6. The Atomic War
(Captain Marvel Adventures #66)
Hey, look, a Captain Marvel imaginary story! We don’t get so many of those.
In this one, Billy Batson goes into work to report the news over the radio. As he’s doing his thing as an eleven-year-old boy who is somehow an accredited reporter, his boss bursts in with a new report: Chicago’s been destroyed with a nuclear warhead. Oops. Billy shouts his magic word SHAZAM and transforms into Captain Marvel so he can fly to Chicago and help.
He pulls a woman from her house, but she’s already dead from radiation burns. Captain Marvel decides to head back to Fawcett City to report on the tragedy, but he spots a flood of atom bombs on the way. He tries to stop one, but fails, and it blows up. When he does get back, he tries to inform everyone that they need to get out of the major cities, but Whiz Station is struck by a bomb, killing everyone but him. He eventually finds like five dudes just a-firing missiles in literally every direction to…destroy the world, I guess.
But, hey, it was just a fake TV broadcast Billy did to warn America about the dangers of nukes. This one is less fun than that story about Superman becoming two other Supermans.
