Early 2006 saw Grevioux form two comic book imprints, Astounding Studios and DarkStorm Studios. Grevioux's Astounding Studios imprint was to focus on all-ages titles such as Valkyries, Guardian Heroes and The Hammer Kid. The Darkstorm Studios imprint was a more mature line, including the books Alivs Rex, Skull and Guns and Uzan, The Mighty.
