Sasha (Sonequa Martin-Green) is Tyreese's sister. She travels with her brother's group to the prison and eventually to Woodbury, where she becomes a guard at Woodbury's walls alongside her brother. She is a truer shot than her brother, and with Tyreese, decides to stay behind with the people of Woodbury to protect them instead of joining the Woodbury army's attack on the prison. They let Rick's group in after Karen explains The Governor's onslaught on his men. Sasha, along with Tyreese, Karen, and other citizens of Woodbury are taken in by the prison group.
