Harley Quinn Wiki

Metallo is a member of the Legion of Doom and a minor character on Harley Quinn. He is a radioactive cyborg intelligence who depends on Green Kryptonite as his energy source, making him an enemy of Superman.


In "L.O.D.R.S.V.P.", Metallo attended the party at the Hall of Doom when the Legion was choosing between Harley Quinn and KGBeast as the potential new members. However, he was stopped at the door due to not passing through the metal detector.

In "A Seat at the Table", Metallo applauded as Harley and her crew were officially welcomed into the Legion of Doom. He also attended the Legion's weekly pitch meeting where he along with the rest of the members voted to approve Joker's plan to build a giant tower with his face on it before Harley interjected and questioned his plan.
