Grendel is a long-running series of comic books originally created by American author Matt Wagner. First published by Comico, Wagner later moved publication of the series to Dark Horse. Originally a noir comic in the style of European titles such as Diabolik, it has evolved into, in Wagner's words, a study of the nature of aggression. In 2009, Hunter Rose (the first Grendel) was ranked as IGN's 88th Greatest Villain of All Time.
