Both the new Superman and Black Adam share the same respect and admiration for the late original Supes, but that same respect is going to put these two heroes into conflict as a new Justice League attempts to form for Dark Crisis.
At this point in his early career as Superman, Jon Kent is trying to etch out a path for himself whilst living up to the legacy of his father. Meanwhile, Black Adam and the original Superman viewed each other as equals among the Justice League. More than that, just a dozen issues before the Justice League's demise, Superman expressed that not only Black Adam has the potential to be a better hero than him, he wants Black Adam to be a better hero than Superman. Black Adam certainly did not take those words lightly, especially upon Superman's death. Those words must ring closer to his heart even more so now that Black Adam remains the only surviving member of the original Justice League heading into DC's Dark Crisis event. He is just as determined to live up to Superman's legacy as Jon is, but the storyline will see both having conflicting views regarding what that legacy should look like, especially as Jon Kent endeavors on crafting a new Justice League molded in his father's honor.
In a new interview with CBR, Dark Crisis writer Joshua Williamson teases the conflict that arises between Adam and Jon. Without giving away too much of his future plans for Dark Crisis, Williamson is able to confirm that Black Adam isn't going to be co-signing Jon Kent's new Justice League anytime soon because Black Adam "sees them as children. He doesn't believe that even the members who have experience have what it takes to be considered the Justice League. There's a scene later where he flat-out tells them that they're lost in the shadow of the League. He does not believe in them. He has no faith in their abilities, and he feels that they are incapable of stepping up."
This arc has the potential to be fascinating, not to mention relatable to some audiences. As most readers will understand, everyone mourns differently. With Batman, Superman, and Wonder Woman confirmed dead along with the other leaguers, every hero will have a different reaction. This is one of those cases between Black Adam and Superman. This is especially interesting because neither is necessarily in the wrong. While it's understandable for Jon Kent to form his own Justice League to honor the fallen heroes and fill a void in a world that needs a superteam of heroes, Black Adam's reasons for opposing it aren't exactly illogical. It's easy to see Black Adam's concerns when the bulk of the new members are inexperienced.
There are plenty of ways this storyline could go. It could prove to be an opportunity where Superman and his new Justice League ultimately wind up proving Black Adam wrong through their success, or Black Adam could be proven right by showcasing the new League failing miserably. This also begs one to wonder how Superman and Black Adam could learn to co-exist or compromise with each other regarding the legacy of the Justice League, but readers will have to wait to see how DC's Dark Crisis event plays out to find out.
