Whiz Radio, Shazam - Wizard, Marvel Family
Billy Batson's parents were archeologists. On a trip to Egypt C.C. and Marylin, along with Mary (Billy's twin sister), were seemingly all killed in mysterious circumstances. In truth, Theo Adam killed his parents and sent his sister back to the United States for adoption. Billy was entrusted to his uncle Ebeneezer, who took his inheritance and kicked him out on the street. Then, one day he was guided by a strange man to an abandoned subway tunnel deep within the bowels of the city. There he met Shazam, an old wizard who had fought against evil for more than 5000 years. Since Shazam was about to die he wanted to leave his power to another person, and had chosen Billy. He would give Billy his power in exchange for his pledge to use it for good purposes.
Billy said the word for the first time, and thus was born Captain Marvel. With the wisdom of Solomon, the strength of Hercules, the stamina of Atlas, the power of Zeus, the courage of Achilles and the speed of Mercury a young wide eyed Billy bacame one of "Earth's Mightiest Mortals" with powers spawned directly from the gods.
Billy became child radio announcer for WHIZ radio and through them and their spelling bee he met Freddy Freeman and his Twin Sister Mary. Since reuniting with his sister Mary, Billy has become very protective of her. Billy chose to split his power among himself, his sister Mary and both then subsequently donated a fraction of their power to their friend, Freddy Freeman, who was crippled when he accidentally stumbled onto a battle between the Marvels and one of their foes.
Freddy can summon the power, but unlike Billy or Mary, and due to the source of his power, Freddy speaks the name "Captain Marvel" to be transformed. The group is loosely referred to as "The Marvel Family" when all three are in their super-powered forms. Together, as Captain Marvel, Mary Marvel, and Captain Marvel, Jr, the Marvel family protected Fawcett City and Earth from numerous threats. Billy values his new "Marvel Family" very much, as it is the only real family he has.
Recently, The Marvels suffered a tremendous loss when the nefarious Mr. Mind detonated an atomic bomb in nearby Fairfield, killing thousands. Together, the Marvels brought Mr. Mind to justice, but the three nearly died when they were in a car accident in their non-powered forms. When their longtime enemy Black Adam reappeared, apparently to take their places, the one, true, original Captain Marvel ultimately defeated him.
Captain Marvel joined the Justice League for a while, even when Guy Gardner wouldn't stop teasing him, but left after a while. More recently, during the One Million incident, it was revealed that Billy will assume the wizard Shazam's role in the 853rd century. Billy's exploits up until that time remain unrevealed.
