Warren and Marvel
Sutton's first two comic-book stories appeared the same month. His first sale, "The Monster from One Billion B.C.", was published in Warren Publishing's black-and-white horror-comics magazine Eerie #11 (Sept. 1967), though it was originally commissioned for Famous Monsters of Filmland (where it was reprinted four months later). He also illustrated the five-page anthological Western story "The Wild Ones", written by Sol Brodsky, in Marvel's Kid Colt, Outlaw #137 (Sept. 1967). It was one of many Westerns he drew for the company, including the introduction of the short-lived feature "Renegades"—The Fugitive times four, in the Old West—in Western Gunfighters #1 (Aug. 1970).
As Sutton recalled his breaking into Marvel, editor-in-chief Stan Lee "...looked at the stuff that I had brought in, [which was] stuff that I had done in the service for Stars and Stripes in Tokyo. I think he was rather impressed by the fact that I had actually done a daily comic strip for two years. He didn't get many people who had done that. ... He just reached over and he pulled off this huge pile of blank paper. And he said, 'OK, do me a couple of Westerns and I'll see you next week. Have fun.' I remember that very well. 'Have fun.'[3]"
Sutton soon developed a trademark frantic, cartoony style that, when juxtaposed on dramatic narratives, gave his work a vibrant, quirky dynamism. That distinctive style helped establish the popular supernatural character Vampirella from her first story, "Vampirella of Draculona", written by Forrest J Ackerman, with costume design by artist Trina Robbins,[8] in Vampirella #1 (Sept. 1969).[9] Later, with writer Archie Goodwin, Sutton helped transition Vampi from cheeky horror hostess to serious dramatic character in the 21-page story "Who Serves the Cause of Chaos?" in issue #8 (Nov. 1970, reprinted in color in Harris Comics' 1995 Vampirella Classics series).[3][9]
Though well-suited to horror stories, Sutton was also admired for his work on such science fiction series as Marvel's Planet of the Apes magazine[10] and First Comics' Grimjack and Squalor, and for the humor title Not Brand Echh, on which he appeared in nearly every issue with parodies of Marvel's own characters.[9] He was not especially equipped to do superheroes, either by art style or temperament, once calling them "fascist".[11] While he lent a hand very occasionally, Sutton stayed mostly on Marvel's supernatural heroes: Werewolf by Night, Ghost Rider, and Doctor Strange (in the 1970s series, plus Baron Mordo backup stories in the 1980s Doctor Strange, Sorcerer Supreme). With writer Steve Englehart, penciler Sutton introduced the new furrily transformed X-Men character the Beast,[12]
A series in the 1970s black-and-white comics magazine Planet of the Apes, a licensed spin-off of the movie series, done with writer Doug Moench, was "recognized by many as Sutton's best", said comics historian and columnist Tom Spurgeon: "Together, they created the 'Future Chronicles' stories for Marvel's Planet of the Apes magazine. [For this] enormously elaborate and cleverly designed fantasy saga set on the world featured in the movies, Sutton worked with oversized originals to better show off his mixed-media work and allow for meticulous detail. The result was a lush, moody, and striking fantasy story to stand with any in mainstream comics history. ' He really made the work a joy, and pure fun,' Moench told [The Comics] Journal. ' This guy was so into the 'Future Chronicles', he wanted to put so much detail into it, he worked on these gigantic boards. It was [a] black-and-white [magazine], so it was already bigger than regular comics pages. Then he did that series twice up, these enormous things that would cover my desk. Right there it made it something special, the sheer physical size of it. The enthusiasm you could see in every brushstroke just made it so exciting'.[13]" For the horror-oriented Warren, Sutton drew dozens of stories early in his career. He moonlighted for Warren competitor Skywald Publications, drawing the Frankenstein-novel sequel "Frankenstein, Book II" (serialized in Psycho magazine #3–6, May, 1971 – May 1972)—using the pseudonym "Sean Todd" (writer-penciler Sutton and inkers Dan Adkins, Jack Abel and Sutton himself), to avoid the wrath of publisher James Warren. A separate story in Psycho #4, written by Sutton and drawn by him and Syd Shores, was credited as "Larry Todd" (writer) and "David Cook" (art).
For Skywald's short-lived line of color comics, Sutton wrote and drew stories for the Western title Butch Cassidy and the horror title The Heap (no relation to the 1940s–50s Hillman Periodicals character later revived by Eclipse Comics). He drew Marvel's similar muck-monster Man-Thing as eight-page installments in the omnibus series Marvel Comics Presents during the late 1980s.[9]
