Simon Adebisi is a fictional character played by Adewale Akinnuoye-Agbaje on the HBO dramatic series Oz. Initially a side character, Adebisi later serves as one of the main characters in the first four seasons, beginning with the fourth episode of the first season where he is eventually promoted to leader of the Homeboys gang. After the first half of season four, his character was killed off the show so Akinnuoye-Agbaje could film the movie The Mummy Returns.A ruthless Nigerian inmate with a penchant for rape, murder and physical intimidation, Adebisi controlled much of the drug trade at one point and is among the most feared and powerful inmates in the prison. Throughout his time in Oz, Adebisi is seen to have both sociopathic and maniacal tendencies, showing little to no remorse for the various atrocities he had committed both in and out of prison. He is also shown to have a severe addiction to heroin, suffering a nervous breakdown due to withdrawals in season 2, for which he is subsequently thrown into the psych ward where his insanity is further explored through various psychotic episodes. Adebisi's character dies in season four, when he is killed by Karim Saïd in self defence.
