* In ''WesternAnimation/SpiderManAcrossTheSpiderVerse'', ComicBook/SpiderMan2099's AllianceOfAlternates is dedicated to preventing these [[spoiler:after he himself caused one by trying a DeadPersonImpersonation of an alternate version of himself with a happier life, destroying that universe entirely. When Miles interferes in the history of ComicBook/SpiderManIndia2004, he causes the reality to slowly start collapsing while 2099 and his allies try to undo the damage, and threatens to do it again by saying ScrewDestiny after learning his father is fated to die. Or at least that's what Miguel/Spider-Man 2099 says. He doesn't actually offer any proof to back up his claims, and the collapse of his alternate reality looks suspiciously like the way the Spot's powers work, same goes for the destruction in Spider-Man Inda's reality]].

* ''WesternAnimation/WhatIf2021'' has an episode where Comicbook/DoctorStrange loses his girlfriend Christine in a car accident, and given that repeated attempts only using his magic isn't enough to prevent that from happening, he goes through a very dark path trying to become powerful enough to be able to save her life. And the end result of undoing something that was meant to be (the accident has what made him become Sorcerer Supreme - Christine's death here, Strange injuring his hands in [[Film/DoctorStrange2016 the original story]], where she was only his {{Amicable Ex|es}}), as he realizes much too late, is the dissolution of all of reality.

* In ''VideoGame/HalfLife: Opposing Force'', if you hop into the Xen portal right after Freeman, [[NonStandardGameOver the game ends]] stating you created a time paradox.

* ''VideoGame/OuterWilds'' has two {{Non Standard Game Over}}s related to messing with the [[{{Precursors}} Nomai's]] black hole and warping technology, which reward you with "YOU DESTROYED THE FABRIC OF SPACETIME" Game Over screens, a credits sequence played with the game's theme played on the {{kazoo|s Mean Silliness}}, and of course achievements.

** An update added another method by which you can destroy reality: [[spoiler:hang around the warp core at the center of the Ash Twin Project when the current [[GroundhogDayLoop cycle]] ends, and it'll open up and suck you into another artificial black hole. You'll start the next cycle as normal, but now, hanging out inside the Ash Twin Project, is [[TemporalDuplication the you from the previous cycle]], sent backwards in time by the concurrent white hole. Fail to satisfy the time loop you’ve just complicated by entering the Ash Twin Project black hole at the end of the cycle, and reality will break the exact same way, only this time the cracks radiate out from your past self.]]

* In ''VideoGame/OuterWilds'', this can happen if one tampers too much with one of the Nomai's smaller experiments: In the High Energy Lab, you'll find a time travel experiment making use of an artificial black hole and a corresponding white hole next to it. If you divert power from the lab to the experiment, launching your scout drone will make it come out of the white hole an instant ''before'' it falls into the black hole. At that moment, the exact same drone exists in two separate places, which is all fine and dandy as long as the drone enters the black hole, satisfying its time travel through the white hole as a result. However, if you're feeling particularly bold ([[TooDumbToLive or foolish]]), [[spoiler:you can pull out either capsule generating the holes at the moment the two drones are together, ''before'' your launched drone enters the black hole. Doing this causes reality to start growing negative-colored cracks on the "white hole" drone, [[GrandfatherParadox since it shouldn't be able to exist if it never went through the black hole]]. It ends with all of reality shattering like glass and fading into nothing. [[SarcasmMode Congratulations,]] you just ended the universe on your own volition by screwing with cause and effect.]]
