Designed to compete with DC Comics' successful launches of House of Mystery and House of Secrets, Tower of Shadows, like its companion comic Chamber of Darkness, sold poorly despite the roster of artists featured. After its first few issues, the title, published bimonthly, began including reprints of "pre-superhero Marvel" monster stories and other SF/fantasy tales from Marvel's 1950s and early 1960s predecessor, Atlas Comics. After the ninth issue, the title changed to Creatures on the Loose, and the comic became a mix of reprints and occasional sword and sorcery/SF series. "At the Stroke of Midnight", writer-artist Jim Steranko's lead story in the premiere issue, won a 1969 Alley Award for Best Feature Story. Its creation had led to a rift between the celebrated Steranko and editor Lee that caused Steranko to stop freelancing for Marvel, the publisher that had showcased his highly influential work. Lee had rejected Steranko's cover, and the two clashed over panel design, dialog, and the story title, initially "The Lurking Fear at Shadow House". According to Steranko at a 2006 panel and elsewhere, Lee disliked or did not understand the homage to horror author H. P. Lovecraft, and devised his own title for the story. After much conflict, Marvel and freelancer Steranko parted ways. Lee phoned him about a month later, after the two had cooled down, and Steranko would return to produce several covers for Marvel from 1972 to 1973. In a contemporaneous interview, conducted November 14, 1969, Steranko reflected on the tiff: A Lovecraft story, "The Terrible Old Man", appeared two issues later, adapted by writer Roy Thomas and penciler Windsor-Smith. Additionally, Thomas and Tom Palmer – a renowned inker in a rare example of his penciling and inking – adapted the Lovecraft story "Pickman's Model" in issue #9. Marvel also published the all-reprint Tower of Shadows King-Size Special #1.
''Creatures on the Loose''
Retitled Creatures on the Loose with issue #10, this version led off with a seven-page King Kullsword-and-sorcery story by Thomas and artist Bernie Wrightson. The book included new stories by artists Herb Trimpe in #11, Syd Shores in #12, and Reed Crandall in #13, then became all-reprint until issue #16. There, writer Thomas and the art team of Gil Kane and Bill Everett introduced the feature "Gullivar Jones, Warrior of Mars", starring an interplanetary Earthman created by author Edwin L. Arnold in his 1905 book . Following another issue by Thomas and one by Gerry Conway, science fiction novelistGeorge Alec Effinger wrote the final three installments. Effinger continued as writer for the series that immediately followed, in issue #22 : "Thongor! Warrior of Lost Lemuria!", adapting a sword-and-sorcery barbarian character created by author Lin Carter. Following writers Tony Isabella and Gardner Fox, Carter himself co-wrote the final two installments. Thomas, Marvel's associate editor at the time, recalled in 2007 that Thongor had been the company's first choice when Marvel decided to published a licensed fantasy character, rather than the eventual hit Conan the Barbarian. Publisher Martin Goodman "authorized us to go after a character. I first went after Lin Carter's Thongor, who was a quasi-Conan with elements of John Carter of Mars, partly became editor-in-chief Stan Lee liked that name the most ... I soon got stalled by Lin Carter's agent on Thongor, and I got a sudden impulse to go after Conan". The title's last series, "Man-Wolf", starred John Jameson, the werewolf son of Spider-Mansupporting character J. Jonah Jameson. It ran from issue #30–37. Its writers were Doug Moench, Isabella, and David Anthony Kraft, with art by pencilersGeorge Tuska and George Pérez. The series depicted Jameson as a god to an alien race. The series was finally finished years later in Marvel Premiere #45–46.
