Deathlok is a fictional character appearing in American comic books published by Marvel Comics. He first appeared in Astonishing Tales #25, created by Rich Buckler. At least three subsequent Marvel characters have used the “Deathlok” identity since then. A recurring theme among these characters is that a dead human has been reanimated with cybernetic technology. “Deathlok technology” has also been used thematically by Marvel writers in other stories.
