As Captain Marvel, Billy thwarts a plan by Theo Adam and his employer, the rich tycoon Doctor Sivana, to destroy the WHIZ radio building and silence a witness to Adam's murders. Adam's encounters with Marvel, who is the "spitting image of C.C. Batson", along with the clues from the expedition, lead him to realize he is the reincarnation of Teth-Adam, the original heir to the power of Shazam. Upon crossing the Wizard, Teth-Adam was killed and his powers drawn into a scarab, the very same scarab that Adam stole from the tomb after killing the Batsons. Taking the scarab from Sivana's trophy room, Adam says the Wizard's name and is struck by magic lightning, becoming Black Adam.
