The Black Adam film is currently under development and its story in the comics is still ramping up. At "The Beginning of the End" which came from the Future State: Suicide Squad #1, Black Adam is about to have a child with an unlikely hero.
The following contains spoilers for "The Beginning of the End" which came from the Future State: Suicide Squad #1.
The heroic legacies within the DC Universe last for many centuries. The existence of the Justice Legion and the Legion of Super-Heroes of the distant future is living proof that heroism will remain alive and well in the future.
There are many things happening in the Future State but one interesting factor is a story with Black Adam having a child with the 853rd Century Wonder Woman. This sets up that there is a union between the DC's most powerful mystical heroes.
During the 853rd Century, the Justice Legion remained the most influential and powerful team in the history of the DC Multiverse. However, despite their sheer power, they are not prepared for the astounding power and ruthlessness of the Unkindness.
The Unkindness is a group of very powerful villains who turned the Seven Deadly Sins against the galaxy. This led to entire worlds getting wiped out. The Atlanteans, even Aquaman apparently got destroyed. Even the Man of Steel's final form, the Golden Superman, was overwhelmed to the point that he needed to fly back to the sun to heal.
The remaining members of Justice League were only Superman, Wonder Woman, Batman, and Flash of this era. They ended up flying to Kahndaq, which is currently a heavily fortified and protected, but the peaceful planet.
This era's Wonder Woman is a living statue who has been romantically involved with Black Adam for many centuries. In the years following the present day, Black Adam found peace and his world is becoming a paradise which has given the troubled people who need a fresh start.
During this era, Black Adam renounced magic and uses technology. The arrival of the Unkindness forced Black Adam to call upon the power of Shazam to thwart the villains.
Both Wonder Woman and Black Adam needed to retreat after Batman, Flash, and Superman were corrupted by the Sins. Black Adam later learned that Wonder Woman is pregnant with their child.
