Our group of heroes are fighting against the Psycho Rangers, Evil Twins, or opponents skilled or specialized against certain techniques against them, individually, fighting to, at best, a stalemate. One of the heroes realizes it's futile fighting against their equals, so all of them switch opponents, which wins them the battle. For some reason this almost never leads to Evil Twin A being defeated by Twin B but Evil Twin B defeating Twin A, as might be expected if they're actual equal to their doubles, nor the evil ones winning due to the change. There just seems to be some rule that switching opponents automatically guarantees heroic victory, even if it doesn't make sense. A common subversion of the Plot Tailored to the Party. May be justified in that the villans use techniques that are only useful against their chosen enemy, meaning they would be useless against anyone else. Another justification that makes more sense is that the heroes don't know their own weaknesses as well as they know those of their teammates, so when they switch, their teammates know the weaknesses of their teammate and thus the Evil Twin they're up against and can thus defeat them.
- Bleach: Uryu and Chad switch opponents in their first battle in Hueco Mundo and successfully defeat them. Note that it also went in an opposite direction: initially, the speedy archer Uryu was fighting against a giant and The Big Guy Chad has been fighting against a fast shooting Arrancar. Then they switched to Mirror Match of sorts, by fighting opponents strong in the same fields as they - and completely overwhelmed them.
- Medaka Box: Medaka, Zenkichi, Kumagawa, and Ajimu were stalemated by their respective doubles. The answer? Have Medaka defeat Zenkichi's double, Zenkichi beat Kumagawa's, Kumagawa beat Ajimu, and have Ajimu defeat Medaka.
- One Piece. This happens a few times in the Enies Lobby arc. Nami gets Kumadori's key but is unable to defeat him due to his superior strength and close- to mid-range fighting, resulting in Chopper stepping in to help. Sanji is stronger than Kalifa but is unable to hit a girl, and after his defeat, Nami saves him, winning because she can counter Kalifa's bubble powers with her Clima-tact. Usopp is not strong enough to defeat Jyabura, so Sanji steps in while telling Usopp to go save Robin, defeating Jyabura with his ability to break through his specialized tekkai. Usopp manages to snipe Spandam and the guards from a distance, something no one else could do. Only Zoro and Franky end up defeating their original opponents; Kaku was a swordsman like Zoro, but Fukurou relied on speed and hand-to-hand combat, in contrast to Franky's mix of close-quarters and ranged attacks.
- In Pokémon Best Wishes, Ash's companions gets a rival of their own (Ash gets three, and Iris and Cilan have one apiece), in spite of not getting involved in some sort of major competition. Best Wishes would wind up having the largest number of multi-episode Tournament Arcs outside of the traditional regional competition (Club Battle, Clubsplosion, and Junior Cup) just so Ash, Iris and Cilan (as well as Dawn during the Junior Cup) can go up against their rivals. However, matchups in these tournaments where a protagonist faces a different rival (i.e. Iris' rival Georgia being Ash's second round opponent during the Club Battle) is actually commonplace.
- A backup story in Peter Porker, the Spectacular Spider-Ham has the Fantastic Fur meet an evil set of themselves, and they predictably go after their doppelgangers as per usual. Then the Reed Richards says that they should change opponents — so the Thing fights the Invisible Girl and Reed fights the Torch — then the Thing gets an idea... rather than fighting each other, they should fight the bad guy versions of themselves.
- Fantastic Four
- The team used this same trick decades earlier than the above Peter Porker example in one of the Silver Age Galactus stories, and in another Silver Age story involving robot doubles fighting them.
- Inverted in another early story when they were up against elemental constructs. The elementals were under strict instructions from their creator to avoid going up against their opposite numbers (Reed/Water, Sue/Air, Thing/Earth, Torch/Fire) and each ends up being defeated by its counterpart.
- This is part of the premise of the Marvel Comics crossover Acts of Vengeance. This, of course, lead to some very odd, but memorable match ups, with a variety of tones ranging from almost wacky comedy to deadly serious. Memorable stories included Daredevil vs. Ultron, the Punisher vs Doctor Doom, the Power Pack against Typhoid Mary, a group of Spidey's D-listers against the Fantastic Four, and Magneto (a Holocaust survivor) vs the Red Skull (a Nazi).
- Inverted in the very first Justice League story featuring the Crime Syndicate of America: there, the JLAers only won when each member took on their specific counterparts with a series of Overclocking Attacks.
- Sonic the Hedgehog (Archie Comics):
- This happens when Sonic and the Freedom Fighters fight their evil mirror universe doppelgangers.
- Subverted in Sonic the Hedgehog/Mega Man: Worlds Collide. Mega Man and Sonic are fighting Bass and Metal Sonic, respectively, in a stalemate. When the heroes decide to switch (thinking that their knockoffs are only programmed to beat their counterparts), they get overwhelmed instead. They decide to team up against one at a time to beat their evil doubles.
Mega Man: "Works every time", huh?
Sonic: Oh, cute, you were programmed with sarcasm.
- The Avengers
- Runaways does this during the final fight of the first volume, when the kids confront their parents. Gert's dinosaur companion Old Lace is incapable of attacking any of her family, and Karolina's family's powers don't work on each other. "Ready... set... switch!"
- The X-Men do this in The Dark Phoenix Saga. Colossus, Storm and Wolverine find themselves facing three of the Hellfire Club's Elite Mooks with power armors customized for their individual powers. Switching things up works nicely.
- In the original Young Justice comic, they're up against fake nemeses; Robin versus Joker, Superboy versus Metallo, Impulse versus Grodd. Robin works out that they need to switch. He beats Metallo, Superboy beats Grodd, and Impulse...is so annoying that he drives The Joker nuts with frustration.
- In Superman/Batman Public Enemies, Superman and Batman attempt this when Captain Marvel and Hawkman fight them. It doesn't work since Marvel and Hawkman expected it and each was prepared to fight either opponent anyway. Hawkman used a special gauntlet to hit Superman hard enough that even he would be knocked out, and Marvel exploited Batman's soft spot for kids by briefly reverting to Billy Batson. Superman and Batman beat them off-screen later.
- In Reign of Doomsday, slightly weaker clones of Doomsday were specifically designed to take out Superboy, Steel, and Hank Henshaw. After getting curb-stomped the first time, they switched and defeated them.
- In the newspaper comic strip The Amazing Spider-Man, Spider-Man is battling Kingpin while Iron Fist is battling another martial arts user, Golden Claw. The villains have studied their respective heroes moves for so long it's a stalemate until Spider-Man suggests they switch and the villains are promptly defeated.
- My Little Avengers: Pops up during the Final Battle. Except for Big Mac, who goes after Loki in order to reclaim Thor's powers, the rest of the Avengers switch which of the Dark Avengers they take on. This is due to the fact that during their previous encounter, the Dark Avengers were able to curb-stomp them.
- All Things Probable Series. In a rare villainous example, Team Probable do this against Team Possible with Rhonda fighting Kim and Grimm fighting Ron. Unfortunately for the heroes, it works.
- Comes up in the final battle of the Avengers of the Ring sequel Return of the Avengers; despite Thors personal history with Malekith, he recognises that letting the iron-wearing Tony Stark battle the Dark Elf with the weakness to iron is the better choice, while he is better-suited to battling the Balrog Malekith has unleashed.
- Time and Again. Naruto switches with Kakashi when he realizes Kakashi's lightning jutsu are needed to beat Naruto's opponent's earth-elemental armor.
- A Hollow in Equestria has Ulquiorra and Rainbow Dash each facing off against manifestations generated by Nightmare Moon to combat them; the fully Hollowfied Ichigo Kurosaki for Ulquiorra, and Mare Do Well for Rainbow Dash. Rainbow Dash decides to immediately invokes this trope.
- Denji Sentai Megaranger/Power Rangers in Space does this with the Nejirangers / the original Psycho Rangers.
- Each Psycho Ranger has absorbed the fighting knowledge of his/her opposing Power Ranger, and is thus able to properly defend and retaliate. At first, the Power Rangers do the normal "switch opponents" variant, but since the rangers are Color-Coded for Your Convenience, the Psychos just find their Rangers again and switch back. Then the Power Rangers go in all dressed like the Blue Ranger. And for good measure, they get Zhane to come in dressed as a Silver Psycho Ranger. This works due to a), the Psychos not being able to work with one another naturally, and b), the Psychos not expecting a Sixth Ranger.
- After that, the three surviving Psychos memorize each Ranger's voice so that they won't fall for that trick either. Possibly the most justified case for a show not going with this trope for more than one episode.
- Seijuu Sentai Gingaman/Power Rangers Lost Galaxy. Copis/Chameliac, a Monster of the Week that is able to copy and counter the rangers' fighting style gets outsmarted when the rangers switch fighting styles with each other, confusing the monster. Then, in the Megazord fight, he copies the Megazords' powers as well. When the Stratoforce Megazord shows up, he copies it...only for it pull out the Centaurus Megazord's gun and shoot him.
- Not "opponents" in the traditional sense, but one episode of The Magicians (2016) has the title characters given a test where they each have to perform a different task using a tool that's obviously unsuitable for said task. It takes them a while to figure out that they're meant to swap tasks with each other, as each person has a tool that's useful for another person's task.
- This is how the Toa Mata defeated their shadow counterparts in Tales of the Masks. The encyclopedia Ret-Conned it, however — in the new version, the Toa understand that the Shadow Toa were actually their inner evil, and reabsorb them by accepting it.
- Each year there were also frequently sets of enemies who were similarly color coded, such as the Bohrok, the Rahkshi, the Vahki and so on. However the Toa didn't generally express any particular desire to specifically go after their same color.
- Champions supplement Red Doom. One of the Supreme Soviets' standard combat maneuvers was "Soccer Ball", in which the team members switched opponents until they found one that was vulnerable to their attacks.
- The Order of the Stick
- Subverted. When the Linear Guild is failing to make progress against the Order, Nale suggests to Thog that they trade opponents. This actually makes things worse, as Elan's normally useless bardic magic is effective against Thog, and Roy has been holding back a strong urge to beat the tar out of Nale's twin brother Elan for quite some time.
- The Linear Guild strikes again much later. With Roy getting the tar kicked out of him by Thog, Elan fleeing Nale, and V unable to get through Zz'dtri's magical defences, V then realises that Zz'dtri's achilles heel is best countered by someone else and invokes this trope - by using the Guild's own archer specialist, to boot.
- Brawl in the Family has Bowser and Ganondorf agreeing to take on the other's rival; Bowser under the assumption that his thick shell would protect him from Link's arrows, and Ganondorf feeling confident that his magic could easily dispatch a middle-aged plumber. It works, but, when they decide that they both want to be top dog, they release their respective prisoners to attack the other, allowing Mario and Link to defeat them once again.
- "Ayla and the Great Shoulder Angel Conspiracy" in the Whateley Universe: when fighting New Olympians best suited to combatting them (even Person of Mass Destruction Tennyo), Team Kimba manages to trade opponents one by one until they defeat enough opponents that they can double-team the last couple.
- Happens in Xiaolin Showdown, when a Sheng Gong Wu creates physical manifestations of each warrior's worst fear. Defied later on the episode when the duel of the day specified they must fight their respective fear.
- In Justice League Unlimited, when Luthor-Brainiac merged being pits the League against their own Evil Twins, The Flash, Batman, and Martian Manhunter are able to defeat their doubles on their own, while the rest eventually switch opponents. Leads to an amusing exchange between Green Lantern and Hawkgirl, who both comment that the other one enjoys whacking their opponent a little too much.
Green Lantern: Just letting off some steam. She broke my heart, you know.
Hawkgirl: (knocks Lord!GL's head clean off) Likewise, I'm sure.
- Teen Titans: Cyborg, Beast Boy, and Starfire fight against their Evil Knockoffs, switching in the end to defeat them (Starfire to Evil Cyborg, Beast Boy to Evil Starfire, and Cyborg to Evil Beast Boy).
Cyborg: Told you I could kick your butt.
- In the Fox series, the X-Men once fought their evenly-matched counterparts in X-Factor until Professor X suggested they switch.
- One episode of of the 2003 Teenage Mutant Ninja Turtles had Baxter Stockman create a Turtle Robot that scanned each of the TMNT as they went to attack it, once scanned the robot could replicate their weapons and fighting style, which worked, until the TMNT switched weapons with each other.
- A Season 3 episode of Batman: The Brave and the Bold features the villains setting this up in order to get the upper hand against their respective Archenemy. The Joker fights Wonder Woman, Cheetah deals with Superman, leaving Lex Luthor with Batman.
- Inverted in an episode of The Powerpuff Girls where three crooks dress up as the Powerpuff Girls. When the Girls and the crooks throw down, both sides end up attacking their teammates by mistake before Blossom says they should just fight their counterparts to keep things simple. The whole episode is taken into Refuge in Audacity territory because the crooks' disguises are blatantly obvious to the viewernote and yet everyone including the real Powerpuff Girls and the crooks still confuses them for the real thing.
- The Reboot Episode "Wizards Warriors and a Word From Our Sponsors" has Bob, Dot, Enzo and Mike the TV fight off their evil doppelgangers in a fantasy game. It doesn't go well until Mike inadvertently switches opponents by bumping into Evil Dot (who runs screaming from Mike's incessant infomercials).
- This is how Spider-Man and his teammates defeat the Sinister Six for the first time in Ultimate Spider-Man. Kinda weird, considering that unlike usual examples, the Sinister Six are not The Psycho Rangers, but villains who have nothing to do with the team, and yet each one of them get Curb Stomp. Including those like Beetle, Kraven, and Electro, would could give the entire team a hard time...
- The Hercules: The Animated Series and Aladdin: The Series crossover "Hercules and the Arabian Night" had Hades and Jafar team up. They decide to take on each other's enemy. Jafar says Hercules should be easy for him because Hercules isn't very agile nor clever, and Hades thinks Aladdin is worthless because he doesn't have Super Strength. The heroes defeat them anyway. Afterwards, the villains try Plan B: Let's You and Him Fight.
- While antagonism at the level of actually fighting doesn't last long enough for them to switch, the Futurama episode where the gang travels to a parallel universe lampshades why this trope might be a good idea.
Leela-A: We're perfectly matched, so I'm pretty sure that gives me the advantage.
(The two Leelas flying jump kick at each other, knocking each other down.)
Professor-A: Now, now, perfectly symmetrical violence never solved anything.
- In the Young Justice episode "Terrors", Superboy (disguised as the villain Tommy Terror) fights Mammoth and Blockbuster, who are stronger than him, while Icicle Jr. fights Mister Freeze, who is a more skilled ice user. They win by switching.
- Subverted in the The Hollow episode "Hollow Games". When corned by the embodiment of their childhood fears, they figure that this is the solution, only to fail miserably after several minutes of fighting (and polite talking). It's only when Kai has to save Adam from being eaten that they realize this is a straight-forward Face Your Fears situation.
