Shazam is a comic book superhero appearing in publications by American publisher DC Comics. Artist C. C. Beck and writer Bill Parker created the character in 1939. Captain Marvel first appeared in Whiz Comics #2 (cover-dated Feb. 1940), published by Fawcett Comics. He is the alter ego of Billy Batson, a boy who, by speaking the magic word SHAZAM! (acronym of six immortal elders: Solomon, Hercules, Atlas, Zeus, Achilles, and Mercury), can transform himself into a costumed adult with the powers of superhuman strength, speed, flight and other abilities. The character battles an extensive rogues' gallery, primarily archenemies Dr. Sivana, Mister Mind, and Black Adam.
