Supervillain Origins: Metallo
A character dating back to 1942, he was originally introduced under a separate Golden Age incarnation. However, the character was completely re-invented for the Silver Age and re-introduced as journalist John Corben. A killer who experienced a car accident, he was found by an elderly scientist who replaced all of his body parts with metallic ones. Constantly requiring uranium to survive, he took on a crime streak, eventually seeking out the power of Kryptonite, butting heads with Superman in the process.
