what's the difference between shazam and black adam
Black Adam Black Adam is a fictional DC Comics supervillain and occasional antihero;[1][2][3][4][5][6][7] an adversary of the superhero Captain Marvel, also known as Shazam. Black Adam was created by Otto Binder and C. C. Beck in 1945 as a one-shot villain for the first issue of Fawcett Comics' The Marvel Family comic book; 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.
Captain Marvel (DC Comics) Fawcett ceased publishing Captain Marvel-related comics in 1953, partly because of a copyright infringement suit from DC Comics, alleging that Captain Marvel was a copy of Superman.[4] In 1972, DC licensed the Marvel Family characters from Fawcett, and returned them to publication. By 1991, DC had acquired all rights to the characters. DC has since integrated Captain Marvel and the Marvel Family into their DC Universe and has attempted to revive the property several times, with mixed success. Due to trademark conflicts over another character named "Captain Marvel" owned by Marvel Comics,[5] DC has branded and marketed the character using the trademark Shazam! since his 1972 reintroduction.[6] This, in turn, led many to assume that "Shazam" was the character's name. DC later officially renamed the character "Shazam"—and his associates the "Shazam Family"—when relaunching its comic book properties in 2011.[7] Captain Marvel/Shazam and his family battle an extensive rogues' gallery, primarily archenemies Dr. Sivana and Black Adam.
