Adam and Captain Marvel battle each other on the grounds of the Sivana-funded Fawcett World Fair, with Marvel winning the battle by snatching Adam's scarab from him. Marvel takes Adam to the Wizard, who takes Adam's voice and wipes his memory. Billy later learns that the stranger who led Billy to the Wizard was the spirit of his father, and that his sister Mary is still alive. Billy promises, as Captain Marvel, to fight injustice and evil, and also to find his missing sister. Meanwhile, Sivana has lost all of his money and possessions due to the destruction of his properties by Marvel and Adam, and swears revenge on the Captain.
