Captain Marvel, also known as Shazam (), is a fictional superhero appearing in American comics originally published by Fawcett Comics, and currently published by 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 Doctor Sivana, Black Adam, and Mister Mind.
