Doc Stearn...Mr. Monster Doc Stearn...Mr. Monster is a fictional character comic book superhero created by Michael T. Gilbert, most recently published by Dark Horse Comics. The character first appeared in Pacific Comics "Vanguard Illustrated" #7 (July 1984). Later the character graduated to his own monthly series "Doc Stearn...Mr. Monster" from Eclipse Comics. Mr. Monster was derived from an old 1940's character created by Fred Kelly who appeared only twice in 1940s Canadian comic books ("Triumph Comics" #31, 1946, and "Super-Duper Comics" #3, 1947). After trademarking Mr. Monster, Gilbert heavily revised the character creating a Horror/Humor hybrid which often featured heavy satire of both the horror genre and superhero comics in general.
