Two characters are so evenly matched that the fight doesn't end until they both land the knockout blow simultaneously.
is the lethal version of this trope, and the blow does not have to come simultaneously either.

Anime And Manga
- The fight between Cleverdix and Majestix in Astérix and the Great Divide lasts so long that all the spectators leave. The next dawn finds both of them lying on the ground, and the fight is called with no winner and no loser.
- In a fierce battle in Angel of the Bat, Red Hood slashes Spoiler’s ACL in an attempt to cripple her. After a distraction by Nightwing, she manages to return the favor. Neither of them fall unconscious, but neither is able to continue fighting.
- Just barely averted in Rocky II, when Rocky gets to his feet at 9 and Apollo can't make it. A very rare but occasional Truth in Television for real life boxing and MMA type matches as well.
- In a similar ending to that of Rocky II forty years later, in comedy The Milky Way both boxers crumple to the canvas, but protagonist Burleigh manages to get up at the count of nine.
- The same is nearly true in the Blur short film A Gentleman's Duel. A Frenchman and a Britannian face off in steam-powered death mechs, each new feat (grapple, toss into building, fist-onna-chain, electric fish coil, poodle cannon) is countered by another attack until finally both mechs are pushed to the limits of their overdrive, shred each others limbs, crash together to knock the other over, and explode. Both gentlemen crawl from the wreckage and inch across the ground until they bump heads and vaguely try to start fighting again.
- Sgt. Bilko: A recreation of the episode of The Phil Silvers Show shown below occurs in a flashback explaining why Major Thorn wants revenge on Bilko.
- Kick-Ass and Red Mist in Kick-Ass. However, Kick-Ass manages to get up soon after.
- Slaves of the Mastery has a ritual fighting form in which one of the most spectacular maneuvers is to not block the opponent's strike (both participants wear cat-claw style weapons), but to anticipate the impaling, charge, and impale the opponent while simultaneously being impaled.
- Not strictly a knockout, but in the children's book Mr. Biff the Boxer, Mr. Biff and Mr. Bop suddenly "[biff] and [bop] each other out" in the first round for a simultaneous ten-count.
- Subverted in Matthew Reilly's Scarecrow. Schofield and Wexley hit each other with withering blows almost simultaneously, fall to the floor... and keep fighting!
- Gawain and Ywain do this in one medieval romance; Gawain actually does things like it in lots of places because he was the baseline of awesome, and putting your guy up against Gawain without running into Mary Sue syndrome was a generally effective move. (Lancelot wins, by the time he gets his. In this case, they fight until they fall off their horses, and then fight until their armor and weapons (though not helmets) are wrecked, and then fight until they can't get up anymore. Then one bloody mess asks the other bloody mess his name, and it turns out he's nearly killed his best friend. Crying and kissing ensues. Seriously.
- Note that apart from the kissing, this could have happened in a modern fighting anime and you wouldn't know the difference, but for the French poetry.
- Much later, in Malory's Le Morte d'Arthur, some while before Gawain and Lancelot have their climactic battle, Gawain and Arthur hear that Lancelot's killed Gawain's younger brothers who were actually on his side without noticing, and do this...synchronized swooning thing. Twice.
- While not technically a knockout, the epee match between Phule and the Red Eagles commander (whose units were tied 1-1 in this particular competition, and 1-1 in the overall competition, making this duel the absolute tiebreaker) in Phule's Company ended with both opponents striking each other simultaneously on a sudden death point, meaning they have both scored the winning point. Under tournament regulations, this is rules as a double loss, which means that Omega Company and the Red Eagles tied, 1-1-1 each.
- This occurred in a boxing match on The Phil Silvers Show due to the fact both boxers were under the impression they were supposed to take a dive. Taken to the extreme, since only one of the boxers took a punch "out of boredom". Immediately after it connected, both boxers (the guy who got hit and the guy who did the hitting) took the dive.
- A similar scenario happened in a prison boxing match in an episode of Porridge. In that instance, they had both been bribed.
- Happened at the end of the three-way phony brawl between Conan O'Brien, Stephen Colbert, and Jon Stewart back during the writer's strike.
- Happens to Francis and Lavernia in one episode of Malcolm in the Middle.
- Not uncommon in Professional Wrestling as well, especially if a title or plot point is on the line.
- In the Triple H/Shawn Michaels Last Man Standing match at Royal Rumble 2004, both men were knocked out and neither was able to make it back to his feet. This happens in about half the LMS matches.
- Happens a little in battle royals as well, including the Royal Rumble itself. The '94 event ended when Bret Hart and Lex Luger took each other over the ropes at the same time. John Cena and Batista eliminated each other in the '05 Rumble faux finish.
- Professional Wrestling can also have the Double Pin, or the even rarer double Pin/Submission, as with Kurt Angle being pinned while making The Undertaker tap out to a triangle choke.
- During the peak of their feud, The Rock and Mankind's match at St. Valentine's Day Massacre: In Your House ended this way. Needless to say, the entire match was an exchanging of No-Holds-Barred Beatdown.
- Possible in the card game Magic The Gathering (among many, many others) — both players can hit zero or less life and it's a draw. Later editions of the game partially avert this (a "loss" counts at the end of an action rather than the end of a phase, making the window for a draw that much narrower).
- Many scenarios allow it in the Yu-Gi-Oh! CCG, though, and is in fact the purpose of a tournament-specific strategy using Self-Destruct Button (a card that reduces both players life points to 0 if your opponent's life points are a good deal higher than your own); as long as at least one duel in a match is a win, all other duels in that match can result in a draw and still count as winning that match.
- In the board game Stratego, equal-ranked pieces capture each other in duels.
- Double KOs are possible in every Fighting Game, make no mistake. Mostly because, since it's technically possible in any fighting game, the designers have to program a way to deal with it if it happens. However, some games treat them differently. While the Street Fighter and The King of Fighters (and Samurai Shodown) series would count that as a win for both fighters (and would probably go into sudden death if it happened both times), the World Heroes series doesn't count it at all.
- In Street Fighter, when there are more than two double KOs in a row and no clear winner by the fourth round, both players lose.
- Some lower-quality Fighting Games arbitrarily declare the CPU the winner in a Double KO.
- This can also happen in games where it is possible to defeat your opponent by knocking them off the platform you are fighting on. In Soul Calibur, a player who falls off in the course of knocking someone else off in the process typically ends in a Draw.
- However, this only works if both characters fall at the same time. If one person falls off the edge just a few seconds after the first (with rather hilarious animations for the event), then the second person to fall is declared the winner.
- Speaking of Soul Calibur, Yoshimitsu's seppuku move seems to be tailor-made for these.
- Soul Calibur IV has an achievement/trophy for getting a Double KO: Two Cannot Exist Together.
- BlazBlue deals with this by giving each player a match point, unless said match point makes one player win the entire set. In that case, only the player who's behind gets a match point. If both players need one match point to win, the game continues into overtime instead of ending in a draw.
- In the Super Smash Bros. series, it's not uncommon for multiple players to hit each other at the same time, which may potentially result in two or more players K Oing each other. Due to the significant variability in launching speeds and blastline positioning however, it is very rare for two players who hit each other at the same time to be actually KO'd at the exact same time. Thus in a situation where both players are on their last stock and deal a K Oing blow to each other, one would usually outlive the other by a split second and be declared the winner by the game. If two or more players are actually KO'd at the same time on their last stock, the game will proceed to Sudden Death. And if two or more players are again KO'd at the same exact time in Sudden Death, instead of going to another round of Sudden Death, the game declares the player with the lower port the winner in Melee, while deciding the winner randomly in the other Smash games.
- Some moves can also be used as "Suicide moves" by the player to drag an opponent offstage with them (Kirby and Dedede's Inhale, Bowser's Flying Slam, and Ganondorf's aerial Flame Choke are the most prominent example of such moves). If done, usually the result is both players getting KO'd at the same time as they pass the bottom blast line, though due to some specific oddities with each move, it's possible for one player to live a split second longer in this situation and thus win the match in a last stock situation (such as in Brawl, Bowser can get KO'd second and thus win the match in his Flying Slam suicide, while Ganondorf can get KO'd first and thus lose in his Flame Choke suicide. This was then reversed for both characters in Smash 4, while Kirby and Dedede also now invariably get KO'd first and lose in their Inhale suicides). Due to the game's inconsistent handling of these moves, tournaments frequently run the "suicide rule", where if a match ends by a suicide move with both players on their last stock, the initiator of the suicide move is considered the winner regardless of what the game states.
- One game that didn't have any kind of Double KO handling was WWF Raw for the SNES. Because there were only two ways to win, pinfall and count out, there was no way to have a double KO in a 1v1 match. However, if you were playing a tag match where one teammate got a 3 count pin just as his partner got counted out of the ring (thus disqualifying his team), the game would dim to a dark gray and hard lock until you reset.
- Can happen in some other games, also—but of course, going down while taking the boss down counts as a loss. One famous example of this is the Egg Viper in Sonic Adventure, which specifically tries to take the player down with it. It's also possible to be KO'ed by the device that shoots the spiked ball falling off of the Zoness boss at the end of the battle in Star Fox 64, forcing a replay of the entire second half of the level.
- World of Warcraft, due to its asymmetric client-server model, has this sort of thing happen all the time, due to the order of events being processed differently by the server and each respective client. A classic example is two characters stunning each other simultaneously with instant attacks. A simpler case occurs when both opponents are capable of applying damage-over-time effects; this is an iconic feature (to the point of Memetic Mutation) of battles with Warlocks.
- Fighting a Warlock generally means that you end up killing them, going home, taking a shower, making a sandwich, and dying while eating it.
- The particularly thorough fan-made Kinnikuman game Muscle Fight has a number of moves that will drain your health, possibly all the way down to nil. However, provided the opponent is beaten with said move, it counts as a win. Thankfully, said moves are treated as last resorts that require *very* little health, sometimes as little as 1/16th, and victory is usually assured if one of these connects.
- Double (more like Mass-mutual) KOs are all too common in Bomberman multiplayer, due to the hectic pace of battle.
- Next-to-last boss in Purple literally mirrors your characters movement, except that his frisbee disappears earlier. The strategy for easy defeat is to bring Homer Frisbee to the battle.
- Due to a change in the combo and hit detection system in Streets of Rage 3, it's possible for you to take out an enemy's remaining life and for the enemy to do the same to you at the same time. This can be quite a funny moment if you end a boss battle this way.
- Some enemies in RPGs have a Last Ditch Move they will perform upon death. Depending on the move, it is possible for the enemy (or its party) to use a move that will wipe out your party instantly as they die, resulting both sides in being knocked out. However, this counts as a Game Over for you because you didn't survive.
- Notably, one boss (Magi Master) in Final Fantasy VI would use Ultima just before dying. It was powerful enough to deal damage near the cap, and it hit everyone in your party. The only way to reliably win the fight is to case Reraise (Life3) on at least one of your party members, which revives a character automatically on death. And considering Reraise is only gained from one Esper, it required some grinding to get it.
- If you don't have Reraise or the Esper that grants it, the only other likely option is to use Rasp/Osmose to drain Magi Master's MP, making him unable to cast Ultima (also, like a few other magic-based enemies, he dies when he hits 0 MP). The fight takes an extremely long time, but seeing "Ultima...Not Enough MP" flash on the screen, followed by the boss's death, is entirely worth it.
- Having a character use the Jump command also helps since the character jumps off screen and avoids all attacks.
- Double KOs aren't too uncommon in Pokémon either — it's what attacks like Explosion are made for. In multiplayer matches, whoever initiated the attack loses. In the single-player game, the player always loses (regardless of who initiated the Desperation Attacknote ) because there would be no more Pokémon to fight with in another battle.
- In the first Super Robot Wars Original Generation, this occurs at the end of the exposition fight between Ryusei and Kyosuke, with both pilots unleashing their Mech's strongest attacks simultaneously. In the Updated Re release, the developers went out of their way to devote an entire cut-scene to the moment.
- Bulletstorm starts out with a spaceship version of this, in a combination of Taking You with Me and Ramming Always Works
- Some enemies in EarthBound, such as the Territorial Oak and the Smilin' Sphere, will explode on defeat. This almost always does "mortal damage" to the player—but due to the way the game's HP works (it drains out at a steady rate, rather than all at once), the player can usually escape the battle with only an extra chunk of HP lost. However, an ally at low health may very well die to them... and if the entire party is knocked out all at once by one of these attacks, it actually triggers a glitch.
- This is actually part of the backstory of Xenoblade. The two titans, Bionis and Mechonis, were evenly matched, and they fought for eons until, finally, they defeated each other simultaneously and both came to a standstill.
- Leela-1 and Leela-A performing a flying kick at each other in the Futurama episode "The Farnsworth Parabox".
Professor Farnsworth: Now, now. Perfectly symmetrical violence never solved anything.
- A Non Video Game example appears as a joke in Phineas and Ferb. Sort of. An episode has the Phineas, while sick in bed, playing a fighting game with his other invalid friends. Since everyone else fought against each other he has to go against himself. The result?
Announcer: (after a double knockout) Phineas WINS!
Phineas: I'm kicking my own butt!
- In the Grand Finale of The Legend of Korra, this occurs during Korra and Kuvira's climatic duel in the control room of Kuvira's Humongous Mecha. The two encounter each other in midair. Korra hits Kuvira with a point-blank airbending blast, but Kuvira has already metalbent a piece of plating in retaliation, resulting in them getting launched in opposite directions. It's not a true knockout, but the Colossus is blown in two before they can finish the fight.
