"Somewhere in the multiverse, there is a world I call Earth Prime. Every Earth is a variation of this one, the original — and once I destroy it, all reality will follow."Omniversal-scale Annihilation, where not just our Universe, and not just The Multiverse, but the totality of The Verse/Series Franchise, containing all alternate dimensions, planes of existence, parallel universes, possible universes, timelines, alternate continuities, realities, and Multiverses get wiped out somehow. This can take on three forms, and though every form is pretty permanent, for largely theoretical reasons they actually range in "severity" a bit, thus: Omniversal FUBAR: The Physical Destruction of everything, including all universes and anything that exists in the same manner as part of a universe. Examples of this might be the entire universe getting crushed into a singularity, and for whatever reason this destabilises the larger neighbourhood of universes or parallel realities, causing them to similarly end up crushed out of existence. Alternately, something might simply travel from universe to universe and devastate them one-at-a-time until all are destroyed with no remaining loose ends. Maybe some inevitable physical process simply leads all physically real things towards a final end state of chaos or void. The "least" severe form: if some truly godlike thing was around (maybe a supernatural being, or just a Sufficiently Advanced Physical Godnote ), it could possibly Deus ex Machina everything back - perhaps by reversing entropy, or reformatting the structure of the multiverse to at least allow some manner of interesting story to take place once again. Alternatively, if absolute entropy is the fate of everything, then perhaps one day in a googolplex years, simple physical processes might eventually lead to something interesting happening purely at random. Omniversal 404: The Metaphysical Annihilation of everything. It is not merely "the end of all things", because if this happens, nothing's there to start with. All cosmic data is irretrievably lost, and no viable backup or recoverable state exists for anything in the setting. The omniverse hasn't just been rendered into some unrecognisable state - there simply isn't a state of the physical omniverse now, and something that simply isn't there can't have a history.note Examples might include the laws of physics themselves changing or being tweaked such that they do not allow the existence of things as we understand it, or perhaps it's already possible given the metaphysics of the setting for things to get so metaphysically deranged that that they cease to be real in any cognisable sense. In any case, the point is that the multiverse and everything associated with it haven't merely been destroyed - they don't exist in any meaningful state and never did. This is less fixable, and would require, essentially, the intervention of an actual god or some other thing with control over the settings' metaphysics - a physics-based cosmic backup system built into the laws of the universe wouldn't cut it, as that might be affected as well. There would be nothing to recover at any rate, but perhaps a new reality could still be created from scratch: Omniverse v.n+1, if you like. Original Negation: The Ontological Annihilation of everything. There's no coming back from this one. Even the Powers That Be or the One True God of the setting, the Omnipredicated note Ein Sof that has absolute control over everything and anything in the setting - even these things don't survive. Bluntly, all universes, every physical thing, the laws of physics themselves, whatever metaphysical realities there might be, and whoever or whatever is ultimately behind it all - all of it simply doesn't exist once this happens. Not only is it categorically impossible for anything in the setting to perdure this, but it's also modally impossible that anything about the setting could ever exist "again". This form of the trope is necessarily metafictional, as it deconstructs the fictional nature of the setting. Basically, if the story itself pronounces that everything related to its setting or described in its content is absolutely null and utterly void, ipso facto this draws your attention to the story as a story because there's nothing left to suspend disbelief in. The creator may be declaring his or her intention to never revisit the setting, or they may be taking Refuge in Extreme Audacity in order to attack the reader's trust in narrative reliability. Any of these issues can be justified or lampshaded as needed. For example, David Foster Wallace's first novel, The Broom of the System, in which the main character suffers from existential dread that she may be a character in a work of fiction, plays this by cutting off in mid-sentence on the last page. Fridge Logic / Fridge Brilliance/ Fridge-whatever shows that Fanon can potentially claim that this is occurring offscreen when an author dies suddenly before finishing the series.

Anime and Manga
- In Soul Eater Death The Kid goes mad and decides at one point that the only way to create ultimate symmetry is to destroy all of existence. Luckily for everyone, Black*Star manages to pretty much (literally) beat some sense into him. He's back to normal now. Which is good because if Kid's choice is the 'logical' extent of the Madness of Order, then presumably his ascension at the end of the series means he could now initiate this at will without outside interference. There's a reason he took the A God I Am Not option.
- Near the end of Futari wa Pretty Cure, the Dark King is purportedly destroying multiple planets in his spare time. His goal, as stated throughout the series, is the total destruction of all existence.
- Haruhi Suzumiya, The Omnipotent has the power to do this, and that's why the SOS Brigade is so desperate to keep her own powers secret from herself.
- El Hazard 2: This is the reason Kalia exists. According Yuba Yurias, once she assembles the Trigger of Destruction, she begins to wipe out all life, in all words until nothing remains. She then crosses over into the next nearest dimension and begins this process anew, and was to repeat this until all that remained was a void. Upon which, her final act would be to turn the "Trigger" on it/herself and perish.
- In The Noozles, this is threatened by the accelerated separation of the real world and Koalawallaland.
- In Dragon Ball Super, it's said by Beerus that Zen'o can pull it off as he is said to be powerful enough to destroy ALL 12 universes if he wants to in a second! It's good thing he's a Reasonable Authority Figure.
- Although this is actually downplayed, since there are multiple timelines, with even Zen'o having his own counterparts in these. Furthermore, Zen'o can only destroy the multiverse in his own native timeline (that being a Class X-5). But there was a strong possibility of a Class Z Omniversal FUBAR scenario happening if Goku didn't summon Future Zen'o in time, who then destroyed the multiverse in Future Trunks' timeline, which was at this point completely corrupted by an Eldritch Abomination form of Merged Zamasu who assimilated it into his own very being, destroying all life, and even threatening to spill into all timelines in existence by distorting the fabric of time and space, which could result in Zen'o of all timelines destroying their own respective multiverses in response. Even if that didn't happen, Merged Zamasu was still trying to white out all mortal life and would've wiped them out himself.
- In Grant Morrison's Doom Patrol, this is what will happen if the Decreator, let free by the Cult of the Unwritten Book, is able to proceed with unmaking the universe. "Nothing. Forever and ever."
- In Lucifer, the spin-off from The Sandman, all of Creation was nearly unmade when God left creation. Since His name is on everything in Heaven, Earth and everywhere else, and it holds it all together, everything started to slowly break down. It was averted when God left His job as supreme deity to his half-angel granddaughter. Chances are her universe — the third at the time — would have survived anyway, not being entangled with God's crappy handiwork.
- This is pretty much Parallax's plan in Zero Hour - he plans to completely and utterly wipe out time/space just so he can recreate everything in his own image.
- In Marvel's Secret Wars (2015), Class Z1 (Omniversal FUBAR), at least, is what things were going to, courtesy of the Beyonders destroying the Multiverse (assuming they might have gone suicidal if succeeded). But, thankfully, Doctor Doom blew them up.
- In DC's Darkseid War, either Class Z2 (Omniversal 404) or Class Z3 (Omniversal Negation) is gonna happen to reality, courtesy of the Anti-Monitor, according to the Amazonian prophecy.
- This is actually the premise of The Infinite Loops; Yggdrassil, the magical World Tree supercomputer that underlines all of reality, suffered an unexplained systems crash that rendered eighty percent of the multiverse essentially defunct and forced the Admins to initiate the titular loops. It's very heavily implied that while things are getting better, more and more problems are cropping up as they go...
- In the Magical Girl Crisis Crossover Shattered Skies, this is the purpose of Dead End's Merry-Go-Round. Using the unending combined agony of the hundreds of captive magical girls grafted to it, it's supposed to harnesses intent (i.e., the captives' constant thoughts of "Make it stop!") to cause an Original Negation... in effect, making everything stop.
Films — Live-Action
- In Dogma, if the Word of God is ever proven wrong, all of creation will cease to exist. This is Azrael's Evil Plan - he gives Loki and Bartleby a newspaper telling of a church that, in celebration of its 100th anniversary, will absolve them of their sins when they pass through the doors. This absolving would end up contradicting God's mandate that Loki and Bartleby be banished from Heaven and never return. They do come damn close.
- This is the goal of the Warlock, and he comes damned close.
- City At The End Of Time, by Greg Bear, has the end of ALL universes come about (semi?-)naturally, around about the year 100 trillion, at the hands of the strange, physics-warping Typhon. Even better, the destruction travels backwards in time and screws around with modern-day Seattle. The main cast still manage to escape the collapse of all worlds using Green Rocks! Better yet, putting all the rocks together reboots everything from the start, which it is implied they did. Eventually.
- All of Spider Robinson's time-travel stories are fueled by the premise that a genuine temporal paradox will result in the complete annihilation of space-time from beginning to end, not only destroying everything, but causing it never to have existed at all.
- In the Keys to the Kingdom series by Garth Nix, if the House is destroyed by Nothing, reality will cease to exist (including all the Secondary Realms). This does end up happening, but it gets better, since Arthur is able to recreate the Realms from the Atlas.
- In the Belgariad series by David Eddings features a the End of All things scenario: If the Child of Dark were to win the battle with the Child of Light, the universe would cease to exist. However, in the Mallorean, it changed to the Cosmic Do-Over.
- This is what Moridin wants in The Wheel of Time- he's a Death Seeker and nihilist who projects his suicidal tendencies on the universe at large and thinks it would be best to just end Eternal Recurrence by ending everything. Though the last book shows that his master, the Dark One has the power to do this but would probably never go through with it- torturing the universe for eternity is just so much more fun.
- Essentially, the Biblical Apocalypse in Archangel Protocol. Once Main/Satan is defeated, the universe will cease to exist.
- In The Book Of Joby, the bet Lucifer makes with God has this as the winning stakes: God will destroy the universe and recreate without ignoring Lucifer's advice. Not only does Lucifer lose the bet, God explains to Gabriel that Lucifer was part of the universe, so that if he immediately recreated it as it was — minus, perhaps Lucifer — the terms would be fulfilled.
- In the Hungarian novel Odakint Sötétebb ("It's Darker Outside") a Z3 is in progress, and all the weirdness in the world is caused by it. The cellofoids are attempting to save our universe by separating it from the multiverse, but ultimately fail. In the end it's softened to a "mere" Z2.
- Unsurprisingly, Doctor Who has a few examples of this extreme. It should be noted that Doctor Who has an example in every category for this trope, and that only Doctor Who ever produced examples which can even remotely qualify for above vanilla Class Z. If there's one thing these people know, it is how to kill a lot of people/planets/etc.
- In "Journey's End", Davros comes within a hair's breadth of using a device that cancels out all matter in the entire multiverse, save for himself and his group of Daleks.
- In "The End of Time", the Time Lords planned to win the Time War by creating a paradox so severe that it would destroy all creation, past, present, and future, while they became beings of pure thought.
- The TARDIS explosion from series 5 is listed under Class X-5, but comes damn close. It comes within a single planet and a few minutes of being Class Z.
- In "The Big Bang" it reaches Class Z-3 — all realities never existed. Creation never existed. Nothing ever existed. The above statements ignore Earth and the Moon, for now, but in a couple of hours they will have never existed either. The Sun was destroyed too, since the big ball of fire that rises and sets every day was the TARDIS exploding. Note it's easy to miss that it's a Z-3 and not a Z-2, since its status is only confirmed in a single, blink and you miss it line of dialogue from a Cyberman in the previous episode. "All universes will be deleted."
- The denial of a fixed point in history at the end of Series 6 creates a temporal explosion threatening to collapse and kill all of reality, spreading outward from the point that was broken.
- Glory's portal on Buffy the Vampire Slayer would have merged our dimension and all others. Considering the differences in physical laws between dimensions, this probably would have killed almost all beings in almost all of them. As it turns out, the protectors to the key of said portal were already aware of this and mitigated this threat by turning the key into a mortal girl (Buffy's sister, Dawn). As a result of the key being mortal, once said key died the portal would automatically close, reducing the possible damage done by the overlapping dimensions.
- Kamen Rider Decade: Tsukasa, AKA the eponymous Decade, is supposedly fated to destroy all the other Kamen Riders, which in turn will destroy all the Rider worlds. Much of the tension in the series is the question of whether Tsukasa is actually evil, or just kind of a dick.
- Pro Pinball: Timeshock! has the player attempt to avert an anti-time shockwave that's capable of destroying all of reality.
- In Alterans Of Gateworld, they have, on multiple occasions, wiped out the entire multiverse causing an unknown system or entity to reset everything, except the characters, multiple times.
- This is the fate of Creation if the Nobilis lose their Valde Bellum. Retroactively, no less.
- In Exalted, The Abyssal Exalted were created by the Neverborn with the express intent of throwing Creation into Oblivion, freeing the Neverborn from their fetters to existence by getting rid of existence.
- This is the presumed goal of the Wyrm in Werewolf: The Apocalypse, although some speculate that Its goal is actually to make things as horrible as possible and keep it that way forever.
- This is Rovagug's goal in Pathfinder. It's implied that Rovagug wants to die and the only way he can is by taking everyone else with him.
- This is also the explicitly stated goal of daemonkind. Daemons find every other form of life to be inherently abhorrent, and once every creature, living, undead, and ethereal, in every dimension has been slaughtered and destroyed, they will fight among themselves. When last daemon standing finishes their bloody business, they will commit suicide, finally ensuring nothing more will ever live.
- In Dungeons & Dragons this is the goal of Tharizdun, the Mad God of Destruction. He seeks to unmake reality and destroy everything, ending with himself.
- In Planescape, two factions had this goal, but neither seriously believes it can be accomplished in their lifetimes or even that of many descendants
- The Doomguard believes omniversal destruction is imminent, and they try to prevent anyone from stopping it. Some try to hurry it along.
- The Believers of the Source believe in a concept like Nirvana, where every being (mortals and gods alike) are being tested. Pass the tests, you Ascend to a Higher Plane of Existence. Once everyone passes every test, the multiverse will end.
- This is Vecna's goal in the epic module Die Vecna Die. He threatens to consume all of reality and remake it in his own evil image.
- The first Kingdom Hearts game has this, although it's not discussed often (likely due to the younger target audience). When the story starts, a seemingly endless horde of planet-devouring hellspawn is already well underway at tearing the multiverse apart at the seams. Traverse Town, a sort of base-camp for your character, is literally an interdimensional refugee camp for people who managed to survive their world's utter annihilation.
- In Bayonetta, Balder wants to instigate this in order to reunite the Trinity of Realities, which in turn, would destroy the current universe to do so.
- Featured in the Bad Ending of Demon Path (when you win the final battle, that is) in Soul Nomad & the World Eaters. Devourlord Revya consumes Gig, kills all other gods and destroys all reality. Just because it was fun.
- The Qualia in Chaos Rings does this if the heroes fail in the final battle.
- The fourth or fifth endings of Drakengard if not for the intervention of the heroes.
- Sonic the Hedgehog (2006) comes dangerously close to Solaris (the joining of Mephiles and Iblis) devouring all of time, past, present, and future and all of existence if Sonic, Shadow and Silver hadn't stopped him.
- Live A Live. You are the one who can end everything by simply choosing the Armageddon option. It disintegrates everything, in every place, in every time period, all at once (even though just destroying the Prehisoric chapter should have been enough), so you know it's horrible.
- In Final Fantasy VI, Kefka manages to succeed in a severe Class 1 destruction of the world, and when he learns to his disgust about people's hopes, love, and dreams, he decides that he'll "Destroy everything and create a monument to Non-existence."
- In Final Fantasy VIII Ultimecia plans to use a spell called time compression to compress all of space and time into a single point, which she would then absorb and become God with a capital G, or as she calls it All Existence Denied. You can even see stars being sucked into her final form as you fight it! Fortunately Squall and co. sabotage the process, leaving it half-complete and allowing them to reach Ultimecia's time period and kill her.
- In Final Fantasy IX, Kuja comes within a hairs breadth of pulling one of these off. He almost manages to destroy the crystal that holds the fabric of reality together. Luckily after he manages to beat the party to death, forcing them to fight and defeat a big blue thing who got trapped in that crystal all along and decided that since Kuja wanted to destroy everything, it was time to end the universe, he has a last minute Heel–Face Turn, resurrects the party, and dies offscreen after Zidane has found him inside the now death-throeing Iifa Tree.
- In Dissidia the Cloud of Darkness and Exdeath had a talk about the differences in their plans to destroy existence. Exdeath himself may have rather ruled over everything but the Void has other plans.
- In Final Fantasy XIII-2, Big Bad Caius Ballad seeks to destroy all of time to free his charge, Yeul, from her curse of reincarnation. Unusually for this trope, he succeeds, and the third game is about fixing everything.
- Super Mario Bros.:
- In Super Paper Mario, this is Count Bleck's true plan. He's later backstabbed and replaced by Dimentio, who settles for a Class X-5 with the intent of reconstructing it in his own image. However, after Dimentio is defeated by the heroes, he resets it back to Class Z, since if he can't remake the world with his death, he might as well destroy all of existence with him.
- In Mario + Rabbids Kingdom Battle, the Megabug attempts to cause the destruction of every realm in existence including the Mario and Rabbids universes. It's the only thing taken seriously in the game.
- In Ratchet & Clank Future: A Crack In Time, this is implied to happen if someone tries to use The Great Clock for time travel. Nearly happens, too, thanks to Azimuth.
- Shin Megami Tensei III: Nocturne. True Demon Path. All universes in the entire omniverse are obliterated with no chance of recreation by the death of God's avatar at the hands of the demonically-powered Hito-Shura. Demons and fiends are all that's left. The Final Battle between Lucifer and God is now unavoidable...
- Shin Megami Tensei IV has The White wish for this Apocalypse, since they are sick and tired of Demons and Angels constantly at war. They want to push Flynn over the Moral Event Horizon and overload the Yamato Reactor to create a black hole that'll destroy the entire universe. And it is one of the possible endings. Yes, you caused all of existence to stop.
- In Chrono Cross, the Time Devourer intends to consume every timeline, destroying everything in existence. It can only be stopped by the titular Chrono Cross, which temporarily merges the timelines and allows Serge to Ret Gone Lavos.
- In I Miss the Sunrise, according to the Black One, the Big Bad's plan (compressing the universe into a single point of energy — essentially an artificial big crunch) will cause "the end of all things". It's not entirely clear how or why, though.
- In the game Genesis, it's revealed that after too many dimensions are born, they are all destroyed at once, melting together into one. Gelyan plans to delay this by destroying all other dimensions.
- This is the ultimate 'goal' of the Old One in Demon's Souls. The Old One is literally nothingness, and it slowly annihilates entire lands and eventually the world if not stopped.
- In Tasty Planet At the end of the game you eat the fabric of time and space
- In League of Legends Thresh's legendary skin, Dark Star Thresh, cares less for everlasting torment of individuals and more of bringing about a Class-Z annihilation of all existence. To put this into perspective, he's a major threat to Aurelion Sol, Bard, and The Void. And one of his voice lines implies he's already done a Class X-4 (Universal Scale, Physical Annihilation) to other realities before he's gotten to Runeterra's.
- In LEGO Dimensions, the Big Bad Lord Vortech plans to assimilate every single dimension into one.
- In Homestuck, messing around with the fourth wall is supposed to be even worse than Class Z, according to Karkat:
CG: BUT SUFFICE TO SAY THERE ARE JUST SOME THINGS YOU DON'T WANT TO SCREW WITH.CG: THERE ARE OUTCOMES THAT ARE EVEN WORSE THAN THE COMPLETE ANNIHILATION OF EXISTENCE ITSELFCG: FORCES MORE DAMAGING TO THE INTEGRITY OF REALITY THAN THOSE CAPABLE OF TURNING IMAGINATION INTO PURE VOIDGC: THEY ARE FORCES WHICH IF HANDLED RECKLESSLY WILL NULLIFY THE BASIC ABILITY OF INTELLIGENT BEINGS IN ALL REAL AND HYPOTHETICAL PLANES OF EXISTENCE TO GIVE A SHIT.
- It's true from the author's end too.
- The ultimate objective of Lord English is the destruction of every single iteration of every single universe. Just his entrance into this region of reality required massive amounts of apocalyptic destruction, and when he did make an appearance rather than letting other people do his work for him, he destroyed an incalculable number of souls, started mass murdering the gods, and physically shattered reality. He's even killed the author.
- The threat of such an event is a major plot point in The Order of the Stick, in that breaking all of the Gates would presumably bring about the unraveling of the world, eventually.
- This is the Parliament's end goal in Awful Hospital. Let Crash explain it in greater detail:
Crash: Imagine if you could "catch" an aggressive cancer as easily as your common colds. Got that? Good. Now imagine if you could catch it just as easily from your neighbors, a pineapple, a picnic table, or the sound of a trombone. That's what we're dealing with here — or at least, that's what the Parliament's shooting for. The Alpha Malady. The Omnivirus. And the Hospital is their petri dish.
- Goblins: Psion Minmax would, ideally, like to enact a Metaphysical Annihilation. He wants to negate things, not just from existence, but from history, so that they never existed at all. His reasoning is, existence is pain, so to end all pain, he must end all existence. He can't manage it on a universal scale, but he's figured out how to manipulate the laws of physics within the Maze of Many, a self-contained dungeon that runs on an artificial Stable Time Loop. He comes damn close, but ultimately fails because the main story's version of Kin, Minmax and Forgath disrupt his calculations.
- In The Book of Stories OCT, the worst outcome of the Book's Unwriting could be classified as Class X-5 or even Z, though it's not as much destroying as it is making everything nonexistent.
- The Quiet of The Fear Mythos is an Eldritch Abomination that slowly unmakes things, sometimes just old journals and books... and sometimes entire universes. It's been hinted that this has happened to hundreds (if not thousands) of other universes throughout time and that eventually the Quiet will absorb everything. It's just happens to be doing it really slowly.
Tav Lowe: The quiet claims us all.
- The SCP Foundation has a situation known as a ZK Reality Failure which acts as this. This falls in line considering the most prominent work that features the ZK Reality Failure.
- In Sonic for Hire, Sonic travels through time so he can save his own career, but while doing so, the time machine he uses gets stolen which leads to a series of events that kills him. However, Tails, Earthworm Jim, and Eggman travel through time separately, screwing up their shapes and messing with the fabric of space and time. Sonic then transforms and the group decide to try to fix everything by repeating their adventures. However, Knuckles joins in and that causes the group to have clones, which they have to kill. However, they were too late and the universe started falling apart pixel by pixel. There's a chance that this could've caused a Class Z destruction, as it looked like all reality and time was falling apart.
- Whateley Universe: The Star Stalker was created to destroy the multiverse in the case that the invading Eldritch Abominations couldn't be stopped by any other means. Tennyo, who is now bound to the Star Stalker, is horrified already at the Lady Avenger's previous actions, but - so far - is unaware of the true nature of the entity she's turning into.
- In Transformers, this is Unicron's ultimate goal. Given that his overall method is to eat the entire multiverse one planet at a time, it's taking him quite a while, but, impressively, he's already devoured about 22.5% of known universes that way.
- This is the goal of Owlman in Justice League: Crisis on Two Earths, once he learns of the existence of the multiverse, providing the page quote. It is quite awesome, but ultimately foiled by Batman.
- Attempted by Spider-Carnage in Spider-Man: The Animated Series. After losing Uncle Ben and Aunt May, then experiencing his world's version of The Clone Saga and having to face a 50/50 chance that he's not the real Peter Parker, he's possessed by the Carnage symbiote, this alternate universe Spider-Man sets a new standard for Ax-Crazy. He attempts to, in his own words, "Destroy all reality." His plan is basic: trigger a bomb similar to the Davros example, uptop, unraveling the bonds that keep atoms together. It won't stop at destroying the Earth, or even the universe: With the help of a portal courtesy of the technology that created The Spot, the blast will be replicated across the entirety of the multiverse, ensuring that when Spider-Carnage dies all of creation dies with him.
- Done as a joke for an intro to The Simpsons, where Kang and Kodos create a wormhole that's powerful enough to even suck God into it, leaving nothing but a blank slate.
Kodos: Smooth move, space-lax! You've destroyed the totality of existence!
- Similarly, Professor Farnsworth of Futurama makes doomsday devices as a hobby, including one that "destroys everything everywhere".
- Turtles Forever takes this concept meta when the Shredder from the 2003 animated series inadvertently kicks off a Class Z. Having stumbled on The Multiverse, Shredder hypothesizes that if he can take out "Turtle Prime", that is the original universe that spawned the rest of the multiverse, he'll be unmatched and can have free reign to do as he pleases. This "Turtle Prime" turns out to be the 1984 comic book universe. While it is true that destroying the original turtles will also eliminate any TMNTs that forked off their existence, it will also destroy all of reality because if the original 1984 Turtles are erased from existence then the franchise cannot be given birth. And the Shredder doesn't even care if he'll be erased as well. Thankfully he is thwarted and Peter Laird and Kevin Eastman remain unimpeded in bringing Teenage Mutant Ninja Turtles to store shelves.
- In The Flintstones, The Great Gazoo is sent to earth of the cavemen time as punishment for creating a device that could annihilate the entire universe and quite possibly everything else.
- In The Penguins of Madagascar, Kowalski invents a time-travel gevice. It malfunctions, and starts threatening to do this. In fact Skipper points out that a large number of Kowalski's inventions threaten to destroy them all.
- According to Solipsism, your mind is the only sure thing to exist. In Metaphysical Solipsism, everything else is just a part of your reality. When you die, all of reality is destroyed with you.
- If the Eternal inflation theory is correct — and thus an infinite set of universes exists — the calculation of probabilities becomes a Mind Screw, since everything will happen an infinite number of times. A way to get rid of this problem is to assume time will end someday (note this could be just a Class X-5, since the authors state not all universes would meet this fate). Also, note that many other physicists do not share that idea, and even the author of that paper has later considered this calculations as wrong.
