Joseph "Joey" Stagg is the son of Sapphire Stagg and Rex Mason, the superpowered adventurer known as Metamorpho. He had powers similar to Metamorpho except he can turn any object into any element, instead of turning himself into any element. At birth he turned the doctor and the midwife into mercury. As a baby he was raised by machines until Simon Stagg could find a way to cure his grandson. However, it wasn't Simon who would lead to Joey's loss of power, but his father's former crime-fighting partner, Element Girl. Believing to have found a way to cure them all with the Orb of Ra, Element Girl was actually killed in the process. However, since the meteor transforms those who touch it and Joey transforms the things he touches, the two naturally cancelled each other out. Joey was cured of his condition and the meteor was rendered inert. Joey now lives with his mother, Sapphire.


Joey was created by Keith Giffen for his Justice League Europe series.
