Theodore 'T-Bag' Bagwell

A sadistic rapist and murderer, T-Bag Bagwell was one of the cruellest and most terrifying inmates at Fox River.

Raised by a vicious and abusive father, T-Bag was fond of torturing animals when he was a youngster. He was later convicted of trying to set fire to a teacher's house and, while serving time in juvenile detention, became involved in a white supremacist group. He did try to redeem himself at one point, having a surprisingly tender relationship with a single mother and her kids. However, she notified the police when she learnt he was wanted for murder and rape, and he embraced his dark side with renewed gusto on arriving at Fox River.

After learning of the escape plan, T-Bag threatened to inform on Michael if he wasn't included. As with the other members of the group, T-Bag was left stranded at the end of season one when the escape plane took off without them.
