When asked if Black Adam will ever fight Superman in the DCEU, Dwayne Johnson answered, “Absolutely. That is the whole point of this man.”

After so much time without Superman in the DCEU, plus all the uncertainty regarding the future of the franchise and what storylines will be canon going forward, a Superman vs. Black Adam fight would be a good start for Henry Cavil’s DCEU return.
Dwayne Johnson has promised that Black Adam will be the start of a new era for the DCEU and that it will change the balance of power in the franchise, and there is no better way to do it than have Black Adam fight Superman at some point. Black Adam is introducing the Justice Society of America, which suggests that some sort of DCEU retcon might happen to accommodate the existence of the JSA. Still, Black Adam is in the DCEU, which means a potential Superman vs. Black Adam fight can set up a new beginning for Henry Cavill’s Superman

So what do you think? Personally I’ll be very excited to see their face off!
