Simon Adebisi is serving life without the possibility of parole for beheading an undercover police officer with a machete four years prior to the events of the first episode. A monstrous giant of a man, he often uses physical intimidation to impose his will around the prison, not afraid to assault, rape or even kill anyone who stands in his way. As one of the leaders of the Homeboys (the main black gang in Oz), Adebisi is considered one of the prison's most dangerous inmates, and becomes one of the most recognizable characters on the show. He is well known for his trademark tilted hat, which Akinnuoye-Agbaje suggested was inspired by the "Area Boys" of Lagos, Nigeria.
