevent a national crisis. The two of them meet, Leon picks a fight, and his shock and humiliation after losing cause him to become positively obsessed with defeating Garlot. One offer of employment from another of Garlot's enemies, many more battles, a realization that Leon is being used, an emotional final confrontation in a burning city, boatloads of Foe Yay, and a race against time on Garlot's part to save Leon later, they are steadfast friends and teammates.
  • James Raynor and Horace Warfield in Starcraft II hated each other at first, because Raynor was a "pirate" and a "terrorist" and because Warfield was a Dominion general. When the two of them led their attack on Char, and Raynor pulled off a Big Damn Heroes move to save Warfield and his men, Warfield warmed up to Raynor.
    Warfield: "You may be a damned pirate, Raynor, but, whatever happens, you saved my boys today... and I won't forget that."
    • The same could be said of Tosh, although it depends on your choice in the game. All of Raynor's Raiders seems to be this too, as they're all volunteers apparently, as well (to a degree) Tychus.
    • In the first Starcraft Raynor was valuable ally to the Protoss, especially with Tassadar, Zeratul, and Fenix, and was instrumental in the Overminds destruction.
  • Halo:
    • Halo 3 had the most recent Arbiter, Thel 'Vadam, join forces with Master Chief John-117. At first they start out quite hostile towards each other—Chief even shoved a gun right in Arbiter's mandibles, but by the end they trust each other enough to pull a Back-to-Back Badasses, and frequently save each other in battle. That and Arbiter is the only one who believes John has not died at end of the game—who is, in fact, stuck floating in space, with no way to get home, and his AI Cortana quickly approaching rampancy. Don't mind me, I'm just sweating from my eyes.
    • Humanity and the Forerunners, who had historically been at each others' throats (respectfully for the most part, but still), become this following the firing of the Halos. After spending the entire Forerunner Saga being Fantastic Racists towards each other (humans being "primitive, bloodthirsty animals" and Forerunners "meddling, high-and-mighty Abusive Precursors), both come together to mourn the unimaginable losses they've suffered.
  • Beyond Good & Evil has Jade and her second partner, Double H. Initially, they work together simply because they're both on the same side and there's really no one else around; while they don't actively dislike each other, Double H's mania is mostly one-sided. They start to become friends in earnest after Jade saves Double H's life yet again, with their bond ultimately cemented during a Take My Hand moment.
  • Persona 4's Investigation Team is composed of individuals who, with the exception of long-time best friends Chie and Yukiko wouldn't have much to do with each other, but become close friends with one another. It's certainly helped by the fact that part of the plot revolves around defeating each others' out-of-control suppressed feelings, and in the process, realizing each other's deepest secrets.
    • Persona 3's S.E.E.S. also shows shades of this, given Yukari's initial distrust and contempt for Mitsuru (she held the Kirijo group responsible for her father's death) and Ken's desire to kill Shinjiro and then himself out of revenge because Shinjiro accidentally killed his mother. By the end, though, Yukari and Mitsuru become best friends, Ken lets go of his hatred for Shinjiro, and the group becomes a cohesive team.
    • This also happens with the Phantom Thieves of Hearts in Persona 5, especially with Makoto. She's initially on bad terms with the Phantom Thieves, since they (Ann in particular) accuse her of turning a blind eye to Kamoshida's abuse of the students, and Makoto later blackmails them into taking down Kaneshiro, a Yakuza boss who's threatening students. After Makoto inadvertently ends up getting the students into trouble with Kaneshiro, she helps them begin the infiltration of his Palace, and saves their lives by awakening her Persona. Afterwards, she quickly becomes accepted as part of the team.
  • The party in Mass Effect 2 is pretty much this trope. The members are very different from each other, from very diverse walks of life. Heck, there are even a few disagreements that threaten to tear them apart. But in the end, if Shepard is a good (and consistent) leader, the entire party will make it out alive, thanks in no small part to watching each others' backs during the Suicide Mission.
    • The most blatant example of this is Joker and EDI. They spend almost the entire game bickering at each other until The Collectors take over the Normandy while Shepard and the rest of the party are away leaving them the only ones to stop them. After that incident they treat each other as equals (most noticeably, while prior to the incident they referred to each other as "Mr. Moreau" and "It", afterwards they switch to "she" and "Jeff"). In the third game, thanks to EDI acquiring a new robot body they can possibly have a Relationship Upgrade.
    • Mass Effect 2 plays this in an interesting way. In one team you have a human WMD wrapped up in a dangerously sadistic sociopath, a turian who manages to single-handedly become an Enemy Mine for three warring merc groups, one of the homicidal robot Mooks from the first game, a deathly (and deadly) ill drell assassin and essentially a living avatar of asari justice/Death by Sex (depending on your decisions). If it weren't for a greater threat, most of these characters would probably never be in the same room as each other without trying to kill each other. After the suicide mission, most are on at least cordial terms (except Jack, who is still a bitch, but got a little better).
    • This carries forward to Mass Effect 3 with Tali'Zorah and Legion. Tali, a member of the race that created the geth and have been incredibly bitter about the whole affair (and whose father is killed by Geth just before her loyalty mission in 2), admits to having come to truly trust Legion, and explains that they have had a great impact on her preconceptions of the geth. Tali is one of the greatest advocates for Geth-Quarian peace by the end of the Rannoch mission. All because a geth decided not to start shooting at her but at her foes.
    • The Citadel DLC in Mass Effect 3 really drives home the point that the entire Normandy crew has become this because of Shepard. It ends with a party with every surviving member of Shepard's squads across the trilogy in attendance. Even characters who never served at the same time bond over their shared experience fighting alongside Shepard. You even get a War Asset from it.
    • The krogan and turian forces during the fighting on Palaven in 3. The krogan are initially there as the price of having the genophage cured; the most important surviving turian military HQ is on the moon the krogan reached during the Krogan Rebellions that led to the genophage; they have very different fighting styles, social structures and traditions; and they don't like each other very much, to the point where Warlord Okeer's imprints for his tank-bred krogan included a shot of a krogan pulling off a dead turian's face with a crowbar; but a while after you bring them together, you get a codex report of the "Miracle of Palaven", which has both krogan and turian forces cooperating and sacrificing their lives to pull off a coordinated and devastating strike on the Reaper forces. It's possibly the largest defeat the Reapers endure before the endgame. And it's pulled off by two peoples who couldn't stand each other, but have learned to get along through their shared battle against horrible space-thulhus and their armies of cyborg zombies.
    • Javik, a reawakened Prothean, has a lot of Fantastic Racism against the younger races, and quite often gets into arguments with Paragon Shepard in particular about their idealism in the face of a Hopeless War. By the end of the game, it's quite clear that he has come to respect Shepard a great deal. It definitely comes across as mutual.
  • In Jade Empire, Dawn Star and Silk Fox often argue, but gain respect for each other after fighting together while Kang blows up a bridge.
  • In Sabres of Infinity, your fellow officers, Elson and Cazarosta, may come to view you as this if you maintain good relations with them.
  • Squad 422 in Valkyria Chronicles III. Since all of them are convicted criminals, each squad member can't give half a damn if the other guy eats a whole serving of gatling gun barrage. But due to Kurt's compassionate nature and the kind of crazy situations the squad have to go through, they slowly become an example of this trope. When Kurt calls for their aid for one last job after the war is over, all of them answer.
  • In Might and Magic: Heroes VI Duke Slava forms an Enemy Mine alliance with Kraal, an orc warrior, against Toghrul, a shaman who betrayed Kraal's people and has a grudge against Slava's family. One short military campaign and several debates about religion and philosophy later, Slava considers Kraal enough of a friend to offer him several hundred acres of his own land for Kraal's people to settle on.
  • Caim and Angelus in Drakengard. They hated each other before and after they made their pact, but as they fought together, they started actually caring about each other. The fight against the Wyrm cements this, as Angelus starts feeling "strange new emotions" for Caim, and thanks him for making her stronger than she was before. Afterwards, Angelus tells Caim to not die during their fight with Manah, and becomes the Seal due to her wanting to protect Caim.
  • BioShock Infinite gives us the Booker DeWitt and Elizabeth, the two main characters. Oddly enough, their relationship starts out rough but all right, then deteriorates when Booker lies about taking Elizabeth to Paris, and Elizabeth states the only reason she trusts Booker is because he's the only way out of Columbia. Their relationship becomes a lot better when Booker consoles Elizabeth about her tears causing Chen Lin's death, and after Elizabeth kills Daisy.
  • The Shadow Hearts series has a few of them. In the first game, the three main characters don't really get along: James tends to grate on Koudelka's nerves, and Edward can barely keep the peace, but they have each other's backs in fights. In the second game, Yuri and Zhuzhen constantly fight with each other constantly. Yuri and Margarete also have their moments, but they constantly work with each other, and Margarete even looks up to Yuri.
  • On a slightly minor scale in Psychonauts with Raz and Lili. Raz is friendly toward most campers, but Lili is a bit cold and belittling toward him. When the two realize that they're both having the same prophetic dream due to Oleander's psychic interference, they work together to get to the bottom of it and are a lot more tolerant of each other by the second act of the game.
  • Sakura Wars 3: When they meet in Episode 7, both the Paris Combat Revue and the Imperial Flower Combat Troop spend quite a bit of time butting heads, even getting into a dance competition in an attempt to prove which is better. However, after they work together to stop Ciseaux and his flunkies from destroying the Eiffel Tower, they become good allies and friends (though the fact that the judges of the aforementioned dance competition decided that both groups of girls won probably also factored into it).
    • Sakura Wars: So Long, My Love gives us Shinjiro Taiga, who was treated rather harshly by Cheiron Archer and Subaru Kujo upon first joining the New York Combat Revue. As he fought alongside them and helped them overcome their personal woes, though, they became good friends, comrades-in-arms, and potential love interests.
  • Applies to Pit and Dark Pit in Kid Icarus: Uprising. Dark Pit is the Evil Counterpart of Pit and has no sympathy for him. However as the story progresses Dark Pit comes out to help Pit on several occasions (facekicking the Underword Guardian and blasting open the portal to the Chaos Vortex come to mind), they save each other's lives on specific occasions and even do a perfectly executed pre-asskicking speech on Dark Pit's own invitation. All in all it seems they have come to like each other.
  • In Fleeing the Complex from the Henry Stickmin Series, Henry and Ellie become this on the path to the convict allies ending. They start off as complete strangers to each other who only share the fact that they're convicts who happen to be in the same holding area. After starting full scale a prison riot and getting to the surface, they get on a motorcycle to escape, but the warden tackles Henry off of the motorcycle. At this point, Ellie could've just left Henry to his fate, but she decides to turn back to save Henry by whacking the warden with a stop sign.
  • It's common in The Legend of Zelda for Link to to ally with someone who doesn't think much of him, but of course, draws closer to him throughout the game—Tatl in Majora's Mask, Tetra in The Wind Waker, Ezlo in The Minish Cap, Midna in Twilight Princess, Linebeck in Phantom Hourglass, Groose in Skyward Sword, and Zelda herself in Breath of the Wild.
  • In the first Kingdom Hearts game, Donald is more or less a Jerkass who doesn't give a care about helping Sora find his missing friends, and only tells him that they'll find them to make him comply. By Deep Jungle, the two are at each other's throats when Sora finally realizes that he was only being used. Fortunately, the two start to get along as the game continues on, and by Hollow Bastion, Donald chooses to stay by Sora's side to protect him despite the King's orders to follow the one with the Key, which is Rival Turned Evil Riku at this point.
    • Similarly, Ratchet & Clank follow the same path as Sora and Donald, in that they start off on good terms before Umbris, where they are suddenly at each other's throats over Ratchet's desire for revenge against Captain Qwark, and Clank just wanting to stop Drek from tearing planets apart. The two stop fighting after Ratchet finally completes his revenge, but at the cost of them not being able to protect a city from being attacked, and eventually grow to become best friends.
  • Phoenix Wright and Maya Fey were introduced under some pretty awful circumstances: Maya had been accused of murdering her older sister, and Phoenix was the only attorney willing to defend her. Though they became best friends pretty quickly following Maya's acquittal, that was only the first of many times they would fight by each others' side.
    • Perhaps more fitting of this trope are Phoenix Wright and Miles Edgeworth. Childhood friends turned bitter courtroom rivals, these two spend the first game doing little but insulting and arguing with each other. It isn't until the end of the second game, when Edgeworth returns from faking his own suicide/finding himself, that he and Wright finally begin to cooperate.
  • In The Elder Scrolls Backstory, most prominently seen in Morrowind, the ancient Chimeri/Dunmeri hero Lord Indoril Nerevar had one of these with Dumac Dwarfking, leader of the rival Dwemer. The two formed an Enemy Mine when Morrowind was threatened by the invading Nords, and the two became close friends after. Dumac even attended Nerevar's wedding and gave True Flame as a gift to Nerevar. It wouldn't last though, as the Naytheistic Dwemer discovered and attempted to tap into the Heart of Lorkhan, which the devout Daedra-worshipping Chimer saw as a blasphemy. The two went to war and, while exactly what happened next is recounted differently by the surviving parties, the Dwemer disappeared and Nerevar was slain.
  • This is pretty much the entire basis of the idea behind support conversations in Fire Emblem. By having two units stand near each other (and in modern games, engage in battle with each other) causes them to gain some affinity for each other and eventually support, possible even leading to marriage.

  • Raimi and Oran of Broken Saints are from completely different parts of the world, have completely different outlooks on life, and certainly get off to a rocky start, but by the Grand Finale, it's clear they're destined to be Heterosexual Life-Partners.
  • Done on a massive scale in the spoil fanfiction Enemy of My Enemy, where what starts as a tense Enemy Mine situation soon leads to humans & Elites fighting together like brothers. A good example is Flight Officer Perry and Helmsman Zuka.
  • From the Global Guardians PBEM Universe: Majestic, a hero team sponsored and sanctioned by the British government, was originally a group of perfect strangers from all parts of the British isles, brought together by the government quickly and with no warning in response to an attack by the subterranean Lemurians. The experience made them a true team. Later, the team would move from this to a true Band of Brothers while fighting off the super-terrorists known as Jihad.
  • Each team in Red vs. Blue starts off the mortal enemy of the other team, and most people on the same team don't like each other either. As the series progresses, though, they wind up having to help one another through a lot of difficult spots, to the point of coming to each other's rescue.
  • The titular team of RWBY formed in spite of their own disagreements or distrust of each other. Weiss viewed Ruby as an idiot, Ruby viewed Weiss as a stuck up jerk, Blake was standoffish and Yang was trying to force her sister Ruby to make new friends. Fighting a giant flying monster helped to bring them together a lot, though not completely.
    • Ozpin, the principal of Beacon, may be invoking this trope, actually. As the test they were in was meant to form teams, throwing them into a place filled with fearsome beasts that would require teamwork to take down is an efficient way.
  • The Mall Fighters in Mall Fight all ended up as this, one way or another.
  • The Power Trio of Brennus met this way, fighting the Snow Queen together.

    Western Animation 
  • Delta State, Martin, Luna, Claire and Phillip do not know each other well at first and it shows due to them snarking at each other more, as time goes on, they become quite close to each other. This is also true for Brodie, as the others had to learn to trust him.
  • Justice League, "The Terror Beyond": Solomon Grundy fights against the Eldritch Abominations alongside the League, and strikes up a friendship with Hawkgirl in particular. He gets mortally wounded fighting Ichthultu and indirectly rescuing Hawkgirl. She comforted him in his final moments. Hawkgirl still considers him a friend in the much later episode "Wake the Dead".
    Solomon Grundy: Bird-nose help Grundy? But Bird-nose and her friends hate Grundy.
    Hawkgirl: Grundy help Bird-nose, Bird-nose help Grundy, okay? Excuse me, Hawkgirl smash.
    • In the first episode this is the way the league is formed.
  • Subverted in the second season finale of Megas XLR. After the Glorft commander and Coop work together against Coop's evil alternate universe self, the Glorft commander extends his mech's hand in friendship. Just as Coop is about to accept, he trips in his giant mech, and because of that activates a weapon that destroys most of the Glorft's mech army. Naturally, the friendship is called off.
  • Optimus Prime and Sentinel Prime of Transformers Animated. Since Sentinel is a Jerkass to the nth degree, this trope is more or less the only thing keeping them friends.
  • Avatar: The Last Airbender: Aang and Zuko are literally Fire Forged Friends, since both of them can firebend. Unlike typical instances of this trope, their progression from enemies to allies was more gradual, involving several battles where they ended up saving each other. It basically went like this:
    • Up until "The Blue Spirit," Zuko had been single-mindedly pursuing Aang, because he believed he had to capture the Avatar in order to restore his honor. Once Aang was captured by Zhao, however, he knew that all his hopes would be ruined if he didn't do something. Not one to take things lying down, Zuko disguised himself as the Blue Spirit and helped to liberate Aang from his prison, with the ulterior motive of capturing the Avatar himself once they escaped. Near the end of the episode, Aang asks Zuko if he thought they could have been friends had circumstances been different.
    • In "Siege of the North, Part 2," despite Zuko having battled with Katara and knocked her unconscious before absconding with Aang's body while he was in the Spirit World, Aang refuses to leave Zuko out in a blizzard to die. This allows Zuko to escape with his uncle.
    • Almost an entire season later, in "Lake Laogai," Zuko frees Appa from the Dai Li, enabling Appa to swoop in at the last minute in a Big Damn Heroes moment, saving the Gaang. It was at his uncle's insistence, but still, he's the one who made the choice.
    • In "The Crossroads of Destiny," Aang and Iroh team up in order to save the people dearest to them, Katara and Zuko, who are being imprisoned by Zuko's younger sister, Azula. This was supposed to mark Zuko's Heel–Face Turn, but Azula convinces him to join her side with the promise of securing their father's love, which was the one thing Zuko always (thought he) wanted. This delayed the "friends" part for over half of the following season.
    • Finally, in "The Western Air Temple," Zuko, having stood up to his father and proudly declaring that he is going to join the Avatar and his friends, tries to do so, offering to teach Aang firebending. They completely reject him. Near the end of the episode, he proves his intentions are true by helping to save them from Sparky Sparky Boom Man Combustion Man, the assassin that he hired at the beginning of the season. When Aang sees that Zuko understands what a tremendous responsibility he has vowed to take on, he seals their friendship with: "I think you are supposed to be my firebending teacher."
    • Similarly, Zuko's going on "field trips" with Sokka and Katara, to break their father out of prison and find their mother's murderer, respectively, help them overcome their distrust out of them.
  • Code Lyoko: in the beginning, the kids weren't very loyal to each other, and worked more like a team of convenience than friends. They never hesitated to kick someone out of the group when they crossed a line, such as when Ulrich used the Time Travel program to cheat on the lottery, and when XANA convinced them Jérémie was toying with their safety. In fact, XANA's plots frequently involved trying to break the team up, and worked quite well each time, for a while. Played straight later on thanks to Character Development, things have changed, especially in the Season 2 finale. On the up-side, this provides a pleasant break from The Power of Friendship message that's reiterated Once an Episode in most Five-Man Band shows. It's worth noting that before coming together as a team, Jeremie and Yumi were friendless social outcasts and Aelita was trapped in a computer for ten years. Although the fact they're doing it all to help Aelita in the first place brings them right back into Power of Friendship territory. As the flashback episode shows, the reason they are antagonistic to Sissi is because she betrayed that trust. Otherwise, she might be a part of the group or at least a Secret Keeper.
    • The group's status as this is cemented in the finale of the original series when Jeremie confides in Yumi that the reason he doesn't want to shut off the computer despite having defeated XANA is because he fears the rest of the group abandoning him; she's immediately sympathetic at this reveal as opposed to her earlier irritation and reassures him that that will never happen.
  • Samurai Jack: Jack and the Scotsman first meet halfway across a ridiculously long (and thin) bridge, each man going in the opposite direction. A fight breaks out as they try to decide who should turn back first to let the other cross, before they are set upon and chained together by bounty hunters. The resulting Enemy Mine results in a rather strong friendship, and they meet again a few times through the series to engage in some Back to Back Badassery.
    • Season 5 has Jack with Ashi, one of the Daughters of Aku who tried to kill him.
  • My Little Pony: Friendship is Magic:
    • Twilight Sparkle initially doesn't want anything to do with the five quirky ponies who want to be friends with her. Even the fact that they're all willing to accompany her through The Lost Woods just makes her cringe. However, the ensuing adventure helps her connect with them and actually start regarding them as her True Companions.
    • This also applies to the rest of the main case. Although they previously had a broad knowledge of each other's existence, with some of them even explicitly shown to have a prior connection (like Rainbow Dash and Fluttershy having gone to the same summer flight camp), many of them (like Applejack and Rarity) would probably not have been friends before the events with Nightmare Moon.
  • Averted in the "Mountain of Madness" episode of The Simpsons, in which Homer and Mr. Burns are trapped together in a cabin by an avalanche, when Mr. Burns says, "...once you've been through something like that with a person, you never want to see that person again."
  • Early in the first season of ReBoot in the episode "The Tiff", Bob and Dot get into an argument so bad that they both refuse to ever see each other again. Their friends panic that Bob might leave Mainframe so Enzo enacts a series of Zany Scheme meant to get them to either apologize or invoke this trope, failing utterly on both counts. Eventually they get trapped together in a game, the trope taking full effect and their teamwork saves both the day and their friendship (to say nothing of their unresolved sexual tension)
  • In Josie and the Pussycats, the Pussycats, their manager, and roadie towards Alexandra.
  • Ilana and Lance are this in Sym-Bionic Titan. While Octus is more willing to cooperate with them, they hardly know each other at the beginning of the show and conflict with their battle methods in the third episode. It's Octus teaching them how to cooperate, then defeating Mutraddi together that allow them to get along much better.
  • In the Thomas the Tank Engine episode "Down The Mine", Thomas and Gordon become one after Gordon helped Thomas from the mine accident, and when the two engine realized that they are in disgrace for their misbehavior (Gordon had fallen into a ditch after refusing to pull trucks, which Thomas teased him about it previously on said episode). This is even intriguing considering the two engines had a disagreement in "Thomas and Gordon", the pilot episode. In "Paint Pots & Queen", Gordon even reminded Thomas of their alliance as the two returned to the sheds.
  • Duncan and Beth become friends in the Grand Finale of Total Drama Action.
  • Steven Universe: All of the Crystal Gems' Sixth Rangers go through this. Lapis Lazuli and Peridot start out as enemies (albeit sympathetic ones) who were opposed to the team, Connie Jumped at the Call but had to go through a ton of harsh training to even be allowed on a single mission, and Lars despised Steven until a near-death experience on Homeworld makes him realize what a jerk he'd been to everyone.
  • Zeb and Kallus begin Star Wars Rebels as bitter enemies, each harboring deep resentment over the conflict they fought in on Lasan. When circumstances force them to work together, they develop a degree of respect of one another. Then Kallus pulls his Heel–Face Turn and the two are once again forced to work together. Over the next two seasons, they grow closer, and by the time of the series finale they’ve effectively become Heterosexual Life-Partners. Notably, when the rest of the Ghost crew goes their separate ways, Zeb and Kallus instead stick together and head off to Lira San.

    Real Life 
  • The Spartans encouraged soldiers to have a good friend so that they'd fight harder to protect them. And if they died, hopefully they'd go Ax-Crazy in a quest for vengeance.
  • The Thespians refused to retreat from the Battle of Thermopylae, fighting alongside the Spartans in their final stand. The Spartans marveled at this; Spartans were raised as warriors and expected to lay down their lives on command, but the Thespians were volunteer soldiers, mostly farmers and tradesmen. The Spartans saw the Thespian's willingness to sacrifice themselves as a kind of courage beyond even their own, and were very proud to have such allies in their last moments. The world has not forgotten.
  • The Sacred Band of Thebes consisted of 150 pairs of male lovers under the theory that a man would fight harder in the presence of his lover, so as not to be disgraced. The Sacred Band was tough enough to win repeated encounters with the Spartans but was ultimately defeated at the Battle of Chaeronea in 338 BCE (read: killed to the last man) by a force led in part by a young Alexander the Great in his first appearance as a military commander.
  • Centurions Lucius Vorenus and Titus Pullo. You know, the pair who became incarnated in HBO's Rome series, except Titus Pullo got demoted to a mere career legionary. In Real Life, an incident is documented in Gaius Julius's memoirs of his Gallic ventures, where the two men who were fierce rivals ended up fighting off a large group of enemies, taking turns to rescue each other, to the cheering of the legion.
  • Although not a life threatening situation, the cohesion formed by working to achieve superordinate goals (a superordinate goal is a desire, challenge, predicament or peril that both parties in a conflict need to get resolved, and that neither party can resolve alone) was the key of the third phase of the Robber's Cave Experiment, information can be found here, and here.
  • LA Lakers basketball players Kobe Bryant and Pau Gasol. Their friendship is forged by playing basketball together in the NBA, but was most apparent when they were opponents in the final match of the 2012 Olympics- Kobe as captain of the US team and Pau as superstar of Spain's team. After the US won, the two immediately gave each other a long, tight hug.
  • Louisiana Senator Judah Benjamin challenged Senator Jefferson Davis to a duel on the Senate floor over a perceived insult. The men worked out their differences without violence and became friends. When the South seceded, Confederate President Davis appointed Benjamin to three different cabinet positions in his government. Benjamin thus became the first Jewish cabinet member in a North American government.
  • Dale Zelko and Zoltan Dani
  • A significant part of military training is to get recruits into this mindset, often by having their instructors play the role of mutual opponent.
  • A lion, tiger, and bearnote  were under the care of an abusive drug dealer when they were cubs. After they were rescued, they proved to be inseparable and still live and play together twelve years later.
  • John Isner and Nicolas Mahut played the longest Wimbledon match ever in 2010, taking over 11 hours stretched across three days to finish their first-round match (Isner won 4-6, 6-3, 7-6, 6-7, 70-68). The fifth set alone (eight hours) would have broken the previous match length record. They met again in the first round the very next year, and BBC coverage showed that they had become very close friends after their marathon match.
  • Stephen Colbert admitted he didn't like Jon Stewart when the latter first began hosting The Daily Show in 1999, but they've long-since become Heterosexual Life-Partners.
  • Boxers Micky Ward and Arturo Gatti were described as "united by all that damage they had done to each other", first bonding in the hospital after their second fight (out of three).
  • A Spanish proverb goes, "It is good to have friends, even in hell."
  • Keith Olbermann argues in this video that this happens with sports teams and the unique bond among members of sports teams is part of the reason why gay slurs are so prevalent in sport, as men are not always able to understand those feelings.
  • While The X-Files had protagonists Mulder and Scully engaging in Belligerent Sexual Tension amidst the personality conflicts, in real life, David Duchovny and Gillian Anderson were constantly on each other's nerves, not helped by grueling shoots (in Anderson's words, “I think the grind of working every single f——— day, 17 hours a day, with each other, in those circumstances, just took its toll."). That being said, once the show ended, they actually became friends.

Alternative Title(s): Fire Forged Friend, Fire Forged Friendship
