For other uses of "Metallo", see Metallo.

Dr. Gilcrist (died late 2016), also known as Metallo, was a scientist working for Project Cadmus. He was later converted into a cyborg like John Corben with the mission to destroy the Kryptonians residing on Earth, only to be defeated by Superman and the Martian Manhunter.


Gilcrist was concerned with Corben's new condition, but his superior was confident, namely in his ability to destroy Kryptonians. After failing to do so, the Doctor ordered to have Gilcrist converted as well.

Later, Gilcrist terrorized Metropolis while Corben distracted Superman and Supergirl. Gilcrist later challenged Superman, who teamed up with Martian Manhunter and removed his "Kryptonian heart" after a hard battle, killing him.[1]

Powers and Abilities


  • Enhanced strength: As a cyborg, Gilcrist's strength was apparently able to match that of a Kryptonian, however, in his confrontation, against Superman who now had an anti-kryptonite suit and at full strength, was able to overpower Gilcrist easily. He was also able to leap across buildings in a single bound.
  • Kryptonite beam: Gilcrist was able to fire a green energy beam of Kryptonite radiation.
