Rich Buckler (February 6, 1949 – May 19, 2017) was an American comic book 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.
As a teenager in Detroit, Buckler attended the initial iterations of the Detroit Triple Fan Fair, eventually running the convention along with originator Robert Brosch in 1969–1970.
Buckler's first comics work was as a teenager with the four-page historical story "Freedom Fighters: Washington Attacks Trenton" in the King Features comic book Flash Gordon #10 (cover-dated Nov. 1967). At DC Comics, he drew the "Rose and the Thorn" backup stories in Superman's Girl Friend, Lois Lane #117-121 (Dec. 1971 - April 1972).
Buckler drew the first three issues of writer Don McGregor's Black Panther series in Jungle Action vol. 2, #6-8 (Sept. 1973 - Jan. 1974), a run that Comics Bulletin in 2010 ranked third on its list of the "Top 10 1970s Marvels". He fulfilled a decade-long dream in 1974 when assigned to draw Marvel's flagship series, Fantastic Four, on which he stayed for two years. During this period, Buckler created the cyborg antihero Deathlok, who starred in an ongoing feature debuting in Astonishing Tales #25 (Aug. 1974).
