Rich Buckler was an American comics artist and penciller, best known for his work on Marvel Comics' Fantastic Four in the mid-1970s and for creating the character Deathlok in Astonishing Tales #25. Buckler drew virtually every major character at Marvel and DC, often as a cover artist.

Deathlok is the name of several fictional characters appearing in American comic books published by Marvel Comics. The first Deathlok, Luther Manning, appeared in Astonishing Tales #25, created by Rich Buckler. At least five subsequent Marvel characters have used the "Deathlok" identity since then: Michael Collins, Jack Truman, Rebecca Ryker, Henry Hayes, and Jemma Simmons. 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.
