Whiz Comics #2 (cover-dated Feb. 1940) was published in late 1939. Captain Marvel, the comic's lead feature, introduced audiences to Billy Batson, an orphaned 12-year-old boy who, by speaking the name of the ancient wizard Shazam, is struck by a magic lightning bolt and transformed into the adult superhero Captain Marvel. Shazam's name was an acronym derived from the six immortal elders who grant Captain Marvel his superpowers: Solomon, Hercules, Atlas, Zeus, Achilles, and Mercury.
