** 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.

* {{Beowulf}} and the dragon, though Beowulf had Wiglaf's assistance.

* Played straight and averted in Dragonball, with Mu Taito sealing away King Piccolo at the cost of his life. Master Roshi tried the same thing years later, but couldn't pull it off and died for nothing. HeGetsBetter, however.

** [[OrIsIt Or Was It]] all done by [[TheDragon Red Grant]]?

** Rocket launchers are especially guilty of this in ''VideoGame/QuakeIIIArena'', ''[=OpenArena=]'' and practically any game which has them, as well as mines and grenades in ''Battlefield 1942''.

* OlderThanDirt, as shown by [[http://dinosaurs.about.com/od/dailylifeofadinosaur/a/protoveloc.htm this famous fossil]]. May not quite be an example, as scientists think the combatants were actually killed by a sandstorm, but close.

* Happens in ''IdentityCrisis'' with Jack Drake and Captain Boomerang. Boomerang [[BlackestNight would]] [[BackFromTheDead return]].

[[AC:{{Film}}]]

* At the end of ''[[ThreeHundred 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.

[[AC:{{Literature}}]]

* In the ''IronDruidChronicles'' Thor manages to smash Leif's head in with his hammer but not before Leif cut him with a magical sword that kills anyone it wounds.

[[AC:LiveActionTV]]

* One episode of {{Psych}} has 2 spouses murder each other, with the first poisoning the 2nd before they were killed, and the 2nd taking a more direct approach. [[{{InspectorLestrade}} Lassiter]] is not amused that Shawn called him when there was no one alive to arrest.

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

*** And Engineer update added the Southern Hospitality, which can cause enemies to bleed out several seconds after being hit, giving them the opportunity to kill you and die themselves shortly afterward.
*** Can happen to classes with splash damage weapons. If you're playing as Soldier, are badly wounded and fire on your attacker point blank, you can expect a shower of both your chunks. Can also happen with Demomen, and Engineers if they're foolish enough to stand between an enemy and their own turret.

*** The Needler is also good at causing these because of the delay between impact and damage.

* Carrie and Margaret in ''{{Carrie}}''. Margaret stabs Carrie and Carrie strikes back, telekinetically giving her mother cardiac arrest. Carrie survives after this exchange long enough to cause [[TheLibby Chris Hargensen]] and [[JerkJock Billy Nolan]] to have a fatal car crash before the combination of shock, blood loss from the knife wound, and overstraining her body finishes her.

* After making a HeelFaceTurn, Gamma in Sonic Adventure decides that he has to "save" the rest of the E-100 Series (That is to say, destroy them, saving the little animals inside). When he defeats the last one, his brother Beta, Beta gives him one last dying attack, that causes the both of them to be destroyed.

* In ''BabylonFive: 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.

* While not a kill, given who the characters are, the spirit of the trope is invoked in ''FreddyVsJason''. After [[FridayThe13th Jason]] runs [[NightmareOnElmStreet Freddy]] through with his own severed arm, Freddy sneers and sinks Jason's machete into his body.

* In the anime version of ''Sailor Moon'', the Sailor Senshi trick Cyprine and Ptilol of the Witches 5 into doing this to each other.

* Somewhat averted at the end of ''{{Fearless}}'', where Jet Li's character could have created a near simultaneous death of he and his opponent by delivering a fatal blow, but instead only made the motions without delivering lethal force behind the strike.

* NorseMythology has this happening at Ragnarok with Loki and Heimdall, Jormungand and Thor, and Garm and Tyr.
** And Odin and Fenris...pretty much all the Norse gods bow out this way.
