History Main / MutualKill

* Comicbook/{{Superman}} and Doomsday.

* In RealTimeStrategy games, it is always possible to call in [[{{BFB}} massive ordnance]] danger close, when expecting that your units won't survive the current engagement. In ''WorldInConflict'', for example, online players often decide to not withdraw the ground units before overwhelming enemy forces, summon an airstrike (which takes some time to arrive), and let the enemy pummel them to death -- only to get hit by the bombs the moment they finish off the last defender. Sometimes, players call in the airstrike too early, killing their remaining units themselves and making it a TakingYouWithMe instead.

* In ''[[BabylonFive Babylon 5]]: The Passing of the Techno-Mages'', Galen's parents kill each other. Prior to that, his mother gave a ring to his father as a gift, which was a trap that electrocuted the guy. While he was convulsing, though, he managed to hurt several fireballs at her.

* Londo and G'Kar in ''[[BabylonFive Babylon 5]]''.

* Can happen in ''{{Exalted}}'' where combat actions are determind by ticks. if two characters are due to act in the same tick both their actions happen simulanusly and damege and afect coused by the other character take afect only after that characters turn. that way both characters can kill each other at the same time.

* An infantry battle described in the [[AllThereInTheManual manual]] of the third ''WingCommander'' game over a totally worthless planet ended with the last surviving Confederation platoon overrunning the last Kilrathi position, with the survivors lasting just long enough to report their victory before dying themselves.

*** And Engineer update added the Southern Comfort, which can cause enemies to bleed out several seconds after being hit, giving them the opportunity to kill you and die themselves shortly afterward.

*** Joined in V4 by Charlotte Cave and Jaclyn Krusche.

* The ''{{Redwall}}'' series has quite a few examples of this, both hero-vs-villain and villain-vs-villain. Examples:[[spoiler: Urthstripe the Strong and Ferahgo the Assassin both died when Urthstripe leaped from the top of Salamandastron mountain, clutching Ferahgo in a death grip. A villain-vs-villain example would be between Rasconza and Sagitar, where each mortally wounded the other within seconds of each other.]]

* At the end of ''[[Three Hundred 300]]'' one of the Spartans gets stabbed with a spear. He then grabs the spear's shaft, ''pulls it further'' in order to draw the spearman closer and slashes the poor shmuck.

Please note that as a '''Death Trope''' there are '''spoilers below'''.

* Technically happened in AdventChildren: [[spoiler: when Cloud defeats [[BigBad Sephiroth]], and Kadaj and Cloud make amends before he magically dissipates into thin air, Loz and Yazoo reappear to deliver a mortal gunshot to Cloud. The three explode in a cloud of Mako energy.]]
* [[spoiler: Spike and Vicious]] from ''CowboyBebop''.
* Overlaps with MyNameIsInigoMontoya in the case with [[spoiler: Kamina]] of ''TengenToppaGurrenLagann'': Thymilf deals him mortal wounds, but he ''decides not to die'' for long enough to obliterate an army, Thymilf included (inventing a new FinishingMove on the spot), spitting out ArcWords like they were tobacco all the while. Then he basically tells his friends, "I have to go now," and dies.
* Subverted in the final battle of ''SamuraiChamploo''. [[spoiler:Jin performs a technique which guarantees this happens as a result of it, but amazingly, he actually manages to survive from the supposedly mortal wound. Even more amusingly, the only thing he does after the recovery is leave the group on friendly terms.]]
** Originally, [[spoiler:Jin was supposed to die. Then Shinichiro Watanabe chickened out.]]
* ''InuYasha'' starts out with this. It's later revealed that [[spoiler:Naraku tricked Inu Yasha and Kikyo into killing each other]].
** And even that didn't work. [[spoiler:Kikyo decided to [[SealedEvilInACan seal him]] instead.]]
* In ''{{Basilisk}}'', Kouga Gennosuke tries for one of these with Iga-no-Oboro as a final resolution of the Kouga-Iga conflict. However, Oboro refuses to fight him [[spoiler:and commits suicide instead. Gennosuke also commits suicide, so the resolution really isn't that far off from a MutualKill.]]
** The anime also opens with Kouga Danjo and Ogen of the Iga, the grandparents of the two characters above, [[spoiler: performing a MutualKill. First Danjo inflicts a fatal wound to Ogen, then Ogen backstabs him.]] FirstEpisodeSpoiler and all. [[spoiler: Danjo is, mostly, played as the badder of the two, with Ogen receiving a moment or two of pity. Danjo kills Ogen on what appears to be mere SUSPICION that she's part of the contest. Ogen then avenges herself, and has a short moment of reminiscing about their past. They were to be married, as Gennosuke and Oboro were. Danjo's clan, if not Danjo himself, ambushed the Iga fleeing from their village (which was under attack by someone else) in an attempt to wipe them out, ruining the wedding plans. Yeah, it's a really, REALLY sad anime.]]
* In the fourth arc of UminekoNoNakuKoroNi, Battler proposes a version of this to explain Kumasawa's, Genji's, and Nanjo's first arc murders. [[spoiler:Lambda refutes this during her tea party with Bern]].
* The Lancelot and Guren ([[spoiler:but neither of their pilots]]) in ''CodeGeass''.
* [[spoiler: Wolfwood and his former mentor]] in the Trigun anime. The good guy survives long enough to get to a church and decide to NOT light up one last cigarette (honoring a request made earlier by an unrealized love-interest that he stop smoking).
* In PuellaMagiMadokaMagica, [[spoiler: Kyouko sacrifices herself to MercyKill Sayaka after the later falls to TheCorruption]].

* In the ''Film/PrinceOfPersia'' movie, [[KnifeNut Seso]] can throw any blade with surgical precision. He faces off against a Hashanshin firing bolts out of a wrist-mounted automatic crossbow. Seso has one blade left, so he jumps out of the column, runs, aims and throws it, while the Hashanshin is firing bolts at him. The blade flies true and kills the bad guy. Then Seso looks down and sees bolts embedded in his chest. He manages to throw the Dagger of Time off the tower before dying. Luckily, he [[IGotBetter gets better]], along with everyone else thanks to a [[spoiler:ResetButton]].

* The probable inspiration for this was "The Pardoner's Tale" from ''TheCanterburyTales''. [[spoiler:Two guys kill one, then drink the drink he'd poisoned before being killed.]]

* In ''[[BabylonFive Babylon 5]]: The Passing of the Techno-Mages'', [[spoiler:Galen]]'s parents kill each other. Prior to that, his mother gave a ring to his father as a gift, which was a trap that electrocuted the guy. While he was convulsing, though, he managed to hurt several fireballs at her.

* [[spoiler: Londo and G'Kar]] in ''[[BabylonFive Babylon 5]]''.

* [[spoiler: Ben and Justin]] end up doing this to each other at the end of the last season of ''{{Carnivale}}'', however [[spoiler: both survive due to avataric healing powers]].

*** Joined in V4 by [[spoiler: Charlotte Cave and Jaclyn Krusche]].
** And now we can add [[spoiler: Holly Chapman and Johnny Marsh]] of the spinoff ''Evolution''. Before this, this was how [[spoiler: Cristo Ruiz and Otis Adelaide]] died.

* King Fahn and Emperor Beld at the end of ''RecordOfLodossWar''.

* In the end of ''{{300}}'' one of the spartans gets stabbed with a spear. He then grabs the spearstaff, ''pulls it further'' in order to draw the spearman closer and slashes the poor shmuck.

* Percy French's Abdul Abulbul Amir ends with both Abdul and his opponent Ivan Skavinsky Skavar fatally wounding each other.

* {{Hamlet}} and Laertes.

<<|DeathTropes|>>

* {{Beowulf}} and the dragon.

* This appears to happen in the season 1 finale of ''EarthFinaleConflict'' with Boone and Ha'Gel, who both fire energy blasts at each other. Ha'Gel is disintegrated, and Boone is heavily wounded. Subverted in that he would have survived if [[CompleteMonster Zo'or]] had not disintegrated him while in the healing tank. He [[IGotBetter gets better]] in the final season, though.
