Supreme Allah (real name Kevin Ketchum) is a fictional character of the HBO drama Oz. He is portrayed by Lord Jamar of hip hop group Brand Nubian.
Prisoner #00K251. Convicted March 22, 2000 - Second degree murder. Sentence: 25 years, eligible for parole in 10.
A Five Percenter, he is serving time for murdering Gray Daniels, a man who laughed at him during a dice game. He often preaches Five Percenter philosophy while simultaneously dealing drugs. It is revealed that Supreme is responsible for the incarceration of Augustus Hill, having revealed Hill's location to the police after they picked him up on an old arrest warrant. As a result, Burr Redding, Hill's adopted stepfather, hates Allah. Despite his numerous enemies, lack of real allies, and his controversial and occasionally contradictory beliefs, Supreme survives numerous murder attempts, though he is killed eventually. It is possible that Ketchum's character and religion are a reference to Kenneth "Supreme" McGriff, a Five Percenter who ran the New York City based Supreme Team drug organization. (Lord Jamar, who portrays the character, is himself a Five Percenter.)
Supreme arrives in prison sponsored by Kareem Saïd. He is viewed as a threat by the Muslims since he preaches things that are as corrupting as they are enhancing. Rooming with Poet, he finds himself an ally to Simon Adebisi and the Homeboys. Since the Muslims are being led by Zahir Arif, Supreme claims Arif is nothing more than a "Kareem Saïd wannabe," and he attempts to convert a few members such as Nacim Bismilla. When Arif asks Adebisi to kill Supreme, Supreme and the other Homeboys tell Arif to watch where he walks. Being on Adebisi's good side while Oz is under the management of Martin Querns, Supreme is having a good time in Em City, not worrying about anything for the most part. Querns even names him and Poet trustees when the Italian and Latino inmates are transferred out of Em City. Supreme informs the black inmates (mainly Leroy Tidd and Mondo Browne) that they are being out-sold in drugs by Jamaican inmate Desmond Mobay whom he and Adebisi don't fully trust. This situation builds into tension between Supreme and Browne. Adebisi steps in to stop them from fighting. With only a few white inmates left in Em City, Ryan O'Reily and Christopher Keller (both white) conspire to disrupt Querns' system. They first murder Nate Shemin and then Mondo Browne. They successfully frame Supreme for the murders by planting Supreme's necklace at the scene and the murder weapon in Supreme's pod. The evidence is enough for Querns, who allows Supreme to be beaten by Adebisi and the all black correctional officers for ending Quern's streak of no violence. Supreme is sent to isolation and will stand trial for two counts of murder.
