"When Billy Batson speaks the name of an ancient wizard, he is magically transformed from boy to man
-- the world's mightiest mortal!"
That name is
Shazam and he becomes Captain Marvel.
The SHAZAM story started in 1939 and apparently as of 1994 was still going... I should note however that I have never seen a SHAZAM
comic, I have seen the odd Captain Marvel
toy in stores, and I only know the name because my
Uncle used to dress up in a
cape and try to fly off the
coffee table (according to my
mother).
