Omar Devone Little is a fictional character on the HBO drama The Wire, portrayed by Michael K. Williams. Omar is a notorious Baltimore stick-up man, frequently robbing street-level drug dealers. Omar holds several unique characteristics that are likely responsible for his viewer popularity, including: his strict personal morality whereby he both refrains from harming innocents and from using profanity (which also ensures his independence from most other street-level players); his characteristic face scar and use of a shotgun; his homosexuality and privately tender nature, held in obvious (and subversive) contrast from typical notions of masculinity attached to violent criminals; and his use of haunting whistling as presage to his wrath. Central throughout Omar's trajectory is his steady descent into intractable conflict with both the Barksdale and Stanfield organisations, in both cases initiated by his robberies. Omar is also noted for his close relationships with his partners, and with his guardian and ad hoc banker Butchie. The character is based on Baltimore area robber and hitman Donnie Andrews.
Baltimore Department of Social Service records illegally obtained by the Barksdales claim that Omar Little was born on February 11, 1982. If accurate, this would make him 20 years old at the beginning of the series, though he appears older (and probably is, based upon his career information below). Omar was orphaned at a young age, and raised by his grandmother Josephine, who is largely responsible for his strict moral code, despite his criminal occupation. He attended Edmondson High School in West Baltimore, a few years behind Bunk Moreland. For more than ten years, Omar has made his living holding up drug dealers, and staying alive "one day at a time." He is legendary around Baltimore for his characteristic shotgun, trench coat, facial scar, and whistling "The Farmer in the Dell", or "A Hunting We Will Go" when stalking the streets. Every time people see or hear him coming they run, even the children. He repeatedly demonstrates exceptional skill at surveillance and as a stick-up man and shooter, further contributing to his feared status as an efficient professional. He is highly intelligent and cunning, consistently executing well-laid plans, anticipating moves, and outsmarting his adversaries with effective strategic planning. Once a month, he accompanies his elderly grandmother to church. He has a brother, "No Heart" Anthony, who is incarcerated for a jewelry store robbery in the early '90s. Omar has a fondness for Newport cigarettes and Honey Nut Cheerios, though several episodes indicated that he often had difficulty in locating the latter. He often carries a shotgun or large caliber handguns in .44 Magnum (Desert Eagle or Colt Anaconda), .45 ACP semi-automatics, and .50 Action Express.
