Omar Devone Little is a fictional character on the HBO drama series The Wire, portrayed by Michael K. Williams. He is a notorious Baltimore stick-up man, frequently robbing street-level drug dealers. He is legendary around Baltimore for his characteristic duster under which he hides his shotgun, large caliber handgun and bulletproof vest, as well as for his facial scar, and his habit of hauntingly whistling "A-Hunting We Will Go" when stalking the streets. When people see or hear him approaching, they run away and will often warn others by shouting "Omar comin'!" Omar has a strict moral code, which involves refusal to harm innocent people or use profanity, setting him apart from other street-level characters. Also his homosexuality and privately tender nature are in obvious contrast with typical notions of machismo attached to violent criminals. He also cares for his grandmother and is seen escorting her to church on Sunday mornings.
