Holy Terror is a 2011 graphic novel by Frank Miller which follows a costumed vigilante named The Fixer as he battles Islamic terrorists after an attack on Empire City. The novel was originally proposed as Holy Terror, Batman! in 2006 but is no longer a project associated with the Batman character or DC Comics. Miller explained in 2010: "It's no longer a DC book. I decided partway through it that it was not a Batman story".
