Given powers by an ancient and mysterious wizard, boy reporter Billy Batson need only say the word Shazam and he is transformed into the powerful adult hero Captain Marvel. Reprinting the early 1940s tales of the World's Mightiest Mortal, this beautiful book includes classic stories in which Captain Marvel battles the heavyweight boxing champion and his super-intelligent gorilla companion, breaks up a murderous gambling ring, investigates curious occurrences at a haunted house, fights a deadly ancient vampire, breaks up a cattle rustling ring, meets his match in a robotic adversary and fights his hypnotized ally Spy Smasher.
