|“||Oh, yes. I know who you are. Lois Lane and Clark Kent. Crusading writers for the Daily Planet. Well, you've both lucked into the ultimate story, this time. The story of Metallo! The man who's gonna kill Superman!!||„|
Metallo started his life as a simple criminal but became a much more powerful villain after having his body upgraded - due to his status as one of Superman's main enemies Metallo has appeared in many comics, TV series and videogames based around the franchise: some of the more famous examples are his appearances in the Superman animated series, the Justice League and Smallvile - he also appeared in The Batman series.
A professional conman, John Corben was fatally injured in a car crash. Professor Emmet Vale, a cybernetics specialist, found the dying Corben and transplanted his brain into a cyborg body powered by a chunk of Kryptonite. When Corben, renamed Metallo, awakened, Vale instructed him to kill Superman. Metallo turned on Vale and killed him, but nevertheless went to battle against Superman. After his defeat, he was captured by Lex Luthor, who tore the Kryptonite chunk out of his chest, seemingly killing him.
