Fighting Your Friend
"Have you been keeping well? Thank you for Mt. Coronet. I'm truly grateful. [...] The power you learned... I can feel it emanating from you. But that's enough talk. Let's get on with why you're here. As the Pokémon League Champion, I accept your challenge! There won't be any letup from me!"
A Boss Battle
in which you fight against a character who's explicitly on your side (otherwise it's Civil Warcraft
or Let's You and Him Fight
). Occasionally this is the Warmup Boss
in which your ally decides to test your skills before you start your real mission. It can also be a form of Heroic Sacrifice
in which the other good guy must die in order to accomplish a goal, and you have to be the one to do it. In some cases, your ally or allies are being mind-controlled
or otherwise forced to fight you. Or maybe they have done a Face-Heel Turn
and have become evil. Occasionally, especially in Fighting Games
, a character will beat up their friend to prevent them from fighting the Big Bad
. Better a few lumps than getting killed. In the end, most of the time, the real reason it happens is for the cool fight that couldn't happen otherwise
There are a few situations in which this may become a case of That One Boss
. An ally may be powered by the dark side
or has to be fought one-on-one
with either a specific character or the player character. In western RPGs about building individual character strength, no problem...you should be a Game Breaker
by this point anyways. But in a Japanese RPG that emphasizes the strength of a group working together? Having only one ally might be quite
a handicap without additional damage-dealers and tanks. Sure, in this case, the opponent may have reduced stats compared to a regular boss fight, but still almost always way more stats than they could ever actually attain while on your side
to give the player a challenge. They'll also have their entire skillsets to throw at you, occasionally even more
It may overlap with Dueling Player Characters
. Contrast Defeat Means Friendship
, in which case a villain becomes your ally because you fought it. Compare Tragic Monster
, "I Know You're in There Somewhere" Fight
. May involve a Trial by Friendly Fire
WARNING: Some of these are a little detail heavy, so SPOILER alert.
- Several Final Fantasy games use this trope:
- Doga and Unei in Final Fantasy III. Especially annoying because it's a tough Sequential Boss with no healing in the middle... even though they're ON YOUR SIDE!
- Baku in IX is the Warmup Boss variant.
- Rikku and Paine in an optional series of fights in X-2.
- Vossler in XII.
- Kain and Yang in IV as the mind control variant. Cecil's former self also has to be fought, but the hook here is not to harm him.
- Final Fantasy Tactics Advance has one battle where you have to fight Ritz in order to get to the final area of the game. She has no hard feelings against Marche, but just doesn't want him to progress any further.
- Final Fantasy Tactics A2 does it again with Adelle, who gets brainwashed by Illua after leaving your clan, and then in her possessed state, she and some monsters fight you for the grimorie while you have Luso try to talk some sense into her.
- Hell, even in Dissidia: Final Fantasy, Terra gets mind controlled into fighting one of the heroes, Cloud fights Firion to test the strength of his dream, WoL and Squall fight etc. It's not uncommon. The biggest difference between "friendly" fights and actual fights is that at the end, both heroes are still feeling alright, showing it was just a sparring matchnote .
- Fran and Balthier in Final Fantasy XII: Revenant Wings. Making this worse is that it's probably the hardest fight in the game, and that the whole thing is a stupid misunderstanding.
- The Nameless Mod features this in the WorldCorp storyline. You'll be forced to fight Slicer and Deus Diablo at some point. You also attempt to fight Phasmatis at one point, but this goes nowhere since he is effectively immortal. And if you attempt to do the Ryan ending on a WC playthrough, you'll get this with Kylie if you have rekindled your relationship with her.
- 2027 has this with Magnus at the end of the game, or not, depending on your choices.
- Done very well in Mega Man X5, with X vs. Zero. It helps that there are actually 3 possible intros to the fight, depending on who you're playing as and whether Zero "awakened" to his Superpowered Evil Side. It also helps that the ending of one of the previous games hinted that something like this would happen.
- And one game before that, Zero is forced to fight Iris. We all know how that went.
- Mega Man Star Force also does this, as in the first game Geo is forced to fight Bud, Sonia and Luna when they are tricked by the evil FM-Ians (Taurus, Lyra and Ophiuca), into getting revenge against people who wronged them (i.e. Vaughn and Veil Platz for Luna, Luna and Geo for Bud and Chrys Golds for Sonia). Then in the second game as both Bud and Luna are taken over by what Omega-Xis calls residual energy and then as Vega and Hollow trick Sonia into doing their dirty work for them. Finally in the third game as Taurus becomes corrupted by the bad guys and is forced to merge with Bud as a result of it.
- In Dragon Age: Origins, you have to fight Wynne and Leliana if you choose to despoil the Urn of Sacred Ashes while they are in your party.
- You will also have to fight Wynne if you choose to ally yourself with the templars.
- In the sequel, you can end up fighting several of your companions in the end game if you don't push their Friendship or Rivalry all the way to the extreme.
- In Atlus's Digital Devil Saga, Serph and Heat stage a fight between themselves in an attempt to make the local villain drop his guard.
- In the sequel Gale, Sera and Cielo take on Heat after he eats Serph and turns into a One-Winged Angel, to a Dark Reprise of the first game's battle theme. Subverted in that Heat's on a slightly different agenda but they're aiming for the same goal and they still consider Heat a comrade.
- The Magic Knight Rayearth SNES game featured a sequence where one of the trio had to fight the other two. This is one of the last variety, where the other guys are being mind-controlled, and in fact, you're supposed to lose; if you kill them, you get a game over. This is actually made kind of hard, or at least boring, by the fact that their AI is utterly crappy and it can take forever for them to kill you with their piss-weak attacks.
- Happens a bit in Tactics Ogre. You are guaranteed to fight Vice at least once in the game (The reasons differ, though, between him making a Face-Heel Turn or accidentally getting caught in a bad spot), Leonard often fights you, Guildus is reanimated into a death knight, and in one path, Denim's sister Kachua is so angry at you she actually stays behind in the fight against Lans Tartare!! (In other chapters, Lans tells her to run away and she obliges.)
- Tactics Ogre's Gaiden Game/Prequel, The Knight of Lodis also does this. In Path A, Orson is fought, and then Rictor is possessed, making you fight him twice. But in Path B, Rictor is only fought once and it is instead Cybil who is possessed by the Big Bad. The first Rictor battle happens regardless of path choice, as does the battle with the mermaid Aerial.
- In Yu-Gi-Oh!: Nightmare Troubadour, one section of the game pits you against a mind-controlled Joey. Winning or losing this battle results in a Game Over, so you have to use particular cards to make the game end in a draw. (This comes straight from the series, though it had a different explanation.)
- In Blue Dragon, when you encounter Marumaro for the first time, he will fight you to prevent you from interfering with his quest for medicine for his village.
- The Super Famicom game Tenchi Muyo! Game Hen has everyone's favorite Space Pirate Ryoko Hakubi as a late-game boss, following her abuction by the Big Bad halfway through the story. It's a bit of a subversion in that defeating Ryoko earns the player a Game Over; the object of the mission is to defeat the Ryoko clones (easily identifiable as recolors of the real one]] who are acting as the real one's flunkies.
- Xenogears uses this trope several times too. There's only three party members you don't fight at some point in the story.
- Advance Wars: Dual Strike features a version of this, in which potential allies pit their armies against yours in order to test your skills as a commander.
- From the first Advance Wars there's Rivals!, a secret mission you can get if you use a certain CO on specific missions. It's the same.
- Alternatively, it's just like modern military exercises. Just ignore the explosions. Heck, it could even be a computer simulation.
- In the first dungeon of Fallout 2, the main character must fight a fellow tribesman to display his worthiness. If you're smart enough, you can opt to talk your way out instead.
- Performed spectacularly in Chrono Cross. After defeating Lynx atop Fort Dragonia, Serge is body-swapped with his nemesis, but the two other members in the party never notice. At that point, your friends and Lynx in Serge's body attack you and you must defend yourself. The odd part is, you're actually given the chance to win (but what kind of heartless monster would beat his own friends into a pulp?) The outcome of the battle is the same whether you win or lose, however.
- Arguably, battling the Dragon God (the fusion of the Six Dragons) is one such battle, since Harle, the Lunar (Seventh) Dragon, merges with it irrevocably also.
- The major boss fights (against Trinity and Seraph) in Enter the Matrix are like this. The former is a sparring match between friends. In the latter case... he fights EVERYONE he meets with, apparently.
- Done pretty well in Tales of Vesperia: After the latest argument between Flynn and Yuri about what Yuri's doing, Flynn seems to finally give up, until Yuri offers him a way to make his point: a swordfight.
Yuri: You're not going to beat me in an argument. But you know what you can beat me in... (holding up his sword) This.
- The two then proceed to trash-talk each other while beating each other up. They feel better afterwards, but Flynn still loses the argument.
Flynn: I can't even win with a sword anymore.
Yuri: (teasingly) Hahaha... Loser.
- Yuri also fights a Brainwashed and Crazy Estelle in an "I Know You're in There Somewhere" Fight.
- The PS3 version adds several more opportunities to fight your friends, most notably in the team battle mode in the coliseum, the final battle of which will pit all the party members you're not using against the party members you are using.
- Also in the arena Karol (in a poor disguise and loudly claiming not to be Karol) will fight alongside his Hunting Blades guildmates if he's not in your current party. In addition if Raven isn't with you he'll appear as Captain Schwann alongside the Schwann Brigade also claiming not be Raven, although he's aware he's fooling no one.
- Happens in every Tales Series game, actually, with the exception of Tales of Eternia and Tales of Phantasia. Oftentimes it gives a nice battle?
- Unless you count fighting the Summon Spirits.
- Well, Tales of Eternia does pit you up against the Guest Star Party Member.
- Tales of the Abyss also does it the least since the only friend you fight is Asch...No one's sudden betrayals actually result in a battle.
- Tales of Rebirth goes crazy with this trope. In Tales of Rebirth, you fight every single party member, including the hero at some point, including a fistfight between Veigue and Tytree as the result of an argument about Veigue not being open with his feelings. Pretty much the only character you don't fight EVER is Mao. (Unless you count the training battle)
- Like Tales of Rebirth, Tales of Symphonia also has a little too much fun with this trope...but not to the point described above.
- The Sequel includes a possible final battle but this is one where you're supposed to lose, winning results in the Downer Ending.
- Tales of Xillia has Jude get into a scrap with Alvin after the latter goes too far in trying to snap him out of a Heroic BSOD. Additionally, the EX arena will have either Jude or Milla face off against every other member of party in three pairs, then go one on one with the character you didn't pick.
- Tales of Xillia 2 has a similar occurrence to its prequel, with your choice of Jude or Milla trying to snap Ludger out of a Heroic BSOD. The EX Tag Arena also pits you against one of your party members teamed with any of a number of different bosses for its last opponents.
- Depending on the team you choose in Touhou Imperishable Night, stage four will have you pitted against Reimu or Marisa. This is also where the difficulty level of the game spikes dramatically.
- This also happened earlier in the series, in Lotus Land Story, with Reimu and Marisa being pitted against each other in the fourth stage.
- In Ten Desires, the Stage 1 boss is Yuyuko, the Final Boss of Perfect Cherry Blossom, who here is just helping out the heroines and holding back her power to serve as a Warmup Boss.
- The third stage of Magical Battle Arena has your character finding her respective ally (Nanoha and Fate, Sarara and Kirara, Lina and Naga) only for the rules of the universe forcing them to fight to get out of their current area. The only ones that doesn't are Sakura and Kukuri, who instead invokes Defeat Means Friendship on each other for the team battle on the next stage, and Ruru and Nowel, who will go through said team battle solo.
- A variant occurs in Paper Mario: The Thousand-Year Door. One boss fight has you fighting a traditional boss but your allies are fighting alongside him.
- Also, Mario is forced to fight a possessed Princess Peach, who is now the Shadow Queen.
- A subversion of this occurs in Bayonetta where it's revealed that Jeanne, who is fought on multiple occasions, is actually the protagonist's brainwashed childhood friend.
- Happens The Legend of Zelda: Twilight Princess, wherein you must fight a possessed Princess Zelda.
- And once more in Phantom Hourglass, in which the final boss is actually your buddy Linebeck possessed by Bellum.
- In Soul Calibur II, an odd version happens in both Kilik and Xianghua's story modes. While the majority of characters fight against their enemies, these two fight because they don't want the other to go on to face Inferno and potentially be killed.
- And to a lesser extent in the same game, Seong Mi-Na defeats Yun Seong because it's "no place for kids." Presumably she's thinking of herself in terms of the Christmas Cake definition of "old".
- World of Warcraft has several. Vaelestrasz in BWL tries to beat the main boss before you get there and loses, gets partially mind controlled so he has to fight you and is weakened throughout. Considering how tough he is, it's a wonder Nefarian managed to beat him, really...
- Kalecgos, the first boss of Sunwell Plateau is a blue dragon who tried the same thing. His will is stronger or something, because you beat him by killing the monster possessing him. His ally, the third boss Felmyst was not so lucky, probably because she is some sort of undead monster by that point.
- Keristrasza! I'm noticing a pattern here. Dragons don't seem to have very much luck when they try doing our job or helping us, do they?
- Indeed, by this point about half of the dragons fought in the game are former allies. Sapphiron and Nightbane may also count, being reanimated dragons.
- The various keepers of Ulduar have all been brainwashed by the Old God Yogg-Saron, forcing you to fight them. Once defeated, they realize what's happening and offer to help you against the Old God.
- The Argent Tournament includes the player killing a lot of the Crusade's members and beating up their bosses.
- After defeating the corrupted Shado-Pan in their Monastery, the remaining defenders challenge you to battle to determine if you're prepared to fight against the Sha.
- Persona 3 FES: Aigis and Metis must defeat the rest of SEES team (except Fuuka) to get the true key.
- Baldur's Gate II. Fellow escapee and very charming thief Yoshimo has no choice but to go apeshit half way trough the game because of an unbreakable Geas oath. So yeah.) and fight with the PC. He doesn't get better, though you can deliver his heart to his church to give him some forgiveness in death.
- In The World Ends with You, you finally fight the Conductor, who takes control of Shiki using the Red Skull pin. This leads to a cutscene in which the still-possessed Shiki launches a final attack which knocks out Beat, but Neku knocks her out and slices her Red Skull pin, ending the possession.
- Melty Blood occasionally has the Back Alley Alliance of Satsuki and Sion fighting each other to prevent the other from getting killed.
- Resident Evil 5 features a boss fight where Chris and Sheva end up fighting Jill Valentine.
- Castle Crashers has this happen if you're in a multiplayer game. After rescuing a princess, the players fight to the last man to decide who gets to kiss her. Even though you can brutally cut down the other players, everyone will start the next level alive and well.
- In one of the Metal Slug games, one of the characters that you did not choose is under mind control and fights you. They can use the same weapons you can, switch them at will, and can use their melee weapons just like you can. Defeating the creature controlling the character frees the victim.
- That was Metal Slug 6. This also happens (sort of) in 3, where your character is abducted by aliens and you have to play as a different one to recover them. Along you way you fight legions of clones of the captured character.
- Happens fairly often, usually via Mind Control, in the Super Robot Wars series.
- In Super Robot Wars Original Generations, this has tallied up quite a lot. Brainwashed and Crazy victims include Kusuha (twice, by Ingram and ODE), Excellen (twice too! By Ingram, but this one got thrown into Canon Discontinuity, and Einsts, especially Alfimi) and Lamia (twice in the same game: first ODE, then Duminuss), and the rest of the ODE victims. The first game, however, pits you against Sanger (who's been fighting with you for the first few stages) in a convoluted plot of Stealth Mentor.
- In Chapter 10 of Super Robot Wars MX, Duke Fleed in UFO Robo Grendizer has to to fight Great Mazinger (piloted by Blacki) and Mazinger Z piloted by a brainwashed Kouji Kabuto. Eventually, he breaks Kouji free and defeats Great Mazinger with his help.
- Pixy is fought twice in Ace Combat Zero.
- Metal Gear has a number of these.
- In Metal Gear Solid Snake has to kill his old friend Gray Fox a second time.
- During the battle with Psycho Mantis, Snake has to fight Meryl without delivering a killing blow. If that person dies, you get a Non Standard Game Over.
- And of the Ac!d spin-off series, a fight with Venus.
- The fight with the Boss in Solid 3 may count as well, considering the whole mission and her defection were all a ruse to avoid a potential war between East and West, and she was pretty much dying for her country.
- Kingdom Hearts does this a few times. It happens twice with Riku in the first game. He is first evil and is jealous of you, then attacks, and the next time he's possessed by darkness and becomes That One Boss for several players.
- 358/2 days ends with Xion committing Suicide by Cop against Roxas.
- In Kingdom Hearts Birth By Sleep Aqua has to fight both her friends, Ventus possessed by Vanitas at the end of her chapter, and Terra possessed by Xehanort in the final chapter. Both of these characters are being directly controlled by another though and in fact will help Aqua out by resisting as best they can.
- Pops up in Kingdom Hearts 3D: Dream Drop Distance as well. The final boss of the game is Sora (Or more specifically, the Nightmare possessed suit of armor he's wearing).
- And earlier in the TRON: Legacy world, Sora is forced to fight Tron, who at this point in time is known as Rinzler. He's not technically the Tron Sora knows, who came from a copy of the original Grid, but that doesn't make it any easier on Sora.
- In the C path of Valkyrie Profile: Covenant of the Plume, every friend you sacrificed to the Plume is now an einherjar fighting on Valkyrie's side against you.
- Xenosaga stayed away from this trope until Episode III when you had to fight Shion after Kevin convinced her that siding with him was the only way to be happy.
- The final battle of Mother 3 is a great example of this, in which Lucas must fight his brother Claus, who has no idea who he actually is. However, for most of the fight, Lucas refuses to attack. By the end, Claus realizes who he is and commits suicide.
- The battles against Rundas, Ghor, and Gandrayda in Metroid Prime 3 definitely count. They all help you at various points through the game, and in the 75% ending, Samus mourns their deaths.
- In the final battle in Beyond Good & Evil, the Big Bad possesses (and clones) Jade's friends, complete with mind fuck. ("It's your fault we're suffering!")
- In the Chicago History Museum mission in Stranglehold, your ally for most of the game, Jerry Ying, betrays you and murders Billie after you take down Damon Zakarov. After you chase his ass down, the Boss Battle begins with Jerry revealing that he acted on orders from Wong, the "same guy who sent you to find her."
Jerry: We're in a hell of a business, old buddy! Nothing's ever what it seems!
- This becomes more and more the case with Pokémon League Champions through the first four "generations" of games. In Red/Blue, it's your Jerkass Rival. In Gold/Silver, you have Lance, who is on the side of Good Is Not Nice and is all "I see potential in you; now I'll try to utterly crush you to see if I'm right". In Ruby/Sapphire you have Steven who's pretty much your chum. Then in Diamond/Pearl you have Cynthia, the do-gooder Adventurer Archaeologist who wants to be your BFF, helps you save the world and wants you to know this whole battling-you thing is tremendously fun for her. Then in Black/White you have Alder, a kindly old man who walks the earth, does his best to give you a hand and has the most festive and upbeat battle theme ever. In the sequels, we have Iris, who's a cute kid and tries to help you at a couple points in the game. At this rate it won't be long before we have a game where the League Champion is a Care Bear.
- While your rivals in the first two generations of the game are both Jerkasses, May/Brendan, Wally, Barry, Cheren, Bianca and Hugh are all considerably friendlier.
- In Black 2 and White 2 the side-area Pokémon World Tournament has a unique battle type: Mix Battles. Here, the opposing battler will take one Pokémon (or two, in Triple Mix Battles) from your party and you have to switch with one of theirs. Figuring out how to take down your own party member can be a tricky business.
- Street Fighter has indulged in this trope more than a few times, most prominently in Street Fighter Alpha 3 and (Super) Street Fighter IV's Rival Battles.
- Alpha 3: Bison abducts Ryu and injects him with a portion of his Psycho Power, forcing Sagat to try and rouse him out of this as Ken and Sakura face Bison. Also, the Bushin ninja Guy tries to reach out to his best friend Cody, who has gone from the hero of Metro City to an apathetic, snarky, fight-addicted brooder, as he believes that deep down, Cody still holds some goodness in his heart.
- IV: Rose believes that Ryu is The Chosen One destined to defeat Bison, but doesn't want him to preemptively rush into danger (according to her visions, he can vanquish Bison only at a specific time). On the other end, Guy tries to prevent Rose from facing Bison herself because while she intends to eradicate (or at least stall) Bison, she has seemingly resigned herself to death and holds a far greater importance to the world than she believes (he tried this before in Alpha 3 but failed, leading Rose to eventually be possessed by Bison in the interim between Alpha 3 and II; it should be noted that he and Rose were not True Companions at this point). Cue battle (and some unintentional Ship Tease). He also confronts Cody again, mainly for the same reasons as their fight several years prior, as well as trying to convince Cody to join him in the fight against Seth and S.I.N.
- A meta example in LEGO Star Wars, as while the final boss isn't technically on your character's side, there's the fact that, in a multiplayer game, IT'S THE OTHER PLAYER.
- Agarest Senki has Valeria fighting against you in the 2nd generation when Ladius runs away from his enemies, forcing two childhood friends to fight against each other.
- In Agarest Senki 2, this happens twice in the entire game. It happens first with Sophia because Gray gets a Grand Theft Me from Chaos and she doesn't trust Chaos herself. The second one only happens if one goes to the Bad Ending and that is Eva who pulls off a Face-Heel Turn when the party minus the protagonist Gray decides to kill Chaos because Gray gets Killed Off for Real.
- In Shiren the Wanderer 3, Shiren and Asuka fight because Sensei disagreed with her. Even if you have Shiren say that Asuka's right, the fight happens anyway (and Sensei backs out of the fight, which Koppa calls him out for) So, basically, they're fighting because they had Sensei as a boss, so why not Asuka?
- The penultimate fight of Story Mode in Mortal Kombat 9 is Raiden vs. Liu Kang. It doesn't end well. It also happens a bit earlier in Kitana's chapter, where she duels her servant Jade (the latter having been sent by Shao Kahn to keep an eye on Kitana). This fight isn't nearly as emotionally heartwrenching and doesn't come at the cost of presumably destroying a long-lasting friendship.
- Like any other fighting game worth its salt, BlazBlue has cases of this. The above quote is a lampshade by Makoto, who was forced into fighting Tsubaki just to keep her from killing Noel. She even went out of her way to forge an order to withdraw just to avoid hurting Tsubaki herself, and the fighting was pretty much a last resort.
"I didn't want to have to do this... but neither of us have a choice, do we...?"
- In Chronophantasma, this happens a lot to Litchi Faye-Ling. Just because she is now in the NOL doesn't mean she discarded the friendship she built up to the likes of Taokaka and Bang Shishigami. Making matters worse, her "mission" involves striking at Bang to snatch something he treasured, and in the previous game, she has come to treat him as a very good friend. In her Arcade route win quotes, she is borderline crying after defeating Bang.
- The Dragon of Neverwinter Nights 2 will try to convince some of your party members to join him and the Big Bad against you. If you fail Influence checks with these characters, they will be swayed. Special mention goes to Qara and Sand: their rivalry means it is literally impossible to keep one without having the other turn on you.
- The granddaddy of them all: Double Dragon. In the arcade version, if two people are playing, the game ain't over after the final boss is defeated... Billy and Jimmy then have to fight each other to the death, and Marian ends up with the winner.
- Also shows up in Double Dragon Neon, though only after the credits, and without the "to the death" part.
- After defeating Apocalypse in X-Men vs. Street Fighter, the player's two characters stand there and congratulate each other. The player, however, can recover control of his/her character and attack the partner. Do so two times and a battle ensues. (The PS1 and Saturn ports lack such options, and the player has to fight their partner after Apocalypse regardless.)
- In Little Samson, just as the party all comes together, Kikira turns on Little Samson and starts the first Boss Battle because, the manual says, she "may need some coaxing by Samson to obey."
- This is a staple of the Neptunia series. A fair amount or sometimes even most of your party members will have a boss battle (or two or three) due to various circumstances. They want to test you, they want to prove that they're better than you, you have a temporary conflict of interests, there's a misunderstanding, etc.
- Happens in Guild Wars in the final mission, where the party must fight their former mentor and ally, Prince Rurik. Or rather, his decomposing zombified corpse. The Prince apparently has control of his vocal functions, but cannot control his actions due to a spell being put on him by the Big Bad of that campaign. He makes it clear that he doesn't wish to fight his comrades, but has little choice in the matter. Winning the fight causes poor Rurik to be Killed Off for Real, but ends the Lich's spell, setting him free and allowing him to finally pass on.
- Skullgirls has a couple instances:
- Filia and Painwheel.
- Samson and Leviathan, the parasite partners of Filia and Squigly, respectively. Granted they behave more like Vitriolic Best Buds, but they mostly instigate their battle because they disagree on whether the Skullheart should be pursued.
- And of course Peacock and Marie.
- The Suikoden series does this often, most notably:
- Suikoden II: The duel between Raiou and his best friend, Jowy, which gets briefly postponed when Gordo's men mortally wound Raiou's adopted sister, Nanami. In the end, if Raiou has recruited all 108 Stars of Destiny before the final battle, he can spare Jowy's life and get the best ending.
- Suikoden V: About midway through the game, the Prince has to battle his friend who's also his sister's bodyguard, Miaskis, which serves as the conclusion of the liberation of Doorat and doubles as a massive Tear Jerker.
- Art of Fighting 3: Path of the Warrior: Just before the conclusion of the game's story mode, Ryo and Robert battle each other to determine which of them will go on to face Wyler. According to canon, Robert won.
- In Strider 2, Hiryu and Hien were once best friends before Hien decided to betray the Striders and lead them to their ruin. Even though he's now sided with the Big Bad, Hien still considers Hiryu a friend and tries to convince him to abandon his mission and join his side, but Hiryu quickly turns him down and advises him to fight seriously next time they meet.
- This is expanded upon in the crossover game Namco X Capcom, where Hien tries until the very last second to convince Hiryu to abandon his mission to kill Meio, but Hiryu turns him down (and defeats him) every time. It's not until the very last chapter, and once Meio gives him the explicit order to kill him, that Hien gives up on trying.
- Namco X Capcom has several other such cases, like Wonder Momo not wanting to hurt Amazona, a fellow actress from her play which has ben Brainwashed by the enemies or King being distressed at his mentor Armor King being on the enemy side.
- In Lunar 2: Eternal Blue Complete, Ghaleon decides to abandon the Corrupt Church he's been serving and even is willing to give the party his Cool Airship... after he tests Hiro's skills on a one-on-one battle to see his worth, that is!
- In Sonic Heroes, the four teams will encounter two of the other three during their adventure. Team Sonic battles Team Rose when Amy tries to get Sonic to marry her, Team Rose battles Team Chaotix when Team Chaotix tries to get Cheese, Team Dark deals with Team Sonic when Sonic and Shadow's rivalry kicks in again and Team Chaotix and Team Dark have it out over their business with Eggman.
Non-video game examples:
Anime and Manga
- Street Fighter II: The Animated Movie: Moments before the battle with M. Bison, Ryu is forced to face his best friend and sparring partner, Ken, who'd been enslaved by Bison's Psycho Power. Rather than fight him, Ryu tries getting through to him instead, by trying to remind Ken of who he was, and their friendship - all while being relentlessly attacked. Ryu succeeds without throwing a single punch.
- Variable Geo: Much like the preceding example, Yuka ends up having to face her Childhood Friend and rival, Satomi, to free her from Miranda's control. Afterward, Yuka and Satomi turn their combined might against the cyber drive, taking Miranda with it.
- Rune Soldier Louie: Jeanie and Louie finally come to blows near the end of episode 12, when her patience with him runs out. She assumed he had come back for her because she was a woman, which struck a nerve, since it reminded her of the time her former comrade, Hector, sacrificed himself by staying behind, so she wouldn't have to die (seen at 13:23-16:57, here).
- The second Futari Wa Pretty Cure Max Heart movie has baddies Freezen and Frozen do this towards both Cure Black and Cure White when the two heroines confront them. Cure White is brainwashed first and when Cure Black refuses to fight back, they brainwash her as well. Cure White frees herself from the hold first and it takes until the two nearly plunge to their deaths that Cure Black is freed. It shakens them badly, but they use it to reaffirm their friendship once they're both free.
- In Senki Zesshou Symphogear G, this happens in the episodes 10 to 12. First, Miku is Brainwashed and Crazy and equipped with the Symphogear Shenshou Jing and attacks Chris and Tsubasa. Hibiki, who is the main motivation of Miku's power, fights her and manages to bring her back by destroying Shenshou Jing with its Anti-Magic power, while sacrificing her own Symphogear Gungnir (which by the way was about to kill Hibiki in few days, anyway). Then there are two pair of friends who are fighting each other simultaneously. Fake Defector Chris fights Tsubasa, the latter manages to destroy the Explosive Leash on Chris' neck. And Shirabe, who goes a Heel-Face Turn, fights Kirika, who nearly kills Shirabe and has also a Heel-Face Turn after their fight.
- A common thing in Yu-Gi-Oh!. Since friendship is one of the main themes, there will always be a point where the protagonist will duel a Brainwashed and Crazy friend, mostly his best friend.
- Before Yugi can duel Pegasus, he has to defeat Jonouchi in the final first.
- The famous "anchor duel" between Yugi and the Brainwashed and Crazy Jonouchi. Both of them are chained to an anchor that will drag at least one of them into the sea if the time limit is over. Between the feet of a duelist is little box that contains the key of his shackle, and reducing the Life Points of the opponent to 0 will open the box. Malik is Dangerously Genre Savvy enough to use keys which are not identical to each other, so saving attempts will become useless. Yugi successfully de-brainwashes Jonouchi be constantly reminding him of their friendship, and Jonouchi manages to get draw, so both keys can be unlocked. Jonouchi saves Yugi in the sea, while Jonouchi is saved by his little sister Shizuka.
- In the Doma arc, Yami Yugi is forced duel Yugi, whose soul was stolen by the Seal of Orichalcos.
- Also, in the Doma arc, Jonouchi duels an Face Heel Turned Mai twice. He loses his soul in the second duel, but Mai comes back to her sense.
- The final duel is between Atem and the Yugi. Yugi must defeat Atem, so the latter can leave the word of the livings or he is "trapped" in this world.
- Because brainwashing or possessing people happens a lot in Yu-Gi-Oh! GX, Judai is often forced to duel his friends and then turns them back to his side.
- Judai duels an evil Manjoume twice, once when he is brainwashed, and later when he is "zombiefied".
- Judai duels Asuka when she is brainwashed like Manjoume.
- In a twist, after Judai turns evil, he duels Jim and O'Brien to death. Jim fails to bring Judai back to his senses, but O'Brien succeeds to snaps Judai out of it since the result is a draw.
- Judai duels a possessed Johan, his second best friend, and one of the reasons why Judai turned evil before.
- In the fourth season, Judai duels Fubuki, who uses the power of Darkness, so Fubuki will retain his lost memories.

- In Yu-Gi-Oh! 5Ds, Yusei has a bad luck regarding dueling his best friends.
- Before the start of the series, Yusei was betrayed by his best friend Jack, who stole his D-Wheel and Stardust Dragon to become the King of Riding Duels in New Domino City and leaving the slums of Satellite, becoming Yusei's rival. Even so, Yusei still views him as his friend and their friendship returns after Jack loses to him in the Fortune Cup.
- Yusei learns in a hard way that his best friends Kiryu and Bruno turn out to be his enemies, the former was believed to be dead. After defeating them, they died, which incredibly saddens Yusei, who makes a Skyward Scream (Say My Name) both times. Though, Kiryu gets better. Bruno not so much.
- In Bruno's case, even though he turns out to be an enemy, he is still Yusei's friend at the same time during their duel. He tries to prepare Yusei for the final duel against Z-One and shows him a new Synchro Summoning method that Yusei should surpass. After the duel, Bruno even sacrifices his life to save Yusei from the black hole.
- If Executive Meddling did't happen, Yusei would duel his other best friend Crow, who was originally planned to be the Final Boss of the Dark Signer arc.
- Jack duels his evil-turned Love Interest Carly who like Kiryu dies after Jack's victory. Like Kiryu, she gets better.
- The final duel is between Yusei and Jack, which is a friendly duel this time. This duel gives Yusei the answer which path he wants to go in the future, and it also inspires Aki, Crow, Luca and Lua to choose their path.
- Crowbar and Daffney Unger held back when they had to fight one another for the WCW Cruiserweight Championship. The ending came when Daffney pinned him on accident!
- Jimmy Jacobs purposefully made Delirious go through this twice, first turning him against Daizee Haze and then sending MsChif against him when that turned out not work in the long run. Through mind games Jimmy also turned Ta'Darius against ACH.
- Christian said as much in WWECW when he had to defend the ECW championship against Tommy Dreamer. He found it refreshing to actually put the belt up against someone he liked.
- Niche found himself doing this at the end of the WWC Euphoria tour when he was being managed by Black Rose but his partner Lynx no longer was and she attacked Lynx, ordering Niche to join her. Niche didn't like it and eventually he and Lynx reunited as Los Fugitivos de la Calle.
- As TNA's director of wrestling operations, this became MVP's default method of dealing with wrestlers who repeatedly questioned his authority, with the threat of being fired to violators (though none of them ever were). The American Wolves Davey Richards and Eddie Edwards were first, Samoa Joe and Austin Aries also.
- Destroy The Godmodder: When Minor attempted to boost his own power, the godmodder instead manipulated the attempt into turning minor into his own minion. Minor became the biggest threat on the field up until his defeat.
- Fate/stay night, Heaven's Feel route. Shirou vs. Saber Alter. Made worse by the fact that to play Heaven's Feel, you have to have played the Fate route in which Saber is Shirou's main Love Interest.
- In the original Thundercats, Lion-O had to do this for most of the five-part "The Anointment of Lion-O" story. (Usually, the trials that the Lord of the Thundercats has to go through in this Coming of Age ritual wouldn't be administered by his friends, but seeing as they were the Last of Their Kind - that they knew about at the time - it was the only option.) Fortunately, his foe in the final and most important trial of the ritual wasn't a friend at all - it was Mumm-Ra.
