Elseworlds

Elseworlds is the publication imprint for a group of comic books produced by DC Comics that take place outside the company's canon. The imprint presents narratives in which existing characters, such as Batman, or storylines are introduced to an entirely new idea or concept. The "Elseworlds" name was copyrighted in 1989, the same year as the first Elseworlds publication, and supplanted the previous Imaginary Stories series that employed the same premise.

Unlike its Marvel Comics counterpart What If...?, which bases its stories on a single point of divergence from the regular continuity, most Elseworlds stories instead take place in entirely self-contained continuities, with the only connection to the canon DC continuity being the presence of familiar DC characters.
