The recent trailer for Superman 2025 has unveiled a character called Baby Joey that took me by surprise. In a quick shot midway through the trailer, we see a green baby who has previously been identified as Joey, the son of Metamorpho. Unless you are as immersed in comic book lore as I am, you likely have no idea who he is. However, allow me to explain. Here’s everything you need to know about baby Joey, as depicted in the newest Superman trailer, which releases nationwide on July 11, 2025.
Who Is Baby Joey in DC Comics?

Joey made his debut in Justice League Europe #11 in 1990, where he was introduced as the son of Metamorpho, also known as Rex Mason and Sapphire Stagg. Joey Mason was born with mutant abilities that offer a unique variation of his father’s powers.
While Metamorpho has the ability to transform his body into nearly any element or compound, Joey takes this capability. He can manipulate the protonic structure of substances and convert one element into another. Sounds impressive. However, here’s the twist: Joey’s powers also apply to living organisms. This characteristic alone positions him as one of the more dangerous and unpredictable mutants within the DC Universe.
How Is Baby Joey Important in Superman (2025)?
Recently, a children’s book associated with the upcoming Superman movie, entitled Superman’s Friends and Foes, was published, revealing a significant hint regarding one of the film’s storylines. The book reveals that Lex Luthor kidnaps Baby Joey, placing Metamorpho in a difficult position, where he must choose between siding with Superman or bending to Luthor’s demands.
If you have viewed the trailer, you likely noticed that quick moment where Superman is holding a baby in one hand while Metamorpho clings to him during a rescue. That baby? Undoubtedly Joey. Although we do not precisely understand how Lex Luthor was able to get his hands on the child, it is evident that this kidnapping is being used as a means of leverage.
Another moment in the trailer shows Superman trapped in a cell, as Metamorpho seems to be synthesizing Kryptonite, presumably at Luthor’s command.
Indeed, Baby Joey could be a crucial element in this scenario. His protection may be essential for turning Metamorpho to oppose Lex and align with Superman. Based on the rescue sequence, it appears that Supes might successfully achieve this.
