Captain Marvel (DC Comics)
Captain Marvel, also known as Shazam, is a fictional superhero appearing in American comic books published by DC Comics. The character was created in 1939 by artist C. C. Beck and writer Bill Parker, and first appeared in Whiz Comics #2 (February 1940), published by Fawcett Comics. He is the alter ego of Billy Batson, a boy who, by speaking the magic word "Shazam", can transform himself into a costumed adult with the powers of superhuman strength, speed, flight, and other abilities.
Based on book sales, the character was the most popular superhero of the 1940s, outselling even Superman, and Fawcett expanded the franchise to include other "Marvels", primarily Marvel Family associates Mary Marvel and Captain Marvel Jr., who can share Billy's powers. Captain Marvel was also the first comic book superhero to be adapted into film, in a 1941 Republic Pictures serial titled Adventures of Captain Marvel.
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. In 1972, DC licensed the Marvel Family characters from Fawcett and returned them to publication, acquiring all rights to the characters by 1991. DC has since integrated Captain Marvel and the Marvel Family into their DC Universe and have attempted to revive the property several times, with mixed success. Due to trademark conflicts over another character named "Captain Marvel" owned by Marvel Comics since 1967, DC chose to publish the character's adventures under the comic book Shazam! for many years, leading many to assume that this was the character's name. DC later renamed the character "Shazam" when relaunching its comic book properties in 2011.
