- The baby Superman is seen holding in the trailer is Joey Mason, the son of Metamorpho and Sapphire Thragg.
- Joey is a mutant with a different version of his father's powers, allowing him to alter the state of any material, including living beings, which makes him quite powerful.
- It appears that Lex Luthor has kidnapped baby Joey, which is why Metamorpho is helping him to capture Superman by creating Kryptonite.
Superman’s recent trailer introduced us to a character I genuinely didn’t expect to see. In one quick scene, we catch a glimpse of a baby who’s almost certainly Joey, the son of Metamorpho. Now, unless you’re as deep into the comic book trenches as I am, chances are you have no clue who he is. So, let me break it down for you. Here’s everything you need to know about baby Joey, as seen in the latest Superman trailer.
Who Is Baby Joey in DC Comics?
Joey made his first appearance in Justice League Europe #11 back in 1990 and was introduced as the son of Metamorpho/Rex Mason and Sapphire Stagg. Joey Mason was born a mutant with a unique twist on his father’s powers.
While Metamorpho can morph his body into virtually any element or compound, Joey takes it a step further. He can manipulate the protonic structure of materials and transform one element into another. Sounds cool, right? Well, here’s the kicker: Joey’s abilities extend to living beings as well. That alone makes him one of the more dangerous and unpredictable mutants in the DC Universe.
How Is Baby Joey Important in Superman (2025)?
Recently, a children’s book tied to the upcoming Superman movie, titled Superman’s Friends and Foes, was released, and it might’ve just dropped a major clue about one of the movie’s plotlines. The book reveals that Lex Luthor kidnaps Baby Joey, forcing Metamorpho into a tough spot, choosing between siding with Superman or bending to Luthor’s will.
Now, if you’ve seen the trailer, you probably caught that quick shot of Superman holding a baby in one hand while Metamorpho clings to him mid-rescue. That baby? Definitely Joey. And while we don’t exactly know how Lex Luthor managed to get his hands on the child, it’s clear that this kidnapping is being used as leverage.
Another trailer moment shows Superman trapped in a cell, while Metamorpho appears to be synthesizing Kryptonite, most likely under Luthor’s orders.
So yeah, Baby Joey might just be a major piece of the puzzle here. His safety could be the key to turning Metamorpho against Lex and getting him to side with Superman. And judging by the rescue scene, Supes might just pull it off.
