Metallo (Earth-X)


 * For his Earth Thirty-Eight equivalent, see John Corben. For other uses of "Metallo", see Metallo (disambiguation).

"Metallo" was a cybernetic servant of the Nazi military from Earth-X, specifically the SS general Kara and Führer Oliver. He assisted their strike force during the attack on Earth One.

Biography
At some point, a male individual from Earth-X, with a voice strikingly similar to that of John Corben of Earth Thirty-Eight, was transformed into Metallo, powered by a Kryptonite core. He was used as part of the SS strike force of the New Reich, led by Führer Oliver and general Kara. Metallo was sent to Earth One to help the generals take down the local superheroes. Metallo was extremely effective, instantly knocking out Kara with a single beam of Kryptonite radiation and Firestorm with a single punch.

Metallo continuously assisted the Schutzstaffel leadership, stopping Felicity Smoak and Iris West when the two were snooping around the occupied S.T.A.R. Labs, before bringing them to Führer Oliver. Metallo later tried to stop some members of Legends as well as of Team Arrow and Team Flash, who arrived to liberate S.T.A.R. Labs, but was overwhelmed by their all-out attack, in a manner similar to the death of The Pilgrim and was killed.

Personality
Metallo appeared to be emotionless, rendered to nothing more than a machine, acting hardly different than a robot.

Behind the scenes

 * In DC Comics continuity Metallo debuted in Action Comics #252 (May, 1959) and was created by Robert Bernstein and Al Plastino. He frequently appears as an enemy of Superman and he is mostly known for his cybernetic body parts and the Green Kryptonite he uses as an energy source.
 * This version of Metallo has visual similarities both to most of the character's appearances in the comics, and also to Grid, an evil living computer program created from Cyborg's systems that became a member of the "Crime Syndicate", a team of villainous counterparts of the Justice League, similar to Earth-X's SS generals being Nazi-affiliated superheroes.
 * This version of Metallo is voiced by Frederick Schmidt, who portrayed John Corben on Supergirl, meaning that the characters are doppelgängers. In Crisis on Earth X Part 4 Vixen said that Earth X Metallo is like the Terminator from the movie Terminator when she saw him attack her and her friends and her sister who were on her team in Star Labs fighting Earth X Metallo from Earth X.
