[[caption-width-right:350:An event so vast that it can barely be contained in this space!]]

The mother of all {{Crisis Crossover}}s. Really: [[TropeMaker the original]]. Appeared as a 12-issue mini-series, lasting from April, 1985 to March, 1986.

As a child, little Marvin Wolfman wanted to do a big series where every hero in DC Comics, ever, would team up to fight a cosmic villain called "The Librarian" (hey, he was 10). Then Marvin grew up and became Marv Wolfman, the man who managed to make the ''ComicBook/TeenTitans'' successful.

By this time, thanks to years of AlternateUniverse stories, Franchise/TheDCU was teeming with different worlds. There was the main universe (Earth-1), the universe of the [[TheGoldenAgeOfComicBooks Golden Age]] heroes (Earth-2), the morality-switched MirrorUniverse (Earth-3)... ThePowersThatBe thought it was getting confusing, and turning off new readers. So, in 1985, Marv got the go-ahead to clean it all up.

So, there's a [[TheMultiverse Multiverse]], which is just the unified set of all the different universes. The Multiverse is guarded by a CosmicEntity called the Monitor, whose powers are related to positive matter. But his EvilTwin, the Anti-Monitor, who guards (naturally) the Anti-Matter Universe, has discovered that his powers can increase if he destroys positive-matter universes, and proceeds to destroy the entire Multiverse. Trying to stop him, the Monitor is pushed back and knocked into a coma. Awakening, the Monitor sees that the multiverse has been cut down to just the universes we've seen before. Panicking, he gathers a group of heroes from the Earths of the remaining universes, and sends them to hold back the Anti-Monitor's minions.

The series climaxes with (almost) ''[[LoadsAndLoadsOfCharacters all]]'' of the characters who ever got their own series, [[MyFriendsAndZoidberg plus their team-mates]], their {{Sidekick}}s, and their kitchen sink, [[CallingTheOldManOut ganging up to kick the crap out of the Anti-Monitor]]. There is (as you'd expect) an EarthShatteringKaboom...

And the heroes wake up the next morning on Earth. It's apparently Earth-1, and some of the heroes from other universes landed here. And the Multiverse no longer exists. And everyone remembers the heroes, even the ones that were from other Earths, being here all along. [[TimeyWimeyBall And the heroes remember the Multiverse, but no one else does, except for Psycho Pirate.]] It appears that it was AllJustADream - but then the Anti-Monitor tries to destroy reality one last time. So the Comicbook/{{Superman}} [[BadassGrandpa from Earth-2]] [[TookALevelInBadass takes a level in Badass]], screams "I HAVE HAD ENOUGH!" [[DidYouJustPunchOutCthulhu and punches the Anti-Monitor so hard that the Anti-Monitor]] [[YourHeadAsplode ceases to exist]]. Cue ''another'' EarthShatteringKaboom. Now ''nobody'' remembers the Multiverse, except for poor Psycho Pirate, who ended up locked in Arkham Asylum, raving about "how worlds lived, worlds died... nothing will ever be the same"... The End.

''Crisis'' is notable for being one of the first comic "events" (''ComicBook/ContestOfChampions'' actually came first, as well as ''ComicBook/SecretWars'', which was more of a merchandising promotion like DC's ''SuperPowers''), but also for promising "Everything you know will change! [[Franchise/TheDCU The DC Universe]] will never be the same!" and actually ''delivering''. Unfortunately, for every continuity problem it fixed three more sprang up in its place, leading Franchise/TheDCU to become even more convoluted and cluttered than it was before as writers scrambled to fill in the gaps left by characters and universes that no longer ever existed. Indeed, the changes wrought throughout the DC Universe by ''Crisis'' were so profound that, according to some, its publication marked the end of TheBronzeAgeOfComicBooks.

''ComicBook/CrisisOnInfiniteEarths'' was followed by a companion volume, ''The History of the DC Universe'', which attempted to lay out a new, concise narrative for Franchise/TheDCU; it's still worth a read as a snapshot of a bygone time in comics with beautiful art by George Perez.

Because of the holes in continuity it left behind, ''ComicBook/CrisisOnInfiniteEarths'' has spawned several CrisisCrossover sequels that have attempted, with varying success, to make sense of the mess. These include 1994's ''[[ComicBook/ZeroHour Zero Hour: Crisis in Time]]'', 2006's ''ComicBook/InfiniteCrisis'', 2007's ''ComicBook/FiftyTwo'', 2008's ''ComicBook/FinalCrisis'', and 2009's ''ComicBook/BlackestNight''. Much of the Creator/GeoffJohns era as head creative mind for GreenLantern also ties in directly with Crisis (specifically the Anti-Monitor). The in-universe ramifications of the Crisis were also a recurring theme of the late-'80s MindScrew series ''Comicbook/AnimalMan''. Much of its imagery and backstory was referenced in ''ComicBook/JLAAvengers''.

----
!!Tropes invented by this crossover include:

* CListFodder: Dozens of minor characters, from the Crime Syndicate to the Ten-Eyed Man, died. Also, averted by a lot of A List Fodder: [[spoiler: Supergirl, Barry Allen (Flash), the original Dick Grayson (Robin), and the original Green Arrow are all among the fallen.]]
* CrisisCrossover: Although Marvel's ''ComicBook/SecretWars'' was technically first, Crisis on Infinite Earths is really the TropeMaker.
* CosmicRetcon: If not the first official use, then the one [[strike: everyone]] no-one remembers. (Everyone but one man, locked in Arkham Asylum...)
* RedSkiesCrossover, unfortunately...
----
!!Tropes used include:

* AdvancingWallOfDoom: A big white one consuming the entire {{Multiverse}}.
* AndIMustScream: For the crime of [[spoiler: (apparently) awakening the Anti-Monitor]], Pariah has spent uncounted ''millennia'' dragged from universe to universe, forced to watch their destruction and unable to die himself. As he puts it on his first appearance, when blamed for the incoming doom:
-->"No... mine is not the hand which slays worlds. I can do nothing more than ''cry.''"
* AntiVillain: The Crime Syndicate in issue #1, spending their last moments trying to save their world before it is devoured by anti-matter.
* ApocalypseHow: Class X-5.
* AscendedFanfic: Essentially. See the top of the page.
* AStormIsComing: [[CosmicRetcon "Why the]] [[RedSkiesCrossover red skies?"]]
* TheAtoner: Pariah, for having destroyed his parallel universe by attempting to explore the origin of the universe, and believing himself to be responsible for the destruction of countless other parallel universes before the Anti-Monitor reveals he himself is responsible for the latter.
* BetweenMyLegs: cover of issue #8 (Barry Allen and a beaten-up Psycho-Pirate between the Anti-Monitor's legs)
** Half of the panels with Harbinger in them have this.
* BigBad: The Anti-Monitor is one of the biggest and baddest of all Big Bads. He eats universes, kills Kryptonians, wrestles the embodied Wrath of God, and battles scores of the most powerful heroes of eight universes, at once.
** Just so you'll know how bad it is, even ''Darkseid'' won't dare mess with him. He spends the event laying low, biding his time for whatever may happen.
* TheBlank: The Anti-Monitor briefly causes the Psycho-Pirate to lose his face in order to bring him to submission.
* ContinuityReboot: The Crisis' ending was essentially a reboot with an in-universe explanation.
** The most obvious are ''ComicBook/TheManOfSteel'', ''ComicBook/BatmanYearOne'', ''WonderWoman: Gods and Mortals'', ''The Legend of Comicbook/{{Aquaman}}'', ''ComicBook/CaptainAtom'', and ''ComicBook/{{Shazam}}: A New Beginning''/''The Power of Shazam!''. ''GreenLantern: Emerald Dawn'' came a few years later.
* ContinuitySnarl: Occurs to ComicBook/PowerGirl, The ComicBook/{{Legion Of Super-Heroes}}, and Donna Troy, after the Crisis was over. Hawkman's ContinuitySnarl came later and was only indirectly due to the Crisis - it came out of the ill-advised decision to set the ''Hawkworld'' mini-series in the present, after both the Golden and Silver Age Hawkmen were already established in Post-Crisis continuity.
* CosmicRetcon: Too many to list here. See PostCrisis.
* TheDarkAgeOfComicBooks: The {{Retcon}} at the end of this series is the official end of TheBronzeAgeOfComicBooks and the start of TheDarkAgeOfComicBooks for the DCU.
** Well, for some books. Other books (like the retooled Green Lantern series) remained more or less Bronze Age in tone for some years. Others (like the retooled Justice League) were considerably brighter in tone. A serious Dark Age treatment wouldn't set in for a few more years.
* DefrostingIceQueen: Doctor Light (Kimiyo Hoshi).
** Also a somewhat more literal and temporary example is Killer Frost, Firestorm's archenemy, who was emotionally altered by Psycho Pirate to fall in love with Firestorm so that they could actually work together. It was temporary as was intended.
* DidYouJustPunchOutCthulhu?: Supergirl nearly kills the Anti-Monitor all on her own halfway through the Crisis, he even admits it an issue later that she nearly got him.
* TheDragon: The Psycho-Pirate, though he's more of like the SycophanticServant or TheIgor to the Anti-Monitor.
* DullSurprise: ''"They've got [[CListFodder Prince Ra-Man]]."'' --ShadeTheChangingMan on witnessing Ra-Man's horrible death.
* EnemyMine: The villains of the DC universes team together with the heroes with the intent of preventing the destruction of all existence of the positive-matter universe by the Anti-Monitor. Most notable is Darkseid getting his licks on the Anti-Monitor by using Alexander Luthor, Jr. as a conduit for striking him with his omega beams.
* ExpendableAlternateUniverse: By the end of the story, all save one of the eponymous Infinite Earths are destroyed, and it just happens to ([[CosmicRetcon more or less]]) be the "real" one where most of DC's stories are set. And, therefore, the good guys are considered to have won.
* FlingALightIntoTheFuture: Alexander Luthor, Jr.'s origin.
* {{Foreshadowing}}: In the ''Who's Who'' guidebooks, it is said that if Kal-L, Earth-Two Lois Lane, Earth-Three Alexander Luthor, Jr. and Superboy-Prime ever returned to the surviving universe, it would mean its destruction...they just didn't specify ''[[ComicBook/InfiniteCrisis how]]''.
* GenericDoomsdayVillain: The Anti-Monitor has many of these qualities. No real personality, motivations or backstory, just ridiculous amounts of power in one package. Still, part of the concept is that he's so ridiculously powerful that it's difficult to so much as get his attention so there is some reasoning behind his seemingly Generic Doomsday Villain nature. [[TropesAreNotBad Thankfully he's such an epic threat you don't care.]]
* GratuitousSpanish: When Yolanda Montez was introduced as the second Wildcat during the series, she had an [[SarcasmMode endearing]] habit of letting spanish phrases slip into her internal monologue followed immediately by the english translation as though she were trying to teach spanish to any listening telepaths.
* {{Guyliner}}: Pariah looks like he has used too much guyliner on his eyes, which in his origin story appears after he accidentally destroyed his parallel universe. Probably meant to represent bags under his eyes from weariness.
* HeroicSacrifice: Memorably, ComicBook/{{Supergirl}} and Comicbook/TheFlash (Barry Allen). However, following the ''Man of Steel'' reboot, Supergirl [[{{RetGone}} did not exist]] due to the "Superman was the only Kryptonian survivor" edict. Both have since been [[DeathIsCheap brought back]], although it took 18 years for Supergirl to return and 23 for Barry, which is ''really'' impressive for a comic book death. So these stuck pretty good, considering the medium.
* LastVillainStand: The Anti-Monitor, multiple times. After his fortress and army get destroyed, he decides it's time to take on all the heroes by himself at the dawn of time. When this partially fails, he gets so angry that he essentially forgets his goal of multiversal conquest and concentrates solely on destroying Earth, slowly and painfully. And when that fails, and the heroes think him defeated, he clings to life through sheer force of will, multiple times, finally fighting a one-on-one duel in a weakened state with the original Superman.
-->"SUPERMAN...I...WILL...NOT...DIE...UNTIL...YOU......DIE...WITH...ME..."
* MadnessMantra:
-->'''Psycho Pirate:''' I'm the only one left who remembers the infinite Earths. You see, I know the truth. I remember all that happened, and I'm not going to forget. Worlds lived, worlds died. Nothing will ever be the same. But those were great days for me... I had a good friend in the good old days, really. He was the Anti-Monitor. He was going to give me a world to rule. Now he's gone, too. But that's okay with me. You see, I like to remember the past because those were better times than now. I mean, I'd rather live in the past than today, wouldn't you? I mean, nothing's ever certain anymore. Nothing's ever predictable like it used to be. These days... y-you just never know who's going to die... and who's going to live.
* MassiveMultiplayerCrossover: With one major exception, EVERY character who had their own series, ''ever''. The [[JusticeLeagueOfAmerica Justice League of America]], ComicBook/{{Legion of Super-Heroes}}, [[JusticeSocietyOfAmerica Justice Society of America]], and ComicBook/TeenTitans of course, but also DC's UsefulNotes/WorldWarII army heroes, the magic heroes, the legacy heroes, the Knights of the Round Table, ComicBook/AmbushBug. Most epitomized by one scene where the Gotham heroes go to meet in Wayne Manor... and a glitch in time drops Anthro the Caveman and his supporting cast in the parlor. Long awkward silence, then the Gotham heroes decide to decamp to the kitchen for the duration.
** The exception of course, is the fact that Hal Jordan does not appear AT ALL in the main mini-series, because, at that point, he resigned from the Green Lantern Corps, and was succeeded by John Stewart. He does contribute heavily to the plot in the main ''GreenLantern'' book, but he's nowhere to be found in the twelve issue mini-series.
*** Hal not appearing in the book was a blessing in disguise. When DC was first compiling their "death list" for characters they would kill off, Hal was on the list due to DC wanting to kill him off so they could counter claims that having John Stewart as Green Lantern was them ripping off James Rhodes as Iron Man, by killing Hal off so that no future writers could restore Hal as Green Lantern.
** Comicbook/CaptainCarrotAndHisAmazingZooCrew don't appear either; their world, Earth-C, and its sister planet Earth-C-Minus (with funny-animal counterparts to the DCU heroes), were grandfathered into Post-Crisis reality as "alternate dimensions" rather than "parallel Earths" (causing some head-scratching among readers of a genre where the two phrases were usually used interchangeably).
* MeanwhileInTheFuture: Harbinger is a time traveler. One of her duplicates travels back in time 45,000 years to retrieve Arion, someone the Monitor needs. Her thoughts when she arrives? "Where is Arion? The Monitor will be ''furious'' if I cannot find him in time."
* MessengerOfDoom: Harbinger, sent by the Monitor across the Multiverse to gather heroes and to warn them of the coming destruction of their universes. Also Pariah, though usually he comes when the universe is already in the process of being destroyed, serving more as a doomed witness.
* MilestoneCelebration: ''Crisis'' was released during DC Comics' 50th anniversary.
* MultiversalConqueror: The Anti-Monitor.
* NiceJobBreakingItHero: The Anti-Monitor declares that he will travel to the dawn of time to change history from the beginning. The heroes pool their resources to follow him there. After completing that nearly-impossible journey, they find the Anti-Monitor waiting for them. He then effortlessly drains them all of their powers, explaining that he actually used up all of ''his own'' power just getting there, and he was counting on them following him so he could use ''their'' power to change the universe instead. So if the heroes never traveled back in time, the Anti-Monitor would have been stranded powerless in the void before creation forever.
** You'd think that at the very least, somebody like Batman would have thought to say, "Wait. If he's already traveled to the dawn of time, how come we still exist?"
*** Actually addressed in story; the Spectre basically tells everyone the Anti-Monitor's scheme to wipe out existence at the dawn of time had not yet occurred, due to the Anti-Monitor waiting for the heroes to come stop him so he could destroy them at his moment of triumph.
** This was lampshaded and mocked in one of the last issues of ''ComicBook/{{Quasar}}'', a title published by DC's rival, Creator/MarvelComics. A powerful alien being known as The Geometer wants to fix what it sees as "imperfections" in the multiverse. Quasar reasons with it that the multiverse is too big to fix one problem at a time, and tells it that it should go back before the dawn of time and fix all the imperfections before they can even begin. After it goes, Quasar mentions that either it'll be powerless to change anything and be stranded there, or the Big Bang will destroy it.
* {{Novelization}}: First released in 2005, with Wolfman on writing duties, and Pérez and Alex Ross doing cover art. The story is the crisis as seen from Barry Allen's point-of-view.
* OmnicidalManiac: The Anti-Monitor, though his ultimate goal is to still rule the Anti-Matter universe after all other universes have been destroyed.
* OriginalGeneration: The Monitor and Anti-Monitor, Harbinger, Pariah, Alex Luthor, Superboy-Prime, Lady Quark, and the second Doctor Light.
* PietaPlagiarism, for issue 7. Possible TropeCodifier for comics.
* PlotRelevantAgeUp: Alexander Luthor gets one.
* PowerCreepPowerSeep: On the one end, the Penguin has an umbrella that lets him stalemate Firestorm. On the other, Maaldor the Darklord, a villain who could beat up Superman, was killed by the same blast that killed human villains Icicle and Mirror Master (and left their bodies recognizable).
* PyrrhicVictory: Uncountable googol plexes worth of people die in meaningless terror and agony, and the sole remaining universe gets {{Retcon}}ned into a DarkerAndEdgier, BloodierAndGorier universe for many years afterward. As one fansite memorably put it, "The current DC Universe is built on a foundation of corpses."
** This was the plot point in ''ComicBook/InfiniteCrisis''.
* RasputinianDeath: The Anti-Monitor takes the cake. After being weakened by his failed attempt to rewrite the Big Bang, he got attacked by the heroes in his home dimension. His powers were weakened further when a large portion of his anti-matter was drained out by Alexander Luthor and the energy of the star he was feeding on was absorbed by Dr. Light. After Negative Woman bound the Anti-Monitor with her burning radioactive body, everybody aside from the aforementioned three heroes started blasting him. Upon reaching full charge, Dr. Light unleashed all of the energy she had collected into a beam. The attack sent the Anti-Monitor flying right into a nearby planet, breaking his armor and ''burning all of his internal organs''. [[YourPrincessIsInAnotherCastle This only knocked him out for a few minutes]]. When he woke up, he absorbed a large mass of his Shadow Demons to power up, shattering the planet with his energy. With a mouth blast, he ''seemingly'' killed the Earth-1 version of Wonder Woman. Unfortunately for him, the Demons, which had been poisoned by the magicians, began fighting against him. While he was suffering from the effects, Kal-L chucked ''a moon'' at the Anti-Monitor, which worked. Superboy-Prime showed up to help, but was blasted away. Seeing that his friend wasn't killed instantly by the attack, Kal-L took it as a sign that the Anti-Monitor was weakening and smashed him with two continent-sized asteroids before picking up a third equally large one and ramming him with it. This attack buried the Anti-Monitor alive on another planet and actually ''stopped the monster's heart'', but only managed to take him down for a few seconds. He suddenly burst through the rocks, out of his armor and in his energy form, and started crushing both Kal-L and Superboy-Prime with his hands. [[VillainousRescue Darkseid saved the two]] by channeling a beam through Alexander Luthor and knocking the Anti-Monitor into the star that Dr. Light had drained power from. That didn't even do the job, as [[TakingYouWithMe the Anti-Monitor rushed out of the star in the form of a screaming fireball]], [[TheDeterminator still determined to kill Kal-L]]. Unfortunately for him, his essence was shattered by one final punch from the man he was trying to murder. Immediately afterwards, the pieces of his essence fell into the star, [[EarthShatteringKaboom making it implode]]. The explosion utterly obliterated the Anti-Monitor. Of course, he returned later on.
* TheRealHeroes: Supergirl uses this to comfort Batgirl.
-->'''Supergirl''': Barbara, there are ''thousands'' of people out there -- without powers like mine... the police, the firemen, the soldiers -- they're all ordinary people trying to keep this world from falling apart before its time.
* RetGone: Happens to almost ''the entirety of existence!''
* ResetButton: This series was one for the entire DCU.
* RippleEffectProofMemory: More like "Ripple Effect Resistant Memory", after all the various Earths merged into one coherent history, all the superheroes who survived the transformation wake up the next day with their memories of their various Earths intact and have to read newspapers and history books to learn about the changes that occurred. Their previous memories faded in a few months, replaced with ones where they lived in the shared universe all their lives and the Crisis was replaced with memories of fighting in a battle against the Anti-Monitor in 1985.
* RunningTheAsylum: The later revelation that Marv Wolfman had more or less been dreaming about this since he was ''ten'' led to a lot of accusations of this (in the negative sense) being thrown around, re: The DCU being one man's plaything for his childhood fantasies. (It's worth remembering that all of the DC higher-ups at the time signed off on it, though, so any "blame" has to be shared among a number of people.)
* SacrificialPlanet: Earth-3 is destroyed in the opening pages to establish the threat, and [[SerialEscalation that's just the beginning; by the end, all but one of the infinite parallel universes has been wiped out.]]
* ShapeshiftingExcludesClothing: Franchise/TheFlash Barry Allen runs so fast that he loses himself to the Speed Force, leaving just his uniform behind. Same thing with Wally West in ''Zero Hour''.
* ShootTheShaggyDog: All of pre-Crisis continuity.
* ShoutOut: The title is a reference to DC's early multiverse stories in ''Comicbook/JusticeLeagueOfAmerica,'' which had titles like "Crisis On Earth-1!" or "Crisis On Earth-2!" etc.
* SoleSurvivor: Of the universes devoured by anti-matter: Alexander Luthor, Jr. of Earth-3, Pariah of an unnamed parallel Earth, Lady Quark of Earth-6, and Superboy Prime of Earth-Prime.
* SpacetimeEater: The Anti-Monitor, who ate an infinite amount of universes apparently.
* TheStarscream: The Psycho-Pirate ''thinks'' of pulling this on the Anti-Monitor after Supergirl's HeroicSacrifice, if only because he's afraid of what might happen to him, as he discusses to the Flash. He's only spared because the Anti-Monitor believes in PragmaticVillainy.
* TimeyWimeyBall: Try not to think too hard about how all the time-fluxes work, or you'll see plotholes so big a Mack truck can drive through them. In particular, don't give too much thought to this line by MartianManhunter: "Time must be interchanging earlier on this Earth!"
* WhamEpisode
* WritersCannotDoMath: An infinite number of universes is destroyed... one at a time.
** WordOfGod is that there was "only" 3000 universes or so.
* YouHaveOutlivedYourUsefulness: Brainiac to Alexi Luthor.
* [[YouGottaHaveBlueHair You Gotta Have Purple Hair]]: Pariah.
* WhatHappenedToTheMouse: Skeletal, Bronze-Age Brainiac leads a group of heroes to Darkseid for help, and this is his last appearance. We know that anyone who survived the Crisis remained relatively unchanged, so this Brainiac could not have become the Milton Fine Brainiac. Is this version of Brainiac still out there?
** ''History of the DC Universe'' #2 stated that this version of Brainiac was destroyed by the Omega Men during a failed attempt to conquer the Vegan system, possibly at some point after the Crisis. Then, it vaguely mentioned a new Brainiac was created on Earth two years of the original's death.
