[[caption-width-right:350:You think this is just a trope page, but it's ''bait''. You're bait for ''them.'' ''[[TheFourthWallWillNotProtectYou You!]]''[[note]] From left to right: ComicBook/{{Superman}} of [[RaceLift Earth-23]], ComicBook/MaryMarvel of [[Creator/FawcettComics Earth-5]], ComicBook/GreenLantern of [[TwoFistedTales Earth-20]], and [[ComicBook/CaptainCarrotAndHisAmazingZooCrew Captain Carrot]].[[/note]]]]
Creator/GrantMorrison's 2014-2015 limited series exploring the post-''ComicBook/{{New 52}}'' Creator/DCComics [[TheMultiverse multiverse]]. It comprises a two-issue framing story, a set of issues each taking place on a different Earth, and a guidebook to the multiverse.

The overarching story sees the rise of a threat to all reality, the demonic destroyers known as the Gentry, and the formation of the Justice League of the Multiverse in response, with the individual Earths' stories being self-contained, akin to the structure of Morrison's ''ComicBook/SevenSoldiers''.

This version of the DC multiverse can be examined [[http://www.dccomics.com/blog/2014/08/18/the-map-of-the-multiverse here]], with all Earths profiled (except for the 7 Unknown Worlds, of course) as well as other aspects of the DC cosmology. A full-size print version of the multiverse map is provided with ''Pax Americana Director's Cut #1''.

At the 2015 San Diego Comic-Con, Morrison announced ''Multiversity Too'', a line of original graphic novels set in and beyond the 52 Earths, originally planned to kick off in 2016 with ''Multiversity Too: The Flash''. As of 2020, [[ScheduleSlip nothing has come up]], and has likely been abandoned by Morrison in favor of continuing the story in their [[ComicBook/TheGreenLantern Green Lantern run]].

The story of the 52 Earths and the team formed in the aftermath of the story continued across several stories, but they received a self-titled series in 2021, ''ComicBook/JusticeLeagueIncarnate''. In 2022, a mini-series set on Earth-11 that used the Multiversity branding titled ''Multiversity: Teen Justice'' was released. A year later in 2023, another miniseries using the Multiversity branding was released titled ''ComicBook/MultiversityHarleyScrewsUpTheDCU'', where [[Characters/HarleyQuinnTheCharacter Harley Quinn]] tries to undo her mistakes after she engages in time-travel shenanigans and discovers she's accidentally [[RetGone erased all the DC superheroes from existence]].

Now has a character page.

----
!!''The Multiversity'' provides contains examples of:

* AdaptationalSexuality:
** On Earth-36, ComicBook/TheFlash and ComicBook/GreenLantern are a gay couple known as Red Racer and Flashlight.
** The Ray of Earth-10 is gay, in keeping with the theme of each of the ComicBook/{{Freedom Fighters|DCComics}} representing different groups who were persecuted by the Nazis.
* AdaptationalVillainy:
** In ''Thunderworld Adventures #1'', Magnificus Sivana is on his father's side with [[DaddysLittleVillain Junior and Georgia]], while traditionally he's [[MadDictatorsHandsomeSon a good guy]] and friend of the Marvel Family.
** In ''Pax Americana #1'', ComicBook/SargeSteel, a hero in both Franchise/TheDCU and the Creator/CharltonComics universe, is the [[TheDragon bloodthirsty second in command]] of the [[EvilChancellor evil Vice President]].
* AdaptationDyeJob:
** The ComicBook/WonderWoman of the main universe has black hair; however, several of her alternate universe counterparts are red-heads (The unnamed pirate Wonder Woman of Earth-31 and War-Woman of Earth-36), blonde (Brünhilde of Earth-10), purple-haired (Vague of Earth-41) and strawberry blonde (Walküre of Earth-7).
** The ComicBook/{{Superman}} of the main universe has black hair; however, several of his alternate universe counterparts are blond (Hyperius of Earth-8, Savior of Earth-34 and Optiman of Earth-36), green-haired (Super-Martian of Earth-32), white-haired (Supremo of Earth-35) and strawberry blond (Cyclotron of Earth-39).
** The ComicBook/{{Catwoman}} of the main universe has black hair, while her Earth-31 counterpart has purple hair.
* AdaptationExpansion: Creator/GrantMorrison is featuring an ongoing theme of presenting ComicBook/{{Batman}} counterparts on each Earth who were all inspired by something besides a bat, as a reference to [[https://imgur.com/a/MkRrg a short story by Martin Pasko]] from ''Batman'' #256. In the context of the multiverse, Scorpion (inspired by a scorpion) is on Earth-41, Stingray (inspired by a stingray) is on Earth-34, Owl (another Bruce Wayne inspired by an owl) is on Earth-35, Shooting Star (inspired by a shooting star) is on Earth-47, and Iron Knight (inspired by a suit of medieval armor to become a literal knight) is on Earth-36. Morrison seeks to pose the question of how far the character can be stretched before they're no longer Batman.
* AdaptationNameChange:
** In pre-Crisis continuity, the pastiche of ComicBook/TheAvengers was called The Champions of Angor, who in post-Crisis continuity were retconned to be called The Justifiers. In post-''ComicBook/InfiniteCrisis''[=/=]pre-''ComicBook/{{New 52}}'' continuity they were re-imagined as the Meta-Milita of Earth-8. Here they have been re-imagined again as The Retaliators of Earth-8. This has also applied to some of their individual members.
*** An {{Expy}} of ComicBook/CaptainAmerica called Americommando pre-''ComicBook/{{New 52}}'' is now American Crusader.
*** An {{Expy}} of ComicBook/{{Hawkeye}} called The Bowman pre-''ComicBook/{{New 52}}'' is now Deadeye.
*** An {{Expy}} of ComicBook/IronMan called Tin Man pre-''ComicBook/{{New 52}}'' is now Machinehead.
** Sort of InUniverse example. The heroes of Earth-8 are all rough {{exp|y}}ies of Creator/MarvelComics characters, with their adventures published throughout TheMultiverse as [[BlandNameProduct Major Comics]]. But they also have their own UltimateUniverse comics published entitled Essential Comics, whose characters are also revealed to be their actual alternate universe counterparts residing on Earth-7. The ComicBook/CaptainAmerica and [[ComicBook/TheMightyThor Thor]] expies of Major Comics are American Crusader and Wundajin, but their [[ComicBook/UltimateMarvel Essential Major Comics]] versions are called Crusader and Thunderer.
* AdaptationSpeciesChange: In pre-''ComicBook/InfiniteCrisis'' continuity both the Champions of Angor/Justifiers and the Extremists were HumanAliens from Angor: [[AllPlanetsAreEarthLike an earth-like planet]] that also had [[ContrivedCoincidence similar technology and pop-culture]]. In their re-imaginings as the heroes and villains of Earth-8 here they are normal humans from that universe's version of Earth.
* AdaptedOut: Sivana's other daughter, Beautia, is nowhere to be seen in ''Thunderworld Adventures #1''.
* AGodAmI: In ''Pax Americana #1'', Captain Adam of Earth-4 veers into this territory, but he also has plenty of humanity left to realize in horror when his actions cross the line, and opts to have himself put on heavier medication to limit himself.
* AlliterativeName: Earth-8 has a couple of examples, given that that world is based on The Franchise/MarvelUniverse this is to be expected.
** ''The Multiversity #1'':
*** Doctor David Dibble, the human alter-ego of [[ComicBook/TheIncredibleHulk The Behemoth]].
*** Frank Future of [[ComicBook/FantasticFour The Future Family]].
** [[ComicBook/CarolDanvers Major Max]], as named in ''The Multiversity Guidebook #1''.
* AllMythsAreTrue: Well, Franchise/TheDCU basically assumes this anyway, but the map of the Multiverse puts it up front, with Dream (the home of [[ComicBook/TheSandman1989 the Endless]]), Heaven, New Genesis, Skyland (the home of the various pantheons), Nightmare, Hell, Apokolips and the Underworld (also known as the PhantomZone) all co-existing in the Sphere of the Gods. On another level, many of the Earths have heroes that are fictional in each other's worlds.
* AllianceOfAlternates: In ''Thunderworld Adventures #1'' Doctor Sivana allies with alternate versions of himself to invade the Rock of Eternity and steal the power of magic for himself and conquer the multiverse. Unfortunately, Sivanas are as treacherous as they are intelligent and they fail because they were stingy with the resources they conspired to share.
* AllThereInTheManual: ''The Multiversity Guidebook #1'' contains both information on the multiverse and a ''Multiversity'' story.
* AlternateCompanyEquivalent:
** While work on the series began a while before it was released, since then, Creator/JonathanHickman's ''ComicBook/NewAvengers'' began, which deals with the collision of alternate Earths and the seemingly unstoppable death of the Multiverse.
** The characters of Earth-8 are all based off Creator/MarvelComics properties. The Retaliators (ComicBook/TheAvengers) consist of the American Crusader (ComicBook/CaptainAmerica), Machinehead (ComicBook/IronMan), Behemoth ([[ComicBook/TheIncredibleHulk the Hulk]]), Wundajin ([[ComicBook/TheMightyThor Thor]]) and Bug (ComicBook/SpiderMan), as well as {{Exp|y}}ies of ComicBook/{{Hawkeye}}, ComicBook/BlackWidow, ComicBook/TheFalcon and [[ComicBook/MsMarvel Captain Marvel]]. There's also the Future Family (the ComicBook/FantasticFour), the G-Men (the ComicBook/XMen) and Lord Havok (Doctor Doom).
** Many of the Earths featured in the Multiverse are meant to be homages to the various DC pastiches created by other companies.
* AlternateHistory: The events adds to ''ComicBook/DCTheNewFrontier''[='=]s by revealing UsefulNotes/JohnFKennedy was never assassinated in that world.
* AlternateSelf: Being what it is, features a number of these, including Earth-4's versions of the Charlton heroes, Earth-5's versions of [[ComicBook/{{Shazam}} the Marvel Family]], [[ComicBook/{{Superman}} Earth-10's Kal-L, Earth-23's Kalel]], etc. Taken to the next level in ''Thunderworld Adventures #1'', which sees [[ComicBook/{{Shazam}} Sivanas]] from across the multiverse team up.
* AlternateUniverse: [[AlternateUniverse/TheMultiversity Has its own page]].
* AlternativeCalendar: In ''Thunderworld Adventures #1'', Dr. Sivana attempts to add a new calendar day called "Sivanaday", but it only lasts eight hours.
* AlwaysABiggerFish: Hellmachine is a giant monstrosity, with what appears to be a city on its head, and is apparently the "third angel of despair". After being driven off by the heroes in ''The Multiversity #2'', it's promptly devoured by the [[EldritchAbomination hideous things dwelling inside the Bleed]].
* AnachronicOrder: How ''Pax Americana #1'' is told: one plotline follows the consequences of President Harley's assassination, while the other shows HowWeGotHere in reverse-chronological order.
* AndTheAdventureContinues: The story ends with the new Justice League being created to fight future threats.
* AnimalSuperheroes: Sees the return of ComicBook/{{Captain Carrot|AndHisAmazingZooCrew}}, who last appeared in ''ComicBook/FinalCrisis''.
* AntiVillain: Earth-10's Overman in ''Mastermen #1''. He feels immense guilt for the lives lost in the creation of his pseudo-utopia, to the point of [[spoiler:becoming TheMole for the Freedom Fighters]].
* ArcNumber:
** 8. ''Pax Americana #1'' even replaces ''ComicBook/{{Watchmen}}'''s 3x3 grid with a 2x4 one.
** Additionally, of the 7 unknown universes, one of them (Earth-14) appears to be splitting in two; this reflects a theme of groups of 7 with a hidden 8th member in Grant Morrison's works (as seen in ComicBook/SevenSoldiers), thought to be a reference to the original 7 members of the ComicBook/JusticeLeagueOfAmerica and their honorary 8th member Snapper Carr.
* ArcSymbol: Doors. Among other things, comic book pages are called "doors" and turning a page is compared to opening a door.
* ArcWords:
** "Who's that knocking at the door?"
** [[spoiler:The word "S.O.S." is revealed to be the keyword to operate the Multiversal Cubes, which Red Racer was able to find reading all the Multiversity books]].
* ArtifactOfDoom: How Creator/GrantMorrison describes ''Ultra Comics #1'':
-->"It's a haunted comic book, actually, it's the most frightening thing anyone will ever read. It's actually haunted—if you read this thing, you'll become possessed."
* AscendedFanboy: Red Racer and President Harley are both comic book nerds who have become superheroes and commanders of superheroes, respectively.
* UsefulNotes/AustralianAborigines: The Thunderer of Earth-7 is an Aboriginal thunder god, an AlternateCompanyEquivalent of [[ComicBook/TheMightyThor Thor]].
* AuthorAvatar: In ''The Multiversity Guidebook #1'', Earth-44's Doc Tornado looks suspiciously similar to Creator/GrantMorrison.
* AvengersAssemble: Essentially the premise of the entire series. With Nix Uotan captured and corrupted by the Gentry, the greatest heroes of the fifty-two Earths are summoned into the Multiversity itself to stop them. The key plot device in the series is the Transmatter cube, existing in each Earth as a creation of that Earth's villain who is influenced by the Gentry. It is responsible for bringing each Earth's heroes to the Multiversity.
* BackForTheDead: The Justice League Axis, the previously established version of Earth-10's Justice League from ''Countdown to Adventure'', appear as corpses in Overman's dream in ''Mastermen #1''.
* BackFromTheDead:
** Lord Volt had been killed in [[ComicBook/CrisisOnInfiniteEarths the first Crisis]], but is now alive again in the current multiverse.
** In ''Pax Americana #1'', Captain Atom is supposed to revive President Harley after the assassination, but this is prevented when scientists kill Captain Atom himself by putting a black hole in his head.
* BadassBoast: In ''The Multiversity #2'', Aquawoman claims that she's the most powerful creature on Earth-11 and does a fine job backing up that claim as she [[spoiler:battles Nix Uotan]].
* BeCarefulWhatYouWishFor: In ''The Just #1'', Damian Wayne says that the world needs a genius supervillain like his mom or his [[ComicBook/RasAlGhul grandad]]. [[spoiler: It has one. He's sleeping with her.]]
* BeingTorturedMakesYouEvil: [[spoiler:Nix Uotan, undergoing horrific treatment at the hands of the Gentry and the Anti-Death Equation, becomes the main antagonist.]]
* BewareTheSillyOnes: Captain Carrot, as bizarrely amusing as he may seem, is no slouch when it comes to heroics or combat. This became apparent in the very first issue, when he [[NoSell nonchalantly shrugged off]] an attack from Earth-8's Behemoth (an {{Expy}} of ''the freaking [[ComicBook/TheIncredibleHulk Hulk]]''), then proceeded to [[CurbStompBattle knock him flat on his ass]] [[OneHitKill with one punch]]. You don't argue with CartoonPhysics.
* BeyondTheImpossible: Nix Uotan wants to solve a Rubik's Cube in 17 moves, the impossibility of which will destroy the universe.
* BiblicalBadGuy: In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', ComicBook/VandalSavage of Earth-40 is heavily implied to be Cain, with the meteor that gave him his powers being the rock that he used to kill Abel.
* BigBadDuumvirate: The Gentry are a cabal of evil beings attempting to infect the multiverse and make all inhabitants thereof become depressed and apathetic to the point of not resisting their invasion.
* BigDamnHeroes:
** [[spoiler:Ultra escapes the time loop established at the beginning of ''Ultra Comics #1'' with a promise that everything's going to be okay now, and manages to be the first hero in the Multiverse to successfully fight back against the Gentry... [[HopeSpot not that it ultimately does any good]] for more than a few seconds.]]
** [[spoiler:Played considerably straighter in ''The Multiversity #2'' when the greatest heroes of 50 worlds charge as one to defeat the Gentry]].
* BlackAndGreyMorality: The conflict in ''Mastermen #1'' ends up being this, concerning the New Reichsmen and the Freedom Fighters.
** With the exception of Overman, none of the New Reichsmen had anything to do with Hitler's original plans and thus aren't concerned with what happened during World War II. But it's blatantly clear that they will still uphold the way of life Hitler established, feel absolutely no shame or guilt about how their paradise was built on the deaths of billions, and hold "under people" in contempt. Overman, for his part, feels incredible guilt and shame for what happened, but feels that he has no way to make it right after going so far. [[spoiler: He actually betrays the New Reichsmen by lying about the Human Bomb's ability to generate explosions while held captive in the Eagle's Nest.]]
** The Freedom Fighters do commit terrorist acts and [[spoiler: have help from Doktor Sivana in terms of technology leading up to the total destruction of Metropolis as the beginning]], but because they want Overman and the system he helped put into power to answer for the unspeakable atrocities and genocide that made it possible. There's also the fact that each of the Freedom Fighters represents minorities that the Nazi Party is still persecuting and trying to destroy.
** To make this conflict even more murky, representatives from both groups are called upon in the final issue to help battle the forces of the Gentry.
* BlandNameProduct: The stories of Earth-7 and Earth-8 are published in other universes by [[Creator/MarvelComics Major Comics]].
* BloodKnight: In ''Mastermen #1'', Leatherwing of Earth-10 espouses that he only believes in "What's real, dirty... and leaves bruises." His "interrogation" of the Human Bomb included beating him with a baseball bat, and overall he feels similar to the Batman of ''ComicBook/AllStarBatmanAndRobinTheBoyWonder''.
* BodyHorror: The ComicBook/FantasticFour expies of Earth-7 are incredibly grotesque, due to their world's corruption by the Gentry. In particular, its Reed Richards counterpart is horrifically stretched.
* BoomHeadshot: [[spoiler:The fate of Cannibal Sivana in the final issue, at the hands (and pistols) of Earth-18's El Diablo]].
* BreakingTheFourthWall: From ''Thunderworld Adventures #1'':
-->'''Shazam''': Hmm, it's you again. I was just practicing my omniscient narrator voice. Come closer, please.
* BreatherEpisode: ''Thunderworld Adventures #1''. The previous four comics had shown possessions, blood sacrifice, suicide, and assassinations, all of them with dark endings. In this one the good guys win, essentially with [[EverybodyLives no fatalities]]. The one discordant note is the SerialKiller Sivana from another universe, but he doesn't get a chance to do anything, along with his DarkerAndEdgier nature being [[StealthParody used as a punchline]].
* TheBusCameBack:
** Five years after ''ComicBook/FinalCrisis'', Nix Uotan and ComicBook/{{Captain Carrot|AndHisAmazingZooCrew}} are finally back. Harbinger and Lady Quark also return, after vanishing post-ComicBook/{{Flashpoint}}, although Lady Quark had apparently been a prisoner of A.R.G.U.S. in the ''Vibe'' book.
** The 90s version of ComicBook/DoctorFate, Jared Stevens, appears on the variant cover to ''Society of Super-Heroes: Conquerors from the Counter-World! #1''. ''The Multiversity Guidebook #1'' shows him as one of the heroes of Earth-13, along with the superheroic version of ComicBook/{{Hellblazer}} introduced in ''ComicBook/TheBooksOfMagic''.
** ''The Just #1'' is an entire bus filled with 90s DC characters, including most of the New Bloods, the third Hourman, Chronos (Gabriel Walker), [[ComicBook/JusticeLeagueOfAmerica Tomorrow Woman]], and Alpha Centurion. Cameos and returns also included [[ComicBook/PlasticMan Off]][[ComicBook/KingdomCome spring]], [[WesternAnimation/TeenTitans Mas y]] [[ComicBook/TeenTitans Menos]], [[ComicBook/JusticeSocietyOfAmerica Jakeem Thunder, Doctor Midnite (Pieter Cross)]], Artemis (as Franchise/WonderWoman), Tempest (as ComicBook/{{Aquaman}}), Chris Kent (as ComicBook/{{Superman}}), and [[ComicBook/GreenArrow Arrowette (Cissie King-Hawke)]].
** ''Thunderworld Adventures #1'' saw the return of the Monster Society of Evil, Uncle Marvel, the Lieutenant Marvels, and Tawky Tawny.
* CallBack:
** Creator/GrantMorrison's map of the Multiverse includes Wonderworld, a dimension that was featured in their ''ComicBook/{{J|usticeLeagueOfAmerica}}LA'' run. News articles have also mentioned that some of their characters from ''ComicBook/AnimalMan'' would appear on one Earth.
** They revisit some concepts they introduced in ''ComicBook/FinalCrisis'', such as President Superman and Earth-23, and Overman and Earth-10, and some they introduced in [[ComicBook/ActionComicsNew52 their run on]] ''ComicBook/ActionComics'', like the mention of Superdoomsday, and Optiman's allies Red Racer and Flashlight.
** Earth-10's Batman is called Leatherwing, which was also the name of a pirate version of Batman (who according to ''The Multiversity Guidebook #1'' is the Batman of Earth-31).
** The variant cover to ''Society of Super-Heroes: Conquerors from the Counter-World! #1'' featured the Batman-esque version of John Constantine called Hellblazer. Morrison created this version in an issue of ''ComicBook/DoomPatrol'', in a dreamworld that had more superheroic versions of the Vertigo-related characters. This world was seen again in the third ''ComicBook/TheBooksOfMagic'' annual.
** Sasha Norman, a.k.a. Sister Miracle of Earth-16 in ''The Just #1'', was first seen in ''ComicBook/SevenSoldiers'' while Shilo Norman was forced to endure alternate lives in the Omega Sanction.
** ''ComicBook/CountdownToFinalCrisis'' gets a mention during ''The Multiversity Guidebook #1'', specifically Superboy-Prime destroying Earth-15.\\
\\
Morrison references it again in ''Mastermen #1''. In Overman's dream of Lord Broken, the bodies at his feet are those of the Justice League Axis, the version of Earth-10's Justice League that Monarch recruited in ''Countdown to Adventure''.
** ''Mastermen #1'':
*** Overman's wife mentions that his cousin, Overgirl, was just a clone created from his stem cells, and if he wanted he could have her replaced. It's said that the original Overman in ''ComicBook/AnimalMan'' had his stem cells harvested by the government to create other heroes, his world's Justice League.
*** Overgirl's death "on a distant world" is another ''ComicBook/FinalCrisis'' reference, and the scene of Overman holding her corpse is a reference to Supergirl's death in ''ComicBook/CrisisOnInfiniteEarths''.
** ''The Multiversity #2'':
*** The corrupted Nix Uotan threatens to unleash his final attack after completing a Rubik's cube in seventeen moves (something that's supposed to be impossible), much like how he regained his powers back in ''ComicBook/FinalCrisis''.
*** The ComicBook/{{Zatanna}} of Earth-13 is named Annataz, which was the name of the Earth-3 Zatanna seen in ''ComicBook/CountdownToFinalCrisis.''
*** Red Racer [[spoiler:and an army of alternate Flashes all use the "infinite mass punch" that Wally West used in Creator/GrantMorrison's very first story arc of ''JLA.'' He even comments that it came from "one of [his] favorite JLA stories."]]
*** [[spoiler:The Empty Hand mentions that the Gentry is still feeding off the carcass of Multiverse-2, which seems to be the pre-Flashpoint Multiverse created after ''ComicBook/InfiniteCrisis''. This seems to highlight the discrepancies between the Multiverse as it is seen here, compared to how it was in ''ComicBook/FinalCrisis'']].
** Nix Uotan is seen with a monkey sidekick, possibly the [[MonkeysOnATypewriter typewriting monkey]] from Morrison's ''ComicBook/AnimalMan'' and/or the monkey that helped Nix restore his Monitor powers in ''ComicBook/FinalCrisis''.
* TheCameo: When Red Racer summons a bunch of Flashes, we get a few. There's the ''ComicBook/BatmanBeyond'' Flash, pre-New 52 Wally West as Kid Flash, the Crime Syndicate's Johnny Quick, pre-Flashpoint Wally West as ''the'' Flash, ''ComicBook/Earth2'''s Jay Garrick Flash and the Flash that Stan Lee created.
* CanonImmigrant:
** ''The Just #1'':
*** Alexis Luthor was originally a descendant of Lex Luthor from the ''[[WesternAnimation/LegionOfSuperHeroes2006 Legion Of Super Heroes]]'' cartoon series. On Earth-16 she's Luthor's daughter.
*** Also on Earth-16 is the version of the Joker's Daughter introduced in ''ComicBook/KingdomCome''.
** ''The Multiversity Guidebook #1'' confirms that the Justice Lords from the ''WesternAnimation/JusticeLeague'' animated series reside on Earth-50, replacing the Wildstorm Comics characters that had been moved to Earth-0 by ''Flashpoint''.
* CaptainErsatz:
** Dino Cop and Spore are the DC versions of the Creator/ImageComics heroes ComicBook/SavageDragon and ComicBook/{{Spawn}}, respectively. In fact, Earth-41 is basically DC's version of Image Comics.
** The heroes of Earth-8 are all based off Creator/MarvelComics characters. The Retaliators (ComicBook/TheAvengers) consist of the American Crusader (ComicBook/CaptainAmerica), Machinehead (ComicBook/IronMan), Behemoth ([[ComicBook/TheIncredibleHulk the Hulk]]), Wundajin ([[ComicBook/TheMightyThor Thor]]), Bug (ComicBook/SpiderMan), Deadeye (ComicBook/{{Hawkeye}}), Red Dragon (ComicBook/BlackWidow), Kite (ComicBook/TheFalcon), Major Max ([[ComicBook/CarolDanvers Captain Marvel]]), Ladybug (ComicBook/SpiderWoman) and Hyperius ([[ComicBook/SquadronSupreme Hyperion]]). There's also the Future Family (the ComicBook/FantasticFour), the G-Men (the ComicBook/XMen), Lord Havok (ComicBook/DoctorDoom), the Power Celestial ([[ComicBook/{{Galactus}} the Power]] [[ComicBook/SilverSurfer Cosmic]] and Celestials), and Stuntmaster (ComicBook/{{Daredevil}}).
** The Thunderer of Earth-7 is based on Wundajin of Earth-8, making him one of ComicBook/TheMightyThor as well. The differences in design between his world and that of Earth-8, and how the heroes of both worlds shared similar or identical codenames, suggested he was an [[UltimateUniverse "Ultimate"]] version, which was confirmed in ''The Just #1''. Similar characters from Earth-7 include Crusader (ComicBook/{{Ultimate|Marvel}} ComicBook/CaptainAmerica), Doc Future ([[ComicBook/UltimateFantasticFour Ultimate Mr Fantastic]]) and Golem ([[ComicBook/UltimateFantasticFour Ultimate The Thing]]). Strangely there also appears to be ersatz of non-ComicBook/UltimateMarvel characters including Walküre (ComicBook/{{Angela|AsgardsAssassin}} who is from the main Marvel Universe) and Devilfist (Creator/DarkHorse's ComicBook/{{Hellboy}}).
** Earth-34, Earth-35, and Earth-36 deserve special mention, in that each of them is loosely based on an already-ersatz-heavy universe (ComicBook/AstroCity, Creator/RobLiefeld's Awesome Comics imprint, and Big Bang Comics, respectively). This means that, yes, they are populated by ersatz versions of characters who are ersatz versions of DC characters.
* CartoonPhysics:
** Captain Carrot invokes this in a fight with a Hulk {{Expy}} on Earth-8, a fight he won by the way. Being squashed flat doesn't do anything to him, because he can just pop back up again.
-->'''Captain Carrot:''' [[BadassBoast Who else wants to argue with cartoon physics?]]
** ''The Multiversity Guidebook #1'' notes that this is true for all of Earth-26. Being destroyed apparently isn't much of a problem for it, either.
* CastOfExpies: See the Captain Ersatz and Expy examples for the very large number of expies in certain universes. A special mention should be made of ''Pax Americana'', which depicts a universe featuring versions of the Charlton Comics heroes who have been turned into Expies of the main characters of ''Watchmen'', who were themselves Expies of the Charlton characters put into a DarkerAndEdgier storyline. So there we have recursive expies of expies.
* CelebrityParadox: At least part of [[Creator/DCComics DC]]'s output in the main [[Franchise/TheDCU DCU]] (Earth-0) is actually inspired by other Earths in TheMultiverse; it's no longer limited to just one Earth as it was pre-''ComicBook/CrisisOnInfiniteEarths'' (where DC's output in Earth-One, the main DCU, was inspired by the heroes of Earth-Two). Creator/MarvelComics have a DC analogue in Major Comics, with their output being inspired by the heroes of Earth-7 and Earth-8.
* ChronicBackstabbingDisorder: The alternate versions of Dr. Sivana keep betraying each other. In ''Thunderworld Adventures #1'', they skimped on Suspendium and left the Earth-5 Sivana to rot. After that, the Earth-42 Sivana is eaten by the Earth-26 Sivana, the Earth-43 Sivana is disposed of by the AxCrazy Sivana, and when ''he'' tries to kill the Earth-26 Sivana he ends up dying as well upon meeting the Justice Riders of Earth-18.
* ClarkesThirdLaw: In ''Thunderworld Adventures'' Sivana replicates Captain Marvel's thunderbolt with a scientific proof and can use his name to invoke a transformation in him and his family who derive their powers from laws of physics instead of mythic figures. When his plan fails so does the proof.
* ColorCharacter: [[ComicBook/BlackWidow Red Dragon]] of [[Creator/MarvelComics Earth-8]] as identified by ''The Multiversity Guidebook #1''.
* ComicBookFantasyCasting: ''The Just #1'', a one-shot about {{legacy hero}}es with [[VictoryIsBoring no evil left to fight]], features an [[ComicBook/GreenArrow Arrowette]] with a scantily-clad, shorthaired look very much like Music/MileyCyrus.
* ComicBooksAreReal: A key concept, according to Creator/GrantMorrison: each Earth has comics featuring characters from other Earths, through which the heroes can keep informed about what's going on elsewhere. For example, ''Mastermen #1'' begins with UsefulNotes/AdolfHitler reading ''ComicBook/ActionComics'' while using the toilet.
* TheConstant: There isn't always a Superman or a Batman equivalent on an alternate Earth, but there's always an Atom-themed character in every issue.
** Lady Quark in ''The Multiversity #1''.
** Al Pratt the Mighty Atom in ''Society of Super-Heroes: Conquerors from the Counter-World! #1''.
** Ray Palmer in ''The Just #1''.
** Captain Adam in ''Pax Americana #1''.

* ContinuityReboot: For Earths 4, 5, 6, 8, 10, 16, 17, 18, 19, 26, 32, 33, 40, 43, and 50, none of which are their original incarnations - whether that's because of a retool, renumbering from the original Pre-Crisis multiverse, or replacing a different universe with the same number. (In the final issue of ''ComicBook/{{Convergence}}'' [[spoiler: we see many pre-New 52 Earths get "recreated" in their ''Multiversity'' forms]].)
** Earth-4 was created and destroyed in ''ComicBook/CrisisOnInfiniteEarths'', and, coming pre-''ComicBook/{{Watchmen}}'', didn't have any influence from it.
** Earth-5's Pre-Crisis analog, Earth-S, was destroyed in the Crisis.
** Earth-6's Pre-Crisis analog was a world where America lost the Revolutionary War and a royal family of superheroes protected the Earth. Its sole survivor was Lady Quark.
** Earth-8's Pre-Crisis analog was a world home to the heroes who debuted after the first Crisis. After ''[[ComicBook/FiftyTwo 52]]'' it was designed as a parody of the ComicBook/UltimateMarvel line of comics and a revision to the Champions of Angor and Extremists. The world still seems to be Marvel-based, but with a team called the Retaliators instead of the Justifiers, for example. The Extremists still exist though.
** Earth-10's Pre-Crisis analog, Earth-X, was a world where the Nazis won and the Freedom Fighters were LaResistance, but had no [[ComicBook/JusticeLeagueOfAmerica Justice League]]. It was destroyed in the Crisis. When it was restored in ''[[ComicBook/FiftyTwo 52]]'' it featured a Nazi version of the Justice League, which hadn't been done before. Conflicting portrayals in ''ComicBook/CountdownToFinalCrisis'' had a standard generic Nazi League and an America covered in concentration camps. In ''Countdown Arena'' a Nazi version of the Ray was chosen as a contestant by Monarch, and it was mentioned the current fuhrer was a woman. Morrison disregarded most of this and reestablished their own version of Earth-10 in ''ComicBook/FinalCrisis''.
** Earth-16 was classified as the universe home to the ''WesternAnimation/YoungJustice2010'' cartoon, although Morrison has stated that they are working on a way that incorporates the TV show with their interpretation of this particular Earth. As of yet, the only incorporation is a one panel reference to the TV show being only a video game on the new Earth-16.
** Earth-17 before the Crisis was a world where all superheroes were created by the government, until Overman (ComicBook/{{Superman}}) contracted an STD, went insane, and destroyed everything. As part of the 52 Earths, Earth-17 was recreated as a world home to the Atomic Knights.
** Earth-18's status as a western world is taken to the extreme. Originally it was introduced in ''Countdown Arena'' as home to the ''ComicBook/JusticeRiders'' Elseworlds. While that is still partially true, the reason this Earth is western-based is because the Time Trapper meddled in its growth, freezing society in a frontier state but allowing it to develop future technology, such as an internet system based off the telegraph.
** Earth-19 was just home to the ''Gotham By Gaslight'' series, but is now a world home to other Victorian versions of different heroes, including the ''Amazonia'' Wonder Woman, who used to be a native of Earth-34 in ''Countdown Arena''.
** Earth-26 was designated [[ComicBook/CaptainCarrotAndHisAmazingZooCrew Earth-C]] Pre-Crisis.
** Earth-31 was established in ''Countdown Arena'' to be the world of ''ComicBook/TheDarkKnightReturns''. It's now a world loosely based on the "Captain Leatherwing" pirate Elseworld, apparently due to a veto by Frank Miller.
** Earth-32 was established in ''Countdown Arena'' as the universe home to ''Batman: In Darkest Knight.'' That seems to still be true, only now this world is home to numerous other amalgamated characters, such as Wonderhawk (Wonder Woman and Hawkgirl), Aquaflash (Aquaman and Flash), Super-Martian (Superman and Martian Manhunter) and Black Arrow (Black Canary and Green Arrow).
** The post-''ComicBook/InfiniteCrisis'' Earth-33 was originally a magic-based world home to the League of Shamans, but since that was seen in ''ComicBook/CountdownToFinalCrisis'' naturally it's been ignored just as everything else from that series was. Earth-33 is now the superhero-less "real world", formerly called Earth-Prime.
** Earth-40, once a pulp SpyFiction world home to "The Justice Files", has been retooled as an EvilCounterpart to Earth-20, which appears to have taken up its mantle.
** Earth-43, a universe home to the ''ComicBook/BatmanVampire'' trilogy, was originally called Earth-1191 in the first Multiverse before the Crisis.
** Earth-50 was originally the universe the Creator/{{Wildstorm}} Universe was set. With the universe now merged with the DCU in ''ComicBook/{{Flashpoint}}''[=/=]''ComicBook/{{New 52}}'', it's now the home of the Justice Lords from ''WesternAnimation/JusticeLeague''. Almost fitting, considering WordOfGod said the Justice Lords were based on ComicBook/TheAuthority.
** Earth-C-Minus, the home of the Justa Lotta Animals, is shown to still exist as of ''Captain Carrot and the Final Ark'', though its official designation in regards to the rest of the multiverse is still unknown. The Justa Lotta Animals show up in ''The Multiversity #2'' fighting Earth-26's Zoo Crew. Whether they're native to Earth-26 or their own Earth is unknown.
* TheCorruption: "Gentrification" - a frightening term that simultaneously evokes the Gentry and themes of identity usurpation and unwilling change.
--> '''Nix Uotan''': We learn from the worst. They make us like them.
* CrapsaccharineWorld: How Overman views the utopia he built on Earth-10 in ''Mastermen #1'', disliking the fact that it was built on the brutal deaths of so many.
* CreepyGood: Abin Sur of Earth-20 from ''Society of Super-Heroes: Conquerors from the Counter-World! #1''. He keeps his distance from the inhabitants of Earth because he's aware that he resembles the world's interpretation of Satan and doesn't want to freak anyone out. Doc Fate doesn't care what he looks like and considers him an ally.
* CrossThrough: The threat of the Gentry is felt throughout the books, which can still be enjoyed individually.
* DarkAgeOfSupernames: The members of The Gentry have such colorful monikers as Dame Merciless, Hellmachine, Lord Broken, Demogorgunn and... [[RobotNames Intellectron]].
* ADayInTheLimelight:
** This is basically the Multiverse's day in the limelight, and what makes this even more significant is that so far, the main DC Universe (Earth-0) and its heroes are not going to be the saviors as they were in every other Multiverse-related catastrophe. The main fighting force is comprised of heroes from different Earths, and so far none of them have been forced to measure up to their Earth-0 counterparts.
** ''The Just #1'' is this for DC's {{Legacy Character}}s.
** The various one-shots are this for their respective universes, which are given less spotlight in the main Multiversity duology.
%% * DeconstructorFleet: The Gentry are this personified in-universe. They actually try to deconstruct Earth-7's Thunderer to death like they did with the rest of his universe.
* DecoyProtagonist:
** ''Pax Americana #1'' isn't so much about the Pax as it is about [[spoiler:President Harley]] and his plan for the world, despite him not being a superhero.
** Also, [[spoiler:Nix Uotan]] and [[spoiler:Earth-23 Superman]] for the main series, both of whom look to be the main characters but don't play much of a role in the anthology structure.
* DontTouchItYouIdiot: In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Doc Fate warns "Atom" Al Pratt away from reading the ''Ultra'' comic, citing it as the most dangerous object in his library.
* DroppedABridgeOnHim: Despite being a main character in ''The Multiversity Guidebook #1'', the only clue to the fate of Earth-42's Dick Grayson fate in ''The Multiversity #2'' is during a brief montage, where it's shown that he was hanged by the Atomic Knights.
* TheEasyWayOrTheHardWay: In ''Mastermen #1'', the Human Bomb heals rapidly from a beating by [[Franchise/{{Batman}} Leatherwing]]. [[Franchise/{{Superman}} Overman]] offers him a chance to make it easy on himself and speak instead of getting a second beating.
* EldritchAbomination:
** The Gentry are a group of evil entities that are roaming the multiverse and destroying every world they come across in [[RealityWarper really horrific ways]]. Just seeing them from another universe crippled Lord Havok and drove him mad. They're also powerful enough to trap Nix Uotan, the last Monitor, in the panels of ''the comic book he's appearing in'' [[spoiler:and convert him into one of their own]]. On top of all that, it's implied that reading the series will let the Gentry into ''our'' universe.\\
\\
In the end, it's even worse. [[spoiler:It turns out that the Gentry are from '''our''' universe, Earth-33. And they are all just servants to an even bigger threat, the Empty Hand, who has all of Earth-42 inhabitants (the Li'l League included) as his servants and spies. And even when the Gentry were beaten, Empty Hand just created new ones like it was nothing and the combined efforts of the entire Multiversity would most likely not be effective as Empty Hand is the personification of our growing real world apathy towards superheroes and comics. And Empty Hand is still digesting and gaining strength from the previous pre-ComicBook/{{Flashpoint}} multiverse. The best the Multiversity can do is establish a watch until they can come up with a way to take down Empty Hand and his Gentry... and the rest of Earth-33 if it comes to it...]]
** Another one is briefly seen in the final issue inhabiting [[HyperspaceIsAScaryPlace the Bleedwall]], but it appears to be neutral in the conflict [[spoiler: and in fact ends up aiding the heroes by [[AlwaysABiggerFish eating Hellmachine]]]].
* EnemyMine: Superdoomsday wrecked havoc on several Earths, but because he and his fellow Overcorp stooge are the only champions of Earth-45, Harbinger is forced to summon them in the final battle alongside several superhero teams he had previously wronged. Members of the Earth-10 New Reichsmen and Freedom Fighters are likewise recruited. However, due to the sheer immensity of the conflict, these antagonistic groups have little opportunity to lock horns.
* EndOfAnAge: By the time ''The Just #1'' begins, the legacies of famous superheroes have not seen any real battles since the previous generation had put an end to war and crime, instead living their lives as celebrities. However, after years of complacency, Earth-16's era of peace comes to an end with the rise of [[spoiler:Alexis Luthor]].
* EvenEvilHasStandards: PlayedForLaughs in ''Thunderworld Adventures #1'', which is set in a LighterAndSofter version of the DC universe populated by the [[ComicBook/{{Shazam}} Marvel family]]. The plot involves Dr. Sivana bringing together an infinite amount of AlternateUniverse versions of himself to create a day in which he can defeat Captain Marvel once and for all. One of these versions, it turns out, is a DarkerAndEdgier Franchise/HannibalLecter-like character who went back in time to horrifically butcher Billy Batson before he became Captain Marvel, and wants other versions to kill. The other Sivanas, who are basically {{Card Carrying Villain}}s, are clearly pretty weirded out.
-->''' Lecter!Dr. Sivana:''' ''Bring them to me! The pretty little '''heroine''', the '''bright boy'''! I can't wait to '''mess them up bad'''.''\\
''' Regular!Dr. Sivana:''' Er... quite.
* EverythingsDeaderWithZombies: In ''The Multiversity #2'', the heroes of Earth-7 are turned into zombies and summoned by the corrupted Nix Uotan during his attack on Earth-8. Meanwhile, the previously deceased Optiman can also be seen during a montage having been brought back the same way.
* EvilChancellor: In ''Pax Americana #1'', the Vice President is revealed to be the story's evil mastermind, trying to prevent the President from being revived from the dead and thereby the best shot at world peace simply so he can be President.
* EvilCounterpart:
** As shown in ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Earth-40 is this to Earth-20, with explicit comparisons between the members of their respective teams:
*** ComicBook/VandalSavage as compared to the Immortal Man, with the meteorite used to create their respective powers being used as [[BiblicalBadGuy the first murder weapon]] or made into a hallowed holy relic respectively.
*** Felix Faust as compared to [[ComicBook/DoctorFate Doc Fate]], in terms of magical prowess.
*** ComicBook/LadyShiva as compared to the Blackhawks, as highly proficient female fighters, albeit with her focusing more on swordplay rather than her good counterparts' gunplay.
*** Blockbuster as compared to [[ComicBook/TheAtom the Mighty Atom]], in terms of ForceAndFinesse.
*** Sinestro and Parallax as compared to [[Franchise/GreenLantern Green Lantern Abin Sur]], with opposing powers of fear versus willpower.
** In ''Thunderworld Adventures #1'', in the Sivanas of the Multiverse, there's a Hannibal Lecter-esque version who is far more bloodthirsty and depraved than the rest of them, who travelled back in time and violently murdered his universe's Billy Batson before he became the Wizard's champion, and as a result has become very bored.
** The majority of the New Reichsmen in ''Mastermen #1'' are evil Nazi doppelgangers of the Justice League of Earth-0.
%% ** [[spoiler:The cannibal Ultras and (possibly) the Empty Hand]] to Ultra Comics.
* EvilKnockoff: ''Thunderworld Adventures #1'':
** Sivana attempts to steal the power of Shazam by... creating a technological version of the Rock of Eternity that is twice the size of the original.
** And then he creates his own version of the Marvel Family using his children.
* {{Expy}}: Creator/GrantMorrison designed an Aboriginal version of ''ComicBook/TheMightyThor'' called the Thunderer. This character and his group seem to be a nod to Mike Friedrich's Wandjina and the ''Champions of Angor'', pastiches of Creator/MarvelComics' ''[[ComicBook/TheAvengers Avengers]]''. They get something of an updated appearance as ''"The Retaliators"'' when President Superman and the team arrive on Earth-8, one dimension shy of Thunderer's homeworld of Earth-7, indicating this world is connected to it in some way. The ComicBook/FantasticFour and ComicBook/DoctorDoom receive similar treatment, becoming Earth-8's Future Family and Lord Havok respectively.
** ''The Just #1'' confirms that the relationship of Earth-7 to Earth-8 mirrors that of the ComicBook/UltimateMarvel universe to the main Marvel universe, with Earth-7's versions being known as the "Essential" versions.
* EyeScream: During his fight with the heroes of multiple words, one of the corrupted Nix Uotan's eyes is destroyed by Aquawoman's lightning. It stays destroyed after he's freed from the Gentry.
* FaceHeelTurn:
** The chief antagonist of the series is a former "cosmic defender", [[spoiler:Nix Uotan]]. He [[RedemptionEarnsLife gets better]] in the last issue.
** In ''The Just #1'', [[MadScientistsBeautifulDaughter Alexis Luthor]] turns evil as a result of reading the Gentry's evil comic book and reprograms Superman's peacekeeping robots into weapons.
** Possibly [[spoiler:Ultra Comics]], given the very heavy implication that he becomes the Empty Hand.
* TheFaceless: In ''Pax Americana'', Sarge Steel--the Vice President's brutal enforcer--has his head cropped off by the panels for most of his appearances in the comic, with a lot of focus being placed on his mechanical arms. Of the two occasions where it isn't, the first is a shot from behind and at a distance while the other is an extreme close-up of his mouth as he lights a cigar.
* FalseUtopia: Earth-10 in ''The Mastermen #1'', an Earth established on the Nazi Party's dogma. It's a very stagnant world as reflected by the architecture. There's no variety, no art of any kind, the cities are literally covered in grossly extravagant eagle statues and swastikas are plastered on everything. This isn't even getting into the rampant racial, religious, and sexual persecutions that have been going on since the 1940s.
* FangThpeak: This is how the snake Sivana speaks, very much averting SssssnakeTalk.
* TheFantasticFaux: Among the heroes on Earth-8 are an ersatz of the Fantastic Four called the Future Family, the individual members being Frank Future (the Reed Richards/Mr. Fantastic stand-in), Fireball (the Human Torch analogue), Ghost Girl (the Invisible Woman stand-in) and Golem (the counterpart to Ben Grimm/The Thing).
* TheFogOfAges: In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Immortal Man notes he's forgotten his own name over the ages. It's not stated if his EvilCounterpart, Vandal Savage, has the same problem.
* TheFourthWallWillNotProtectYou:
** A lot of the captions in issue #1 are threatening warnings along the lines of "You think this is just a comic, but it's '''bait'''. You're bait for '''THEM'''." In his human identity Nix Uotan is reading the same comic, including [[MindScrew scenes from his own life]], and that's how he's pulled into the pan-dimensional crisis.
** Thunderer claims that The Gentry are "pitiless ones from behind the Invisible Rainbow". Given how he uses rainbows to refer to other universes, there's the implication that the fourth wall is incapable of protecting the comic book characters from The Gentry.
** Several pages in ''Pax Americana #1'' seem designed to resemble an eye. The implication is... not promising.
** ''Ultra Comics #1'', the RealWorldEpisode of the series, has its hero warning potential readers that their universe will be endangered if this magazine is read. [[spoiler:At the end, you get infected by The Gentry.]]
** In issue #2, [[spoiler:the newly formed Operation Justice Incarnate trace the Gentry's origin to Earth-33, and state they're coming after them. OhCrap...]]
* FranchiseZombie: In-universe, the Gentry use the power of the Anti-Death Equation to keep Nix Uotan alive so they can corrupt him, a likely allusion to companies refusing to let go of concepts they can squeeze profit out of.
* FromBeyondTheFourthWall: Earth-Prime returns with its own spotlight issue, where the reader becomes its latest superhero.
* FunWithAcronyms: The '''S'''ociety '''o'''f '''S'''uper-Heroes, aka '''S.O.S''' from ''Society of Super-Heroes: Conquerors from the Counter-World! #1''.
* GenderFlip:
** Earth-11 is an entire gender-flipped world. One of the major characters in the series is Aquawoman, their ComicBook/{{Aquaman}} analogue.
** Blitzen, ComicBook/TheFlash of Earth-10 from ''Mastermen #1'', is female.
* GenreRoulette: The series does this deliberately with each issue exhibiting the traits of a particular style of comic genre based on the setting.
* {{Golem}}: According to ''The Multiversity Guidebook #1'', the CaptainErsatz of [[ComicBook/FantasticFour The Thing]] from Earth-7 is named Golem; this is most likely a reference to the Thing's Jewish background.
* GreaterScopeVillain: [[spoiler:The Empty Hand is the representation of ''our'' TooBleakStoppedCaring reaction for comic books, and it's a NeverendingTerror [[YouBastard just because we keep getting fed up with comics, both the dumb stuff and the wonderful]].]]
* GreatOffscreenWar:
** The war between Earth-20 and Earth-40, which involves the former being entirely levelled and conquered by Vandal Savage's forces, sending the heroes on the run... is described entirely in the space of a few pages.
** Earth-33 was the sight of a war between Tor and Epoch. When Tor was defeated in 2240, it managed to take the rest of the millennium with it, turning Earth-33 into a timeless wasteland.
* GroinAttack: The reaction of [[spoiler:[[ComicBook/DoctorFate Doc Fate]] to Doc Faust's desire for a WizardDuel]] in ''Society of Super-Heroes: Conquerors from the Counter-World! #1''.
* GuardianOfTheMultiverse: This is supposed to be Nix Uotan's role, with his fellow Monitors gone. Unfortunately, the Gentry have other ideas for him.
* HangingJudge: The [[spoiler:corrupted Nix Uotan]] becomes this after his disastrous trip to Earth-7. The Earths that break his rules, well, the lucky ones are merely destroyed. Never mind how involved the Gentry were in the violation of those rules.
* HeelFaceDoorSlam: In ''Mastermen #1'', Overman attempts to right the wrongs of his making UsefulNotes/NaziGermany become [[CrapsaccharineWorld the new world]] by [[spoiler:lying about Human Bomb's physiological differences from most people]]. Unfortunately, [[spoiler:[[ComicBook/JimmyOlsen Jürgen Olsen]] figures out that he's not in favor of Hitler's vision and has sympathies with the Freedom Fighters, and thus betrays him, leading to Overman's downfall]].
* HeelRealization: As put by Creator/GrantMorrison in one article regarding ''Mastermen #1'', Overman spent years working for Adolf Hitler, then one day he realized "Oh crap it's Hitler!"
* HemisphereBias: In anticipation of the series, DC Comics released a [[http://www.dccomics.com/blog/2014/08/18/the-map-of-the-multiverse map of the DC multiverse.]] Earth-23 is a world where most superheroes are black; the picture of the planet provided is centered on Africa. (Although note that all other signs point to the United States still being the center of attention there.)
* HenpeckedHusband: In ''Mastermen #1'', Overman's wife/consort, Lena, harbors no sympathy or compassion towards his feelings of guilt or the mourning of his cousin, and is more concerned with demanding he make more youth serum for her before she starts to age. Their relationship is even described as "loveless" and [[spoiler:one of the reasons for Overman's betrayal]].
* HeroAntagonist: Uncle Sam and the Freedom Fighters in ''Mastermen #1'' - they're fighting Nazis, but in a world where the Nazis are pretty much everyone...
* HeroicSacrifice: [[spoiler:Ultra Comics sacrifices himself to protect Earth-33 from the Gentry.]]
* HerrDoktor: In ''Mastermen #1'', the Sivana of Earth-10 is this trope played to the hilt, complete with FunetikAksent (since English is meant to be a dead language on that Earth), ScaryShinyGlasses, and a black leather trenchcoat and hat.
* HistoricalDomainCharacter: UsefulNotes/GeorgeWBush appears in ''Pax Americana #1''. Since this universe seems to have had its own run of presidents, Dubya's appearance might be a symptom of inter-reality bleed.
* HoistByHisOwnPetard:
** Happens several times in ''Thunderworld Adventures #1''. From Dr. Sivana and his counterparts across the multiverse [[spoiler:foiling their own plans of creating a 8th day (Sivanaday) where they're allowed to win by cheating themselves out of [[AppliedPhlebotinum suspendium]] to make it an 8-hour day]], to Lady Sivana (Georgia Sivana) getting tricked into depowering herself by Captain Marvel Junior, out of her own desire to use her beauty to get her way.
** Nix Uotan opening the door for the Gentry is also what allows the things from the Bleedwall to consume Hellmachine.
* HollowWorld: In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Immortal Man mentions in passing that he just walked back from inside the Earth.
* HornedHumanoid: [[Franchise/GreenLantern Abin Sur]] of [[TwoFistedTales Earth-20]] in ''Society of Super-Heroes: Conquerors from the Counter-World! #1''. He is well aware this makes him look like a demon.
* HulkMashUp: One of the heroes of Earth-8 is the Behemoth, who is essentially the Hulk, but blue and looking more like a gigantic baby.
* {{Hypocrite}}: The Question towards Blue Beetle in '' Pax Americana #1''. He chastises Ted for relying too much on technology and cool gimmicks, even though Vic has no problem using technology against Ted and leaving behind calling cards with badass slogans on them.
* HypocriticalHumor: Snake Sivana finds Vampire Sivana's manner of speech irritating:
-->'''Snake Sivana:''' [[FangThpeak Did you find hithhh thhhpeech impediment ath annoying athhh I did?]]
* InadequateInheritor: The major theme of ''The Just #1''. It's not even that the successor heroes are worse or weaker or less effective than the last generation (they frequently aren't, but that's beside the point), it's that the last generation was so good at heroics that they've left nothing for their apprentices and offspring to do.
* ItsAllAboutMe: In ''The Just #1'', Earth-16 is a world where the children of superheroes and supervillains are celebrity darlings since there's no more crime to fight (to the point where the contemporary Justice League roster has done nothing but battle reenactments). The solicits and cover refer to this world as "Earth-Me."
* ItsAllMyFault: In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', the Mighty Atom believes he was responsible for the arrival of the Earth-40 villains, citing that their invasion had begun not long after he looked into the cursed comic book Doc Fate warned him not to read.
* {{Jerkass}}: The majority of the characters in ''The Just'' are self-centered assholes who care little about other people's problems, and that seems to be the point.
* JustShootHim: ''Society of Super-Heroes: Conquerors from the Counter-World! #1'':
** Lady Shiva goes on about how the Blackhawk Squadron will never even realize she's cut them up and butchered them by the time she's done with them, when [[spoiler:they decide to just shoot Shiva as she's gloating.]]
** When Doc Fate meets his counterpart Felix Faust, Faust attempts to pull a magical duel. Fate just [[GroinAttack kicks him in the balls.]]
** The ComicBook/JusticeRiders of Earth-18 deal with [[spoiler:two of the Sivanas]] by simply shooting them.
* KarmaHoudiniWarranty: The SerialKiller Dr. Sivana featured in the ''Thunderworld Adventures'' one-shot is said to have defeated his world's Captain Marvel by using time travel to murder Billy Batson before he became Captain Marvel and subsequently escapes to kill other inhabitants of the multiverse after the other Sivanas are defeated. He ultimately gets his just deserts in the series' conclusion when the ComicBook/JusticeRiders shoot him in the head.
%% * LadyOfWar: Aquawoman, as well as Lady Blackhawk and her Blackhawks Squadron.
* LastOfHisKind: Nix Uotan is the last of the Monitors. Thunderer is the last survivor of Earth-7.
%% * LaughingMad: Lord Broken. Ironically, his invasion of [[spoiler:Earth-4]] is a silent one.
* LeaningOnTheFourthWall:
** In ''Pax Americana #1'', Captain Adam discusses the concept of comic book tropes to a group of doctors, but as he is discussing his ability to read their three dimensional thoughts, [[TheFourthWallWillNotProtectYou he's looking directly at the reader.]]
** In ''Thunderworld Adventures #1'', the Wizard Shazam breaks the fourth wall, telling the reader he was working on his 'omniscient narration'.
* LegacyHero:
** And Villain. This is the basis of ''The Just #1''. Besides already established legacy characters [[ComicBook/{{Batman}} Damian Wayne]], [[ComicBook/{{Superman}} Chris Kent]], [[ComicBook/KingdomCome Off]][[ComicBook/PlasticMan spring]], ComicBook/{{Steel}} (Natasha Irons), [[ComicBook/JusticeSocietyOfAmerica Jakeem Thunder]], [[ComicBook/TheFlash Impulse, Flash]] (Wally West), ComicBook/{{Aquaman}} (Garth), [[ComicBook/WonderWoman Artemis]], [[ComicBook/GreenLantern Kyle Rayner]], and [[ComicBook/TeenTitans the]] [[ComicBook/TheJoker Joker's]] [[ComicBook/KingdomCome Daughter]], Earth-16 features Alexis Luthor (ComicBook/LexLuthor's daughter), Sister Miracle ([[ComicBook/SevenSoldiers Mister Miracle II]]'s daughter), Megamorpho (ComicBook/{{Metamorpho}}'s daughter), Menta (Mento of the ComicBook/DoomPatrol's daughter), and a new version of [[ComicBook/YoungJustice Arrowette]] who is [[ComicBook/GreenArrow Connor Hawke]]'s daughter.
** In ''Pax Americana'', Ted Kord followed from Dan Garrett as ComicBook/BlueBeetle, riffing on both the actual Blue Beetle legacy and the [[ComicBook/{{Watchmen}} Nite Owl]] one.
** Also in ''Pax Americana'', President Harley's dad wrote a Major Comics book featuring a male Major Max, presumably the [[ComicBook/CaptainMarvelMarvelComics Mar-Vell]] to the current version's ComicBook/CarolDanvers.
* LeaningOnTheFourthWall / RealitySubtext:
** In ''The Just #1'', a character reacts in surprise at seeing a comic book and asks if people even read them anymore.
** Similarly this little nugget from ''Pax Americana #1'', which comments on the trend of superhero movies being huge at the box office while actual comic sales are in the gutter.
--> "Heroes are for movies. The super-hero is dead."
* LetsYouAndHimFight: The Multiversity team and the Retaliators come to blows after a bewildered Thunderer knocks out his Earth-8 counterpart.
%% * Letters2Numbers: Intellectron speaks like this.
* LosingYourHead: In ''The Multiversity #2'', [[spoiler:Captain Carrot gets decapitated by the corrupted Nix Uotan. Being a {{Toon}}, however, this does not stop him from continuing to fight, although he is unable to eat his PowerUpFood in order to replenish his superpowers until his head is reattached with Red Racer's help]].
* MadScientist: In ''Thunderworld Adventures #1'', Dr. Sivana takes exception to being called 'mad'. He sees himself more as a radical genius. This is as he teams-up with an assortment of Sivanas from other universe to make an artificial day to take over the world, and get back at Captain Marvel.
%% * MagicVersusScience: Sivana outright states that this is what the battle between him and Shazam is about.
* MeaningfulName: Mr. Stubbs appears to take his name from a chimpanzee in [[https://en.wikipedia.org/wiki/Toby_Tyler;_or,_Ten_Weeks_with_a_Circus Toby Tyler; or, Ten Weeks with a Circus]], a Victorian novel concerning the difference between the glamour of the circus as seen from outside, and the reality of it as seen from the inside.
* MediumAwareness: Ultra Comics sees his thought balloons and thinks they make him look dated, so he switches to first person captions.
%% * MindScrew: Grant Morrison is writing. This is a given.
%% ** ''Ultra Comics #1'' absolutely ''runs'' on this.
* TheMole: [[spoiler:The residents of Earth-42 serve as this for the Empty Hand, acting as its eyes and ears.]]
* MoralityPet: In ''Mastermen #1'', Overman's cousin Overgirl is pretty much the one person he has a clear, emotional connection towards. He cares for her deeply and her death just multiplied the guilt he was already feeling.
* MultipleReferencePun: The CaptainErsatz of ComicBook/SpiderWoman from Earth-8 is named Ladybug, which is both a reference to [[http://en.wikipedia.org/wiki/Ladybug the insect of the same name]] and the fact that she is the DistaffCounterpart of Bug, the ComicBook/SpiderMan [[CaptainErsatz ersatz]] from the same universe.
* TheMultiverse: Set in the post-''New 52'' multiverse, featuring characters from all across its expanse, and the creation of its Justice League.
* MustHaveCaffeine: In ''The Multiversity #2'', thanks to [[ComicBook/{{Zatanna}} Annataz]] of Earth-13, the Blood League of Earth-43 are now vampires who feed on coffee instead of blood.
* [[invoked]] MutuallyFictional: Lampshaded in ''The Multiversity #1'' by Captain Carrot, as the Superman of Earth-23 [[http://mindlessones.com/wp-content/uploads/2014/08/5.jpg reads a copy]] of ''[[ComicBook/ActionComicsNew52 Action Comics #9]]'':
-->"I always suspected that one world's reality is another's fiction. That's why I like {{happy ending}}s!"
* MyDeathIsJustTheBeginning: In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', [[spoiler:ComicBook/VandalSavage corners Immortal Man and Immortal Man kills Vandal Savage in order to end the war. Then Savage reveals that "spilling immortal blood summons Niczhuotan - Destroyer of Worlds."]]
* MyGodWhatHaveIDone: This is Overman's primary characterization in ''Mastermen #1'', as he's the ComicBook/{{Superman}} of a world where the Nazis took over, and he feels horrible knowing the utopia he built was founded on the crimes of Adolf Hitler.
* MythologyGag:
** In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Vandal Savage is heavily implied to be [[BiblicalBadGuy Cain]], just as he was in that position during ''ComicBook/FinalCrisis''.
** In ''Mastermen #1'' Overman holds the dead body of Overgirl aloft in the exact same way Superman did Supergirl on the cover of ''ComicBook/CrisisOnInfiniteEarths #7''.
*** Overman's wife is a self-focused redhead named Lena, whose maiden name is never given. In many continuities, Lex Luthor (who if he isn't bald has red hair) has a relative, either his sister or niece, named ''Lena''.
** In ''Pax Americana #1'', Blue Beetle (I) suggests "the Sentinels" and "the Law" as names for the Pax. ''Sentinels of Justice'' was a proposed Charlton superteam shortly before DC bought the characters, and ''{{ComicBook/LAW}}'' was the 90s DC version.
** At one point during ''Ultra Comics #1'', the titular hero encounters several other DC Comics characters who were also named "Ultra," including Ultra, the Multi-Alien and [[spoiler:Ultraa, who was originally Earth-Prime's sole superhero Pre-Crisis.]]
* NeverBringAKnifeToAGunfight:
** In the end of ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', ComicBook/LadyShiva is facing off against the Blackhawk Squadron, with them having pistols, and her having a SinisterScimitar. [[spoiler:They shoot her dead in a hail of gunfire while she is gloating about how she is going to kill them all.]]
** Doc Faust uses his high grade of magical prowess to make his way through to fight Doc Fate, and prepares himself for a WizardDuel. [[spoiler:Unfortunately for him, that is ''all'' he brought to the table, whereas Doc Fate brought his magical prowess, underhanded tactics, and a gun. He manages to hold off the zombies that come at him with the gun, and summarily defeats Faustus with a GroinAttack.]]
* NightmareRetardant: In-universe, [[spoiler:Intellectron is considered to be this. Ultra utilizes comments laughing at his appearance and calling him "an evil egg" with "evil batwings" in their battle]].
* NoFourthWall: In ''Ultra Comics #1'' the memesmiths, the Gentry and the title character all directly address the reader. Theoretically, at least, the last of these ''is'' the reader.
* NoHonorAmongThieves: The ''chibi'' Sivana in ''The Multiversity Guidebook #1'' thinks the Legion of Sivanas are there to help him conquer his Earth. Instead the snake, vampire and torture porn versions attack and eat him.
* NonIndicativeName: Crops up a couple of times in regards to certain Earth-8 residents and their Earth-7 counterparts.
** Wundajin is the name for a group or cloud and rain spirits from [[Myth/AboriginalAustralianMyths Aborginal Mythology]], yet the superhero from Earth-8 with that name is white, whilst his counterpart on Earth-7 who is [[UsefulNotes/AustralianAborigines aboriginal]] is given the more generic moniker: Thunderer.
** Another superhero is named American Crusader and whilst he does have elements resembling a Holy Crusader, he doesn't have any design elements that say America. Contrast this with his Earth-7 counterpart Crusader, who lacks the American part of the former's name, but is near-identical to ComicBook/{{Ultimate|Marvel}} ComicBook/CaptainAmerica with the WearingAFlagOnYourHead slightly toned down.\\
\\
Subverted in ''Mastermen #1'' which shows an in-universe comic book depicting a [[MediaNotes/TheGoldenAgeOfComicBooks Golden Age]] American Crusader with more American elements played up. This seems to imply that he dropped those aspects in MediaNotes/{{the Modern Age|of Comic Books}} but [[ArtifactTitle kept the name]] and that his UltimateUniverse counterpart is an InUniverse [[RevisitingTheRoots back to basics approach]].
* NoNameGiven / OnlyKnownByTheirNickname: Many characters from the alternate Earths are only known by their codenames. As many of them are counterparts of Earth-0 heroes (most notably the Justice League members), the readers can infer they have the same real names of the Earth-0 ones, but it isn't clearly stated. And there are some universes without clear Earth-0 analogues, like Earth-8, which characters are based on Creator/MarvelComics' ComicBook/TheAvengers, rather than the Justice League. Its only named characters are American Crusader, named [[OnlyOneName Jack]] and Behemoth, real name [[AlliterativeName David Dibble]].
* NoodleIncident: In ''Mastermen #1'', apparently one of the many opponents Overman and his world's league faced was the "Luthor League". No further details on that are given, however.
* OffscreenMomentOfAwesome: In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Abin Sur of Earth-20 defeats Count Sinestro of Earth-40 completely off-panel.
* OhCrap: The wizard Shazam gets a rather darkly funny instance of this when he realizes that he's being overshadowed by Sivana's mechanical Rock of Eternity.
* OneEyedBats: One of the Gentry of is Intellectron, a giant bluish-black egg with one eye and bat wings, which, given how meta Creator/GrantMorrison usually is, may be a comment on DC Comics's obsession with Batman and occasional single-mindedness.
* OnlySaneMan: In ''Thunderworld Adventures #1'', one of the alternate Sivanas is much, ''much'' more restrained than the others, identifying himself as "a man with personal problems," and is greatly disturbed by his insane and violent (and violently insane) counterparts. There's also the fact that he believed the other Sivanas were going to save the world, not enslave it, so he's pretty much the good Sivana counterpart.
%% * OurAngelsAreDifferent: Hellmachine is the "Third Angel of Despair".
* OurPresidentsAreDifferent:
** Kalel/Calvin Ellis, the Superman of Earth-23, is a black Kryptonian, and in his secret identity as Calvin, President of the USA.
** Earth-4's president is assassinated by Peacemaker at the beginning of ''Pax Americana #1''.
* PackagedAsOtherMedium: The cover of ''The Just #1'' resembles the kind of celebrity-interest magazine sold at supermarket counters.
* PaintingTheMedium: [[spoiler:The Empty Hand's]] dialogue bubbles are designed to look like tears in the page, to represent the sheer ''wrongness'' it represents.
* PowerUpFood: Captain Carrot gets his powers from eating his "cosmic carrots," and [[HourOfPower has a set time limit before his powers run out and he needs to eat another one.]]
* PunnyName: Earth-8's American [=CrUSAder=].
* TheQueensLatin: Despite existing on a world where English is a dead language, all the characters in the modern day of ''Mastermen #1'' are written speaking in English, while actually speaking German, with no authorial note stating otherwise, beyond Doktor Sivanna noting to the Freedom Fighters he has difficulty speaking English.
* RaceLift:
** The new version of the Thunderer is Aboriginal.
** The Justice League of Earth-23 consists of black versions of the mainstream DCU heroes.
** In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Doc Fate, the ComicBook/DoctorFate of Earth-20, is a black gunslinger.
** The Wonder Woman of Earth-31 has a darker skin-tone than her Earth-0 counterpart.
** According to one interview, in ''Mastermen #1'', Earth-10's Freedom Fighters represent ethnic, sexual, and religious minorities targeted by the Nazi Party. The Ray is homosexual, Doll Man is a Jehovah's Witness, Phantom Lady is Romani, and Black Condor is African.
* RealWorldEpisode: ''Ultra Comics #1'' features the most literal RealWorldEpisode ever. [[spoiler: This chapter takes place on the real world, but it isn't the world depicted inside the comicbook. Earth-33 (a.k.a Earth-Prime) is the world of the readers themselves. The comicbook Ultra Comics is just a character in the actual story, a comicbook-shaped superhero made of paper and ink (or digital data) that acts like an avatar to its reader to fight The Gentry.]]
* ReallySevenHundredYearsOld: In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Earth-20's Immortal Man has been around somewhere in the region of forty to fifty thousand years, and looks to be in his 20s/30s.
%% * {{Reconstruction}}: ''Thunderworld Adventures #1'' is one of the modern portrayal of Captain Marvel. After years of being depicted in an {{iron|y}}ic and/or {{camp}} light, the good captain [[WhosLaughingNow finally turns the tables on the modern conventions of comic books]].
* RecursiveCanon: In ''The Multiversity #1'', Nix Uotan is reading ''The Multiversity'' comics - specifically, ''The Multiversity #1'' and ''Ultra Comics #1''. Looking closely at the ''Ultra Comics'' issue Nix is reading, Creator/GrantMorrison and Doug Mahnke are residents of Franchise/TheDCU.
%% * RedEyesTakeWarning: [[spoiler:Everyone on Earth-43 when the Empty Hand commands them back to life.]]
%% * RedRightHand: [[spoiler:Sergeant Steel]]'s mechanical prosthesis.
* RetCon: Captain Carrot has always operated under cartoon physics, but they were the burlesqued physics of GoldenAge comics, not the outright ToonPhysics of ''WesternAnimation/LooneyTunes''. No previous incarnation of the character, even relatively recent ones, could possibly have survived [[spoiler: decapitation]].
* RoboticReveal: In ''The Multiversity Guidebook #1'', the [[spoiler:heroes of Earth-42 are revealed to be androids]], explaining how they are incapable of being killed.
%% * RoyalsWhoActuallyDoSomething: Aquawoman, the queen of Atlantis from Earth-11, as well as Lady Quark and Lord Volt.
* SeenItAllSuicide: One interpretation of Sapphire Mason's building dive.
* SelfDeprecation: ''Ultra Comics #1'' makes fun of Morrison's NoFourthWall style of writing by having some internet trolls roll their eyes at Ultra Comics' meta-textual premise.
-->'''[[StrawCritic Troll]]''': Yet ANOTHER comic-about-comics treatise retreading the SAME tired themes. How about a simple adventure story for once?
-->'''[[AudienceSurrogate Ultra Comics]]''': Ha! You and me both!
* ShmuckBait: ''Ultra Comics #1''. Its cover has the eponymous Ultra Comics warning the reader that only they can save the universe and themselves by ''not'' reading this comic. Earth-20's Atom didn't heed the warning in ''Society of Super-Heroes: Conquerors from the Counter-World #1''. [[TheFourthWallWillNotProtectYou Will you?]]
* ShoutOut:
** The Human Torch {{Expy}} from Earth-8 is [[Film/FantasticFour2015 African-American]].
** It's mentioned that the heroes of Earth-8 appear in [[Franchise/MarvelCinematicUniverse extremely popular movies]] on other Earths.\\
\\
In ''The Just #1'', Earth-16's Kyle Rayner vaguely remembers a Bug movie, although it's not clear [[Film/SpiderManTrilogy which one]] [[Film/TheAmazingSpiderManSeries he's thinking of]].
** The Hulk {{Expy}} has the real name of "[[Series/TheIncredibleHulk1977 David]]."
** The House of Heroes is also called [[Myth/NorseMythology Valla-Hal]].
** In ''Society of Super-Heroes: Conquest of the Counter-Earth #1'', the Blackhawks of Earth-20 were designed with the Music/SpiceGirls in mind.
** ''The Just #1'':
*** Chris Kent mentions he had a team up with "the Sandman". Damian then asks if he specifically meant the Creator/NeilGaiman Sandman.
*** The Philip Larkin quote.
** ''Mastermen #1'':
*** The "American Crusader" comic is clearly meant to be a reference to the ''ComicBook/CaptainAmerica'' counterpart from Earth-8, albeit a GoldenAge version. However, the character's design is based off the actual American Crusader, a Golden Age character that fell into the public domain and has been used in both ''ComicBook/TomStrong'' and ''ComicBook/ProjectSuperpowers''.
*** The whole issue can be seen as a shout-out to ''Theatre/TheRingOfTheNibelung'' as detailed [[http://globegander.tumblr.com/post/111537947451/the-ring-of-the-mastermen-der-ring-des-nibelungen here]].
** In ''The Multiversity #2'', Stingray, the Batman of Earth-34, is briefly seen with the same color scheme as the Stingray from ''ComicBook/TheAvengers''.
** Earth-40 Flintstein is based on Rob Liefeld's creation Badrock. Both names are shout-outs to ''WesternAnimation/TheFlintstones'' cartoon: B'''a'''drock is a reference to the show's city B'''e'''drock, while his counterpart Flint'''stein''' is closer to Flint'''stone''' ([[BilingualBonus "stein" is "stone" in German]]).
** Nix ''[[MeaningfulName Uotan]]'' wears [[Film/{{Thor}} a golden eyepatch after losing his right eye]].
* SillyRabbitCynicismIsForLosers: Essentially the theme of ''Thunderworld Adventures #1''; tellingly, it's the only issue of the series where the invasion of the Gentry is completely repelled, because the heroes are just too damn idealistic, good-natured and optimistic to be corrupted.
* SnicketWarningLabel: The series was advertised with warnings not to read the comic, with the fate of the universe depending on it. The end of the first issue also has the narrator shouting that it's not too late if you stop reading ''right now''. [[spoiler:The plot is about a multiversal invasion by {{Eldritch Abomination}}s coming through comic books, which are actually windows into different universes. By the way, ''it is too late'']].
* SquishyWizard: In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Doc Faust proves to be this, [[spoiler:concentrating so heavily on his magical skill that he has no defensive abilities whatsoever outside of those, and goes down in a single GroinAttack]].
* TheStarsAreGoingOut: ''Ultra Comics #1'' ends with constellations going out one-by-one for lack of oxygen, [[spoiler:portraying the rupture of the mental bonds between Ultra Comics and each one of his readers while he dies]].
%% * StraightGay: Red Racer, the Flash of Earth-36, who is apparently in a relationship with his world's Green Lantern, Flashlight.
* SummonBiggerFish: In ''The Multiversity'' #2, [[spoiler: the Earth-5 Marvel Family defeat Hellmachine of the Gentry by throwing him into [[HyperspaceIsAScaryPlace the Bleedwall]], where he is promptly devoured by a larger EldritchAbomination residing there]].
* {{Symbolism}}:
** Of particular note with the Earths on the multiverse map. Earth-10, based on Earth-X, has a red 'X' on it; Earth-11, a GenderFlip of Earth-0, is upside-down relative to the other Earths; Earth-43, home of the Vampire League, is a blood-red shade; Earth-26, an AlternateTooniverse, has a face; and so on.
** Earth-1, which has comparatively very little written about it, is depicted as a glowing ball of light. It's still "cooling", as ''The Multiversity Guidebook #1'' puts it, and has very little established history.
* TakeThat:
** The most distinguishing feature of Earth-8, based on Creator/MarvelComics, on the interactive map is that its heroes "fight with each other as much as they fight the bad guys". Notably, the Behemoth (its version of the [[ComicBook/TheIncredibleHulk Hulk]]) [[https://i.imgur.com/M3ceSaS.jpg transforms into a raging, giant, blue baby]] instead of a jade titan when aggravated.
*** It's taken a bit further in the Hardcover where he's [[SuddenNameChange renamed]] Big Baby.
** The Gentry appear to be manifestations of the stagnation found in mainstream comics. Intellectron, a one-eyed bat-winged creature, in particular is seen as a parody of Creator/DCComics, representing the company's obsession with Franchise/{{Batman}}, a singular vision, and lack of depth perception.
** In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Abin Sur's fight with Count Sinestro and Parallax, as well as [[spoiler: Abin Sur beating both of them on his own]], may be criticism at DC dragging out the emotional entity concept in ''ComicBook/GreenLantern'' and how Parallax has become a diminished threat in recent stories. As well, the use of Parallax [[spoiler:to power the Transmatter Engine for Doc Fate]] can be a reference to how Parallax himself has been used as a tool rather than an actual villain in his own right in his stories since the advent of the ComicBook/{{New 52}}.
** Earth-41's Nimrod Squad is a blatant shot at ''ComicBook/YoungbloodImageComics''.
** ''Thunderworld Adventures #1'' feels like a huge shot at how DC has handled the Marvel Family in the last few years, due to the fact that the Billy, Mary, Freddy, and Wizard of Earth-5 are much more wholesome and well-adjusted compared to their main Earth counterparts. There's also the fact that Sivana, who is still a CardCarryingVillain, is disturbed by an AxCrazy counterpart who makes very unsavory comments about what he did to his world's Marvel Family. Said villain feels sadly similar to the villains who've become common in Earth-0's universe.\\
\\
''Thunderworld Adventures #1'' also comes off as a TakeThat to the New 52 as a whole, seeing how its lack of DarkerAndEdgier elements seems to be what allowed it to repel the Gentry's invasion in the first place. It goes to show that you don't need hyper-realism and grim elements to create a good story, and that the optimism and fun of Pre-New 52 DC still has a place in comics. And, given how well-received ''Thunderworld Adventures'' has been, it's something that hasn't been lost on the general comic-book readership either. Captain Marvel even [[LampshadeHanging lampshades]] how silly the darker and edgier stories are when it comes down to it, and asks just what's wrong with a happy ending.
-->'''Captain Marvel Junior:''' ''[=S.O.S.=]''... They cancelled that book.
-->'''Captain Marvel:''' No wonder. What happened to happy endings? "I'll get out and destroy everything..." HA! I don't know about you. But, that sounds to me, like tomorrow's big adventure!
-->''Crumples up the Gentry's cursed comic-book, chucks it into the trash, and flies off with Mary and Junior to their next big adventure with smiles on their faces.''
** Not to mention that when Sivana takes over the Rock of Eternity, and starts plundering the magic from it, he redecorates it to look like a corporate office, complete with cubicles and potted plants. Possibly a comment on how the comics industry has now become one big corporation.
** The very fact that Billy's alter ego is named, once again, '''Captain Marvel''', outright [[IAmNotShazam disregarding his New 52 renaming as Shazam]].
** ''Pax Americana #1'' is a not too subtle one to Creator/AlanMoore, and how he deconstructed superheroes in a cold mechanical way through the visuals and narrative of ''{{ComicBook/Watchmen}}''.
-->'''Captain Atom:''' I had to take a closer look... I thought the pieces would explain the whole. But... It's hard to love the pieces like... like... I thought I could locate the source of these feelings doctor. Then I realized... [[MyGodWhatHaveIDone What have I done?]] I just killed Butch. My faithful little dog.
** As well as Moore's later attempts at [[{{Reconstruction}} reconstructing]] the genre through his later work ''{{ComicBook/Supreme}}'', and giving a reason as to why Alan Moore or any writer who did {{Deconstruction}} stories can never return to anything upbeat ''and'' meaningful. (Of course, that interpretation brings up some very interesting questions regarding how Morrison views their ''own'' attempts after infamously ultra-super-grimdark stories like their ''ComicBook/KidEternity'' revamp.)
--> '''Captain Atom:''' Except... what if Butch is alive as well as dead? Why not? '''[Another dog similar visually to Butch appears next to the body of the dead dog]''' Hm. Not the same.
** As a further jab at the overdependence on hyper-realistic grimdark story-telling, Earth 31 - previously established as the universe that Frank Miller's Dark Knight series is set in - has been retconned into a world where everyone's a sea-faring swashbuckler with a fancy costume. It also acknowledges human-influenced climate change as a serious issue, showing further disregard for Frank Miller and his right-wing comic fans. (Although, [[https://www.ign.com/articles/2015/10/21/grant-morrison-on-finishing-multiversity-and-whats-next-at-dc according to Morrison]], they ''planned'' to include Dark Knight World, but it was Miller who "didn't want his take on all of that to be seen as just another parallel world." Whether what they did instead was intended as a Take That, they haven't commented on.)
* ThanatosGambit:
** In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Vandal Savage hoped to spill an immortal's blood to summon Niczhuotan, the Destroyer of Worlds, to Earth-20. [[spoiler:Vandal was not picky if he killed Immortal Man, or if Immortal Man killed him.]]
** In ''Pax Americana #1'', [[spoiler:President Harley]] planned to have himself [[spoiler:killed and resurrected]] to rid Earth-4 of the Gentry's curse, simultaneously making him pay for [[spoiler:murdering the first superhero and redeeming him for the crime.]]
* ThatManIsDead: In ''Society of Super-Heroes: Conquerors from the Counter-World! #1'', Doc Fate's greatest fear lies in how he fears nothing because his superhero persona has gradually made him more detached and ruthless, replacing the man he originally was.
* ThirteenIsUnlucky: Earth-13 is a [[Creator/VertigoComics Vertigo-y]] DarkFantasy world where the greatest superheroes are [[ComicBook/{{Etrigan}} Super-Demon]] and ComicBook/{{Hellblazer}}.
* ThoughtBubble: Early in ''Ultra Comics #1'', Ultra Comics uses these at first, until he decides, "'''Thought balloons''' make me look '''dated.'''" He switches to caption-box-based {{Internal Monologue}}s from then on.
-->'''Ultra Comics:''' ''How about I express myself using '''first person narrative captions?'''''
* TimeCrash: Earth-33 has become victim of one, thanks to Epoch and Tor fighting. There's no past, no present, only an endless "now".
* TitledAfterTheSong: The story in ''The Multiversity Guidebook #1'' is called "Maps and Legends", from the Music/{{REM}} song.
%% * TomeOfEldritchLore: ''Ultra Comics #1''.
* TokenGoodTeammate: Among the many alternate Sivanas that have gathered together to invade Earth-5 is one who has won the Nobel Prize and describes himself as basically just a guy who has a few personality issues. He's quite disturbed to find out the rest of the Legion of Sivanas are all criminals and supervillains.
* TookALevelInJerkass: In ''The Just #1'', the older heroes of Earth-16 have no issue with re-enacting major battles for fun, regardless that some of their closest friends and allies actually died in those battles. For example, they have Red Amazo (the combination of ComicBook/RedTornado and Amazo) participate in the recreation of the event that actually created him, but pretty much killed the Red Tornado in the process.
* TorturePorn: Parodied, as the mass villainous team-up of all the alternate versions of [[ComicBook/{{Shazam}} Dr. Sivana]] includes a DarkerAndEdgier "depraved serial killer" Sivana. He wears a Hannibal Lecter mask, and his constant brandishing of rusty surgical instruments and ranting about how he wants to torture the young Marvels to death [[EvenEvilHasStandards creeps the other Sivanas out]].
* TragicHero[=/=]VillainProtagonist: Overman from ''Mastermen #1'', or he may count as a TragicVillain depending on your point of view. He began as a Nazi ComicBook/{{Superman}}, but he's actually incredibly guilt-ridden over what he did in their name, and realizes the world he created needs to be destroyed.
* ATrueStoryInMyUniverse: The comics of the various Earths of the DC multiverse recount the adventures of the heroes of ''other'' Earths in the multiverse.
* TwoGirlsToATeam: [[ComicBook/JusticeLeagueOfAmerica The New Reichsmen]] of Earth-10 from ''Mastermen #1'' appear to have only two female members: [[ComicBook/WonderWoman Brünhilde]] and [[ComicBook/TheFlash Blitzen]].
* UltimateUniverse:
** The aim of ''Thunderworld Adventures'' is to be an updated retool in regards to ''ComicBook/{{Shazam}}''.
** Earth-7 was this to the Major Comics characters of Earth-8, being a pastiche of the ''ComicBook/UltimateMarvel'' continuity.
%% * UniverseCompendium: Or "''Multiverse'' Compendium", rather.
* UnwittingInstigatorOfDoom: Ultra Comics is [[spoiler:exploited by the Gentry as a means to infiltrate the multiverse]]. While he manages to [[spoiler:seal Earth-33 off from them]], he's ultimately unsuccessful in [[spoiler:defeating the villains]].
* UnwittingPawn: A number of characters unknowingly further The Gentry's invasion.
** ''Ultra Comics #1'': [[spoiler: Ultra Comics itself acts as vector of contagion to The Gentry in different worlds ([[TheFourthWallWillNotProtectYou including ours]])]].
%% ** [[spoiler:Batman of Earth-42]].
%% ** Darkseid to the Gentry and [[spoiler:the Empty Hand]].
%% ** ''Mastermen #1'': [[spoiler:Freedom Fighters and Overman]].
* {{Valkyries}}: Two alternate versions of ComicBook/WonderWoman are valkyries.
** Walküre of Earth-8. Due to her universe being an analogue to the Franchise/MarvelUniverse, where due to having [[ComicBook/TheMightyThor Thor]] as a major superhero, Myth/NorseMythology tended to be more dominant than [[Myth/ClassicalMythology Greek Mythology]].
** Brünhilde of Earth-10. Due to [[UsefulNotes/NaziGermany the Nazis]], who amongst other things were noted to have tried to co-opt Myth/NorseMythology, having won World War II in her universe.
* VictoryIsBoring: The heroes of "earthme" in ''The Just'' have so little to do with Superman's army of robots on constant patrol that they do nothing but recreate past victories or throw wild parties.
* {{Villains}}: According to WordOfGod, each one of The Gentry represents a villain archetype taken to its limit. Their agents in each universe also mirror those concepts.
** AxCrazy / BedlamHouse: Lord Broken (Vandal Savage, cannibal Doctor Sivana, [[spoiler:Nazi Doctor Sivana]])
** EvilGenius: Intellectron (Felix Faust, Doctor Sivana, [[spoiler:Alexis Luthor]])
** FemmeFatale: Dame Merciless (Lady Shiva, Georgia Sivana, [[spoiler:Alexis Luthor]])
** TheHorde: Demogorgunn (Faust's Zombies, Legion of Sivanas, [[spoiler:Superman Robots, Brainwashed Li'l League]])
* WholeCostumeReference: In ''Mastermen #1'', the Sivana of [[ThoseWackyNazis Earth-10]]'s outfit is exactly the same as [[Film/RaidersOfTheLostArk Major Toht]]. Fitting, considering what his world is like.
* WizardDuel: Amusingly subverted in ''Society of Superheroes: Conquerors from the Counter-World! #1''. The issue appears to set up a MirrorMatch between Doc Fate and Doc Faust, but when Faust shows up before Fate, [[spoiler:Fate just kicks him in the balls and drags him away]].
%% * WomanScorned: [[spoiler:Alexis Luthor.]]
* WouldHurtAChild: In ''The Multiversity Guidebook #1'', the alternate Sivanas have no problem luring a chibi Sivana into their number so that one of them can eat him. [[spoiler:Given everyone else on his world was a robot, that Sivana was found unpalatable]].
* WoundedGazelleGambit: In ''Mastermen #1'', [[spoiler:with help from Overman, the Human Bomb threw off Leatherwing and the rest of the New Reichsmen by pretending to be gravely injured by Leatherwing's interrogation, giving him the chance to wait to break free and then destroy the Eagle's Nest]].
* YourTerroristsAreOurFreedomFighters: The "Freedom Fighters" of Earth-10 are flat out said in ''The Multiversity Guidebook #1'' to be terrorists. Their actions in ''Mastermen #1'' show this in full, especially after they received [[TheCorrupter help]] from Herr Doktor Sivana.
