Licensing the magazine for America and renaming it Heavy Metal ( Métal Hurlant roughly translates as “howling metal”), he began by reprinting translated strips from the French magazine before branching out into original material. Heavy Metal is the legendary adult science fiction comic magazine, founded in 1977 by National Lampoon publisher Leonard Mogel, who started the magazine after discovering the French publication Métal Hurlant on a trip to Paris.
