[From Dark Horse Comics: In the not-too-distant past, the first nuclear weapon test changed the world forever . . . but not in the way we expected. Unleashed upon the planet was a microscopic technological virus of unknown origin that infected millions -- some to no effect, some to horrifying agonies and disfigurement, others with the gift of incredible and sometimes terrifying power. But would a world populated by supermen become a battleground for good against bad . . . or bad against worse? Is it true that with great power comes great responsibility . . . or does it truly come with great license? Dark Horse Heroes Omnibus collects Comics Greatest World and Will to Power, the two hit maxiseries created by Dark Horse Comics that turned the concept of the superhero universe on its head, bringing together an all-star team of creators.] 
X Omnibus 1 (1-11, One Shot to the Head, story from Dark Horse Presents 19-20, Hero Illustrated Special 1-2; w Steven Grant et al.; a Doug Mahnke, Chris Warner, Jimmy Palmiotti, Tim Bradstreet, et al.). [From Dark Horse Comics: The city of Arcadia is the dark side of the American Dream. It's the land of opportunity, if you've got the money to buy it or the muscle to take it. The police are the best trained and equipped in the country, if you can afford their protection. Crime is under control, because crime is in control. For the corrupt and the ruthless, Arcadia is paradise on Earth. But a cold storm is blowing through the streets of Arcadia, a plague wind in black leather and torn cloth, a one-eyed, one-man judge, jury, and executioner whom the papers call "The X-Killer." He has set the new rules for Arcadia. Cross the line once, you'll receive a warning. Cross them twice, and X will mark the spot . . . where they'll find your body.
X Omnibus Volume 1 collects for the first time the audacious, critically acclaimed Dark Horse series that made "grim and gritty" superheroes seem like cuddly plush toys. Violent and morally ambiguous, X walks the thin line between heroism and obsession and shows that sometimes the cure may be worse than the disease. X Omnibus Volume 1 features over three hundred story pages by creators including Steven Grant, Doug Mahnke, Chris Warner, Jimmy Palmiotti and Tim Bradstreet.]
