Shazam

(You may be looking for a different Captain Marvel.) When nine-year-old Billy Batson met a kindly old wizard, he was given the wisdom of Soloman, the strength of Hercules, the stamina of Atlas, the power of Zeus, the courage of Achilles, and the speed of Mercury. By channeling the power of these six Greek Gods and shouting the first letter of each of their names, "SHAZAM!," Billy Batson is transformed into Captain Marvel, The World's Mightiest Mortal!
