Marvel says: "You're digging him in this month's issue of DEADPOOL and you want to know more about him?  How about his origin story? A troubled soul, set upon a path of vengeance he does not understand.  An assassin without equal, trained in the most secret of killing techniques.  A flesh and blood specter, haunting the killers of the world.  A monkey...with a gun.  Bear witness as the legend is born.  Hitman Monkey."
