and upon not receiving Code Authority approval, Marvel published the issues without the Code seal on their covers. The comics met with such positive reception and high sales that the industry's self-censorship was undercut, and the Code soon afterward was revamped. Another landmark in Kane's Spider-Man run was the arc "The Night Gwen Stacy Died" in issues #121–122 (June–July 1973), in which Spider-Man's girlfriend Gwen Stacy, as well as the long-time villain Green Goblin were killed, an unusual occurrence at the time. With writer Roy Thomas, Kane helped revise the Marvel Comics version of Captain Marvel, and revamped a preexisting character as Adam Warlock. Kane and Thomas co-created the martial arts superhero Iron Fist, and Morbius the Living Vampire. Kane and writer Gerry Conway transformed John Jameson, an incidental character in The Amazing Spider-Man series, into the Man-Wolf. Conway, Kane's collaborator on the death-of-Gwen-Stacy storyline and elsewhere, described Kane in 2009 as Pioneering new formats Kane's side projects include two long works that he conceived, plotted and illustrated, with scripting by Archie Goodwin (writing under the pseudonym of Robert Franklin): His Name Is... Savage (Adventure House Press, 1968), a self-published, 40-page, magazine-format comics novel; and Blackmark (1971), a science-fiction/sword-and-sorcery paperback published by Bantam Books and one of the earliest examples of the graphic novel, a term not in general use at the time. Howard Chaykin served as Kane's assistant during the production of Blackmark and would call Kane "the most influential male" in his life. Later career During the 1970s and 1980s, Kane did character designs for various Hanna-Barbera and Ruby-Spears animated TV series including The Centurions which he co-created with Jack Kirby. In 1974 he contributed to redesigning the obscure Marvel Comics character the Cat into Tigra, and three years later created the newspaper daily comic strip Star Hawks with writer Ron Goulart. The strip, which ran through 1981, was known for its experimental use of a two-tier format during the first years. During this decade he also illustrated paperback and record-album covers, drew model box art, and co-wrote, with John Jakes, the 1980 novel Excalibur! He drew the John Carter, Warlord of Mars series for Marvel beginning in June 1977. In 1971, Kane met Michel "Greg" Regnier, then the editor of French-Belgian comics anthology Tintin Weekly. He ended up creating a science fiction/fantasy tale called Jason Drum, about an astronaut stranded on a sword and sorcery world. The
