Metallo is a recurring villain in DC Comics, primarily known as an adversary of Superman. He is typically portrayed as John Corben, a former petty criminal who is severely injured, often in a car accident or other violent event. This injury leads to his body being reconstructed with cybernetic parts, including a power source of Kryptonite.

This Kryptonite heart serves as Metallo's primary weapon against Superman, as the radiation weakens the hero. Metallo's cybernetic enhancements also grant him superhuman strength, durability, and the ability to launch Kryptonite radiation attacks. His abilities and origin story have been modified over the years, but the core concept of a cyborg powered by Kryptonite remains consistent.

Over the years, Metallo has been a member of various supervillain teams and organizations. He consistently returns as a dangerous threat to Superman and Metropolis, representing the ever-present danger of Kryptonite and the potential of technology in the wrong hands.
