Shazam (/ʃəˈzæm/), also known as The Captain and formerly known as Captain Marvel, is a superhero in American comic books originally published by Fawcett Comics and currently published by DC Comics. Artist C. C. Beck and writer Bill Parker created the character in 1939. Shazam first appeared in Whiz Comics #2 (cover-dated Feb. 1940), published by Fawcett Comics. Shazam is the alter-ego of William Joseph "Billy" Batson, a young boy who is granted magical powers by the Wizard by speaking the magic word "SHAZAM!", an acronym of six "immortal elders": Solomon, Hercules, Atlas, Zeus, Achilles, and Mercury, and transforms into a costumed adult superhero with various superpowers derived from specific attributes of the aforementioned elders.
The character battles evil in the form of an extensive rogues' gallery, most of them working in tandem as the Monster Society of Evil, including primary archenemies Black Adam, Doctor Sivana and Mister Mind. Billy often shares his powers with other children, primarily his sister Mary Batson and their best friend/foster brother Freddy Freeman, who also transform into superheroes and fight crime with Billy as members of the Marvel Family (also known as the Shazam Family or Shazamily). The character also serves as a notable member of several teams, including the Justice League and various other derivatives, Justice Society of America, and the Teen Titans.
