Black Adam was an ancient Egyptian slave who received the powers of the Wizard Shazam. However, he was imprisoned for millennia by the Wizard after he misused his powers. He was eventually freed in the modern day where he went on to battle the Wizard’s new champion Billy Batson many times.
Origins : Ancient Egypt
Teth-Adam was a slave in Kahndaq, where almost the entirety of his family was killed by the dictators — all except his nephew Aman, whom Adam eventually managed to contact and help escape from imprisonment, being mortally wounded by guards in order to buy him time.
Aman, however, refused to abandon his dying uncle, and rescued him. Together, while escaping the underground prisons, they found themselves magically transported into the Rock of Eternity, where they were greeted by Shazam. The wizard, deeming Aman pure, offered him the role of his champion, giving him the task of freeing Kahndaq — which Aman accepted on the condition that Shazam healed Adam. Explaining that the gift bestowed upon him could be shared with his family, Shazam gave Aman his powers, healing and empowering Adam in the process.
Being returned to Kahndaq, Aman and Adam contemplated how to use their powers in order to free their people. While Adam was willing to destroy the dictators and exact revenge for their dead family, Aman wanted to save them and give them peace, stopping all bloodshed. Fearing that Aman’s method would not work, Adam killed him and seized his powers for himself, seeing it as a necessary sacrifice for the greater good.
Black Adam is known in legend for having defeated the dictators and the Seven Sins, successfully freeing Kahndaq. He also battled against an alien invasion, who had come to subdue Kahndaq and the rest of the World centuries before the modern day. Adam defeated their champion in single combat, provoking the other aliens to flee Earth.
Though myth says he merely disappeared, Black Adam actually turned against the Council of Eternity and murdered all its members but Shazam — the wizard, however, managed to overpower and seal Black Adam away.
The Frost King
In the 10th Century, an immensely powerful cryokinetic known as the Frost King arose, posing a threat to entire planet. In order to stop him, Hippolyta of Themyscira, an immortal Viking Prince, and an avatar of the Green came together. However, knowing that even with all their might they could not defeat the Frost King, they petitioned the Wizard Shazam, who reluctantly agreed to free his former champion Teth-Adam to aid them against the threat.
They traveled to Greenland, where the Frost King made his home. They fought a losing battle against the Frost King, losing the Avatar to his constructs and his frozen powers. They fled south, moving as many civilians as they could into a fortress for their protection. However, Adam remained behind, and, having located the Frost King’s human family, put them in his path, wagering that they would bring out the man that was once Edward Olafsson long enough that he could strike. Much to the disgust of his companions, his plan worked, at least to some extent. In the chaos, the Frost King’s family tumbled into a crevasse in the glacier below them, enraging Olaffson further. Frost King stabbed the Viking Prince through his chest, but the Prince, cursed with an eternal life save for a noble death, took the Frost King with him as he fell into the crevasse below.
Using his power, Black Adam sealed the crevasse, locking the Frost King away. With ice receding, the Green’s avatar, thought lost, was able to return. Combining their strength, Hippolyta, the Avatar, and the Wizard Shazam were able to return Black Adam to his tomb, despite Adam’s struggles.
Eventually, Black Adam was freed from his tomb through unknown means. He went on to become a recurring enemy of his former mentor’s new champion, and the champion’s adopted family.
He eventually married Adrianna Tomaz, who sought to soften his wrathful, often villainous edge. She was not entirely successful at the time, and eventually died fighting to protect Khandaq.
