'A' is for Stamina, 'Z' is for Power!" Part 3 of 4. Guest-starring Black Adam (with his origin). Story by Roy and Dann Thomas. Art by Tom Mandrake. Captain Marvel has met his predecessor in battle and failed. Black Adam was wielding the power of the wizard Shazam 5,000 years before Billy Batson was even born. Can Billy find a way to defeat his foe, a being who can match his every move and then some? Perhaps the answer lies within the origin of Black Adam.
Note: The events in this mini series take place before Legends #1.
