Simon Adebisi is serving a life sentence without parole for beheading an undercover cop with a machete. An extremely muscular man, he can physically intimidate many of his fellow inmates. As one of the leaders of the Homeboys (The 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.
