John Corben just can’t catch a break. Every time the DC Universe resets he goes back to being a normal soldier. But time and time again he becomes Metallo. Emmett Vale was the first professor to take the fallen soldier and do something more with him. He stuck a piece of Kryptonite in his chest and turned him into a monster. A very interesting visual that the character still carries to this day. Corben becomes Metallo, the android with the heart of g…Kryptonite. Some comics depict him as an enhanced soldier with metallic appendages; some comics depict a horrific Terminator-like android. Metallo could be Amanda Waller’s answer to the newly resurrected Superman.
