Malik "Poot" Carr is a fictional character on the HBO drama "The Wire", played by actor Tray Chaney.
 Poot starts out as a drug dealer in the Barksdale Organization who slowly rises through the ranks.
 He eventually ends up leaving the drug trade after its violent nature causes the death of his best friend Bodie Broadus and many other of his friends.
 He has the distinction, along with Wee-Bey Brice, Omar Little, Bubbles and Proposition Joe, of being the only characters in the drug trade to appear in every season.
D'Angelo "D" Barksdale is a fictional character on the HBO drama "The Wire", played by Larry Gilliard Jr. D'Angelo is the nephew of Avon Barksdale and a lieutenant in his drug dealing organization which controls most of the trade in West Baltimore.
 The immorality and ruthlessness of the drug trade gradually wears on his conscience, bringing him into conflict with the Barksdale leadership, most notably Stringer Bell.
Joseph Stewart, better known as "Proposition Joe" or "Prop Joe", is a fictional character on the HBO drama "The Wire", played by actor Robert F. Chew.
 Joe was an Eastside drug lord who preferred a peaceful solution to business disputes when possible.
 He was responsible for creating the lucrative New Day Co-Op with Stringer Bell, supplying much of Baltimore with heroin brought into the city by "The Greeks".
 Joe was a portly and amiable presence, but was often a match in wits for rival drug lords Avon Barksdale and Marlo Stanfield, and was able to manipulate most situations to his advantage.
 His nickname stemmed from his trademark phrase "I've got a proposition for you", going back to his days selling test answers on the school yard.
 Along with Poot Carr, Wee-Bey Brice, Omar Little, and Bubbles, he is one of the few characters from the drug trade to appear in every season.
Namond Brice ( ) is a fictional character on the HBO drama "The Wire", played by Julito McCullum.
 Namond is the son of Wee-Bey Brice and De'Londa Brice and is a middle school student during season 4.
 He is friends with Michael Lee and Randy Wagstaff and often bullies Duquan "Dukie" Weems.
 Namond lives with his mother and the two are well looked after by money from the Barksdale drug dealing organization that his father was a part of.
 Wee-Bey is serving consecutive life sentences for multiple homicides committed on behalf of the Barksdales, having even confessed to crimes he did not commit.
 Grateful because Wee-Bey shielded the rest of the organization by taking the prison sentence on himself, the Barksdales provide for Namond and De'Londa.
 Even after the organization is shattered by the incarceration of Avon Barksdale, his sister Brianna Barksdale continues to pay them.
 This steady income means that Namond is much better off than his peers.
Marlo Stanfield is a fictional character on the HBO television drama "The Wire", played by actor Jamie Hector.
 Stanfield is a young, ambitious, intelligent and extremely ruthless player and is head of the eponymous Stanfield Organization in the Baltimore drug trade.
 Marlo's organization starts out small-time, operating in the vacuum left by the Barksdale Organization, and rises to the top of the Baltimore drug trade fairly quickly.
 A repeated theme in Marlo's characterization is his demand for unconditional respect, which trumps all other concerns.
 He frequently orders the deaths of those who disrespect him or undermine his name on the streets, however unwittingly.
 He is arguably the most violent and ruthless of the drug kingpins portrayed in "The Wire"; In 2016, "Rolling Stone" ranked him #2 of their "40 Greatest TV Villains of All Time".

 Randy runs a small business selling snacks and drinks to his peers and neighborhood drug dealers.
