Earth-31 (Universe) (DC Comics)
The Batman from Frank Miller's Batman: The Dark Knight Returns and its spin-offs, Batman: The Dark Knight Strikes Again and All Star Batman and Robin the Boy Wonder is a tired vigilante in a much darker, edgier setting home to Miller's own new interpretations of various DC characters. This alternative Batman resided on Earth-31.

Earth-31 is one of fifty-one divergent realities that branched from the core New Earth reality during the recreation of the Multiverse shortly following the events of Infinite Crisis. Home to a darker, more brutal version of Batman fighting crime and the corrupt Gotham City Police Department alike alongside his young partner Robin, much to the concertation of both the public and the burgeoning Justice League. Ultimately, Batman retired in his 40s after the death of second Robin Jason Todd, as well as increased public outcry against superheroes driving most of his contemporaries into exile. He returned a decade later alongside new Robin Carrie Kelley to save Gotham from the unchecked street crime and political corruption that had thrown it into chaos, eventually assembling an army to take the country back from a corrupt administration headed in secret by Lex Luthor that had effectively enslaved the remaining heroes such as Superman, Wonder Woman and Captain Marvel.
