Black Adam makes his return in Shazam! #28. Within these pages we learn that while Shazam gave Black Adam his powers, they came from different sources than Captain Marvel's!
The wizard Shazam reveals that Black Adam received his powers from Egyptian gods. Here are the gods and what powers they gave to Black Adam:
- Shu (god of air and supporter of sky) - Stamina
- Hershef (the Egyptian Hercules) - Strength
- Amon (king of the gods) - Power
- Zehuti (god of wisdom) - Wisdom
- Anpu (conductor of the dead) - Speed
- Menthu (god of war) - Courage
Notice they still spell out Shazam and they are the same powers (stamina, strength, power, wisdom, speed, courage) given to Captain Marvel.
Black Adam was given the same powers as Captain Marvel, but from different sources. And, as we learned in Marvel Family #1, he let these powers corrupt him and that ultimately led to his banishment by Shazam. (You can read about it here!)
