In the trailer for "Black Adam," Dwayne "the Rock" Johnson's title character fights off all manner of obstacles — manmade and superhuman — and in the end, after seemingly besting all opponents, says, "There's no power on this planet that can stop me."
That may be true. But he didn't mention powers from other planets.
During the "Black Adam" end credits, Krypton's very own Superman (played by Henry Cavill) makes a dramatic entrance: The Man of Steel descends after Black Adam is visited, via drone, by Viola Davis' Amanda Waller. The pair's confrontation with Black Adam is almost a good-cop/bad-cop scenario, as Waller issues a not-so-veiled threat to Black Adam not to leave his home country of Kahndaq, while Superman just wants to talk.
