Frank Frazetta, an illustrator of comic books, movie posters and paperback book covers whose visions of musclebound men fighting with swords and axes to defend scantily dressed women helped define fantasy heroes like Conan, Tarzan and John Carter of Mars, died on Monday in Fort Myers, Fla. He was 82.

The cause was complications from a stroke, said Rob Pistella and Stephen Ferzoco, Mr. Frazetta’s business managers.

Mr. Frazetta was a versatile and prolific comic book artist who, in the 1940s and ’50s, drew for comic strips like Al Capp’s “Lil’ Abner” and comic books like “Famous Funnies,” for which he contributed a series of covers depicting the futuristic adventurer Buck Rogers.

A satirical advertisement Mr. Frazetta drew for Mad earned him his first Hollywood job, the movie poster for “What’s New Pussycat?” (1965), a sex farce written by Woody Allen that starred Peter Sellers. In 1983 he collaborated with the director Ralph Bakshi to produce the animated film “Fire and Ice.”
