Theodore “T-Bag” Bagwell
Theodore “T-Bag” Bagwell is a fictional character played by Robert on the Fox television series Prison Break, which premiered in August 2005 and ended in May 2009 after four seasons. The story revolves around a man who was sentenced to death for a crime he did not commit and his brother’s elaborate plan to help him escape his death sentence.

- Crime: 6 counts of kidnapping, rape, and first degree murder
- Sentence: Life without parole
- Education: Unknown
Theodore Bagwell, or T-Bag, has been in and out of jail since he was a boy. As a boy he was often caught vandalizing and being cruel to animals. While in fourth grade he attempted to set his teacher’s house on fire and was sentenced to juvenile hall. While there, he became a member of the Alliance for Purity, a white supremacy group. As an adult T-Bag started committing more serious crimes such as battery, assault with a deadly weapon, attempted murder, murder, rape, and kidnapping.
T-Bag was sentenced to life in prison for kidnapping, rape and murder at Donaldson Prison in Alabama. He quickly became the leader of the Alliance for Purity inside the prison, and under his leadership the gang became so powerful inside the prison the warden disbanded it and sent T-Bag to Fox River. Upon seeing that there were no Alliance for Purity members at Fox River he started a new chapter of the gang, its growth granting him significant influence within the prison. He has no qualms about seeking sexual gratification from other inmates, often preying upon younger men to rape them.
His behaviour is attributed to the environment he grew up in. According to Captain Bellick, T-Bag’s father raped his sister, who had Down Syndrome. Bellick tried to insult T-Bag and referred him as an “inbred child of a retard”.
