With James Gunn’s Superman right around the corner, fans are already brushing up on their DC Comics lore before it arrives. After spotting Baby Joey in the recently dropped trailer, fans have started theorizing about how he ties in with the plot. Furthermore, many are curious to know whether he is the son of the DC supervillain Brainiac.
Here’s everything you need to know.
No, Brainiac is not the father of Baby Joey.
In DC Comics, young Joseph Mason, otherwise known as Baby Joey, is the son of the metahuman superhero Metamorpho (Rex Mason) and Stagg Enterprises CEO Simon Stagg’s daughter Sapphire Stagg. Unlike his father’s ability to transmute his own body to other elements, Joey’s power allows him to perform molecular reconstruction on other things. This makes him an extremely powerful entity.
Baby Joey’s appearance in the trailer for Superman (2025) implies his involvement will be important in the movie’s plot. Fans believe that the supervillain Lex Luthor may have kidnapped Joey to use him to leverage Metamorpho for his powers, that perhaps will allow him to turn into kryptonite and take down Superman more easily. However, we have to wait for the movie’s arrival to check whether this theory holds true.
Popular insider ViewerAnon has recently confirmed that Brainiac will not feature in the movie. “No, none of that stuff – Brainiac, Waller, Sam Lane – is in the movie. And I’ve been told directly that there is no post-credit Brainiac tease or anything of the sort,” they stated.
ViewerAnon has previously dropped several leaks and spoilers on other franchises and movies. So, fans consider them to be a credible source of information. Having said that, the statement can be taken with a grain of salt since it is not an official report. For now, we can only wait for the movie’s release to confirm such details. Superman hits the theaters on July 11, 2025
