Welcome to the first issue of the all-fun adventures of Billy Batson as the World's Mightiest Mortal, Captain Marvel! Thanks to a magical rift created when Captain Marvel battled Mr. Mind's monsters, 14-year-old Theo Adam has been returned to Earth from his banishment. But Theo has one problem: he can't remember the magic word that gives him the powers of Black Adam. There's only one solution: follow Captain Marvel and get the word out of his alter ego, 11-year-old Billy Batson.
