After Black Adam, Is Zack Snyder's Justice League Actually Canon?
There actually might be a way to bring Snyderverse back to DCEU and Black Adam could even be the start of it.
Black Adam was originally supposed to start a new era for DCEU, different from the direction Zack Snyder set in his Justice League, the extended director's cut. This was how the movie was promoted, what Dwayne Johnson said about it and the official position of Warner Bros. frowned upon by many Snyder fans. But a closer look at Black Adam shows that the new phase for DCEU might actually be very similar to Snyderverse.
To get into details, the difference between the Justice League shown in theaters – and the official canon of DCEU – and Zack Snyder's 4-hour cut must be explained. While botha cuts focus on planet Apokolips and its inhabitants, only Snyder's Justice League brings in Darkseid, the tyrannical ruler of Apokolips and one of the most powerful supervillains in the DC Universe. The Snyder's cut also points out that Darkseid has plans to conquer Earth and is going to start very soon.
This is where Black Adam enters. The events of the movie are happening in a fantasy nation of Kahndaq, the people of which live under the oppression of Intergang, an organized crime syndicate armed with weapons and technology of extraterrestrial origin supplied by Darkseid's pals who are clearly eager to weaken Earth and its superheroes. Though it is never mentioned in Black Adam where Initergang got their weapons and gadgets from, one simple look at these will tell you the technology came from space. With the knowledge of the comic canon, it is safe to say Intergang is connected to Apokolips.
So how does it all make Snyder's director cut a canon for Black Adam? Recollecting that the theatrical cut of Justice League only barely mentioned Darkseid and Snyder's version actually showed he was getting ready to start the invasion of Earth, one would think that a good move for Darkseid would be to arm crime groups on Earth just to see how the superheroes on Earth operate and hopefully even weaken them before the invasion. This is exactly what we see in Black Adam – crime groups armed with extraterrestrial weaponry.
While this theory sounds a bit forced, this could be the way to let Zack Snyder implement his vision without canceling Black Adam should the famous director return to work on DCEU.
