Frank Miller's Batman wasn't supercool enough to get in.
As expected of The Multiversity's basic premise, the entire run is dedicated to the weird and wonderful variations of well-established characters and stories. The Earths that get their own individual issues are:- Earth-4, where the Charlton Comics characters - The Question, Blue Beetle, Captain Atom, etc. - are the heroes of a Watchmen-influenced world.
- Earth-5, the world of Captain Marvel and the Marvel Family.
- Earth-10, a world where Kal-L was found by the Nazis, and grew up to become Overman. With the help of retro-engineered Kryptonian technology - and, when he was old enough, Overman himself - the Nazis won World War II. In guilt over the Nazis' atrocities, Overman turned his Earth-into a pseudo-utopia; the last English-speaking rebels, Uncle Sam and the Freedom Fighters, fight Overman's Justice League.
- Earth-16, with the children of the main DC universe's heroes and villains - Chris Kent as Superman's son, Damian Wayne as Batman's son, etc. - plus DC's '90s supers.
- Earth-20, a pulp-style world featuring Doc Fate and the Society of Super-Heroes, who include Green Lantern Abin Sur, Immortal Man, the Mighty Atom, and the Blackhawks.
- Earth-33, a.k.a. Earth-Prime, which is basically our world, with the reader being its latest superhero. It's also the world of origin for the Gentry, who are designated as "Hostile Independent Thought-Forms" by the reader and his/her haunted comic book, Ultra Comics. The Gentry's creator, the Empty Hand also reigns here, as he is implied to be the personification of our real world apathy towards superheroes and comics in general who is still digesting the previous iteration of the Multiverse lost during Flashpoint.
- The other worlds of the multiverse include:
- Earth-0, the main DCU.
- Earth-1, the world home to the Superman: Earth One, Batman: Earth One and Teen Titans: Earth One graphic novels. There is also a version of Wonder Woman living on this Earth.
- Earth-2, as featured in the comic of the same name, where younger versions of DC's Golden Age heroes arose in the modern day in the wake of an invasion from Apokolips.
- Earth-3, the Mirror Universe of Earth-0, ruled by the Crime Syndicate of America; it was destroyed just before Forever Evil (2013).
- Earth-6, the world now home to the stories from Just Imagine... Stan Lee Creating the DC Universe.
- Earth-7 is already destroyed upon the arrival of Nix Uotan, but appears to have been a Marvel pastiche like Earth-8, below. However, pastiches of DC characters can be seen among the dead, so it's likely this Earth-was a mix-up in homage to the many DC and Marvel crossover stories. The guidebook confirms that it is (or was) the equivalent to Ultimate Marvel.
- Earth-8, a Marvel Comics pastiche, for example featuring the Retaliators and the G-Men.
- Earth-9, the Tangent Comics universe.
- Earth-11, which includes female versions of the main DCU's heroes and villains, and male versions of its heroines and villainesses. This is a world where the Amazons of Themyscira had greater influence on society's advancement, to the point that women were given more freedom and helped shape Earth's future.
- Earth-12, the DC Animated Universe world, currently in the era of Batman Beyond.
- Earth-13, home to a dark, magical Justice League called the League of Shadows, including Superdemon, Hellblazer (based on the Batmanesque version from Doom Patrol #53 and Books of Magic Annual #3), and Fate (the 90s version with the ankh scar). The world is in a state of perpetual twilight, there are 13 months in the year, and 13 hours in every day.
- Earth-15, a perfect world that was destroyed by Superboy-Prime. All that's left is a Cosmic Grail that was hidden in another world.
- Earth-17, an Earth ravaged by atomic destruction. Humanity lives in domed cities, and the Atomic Knights of Justice are led by Adam Strange.
- Earth-18, a Western-style world featuring the Justice Riders, who ride on Steampunk horses. On this world, the Time Trapper froze the state of progression so that, even with many 21st Century based technological advances, society is still a frontier world.
- Earth-19, a world currently in the era of Edwardian England, home to the Bat Man, the Wonder Woman, the Accelerated Man, and the Shrinking Man. Bruce and Diana are based on Gotham By Gaslight and Amazonia respectively note .
- Earth-21, the DC: The New Frontier universe.
- Earth-22, the Kingdom Come universe.
- Earth-23, home of President Superman, where the world's greatest heroes are black (which can mean that they're black in the main DCU, as with Steel and Vixen; that a black holder of the legacy in the main DCU is Earth-23's primary holder, as seems to be the case with Green Lantern; that they're black versions of the hero, as with Superman; or that they're completely unique). The major exception is Batman.
- Earth-26, an Alternate Tooniverse where Captain Carrot and His Amazing Zoo Crew! reside.
- Earth-29, the cube-shaped Bizarro Universe.
- Earth-30, the Superman: Red Son universe.
- Earth-31, a world ravaged by tsunamis and earthquakes, where modern pirates roam the seas. Captain Leatherwing and his crew of the Flying Fox act as a force for good.

- Earth-34, an Astro City pastiche, home to the heroes of Cosmoville.
- Earth-35, a pastiche of Rob Liefeld's Extreme Studios comics, including Supremo and Majesty, Queen of Venus. The premier superteam of this world is the Super-Americans.
- Earth-36, a world home to a team called Justice 9, based off Big Bang Comics.
- Earth-37, a world based off the works of author Howard Chaykin, such as Batman: Thrillkiller.
- Earth-38, the world of Superman & Batman: Generations, where Batman and Superman debuted in 1938, aged normally, and had families.
- Earth-39, a world based off the works of artist Wally Wood, home to the Agents of W.O.N.D.E.R.
- Earth-40, an Evil Counterpart to Earth-20 where villains rather than heroes triumph, featuring Lady Shiva, Vandal Savage, Count Sinestro, Blockbuster, and Doctor Felix Faust as the Society of Super-Villains.
- Earth-41, home to Spore and Dino-Cop, a world where so many heroes differ in terms of style and ideology, it's as if they were each dreamed up by individuals who had specific images and ideals of their heroes.
- Earth-42, home to chibi-like versions of the Justice League known as the Li'l Leaguers.
- Earth-43, which has a Vampire League and is home to the Batman Vampire Elseworlds trilogy.
- Earth-44, the world of the Metal League, a fusion of the Justice League and the Metal Men, led by Doc Tornado.
- Earth-45, an Earth where Superman as a concept became perverted and corrupted by mass marketing and turned into the hyper-edgy Superdoomsday, whom later went on a homicidal rampage killing the Supermen of other Earths before being stopped by the Superman of Earth-0 in Action Comics (New 52).
- Earth-47, a world where The '60s never ended, home to the Love Syndicate of Dreamworld and immortal teenage president Prez Rickard.

- Earth-50, home to the Justice Lords from the DCAU.
- Earth-51, the world of Jack Kirby's DC creations.

- In Superman (Rebirth) story "Multiplicity", Earth-14 is the home of the Justice League of Assassins. From what's seen of it, it looks to be an After the End Mad Max-style world.
- The Terrifics revealed Earth-25 to be the home of Tom Strong and other America's Best Comics characters.
- After the events of Dark Crisis, all the rest of the unknown universes were revealed.
- Earth-24, home to DC Bombshells, a world where all superheroes are women fighting for their freedom during World War II.
- Earth-27, home to the Jurassic League, a prehistoric world where the world's greatest heroes are dinosaurs.
- Earth-28, a world ravaged by Apokolips with the JSA disbanded, the age of Heroe's ending brought us a new era of Mech-based heroes. (DC: Mech)
- Earth-46, where a more grim Gotham City is home to a younger Batman and a gallery of new psychotic villains.
- Earth-49, after the death of Lois Lane at the hands of the Joker, Superman decided that enough was enough. Now crime and wars will cease to be under the watchful eyes of Superman and his Regime.
