John Corben was a mercenary working for Lex Luthor, during a smuggling campaign to Kaznia. Superman stopped him. In prison, Corben was diagnosed with a virus that would kill him. Luthor proposed to a plan to rescue him, but left out the details. And so, Corben woke up with his mind transplanted in an android body. He first sought revenge on Superman, but the Man of Steel revealed the origin of the virus: it was made by Luthor for the sole purpose of making a puppet out of Corben.
Corben struck out on his own, battling with an identity crisis and amnesia. He eventually found his way to Grodd's Legion of Doom. During a mission to Skartaris, he was captured by John Stewart and STRIPE. Before he could be questioned, something shut down his mind, and he was rendered in an inactive state.
- Android Physiology: After being infected with a virus, Corben's mind was placed in an android. An artificial skin was placed around the metal body and his eyes glowed green because of his kryptonite power source.
- Orozco's Retrovirus: In order to sway Corben to his side, Luthor infected him with a violent strain of Morozco's Retrovirus, for which no cure existed. The only alternative was to become a cyborg.
- Kryptonite Removal: Metallo is powered by the lump of kryptonite in his chest. Removing the kryptonite will cause him to power down.
- Kryptonite Cannon: Metallo could channel the radiation of the lump of kryptonite in his chest into a beam.
