Apocalypse How / Class Z

Go To

"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. 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 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.
  • 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 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.

    Comic Books 
  • 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.
  • 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.
  • 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.
  • 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.

    Fan Works 
  • 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: The Morning Lights, 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. Subverted when Joker says that's not what the Merry-Go-Round does, having intentionally spread misinformation about it to intimidate the troops and keep them in line. He says that what it really does is "far, far worse"... but this is Joker, so it's anyone's guess.

  • 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.

  • Essentially, the Biblical Apocalypse in Archangel Protocol. Once Main/Satan is defeated, the universe will cease to exist.
  • The Belgariad 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 Malloreon, it changed to the Cosmic Do-Over.
  • 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.
  • One of the most powerful entities in the Cthulhu Mythos is Azathoth, a being that will end the universe when he wakes up. He won't have to actually do anything, waking up will be enough to destroy the entire omniverse.
  • 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 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.
  • 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.
  • 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.

  • 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.
  • 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.
    • 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 Wedding of River Song": The denial of a fixed point in history creates a temporal explosion threatening to collapse and kill all of reality, spreading outward from the point that was broken.
  • 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.

  • Actually happens in Food for the Gods. Satan leads an army of the damned into Heaven, and starts utterly laying waste to everything in sight. God responds by going completely insane with rage and obliterating all of creation.

    Mythology and Religion 
  • In The Book Of Job, 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.

  • 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.

    Tabletop Games 
  • In the Arkham Horror game, should you play against Azathoth and he awakens, his card clearly states the universe just ends entirely. Based on the literature that features him, the rest of the omniverse would go with it.
  • 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.
  • 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 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 fate of Creation if the Nobilis lose their Valde Bellum. Retroactively, no less.
  • 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 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 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.

    Video Games 
  • 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.
  • The Qualia in Chaos Rings does this if the heroes fail in the final battle.
  • 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.
  • 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.
  • The fourth or fifth endings of Drakengard if not for the intervention of the heroes.
  • Final Fantasy:
    • 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.
  • In the game Ge Ne Sis, 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.
  • 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.
  • 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 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.
  • 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 Prehistoric chapter should have been enough), so you know it's horrible.
  • 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.
  • 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.
    • In Sonic Generations, the Time Eater (controlled by current and past versions of Dr. Eggman/Robotnik) has the ability to erase time and space. The game starts during this process of time erasure, but because of the two Sonics, it never gets very far.
  • 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.
  • 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.
  • Tasty Planet: At the end of the game you eat the fabric of time and space.

  • 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 Homestuck, messing around with the fourth wall is supposed to be even worse than Class Z, according to Karkat:
  • 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.

  • 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.
  • Futurama: Professor Farnsworth makes doomsday devices as a hobby, including one that "destroys everything everywhere".
  • In The Penguins of Madagascar, Kowalski invents a time-travel device. 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.

  • 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 Doctor Who example with Davros, above, 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.
  • 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.
  • 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 final season of Voltron: Legendary Defender, Haggar/Honerva's motive is to be together with Zarkon and Lotor by finding a reality where the two of them are alive, but doing so would instantly destroy other realities in the process. Although she managed to reach the world she desperately craved, both alternate versions of Lotor and Zarkon reject her after realizing she's their real Honerva, and in a rage decides to obliterate all other realities until the frabic of existence has been reduced to absolute nothingness.
