Rex Mason

Rex Mason was a daring soldier-of-fortune and adventurer who, while on a mission in Egypt, was exposed to a mysterious radioactive meteor fragment called the Orb of Ra. The strange energies transformed him into Metamorpho, the Element Man — able to transmute his body into any chemical element or compound found in the human body.

Born in the Silver Age pages of The Brave and the Bold #57 in 1964, Rex Mason is one of DC Comics' most distinctive and enduring creations, conjured into existence by the inventive team of Bob Haney and Ramona Fradon. Over six decades of publication history — stretching all the way to 2025 — he's proven himself far more than a curiosity, accumulating 201 catalog appearances, seven of which carry genuine key-issue weight for collectors. His adventures have unfolded across Metamorpho, Justice League Europe, and the anthology title that first introduced him to the world, and along the way he's shared the page with some of DC's heaviest hitters: Batman, Superman, and The Flash. That kind of company speaks for itself — Rex Mason belongs to the Silver Age's most imaginative tradition, and any fan with a taste for the weird, wonderful, and genuinely original owes it to themselves to seek him out.
