Michael Moorcock's The Swords of Heaven, The Flowers of Hell

In 1979, Heavy Metal published this single-issue adaptation of Michael Moorcock's Eternal Champion mythos, with the author himself co-writing alongside Howard Chaykin, who also handled the art with colorist Mimi Maxwell. The story plunges the eternal warrior into a surreal, decadent world of psychic warfare and alien landscapes, capturing the psychedelic-meets-sword-and-sorcery energy of the magazine's golden age. Though brief, it stands as a unique collaboration between a fantasy literature giant and a comics master, bridging the gap between prose and sequential art.
