DC Universe

The DC Universe (DCU) is the shared universe in which most stories in American comic book titles published by DC Comics take place. In context, the term "DC Universe" usually refers to the main DC continuity. It contains such well-known superheroes as Batman, Superman, Wonder Woman, the Flash, Green Lantern, Aquaman, Green Arrow, Captain Marvel, Martian Manhunter, and Cyborg; as well as teams such as the Justice League, the Justice Society of America, the Suicide Squad, Doom Patrol, and the Teen Titans. It also contains well-known supervillains, including the Joker, Lex Luthor, the Cheetah, the Reverse-Flash, Sinestro, Black Manta, Deathstroke, Black Adam, Brainiac, and Darkseid.

The term "DC Multiverse" refers to the collection of all continuities within DC Comics publications. Within the Multiverse, the main DC Universe has gone by many names, but in recent years has been referred to by "Prime Earth" (not to be confused with "Earth Prime") or "Earth 0".

The main DC Universe, as well as the alternate realities related to it, were quickly adapted to other media such as film serials or radio dramas. In subsequent decades, the continuity between all of these media became increasingly complex with certain storylines and events designed to simplify or streamline the more confusing aspects of characters' histories.
