Deadshot 1 credits

Deadshot is a supervillain appearing in American comic books published by DC Comics. Created by writer David Vern Reed and artist Lew Sayre Schwartz based on a concept from Bob Kane, the character first appeared in Batman #59 (1950). Introduced as a gun-toting criminal in a tuxedo, top hat, and domino mask, Deadshot was only intended to be a one-off villain for the superhero Batman, but writer Steve Englehart and artist Marshall Rogers revived, redesigned, and popularized the character in Detective Comics #474 (1977), which featured the debut of his wrist-mounted guns, reticle emblem, and mask with a built-in targeting sight that have since become Deadshot's visual motif.
