Writer Don McGregor has earned acclaim in almost every genre comics has to offer, winning accolades and creating controversy with such legendary projects as Killraven and The Black Panther for Marvel Comics in the 1970s.That same decade, he pioneered the modern graphic novel with Sabre: Slow Fade of an Endangered Species, which predated by two months Will Eisner's famed A Contract with God. Continuing into the 2000s, McGregor has remained a vibrant contributor to comic books and syndicated comic strips, and has seen regular reissues of his landmark graphic novels and other works. McGregor broke into comics writing in 1971, penning character-driven horror and science-fiction stories for Warren Publishing's legendary, black-and-white comics magazines Creepy, Eerie and Vampirella. Earning an editorial job at Marvel Comics, McGregor continued in horror with Morbius, The Living Vampire (in the black-and-white magazine Vampire Tales) and in science fiction with Killraven / War of the Worlds in Amazing Adventures. He picked up superheroes with Luke Cage, writing that character's namesake series, and the Black Panther in Jungle Action, where he created a 13-part story arc one critic has called Marvel's first graphic novel. Establishing himself as the definitive Black Panther writer, he has revisited the character twice more, teaming with legendary artist Gene Colan in the 1980s on Panther's Quest in Marvel Comics Presents, and with Dwayne Turner in the bookshelf-format miniseries Panther's Prey in the 1990s.
In 1978, working with artist Paul Gulacy and with publisher Dean Mullaney of the startp Eclipse Books, McGregor created Sabre, the first graphic novel to be sold in comics stores. McGregor then created the beloved Detectives Inc. series of two graphic novels, and wrote short stories in Eclipse Magazine. In the 1980s, he created Ragamuffins for Eclipse Comics, Nathaniel Dusk for DC Comics and Alexander Risk for New Media Publishing. The following decade, he wrote the adventures of James Bond 007 and Zorro for Topps Comics, creating the breakout character Lady Rawhide for the latter. His artist colleagues, aside from those mentioned, have included Rich Buckler, Marshall Rogers, P. Craig Russell, Herb Trimpe and the late Billy Graham.
McGregor has also written two prose books: Dragonflame and Other Bedtime Nightmares (Fictioneer, 1978) and The Variable Syndrome (Fictioneer, 1981). As well, he wrote and directed a film version of Detectives Inc., which he later adapted as the second Detectives Inc. graphic novel.
In the 1990s, McGregor became one of the primary writers of the Zorro canon, with Topps Comics Zorro and his original creation Lady Rawhide; Image Comics adaptation of the movie The Mask of Zorro; two years of the syndicated Zorro, Papercutz's 2005 American manga-style Zorro comic-book series, later collected in a trade paperback.
