Black Adam is a fictional supervillain and occasional antihero appearing in American comic books published by DC Comics. Created by Otto Binder and C. C. Beck, the character is the archenemy of the superhero Captain Marvel, also known as Shazam. Black Adam first appeared as a one-time villain for the first issue of Fawcett Comics' The Marvel Family comic book (December 1945). However, Black Adam was revived as a recurring character after DC Comics first licensed and then acquired the Fawcett characters and began publishing Captain Marvel/Marvel Family stories under the title Shazam! in the 1970s

As originally depicted, Black Adam was a corrupted, ancient Egyptian predecessor of Captain Marvel, who fought his way to modern times to challenge the hero and his Marvel Family associates. Since the turn of the 21st century, however, Black Adam has been re-defined by DC Comics writers Jerry Ordway, Geoff Johns, and David S. Goyer as a corrupted antihero attempting to clear his name and reputation. Featured roles in such comic book series as Justice Society of America (JSA), Villains United, Infinite Crisis, and 52 have elevated the character to an unprecedented level of prominence in the overall universe of DC Comics characters.
