Metallo

John Corben was a ruthless criminal whose dying body was saved by a scientist who transplanted his brain into a powerful robotic shell powered by Kryptonite — making him both virtually indestructible and a deadly natural threat to Superman.

Few villains in the DC Universe carry as much iconic weight as Metallo, who crashed onto the scene in Superboy #85 in 1960, the product of Silver Age masterminds Jerry Siegel and George Papp. A fixture of Superman's rogues' gallery across an extraordinary span stretching all the way to 2026, this enduring threat has haunted the pages of Superman, Action Comics, and Adventures of Superman for over six decades. Metallo keeps dangerous company — sharing stories with Superman, Lex Luthor, Lois Lane, and Clark Kent — which tells you everything about the high-stakes corner of the DC universe this character calls home. If you're building out your Superman collection, Metallo is an absolute must-know name.
