List of DC Multiverse worlds

• Earth-Zero's only appearance was in a single panel in Infinite Crisis #6. It is an homage to Bizarro World, with its population of Bizarros and cubical shape. The original Bizarro World was not a parallel Earth, but another planet that existed in the same universe as Earth-One.
• One of the proposed names for the post-Zero Hour DC Universe after a somewhat definitive timeline was established.^[1]

• The default Earth for most of DC's comics during the time the original Multiverse construct was in use, Earth-One was by far the most "populous" and widely explored, and it retained dominance over the other four worlds which merged with it during the Crisis on Infinite Earths storyline. The DC Universe's "official" continuity post-Crisis took place on a "merged" Earth-One, as the Crisis revealed that this universe had been the core reality until the rogue Guardian Krona fractured reality at the dawn of creation, creating both the Multiverse and the Antimatter Universe.
• First described as a distinct Earth in Flash (vol. 1) #123 (Sept. 1961), first named in Justice League of America (vol. 1) #21 (Aug. 1963).

• Politically, Earth-Two was distinctly different from the Earth-One template modelled after Earth-Prime. For example, Quebec was an independent nation autonomous from Canada, South Africa had abolished apartheid sooner, and the Atlantean countries of Poseidonis and Tritonis were ruled by a queen, not a king, their inhabitants displaying surface-dweller features and no capacity for underwater survival, as the Atlantis continent had been raised to the surface (the model was the Atlantis seen in Golden Age Wonder Woman stories).
• First described as a distinct Earth in Flash(vol. 1) #123 (Sept. 1961), first named in Justice League of America #21 (Aug. 1963).

• History was "backwards": American Christopher Columbus discovered Europe; Britain won its freedom from the United States; President John Wilkes Booth was assassinated by actor Abraham Lincoln; the United States flag's colors were reversed: black stars on a red field, with alternating blue and black stripes; and all superheroes are supervillains and vice versa.

• This Earth was introduced at the beginning of Crisis, and disappeared less than a year later.
• Named in Crisis on Infinite Earths #1 (Apr. 1985)

• Transported by the Phantom Stranger to a universe with no Krypton and no superheroes, the Earth-One Batman prevents the murders of the Earth-Five versions of his parents and inspires this Earth's Bruce Wayne to grow up to become Batman.
• Named in Absolute Crisis On Infinite Earths (2006)

• Earth-Six is apparently ruled by a royal family of superheroes (Lord Volt is referred to as the king, and he mentions his family's reign over Earth). On this Earth, America lost the Revolutionary War, and technology appears to have advanced more rapidly than on Earth-One. Earth-Six was destroyed in Crisis with only Lady Quark surviving.

• The Anti-Monitor saved Dark Angel, just as the Monitor had saved her counterpart Harbinger. The only known survivor of Earth-Seven, Dark Angel escaped the compression of the Multiverse to torment Donna Troy across several lifetimes.

• Johnny Thunder's evil Earth-One counterpart created Earth-A when he used Johnny’s Thunderbolt to alter the origins of the Justice League, replacing them with his own henchman, whom he granted powers and skills identical to the Justice League's. "A" stood for "alternate", since it was an alternate timeline of Earth-One.

• This Earth was never specifically depicted, but was suggested to exist in a letters column by DC editor/writer Bob Rozakis as a possible explanation for certain non-continuity stories or character traits (for example, stories that showed Catwoman committing murder with no qualms, despite being established that she did not engage in that kind of activity); tongue-in-cheek, Rozakis designated it "Earth-B" in "honor" of writer Bob Haney, whose Brave and the Bold stories were then-notorious examples of such continuity errors. ICG's Official Crisis Cross-over Index theorized that DC Challenge took place on this earth which given the involvement of Oan Guardians would make it an alternate Earth-One timeline.

• This world is populated with anthropomorphic animals, who appear as comic book characters on Earth-One.

• This Earth (like Earth-C) is populated by anthropomorphic animals. Events and characters on this world paralleled those of Earth-One; additionally, events and characters on Earth-C-Minus were considered fictional on Earth-C (with Captain Carrot's alter-ego employed as the cartoonist of the Just'a Lotta Animals comic book series), in the vein of Earth-Two heroes’ only appearing as comic book characters on Earths-One and Prime.

• Earth-D featured a more ethnically diverse version of several Earth-One heroes, such as an Asian Flash, a black Superman, and an American Indian Green Arrow.

• A world created by Superman to see if a world without a Superman, nor any superheroes, could work. It is revealed at the end of the issue that Earth-Q is a real world Earth, as Friedrich Nietzsche is seen creating his famous Übermensch, or "Superman", concept, and Joe Shuster is shown drawing the first modern Superman on the cover of Action Comics (vol. 1) #1 (June 1938).

• One of three Earths named by Alexander Luthor in Infinite Crisis in his search for the perfect Earth; Superman, Batman, Wonder Woman, Robin, Superboy, and Supergirl are Aztec warriors with the "Superman Family" (Superman, Supergirl, and Superboy) and the "Batman Family"(Batman, Robin, and Wonder Woman) fighting against each other.

Perry White is a retired Matador, Professor Potter is a cranky boss at the World's Fair, and Clark Kent is a science-fiction writer and secretly a Joker-masked villain that leads the LUTHAR League. Jimmy gains Superman-like powers and becomes Steelman, a superhero wearing a combination of Superman and Batman's costumes. Designated Earth-X on the cover and in the story title, but not in the story itself.

• On this world, Nazi Germany won World War II, and the Freedom Fighters, originally from Earth-Two, fought to defeat them. Most Quality Comics publications chronicled adventures from this Earth.
• Named in Justice League of America (vol. 1) #107 (Oct. 1973)

• A world based on drug culture that appeared briefly in Grant Morrison's Animal Man comic series. Dreamworld is not an official designation, but is assumed from the name of this world's premier superhero team.

• The first parallel Earth to be featured in DC Comics was visited by the Earth-2 Wonder Woman, who worked with her counterpart to battle the conqueror Duke Dazam. This Earth appeared to be technologically less advanced than Earth-2, with Dazam's navy using oar-powered ships. "Tara Terruna" translates from that Earth's language to mean "Wonder Woman."

• This Earth was created by Alexander Luthor during Infinite Crisis, when he merged Earth-154 with Earth-462, which equals 616, the number used to identify the Marvel Universe.

• The Earth that Pariah comes from was never officially named. Fans often dubbed it "Earth-Omega" as it was the site of the "beginning of the end".^[3]

• Qward's universe has been described as a "universe of evil". Qwardian society seems to be dominated by a philosophy of selfishness and greed. This could be the effects of millennia of inescapable rule by the Weaponers.

This Earth was rendered lifeless by three super-powered villains. It was not seen again until the "End of an Era" Legion story-arc prior to Zero Hour.

• A post-Crisis Antimatter Earth with a Crime Syndicate whose motto is "Cui Bono?" ("Who profits?"), inspired by the pre-Crisis Earth-Three. Originally, the Luthor of the CSA Earth, upon discovering the positive-matter Earth, named his world, "Earth 1", and the positive-matter Earth, "Earth 2" (no hyphens). Subsequent appearances revised the naming convention and simply referred to it as the Antimatter Universe's Earth, and also established that the CSA's Earth existed in the same Antimatter Universe as Qward.

• The Fourth World is a continuum inhabited by the New Gods. Its two main worlds, New Genesis and Apokolips, are mirror reflections of each other: New Genesis, the bright, glorious home ruled by Highfather, and Apokolips, the fiery, horrific home of the evil warlord Darkseid and his minions. Inhabitants of these worlds have been frequent visitors to the Earth-One and Post-Crisis Earth, but it has been shown that they could venture into any number of alternate worlds. The Fourth World was not affected by the Crisis on Infinite Earths.

• In 1993, word of a gang war on Paris Island resulted in Mayor Jefferson ordering enforcement officials to spray every gang member present with an experimental tear gas laced with a radioactive marker that would allow the police to track the participants down later. Survivors then became known as "bang babies" given mutagenic abilities.
• Following the death of Darkseid (as chronicled in Final Crisis in 2009), the space-time continuum was torn asunder, threatening the existence of both the Dakotaverse and the mainstream DC universe (containing New Earth). Dharma was able to use energies that he harnessed from Rift (upon that being's defeat) to merge the two universes, creating an entirely new continuity.^[6]

• After the destruction of Alexander Luthor's Multiverse Tower in Infinite Crisis, the parallel Earths that had been created were merged into a new single world dubbed "New Earth". New Earth is currently the core existence of the DC Universe.
