* In the ''WesternAnimation/StevenUniverse'' episode "[[Recap/StevenUniverseS1E22StevenAndTheStevens Steven and the Stevens]]", Steven finds a time-travel device and decides to use to create a [[MundaneUtility band composed entirely]] [[MyFutureSelfAndMe of Stevens]]. What could go wrong? Right, yes, silly question - dozens of time-clones engage in a mass-melee of each other, until a HeroicSacrifice by the original Steven wipes them out, himself included. Then the one Steven remaining, thoroughly confused, ends up writing a [[LyricalDissonance cheery]] song about it.

* In the comic book miniseries ''ComicBook/IdentityWars'' Spider-Man, the Hulk and Deadpool are sucked into an alternate dimension where Spider-Man teams up with his alternate self (and his alternate's Uncle Ben, who is alive).

* PlayedWith in ''Fanfic/TheOuroboros''. After losing their original world, the turtles, April and Casey make room for themselves in the universe that they saved by convincing ''that'' reality's turtles and their friends that they need to go into space in order to sustain a StableTimeLoop. Eventually, the alternates realize something's up, and Casey tells his counterpart that they're willing to kill the others if need be in order to reclaim their lives... [[spoiler:...in order to lure that Casey into a trap under the pretense of working together to stop them.]]

* ''Film/{{Us}}'' has doppelgangers emerging to kill the original selves. [[spoiler:And in the case of the protagonist family, all four are responsible for the undoing of their "Tethered": the husband turns on a boat engine on his, the eldest daughter brakes a car and throws her copy which was hanging from the windshield away, the youngest son makes his walk into a fire, and the wife impales her doppelganger. [[TomatoInTheMirror Or is it the other way around...]]]]

* In the 2009 film ''[[https://en.wikipedia.org/wiki/(Double_Take_2009_film) Double Take]]'', Alfred Hitchcock meets his older self during the filming of ''Film/TheBirds'', and over an uneasy conversation they realise they will have to kill one another. Director Grimonprez said in an interview that [[spoiler:the coffee the elder Hitchcock sips turning to poison as an advert for coffee plays in the background mirrors the death of film due to TV and advertising, with the elder and younger Hitchcock taking the thematic places of film vs television]]. The idea of "if you meet your double, you should kill him" is played with throughout, and was even the film's tagline.

* ''Film/TheIsland''. Lincoln Six-Echo, like all of his compatriots, is a clone unknowingly being bred as spare parts for his original sponsor. After he escapes, meets and is betrayed by his original he tricks his pursuers into killing the original instead. Ironically then uses the original’s excuse (“people will do anything to survive”) to convince his pursuers to let him go. Although they did believe he was the original at the point.

* In ''Series/TheFlash2014'', the first thing the Atom Smashes does upon arriving to Earth 1 is kill his non-meta-human counterpart. It's not stated why he does this. Also, when Dr. Light is brought from Earth 2 by Zoom to kill the Flash of Earth 1 (Barry), she decides that her only way of escaping the evil speedster is to KillAndReplace her Earth 1 non-meta counterpart Linda Park. Luckily, she's stopped before she can succeed. Additionally, [[spoiler:Zoom does this several times to his own "time remnant". The first time, the "remnant" is pretending to be Jay Garrick, the Flash of Earth-2, and his murder is designed to force Barry to seek revenge. The second time is just to show Barry that this trick requires being crazy enough to be capable of killing yourself (and being crazy enough to allow yourself to be killed)]]. Caitlin's Earth-2 counterpart Killer Frost tries to kill her after Caitlin frees her, [[spoiler:but than [[BadGuysDoTheDirtyWork Zoom saves Caitlin and kills Frost instead]].]]

* [[spoiler:Dave Davenport]] of ''Webcomic/{{Narbonic}}'' meets quite a number of alternate selves and never likes any of them much, but, being a generally mellow person, only moves for a kill when [[spoiler:he's having a MadScientist [[FreakOut breakdown]] and Dave prime, his clone with a five years out of date set of memories and Dave's old haircut, wonders stupidly through the teleport]]. This is probably cathartic.

* ''VisualNovel/FateStayNight'': Archer is out to kill his alternative self [[spoiler:Shirou]]. He is injured in the first route and other things take priority in the third route, but the middle route greatly explores his reasons for why.
