"I don't believe Mr. Thawne is done with you yet."
—Metallo to Kara Danvers[src]

"Metallo" (died November 28, 2017) was a cybernetic servant of the Nazi military from Earth-X, specifically SS General Kara and Führer Oliver. He assisted their strike force during the attack on Earth-1.


At some point, an unidentified male individual from Earth-X (possibly the counterpart of John Corben) was transformed into Metallo, a cyborg 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-1 to help the generals take down the local superheroes. Metallo was extremely effective, instantly knocking out Kara Danvers with a single beam of Kryptonite radiation and Firestorm with a single punch.[1]

Metallo continuously assisted the Schutzstaffel leadership, stopping Felicity Smoak and Iris West when the two tried to help Kara escape from S.T.A.R. Labs and brought them to Führer Oliver.[2] Metallo later tried to stop some members of the Legends, Team Arrow, and Team Flash, who arrived to liberate S.T.A.R. Labs. However, he was overwhelmed by the powerful energy from their all-out attack and soon killed.[3]


Metallo appeared to be emotionless, rendered to nothing more than a machine, hardly acting any different than a robot.[1]

Crisis on Earth-X


  • Metallo's death is similar to that of The Pilgrim, as both were killed by a combination of various individuals' powers or abilities, being attacked from all sides all at once.
  • Having no noticeable human parts, yet still referred to as a cyborg, it is likely that Metallo's brain (or at least some parts of it) was still human.

Behind the scenes

  • In the 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, implying that the characters are counterparts.
