Metalo was an enemy of Superman.

George Grant was a scientist who created a powered suit of metal armor and used it to challenge Superman after robbing a mail train. He was easily defeated, but returned many years later in an improved Metalo suit and with artificially acquired super strength, as well as a ray weapon which weakened Superman. The Man of Steel was able to restore his depleted strength to its former levels with an intensive training regime though, and defeated Grant again.



  • Metalo Suit: it was made with the strongest metal alloy known in that time.
  • Super Strength Serum: It could make the user super-strong and super-resistant.

  • This version of Metalo, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths event and later restored following the rebirth of the infinite Multiverse during the Dark Crisis of 2022-2023. Even though other versions of the character may have appeared, this information does not apply to those versions.
  • This version's name has only one "l".

The initial story showed Metalo unmasked, but he was never clearly identified as Grant (who was shown earlier in the story), and the image is in extreme long shot.
