History Main / MutualKill

* Optimus Prime and Megatron in ''TheTransformersTheMovie''. Prime died of his wounds, and Megatron was chucked out the airlock in a shockingly GenreBlind move by [[TheStarscream Starscream]] before he could die of his.

* 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]].

** Rocket launchers are especially guilty of this in ''Quake Arena''/''Open Arena''/any game that has them, as well as mines and grenades in ''Battlefield 1942''.

* At the end of [[HouseOfFlyingDaggers House Of Flying Daggers]], where [[ActionGirl Mei]] and her former lover [[TheMole Leo]] mutually [[SnowMeansDeath kill]] each other. [[TheHero Jin]], her new love interest, survives.

** In ''TeamFortress2'', the Pyro can set enemies on fire, which causes DPS. This means that it's possible for someone to die from the burning even [[IncendiaryExponent after they killed the pyro]]. The Pyro Update includes two achievements for killing enemies this way. The Sniper got one as well along with the relatively slow huntsman to perform this.
*** The WAR update also gave the Soldier an achievement for killing a sniper with a rocket after he kills you, [[StealthPun aptly named]] Mutually Assured Destruction.

Compare DoubleKnockout, where both combatants inflict critical but non-lethal damage on each other. Similar to, though not quite, TakingYouWithMe. This is a common, albeit far from guaranteed, result of DeliberateInjuryGambit. May follow a MexicanStandoff. If damage is fatal, but does not prevent immediate retaliation, result may be the same (this includes TimeDelayedDeath and IncendiaryExponent). Could also be from a [[{{Self-DestructiveCharge}} Self-Destructive Charge]] or PoisonedWeapons.

* 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.

** Also Nikolai. [[CrowningMomentOfAwesome It's also pretty awesome]].
* While not a kill, given who the characters are, the spirit of the trope is invoked in [[NightmareOnElmStreet Freddy]] vs [[FridayThe13th Jason]]. After running Freddy through with his own severed arm, Freddy sneers and sinks Jason's machete into his body.

* Optimus Prime and Megatron from the 80's ''{{Transformers}}'' movie. Prime died of his wounds, and Megatron was chucked out the airlock in a shockingly GenreBlind move by [[TheStarscream Starscream]] before he could die of his.

* Also Nikolai. [[CrowningMomentOfAwesome It's also pretty awesome]].

* Can occur in ''WorldOfWarcraft'' regarding Warlocks. Warlocks are able to cast many spells which cause damage over time, and remain after the caster's death. A common complaint against warlocks regarding PVP was that, in a duel to the death between you and a Warlock, you'd always die even if the warlock dies first (the fact that he might be able to ressurect himself afterwards didn't help).

** Can also ocurr in the traditional fashion, often due to lag. Also, ome boss encounters have special conditions that the group needs to look out for that can last longer than the actual fight. It's not uncommon for people to forget about it while rushing to the boss to check what he drops, and depending on what the respective effect is, they can accidentally blow up half the raid by doing so.

* Can happen if two units with the same Initiative score go toe-to-toe in ''{{Warhammer 40000}}''. One battle report ended with an Inquisitor Lord and a 13th Company Rune Priest simultaneously smashing each other flat, for example.

[[AC:WebOriginal]]
* Happens occasionally in ''SurvivalOfTheFittest'', one particularly notable example being the fight between Cassandra Roivas and Kiyoko Asakawa.
** Also related are Gail Smith vs. Sera Wingfield and Will Sigurbjornsson vs. Stephanie Evans.
*** Joined in V4 by [[spoiler: Charlotte Cave and Jaclyn Krusche]].

* In the 1939 MGM animated short ''PeaceOnEarth'', this is how the last two human beings on Earth kill each other, leaving the Earth to be populated by sentient {{Ridiculously Cute Critter}}s.
