Gore may not be the first thing to come to mind when most people think of Mike Mignola's long-running Hellboy comic series from Dark Horse, but the R-rating of Neil Marshall's film adaptation is a reminder that there are plenty of violent Hellboy moments in the comics. In order to fight monsters, you sometimes have to become a monster. Disturbing scenes are present even in ordinary superhero series, let alone horror comics like Hellboy. While Mignola's comics may emphasize atmosphere, there's no shortage of graphic imagery within their pages, from Hellboy's appearance on Earth during WWII to his apocalyptic fight with the Blood Queen to his adventures in Hell itself.
The most violent Hellboy scenes from Seed of Destruction to Hellboy in Hell and beyond certainly set the groundwork for Marshall's motion picture.
