Dwayne Johnson is already working on the future of Black Adam

There is no way that Johnson would let his "once in a lifetime" character end with just one movie. Black Adam's next appearance A movie featuring Black Adam versus the JSA would be interesting.

Johnson hasn't been shy about teasing fans regarding his future in the DCEU. However, neither he nor director Jaume Collet-Serra has confirmed anything at this point. DCEU is still without a president after Walter Hamada stepped down from the role.

Regardless, Johnson has given us some clues about his future as Teth-Adam. During the post-credits for Black Adam, Amanda Waller warned the anti-hero that she will not hesitate to "call in a favor" in case he leaves the city of Kahndaq. The favor Waller was talking about is Henry Cavill's Superman.

We know Black Adam will not heed Waller's warning and this will set up an eventual confrontation with the Man of Steel. This may happen in the sequel to Cavill's Superman movie which is reportedly in pre-production.

It may also be the central plot of a Black Adam sequel. It wouldn't be hard to imagine a plot where Black Adam has some important reason to leave his beloved city but is stopped by Superman in the process. The two duke it out until they are interrupted by some other powerful being and they end up working together to stop a catastrophe from happening.

Johnson also teased that Black Adam will eventually fight Shazam at some point. It may be a third Shazam film or a cross-over movie similar to Batman vs Superman that will gather Earth's mightiest metahumans.

Black Adam could also be part of a stand-alone Justice Society of America movie. Fans have been loving the JSA in Black Adam and are eager to explore more of the characters. It might be a good opportunity for Johnson to appear as the anti-hero once again.

The other big movie is the fan-requested Justice League sequel (the Snyderverse one). Fans have been speculating that DC intends to continue the Snyder version of the Justice League now that Henry Cavill is back as Superman. If Darkseid returns as the main villain, then even Black Adam needs to pitch in to stop the warlord.

There could be a number of ways that DC can work on in order to help Black Adam be one of the central figures in the DCEU as several projects are currently in development. The only thing that the studio needs right now is to appoint a president to lead DC into the next phase.

As Johnson has mentioned numerous times, this is the "new era " of the DCEU.
