From 2000 to 2003, Jean-Marc Lofficier was editor and senior writer of a line of French comic books published by Semic Comics, redeveloping old French characters from the 1960s such as "Wampus", "Kabur", "Phenix", "Homicron", "Dragut" and "Dick Demon" into more modern versions, even gathering a number of them in the mini-series "Strangers" published by Image Comics in 2003. This universe of characters is now gathered as Hexagon Comics. The Lofficiers also wrote "Blood Oath" a crossover between Phenix and Top Cow's Witchblade. Starting in 2010, the Lofficiers started to reprint the "classic" stories from the 1960s and 1970s in a series of black & white trade paperbacks, as well as write new stories, mostly by relaunching the comic-book "Strangers". Since that date, Jean-Marc has been editor-in-chief of Hexagon Comics.
